Application of LED in lighting engineering

Is projected to a region of the building, is nothing more than a light use round shape control and direction of the beam, which is consistent with the traditional concept of light. However, due to the LED light source is small and thin, the development of linear projection lamp will undoubtedly become a major highlight of the LED projection lamp, because the light of many buildings no special place of traditional. The installation of the utility model is convenient and can be installed vertically or horizontally, and the utility model can be combined with the surface of the building, and the utility model brings new lighting words for the lighting designer, and the creation space is expanded. And will have the influence to the modern architecture and the historical building illumination method, as shown in Figure 12, figure 13. Landscape lighting because unlike traditional LED lamp light source is glass bulb, it can be combined with city street furniture good. Can be in the city's leisure space such as roads, staircases, decks, waterfront areas, horticulture lighting. For flowers or low shrubs, LED can be used as a light source for lighting. LED hidden light emitting lamps will be particularly favored. The fixed end can be designed as a plug-in type, which is adjusted according to the height of the plant. Logo and indicative lighting need space limited places and guide, such as road pavement, stair treads separate display local lighting, emergency exit indicator lighting, can use the surface brightness of appropriate self luminous LED underground lamp or block in the vertical wall lamps, lights like theater audience hall ground guide lamp or the side of the seat, and the shopping center floor guide lamp. In addition, LED compared with neon, because it is low pressure, no fragile glass, not because of the increase in the cost of bending, it is worth promoting the use of logo design. Indoor space display lighting on lighting quality, because there is no heat, LED light source of ultraviolet and infrared radiation, cause damage to the exhibits or goods are not, compared with the traditional light source, the lamp does not need additional filtering device, simple lighting system low cost, easy to install. The precise lighting, can be used as a substitute for Museum lighting. Commercial lighting will use the color of the LED, indoor and outdoor decorative white LED combined with interior decoration to provide indoor lighting, hidden band can use LED, especially for low space. Entertainment and stage lighting LED due to the dynamic and digital control of color, brightness and color saturation lighting dimming, lively can create static and dynamic. From the white to the full spectrum of any color, the use of LED in this kind of space lighting opened a new way of thinking. Long life, high lumen maintenance value is still 10 thousand hours after the maintenance of the luminous flux of 90%, compared with the PAR lamp and metal halide lamp 50~250 hours of life, reduce maintenance costs and the frequency of replacement of light source. In addition, LED overcomes the phenomenon that the color of the metal halide lamp is used for some time. Compared with PAR lights, no heat radiation can make the space more comfortable. The application of LED color decorative wall in the restaurant in the building has become a common practice. The video screen full color LED display is one of the world's most eye-catching large outdoor display device, using advanced digital video processing technology, a large area can be compared with high brightness. According to the different indoor and outdoor environment, the use of a variety of luminous pixels, to achieve different brightness, color, resolution, to meet a variety of uses. It can dynamically display graphic animation information, the use of multimedia technology, can play all kinds of multimedia files. The world's most influential LED display, the United States, Manhattan Times Square, the New York stock exchange, a total of 18677760 LED, with an area of 10736 square feet. The screen can be divided into a number of pictures, while at the same time, the Wall Street stock market will be presented in front of the public. In addition to the rise in Shanghai Pudong Lu Jia mouth financial center Aurora international headquarters, the entire building toward the Xiangshang Puxi screen super LED long 100m, a total area of 3600 square meters. World first. And industrial design combined LED is the darling of European product designers in recent years, they will be LED as part of the product design elements, gallop in the imagination of space, light, glass or other materials together, become the magnificent art.
