A transmissive blue light laser lighting component

Abstract

The invention relates to a laser lighting component, in particular to a transmissive blue laser lighting component which is of multilayer structure and which comprises a light scattering layer, a baseplate and a light-emitting layer sequentially from bottom to top; the light scattering layer, the base plate and the light-emitting layer are connected in sintered manner; the light scattering layeris made with a glass material having microporous structure; the glass material with the microporous structure is made by mixing well low-melting-point glass powder and hollow alumina microspheres, adding a volatile material to obtain a slurry, and sintering; the base plate is made with alumina or zinc oxide or quartz with surface coating; one side of the base plate is coated with an antireflectivefilm with enhanced blue light transmission; the other side of the base plate is coated with an antireflective film with enhanced yellow light reflection; the light-emitting layer is made with a glassmaterial containing phosphor; the glassy light-emitting layer is made by mixing well the low-melting-point glass powder and phosphor, adding a volatile material to obtain a slurry, and sintering.

Description

technical field [0001] The invention relates to a laser lighting assembly, in particular to a transmission type blue light laser lighting assembly. Background technique [0002] Lighting technology continues to advance with the progress of society as a whole. From the initial reliance on animal and vegetable oils and fossil fuels, to incandescent lamps and gas discharge lamps (fluorescent lamps), in the 1990s, relatively energy-saving and efficient LED white light lighting became popular. Recently, as the cost of laser diodes has gradually decreased and their performance has stabilized, it has gradually become possible to use lasers as illumination sources. [0003] Laser lighting is divided into visible light laser lighting and infrared laser lighting. [0004] Visible light laser lighting is divided into the following two types according to the principle: blue light excites fluorescent substances to realize white light lighting or red, green and blue laser synthesis whit...

AI Technical Summary

Problems solved by technology

[0011] In short, at present, in all the disclosed technical solutions, the following problems cannot be solved: the fluorescent substance used in the components for realizing blue-ray laser illumination, the part responsible for emitting light also undertakes the function of breaking up (by making micropores) the blue-ray laser, Therefore, the problems of heat dissipation, heat conduction and laser spot uniformity cannot be balanced at the same time

That is to say, all the currently disclosed technical solutions are compromised technical solutions, which can only control the micropore density as much as possible, so that the heat dissipation and thermal conductivity of the fluorescent material are not reduced to an unacceptable level when the light spot is uniform. , but this is based on the premise of reducing the overall light efficiency of the laser lighting device
