Application of COB LED in automotive lighting

‌The application of COB LED in automotive lighting is mainly reflected in headlights and aftermarket. COB LED technology directly mounts LED chips on circuit boards to form a planar light source with excellent luminous efficiency and high luminous flux, which is suitable for headlights and can provide bright and uniform light. However, COB LED also has some challenges, such as the beam shape and brightness distribution may be affected by stray light and glare, and heat dissipation problems may also affect its reliability.

Advantages and Disadvantages of COB LED in Automotive Lighting

Advantages:

High luminous efficiency: COB LED technology has excellent luminous efficiency and high luminous flux, which is suitable for headlights and can provide bright and uniform light.

Lower cost: COB LED makes automotive headlight bulbs at a lower cost.

Disadvantages:

Stray light and glare: COB LEDs will generate more stray light and glare during use, which will affect the beam shape and brightness distribution, and may even bring safety hazards.

‌Heat dissipation problem‌: Blindly increasing the luminous flux will lead to aggravated heat dissipation problems, affecting reliability and service life‌.

Market status and future trends of COB LED in automotive lighting

‌Market status‌:

‌Fierce price competition‌: COB LED has fierce price competition in the automotive market, especially in the aftermarket market. Many manufacturers frequently engage in price wars in order to compete for market share, resulting in a compression of profit margins‌.

‌Reliability problem‌: Early COB LED products performed poorly in the automotive market and had many reliability problems, resulting in a significant decline in market usage‌.

‌Future trends‌:

‌Technological progress‌: With the continuous advancement of technology, the problems of COB LED in heat dissipation and optical design are expected to be solved, and it may find wider applications in the field of automotive lighting in the future‌.

‌Market segmentation‌: COB LED may find new application opportunities in specific market segments, such as headlights of high-end models, etc.‌

In summary, the application of COB LED in the field of automotive lighting has certain challenges and limitations, but with the continuous advancement of technology and the gradual standardization of the market, its application prospects are still worth looking forward to.
