LED in the use of home lighting is still in the auxiliary light stage

In 2009, the global leader in lighting -- PHILPS, LED Home Furnishing high-profile lighting in the main direction, at the same time Home Furnishing lighting giant OPPLE also officially launched Meizu dimming remote LED ceiling lamps, so that we can not help but see the white LED lighting Home Furnishing potential and hope.

However, Chen Dahua, a professor with Fudan University's Institute of electric light source but calmly pointed out: "the development potential of the LED in the field of lighting is very big, but it is the main research difficult lighting and product quality is far from mature is an indisputable fact. "In the field of LED lamp do" fast "Liquan lamps general manager Tan Haoyuan also use of LED in Home Furnishing in lighting is not optimistic, he said:" LED can assist in the starting point up, Home Furnishing lighting, if it is used as the main lighting, it is more difficult to. This also means that LED as the main light source into the homes of ordinary people, but also need more time.

Highlight the advantages of LED lighting

For consumers, in order to create a warm home atmosphere, lighting is essential, light projection on the ground, walls, furniture, brought about by the magic effect is difficult to describe the language. Therefore, in the choice of home lighting, consumers in addition to the value of the style, but also pay more attention to the product performance of the lighting effect, and the effect of lighting is the lighting source. Therefore, home lighting on the light source put forward certain requirements.

LED is a solid state semiconductor device that can directly convert electricity into light. The utility model has the advantages of the traditional light source, and can be applied to the requirements of the light source in the household lighting. The specific performance is as follows: 1. LED use low voltage power supply, is a kind of power supply than the high-voltage power supply security, which is safe for the supremacy of the household consumer groups, very suitable; 2, energy saving. The energy consumption of incandescent lamp is light efficiency by 80%, consumers can not only save energy but also can save money, is about 3, shoot two hawks with one arrow; environmental protection. LED is made of non-toxic material, will not pollute the environment, can be recycled, it is suitable for families; 4, long life. The theory on the life span of 100 thousand hours, 50% for the initial decay; 5, durable. LED is basically a very small chip encapsulated in epoxy resin, stronger than a light bulb and fluorescent tube; 6, compact. It can be fabricated into various shapes, and is suitable for the changing environment, but also through the lamp design and Home Furnishing environment of organic integration, to see the light but not light effect; 7, adjustable brightness and color, can meet the requirements of the Home Furnishing lighting color atmosphere.

More importantly, due to the controllability of LED light source, can bring home lighting into the era of intelligence. LED can be combined with the computer, make full use of the characteristics of its dimming, full color temperature adjustment, the construction of intelligent lighting system, at a specific time to provide consumers with the most comfortable and efficient lighting. For example, OPPLE has launched a "Meizu" dimming control LED ceiling lamps, can adjust the brightness according to different scenes of life, but also equipped with a remote control switch, can be realized through remote control delay off 30 seconds or 30 minutes later, provides convenience for people's life.

Technology and supporting design needs to be improved

As the general manager of TNV Telek Shi lighting division Liu Yun said, at present, LED is still in the early stages of growth in Home Furnishing lamps. Despite the advantages of LED into a lot of home lighting, but LED lighting is not perfect, the technology also needs further development. For example, the output power and luminous flux of LED lighting products, two optical design, thermal design and other issues need to gradually improve.

In this series of problems, Liu pointed out that LED used in home lighting, the biggest problem is the heat problem. Because of the limitations of LED light-emitting principle, the need for its structural parts in the premise of ensuring safety can also have a cooling function. If the use of ordinary plastic materials, LED lights will soften a few hours. Therefore, in order to guarantee the life and safety of the lamp, LED light source of the structure of the design and material put forward higher requirements.

At present, the market is generally used in the heat dissipation material is aluminum, but aluminum is relatively expensive metal, make kitchen lamp price is too high, the market is difficult to accept. "Usually do products, choice of materials Nairewen to reach 120 degrees. When we carry out the research and development of the LED kitchen lamp, we use the PC raw material of Bayer in Germany to do the experiment, it can be flame retardant, weather resistance, temperature resistance can meet the requirements. And as the main source of home lighting, LED lights in the light effect, color rendering, color temperature, power and other issues also need to be resolved.

"In the production process, compared with the traditional Home Furnishing lighting, LED lighting Home Furnishing different points are: 1, high temperature, high pressure and low pressure lamp aging procedure is different; 2, electrical control, alternating current control changes, because the LED is to direct current; 3, collocation design material shape, internal structure to have the corresponding change, with particular attention to the breaking device, such as lighting and LED light source can be relatively independent operation without mutual influence. "When it comes to the production process of LED Home Furnishing lighting and lighting at the chairman Li Junjie road. Due to the different production processes, and consumer choice "of Home Furnishing lighting style first" mentality, the application of LED in Home Furnishing lighting requirements, products quality, style design, materials and other aspects of the extension will be higher.

Cost is the biggest bottleneck

Insiders said: at present, the reason for the delay LED
