Chinese market is so new just came out, as long as the good sales, high customer focus, may be overnight, major markets throughout the country. Many manufacturers sinister, low material, same product can make different versions of specifications, say lamp beads, power, aluminum shell thickness and material (industrial scrap).
Take 3 * 1W high power Ceiling detail explanation:
Lamp beads: 3 * 1W meant to say, is composed of three 1W lamp beads, plus power, real power over 3W.
Now there are three common market 0.5W combination, a combination of three 0.75W, three 1W combination.
Power: Power is the key to see the current, whether constant current, belt wear protective current driver IC.
3 * 0.5W current general 150MA - 170MA around
3 * 0.75W current general 180MA - 220MA around
3 * 1W current general 300MA - 350MA around
Aluminum housing: the key to a surface treatment, reflective more delicate appearance, the higher the aluminum content, the higher the content of the coarse impurities.
Aluminum thicker the higher the price, the common 1.5MM 2.0MM 2.5MM 3.0MM
Manufacturers are generally black heart with a combination of 3 * 0.5W of power with cheap, inferior race thick aluminum to a good red, LED applications is a hot industry, but also to support the government's new energy-saving and environmental protection industries, but why is the black heart of our China factory with defective to reap huge profits.
Alert LED glare harm to human body
In recent years, the development of LED lighting presents a bustling scene. Like other artificial light, LED light radiation can theoretically cause little harm to humans. Injury occurs mainly in people's eyes and skin, such as skin and eye photochemical harm, harm the eye near ultraviolet, blue photochemical retinal hazard, aphakic photochemical retinal hazard retinal thermal hazards of skin and heat hazards, and both among the more vulnerable eyes. In addition, LED glare can also cause harm. Glare is on the horizon due to the distribution of brightness or scope inappropriate, or in space or time of the existence of extreme brightness and contrast, as well as cause discomfort and reduce the visibility of objects visual conditions, glare lighting quality evaluation is one of the most important factors .
Following the radiation hazard has been listed as "air, water, noise" outside the fourth largest environmental security issues facing mankind World Health Organization. Optical radiation is an important part of the radiation, its ultraviolet radiation and blue light radiation on the human body, especially significant. In recent years, with the development of LED technology and market requirements, radiance LED chip greatly improved, more and more narrow beam, plus part of manufacturers and excessive application of UV LED chip, blue band, so that the LED light radiation hazards become a problem can not be ignored. LED light radiation hazards mainly reflected in the near-ultraviolet radiation damage of the eye, retinal photochemical damage and Blu-ray radiation of heat damage.
Reporters from the experts responsible for optoelectronic inspection officer that "light biosecurity" unqualified person may lamps shine injury, also may hurt people's eyes. Especially the excessive use of blue or ultraviolet light emitting LED lights, more prone to leakage of blue or UV light bodily injury problems. Currently the EU has mandated LED lamp light biological safety testing, the experts called the country also should pay attention to.
In theory, the use of the type of lamps, LED lamps on people's health (not just of the eyes) minimal damage, or even that did not hurt. Of course, the premise is a must use regular brand manufacturers qualified by domestic or foreign CCC certification UL, CE and other types of security, electrical certification of LED lights. If you use poor quality LED lights, it is better not.
Inferior LED lights blue light hazard
Safety light environment once again sparked concern: on the one hand of a sharp rise in incidence of juvenile myopia; on the other hand home lighting, work according to the outdoor lighting is that even adults are eye health hazard. Lighting is not the brighter the better? How light environment was conducive to eye health? Experts point out that parents, teachers and the light source manufacturer, has a responsibility to popularize scientific knowledge consumption light source should be used in favor of the health of students and lighting no radiation, no flicker of energy saving lamps.
Users in the purchase of LED indoor lights, not only the lamp power, because the LED lamps are not the brighter the better.
Phenomenon 1: LED lamp price level of refractory
Expert: Mo buy less than $ 20 5W bulb
It is reported that consumers in the market to buy LED lamps indoor lights, we often see a puzzling phenomenon: a well-known brand 4W LED bulb price of 40 yuan, and some unknown brand of 5W LED Bulb but only sell 20 yuan a. Both bulb, in the end of the election Which bulb do? Many consumers told reporters that they tend to choose a more bright LED bulb.
It is understood that because of the color temperature, the higher the luminous efficiency, LED interior lights look more bright. However, in actual use, low color temperature looks more comfortable, the corresponding cost would be high. Ethernet sunlight, for example, in the morning and evening sun, the color temperature between 3000K ~ 3500K, softer look, at noon, the sun rises to 4000K color temperature to 4500K, it has been more glaring. Incandescent and fluorescent color temperature of 6200K has reached bottom.
Reporters learned that regular domestic manufacturers will be marked on the packaging bulb color temperature, color temperature commonly used is 2700k, namely ordinary incandescent color temperature, which is characterized by a warm feeling of light, but bright enough, for the bedroom nightstand, wall, etc. local lighting; 3000k color temperature is closest to the natural light, is a warm light, the light is both warm and bright, the overall lighting design is suitable for home; 5000k is white above, is a cool light, can make people concentrate, suitable for office, study, and other places use.
Experts: At present, in the lighting market, general household Indoor LED lamp power between 3W ~ 7W, 5W bulb about market prices generally at 50 yuan, if less than $ 20, then the LED indoor lights quality is certainly a problem, not only can not protect eyesight, but also greatly shorten the life of the light source. In addition, consumers in the purchase of LED indoor lights, not only the lamp power, because LED lighting is not the brighter the better.
Phenomenon 2: inferior LED lights blue light hazard
Expert: Mo cheap, buy big brands
Then LED lights from incandescent to energy-saving lamps. In recent years, energy-saving lighting products for social attention than ever before. In this regard, some of the medical profession and the electric light source experts have pointed out, there are serious blue overflow lot LED lamps, over time people will suffer irreversible retinal damage.
LED lamps have a visual impairment it really Lighting Research Institute of Fudan University, deputy director of Shan-end associate professor, told reporters:? "The principle of white LED is a blue LED chip white light after excitation yellow phosphor conversion of blue light hazard refers to the formation of the light source. 400 to 500 nm and blue bands if the brightness is too high, it may cause retinal photochemical damage after a long look into the eyes light. blue hazard depends Blu-ray dose received by the human eye in the light of the accumulation. "
"If you purchased a qualifying fixtures and used properly, LED lights are not more dangerous than traditional lamps." Insiders pointed out that, at present, the domestic LED lighting manufacturers have been more than 3,000 light our national standard "lamps and lamp systems biological safety ", the blue light hazard calculation method and quantization to make clear that, noting that LED lighting products, compared with other sources and there is no difference, within the scope of the safety limit of radiation exposure requirements.
Experts: Optical Engineering, Zhejiang University, Professor Mou with the rise, said the international community in accordance with the intensity of the blue light has been developed biosafety standards related to the Blu-ray and Blu-ray may harm the set value. For example, there will be no harmful blue light source product called "zero-products"; hazard will have a smaller blue eyes can not look directly at the light source product for a long time referred to as "a class of products"; there will be a greater source called blue light hazard "second-class products." LED lighting is currently used as a class and a class of substantially zero, if it is obligatory II were marked "the eye can not stare." Therefore, in the purchase of LED lamps, not freeloaders, to choose a big brand products.
Phenomenon 3: Eye of varying quality
Expert: china Optional 3C signs to look for
Lamps adults and children to learn, an indispensable tool for work. To prevent myopia, a good choice for children Eye, a problem many parents consider. According to the reporter, currently on the market Eye dazzling array of products, many products are advertised themselves as "no flash", or high-tech LED lights, and the price is much higher than ordinary lamps. What do these lights can not protect the child's eyes?
Reporters visited the Guangzhou city Carrefour, Trust-Mart supermarket, several lamp area to see Chin lamp products, half for children "Eye." Prices of these products varies, the same lamp, table lamp with the word "eye" and other, relatively speaking, a few hundred dollars more expensive than ordinary table lamp. Some LED's "Eye", the price is much higher than more.
Reporter observed, put on the shelf lamp, lamp did not indicate "eye" feature, ranging in price from 80 yuan to 300 yuan; and marked "eye" feature lamps, the cheapest to $ 300, expensive even 900 yuan. Reporters also found that, in addition to the difference in the price, a lot of "Eye" products are not related to the "3C" certification mark.
Experts say: "Eye" is currently mostly marketing concept, whether there is "eye" effect is not OK, consumers in the purchase process, we should pay attention to see the security certificate with the description, choose the best after-sales service products, and Note that the product 3C certification mark.
Warm Tips
Children's room light design coup
The study found that long-term use "full bright" light is one of the factors leading to high incidence of myopia of our young people. If the lamp brightness is much higher than the general brightness of the indoor environment, people will feel dizzy. Visible brightness large light fixture does not mean good, too bright will damage the retina. How can we let our children live in a relatively safe light environment experts to look at the safety measures?:
1 different designs in different regions.
Children's room both games, learning, sleep and other functions, different functional areas, lighting requirements are different; the light intensity and area of the playing field can be slightly larger. Light intensity learning zone may moderate some of the focus. Sleeping area to try to soft light, warm, which helps the child to feel safe, to help sleep.
2 avoid uneven illumination.
A too bright and too dark in other parts, it is not balanced design. Therefore, in addition to the main light source, you can set up some type of auxiliary light source (such as wall lamps, floor lamps, table lamps, etc.), the intensity of light through different spatial position, angle to reconcile the difference between indoor light, in order to ease the eyes of a child fatigue and discomfort.
3 up to the reflected light.
If you want to use the indirect reflected light as ambient light, pay attention to make up the reflected light shade as much as possible, not reflecting downward. Because the reflected light downward direct light may make the child's eyes, can damage the child's vision.
4 caution Spotlight
If lighting is not good, it will cause the child mental stress. If you want to use spotlights illuminated wall art (such as frame), to avoid the glare of highlights. So, playing light when fired from the side of art, the light from the side, the glare of the bright spots will not be reflected directly to the human eye.
5 Select adjustable lighting
The best choice can adjust the brightness, angle of lighting, the light dimmed some of the night, increase the child's sense of security, to help children fall asleep as soon as possible. After the kids go to sleep, be sure to turn off the lights. Because the children sleep in the light, vision is impaired, a much higher rate of myopia than children to sleep in the dark.
LED industry to solve the problem of light pollution in action
In the LED is recognized as the best source of future time, the industry has frequently broke the poor quality LED light pollution problems. As a new light source, LED lighting technology and applications in recent years have made rapid development. At the same time, LED light source on human health security has been more and more attention. LED lighting as a healthy carrier will be more widely applied to our lives, then the use of different occasions, how to determine the safety of LED? For health LED lighting, is there a quantitative standard? How healthy lighting results of research and development combined with the market really, and guide enterprises to develop more scientific safe and healthy LED lighting products? this ponder the problems caused by the industry
Lamp beads: 3 * 1W meant to say, is composed of three 1W lamp beads, plus power, real power over 3W.
