[ background ] A method for producing a semiconductor device
The car light is the important component of car, and it can provide the illumination when the car is gone under the condition such as light is not good, haze weather or night. The LED vehicle lamp is a vehicle lamp using an LED (light emitting diode) as a light source. Because the LED has the characteristics of high brightness, rich color types, low power consumption and long service life, the LED is widely applied to the field of automobiles.
However, when the existing automobile lamp in the market is used, the lamp does not have the function of heat dissipation, and if the heat generated by the lamp in use cannot be discharged, the lamp can be damaged in long-term use.
The utility model is provided for overcoming the defects of the prior art.
[ Utility model ] content
