Eight hours a day, electricity costs $three a piece of electricity so five LED lights can not buy

A few days ago, a television gaffer said, now a kind of energy-saving lamp energy-saving LED lamp more than many on the market, he is ready to replace the LED mom downlight lamp.

"Even if the LED lamp is open 24 hours a month, as long as the money piece of electricity, so the elderly urinate at night safer. "

In addition, in the next five years, LED output value of up to $20 billion, has been listed as one of the top ten strategic emerging industries in Hangzhou.

What exactly is this LED lamp? Is it really that electricity? Can you change the energy saving lamp into LED lamp?

Turn on the lights 10 hours a day

LED lights can be used for 13 years

LED full name is Light Emitting Diode, is a semiconductor light-emitting diode, can be directly converted into visible light energy, more efficient than energy-saving lamps, so more energy efficient, more environmentally friendly.

LDE lights, the last century in 60s has been, the only out of red, and later with green light, mainly used in the dashboard and decoration. Now widely used in mobile phones, computers and cars.

In early 90s, foreign research issued a high brightness LED Blu ray, so that the LED has been able to mix other colors of the three primary colors - red, green, blue, into the home lighting possible. Professor Huang Jingyun, Professor of materials science at Zhejiang University.

Than the brightness, 1 watt LED lamp brightness is equivalent to about 2 watts of energy-saving lamps, and the power of the 90% converted into visible light, less heat;

Than the energy saving, 5 Watt LED lamp power consumption of 5 degrees, 1000 degrees, the same lighting brightness, the energy consumption of 10 watt lamp for 1000 hours power consumption of 10 degrees;

Than life, service life of energy-saving lamp for 8000 hours, LED lamp can reach 50 thousand hours -- equivalent to open 10 hours a day, for 13 years, no LED lamp filament, don't worry about breaking the bulb;

More than environmental protection, including energy-saving lamps, including ordinary lights contain mercury, dozens of light bulbs containing mercury can pollute the whole of West Lake, and LED lights are not;

Than health, energy-saving lamps will produce ultraviolet light and infrared light, while the LED lamp without radiation.

LED lamp home varieties are still rare

At present it is not worthwhile to use

LED lights a lot of benefits, but now it is difficult to buy home LED lights on the market. Home LED lamps are mostly used as auxiliary light and decorative spotlights and lights, and the main lamp, table lamp simply do not have to buy.

"A household LED lights in three hundred or four hundred dollars or so, a few hours a day, it is not worthwhile. "Hangzhou Jing Li lighting appliance company mister Sun Jian, is a well-known German lighting company OSRAM agents. He said that the current LED core technology in Germany, OSRAM, Holland, PHILPS and other five international lighting giant hands, LED lamp manufacturing standards to be developed by them, but has not been introduced. There is no standard, the market certainly chaos. 1 watt LED lights, high-end product prices should be around $100, but now from the twenty or thirty to the 100 block, a lot of LED lights are low-end products produced in china. "

Sun Jian said that the current LED lamps are used most of the shopping malls, office buildings, hotels, factories, high-end real estate, in addition to the museum, art museum, because the LED lights will not cause damage to the collection.

Zhejiang Ji Laitai Photoelectric Technology Co. Ltd. is a manufacturer of LED lamps in local Hangzhou, manager Hong Wei did not suggest that the family use LED lights, "in fact, all kinds of LED lamps of home now can produce, the main problem is not production or price. If you are not a long time, a lot of use, then all of the home lighting LED light is not worthwhile, which is the market for home LED light very few reasons. "

Currently on the market more common household LED spotlights, 2 watts equivalent to the equivalent of 20 watts of ordinary light, the following is a comparative account:

2 Watt High Quality LED spot light for 20 watts

Price 200 yuan about 20 yuan

Lighting time 8 hours / day 8 hours / day

Peak price of about 0.6 yuan / degree of about 0.6 yuan / degree

Annual electricity costs about 3.5 yuan about $35

The total cost of 203.5 yuan to 55 yuan

"If for the safety of the elderly in the toilet, can change LED lamp as the light, the light is best not to tell them the price. Sun Jian said.
