Cost is the barriers of LED into the home market

High efficiency, energy saving, environmental protection, high life and other features make the LED to become one of the most promising applications in recent years. LED commercial lighting applications has been widely recognized and accepted, and began to penetrate into the home lighting. However, high prices and device reliability, efficiency, thermal design constraints and other technical challenges popular led street light with solar panel in the home, and therefore, how to break the price barrier and solve technical problems become an issue over the first semiconductor manufacturers must face.

Compared with commercial lighting applications, a huge consumer base makes the LED home lighting market of great concern, but the market is extremely sensitive to the cost of the home, which led to the slow pace of its development. Maxim's HBLED Product Line Business Manager PieroBianco pointed out that "the key factor restricting the application of LED lighting into the home is the cost. For other technologies (fluorescent is its main competitor) compete for market share, LED lighting prices must be controlled within 10 to below $ 15. "Texas Instruments (TI) senior technical marketing engineer Liu Chao also has agreed to this," Although the cost of LED is gradually reduced, but compared with traditional CFL energy-saving lamps, there is a price difference. "

LED bulbs cost mainly from three aspects, including high-power LED light source, LED control chip and lamp shell material is used to achieve good heat dissipation. By reducing the cost of the drive is one of the entire effective method to reduce the cost of the LED system. Using a single-stage transformation drive, direct AC power supply, which can effectively reduce costs. Another approach is to avoid using electrolytic capacitor in the drive, since higher operating temperature of the LED lamp, advanced electrolytic capacitor must be selected to maintain a sufficient driving circuit life. Therefore, if the drive does not require the use of electrolytic capacitors, will save the corresponding costs. The company has introduced a single-stage transformation, no electrolytic capacitors led street lighting Manufacturer driver program.

No doubt, improve the technical level will help drive the successful application of LED lighting in the home. High brightness LED luminous efficiency in the past few years has been a huge boost, with luminous efficiency, service life and reliability of continuous improvement, market attractiveness and value of LED lighting will continue to increase, the use of in the family rate will thus gradually increase. In addition to price, to product truly competitive in the domestic market, high brightness LED lighting solutions must also provide dimmable options. By increasing the dimming function, so users need to adjust according to the actual brightness of the lamp, but also help reduce power consumption.
