LED light module

The present invention is an LED lighting module applied to a vehicle headlight, especially an LED lighting module that can directly replace a conventional light bulb installed in a lamp housing without changing the original lamp housing of the vehicle.

LED lamps are widely used in the field of lighting because of their high brightness, small size, long service life and low power consumption. For example, they are used in warning lights, traffic lights, and large advertising billboards. Controlling the LED light source to produce a directional light or warning effect, or the LED light array is followed by a circuit board for timing control to produce a flickering advertising effect.

Although LED lights have become a trend to replace traditional light bulbs, the main headlights of the vehicle are still traditional halogen bulbs and xenon bulbs. The main reason is that the bulbs of the headlights must be installed inside the waterproof lamp housing from the inside out. High-brightness LED lights with different illumination positions are easy to reduce the brightness or even damage of LEDs due to overheating. Compared with the general lamps, there are still some doubts about the safety of LEDs. Difficulty.

As shown in the first figure, the conventional light bulb used in a vehicle headlight has a front end of the light-emitting unit 1 having a different light-emitting position for switching between the high-beam and the near-light, and a fixing unit is disposed behind the light-emitting unit 1 for fixing. The fixing piece 2 on the lamp housing is provided with a connector 3 which can be inserted into the power plug of the vehicle behind the fixing piece 2; wherein the shape of the fixing piece 2 and the connector 3 may have different specifications due to the vehicle label, It is limited to the one shown in the figure.

In the above-mentioned conventional waterproof lamp housing, a reflector having a condensing concave portion is disposed in the casing, and a bottom of the reflector has a receiving hole. The conventional bulb penetrates into the reflector from the back of the accommodating hole, so that the illuminating unit is located at the center of the reflector. When the conventional light bulb is bright, the light is concentrated by the condensing concave portion, and then the light source is projected by the reflector, so that different light-emitting positions on the light-emitting unit may affect the reflector The angle of the light is emitted, so that the headlights of the vehicle produce the functions of the high and low lights.
