The table lamps are our good helper whether at work or study in daily life,. As LED technology improves and prices decrease , LED also come into play on table lamps .
Although the light efficiency of the LED light is higher than the traditional lighting products, but consumers can not arbitrarily choose LED lamps. Some medical experts pointed out that many LED lamps having a serious blue overflow will cause irreversible damage to the retina of children . Electric light experts have recommended that the current national recommended standards should change into mandatory , suggested that government departments carry out special risk monitoring for indoor LED lighting products .

Yu Anqi,deputy director of the Shanghai National Electric Light Source Quality Supervision and Inspection Center, the blue light as the kind of shade commonly found in a variety of lighting , whichis inevitable, but most LED lamps emits blue light through the chip on the market today , which excite the yellow fluorescence to reconcile into a white powder , once poor control,the problem is particularly prominent.

There are technical staff of the electric light industry pointed out , too much blue for indoor lighting , will make a series of effects on people ‘s physical, psychological, such as the optic nerve . Currently, there are luminescent diffusers spraying technology used to secondarily pack for LED lamps ,its bio- safety index is lower than conventional LED lamps light. The person in charge of this technology , Shanghai Xiang Ling Optoelectronics Technology Development Co., Ltd. Chairman Deng Yaqin introduced their export products in the EU test, blue overflow value is only one-fifth of the standard . But Yu Anqi reminder , LED lamps are not suitable for student lamp, best or incandescent lamps.

Yu Anqi thought the dangerous blue relate to human health , he suggested that the current national recommended standards should change into mandatory and include the lighting level CCC standard, suggested that government departments carry out special risk monitoring for indoor LED lighting products.

Of course, consumers must not freeloaders simply consider the price when purchasing the lighting products, good quality is an integral part of the important factor of the lighting products , we have to remind the user to choose a brand and quality assurance of products in order to get good lighting experience.

UVTOP device packaged by the SMD produced by the American Sensor Electronic Technology Company SETi has completed product qualification, and its first product has shipped from the production line.

http://www.lead-lighting.com/products/bid32-1.htmThis establishment of the milestone precisely SETi results of the company’s growth of the first phase, this growth plan stems from October 2011, SETi companies have invested $ 20 million for new production equipment and expand its Advanced Technology Center. to the first batch of LED provided by new production line is the UVC LED used to disinfect utensils, the wavelength is 275nm, which provide the consumer market with the sterilization UVC LED.

The price of mainstream disinfection market is very sensitive, but SETi said they have repriced the standard SMD UV LED which compete with the traditional light and has been produced on the new production line. “The new production equipment allows SETi to focus part of the business on the manufacturing, so can increase productivity through operating methods to reduce costs,” Dr. Remis Gaska, President and CEO, said, “we directly help our customers save the cost, thereby increasing new market opportunities, “he added. As a standard SMD products, the price of UVC LED is basically the same as that of the traditional white LED flat, making the new product have the opportunity to make use of the advantages of UV LED to enter the new consumer markets, according to SETi estimates.

“Over the past few years, we have been working with manufacturers of consumer products to maintain cooperation, and we will use the UV LED to sterilize the water and air at our own home soon, so that to keep our food fresh and longer.” Gaska said.

Other wavelengths of UV LED is waiting for accreditation on the SETi high volume production line, the wavelength of 310nm LED is expected to be launched in the fourth quarter of 2013.

The United States has made the more leading position of the LED technology ,using the with LED to disinfect makes our lives more healthy and safe, what can be said that LED as the semiconductor-based lighting is in addition to linked with the field of science and technology and biotechnology , but also perfectly combine with the fashion design , medicine, agriculture, aerospace and more walks and bring us unexpected visual experience and convenience, of course, under the premise of increasing demand on the energy saving over the world , and now LED lighting outstanding advantages in energy saving, most of the LED is used for general lighting.Meanwhile,there are a large number of manufacturers specializing in developing and producing LED light, lead lighting is one of them,Lead lighting has been continuing to strengthen the use of certified raw materials such as LED chips, LED drivers, heat sinks, shell, etc., and improve R & D and production team, striving to adopt the best materials and technology to produce best quality LED flood light, LED tunnel light, LED tube light and other indoor and outdoor lighting, using highly integrated high-brightness COB as the light source of the LED Flood light and LED tunnel light and other outdoor lighting,adopting high brightness SMD LED as the light source of the LED tube light, the low-voltage constant current driver ensure the alternating current can be convert into direct current so that improve the energy use and reduces the stroboscopic effect stimulating the human eye, fully guarantee octahedron illuminated area of LED flood lights and bright light to adapt to outdoor open environment ,the soft and bright light of the LED tunnel light and LED tube light makes us safe driving in tunnels and enjoy work and study.As an ISO 9001:2000-certified factory,the lead lighting can meet the strict standards of CE, RoHS, FCC certificate, these strict producing standards guarantee our products distribute smoothly both in domestic and international markets. visit http://www.ledclan.com to Learn more vivid and specific characteristics of the LED tube light or click http://www.lead-lighting.com/products/bid32-1.htm for more detailed and professional features and uses of the LED tunnel light or return homepage to take a good look at other LED light.

With the acceleration of urban construction, more and more mountain are connected by the tunnel , we have been concerned about how to choose a good tunnel lighting, as the tunnel is semi-closed environment, we must choose the lamp which can properly light up the tunnel and come through the fog and have the features of the strong waterproof and rustproof ,the high-pressure sodium lamps is currently the most widely used, but with increasing demands on energy saving, plus that the light colour of the high pressure sodium and mercury lamp is narrow, the brightness is low, we begin to turn to LED tunnel lights, so, what is the difference between the LED tunnel lights and high pressure sodium in the end?

1, just from the luminous efficiency, the LED tunnel light is 90lm / w,the sodium light reach 120lm / w;

2, from the performance of through the fog, the golden yellow light of the sodium light can better through the fog, of course, which can also be replaced with warm white LED tunnel light;

3, in view of the initial investment cost, the price of the LED tunnel light is three to four times more than the sodium light;

4, as far as the saving the cost is concerned, taking into account the factors such as the power , LED lights can save more than 60 percent;

5, long life, LED tunnel lights can theoretically reach 50,000 hours or more, but limited by a variety of factors, such as lamps heat dissipation, the life of the power and so on, the life of the sodium lamp can reach 12,000 hours, considering the high cost of maintenance in the tunnel, the LED tunnel lighting is more appropriate;

Generally speaking, 100W LED lighting can completely replace 200W high pressure sodium (the specification of the sodium light is typically 250W), but we should choose the right products from the color temperature, light efficiency, heat dissipation, etc., in addition to a large number of products must be used for the project, we can make a relatively detailed investment plan to contrast,after the initial investment of the product, energy-saving performance and maintenance costs are analyzed. LED tunnel lights is better than the high sodium sodium light.
