Integrating Sphere IS-100MT
According to requirement of IEC standards, the standard test temperature is 25℃, but high power lamps such as HID lamps and LED outdoor luminaires will produce a lot of heat during the test, thus the temperature inside the integrating sphere can not meet the requirements of IEC standards. Lisun Group designed the Constant Temperatured Integrating Sphere which allows the lamp was tested in a constant air temperature.
Specification:
• Diameter: IS-1,0M (φ1,0m)
other sizes available: IS-0.5M (φ0.5m)、IS-1.0M (φ1.0m)、IS-1.5M (φ1.5m)、IS-1.75M (φ1.75m)、IS-2.0M (φ2.0m).
• The painting of integrating spheres is according to CIE Pub.No.84(1989)
• Material: Pure barium soleplate (BaSO4)
• BaSO4 coating: ρ(λ)≥0.96(450nm~800nm) and ρ(λ)≥0.92(380nm~450nm)
• Fine diffuse reflection: Reflectanceρ≈0.8 and accuracy of ρ(λ)<1.5%
• Build-in lighting holder position: E27 . The side assistant opening is for lighting fixtures
• Auxiliary lamp position has been built-in. Auxiliary lamp and Auxiliary lamp device are optional
• Power cable and socket has been build-in, it is convenient to power the testing lamp
• Two photo detector ports, one optical fiber port and temperature sensor hole are built-in
• Constant Temperature controlled range: 25℃-55℃ (refer to the environmental temperature with 25℃).
A. Temperature Increasing tolerance: ±1℃
B. Temperature Down tolerance: ±2℃
• The traditional integrating sphere is assembled by several pieces, Lisun Group developed A Molding Technology to produce the integrating sphere. A molding integrating sphere will be more round and the test results will be more accurate than the traditional integrating sphere
Integrating sphere theory and Applications:
The integrating sphere works with a Spectroradiometer to do the photometry, colorimetry and radiometry parameters measurement:
IS-0.3M/IS-0.5M is suitable for LEDs, LED modules, High Power LED, mini bulbs and other small lamps.
The flux testing range is 0.001 to 1,999 lm
Due to the LED luminaries such as LED street luminaries developed, to do 4π geometry testing, it is hard to be hold in the traditional integrating sphere design. To solve this problem, Lisun design a new kind of sphere. The new sphere order code is IS-*MA.
