The U.S. Federal Trade Commission proposed that all the light bulb packaging must reflect the brightness of the lumen (luminous flux units) up front, the wattage marked on the \"energy\" following. Bulb packa ging also indicated the annual energy consumption of this light bulb is about the number of lamp life and intensity of cold or warm light, it would apply to the traditional incandescent lamp, energy saving fluorescent lamps and light emitting diode (LED) bulbs. More than a century to buy light bulbs is a fairly straightforward and clear the transaction - the wattage indicated on the package to determine what kind of bulb to buy. But the United States beginning this year implemented a new policy - the brightness as a standard to measure the next generation of light bulbs, and perhaps will change the consumer mind and long-term to buy light bulbs on the formation of wattage lighting knowledge.
Vice Director Chen Yansheng of China Association of Lighting report said that the light bulbs and other lighting products in China, have been asking marked the bulb\\ s wattage and lumen difference is that the wattage marked in a conspicuous location, larger font size, the United States such as North America\\ s new policy, lumens This unit labeling referred to a more important position would be the labeling of lighting products, and signs have an impact. \"This means that wattage will no longer be the standard measure of light bulbs.\" Expert Li of the China Institute of Metrology said that this approach to help people select the brightness of light bulbs, so that people no longer think of the light bulb is how many watts because the future manufacturers will produce more energy efficient low wattage light bulb. At the same time, from the point of view of the bulb quality, but also have a more objective measure.
In the clear view that the photometer amount moved from behind the front desk, this seemingly insignificant change, but create the conditions for energy-saving lamps to replace incandescent, but also played an exemplary role for countries to promote energy saving.
It is understood that the daily life people often talk about the light bulb \"bright\" or \"light\" concept, in fact, refers to the light bulb to the object reflected from objects into the eye of the \"bright\" feel. This \"bright\" feeling called photometric luminous flux, the \"bright\" large luminous flux, the \"dark\" and then the luminous flux is small, to measure the luminous flux size units called lumens. In other words, the bright lumen and dark lumen.
With halogen, trichromatic fluorescent lights, compact fluorescent lamps (commonly known as CFLs), the emergence of the metal halide lamp, meet the lighting needs of a variety of environments. \"They are a distinctive feature of high luminous efficiency, long life, and now the color is also good, especially energy-saving lamps, the luminous efficiency is about 3.5 times that of incandescent, that is, a 15W energy-saving lamps and 60W lamps bright, and the life expectancy of 10 times. Lee said that although one-time investment in energy-saving lamps is greater than lamp, but the composite price and the par lamps, is also expected to further reduce. The industry generally believe that the ultimate form of the bulb is a light-emitting diode, LED light that is often said, is in the commercialization of R & D stage. It is characterized by both to overcome the energy-saving lamps, mercury pollution, life and lumin ous efficiency than CFLs. Energy saving lamps have been commercialized, and is gradually replacing the incandescent lamp. Both lights to replace the lamps and laid a material foundation, but also creates new opportunities for energy saving lighting project. The same wattage bulbs, the number of lumens may be different. In general, the higher the lumen bulbs, energy saving and better. \"Explained Chen Yansheng, reference lumen buy lamps, consumers can be more intuitive clear bulb energy saving effect.
Statistics show that the United States is 4.4 billion light sockets, lampholders (300 million dollars) per capita is 14.7, the world\\ s population of nearly 70 million U.S. per capita the lampholders amount of 1/5 the globe holder to $ 20.2 billion. If you use this new unit of measurement in lumens, the saving significance of the lamp and industrial development will be very far-reaching. Beijing used to extract the 53 energy-saving lamps samples for testing, results showed that the initial light effect does not meet national standards accounted for 24.53% of the total. Initial light effect does not meet the national standard light bulb, the wattage of the standard means that they, and the lumen is not up to buy these lights wattage, the interests of consumers will suffer the contrary, if the lumen to to buy the lamps, the lumen failed product nobody cares about, or only the reduced price. This shows that the modern light bulb market is an urgent need for the concept of th e lumen buy. Lee said. Chen Yansheng expression of different points of view, he thinks, even though the United States, Canada and North America have already implemented the new lamp unit of measurement, but in Europe, Asia and other regions still using traditional wattage measurement methods, especially in Europe the impact of the global lighting industry is important, the future lumen in the end whether in the global popularity, still have to watch and wait.
Lee, SD Chen Yansheng, after the publicity of the past century, the concept of the wattage in the whole society is very deeply rooted, so the popularity of this new concept of the lumen, we must start from the publicity, this will be a rather daunting task. Start \"should be developed from standard to determine the lumen of the \\ job to\\ .\" Lee Qing recommendations, together with the State General Administration of Quality Supervision, Inspection and Quarantine was established by the Ministry of Commerce bulb labels and updating of the Joint Working Group, responsible for production, domestic sales and export all kinds of light bulbs label updating organization and coordination work. Determine the contents of the new label, the enactment of the implementation of the new label to replace incandescent lamps (40 ~ 100W) time limits. The same time, the organization prepared by experts of the wattage of the bulb with the lumen of the table and related information, consumer and lighting engineering designers in the selection of light data reference. Insiders pointed out that the implementation of the lumen measurement, on the one hand, the quality of lighting products, you can visually compare, upgrading product quality and consumer environment purification; the other hand, forcing companies to pay more attention to the energy performance of lighting products and quality, industrial upgrading.
