Embodiment Construction

[0025] see figure 1 As shown, the intelligent laser light source module 1 provided by the first preferred embodiment of the present invention is used in a vehicle light (not shown in the figure), and includes: a laser light device 10, a liquid crystal Panel 12, a light transmission device 14, a wavelength conversion device 16, a heat dissipation device 18, and a projection device 20, wherein:

[0026] The laser light device 10 has a plurality of laser light emitters 22 and the same number of collimators 24 as the laser light emitters 22 . In this embodiment, each laser light emitter 22 is a blue laser light emitter capable of emitting blue laser light with a wavelength between 360 nanometers and 480 nanometers (nm). A collimator 24 is respectively arranged in front of each laser light emitter 22, and each collimator 24 collimates the blue laser light emitted by its corresponding laser light emitter 22, so that it changes into an approximately parallel light. form to enter th...

Abstract

The invention discloses an intelligent laser automobile lamp light source module. The intelligent laser automobile lamp light source module sequentially comprises a laser light device, a light transmission device, a liquid crystal panel, a wavelength conversion device, a heat dissipating device and a projection device. The laser light device is provided with at least one laser light emitter whichgenerates laser light, and the laser light is transmitted to the liquid crystal panel; the light transmission device transmits the laser light emitted by the liquid crystal panel to the wavelength conversion device; the wavelength conversion device converts the laser light into white light, and then the projection device carries out projection imaging; and the heat dissipating device is incontactwiththe wavelength conversion device for absorbing heat generated by wavelength conversion, and meanwhile, the heat is dissipated to the outside.

Description

technical field [0001] The invention relates to an illuminating device, in particular to an intelligent laser light source module. Background technique [0002] Vehicle lighting is an item related to driving safety. With the lighting equipment and technology used in vehicles, the vehicle lighting device is not only brighter, but also can increase the active safety of driving, and at the same time save more power. [0003] Take car headlights as an example: from the early light bulbs, it has progressed to filling xenon in quartz lamp tubes, electrifying with ultra-high voltage, and using the arc generated by gas discharge to excite HID light, and then progressing to the semiconductor principle of light emission. LED. Recently, laser headlights have become the development direction of major car manufacturers. Compared with LED car lights, the laser car lights equipped with it can have 1.5 times the visual recognition distance, so it can further improve safety. More important...
