CSP car light source refers to the car light that uses led (light emitting diode) as the light source. Because LEDs have the characteristics of high brightness, rich colors, low power consumption, and long life, CSP led are widely used in the automotive field.
csp package features:
(1) The csp package memory is not only small, but also thinner. The most effective heat dissipation path from the metal substrate to the heat sink is only 0.2 mm, which greatly improves the reliability of the memory chip after long-term operation, and the line impedance is significantly reduced. , the chip speed has also been greatly improved.
(2) The central pin form of the CSP packaged memory chip effectively shortens the transmission distance of the signal, and its attenuation is reduced accordingly, and the anti-interference and anti-noise performance of the chip can also be greatly improved, which also makes the CSP access time ratio. BGA improved by 15%-20%.
(3) In the CSP packaging method, the memory particles are soldered to the PCB board one by one through solder balls. Due to the large contact area between the solder joints and the PCB board, the heat generated by the memory chip during operation can be easily removed. Conducted to the PCB board and dissipated.
CSP light type selection
A good light pattern divides bright areas and dark areas to help identify the road conditions on the right, and at the same time, it will not illuminate the eyes of oncoming drivers. This is determined by the overall design of the lights. To know the effect is to test the lights. Color temperature is a physical quantity used to define the color of a light source in lighting optics. It refers to the color change felt by human eyes under different energies of light waves, and refers to the color of light. This can be seen directly from the parameter box.
The more blue the light color, the higher the color temperature; the redder the lower the color temperature.
3000K yellow light, strong penetrating power; 4300K white with yellow, balanced brightness penetration;
5000K light is completely white, which is the highest color temperature of the European standard;
6000K light is completely white, slightly bluish;
7000K white is obviously bluish ;
Blue light above 8000K. Therefore, i
t is more suitable to choose LED headlights with a color temperature between 4300K-6000K,
which takes into account both brightness and penetration. It can not only meet the needs of night driving lighting,
but also do not need to worry about the penetration of light in rainy and foggy weather.
At present, there are more and more car lamp beads on the market. The main CSP lamp bead models are (CSP1860, CSP2016, csp3570 light source, CSP high-power light source special car leds), high brightness, low light decay, using its characteristics can be designed Thin, light and compact lamps of various styles provide space for car styling design.
