According to requirement of IEC standards, the standard test temperature is 25°C, 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.Constant Temperature Integrateing Sphere Measurement System Specifications:• Diameter: IS-0.3M (φ0.3m),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). Other size can be designed according to the customer’s request.• 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: The vertical is for E40, E27 and so on. The horizontal is for T5/T8/T12 tubes. 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°C-55°C (refer to the environmental temperature with 25°C).A. Temperature Increasing tolerance: ±1°CB. Temperature Down tolerance: ±2°C Applications:The integrating sphere works with a Spectrophotometer 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.• IS-1.0M is suitable for CFL or LED bulbs. The flux testing range is 0.1 to 199,990 lm.• IS-1.5M/IS-1.75M is suitable for CFL, LED bulb and tube, fluorescent lamp, CCFL. The flux testing range is 0.1 to 1,999,900 lm.• IS-2.0M is suitabe for HID lamps or other high power lamps. The flux testing range is 0.1 to 1,999,900 lm.
