Module for low and high beam integrated headlights

technical field

The utility model relates to the technical field of LED lighting, in particular to a module for a car lamp integrating near and far beams.

Background technique

In recent years, with the continuous increase of LED light efficiency and power, LED lights have also been applied to the field of car lights; compared with traditional car lights, LED car lights undoubtedly have more advantages, such as low power consumption and long life of LED car lights , good luminous efficiency, environmental protection, etc.; the existing LED car lights are usually the same as traditional car lights when dealing with the switching of far and low beams. When the near and far beams are switched, the lamp beads of different power sizes are directly switched.

Utility model content

The utility model aims to solve the deficiencies of the prior art, and to design a module for an integrated car lamp with near and far beams.

The scheme adopted in the utility model is: a module for near and far light integrated car lights, including: a reflective cup, the cup wall of which is a 1/2 ellipsoid crown curved surface, the cup wall is coated with a reflective layer, and the reflective cup is long 37mm, width 69mm, height 28mm; LED light source, located inside the reflective cup, located in the center of the spherical surface; lens, located outside the mouth of the reflective cup, the lens is a collimating lens, the lens is a spherical body, The spherical crown body includes a bottom plane and a spherical crown curved surface, and the bottom plane faces the mouth of the reflector cup; the diameter of the bottom plane of the spherical crown body is 64mm, and the thickness of the spherical crown body is 23mm; The sheet is a semi-shielding sheet, which can be movably inserted or withdrawn between the reflector cup and the lens.

When the low and high beam switching piece is inserted into the light path, it is the low beam, and when it pops up, it is the high beam. The reflector is designed with a free-form surface to reflect the light from the light source into the lens. The lens is a collimating lens, which collimates and projects the light emitted by the reflector to form near and far beam spots.

Preferably, the switching sheet for low and high beams is a frosted glass sheet, the length of the glass sheet is 49mm, and the width is 29mm.

Preferably, the edge of the insertion end of the near and far beam switching sheet has a stepped shape. The edge is in the shape of the cut-off line of the low beam of the vehicle lamp.

Preferably, the distance between the mouth of the reflective cup and the bottom plane of the lens is 52mm.

Preferably, the LED light source is a white LED light source.
