When a vehicle runs at night, the headlight needs to have the function of switching between high beam and low beam, and in the conventional vehicle headlight, the high beam and the low beam are mainly switched by irradiating different parts of the reflector cup by a light source in the headlight. The light source irradiates the upper part of the reflecting cup, and the headlight of the vehicle irradiates near light; the light source irradiates the lower part of the reflecting cup, and the vehicle headlamp irradiates the high beam. When the headlight of the vehicle shines the near light, a wider position needs to be shined so as to be convenient for seeing the surrounding environment clearly. When the vehicle headlamp is used for illuminating far light, more concentrated illumination is needed so as to illuminate a longer distance.

When the automobile lamp is in near-light operation, the LED light sources arranged on the three convex mounting surfaces emit light, the LED light sources irradiate the upper part of the reflecting cup, and the LED light sources arranged on the convex mounting surfaces are in an outer-circle annular layout, so that the light reflected by the reflecting cup irradiates a wider position, and the surrounding environment can be seen clearly; when the car lamp high beam works, the LED light source arranged on the concave mounting surface emits light, the LED light source irradiates the lower part of the reflecting cup, wherein the LED light-emitting concave mounting surface is in an inner circle annular layout, and the high beam LED light source arranged on the concave surface is close to the focal position of the car lamp reflecting cup, so that the light reflected by the reflecting cup irradiates a more concentrated position far ahead of a car. Practice proves that the LED car lamp produced by the structure has high luminous efficiency, wide irradiation at low beam and concentrated irradiation at high beam, has great advantages compared with the existing LED car lamp light source structure, can be installed on different vehicles by replacing applicable lamp caps or clamping seats of different vehicle types, and has wide market application prospect.
