Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] Example of auxiliary high beam module:

[0023] The auxiliary high beam module of the present invention adopts a reflective light distribution method and uses at least one laser module. Such as Figure 4 In this embodiment, two laser modules are set, and the laser modules include a laser light source, a shaping lens, a conversion device, and a reflector. The two laser modules in this embodiment are respectively equipped with a laser safety detection device. The safety detection device is provided with a reflector opening on the reflector directly above the laser light source, and a detector is placed above the reflector opening facing the laser light source, and a filter is added to the front end of the detector.

[0024] When the conversion device is broken or broken down by the laser, part or all of the blue light will leak...

Abstract

The invention relates to an automobile headlight, a laser auxiliary distance light module thereof, and a laser safety detection device. A reflector is provided with an opening, a detector is placed in the position, directly facing a laser light source, above the opening of the reflector, and an optical filter is arranged at the front end of the detector. According to the opening of the reflector, when blue light leakage occurs due to the fact that a conversion device is fractured or is punctured by a laser, leaked blue light reaches the detector through the opening of the reflector, and the detector judges whether blue light leakage occurs according to detected energy change. When laser leakage is detected, a feedback signal is sent to close the laser light source, and the laser light source is closed in time. According to the automobile headlight, the laser auxiliary distance light module thereof, and the laser safety detection device, real-time safety detection and passive safety protection can be achieved, a safety guarantee is provided for use of a white light laser source in the lighting industry, and harm to human eyes due to laser leakage is avoided. The technical problems that when an existing automobile lamp adopts a laser as a light source, the eyes of pedestrians and an opposite driver are harmed due to laser leakage are solved.

Description

technical field [0001] The invention relates to an automobile headlight using laser light as a light source, in particular to a laser safety detection of the automobile lamp, and in particular to an automobile headlight, a laser auxiliary high beam module and a laser safety detection device. Background technique [0002] With the development of light source technology, laser, as a brand new light source, has gradually entered the automobile market. Due to the high brightness of laser and the good collimation performance of laser light source itself, it is popular in the market. At present, lasers are used as light sources to make high beams and auxiliary high beam lamps appear on the market. However, the use of laser as a special light source requires extra attention. According to the description of national regulations, Class 3B and Class 4 lasers may cause permanent damage to human eyes. Improper use will cause harm to pedestrians and oncoming drivers . [0003] There is...
