鈥⒙燭he painting of integrating spheres is according to CIE Pub.No.84 (1989)
鈥⒙燤aterial: Pure barium soleplate (BaSO4)
鈥⒙燘aSO4 coating: 蟻(位)鈮0.96 (450nm~800nm) and 蟻(位) 鈮0.92 (380nm~450nm)
鈥⒙燜ine diffuse reflection: Reflectance蟻鈮0.8 and accuracy of 蟻 (位) <1.5%
鈥⒙燘uild-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
鈥⒙燗uxiliary lamp position has been built-in. Auxiliary lamp and Auxiliary lamp device are optional
鈥⒙燩ower cable and socket has been build-in, it is convenient to power the testing lamp
鈥⒙燭wo photo detector ports, one optical fiber port and temperature sensor hole are built-in
鈥⒙燭he 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:
鈥⒙營S-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
鈥⒙營S-1.0M is for suitable CFL or LED bulbs. The flux testing range is 0.1 to 199,990 lm
鈥⒙營S-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
鈥⒙營S-2.0M is suitable for HID lamps or other high power lamps. The flux testing range is 0.1 to 1,999,900 lm

Due to the LED luminaries such as LED street luminaries developed, to do 4蟺 geometry testing, it is hard to be hold in the traditional聽integrating sphere聽design. To solve this problem, Lisun design a new kind of sphere.聽The new sphere order code is IS-*MA.

Integrating Spheres

1. The hold base can bear max 20kg, it can expanding to test all lamps such as E27/E40, all tubes such as T5/T8/T12, and all kinds of luminaries
2. The hold base can be installed in the ceiling or down, it can be adjusted the height
3. Hold base has four power cables connect to the outside Power Supply and max is 5KW

According to requirement of IEC standards, the standard test temperature is 25鈩, but high power lamps such as HID lamps and LED outdoor luminaries 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.
