LED Luminous Intensity Testing

Global ETS, LLC is now offering LED Luminous Intensity testing for all LEDs according to LED standard requirements of CIE 127-1997 A or B Condition.

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

• 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:
• 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
