LISUN IS-*MA Optical 4π Geometry Integrating Sphere With Holder Base is designed for this kind of LED luminaires. Due to the LED street luminaries developed, it is hard to do 4π geometry test in the traditional integrating sphere. Because there is no test base (platform) to hold so heavy LED outdoor lighting fixtures.
• Painting material of integrating spheres is according to CIE Pub.No.84 (1989) and IES-LM 79 Standard.
• The painting material is BaSO4 coating: ρ (λ) ≥0.96 (450nm~800nm) and ρ (λ) ≥0.92 (380nm~450nm)
• Fine diffuse reflection: Reflectance ρ≈0.8 and accuracy of ρ (λ) <1.5%
• Build-in all functional lamp testing jigs: for E40/E27, T5/T8/T12 tubes and the testing holder base for LED and other luminaires. All samples under test can be installed both up and down directions in the sphere.
• Power cable, power terminal and auxiliary lamp position are built-in (Auxiliary lamp is optional)
• Power cable and socket has been build-in. It is convenient to power on the lamp under test
• Two photo detector ports, one optical fiber port and temperature sensor hole are built-in
• Build-in cross laser can help to install the standard lamp and the lamp under test in the center of the integrating sphere
The integrating sphere works with a Spectroradiometer to do the photometry, colorimetry and radiometry parameters measurement.
• IS-0.3M/IS-0.5M is for LEDs, LED modules, mini LED bulbs & other small lamps. The flux testing range is 0.001 to 1,999 lm
• IS-1.0MA is for CFL or LED bulbs. The flux testing range is 0.1 to 199,990 lm
• IS-1.5MA/IS-1.75MA is for CFL, LED bulb and tube, fluorescent lamp, CCFL. The flux testing range is 0.1 to 1,999,900 lm
• IS-2.0MA is for HID lamps or high power lamps. The flux testing range is 0.1 to 1,999,900lm
Abstract: According to the particularity of LED luminous flux measurement, unique optimization is adopted in the design of the integrating sphere for LED measurement combined with the diffuse materials of high reflectivity, which makes the system stability and accuracy have great improvement. The experimental results show that the system stability and consistency is much higher than other commo...Release time: Apr, 132021 / Reading: 9 Learn more
