LED lamp price is no longer superior or future lighting lamps and candles of a myriad families

Home LED lamp prices no longer high

From October 1st this year, China will ban the import and sale of more than 100 watts of general lighting incandescent lamp, which is undoubtedly a good news for the LED to enter the civilian market. At last week's Guangzhou lighting show, the pace of development of civil products LED suddenly accelerated, the formation of a more abundant product applications. Although most of the site is still mainly commercial lighting display, but many companies have also launched a series of home LED products.

Each of these new features in the focus, cold light, warm light, and some can even adjust the color of the light. Compared with the past to create a relatively high-end products, manufacturers are beginning to realize this year to close the life of the product can be widely used. For example, can control the illumination range of LED bulb, the bulb can according to their own needs to adjust the illumination range and angle; also can control the temperature of the LED panel lights, to meet the different needs of scene space; 64 pixel full-color mirror lights and very colorful decorative effect.

LED lighting into the civilian market is the trend of the international lighting giants are optimistic about the future market. In this exhibition, the world's second largest manufacturer of optoelectronic semiconductors OSRAM LED products to display high quality, flexibility, easy installation features. One of the newly launched PrevaLED light engine, color rendering index as high as 90, through the active color temperature control technology to maintain a high degree of consistency between the light color of the module to solve the phenomenon of partial color LED lighting. Booth design PHILPS as a "light Theatre", the Pyramid project site transparent waistline and 3D image, the most concern is it suitable for mass consumption in this year launched two LED bulbs: Xpress series candle lamp bulb and lamp shape, unique design, bright brilliance. Decorated for elegant and warm family atmosphere; the series is 6W and 9W two specifications of the bulb, the light bright and soft, especially suitable for the replacement of incandescent lamp and energy-saving lamp. The GE this year launched the GEInfusionLED module, with the smallest screw in design, without replacing the entire lamp can replace the light source, the operation is very convenient.

At present, China's lighting industry is in a revolutionary change period, the incandescent lamp will be eliminated, energy-saving lamp very influential, LED just unfolding. LED light is a technological revolution in the lighting industry, a typical LED lamp than saving 70%~80% energy saving lamp, energy-saving lamp life is 4 times, but the price is 3~4 times of the energy-saving lamps, high price has become an obstacle to the popularity of home LED. In this exhibition, on the side of the lighting in the LED lighting has a new breakthrough in the, a 7W bubble ball only 100 yuan special offer. Equivalent to the price of 33 yuan per bubble, compared with the traditional incandescent lamp is not cheap, but the mainstream brand of energy-saving lamps, the price gap has been a substantial reduction.

Key technology bottlenecks have a new breakthrough

Over the past few years, although the prospects for the development of LED is very rapid, but the process of household popularity is very slow. This is not just 'price', 'mass production' and other issues, in addition to consumer acceptance issues, there are some technical bottlenecks did not break. According to the "China lighting association director Wang Jinsui introduction, this led to the LED bean lamp on the market, LED lamp, LED fluorescent lamp compared with the traditional lighting is still a big gap, far better than that so well.

At present, the domestic market in the form of the trinity of LED products, including three key elements: light source, power supply, heat dissipation. Light source is the core of the whole product, chip technology for Europe and the United States and Japan, most of the domestic enterprises to use the purchase of assembly. Therefore, although the LED threshold is not high but want to do a good job, we must solve two key issues - heat, power supply. In contrast, the challenges of driving power supply is mainly concentrated in the outdoor lighting climate environment, heat dissipation is a major obstacle to the home LED high power lighting. According to industry sources, in Zhongshan Ancient Town and other places have a lot of LED assemblers, simply assembled into the traditional LED light source lamp, heat, light, two optical design is not satisfactory, life can not reach the ideal value.

LED cooling is not good, will cause the decay of life will be greatly reduced. In this exhibition, the reporter found that this technical problem has a new breakthrough. From Shenzhen friends billion into completely subvert the cooling way of ordinary LED, first introduced the new fin type LED indoor lighting series, ceiling lamp, downlight, including other light etc.. According to its general manager Shiyan introduced, it can save more than 4 of aluminum, the weight is only the traditional lamp 1/3, through more efficient heat conduction heat dissipation, to meet the reliability and life requirements of domestic LED. Aiming at the problem of high power LED radiating hundreds of watts, from China Academy of Sciences Institute of Engineering Thermophysics of display of the "National 863 Plan" one of the latest research results of micro grooves phase change composite cooling technology, become a highlight of this year's show. At the scene, the reporter saw this light weight, small size, low cost and efficient radiator, the maximum power dissipation can be as high as 1KW. The development of the technology, the National Natural Science Foundation expert Hu Xuegong told reporters, don't look at it is simple and compact, but the cooling ability, heat flux density up to 400W/c square meters, 1000 times higher than the water cooling, heat pipe is about 100 times higher. "It fundamentally solves the technical bottleneck problem of the existing LED heat sink capacity and total heat dissipation. "

However, LED can enter the household, the key depends on whether the price down? At present, the production of LED chips accounted for 60% of the total price, with the light
