(Summary description)　　When we use LED bracket lights, we should have a basic understanding of it, because most of the unqualified bracket lights on the market will flicker, so what is the reason for this flicker? Xiaobian analyzed it for you in the article. In addition, in the article, the editor also introduced how we should buy LED bracket lights, so that everyone can avoid choosing those products with substandard quality. If you are interested, please come and have a look in the article. !   Why does the LED stand light flicker?   1. The strobe of the LED bracket light means that the illuminance of the lamp is unstable following the frequency fluctuation, and the light changes in light and dark in a short period of time, and it feels like the light is flickering. The human eye will have a discernible threshold for this kind of light and dark change of the bracket light. Generally, the light flickering below 80Hz can be detected by the human eye. Higher than this frequency may be difficult for the human eye to detect, but the flicker of the bracket light still exists. 2. The LED bracket light is a diode and needs direct current. At this time, a driving power supply is required in the working circuit to complete the conversion of alternating current into direct current. If the quality of the driving power supply is not good, the internal components are relatively low-grade, and all the incoming AC power cannot be converted into DC power, resulting in unstable output current of the driving power supply. 3. In order to reduce the stroboscopic flicker of the LED bracket light, it is more necessary for the merchant to consciously improve the quality of the driving power supply, increase the capacity value of the rectifier filter capacitor, and reduce the occurrence of low-frequency ripple, which will cause a certain degree of cost in terms of cost. Some businesses that place great importance on their interests may not be willing to spend money to improve them. This also requires relevant state departments to pay attention and formulate standards and norms.   How to choose LED bracket lights?   1. When choosing LED bracket lights, metal halide lamps are used as the light source. The use time of this bracket lamp is ≥ 10000h, and the overall design of internal and external strong shock resistance is reasonable to solve the damage of bracket lights caused by obvious vibration, life reduction, support frame Cracked lamp problem. With electromagnetic compatibility, it is not easy to cause interference to the surrounding environment signals. The bracket lamp has good heat dissipation and can reduce the common failure rate. 2. Generally speaking, different colors of the bracket lights give people different feelings. Gentle, understated colors give a sense of tranquility, while highly saturated colors make it possible to see close-ups of objects clearly. The contrast of two different colors is used more in actual construction, which can better highlight the subject and improve the contrast.       　The above is the introduction of the relevant knowledge about LED bracket lights introduced by the editor.
