Chen Chaozhong - Clarifying the Essence of LED Light Source Luminous Efficacy and LED Luminaire Efficiency

This article explainsLED light source luminous efficacy andLED luminaire efficiency, essentially revealing the difference between the two. In view ofLED light sources conducting luminous efficacy competitions, the trend of pursuing luminous efficacy has spread fromLED light sources toLED luminaires, emphasizing that forLED luminaires, attention should be paid to efficiency while coordinating with other performance requirements. Luminaire efficiency should be based on comprehensively satisfyingLED all performance indicators of LED luminaires.
