Prospect of new Led auto market

According the report of D-Daily which is news agency of Korea. Estimating Led market scale will be 249 hundred million USD, And proportion of Led market will reach 57%,Especially residence and auto light which is the market has great potential, Can be create more growing rate.

According auto research agency report,High bright LED auto light appear strong growing, For long term use is safe energy,environment friendly,In auto market’s application will be great improvement.

Red LED tail light already be used in auto market more than a decade ago,But inter auto light and Led headlight is not popular until this years. For now proportion of LED application in auto inter indicator light part has 70%,background light of instrument display board has 45%,daytime light has 55%, And proportion of LED headlight is 20%. And the data of LED headlight is growing more and more fast lately.

Why the LED headlight growing so fast? Because LED has lots of advantage. Normally the bright of LED headlight is between Halogen and HID headlight,but the beam will be more spot,and also can be produced more shape of light. Moreover, LED’s size is more small, operation freeness will more high, thus customer has more optional to choice.

Why the Led headlight not popular in couple years ago?All because of the price. Except the LED headlight, and we also have incandescent light,Halogen,HID option. But the price of LED is higher than others before. The price is not really nice. But now DDL is develop a competitive price LED headlight with good quality to help our customer to occupied with their Auto LED market. And we persist in good quality and professional service to our customer.

Should We Change our lights into LED?

Drivers may soon notice brighter and whiter headlights on the road as the popularity of traditional halogen headlights continues to dim.Halogen still ranks highest as the most common headlight on the market, but several alternatives, including xenon-based and light-emitting diode (LED) headlights, are growing in popularity. Here's how the options compare in terms of performance, safety and price.

  According to Motor Trend, you'll notice several important differences in light produced by LEDs, xenon and halogen headlights. LEDs have the coolest color temperature at around 6,000 Kelvin, which makes them appear whiter than daylight. Xenon headlights come in at around 4,500 K, while halogens round out the list at a yellowish 3,200 K.When it comes to reflection, LEDs offer better light return from road signs, while xenon lamps better illuminate the sides of the road. In part, this is because xenon lamps typically produce more light, measured in lumens, than LEDs.Both LEDs and xenon provide a large pattern of light on the road, whereas halogens offer a small pool of yellow light directly in front of the vehicle. If you're buying a new car, expect LED headlights to be the premium option, and make sure your auto repair shop is equipped to handle LED headlight replacements and repairs.If you're looking for intense light and don't mind the glare, xenon may be the best choice. LEDs, meanwhile, offer great light, low power and long life, but often come with a bigger price tag.

  LEDs are the most recent innovation in headlight technology. Instead of gas and filaments, LEDs rely on small diodes that produce light when electric current excites their electrons. They need an low amount of power to work but do produce a significant amount of heat on the diode. This requires heat control systems at the bottom of the headlight and near other car components. If this system fails, not just the light, but other electronics could be affected.The small size of LEDs means they can be formed into almost any shape, and their light is naturally directional rather than diffuse, making them an excellent choice for headlights.

What are the differences of the beam pattern?

There are many types beam pattern for led work driving light and led light bar,while the most popular and widely used is these 4 types: Spot (Long Range), Driving and Spread, Fog, and Flood.

Spot Beam (Long Range): Spot or Long Range lights are able to penetrate deep into the night. KC Long Range Lights produce a tighter, more focused circular beam of light (pencil beam) to see way out ahead toward the horizon even at higher speeds. These lights create an extremely bright, hot center beam pattern. Spot beam lights are typically used for Off Highway, Commercial, Agricultural and Racing applications.

Driving and Spread Beam: Driving lights are designed to supplement your high beam headlights.  KC's Driving lights all comply to both SAE and ECE regulations and requirements and are street legal. KC Driving Lights produce a rectangular shaped beam pattern that can reach further and wider than your headlights.  Driving lights are very useful to create visibilty near the sides of roadways and out in front of the vehicle. They are great for all around trail riding as well.

Spread beam lights are similar to Driving but tend to be brighter, wider and possibly taller as they are not required to follow specific SAE or ECE safety standards.  Spread beam lights are great lights for multi-purpose off-road use.

Fog Beam: Fog lights are intended to be mounted below the headlights and project a beam pattern which is very wide horizontally and narrow vertically usually called a cut-off. This pattern lights up a pathway close to the ground but does not light the airborne particles in the line of sight while driving - this increases the visibility in harder to see conditions. KC Fog beams are very useful in Dust, Fog, Rain and Snow. They also work well as Cornering lights in clear conditions and are optically designed to increase visibility in tandem with your primary headlights.

Flood Beam: Flood beams create a large wide pattern of light that floods an area with an extremely tall vertical and wide horizontal light pattern. These lights are typically used as work lights and back-up lights to see a broader area at shorter distances.

Pls choose the right beam pattern for your application

Trapezoidal Beam:The trapezoidal beam (shown in dotted lines) is an ideal, general-purpose work light designed with a narrower pattern for longer visibility

2. Five things to consider before buying car led lighting

When your halogen car lighting is not enough bright as you want, it's a good time to consider switching to LED.

LEDs have an impressive lifespan (50000hours!) and are very cost-effective.

Now's the right time to switch to LEDs. These bulbs have made significant advances over the last few years, Because there are so many LED varieties, choosing an LED is entirely different from many types. Before you head to the store, find out what you need to know about choosing the right LED bulbs.

Lumens, not watts

Forget what you know about halogen -- your watts are no good here.

When shopping for bulbs, you're probably accustomed to looking for watts, an indication of how bright the bulb will be. The brightness of LEDs, however, is determined a little differently.

Contrary to common belief, wattage isn't an indication of brightness, but a measurement of how much energy the bulb draws. For incandescents, there is an accepted correlation between the watts drawn and the brightness, but for LEDs, watts aren't a great predictor of how bright the bulb will be. (The point, after all, is that they draw less energy.)

For example, an LED bulb with comparable brightness to a 60W incandescent is only 8 to 12 watts.

But don't bother doing the math -- there isn't a uniform way to covert incandescent watts to LED watts. Instead, a different form of measurement should be used: lumens.

The lumen (lm) is the real measurement of brightness provided by a light bulb, and is the number you should look for when shopping for LEDs.

Choosing the right color LED

You can always count on halogen providing a warm, yellowish hue. But LEDs come in a wide range of colors

As shown off by the Philips Hue, LED bulbs are capable of displaying an impressive color range, from purple to red, to a spectrum of whites and yellows. For the home, however, you're likely looking for something similar to the light that incandescents produce.

The popular colors available for LEDs are "warm white" or "soft white," and "bright white."

Warm white and soft white will produce a yellow hue, close to incandescents, while bulbs labeled as bright white will produce a whiter light, closer to daylight and similar to what you see in retail stores.

If you want to get technical, light color (color temperature) is measured in kelvins. The lower the number, the warmer (yellower) the light. So, your typical incandescent is somewhere between 2,700 and 3,500K. If that's the color you're going for, look for this range while shopping for LED bulbs.

You'll pay more for an LED bulb

LED bulbs are like hybrid cars: cheaper to operate but pricey upfront.

When switching to LED bulbs, don't expect to save buckets of cash. Instead, think of it as an investment. Luckily, competition has increased and LED bulbs have come down in price (like this $5 LED from Philips), but you should still expect to pay much more than an incandescent.

Eventually, the LED bulbs will pay off, and in the meantime, you'll enjoy less heat production, longer bulb life, and even the option of controlling them with your smartphone.

Bottom line: unless you're replacing many incandescent bulbs in a large house, you won't see significant savings in your electricity bill.

Watch out for non-dimmable LEDs

Because of their circuitry, LEDs are not always compatible with traditional dimming switches. In some cases, the switch must be replaced. Other times, you'll pay a little more for a compatible LED.

Most dimmers, which were likely designed to work with incandescents, work by cutting off the amount of electricity sent to the bulb. The less electricity drawn, the dimmer the light. But with your newly acquired knowledge of LED lingo, you know that there is no direct correlation between LED brightness and energy drawn.

This guide explains why some LEDs will hum, flickr, or buzz when tied to a dimmer.

If you'd like your LED to be dimmable, you need to do one of two things: find LED bulbs compatible with traditional dimmers, or replace your current dimming switch with a leading-edge (LED-compatible) dimmer.

When shopping for LEDs, it helps to know what kind of dimming switch you have, but if you don't know (or would rather not go through the trouble), simply search for LED bulbs compatible with standard incandescent dimmers. To make things easier for you, we tested a slew of them to find out which LED bulbs work best with dimmers.

Not all light fixtures should use LEDs

Knowing where it's OK to place an LED will ensure that the bulb won't fizzle ahead of its time.

You probably know that LED bulbs run dramatically cooler than their incandescent cousins, but that doesn't mean they don't produce heat. LED bulbs do get hot, but the heat is pulled away by a heat sink in the base of the bulb. From there, the heat dissipates into the air and the LED bulb stays cool, helping to keep its promise of a very long life.

And therein lies the problem: the bulb needs a way to dissipate the heat. If an LED bulb is placed in an enclosed housing, the heat won't have anywhere to go, sending it right back to the bulb, and sentencing it to a slow and painful death.

Consider where you'd like to place your LED bulbs. If you have fully or semi-enclosed fixtures you need to light up, look for LEDs that are approved for recessed or enclosed spaces.

3.5 steps you should know before buying led work light

A work light is used in a particular job-related situation, such as for automobile mechanics repair, theater technical setup, mining and marine applications. It can also be used for automotive lighting, patrolling, hunting and other moving environments. When you choose a work light, you’d better consider the specifications in terms of your working environment.

To judge if the LED work light you are considering is the best choice for you, there are some features that you can compare.

1) Type (Beam pattern)
The first thing you should notice is the type of light. Consider what type you want, floodlight, flashlight or off-road light. Floodlight is widely used to provide wide-angle lighting for outdoor work in construction sites and other facilities. Flashlight is widely used for emergency lighting and is usually rechargeable. Off-road light is applied to automotive lighting. So choose the type of work lamp according to the purpose of your project. Then you should narrow your choice according to the following features.

2) Size
The size of the device is critical. In certain work situations, the space is limited, so you cannot choose a bulky work light, otherwise you will not have enough space to operate. Of course, when space is sufficient, the lamp size will not be an issue.

The size is from 2inch to 9inch,pls choose the one suitable for your device

3) Power & heat output
If your work needs intense bright light especially in industrial and mining areas, construction sites and so on, you should choose a high-power work lamp. The higher the power is, the higher the intensity is. However, a higher power usually transforms to higher heat generation. If a light emits a lot of heat, the space will be too hot for the device to function properly and people will feel uncomfortable, especially in a narrow room. So you should balance the power and heat output to reach a best combination for your work conditions.

4) Power supply
Most flashlights use dry batteries as power supply. Then you will need to replace the batteries from time to time when they run out of power. Some work lights work on built-in rechargeable batteries. For this type of light, it is be important to know the operating time and the recharging time. In addition, the available chargers might influence your decision, too. A rechargeable work light is often sold with an AC charger or car charger or both.

5) Fixation. 
Another vital factor is how the LED work light is kept in position. Work lights come in varieties of designs, including bar light with a hook on one end, hand-held flashlight, floodlight with a handle, lamp on a tripod and a lot more. So find the most convenient method for you to place the work lamp and choose the best fit design and feature accordingly.

There may be other features that you need to consider, such as waterproof grade, slip-resistance, shock-proof, overcharge protection, rotation and so on.

Car Headlights: Halogen vs. Xenon vs. LED

Though the HID and LED Headlight for car has developed for many years and some are still confused of it and can not know clear of it and the difference with them

There have been a lot of advances in headlight technology since their origins as acetylene lamps back in the 1880’s. While halogen bulbs are still the most popular and commonly used today, Xenon HIDs are increasingly growing in popularity. That being said, the newest car models are more and more beginning to implement LED headlight technology. Some manufacturers, such as Audi and BMW, are even starting to experiment with laser headlights. Today, we will compare LED vs. Halogen vs. Xenon headlights and we will discuss the advantages and disadvantages of each technology.

HALOGEN HEADLAMPS

As we mentioned earlier, halogen headlamps are currently the most widely used in the automotive world. This is primarily due to two factors. First, their primary advantage is that they have a very long lifespan. Under normal conditions, a halogen light bulb has a lifespan of approximately 1,000 hours. Halogen’s second advantage is that they are relatively inexpensive to produce, thus making replacement costs relatively very low. While halogen is still the most commonly used headlight, that fact is slowly starting to change as manufacturers shift towards other technologies. Reason being that halogen bulbs are less efficient than their new counterparts. In order to help us understand why, let’s examine how halogen light bulbs work.


When the halogen light bulb comes to the end of its lifetime, it usually happens so because the tungsten in the filament evaporates and leaves the filament, getting deposited on the glass and causing the filament to rupture at some point and render itself unfunctional.

But that’s not the major issue, though. The biggest problem is that, while generating the radiating light, the bulb also creates a large amount of heat which basically represents wasted energy.

Another major problem with halogen bulbs is also the way they react to various substances. For example, when replacing a faulty bulb, it is mandatory to avoid touching the glass of the spare one! The grease on your fingers will stick to the quartz glass, causing it to heat unevenly and drastically cut the bulb’s life. It you touched it, try using a clean cloth and an alcohol-based substance to rub it off.

Still, halogen light bulbs have a number of advantages that could make it the number one option for most carmakers: they create a decent illumination for the least amount of money ; they come in a number of different sizes, which basically means that such bulbs can be installed on most car models; they are dimmable, thus allowing carmakers to build multiple versions, depending on body type and dimensions.

In just a few words, there are the pros and cons of halogen headlamp

ADVANTAGES:

easy to replace
simple construction
different dimensions
cost effective

DISADVANTAGES:

not very energy efficient

light cannot be easily focused

extra precautions required when installing

HID HEADLAMPS (XENON HEADLIGHTS)

Xenon headlights, officially known as high-intensity discharge headlamps (HIDs), are usually defined as a more efficient solution, mostly because of the color temperature 

and the amount of light they generate. The first xenon headlight appeared on the BMW 7 Series in 1991 and slowly became the number one option for several car companies, which avoided however to offer it as standard equipment.

HID lights work pretty much like your neon tube in the basement. You have an enclosed tube filled with gases, an electrode at each end and an electric current passing through. In vehicle applications, HID lamps are using a transparent quartz housing, tungsten electrodes and a mix of gases that get stimulated by the high-voltage electric current passing between the two electrodes.

Despite their commonly used name, HIDs actually use a metal-halide mix and rely on xenon gas only during start-up. That’s because one of the main problems with HID lamps is the amount of time needed for the gases inside to reach their operating temperature and provide a strong light.

The process of lightning up HID lamps happens in three steps: first comes the ignition phase, when a high voltage pulse produces a spark that ionizes the xenon gas and creates a tunnel of current between electrodes, then the temperature in the bulb rises quickly vaporizing the the metallic salts which lowers the resistance between the two electrodes; ultimately, the ballast switches to continuous operation supplying the lamp a continuous amount of power so that the electric arc won’t flicker.

Pluses? First of all, a xenon headlight is much more efficient when it comes to the amount of produced light as compared to the halogen ones. Of course, this can be easily considered a major setback, especially from the point of view of incoming traffic, if the angle of illumination isn't properly configured (mostly when aftermarket kits are installed the wrong way or using headlight cases that were not designed for HIDs).

According to official stats, a xenon bulb produces 3000 lumens and 90 mcd/m2, while a halogen light generates 1400 lumens and 30 mcd/m2. 

Of course, xenon lamps have slowly became available in a number of sizes and versions, especially to be used on various types of cars.

Another big plus comes because xenon lights have a pretty long lifetime, exceeding the one of halogen lamps: estimates are pointing to an operation life of around 2,000 hours in normal conditions.

Efficiency might be another advantage thought when thinking to choose HID detrimental to halogen lights. They do use more power to kickstart into action, but after they’ve reached operating temperature, they’ll actually use less power than standard bulbs. Which means there will be a slightly smaller load on the alternator which won’t require more engine torque to sustain the electricity demand. However, you’ll barely see any difference in fuel consumption (maybe like one fluid ounce per hour) but it’s nice to know if you’re a “greenhead”.
Setbacks? Well, obviously they’re going to cost more than halogen lights (including maintenance) and are more complex, since they require a device called ballast, which is basically a capacitor that creates and regulates the high voltage needed by the HIDs to operate.

Let’s not forget these lights need a few seconds to reach full brightness, reason why they are not that good as separate high beams. Some cars use HID low beams and separate standard bulbs for high beams. On higher end models, the same HID unit works both ways (wrongly named bi-xenon) by using a mechanical shade inside the reflector to change the beam’s direction accordingly.

Some xenon headlamps could also have a harmful impact on our health, as certain versions could contain toxic substances, such as metal mercury. Some countries have imposed special regulations that prohibit the use of such substances but, of course, this will only lead to higher production and repair costs.

Ultimately, the amount of glare generated by the headlamps might be extremely disturbing for the other drivers on the road, especially for incoming traffic, thus raising the number of accidents and fatalities caused by other than speed and technical problems.

So, to review the pros and cons of xenon lights:

ADVANTAGES:

longer lifetime than halogen lights
more efficient than halogen as they use less power and create more light
better visibility for the driver

DISADVANTAGES:
potentially distracting to oncoming traffic, due to too much glare

higher production costs than halogen

possibility of harmful or hazardous materials used in their production

Led Headlights

As the automotive industry continues to evolve, headlights in particular are advancing rapidly.  In a very short period of time, headlight technology has reached a whole new level. After HIDs had been on the market for a couple of years, car manufacturers began to analyze a new, even more energy efficient option called LEDs. LED headlight bulbs on cars first appeared in 2004, and the first car that offered full LED headlights was the Audi R8. Many would argue that LEDs seem to be the most ideal solution for mass-produced automobiles. However, there are also several drawbacks with the technology that could change their perception about this type of lighting technology.

The greatest advantage to LED headlights is the fact that they need very little power to operate. This is a huge advantage as we see more and more of a shift towards hybrid and full electric vehicles. LEDs are already being used on the Toyota Prius and on several other hybrids on which electrical power plays a key role – for more than the horn and headlights.

Let’s take a closer look at some disadvantages. Unlike halogen lights, LED headlight do not emit heat while creating light. However, what they do is they create a small amount of heat towards the bottom of the emitter. This creates creating a potential risk for nearby parts, connective cables, and assemblies. While, for this reason, car makers may be generally avoiding utilizing LEDs for headlamps, they are instead adopting the LED technology for day time running lights, brake lights, and turn signal bulbs.

Because light-emitting diodes are so small in size, they can be manipulated into a great many configurations. The shapes can be custom fit to nearly any conceivable design that the manufacturer can come up with.

The amount of energy consumed by LEDs is believed to be in between the energy consumed by xenon and halogen lamps. Producers are making efforts to improve in this area in the future.

Production costs remain a major obstacle for LED headlights. Significantly improvement in this area is needed, if they are going to be used more widely. Currently, LEDs are still fairly expensive and are usually only offered on luxury, premium vehicles.

To summarize, these are the pro’s and con’s of LED headlights:

ADVANTAGES:

smaller size enables greater flexibility for more varied shapes

turn on instantly, no warm up period

extremely energy efficient

easy to install a LED headlight conversion kit

DISADVANTAGES:

costs more to produce

lower amount of light generated

 higher temperatures are possible around adjacent parts or assemblies

After the detailed description of Halogen ,HID and LED ,is it clear to you now ?

Which will you choose for your car headlights?

2.What is the difference between high/low beam and single beam?

When choosing and buying headlight for your car,the seller will ask do you need single beam and high/low beam, many times most of us are confused and doesn’t know the difference of them.

The single beam bulbs are also known as type 1 bulbs. Most vehicles use this standard bulb design as their factory default option. This type of design actually uses two different bulbs. One bulb is for the low beam, and the other bulb is for the high beam, thus the reason for calling these single beams. When the lights are first turned on, the low beam bulbs are illuminated. When switching to high beam, both of the bulbs will illuminate. These types of bulbs are cheaper because they do not have to have any brightness controls.

When labeling bulbs, high / low beam bulbs are often referred to as type 2. These housings come with one primary bulb and one secondary bulb. Typically the primary bulb uses the Xenon technology, and the secondary bulb uses the halogen technology. In this setup, the Xenon bulb is used for normal driving conditions and the halogen bulb is used to create a high beam of light. One important thing to note about the halogen bulb in this setup is that the light from these bulbs does not actually point straight ahead. Instead, it illuminates the surrounding light to generate a high beam effect.

3.What are Canbus?

When installing led bulbs for cars ,we always get the problem: the dashboard is warning ,what happen for it? It is the problem of the led bulbs you install need Canbus

CAN Bus LED bulbs are simple plug-and- play LED bulbs which are made specifically for CAN Bus-equipped vehicles. These bulbs work with your vehicle's advanced computer system, so when your vehicle's computer reads them, they respond back correctly. 

What does CAN Bus mean?

CAN Bus means Controller Area Network Bus. This system monitors your vehicle and reports operating conditions. CAN Bus systems are commonly found in European vehicles such as BMW, Audi, Mercedes, Volkswagen, Porsche, and in many American vehicles. While most late model American vehicles have CAN Bus systems, it is always good to check with your vehicle dealer to see which system your vehicle has before purchasing electrical products.

Will CAN Bus LED Bulbs Prevent “Bulb-Out” Indication?

Each vehicle has different requirements that the CAN Bus system is looking for, but in most cases CAN Bus LED bulbs should prevent a “bulb out” indication in areas such as tail, brake, and running lights. If you use a standard LED bulb that is not

CAN Bus application, you would consistently get a “bulb out” dashboard indicator because your system can't communicate with a standard LED bulb.

Will CAN Bus LED Bulbs Prevent Hyper-Flashing?

CAN Bus bulbs will not prevent hyper-flashing of turn signals. These bulbs are communicating with the CAN Bus system, but the relay still needs an appropriate amount of load to operate correctly. Your electrical system could require load resistors or an electronic flashing relay to stop hyper-flashing. The factory relay causes the hyper-flash when it thinks there is not a bulb working. For more information, click the question "Why do LED Bulbs cause turn signals to blink so fast? Can I fix it?" above.

Can you use CAN Bus LED bulbs in non-CAN Bus applications?

CAN Bus LED bulbs should not be used in non-CAN Bus applications because in most cases they can cause other vehicle circuits to have problems. Electrical systems are much like the flowing water in a river; if a log or other obstacle is placed in its path, the water backs up, but then finds another route. A CAN Bus LED bulb presents more resistance than the stock bulb due to built-in resistors and may cause feedback into other circuits in the non-CAN Bus electrical system.
