Automobile headlamp based on LED (light-emitting diode) three-dimensional encapsulation
2012
The utility model discloses an automobile headlamp based on LED (light-emitting diode) three-dimensional encapsulation, comprising a reflecting mirror and an LED three-dimensional encapsulation light source which is arranged in the reflecting mirror, wherein the LED three-dimensional encapsulation light source comprises a base, the base is provided with at least two light-emitting areas which can independently control light, each light-emitting area is composed of at least one LED chip mounting surface, all LED chip mounting surfaces face different directions, each LED chip mounting surface is provided with an LED chip, the LED chip is covered by an encapsulation body, and the inner wall of the reflecting mirror is opposite to each LED chip mounting surface. According to the utility model, the reflecting mirror and the LED three-dimensional encapsulation light source are arranged, and the light source is provided with at least two light-emitting areas which can independently control light, thus LEDs in one or some light-emitting areas are controlled to light up but the LEDs in other light-emitting areas are controlled not to light up, and thus the effect of changing the light emitting direction or angle of an automobile headlamp is achieved in cooperation with the design of the reflecting mirror; light source transmission distance also can be controlled, and a high beam light and a low beam light can be integrated into the same light source; and lighting requirements in different environments can be met.
