LED luminous Intensity-angle Distribution Test System 1 constant current source Interior (0-1500mA can be extended), LCD display

Advantage: avoid the systemic error effectively and improve the precision

2 To measure luminous intensity view angle curve, maximum light intensity0300cd , zero position light intensity and light intensity deviation angle θ and spread angle25%θ50%θ75%θand other electrical parameter automatically

3 Ir luminous intensity testing can be extended

4 These systems comply with CIE standard.To provide I-Iv, I-Vf, θ-Iv curve analysis for your R&D stuff
