Due to the LED luminaries such as LED street luminaries developed, to do 4 geometry testing, it is hard to be hold in the traditional integrating sphere design. To solve this problem, Lisun design this new kind of sphere. 1. The hold base can bear max 20kg, it can expanding to test all lamps such as E27E40, all tubes such as T5T8T12, and all kinds of luminaries2. The hold base can be installed in the ceiling or down, it can be adjusted the height3. Hold base has four power cables connect to the outside Power Supply and max is 5KW4. The holder base is detachable. For some kinds of light sources you may need to change the position of the holder base.5. Diameter: IS-0.3M ( 0.3m), IS-0.5M ( 0.5m), IS-1.0MA ( 1.0m), IS-1.5MA ( 1.5m), IS-1.75MA ( 1.75m), IS-2.0MA ( 2.0m). Other sizes can be designed according to the customers request.6. The painting of integrating spheres is according to CIE Pub. No.84 (1989)We have different jigs for different kinds of light sources. For example, the following pictures show how to
