With the gradual improvement of the luminous efficiency of LEDs, LEDs have the potential for lighting, plus LEDs have long life, environmental protection, energy saving, good color rendering, short response time, vibration resistance, etc. Semiconductor lighting has become the goal of people fighting for it. The use of LED lighting can create a variety of very beautiful appearance and lighting, and its potential market is very large. The illuminator not only has its own appearance, but also can create a variety of lighting effects, showing people a variety of beautiful lighting patterns, which can not be achieved by traditional lighting and ordinary LED lamps. LED lighting has developed rapidly, such as the “Fantasy Little Three Gorges†in Wushan, Chongqing. The opening ceremony of the Shanghai World Expo will illuminate the banks of the Huangpu River. Foshan wants to build the LED lighting capital... 1. Definition of LED lighting LED lighting is a brand new lighting product, it is a large category of lighting, LED (light-emitting diode) as the light source of the lighting products. Lighting is the eyes of the home. If there are no lamps in the family, just like people have no eyes, families without eyes can only live in the dark, so the position of the lamp in the family is crucial. 2. Features of LED lighting The light-emitting components of the LED lighting are made into transparent sheets of various shapes, and the plurality of micro LEDs are packaged inside the sheet-shaped illuminating body: for different lamps, the partial shape of each part of the transparent sheet can also be various. For example, the surface of the illuminant is treated differently: some are made of a matte surface made of a matte effect, and some are made into various shapes of ridges, grooves, pits, bags, etc., and some are also coated. Reflective film, etc. Some reflective films are also joined to a composite material at the back. The composite material consists of leads, structural members, resin or cement, gypsum, and the like. 3. The principle of LED lighting A plurality of micro LEDs inside the sheet-type illuminator radiate toward the inside of the sheet, and the light is totally transmitted, diffused, and mixed on the smooth surfaces on both sides of the illuminator. By or through the special design of the partial illuminating of the illuminator, the transmission and diffusion of light in the illuminating body of the illuminating body is destroyed, and the direction in which the light is advanced is changed, and the light can be scattered in a designed manner in the designed portion of the illuminating body. , thus forming a variety of effects. For example, through the reflective film on one side surface and the pattern recessed into the sheet on this side, most of the light emitted by the micro LED can be scattered from one side to form an effect that the internal pattern emits light to one side. The thin-film illuminator has a illuminating manner of emitting light to all sides, emitting light to one area, emitting soft diffused light, emitting bright ray, and the like, thereby forming various artistic lighting effects. 4. LED lighting has the following advantages 1. Multiple changes: LED light source can use LED to turn on and off at the moment of current without afterglow and red, green and blue. The use of LED display screen control technology to achieve multiple changes in color and pattern is a kind of control that can be controlled at will. Dynamic light source." 2. High energy saving: DC drive, ultra-low power consumption (single tube 0.03-0.06 watt), the electro-optical power is over 90%, and the same lighting effect is more than 80% energy saving than the traditional light source. 3. Long life: LED is a solid cold light source, epoxy resin package, so there is no shortcomings such as filament light, easy burning and thermal deposition. The working voltage is low, the service life can reach 50,000 to 100,000 hours, and the service life is more than 5 times longer than the traditional light source. 4. Environmental protection: cold light source, small glare, no radiation, no mercury, no harmful substances in use. 5. Novel technology: Compared with traditional light sources, LED light source combines innovative technologies such as computer, network and embedded control, and has the characteristics that the drive circuit can be programmed online, infinitely upgraded, and flexible. 5. Types of LED lighting 1. Surface-emitting LED lighting. The simplest of these types of lighting is flat and can be mounted on a ceiling, wall or floor. This kind of lighting can also be combined with a large number of small LED lighting to form a large luminous area. It can be foreseen that the mainstream LED lighting will not adopt this structure in the future. If the LED lighting is still the structure and principle of the traditional lighting, the lighting is not only low in luminous efficiency, but also the lighting method is old and single. In terms of appearance, lighting, diversity of lighting effects, and luminaire efficiency, it is far less excellent than LED lighting made of various sheet-type illuminators, so this structure is not suitable for LED lighting. 2. The lamp is no longer composed of a bulb, a lamp holder or a lampshade, but becomes a beautiful sheet. The sheet-shaped illuminator is combined with various decorative parts and structural parts to form different sizes, different styles, and many A series of lighting. Different appearances and different lighting effects and different lighting shapes can form a variety of ever-changing lamps, which can suit people's pursuit of different effects and bring more coziness and warmth to people of different hobbies. This type of LED lighting series is the most diverse and most abundant, and can replace traditional chandeliers, ceiling lamps, wall lamps and other lighting. 3. Hanging or attaching a large number of thin-shaped illuminators to the surface or frame of various styling objects, and making outdoor lightings of various shapes such as birds, flowers, animals, sculptures, landscapes, etc., for outdoor lighting, Landscaping and advertising. The illuminator not only has its own appearance and shape, but also can create a variety of lighting effects, showing people a variety of beautiful lighting patterns, which can not be achieved by traditional lighting and ordinary LED lamps. Through digitally intelligent control, these combinations can be used to roll, flicker, run and many other changes like a large group of lights. 6. Application of LED lighting The configuration of the living room lamps should be conducive to creating a stable and generous, warm and warm environment, so that guests feel at home. A single or multi-head chandelier can usually be installed in the center of the room as the main light. For example, if there are banners and calligraphy on the back wall of the sofa, two wall lamps of appropriate size can be installed on both sides of the calligraphy and painting, and a floor lamp can be placed on the side of the sofa. Such a luminaire arrangement is stable and generous, and can be selected according to different needs. The light can be placed at the beginning of the lamp, the room is full of brilliance, or the single lamp is placed alone, and the knees are old. The study is a place for family members to work and study, requiring a higher level of illumination. General work and study lighting can use local lighting fixtures, with higher power incandescent lamps as well. The main body lighting can be used with both single chandeliers and fluorescent lamps. The position is not necessarily in the center, and can be determined according to the specific conditions in the room. The shape and style of the lamps should not be too gorgeous, elegant and elegant, creating a quiet and comfortable environment for people to read. The simple bedroom is a place for people to rest and sleep. It should give people a feeling of quietness and leisure. Avoid dazzling light and dazzling lighting. A hanging main light can be installed in the appropriate position of the room, and a bedside wall lamp can be installed on the bedside. For a multi-purpose bedroom, a ceiling-type fluorescent lamp can be installed in the center of the room. Two wall lights are installed in places where the illuminance is important. These lights are controlled by switches to meet different needs. The restaurant is the place where people dine. The table requires horizontal illumination. Therefore, it is advisable to use lamps that are directly directed downwards or pull-down lamps so that they are pulled down to a height of 600-700 mm on the table. The position of the lamps is generally at the table. Just above, in order to increase appetite, incandescent lamps with a capacity of more than 60 watts are used. Sometimes the restaurant has other functions, so it needs to have multiple sockets to serve as the power source for the desk lamp and floor lamp. The kitchen is a place for cooking and washing dishes. It is generally small in size, and most of them use general lighting on the ceiling, with a capacity of 25-40 watts. The modern kitchen is equipped with a range hood above the cooktop, usually with 25-40 watts of illumination, which greatly improves the illumination above the cooktop. In the modern kitchen, there are many cabinets above the cutting and cooking hobs. Partial lighting can be installed under these cabinets to increase the illumination of the console. The bathroom should be bright and soft. The lamps should be protected from moisture and rust. The light source should be incandescent with a high color rendering index. When using the wall lamp, install the lamp on the wall perpendicular to the curtain to avoid reflecting the shadow on the window. When using the ceiling light, avoid installing it on the bathtub directly covered by steam. The power of the wall or ceiling light is preferably 40-60 watts. 7. Development bottlenecks and countermeasures of LED lighting At the same time as the popularity of LED lamps, there have been many worrying problems, mainly in the following points: 1. No industry standard: LED is a new thing. All manufacturers develop various products according to market needs. The more standardized enterprises design circuits according to the characteristics of LEDs. The quality of products is relatively stable, but many companies are eager for quick success. LED products As long as it can be lit, the LED luminaire will not reach its nominal service life. 2, no core technology: At present, most of the LED chips come from the United States and Japan, and product updates and technology upgrades are subject to people. 3. Lack of supporting components: LEDs are used in the light source of lamps, and must be driven and controlled by corresponding electronic components. However, the development of related components lags behind the development of LED lamps, so that enterprises can only adopt some unreliable solutions in product design, resulting in unstable LED lamps. 4, market malformation: LED lamps are mainly engineering lamps, due to their professionalism, it is difficult for ordinary people to distinguish their quality, and engineering companies often get the highest profit, shoddy, damaged the image of LED lamps. Responsible businesses and manufacturers should consciously maintain the healthy development of the semiconductor lighting industry. Although in the field of LED decoration, LED has the characteristics that other materials can not be replaced, has been basically recognized. However, in the field of LED general lighting, although the industry is full of expectations, the final consumer market is still dealing with an enlightenment stage, especially for ordinary consumers, if you want LED lights to enter thousands of households, you still need A longer process. The price factor will become a primary bottleneck for domestic consumption. At present, for the MR16 spotlight, the price at the current cost will be above RMB100, while the price of an ordinary MR16 halogen lamp is only RMB 8 for the RMB. about. If it can't be reduced to 2-3 times the price of traditional lighting, this replacement will be difficult to achieve. It must be said that China is still in an era of extensive economics, and the awareness of energy conservation and environmental protection is still weak. However, in order to have a substantial decline in cost, it is first required to have a major breakthrough in technology. 1) Further improve the luminous efficiency of high-power LEDs and reduce the number of light-emitting sources to reduce costs. 2) Find new ways to dissipate heat. At present, aluminum alloy heat dissipation is used, and the cost is very high. And the higher the luminous efficiency in the future, the higher the cost of the heat dissipating components will increase. 3) LED optical lens Due to the technical confidentiality of the industry, only a few manufacturers produce, so the price is also high. Therefore, the fate of LED lighting manufacturers can be said to be in the hands of its upstream material suppliers. Although some expect 2 years - 3 years - 5 years, there are opportunities. But what we need to think about is: When is the best time to enter the domestic market? How to make us stand out from the crowds of manufacturers? How to make our products differentiate to avoid simple price competition? Put our technical strength in Shape design or electronic design? How to find a cost-effective and beautiful cooling solution? Where are the other breakthrough points? 1. The refinement of lighting and the resulting trend of civilian use and its support for the development of patch components and lamp beads; 2. High-power lamps; 3. Expanded use of the industry; 4, LED lighting. This is the four directions of the future. In the process of developing in these directions, there will inevitably be perfection of brands, channels, and featured products, accompanied by formal management. The 21st century will be based on solid luminescent materials, the new century, green lighting source represented by LED. In the future, with the advancement and improvement of the production technology of LEDs, the luminous intensity and stability of LEDs will be greatly improved. It is believed that in the future of the 21st century, lighting and lighting products with LED as a light source will inevitably replace ordinary lighting sources, and become another revolution in the history of human lighting.
