Method to test the stroboscopic LED dimming power supply

by:MOSO     2020-03-12
Now the use of electrical appliances and lamps and lanterns is very common, also is indispensable to life, with the rapid development of industry, the types of power supply is also more and more. LED dimming power supply is one of the, it is how to test the stroboscopic? LED dimming power supply test stroboscopic concrete method is as follows: what is a stroboscopic? Stroboscopic refers to the luminous flux and electric light source fluctuation, if the wave and the depth, the greater the means has serious stroboscopic, this kind of equipment the volatility of the depth and size of the technical scheme of electric light source has a direct relationship. Stroboscopic concrete is a kind of all kinds of lighting light source to the person eye stimulation, because people's eyes light stroboscopic perception is mainly depends on the frequency and amplitude of lighting source. General lighting source amplitude can through own brightness and the percentage of modulation to show. Experiments show that lighting light source frequency different can let the human eye can observe the stroboscopic of amplitude modulation to the relevant percentage is also different. If the frequency is low, the amplitude of scheduling requirements will be higher, even the smaller the amplitude of the scheduling will feel stroboscopic, but when the light frame frequency amounting to more than 50 hz is imperceptible to the stroboscope. After the test, the higher the brightness of the light source, its critical flicker frequency will increase, if the light source frequency is higher, stroboscopic is more difficult to detect. The traditional test method is to use black and white alternate with gyroscope rotation under the sunlight, then there will be a steady annular color ring pattern formation, and do not change with the speed of the rotation direction of rotation. Under the illumination of tested, turn the black and white alternate with of gyroscope, if gyroscope pattern change color or rings above, means that changes with the stroboscopic light, the more obvious that the more powerful strobes. How to avoid this kind of light stroboscopic cause damage to the human eye? Now the LED light can solve this problem, apply to the museum, jewelry exhibition purposes. Electrical focus on the LED light, 10 years experience in special lighting development, professional LED dimming power supply customized service.
