Specification:
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, JDS200 could conduct integration testing on optic, color, electricity and thermal, meanwhile record the changing curve of the parameters with time.
• Thermal parameters:
1) Junction temperature, thermal resistance and K factor
2) Optical Parameters: Spectral power distribution, chromaticity coordinate, correlative color temperature, peak wavelength, dominant wavelength, semibreadth, red ratio, rendering index, luminous flux and optical power
3) Electrical parameters: Forward voltage(Vf) and forward current(If)
• Wavelength measurement range: 380~780nm; Thermal sink range: 5℃~90℃
• Wavelength preciseness:±0.5nm, Chromaticity coordinate accuracy: ±0.001 (Under standard illuminator A)
• Temperature control system accuracy: ±1℃, junction temperature accuracy: ±1℃
• Record the changing curve of parameters with time
• Programmable set thermal sink temperature, and If of LED for the purpose of imitating different working situation of LED
• Test condition complies with corresponding international standard
