The Effect of Chip’s Size on the Performence of GaN-Based LED Chips

Abstract:

Before cutting into a single chip, we have tested LED chips with different sizes that is produced on the some condition. With different drive currents, we compared the luminous intensity and working voltage about the two samples. The results show that: within a certain range, the larger chip is better. Because of low light utilization rate, it isn’t the bigger of chip area the better the performance is. We should choose the best size in application.
