| LED ILLUMINATION UNIT |
| |
For solar cell or sensor testing sun simulators are often used as external sample illumination. The benefit of having a light source with a spectral power distribution close to the solar spectrum and with an absolute irradiance close to AM1.5 is decreased by the relatively short lifetime and the resulting high cost of ownership of the simulator lamps.
For all tests requiring a stable light source, but not necessarily a solar spectrum, Botest developed the LED Illumination Unit. The system is available as stand alone unit or as an integrated option for the LIV Functionality Test System. The LED Unit comprises a dedicated LED control unit and a specially designed cover with high brightness LED boards. LED boards with white or with RGBW LEDs are available. Special color temperatures for white LED boards are available upon request.
