A car lamp with integrated far and near light

Abstract

The invention discloses a vehicle lamp integrating far and near beams, comprising a low beam module, a high beam module, a heat dissipation module, a shading plate and a lens. The heat dissipation module is composed of a first heat dissipation substrate, a second heat dissipation substrate and a radiator structure, wherein the first heat dissipation substrate is continuously bent and formed into a first lateral surface and a second lateral surface with a height drop, and the second heat dissipation substrate is connected to the first heat dissipation substrate and the heat sink near the outer end of the first lateral surface The low beam module and the high beam module are discretely mounted on the first heat dissipation substrate and the second heat dissipation substrate, and the height of the first light-emitting surface and the center height of the second light-emitting surface are both coincident with the optical axis of the lens or They are respectively biased on the upper and lower sides close to the optical axis of the lens, and the light emitted by each light source is shaped by the shading plate and collimated by the lens. By applying the vehicle lamp of the present invention, the independent heat dissipation channel is used to improve the heat dissipation effect, avoid excessive temperature in the lamp and affect the service life, reduce the volume of the vehicle lamp, and improve the light energy utilization rate of the entire lighting system.

Description

technical field [0001] The invention relates to a light source device, in particular to a vehicle lamp which is applied to the forward lighting of vehicles and integrates far and near light sources into one, belonging to the technical field of lighting. Background technique [0002] Existing conventional LED far and near beam integrated automotive headlamp structure, such as figure 1 As shown, it is usually composed of a low beam LED light source module 1 , a high beam LED light source module 2 and a lens 3 . However, the headlight structure and its lighting system have many deficiencies in practical applications, which are mainly reflected in the following aspects. [0003] First: the low beam LED light source module 1 and the high beam LED light source module 2 are arranged on the upper and lower sides of the same heat dissipation substrate, and the low beam LED light source module 1 and the high beam LED light source module 2 are on both sides of the heat dissipation sub...
