High beam and low beam integrated headlamp

Abstract

The invention discloses a high beam and low beam integrated headlamp. The high beam and low beam integrated headlamp comprises LED light source modules, light collecting devices and a lens. High beams or low beams transmitted by the LED light source modules are ejected after being transmitted and ejected through the light collecting devices and refracted through the lens so that the matched light type of the low beams or the high beams can be formed. LED light sources are adopted for a light source of the high beam and low beam integrated design, motors or electromagnetic valve mechanisms are omitted, the module structure is simplified, and the service life of the whole module is prolonged; the response speed of high beam and low beam switching is increased, the response speed of the LED light sources is high, and therefore the response time of the module is accordingly shortened when the headlamp is switched into a high beam lamp from a low beam lamp or switched into the low beam lamp from the high beam lamp.

Description

technical field [0001] The invention relates to the field of automobile lighting, in particular to a headlamp with integrated far and near beams. Background technique [0002] At present, in order to save space and shape requirements, most cars design the high beam and low beam into an integrated structure. The traditional far and near beam lighting has an H4 light source, which includes two filaments, and uses a reflector to form an integrated design of far and near beams. There is also a projection lamp design, which uses the same light source, reflector and lens. Unlike the single-function projection lamp, the baffle can move and be in two positions, and the conversion between the two positions is completed by a motor or a solenoid valve. , this structure has a relatively long response time in the process of far and near light changes. With the development of light source technology, LED light sources have higher luminous efficiency and longer life. However, when LEDs a...

AI Technical Summary

Problems solved by technology

With the development of light source technology, LED light source has higher luminous efficiency and longer life, but when LED is used as the light source in the integrated design of far and near light, the life of the motor or solenoid valve will affect the life of the entire module

Existing headlights not only have a long response time for far and near light, but also have a short service life of the module
