The most critical factor that affects the quality of lighting is the luminous distribution performance of lamps. Using scientific testing methods and selecting the appropriate test instrument is the basis of obtaining accurate luminous distribution properties of luminaires. The test of luminaires’ luminous distribution is an important part of luminaire design and lighting design for […]
The CV model load is the basic of the LED power supply test. CV is constant voltage, but the load is only the current load equipment, itself does not provide constant voltage, therefore, the so-called CV is just through the voltage negative feedback circuit, to servo the change of LED power supply output current, to […]
During World War II and after the war, Western countries, especially the United States, have established a series of environmental testing ground, laboratory and developed environmental testing standards. Required by the US military, all weapons equipment, parts, materials, and ammunition must be sent to the environment laboratory to simulate environmental testing, and then sent to […]
UV aging test chamber is suitable for the aging test of non-metallic materials resistant to sunlight and artificial light. Light source adopts eight UV fluorescent lamps that rated power is 400W as a light source. UV fluorescent tubes are distributed on sides of chamber, every side has four (There are UVA-340 and UVB-313 light source […]
Xenon lamp aging test chamber adopts xenon arc lamp which can imitate the full spectrum sunlight to reappear destructive spectral wave in different environment. It can provide the corresponding environment simulation and accelerated test for scientific research, product development and quality control. It is also named “Sunlight Radiation Protection Test Device”. According to test standards […]
