[Abstract]:White light lighting plays a very important role in human life and production activities. The light source based on semiconductor laser white light lighting has the advantages of small volume, low energy consumption, stable light color and long working life. It is of great significance to study the new generation of solid-state illumination light source. In this paper, the blue laser is used to stimulate the yellow phosphor to synthesize white light. The excitation light source is 447nm laser diode, the phosphor is YAG yellow phosphor, in order to improve the color rendering of the light source. The influence of the concentration and thickness of phosphor on the chrominance characteristics of white light source was studied. The optimum color temperature of the sample was 4637 K. The color rendering index is 71.6.2.The effect of the shape of phosphor on the color uniformity of white light source is studied. The results show that the light source color temperature uniformity of flat convex lens phosphor is the best. The color temperature uniformity of the light source of the dome type phosphor is the second, and the color temperature uniformity of the circular phosphor is the worst. 3. The effect of the addition of red phosphor to the yellow phosphor on the color rendering index of the light source is studied. It is found that by adding red phosphors, the color rendering index of the light source is obviously increased, the maximum is 83.4.4.The effect of different driving current on the chrominance characteristics of the light source is studied and analyzed, the results show that. Under different driving currents, the color coordinate, color temperature and color rendering index of the light source vary very little, but the color coordinate is different. Yx? ? ? The light source is very stable .5.Using Tracepro optical simulation software, the suitability package of semiconductor laser white light source is designed. A semiconductor laser white light source with a luminescence angle of 20 o was obtained.
