It is understood that had vigorously promoted the CFL has become outdated products, current LED lamp is the mainstream choice. So, in the eyes of ordinary people, incandescent lamps, energy saving lamps, LED lamps which cost-effective? people Lee said, is he still using incandescent lamps, because they are inexpensive, but more and more difficult to buy. And the newly renovated Royal said: "I think better effects, brightness is definitely LED lights, but as for the province, so many I can't feel it and the difference in energy-saving lamps, LED lights on the purchase price is significantly more expensive, so consider energy saving lamp is good. ”
LED lamp WINS in terms of brightness and power-saving
City pengcheng decoration company electrician and Master Li said: "members of the public in selecting the lamp usually take into account the brightness problem, LED light brightness is generally higher than that of energy-saving lamps more than twice times, second in incandescent lamps, energy saving lamps is in last place. Through calculation, consumed 0.03652 kWh an hour incandescent bulbs are consumed 0.00814 kWh an hour; LED lights for one hour costs 0.00704 kWh. "Ordinary families usually light 5-6 hours a day if lights on 6 hours a day, 0.6 Yuan per kWh calculation, a 40W incandescent light bulb costs of electricity a year to 47.98 Yuan, and 10W CFL costs of electricity a year to 10.69 Yuan, 5W LED lamp costs of electricity a year to 9.25 Yuan. It is clear that using incandescent light bulbs are the least economic, LED light is expensive than CFLs, but electricity is cheaper.
LED lights brand price
The urban lighting market, the writer met Mr King to buy LED lamps for the public, he told reporters, before home with energy-saving light, but it feels like energy-saving lamp life is short, often broke in less than a year, so I want to switch to LED lights. But Mr King which LED lights a bit confused what to buy: "too many brands don't know what good, other prices. "The reporter visited the markets also found that, at present LED lights brand variety, the seller said it was from Guangdong and other manufacturers into goods, sold very well on the ground, the quality is no problem. Confuse consumers even more is that the LED lights on the market prices vary widely, such as both a 3-watt LED lamp, some merchant price is 10 Yuan, while others are sold for 50 dollars or even higher.
Bad lamps on the market
"So many LED lamps, solid knowledge, and individual businessmen while we still don't know much about, put some inferior products sold to consumers. "Jinhua company official told reporters, because the country has not issued the relevant authority standards, LED home lighting quality on the market today is also very different. There are two LED lights light emitting diode, lighting can do, another can only be led to use. Use LED lights which sold very cheap, but its brightness very easily decay and quickly darkens. LED lights of the future will no doubt become the mainstream market, many manufacturers now see its huge profit margins, have production of LED lamps. But the problem is that without the authority of the State standards, most of which are produced by enterprises to set our own standards, the quality may not be as good as publicity, consumers don't understand what's happened, it's easy to fall into the trap of businesses.
Although overall performance both CFL and LED lights, but table lamps LED lighting is best used. Incandescent lamp through thermal effects of tungsten light, the principle of energy-saving lamps and fluorescent lamps work the same way, by heating the filament emit electrons collide with argon and mercury atoms emit ultraviolet and ultraviolet excitation luminescence. So energy-saving lamps produce light flicker, energy-saving lamps also produce electromagnetic radiation of high frequency Flash, long lasting eye could easily lead to injury to the child. LED light use electronic effect of luminescence of semiconductor, is a low-voltage DC constant current source of light-emitting diodes, so experts advise students desk lamp with LED lighting.
