LED lamps lack authoritative standards, energy-saving lamps have become obsolete

LED lamps lack authoritative standards. Energy-saving lamps have become obsolete products. Energy-saving lamps that were once vigorously promoted have become obsolete products. LED lamps are currently the mainstream choice. So, in the minds of ordinary people, which incandescent lamp, energy-saving lamp, or LED lamp is the most cost-effective? Citizen Lao Li said that his family still uses incandescent lamps because the price is cheap, but it is getting harder and harder to buy. The newly renovated Ms. He said: “I think the effect and brightness of LED lights are definitely better, but in terms of power saving, I think it is not much different from energy-saving lights. The unit price of LED lights is obviously more expensive, so Comprehensive consideration of energy-saving lamps is not bad.' The reporter met Mr. Wang, a citizen who came to buy LED lamps in a lighting market in the urban area. He told reporters that energy-saving lamps had been used at home before, but he felt that the life of energy-saving lamps was relatively good. Short, it often breaks in less than a year, so I want to switch to LED lights. But Mr. Wang is a bit confused about which LED lamp to buy: “There are too many brands and I don’t know which one is good, and the price is also messy.” The reporter visited the market and found that there are many brands of LED lamps. The seller just said that they are from Guangdong. The goods purchased by manufacturers in other places are sold very well in the local area, and the quality is no problem. What is even more confusing for consumers is that the prices of LED lights on the market vary greatly. For example, they are all one-watt LED lights. Some merchants are quoting yuan, while others sell for yuan or even higher. LED lights are better at brightness and power saving, said Lao Li, an electrician from Pengcheng Decoration Company in the urban area: “Citizens often consider brightness when choosing lights. The brightness of LED lights is generally more than twice that of energy-saving lamps. Incandescent lamps In second place, energy-saving lamps are at the bottom. According to calculations, incandescent lamps consume kWh per hour; energy-saving lamps consume kWh per hour; LED lamps consume kWh per hour. 'Ordinary households usually turn on the light every day~a Hours, if calculated by ** lamp-on hours, RMB per kilowatt-hour, a W incandescent lamp costs RMB RMB a year, while a W energy-saving lamp costs RMB RMB a year. W LED lamps cost RMB 1. Annual electricity bill is RMB yuan. Obviously, it is not economical to use incandescent lamps. LED lamps are more expensive than energy-saving lamps, but the electricity bill is cheaper. There are many inferior lamps on the market. “There is a lot of knowledge about LED lamps, but individual businesses sell some inferior products to consumers while everyone is still not familiar with them.” The person in charge of Jinhua Mingchuang Optoelectronics Co., Ltd. told reporters that because the country has never With the introduction of relevant authoritative standards, the quality of LED household lamps on the market is also uneven. There are two types of light-emitting diodes for LED lights, one can be used for lighting, and the other can only be used as indicator lights. The LED lights that use the latter are sold very cheaply, but their luminosity is very easy to attenuate and will soon become dim. There is no doubt that LED lights will become the mainstream of the lighting market in the future, and now many manufacturers have seen its huge profit margins and have produced LED lights. But the problem is that there is no national authoritative standard. Most of these lamps are produced by enterprises' own standards, and their quality may not be as good as advertised. Consumers can easily fall into the trap of merchants because they do not understand the mystery. Although energy-saving lamps and LED lamps are generally about the same in terms of cost performance, it is best to use LED lamps for student desk lamps. Incandescent lamps emit light through the thermal effect of tungsten filaments. The working principle of energy-saving lamps is the same as that of fluorescent lamps. The heating filament emits electrons to collide with argon atoms and mercury atoms to emit ultraviolet rays, and then the ultraviolet rays excite the phosphor to emit light. Therefore, the light produced by the energy-saving lamp has stroboscopic light, and the energy-saving lamp with high frequency flash will also generate electromagnetic radiation, which can easily cause damage to children's eyes when used for a long time. The LED lamp uses the electronic effect of semiconductors to emit light, which is a low-voltage DC constant current source light-emitting device. Therefore, experts recommend that the student desk lamp use LED lighting.
