LED芯片激发荧光粉合成白光照明光源显色性的控制

Color Rendering Property Control Methed on White Lighting Source Synthesized by Phosphor Excitated by Blue LED Chip

光通量、色温和显色性是光源的三大重要指标。半导体LED从指示、显示应用过渡到照明应用,产品的显色性控制和评价是一个新的课题。本文应用光源显色性原理分析影响产品显色性的因素,并通过相关的试验,探讨如何通过材料选型和工艺措施,控制由蓝光LED激发荧光粉合成白光LED的显色性,使之达到预定指标。

Luminous flux, color temperature and color rendering property are the three main index in light source. For semiconductor LED, the control and evaluation of color rendering property is a new subject from its indication, display application to lighting application. This article applies the principle of light source color rendering property to analyze the factor that affects the color rendering property, it also discusses how to control LED light source color rendering property processed with white lighting source synthesized by phosphor excitated by blue LED chip, thus reaching the predicted index.
