(Summary description) 　　Unlike incandescent and fluorescent lamps, LED lamps are not as bright as incandescent and fluorescent lamps, and LED lamps are prone to light decay. Why do LED lamps have the phenomenon of light decay? This is related to many factors, such as the chip quality and brightness of LED lamps and so on. So, how can we extend the service life of LED lamps?     　　Lamps should use good aluminum to ensure heat dissipation. At present, a large number of plastic and glass LED lamps on the market have serious insufficient heat dissipation and short lifespan. There is a defect in the production process, and the heat dissipation of the LED chip cannot be exported from the PIN pin well, resulting in the high temperature of the LED chip and aggravated chip attenuation. Due to the use conditions, the LED is driven by constant current, and some LED lights are driven by voltage, which makes the LED decay too fast. The drive current is greater than the rated drive condition. In fact, there are many reasons for the light failure of LED products, but the most critical is the heat dissipation problem. The better the heat dissipation performance, the lower the LED operating temperature, the smaller the light decay, and the longer the LED life.     　　In fact, the light decay of lamps is a necessary process in the work of lamps. When selecting lamps, we should try to choose lamps with better quality and heat dissipation performance. During use, we should also try to reduce the workload of lamps in order to delay the speed of light decay. , prolong the life of lamps. Whether to deal with light decay varies from place to place. First of all, look at the demand for illuminance. If it is an office area, the illuminance of the work surface may really need 300lx. If it does not meet the standard, it will bring discomfort such as easy fatigue. Therefore, places with illumination requirements, such as offices, museums, and gymnasiums, are required to meet strict illumination standards, and the LED light source has a relatively long lifespan. At the beginning of the design, it is necessary to leave a margin.     　　But for a hotel, is there really a difference between 300lx and 200lx? In fact, there is no difference, because at that time, the illuminance is not important anymore. What is more important is whether the distribution of the illuminance conforms to the purpose of creating the atmosphere and the scene, as well as the control of glare. In hotel applications, we are more concerned about the feeling of people walking in. In fact, there is not much difference in the construction of the entire light environment and the specific illuminance, because people's visual perception is very flexible.   　　For some special occasions, such as the illumination of a salon venue, the highest place is more than 1000lx, and the darkest place is 10lx, which is not very comfortable, and the contrast between light and dark is quite atmospheric, the hotel needs this effect, so for the hotel In other words, the illuminance is not so important, that is to say, the light decay in a certain range is not so important. Depends on the occasion and requirements of use. If the decorative effect is used, it only needs to have colorful colors, such as red, green, blue and other LED tubes, and there is no need to consider the problem of light decay, only the color effect. There are only two issues to consider at this time. The first is safety and reliability, try to improve reliability, there should be no damage in the middle, so as not to affect the overall decorative effect, the second is waterproof, if it is used outdoors, the waterproof level should be at least between IP65-IP68, otherwise don't. Put it outdoors. If the water leaks, the direct result is damage, and it is easy to leak electricity if it is not handled properly. At this time, safety and reliability have become our main consideration.
