Composite light for vehicles

The present invention relates to a composite lamp, and more particularly to a composite lamp for a vehicle that is mounted on a vehicle and has at least two illumination and/or warning functions.

Composite lights are usually installed on vehicles or boat trailers to provide two or more functions, such as reverse lights, brake lights, flashing warning lights, direction lights, tail lights, small lights and license plate lights. It is required to combine at least two functions of a rear lamp, a brake light, a warning light, a direction light, a tail light, a small light, a position light, and a license plate light.
A composite lamp for a conventional vehicle generally includes a lamp holder, at least two light sources installed in the lamp holder, and a reflector. The front end of the socket has an opening, and the opening is provided with a light-transmitting lamp cover. The reflector is generally bowl-shaped and comprises a wide and narrow reflective surface, and the reflective surface is coated with a plating layer for reflecting light that cannot be illuminated on the working surface. The light source generally comprises a light-emitting element such as a light-emitting diode or a light bulb. The light source is mounted on the bottom of the reflector and faces the light-transmitting lamp cover. When the light source emits light, part of the light can be reflected by the reflective surface of the reflector and will be emitted by the light-transmitting lamp cover. In order to improve the lighting. However, in order to make the light of the light source located at the bottom of the reflector can be effectively reflected, the height of the reflector must be increased, resulting in an increase in the cost of the composite lamp and a large volume; that is, if the height of the reflector is not increased, the light source The light will not be effectively reflected by the reflector.

Accordingly, the main purpose of the present invention is to provide a composite lamp for mounting on a vehicle and having at least two illumination and/or warning functions, and at the same time, the light emitted by the composite lamp can be effectively reflected and utilized.
