摘要
Abstract
Taking quartz glass as substrate,we used Spin coater machine to help coating phosphor on the substrate by rotating centrifugal effect.Making test lamp of continuous and adjustable distance from the chip to phosphor sheet,we researched effects of the distance and current to remote phosphor LED.When the current is small,we found that the emitting efficiency reached 106.18 lm/W which could replace most of the small power application,and the emitting efficiency reached 93.32 lm/W in a high power,with that the color rendering index was 85.2,and the correlated color temperature ranged from 4809K to 6690K.The design of the adjustable test device had reference value to the development for different environment of LED lamp.The establishment of the parameter t could help do sensitivity analysis,which had the guiding sense to the important parameter of coarse to LED lamp.关键词
