Our Complete range of products are Integrating Sphere With Holder Base, Constant Temperature Integrating Sphere, Integrating Sphere with Side Assistant Opening and New Design 3m Electric Integrating Sphere.

Integrating Sphere With Holder Base

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 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 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 4. 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 customer’s 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

Constant Temperature Integrating Sphere

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.

Integrating Sphere with Side Assistant Opening

  • Specifications Painting material of integrating spheres is according to CIE Pub.No.84(1989) • The painting material is BaSO4 coating:ρ(λ)≥0.96(450nm~800nm) and ρ(λ)≥0.92(380nm~450nm) Etc.

According to IES LM-79 Clause 9.1.2, it request the 4π geometry configuration and 2π geometry Integrating Sphere for the LED Testing. Lisun Group developed the integrating sphere with side assistant Opening in A Molding Technology to meet the requirements. The traditional integrating sphere is assembled by several pieces. Lisun Group developed A Molding Technology to produce the sphere. A Molding Integrating Sphere will be more round and the test results will be more accuracy than the traditional integrating sphere.
