Incandescent lamp, LED lighting the lack of national standard into hidden dangers

　　In accordance with the phase out incandescent roadmap, issued by the state to the next year, on October 1, our country will be a total ban on sales and import more than 15 watts and general lighting incandescent lamp.According to observation, incandescent lamp has basic exit the market, and had promoted energy-saving lamps and phased out, LED lighting has become the mainstream market.But due to the lack of relevant national standard LED lights products prices confusion, quality the good and bad are intermingled of problems emerge in endlessly.

　　Energy-saving light phase out leds into the mainstream

　　Recently, who lives in precision.our area fountain lake street community Fang Mingkang because home sitting room lamps and lanterns is serious aging, plans to change new lamps and lanterns."Now I am home is energy-saving lamps, yesterday I went to the market of lamps and lanterns to turn a circle, energy-saving lamps have seldom found market."Fang Mingkang finally bought a LED lights.

　　On September 7th in the afternoon, the reporter comes to building materials market of zhejiang, the lamps and lanterns shop have LED lighting sales.Zhao Huasheng introduced a light shop owner: "now buy less energy-efficient light bulbs, when decorating bridal chamber a lot of young people will buy LED lights."

　　"Energy-saving lamps more than twice higher than that of the brightness of the LED lights."In recent years, LED lights in market demand, Zhao Huasheng explanation, though LED lights price is slightly higher than that of energy-saving lamps, but energy-saving lamps produce stroboscopic light, high frequency energy-saving lamps will produce electromagnetic radiation, the use is easy to cause damage to the eyes for a long time, "and LED lighting using semiconductor light-emitting electronic effect, is a low voltage dc constant current source of light-emitting devices."

　　"LED performance, safety and other aspects are better than energy-saving lamps, combined with the energy-saving lamps are affected by mercury pollution that one can't avoid factors, is a matter of time before it replaced. LED material mainly silicon, no environmental problems."Zhao Huasheng said.

　　Zhao Huasheng calculated brushstroke zhang: a 40 w bulb cost 0.03652 KWH per hour, a 10 w energy-saving lamp cost 0.00814 KWH per hour, a 5 w LED lights cost 0.00704 KWH per hour."Assuming that ordinary families to turn on the light 6 hours a day, 0.6 yuan per KWH calculation, with a 40 w bulb electricity is 47.98 yuan a year, with a 10 w energy-saving lamps electricity is 10.69 yuan a year, and with a 5 w LED lighting electricity is 9.25 yuan a year. Clearly, using incandescent lamp is the most economic. LED lights than your price, but cheaper electricity."He said.

　　In the customers to buy lamps and lanterns, asking leds accounted for the vast majority of customers.A customer said: "although leds is higher than price, but with long time can save a lot of electricity, by contrast or it's a good deal."

　　The deputy director of the institute of semiconductors, Chinese academy of sciences hong-da Chen said that if 50% of China's light in LED, can achieve energy saving 210 billion KWH, equivalent to 2.5 to build the three gorges project.At the same time, the LED in such aspects as life, application flexibility also has incomparable advantages.

　　Leds lack of national standard market be regulated

　　Building materials market in the middle of zhejiang, the citizens to buy lamps and lanterns liu said: "the home has been used energy-saving lamps, but short life feeling energy-saving lamps, it broke in less than two years, so I would like to change the LED lamp. But after the inquiry found that prices vary considerably, oneself also don't know what good buy."Now in the market of LED lights prices vary considerably, such as philips, panasonic and other well-known brands of LED lamp price between 80 yuan to 150 yuan, but some of the unknown LED lights price is less than 50 yuan.

　　"Why the LED lamp price differ so big?""We have the lamps and lanterns of imported and domestic, import price expensive, domestic is relatively cheap."When reporter questioned price of LED lights, one of the lamps and lanterns store salesperson replied.

　　Whether the LED lights on the market as the salesman said "you get what you pay for"?Reporter learned from relevant departments, at present our country has not issued national standard about LED lights, LED lights on the market are mostly in accordance with the enterprise since the standard production, quality is good and bad are intermingled, consumers generally difficult to understand the "doorway".

　　Is also a LED lamp, what factors affect the price?To this, explanation of one industry source, the factors influencing price of LED lights including chip, encapsulation, thermal radiation, heat dissipation material, process, etc., appearance points several level chip alone.

　　The people in the industry to further explain, a LED lights usually includes light beads, shell, drive three parts.With a rated power of 3 w LED to shoot the light, for example, the three lamp bead, a shell, a drive, with intermediate products production cost calculation, the cost of the lamp bead is 2 yuan, shell is 3 yuan, driving is 2.8 yuan, artificial cost is 0.5 yuan to 1 yuan, packaging cost, other cost for 1 yuan.So, the only light of the total cost is 10.3 yuan.Coupled with the businesses to earn profits, warehouse rental cost, transportation cost and so on, the only light at least also want to in more than 20 yuan.So the price only 10 yuan or lower the quality of the LED lights all too clear.

　　In addition, partial businessman dare to sell very cheap LED lights, because the use of inferior materials, lights, for example, an inferior 1 w domestic lamp bead in the market the lowest price is 0.2 yuan, only this kind of lamp beads in gold thread is replaced with copper wire and other materials with too much is bad products.For these, the consumer only from the appearance of the lamp is difficult to identify.As a result, he warns customer, do not buy low price of LED lights, so as to avoid problems when use, cause harm to themselves and their families.

　　"Store some LED lights look brighter, and some are dark, what reason be? There are all sorts of color LED lights at the same time, exactly what color of light won't damage eyesight?"Customer ms yu to salesman to ask these questions, the lamps and lanterns shop salesman but not answer.

　　Experts advise students to use the LED lamp

　　Experts said that although overall ratio of almost all kinds of table lamp, but more advises students use the LED lighting lamps.Experts explain, incandescent lamp is through the heating effect of the tungsten filament, the working principle of the working principle of energy-saving lamps and fluorescent lamps, the transmission electron impact by heating filament argon atoms and mercury atoms emit ultraviolet light, and ultraviolet stimulate phosphor luminescence.Therefore, energy-saving lamps produce stroboscopic light, high frequency energy-saving lamps will produce electromagnetic radiation, used for a long time for the child's eyes is easy to damage.

　　And LED lamp is to use light-emitting semiconductor electronic effect, is a low voltage dc constant current source of light-emitting devices.So there is no stroboscopic of energy-saving lamps, electromagnetic radiation and other issues, it is recommended that students lamps using LED lamp lighting.

　　Leds generally divided into white light and yellow light, consumers can choose according to need.Leds are different degree of light and bright, light color is different, this is due to the light source of light and color temperature is different.A few small factory to make the lamp looks more bright, the color temperature as high, but in this environment for a long time easy to damage the eyesight.When buy, consumer can be hand stretch to light, the color of the hand, show color temperature just right, or color.If palm blue or purple, color temperature is too high, unfavorable buy.
