Description

Composite uniform light

technical field

The invention relates to the technical field of automobile lamps, in particular to a composite uniform light vehicle lamp with a composite uniform light system.

Background technique

The optical system includes a light-emitting element, a light guide system, and a uniform light system. The light guide is used to guide the light emitted by the light-emitting element to the light-emitting surface of the light guide, so that the light source module forms a uniform surface light source. Light guides are also often found in the form of light guide plates. Generally speaking, common light guiding structures are mirrors and light guides.

Existing car light adopts two kinds of modes more. One is the light bulb light source plus a reflector. Sometimes an inner lens is added to make the outgoing light more uniform. Sometimes the inner lens is also patterned. The other is a combination design of LED light source and light guide panel. These existing optical system designs, either the light utilization rate is not high, need higher power bulbs, more or high power LED light sources connected in series, which increases the power consumption; or each part of the reflector and the light guide panel The light is not uniform enough, and the scattered light is not beautiful. Even if some inner lenses and patterns are added, it will not help much.

Contents of the invention

Aiming at the problems existing in the above-mentioned prior art, the object of the present invention is to provide a composite uniform light vehicle lamp with a composite uniform light system. The light is incident vertically downwards, reflected by the skin texture mirror and emitted horizontally, and some of the light is obliquely incident on the white scattering mirror. It is characterized by a large luminous area, an extremely uniform light-emitting surface, a wide range of applications, and can adapt to various modeling requirements.

The present invention provides a compound homogeneous vehicle lamp, which includes a PCB board and an LED lamp, the LED lamp is arranged on the PCB board, a Fresnel lens is arranged under the LED lamp, and a skin Aluminized reflector with texture and white scattering reflector. The aluminized reflector with leather pattern is arranged on the left side of the white diffuse reflector. A part of the inner lens coated with aluminum is arranged above the white diffuse reflector. The part of the inner lens coated with aluminum An outer lens is arranged above, and the PCB board, LED lamp, Fresnel lens, leather-patterned aluminum reflector, white scattering reflector and part of the aluminum-plated inner lens are arranged inside the lamp housing.

A further improvement is that: the partially aluminum-coated inner lens is a lens that is coated with aluminum, and the inner lens is formed by removing part of the aluminum coating by laser, and the shape of the aluminum coating on the inner lens can be adjusted.

A further improvement is that: the textured aluminized reflector is arranged obliquely, and the angle between the textured aluminized reflector and the white scattering reflector is 135°.

A further improvement is that: the outer lens is arranged at the right end of the lamp housing.

The beneficial effects of the present invention are: the light rays emitted by the multi-point light source in different directions are first aggregated and straightened through the Fresnel lens, and most of the light rays are evenly reflected by the textured reflector and pass through the part of the aluminum-coated interior. Part of the light is emitted from the lens, and part of the light is incident on the white scattering mirror and is evenly scattered by the part of the aluminum-plated inner lens. The emitted light is uniform and beautiful, and the use of white scattering reflectors can greatly improve the uniformity of the emitted light throughout the day, and at the same time make it easier for the lights to meet regulatory requirements. Part of the aluminum plated inner lens shape can be freely designed, which is extremely beautiful.
