Lumen may measure the next generation of light bulb standards

For more than a century, buy a light bulb is a fairly straightforward and clear transactions -- people from the packaging marked tile to determine to buy what kind of bulb. But a new policy that the United States has been implementing since the beginning of this year - a measure of brightness as a measure of the next generation of light bulbs, may change the light of consumers' minds in the long - term purchase of light bulbs. It is reported that the U.S. Federal Trade Commission proposed that all bulbs should be reflected in the brightness of the lumen (luminous flux).

"Experts Chinese Metrology Institute Li Zaiqing told reporters that this approach to help people choose the appropriate lighting brightness, so that people don't think about is how many watts bulb, low wattage bulbs for manufacturers to produce more and more such as.

For more than a century, buy a light bulb is a fairly straightforward and clear transactions -- people from the packaging marked tile to determine to buy what kind of bulb.

But a new policy that the United States has been implementing since the beginning of this year - a measure of brightness as a measure of the next generation of light bulbs, may change the light of consumers' minds in the long - term purchase of light bulbs.

It is reported that the U.S. Federal Trade Commission proposed that all the bulbs should be reflected in the brightness of the lumen (luminous flux unit) on the front, the number of tiles marked in the energy below.

Also, it is necessary to indicate how much of the energy consumed by the bulb is about the energy consumption per year, the life of the lamp bulb and the intensity of the cold light or the warm light.

"This means that the number of tiles in the future will no longer be a measure of the bulb's brightness. "Experts Chinese Metrology Institute Li Zaiqing told reporters that this approach to help people choose the appropriate lighting brightness, so that people don't think about is how many watts bulb, low wattage bulbs for manufacturers to produce more and more such as. At the same time, from the perspective of the quality of light bulbs, but also a more objective measure.

A new measurement way also reflects the vice chairman of the association of lighting energy-saving lamp China and Secretary General Chen Yansheng told reporters that China's lighting and other lighting products, has been number of watts and mark lamp lumens, is different, the wattage marked in a conspicuous location, larger fonts, new policy of the United States and North American countries. This is the mark, lumen units referred to a more important position, the lighting product label and logo impact.

Li Zaiqing believes that the photometric measurement from the background to move to the front desk, this seemingly insignificant changes, but for energy-saving lamps to replace incandescent lamps to create the conditions, but also for countries to promote energy-saving emission reduction played a role model.

It is understood that people often talk about the daily life of the bulb "bright" or "not bright" concept, in fact, refers to the light emitted by the bulb to the object, the object reflected into the human eye and the "bright" feeling. This "bright" feeling in the photometry is called luminous flux, luminous flux is "bright", "dark" luminous flux, luminous flux measurement unit is called lumen. That is to say, the number of bright lumens is large, and the number of dark lumens is small. "The number of bulbs of the same wattage may vary. In general, the higher the number of lumens bulbs, energy-saving effect is better.

Chen Yansheng explained, referring to the number of light bulbs to buy, consumers can more clearly understand the energy efficiency of the bulb. With halogen tungsten lamp, three color fluorescent lamp, compact fluorescent lamp (commonly known as energy-saving lamps), metal halide lamps, to meet the needs of a variety of lighting environment. "They are characterized by high luminous efficiency, long life and good color. In particular, energy-saving lamps, the light effect is about 3.5 times the incandescent lamp, that is to say, a 15W energy-saving lamps and 60W lights as bright, and life expectancy of 10 times. Li Zaiqing said that although the one-time investment in energy-saving lamps is greater than the light, but the overall price and the lamp is comparable, but also to further reduce.

The industry generally believes that the ultimate form of light bulbs are light-emitting diodes, that is often said that the LED lamp, is in the commercialization of R & D stage. It is characterized by both to overcome the mercury pollution of energy-saving lamps, life and light efficiency is higher than the energy-saving lamps. Energy saving lamps have been commercialized, is gradually replacing incandescent. The emergence of these two lamps, in order to replace the lamp to lay the material foundation, but also for the lighting project to create new opportunities for energy saving and emission reduction.
