Description
According to the 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 requirement of IEC standards. LISUN designed the Constant Temperature
Integrating Sphere
(thermostatic sphere or temperature controlled integrating sphere) which keeps the temperature inside of the sphere stable at 25℃.
LISUN IS-*MT Constant Temperature Integrating Sphere is fully meet
IES LM-82
Clause 4.4.
Specification:
• Diameter: IS-1.5MT (1.5m), IS-1.75MT (Φ1.75m), IS-2.0MT (Φ2.0m). PS: Other big size can be designed according to the customer’s requirements.
• Painting material of integrating spheres is according to CIE .84 (1989)
• The internal 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%
