LED Junction Temperature Test System

HP8810 LED Junction Temperature Test System

LED Junction Temperature Test System can perform the integration testing on optical, color, electricity and thermal, meanwhile track the changing curve of the parameters with time. Junction Temperature is a critically important parameter for high reliability LED applications. Because both of lifetime and luminous output are directly proportional to junction temperature. Thermal parameter is the key index to evaluate the quality of LED.
