Currently, the global lighting market changes rapidly. Is well known that incandescent era is over. Incandescent lamps from the historical stage may lead to a flurry, but it can save money, protect the environment.
Today, various types of lighting products, including incandescent, halogen lamps, compact fluorescent lamps (CFL lamps), light-emitting diode (led lights), and its size, shape, color variety.
National non-profit energy-efficient lighting experts BrianFortenbery Electric Power Research Institute, said: "Lighting has a very broad market space for development, but by no means a technical game. "
Driven by changes in lighting products in 2007, Congress enacted an Energy Independence and Security Act, the bill establishes energy efficiency standards for lighting equipment, and to determine the January 1, 2012 began a phased implementation. The bill requires the energy consumption of new light by at least 30% less than the standard incandescent light up, so can not use incandescent lamps.
According to statistics, home lighting energy consumption of household energy consumption in the United States accounts for about 15%. According to energy efficiency advocates say, according to the family unit of electricity $ 143 a year basis, the new Act will set standards for U. S. consumers to save each year over 10 billion U. S. dollars, the number of new power plants will be reduced by 30. In view of this, out of incandescent lamps, switch to new energy-saving lamps is imperative. The following are the advantages and disadvantages of several alternatives to compare incandescent description:
Halogen
People are accustomed to using incandescent, halogen and incandescent lamps as the most similar to incandescent lamps may be used as the preferred alternative. Halogen bulb is the halogen gas injection, at a high temperature, evaporation will be re-solidification of tungsten in the tungsten, the formation of equilibrium cycle, to avoid premature rupture tungsten, therefore, compared with incandescent lamps, halogen lamps last longer, energy consumption is also reduced by 25%. In addition, although the appearance and performance halogen and incandescent lamps are similar, but life is two to three times that of incandescent lamps; and CFL lamps compared to the price low, the light is adjustable.
CFL lamps
In addition to halogen lamps, the energy-saving compact fluorescent lamps can also choose the CFL lights, Although this type of lighting available for decades, but because of its bulky and heavy, start time is long, and expensive, so the slow pace of development. However, the development so far, CFL lighting has evolved into a cheaper, brighter light, lighting, and the latest upgrade of the CFL lamp can also be dimming. Compared with incandescent lamps, CFL lamps reduce energy consumption by 75%, the service life is 10 times higher than incandescent lamps. CFL lamps and other fluorescent lamps contain a small amount of mercury as a result, many large home stores offer mercury recycling services.
Most of the CFL lamp start-up time is longer, take a few minutes to reach full brightness level. United States, GE has just announced a mixed halogen-CFL lamps, the lamp to reach full brightness immediately, is expected to be available this spring.
LED lights
Currently, LED lighting technology is at an early stage of development. LED light heavy, light dim. Compared with incandescent lamps, LED lamps reduce energy consumption by 80%, 15 times the service life of incandescent. In recent months, the bulb giant Philips Lighting Company and the United States OsramSylvania jointly released a warm, shape similar to traditional incandescent 60-watt LED lights. Up to now, the new LED lights costs about $ 40 / only. According to director of marketing for Philips Lighting introduced, each LED lights in its useful life on average save consumers $ 142
ESL lights
Including new lighting invented by New York's ESL Vu1 lights, but is currently limited to online sales. ESL lamp instant start, adjustable lighting, do not contain mercury. ESL 19.5 watts equivalent to 65 watt incandescent lamp, the price of each lamp ESL less than 20 dollars, energy efficiency and price range of CFL lamps and LED lights between.
With the increase in light type, the unit "Watt" will gradually become the past, but had kind of lighting will use the "lumens" as its units. "Lumen" is used to describe the brightness of lights, "Watt" is used to describe the lighting of the electric power. Watts for a single type of lighting times, but now various types of lighting, for example, a 60-watt LED light consumes only 12 watts, w can not be completely clear in this description of many types of light generation efficiency.
According to another report, this summer, the U. S. Federal Trade Commission will launch a new label the latest lighting rules, including brightness, life expectancy, appearance, power consumption and annual energy costs.
