While the lighting industry is still arguing about the luminous flux and technical route of CSP, CSP LED technology has made steady progress in car lights. The current car light products, if CSP LED light source is not used, are really outdated products.
Take a look at the technical advantages of CSP LED:
1. Better heat dissipation
2. High lumen density can reach a higher lumen value with the same device
3. Omit the wire bonding process and improve product reliability
4. High packing density
5. Adopt SMD bonding to simplify the substrate
6. Flexible fit method
7. Flip-chip LED chips are more impact resistant than formal LED chips
Due to the outdoor use of car lights, the bumps on the road, the instability of the car power supply, the impact on the LED, etc., just the 7 major technical advantages of CSP, each of which is now a must for car light products. Therefore, in the first-line car installation market, mainstream companies have already entered the system. LED lights are a standard component of the car, but for the old cars that are already on the road, car owners must keep up with the fashion and switch to LED lights, so LED after-installation is created. The booming market (AM).
In the automotive lighting aftermarket, CEC H7 bulbs are the most common. LED manufacturers follow this specification and produce H7-style light sources of CSP LED light sources, which directly replace traditional tungsten bulbs on cars. In the early days, SMD light source was used, and later progressed to using COB light source. Later, it was found that CSP was more stable. In a short period of time, CSP became the only light source of choice for car lights. Also because of the use of CSP light sources, this appeal point further pushes up the selling price.
