Online Correction of LED Module Phosphor Glue

Wang Yuyang;Foshan Hang Guang Electronic Technology Co.,Ltd.;  
White LED as a new type of lighting has been widely used in all walks of life, but its key production process in the dispensing process of product consistency is a key issue to limit the LED production capacity. In this paper, a kind of LED module phosphor patch online patch program, through the dispensing, measurement, filling the process program to solve the initial dispensing deviation from the target color coordinates of the problem. Based on the theory of chromaticity modeling, the correspondence between the peak power of LED chip and phosphor and the dispensing volume V_1 is established. And the dispensing amount V_2 of the target color coordinate point is calculated based on the correspondence relationship. The experimental results show that the proposed scheme can effectively improve the color consistency of LED module and improve the product quality.
