Luminous Intensity Distribution LED Lamp Tester LED Tester is a precise electronic instrument for measuring LED luminous intensity. It's strictly designed according to LED standard requirements of CIE 127-1997 A or B Condition.

Luminous Intensity Distribution LED Lamp Tester Measures:

Forward voltage(VF), Reverse Current(IR), Luminous Intensity(IV), Intensity Angle(2θ1/2), Misalignment Angle(Δθ), Equivalent Luminous Flux(ΦV) 

Specifications:

? Automatic mapping the spatial distribution of light intensity curve (at right angles and polar coordinates)
? Automatic determination of the beam angle: the common-angle and the intensity of 1/4 angle and intensity of 3/4 intensity angle
? Testing Angel range: -90°~+90°, Accuracy of angel: ±0.2°
? Spread Angle of light beam: θ(50%)θ(25%)θ(75%)
? Intensity range: 0mcd~30,000cd, Accuracy: 0.5%. Radiated power range: 1uw/cm2~999.9kuw/cm2,
? Built-in adjustable DC constant current power supply, output current up to 800mA
? Forward voltage (VF): 0.1V -- 20.00V Forward current (IF): 0.1mA -- 800.00mA
? Reversed current (IR): 0.01μA -- 200.0μA Reversed voltage (VR): 0.1V -- 20.0V
