As the led headlight development for 3 years till now ,it has update from all in one design ,optional colors design,fanless design and to the current cob design ,all of this is the prove of the led headlight rapid development
What is COB?
COB (Chips on Board) is a new technology of LED packaging of LED light engine. Multi LED chips are packaged together as one light module. When it lights up, it looks like a lightinpanel.

How COB LED light source works?
In COB lighting, single LED chips are placed directly on a circuit board (or substrate) which has thermal properties to disperse heat. Heat dissipation is a very important aspect of LED lighting since it can have a major impact on the life expectancy of the luminary. Therefore, COB lighting can have a higher LED chip density and achieve higher light level while maintaining or improving life expectancy.

Advantage of COB:
COB lights are a more efficient form of LED lighting for general or automotive lighting applications because:
- light has a more uniform appearance
- better life expectancy
- achieve higher light level over a large area
- COB is more stable and reliable than standard LED package

3.Top 10 reason for choosing LED Headlights for cars
LED headlights are on the rise, and motoring commentators expect that more vehicles will sport LEDs into the future, as manufacturers and car owners alike trend away from cheaper, less-efficient bulbs. There are dozens of reasons to make the switch to LED headlights for a better motoring experience, and given the increasingly accessible cost of these once-expensive headlights, it is becoming ever-more affordable for people to upgrade.
If you’re thinking about making the switch to LED headlights, here is a run-down of the top 10 reasons people are choosing to upgrade, and the advantages you can benefit from, simply by switching out your old headlights for an LED headlights kit.
20mins installation
LED headlights kits are easy to install, and you don’t need to be a mechanic or have any particular technical skills to install these on your own car. In fact, it is possible to fit headlights with minimal tools and around 30-60 minutes of your time, saving on the labor costs of getting your headlights fitted out. Or, if you don’t feel confident installing these yourself, you can also take your kit to any mechanic, who will be able to fit these at low cost. All our kits come with full installation instructions too, guiding you through the process step-by-step to installing your headlights.
No need start up time
As the HID/xenon headlamp for car need the ballast to get a higher voltage at 22000V to start the headlight, usually it will need 1-10 seconds
While LED headlamp doesn’t have this problem now and it can work at once after you install of it ；
Longer lifetime
The average LED light can be used continuously for 11 years, or 22 years at 50% activation. That compares with just 5000 hours for a typical halogen headlight, which are also more prone to failure over the course of their life, on account of their moving parts. LED headlights are therefore significantly more hardwearing and long-lasting than traditional halogens, which remains a key element of their appeal.
Engery Save
Because LEDs are so much more energy efficient than halogen and other headlights, they draw less energy from your vehicle to produce a purer quality of light. This has the net effect of improving your fuel efficiency, which will save you money. When you multiply these marginal savings over the full lifecycle of your LED headlights, this money goes some way towards repaying the cost of your headlights kit.
These are just a few reasons more motorists are choosing to switch to LED headlights, and industry projections expect an increasing number to switch to LED headlights in the years to come. For a long-term, efficient, high quality solution for any car, choose LED headlights in preference to standard halogen bulbs.
Friendly Environment
The HID/Xenon car headlight bulbs has mercury inside of it ,while mercucy is harm to environment and people ,so now many countries are banned for HID headlight,such as USA
LED has solved the problem of it ,it doesn’t have any harmful substance
No Need To Replace Bulbs
Of course, not replacing your headlights or bulbs is in itself an advantage, saving you the effort of switching out your headlights on a regular basis. This means there is no need for ongoing maintenance to your headlights, or for periodic refits if a bulb blows. This saves time and hassle on the replacement process, so you don’t have to switch out your bulbs every year or so - not to mention saving additional expense.
More Efficient Lighting
In terms of the lighting LED headlights produce, it is created with significantly greater efficiency than with halogen bulbs. Whereas halogen bulbs waste 80% of their energy (by generating excessive heat as a byproduct of creating the glowing light), LED lights convert 80% of the energy they use directly into light, wasting only 20% in the process - significantly more efficient. This means you can benefit from stronger lighting, with a lesser load on your alternator.
Cheaper To Operate
Because LED headlights are significantly more efficient, they are cheaper to operate. Further, because you may only have to replace LED headlights as often as you change your car, they are significantly cheaper to buy and maintain over the total lifecycle of your headlights. This represents several cost savings over halogen bulbs, which manufacturers use because their initial component cost is lower than with LED headlights. So as well as benefiting from more effective lighting on the road ahead, you can also save money into the bargain.
Build Quality
Our solid-state LED headlight kits are built to exacting standards, ensuring they can realise their full potential over long-term use. With no moving parts, as with traditional bulbs, you are much less likely to need to switch out your headlights over the course of their lifecycle. Our high-quality components are manufactured to last, so when you switch in your LEDs, you can rest assured in the quality of your headlights.
Safer To Use
Consider a night-time driving scenario, or foggy road conditions. Rather than a weak, yellow halogen light which illuminates just a few feet directly ahead, or even reflects against dense fog, LEDs produce a much more penetrating, illuminating white light. This results in clearer driving conditions ahead, while making it much easier to see in fog and other poor visibility conditions. As a result, drivers with LED lights have more time to react to changing conditions ahead, and therefore can be sure they are as safe as possible on the roads.
Better Lighting Quality
Aside from being brighter, that actual quality of light from LEDs is greater than the quality of light available from halogens. Rather than a weak, watery yellow light, LEDs produce a much more piercing, clearer quality of light. This is warmer than HID xenon bulbs too, so more illuminating and less blinding for other road users. For the optimal lighting quality from your headlights, choose LEDs.
