LED Luminous Intensity Distribution Tester

LS860 Luminous Intensity Distribution Measurement Meter 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.

Standard:
CIE 127-1997 “Measurement of LEDs”

Measurement:
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
