Requirements to meet the increasingly demanding products of home LED lighting applications market, a new generation of offline LED driver with electrical isolation, high efficiency, power factor correction and Triac dimming and other functions, and provide a good adjustment of the current in order to maintain consistent brightness, various protection functions, and improve system reliability.
In the past few years, the display backlight applications has been the main factor of the drive light-emitting diode (LED) market is growing. However, today's LED general lighting in commercial and residential market is becoming more attractive, to further accelerate the growth of led power 10w market. According to market research firm LEDinside research report, the rapid growth in commercial high lumen LED lighting system in 2010. This is because most consumers, the domestic LED lighting is still too expensive. In contrast, car parks, offices, factories, warehouses and other commercial areas, the LED lighting can bring long-term benefits of energy saving and environmental protection, and related tax policy, these applications of LED lighting usage will grow significantly.
Home LED lighting market growth to accelerate
led 1w lights can not only replace high pressure sodium, halogen and incandescent lamps, can replace the energy-saving fluorescent lamps (CFL) and fluorescent in some areas. LED commercial lighting will grow rapidly and widely adopted in 2012, is home LED lighting key.
In commercial buildings, 25 to 40 percent of the general lighting of the total energy usage, so the business applications to switch to LED lighting, in fact, not surprising. Such applications require high-intensity lighting a long time, so save electricity caused by the economic return would be relatively short-term. In addition, the led power 50w attachment for a long life, and therefore significantly reduce the replacement cost of the LED lights. Replacement costs not only include the cost of lighting, including hands-on replacement labor costs, usually in some applications, such as the dismantling of the high-end lighting applications, and those in need of professional-grade labor costs are very high.
Overall, the focus from the perspective of most consumers, and common household LED lighting is still too expensive, however, with the LED attachment prices fell and the LED is more widely available in the future, the lighting market in the residential sector will also be a substantial growth. Most analysts expect the residential market growth to accelerate after 2012.
led 10w IC designed to consider the multi-multi-faceted
As previously mentioned, the main driving factors behind the high growth rate of the LED lighting market is reducing power consumption. Compared with incandescent lighting to provide the same light output (in lumens), 20% of the electric power LEDs require less than incandescent. As shown in Table 1, LED lighting, there are more advantages, but there are more challenges. The advantages of LED life expectancy is longer than incandescent bulbs, which greatly reduces the cost of replacement; in particular, is able to use the previously installed two-way silicon controlled rectifier (the triac is) Dimmer for LED dimming is also a major advantage in the residential lighting market. High Power LED 50W lights can be switched in real time, no need to warm-up time as CFL and LED lights on the power cycle is not sensitive to this point with CFL lamps. In addition, a subsidiary of LED lighting devices without any need to control or handling toxic materials, while the CFL toxic mercury vapor. Finally, the LED can achieve a new and very flat form factor, while others can not do.
