LED light is difficult for people to choose the market chaos why?

Jinhua news network, it is understood that once vigorously promote energy-saving lamps have become obsolete products, the current LED lamp is the mainstream choice. So, in the minds of ordinary people, incandescent lamps, energy-saving lamps, LED lamps which is the most cost-effective? Lao Li said that his family is still using incandescent lamp, because the price is cheap, but more and more difficult to buy. The newly renovated and Ms. He said: "I think the effect is certainly better, brightness LED lamp, but the power, I think it is not too much and energy-saving lamps, LED lamps on the purchase price was more expensive, so considering the energy saving lamp is also good. "

LED lights in brightness and power saving

City Pengcheng decoration company electrician Lee said: "people in the choice of lamps often will also take into account the brightness of the LED lamp, the brightness is generally higher than the energy-saving lamps more than two times, ranking second incandescent lamp energy saving lamp, the bottom. Through the calculation, the incandescent lamp consumes 0.03652 kwh an hour; energy saving lamp is an hour to spend at least 0.00814 kwh; LED light consumes an hour of 0.00704 kwh. "The ordinary family in general every day on 5~6 hours, if calculated at day lights 6 hours, 0.6 yuan per kWh, a 40W incandescent lamp to take electricity 47.98 yuan a year, while the energy-saving lamp 10W a year to spend 10.69 yuan electricity, LED lamp 5W takes charge of electricity 9.25 yuan a year. It is clear that the use of incandescent lamps is the most economical, LED lamps are more expensive than energy saving lamps, but they are cheaper.

LED light brand price chaos

I had to buy the LED lamp of Mr. Wang of the public in the city a lamp on the market, he told reporters, before the family has been using energy-saving lamps, energy saving lamps but feel relatively short life, often less than a year on the bad, so I want to change into LED light. But Mr. Wang in the end what kind of LED lights to buy a little confused: too many brands do not know what kind of good, in addition to the price chaos. Reporters visited the market also found that the current LED lamp brand variety, the seller just said that this is from Guangdong and other places into the factory goods, sold well in the local, quality is no problem. Even more confusing for consumers, the market price of LED lights vary widely, for example, the same is a 3 Watt LED lights, some merchants offer is $10, while others sell to 50 yuan or even higher.

Poor quality lamps on the market

LED lamp of knowledge is very much, while the individual businesses are taking advantage of the current we do not quite understand, some inferior products sold to consumers. Jinhua, a person in charge of the company told reporters, because the country has not issued the relevant authoritative standards, and now the market is not the quality of the domestic lighting LED. There are two kinds of LED light emitting diodes, one is to do with lighting, and the other can only do with the lights. The latter uses the LED lamp to sell very cheap, but its luminosity is very easy to decay and will soon become dark. There is no doubt that the future of LED lamps will become the mainstream of the lighting market, and now many manufacturers have seen its huge profit margins, have produced LED lights. But the problem is because there is no national standard, these lamps are mostly manufacturers since the standards, the quality may not be as good as propaganda, because consumers do not understand the intricacies, it's easy to fall into the trap of businesses.

Although the energy saving lamps and LED lamps, the overall price is almost the same, but the best use of student lamp LED lamp lighting. The incandescent lamp is the thermal effect of tungsten light, work principle and energy saving fluorescent lamp as the ultraviolet, emitted by heating the filament emission electron collisional argon atoms and mercury atoms, then UV excited phosphor. Therefore, the light generated by the energy saving lamp, high frequency flash energy saving lamp will produce electromagnetic radiation, long-term use of the child's eyes easily cause damage. The LED lamp is the use of semiconductor electronic effect of light, is a low voltage DC constant current source of light-emitting devices, so experts recommend that students use LED lamp lighting table lamp.
