Thermal parameter is the key index to evaluate the quality of LED. Different temperature will have significant different effects on optical parameters, color parameters, electricity parameters and life of LED. Therefore, design and control of the thermal dissipation are the most important thing for the manufacturers and users. Referring to the relative international standard, TRS-1000 could conduct integration testing on optic, color, electricity and thermal, meanwhile record the changing curve of the parameters at real time.
