What‘s the analysis of the lighting application of the Low power LED general lighting

In recent years, lighting has become an important area the world are aimed at to promote energy saving. According to statistics, about 20% of the electricity is used for lighting every year, of which about 40% is used for inefficient incandescent lighting. And with continuous improvement of the output performance, cost, and almost all aspects of the LED light, LED general lighting has become an extremely compelling alternative to incandescent and other traditional lighting.

A typical applications of the LED general lighting, including replacement bulbs and fluorescent tubes, Downlights, street lights and parking lights, working lights, landscape lighting, billboards text circuit, building lighting. The high power LED street light and LED tunnel light is generally between 50W to 300W; the applications power of the LED light used for lighting buildings and general area is between 40W and 125W , which belongs to the medium power range; 30W or less may be referred to the low-power LED lighting applications, including specific point lighting, interior lighting such as cabinets, recessed lights, spotlights PAR20/30/38 alternative lighting, tabe lamps, etc., as well as omni-directional lighting, such as accent lighting, household appliances, general lighting A-type lamp replacement, decorative lamps and ceiling fan lights . This article will focus on the applications of the low-power general lighting that is below 30W LED, as well as the corresponding Semiconductor energy-efficient solutions.

The factors that the applications of the Low-power LED lighting select the drive need to be considered The main function of the LED driver is to limit the current range under the operating conditions, regardless of how changes in the input and output conditions. Its application design faces a variety of Limited conditions, such as the high efficiency, high cost, wide environmental conditions, high reliability, flexibility, other aspects of the standard that is compliance with the electromagnetic interference and harmonic content, and those that can be modified for existing applications or the traditional control methods work that can be used. It is not easy to select the appropriate application for the low power LED driver, different factors need to be taken into account. For example, the operating temperature, duration of use, performance, and "Energy Star" and other industry standard requirements of the LED lamps are not the same on the commercial and residential market. In addition, there are also unique challenges on the replacement applications of the lamp, such as the heat restrictions of the LED drive and power supply, the size is limited and compatible dimming technology.

As far as the applicable standard of the LED general lighting is concerned, which is mainly power factor correction standards of the United States, "Energy Star" and the total harmonic distortion limits of the International Electrotechnical Commission and the European Union. Among them, the standard of the "Energy Star" V1 version requires LED lighting fixtures with PFC, suitable for embedded lights, cabinet lights and lamps and other specific products, but has nothing to do with the power level. This standard requires that the power factor (PF)of the residential applications is greater than 0.7 and the commercial applications is greater than 0.9. This standard is a voluntary standard that had be implemented in September 2011.The standard of the "Energy Star" Version 1.1 of the integral LED bulbs was put into force in August 2010, requiring the power factor of the lamp whose input power is higher than 5W is greater than 0.7. As mentioned earlier, many factors must be considered to select the appropriate drive for the low power LED lighting applications, of which, such as the industry standard for the power factor is particularly important.

The Lead lighting is confronted with the new standard the "Energy Star" issued, continuing to strengthen the use of certified raw materials such as LED chips, LED drivers, heat sinks, shell, etc., and improve R & D and production team, striving to adopt the best materials and technology to produce best quality LED flood light, LED tunnel light, LED tube light and other indoor and outdoor lighting, using highly integrated high-brightness COB as the light source of the LED Flood light and LED tunnel light and other outdoor lighting,adopting high brightness SMD LED as the light source of the LED tube light, the low-voltage constant current driver ensure the alternating current can be convert into direct current so that improve the energy use and reduces the stroboscopic effect stimulating the human eye, fully guarantee octahedron illuminated area of LED flood lights and bright light to adapt to outdoor open environment ,the soft and bright light of the LED tunnel light and LED tube light makes us safe driving in tunnels and enjoy work and study.As an ISO 9001:2000-certified factory,the lead lighting can meet the strict standards of CE, RoHS, FCC certificate, these strict producing standards guarantee our products distribute smoothly both in domestic and international markets. visit to Learn more vivid and specific characteristics of the LED tube light or click for more detailed and professional LED tunnel lights or return homepage for other LED lighting.
