1. The projection of building exterior lighting to a certain area of the building is nothing more than the use of round head and square head projection lamps to control the beam angle, which is completely consistent with the concept of traditional projection lamps. However, due to the small and thin LED light source, the research and development of linear projection lamps has undoubtedly become a highlight of LED projection lamps, because there is no place for traditional projection lamps in many buildings. It is easy to install and can be installed horizontally or vertically. It is better combined with the building surface, which brings a new lighting vocabulary to lighting designers and expands the creative space. It will also have an impact on the lighting methods of modern and historical buildings.
2. Landscape lighting LED lamp effect drawing because LED is not like traditional lamps, the light source is mostly glass bulb shell, which can be organically combined with urban street furniture. It can be illuminated in the leisure space of the city, such as path, staircase, deck, waterfront and gardening. For flowers or low shrubs, LED can be used as light source for lighting. Led hidden projection lamps will be particularly popular. The fixed end can be designed as plug-in type, which can be easily adjusted according to the height of plant growth.
3. For places where space limitation and guidance are required for identification and indicative lighting, such as separated display of road pavement, local lighting of stair steps and indication lighting of emergency exit, led self luminous buried lights with appropriate surface brightness or lamps embedded in vertical wall, such as ground guide lights in the auditorium of the theater or indicator lights on the side of seats, And the guiding lights on the floors in the shopping center. In addition, compared with neon lights, LED has low pressure, no fragile glass, and will not increase the cost due to bending in production. It is worth popularizing and using in logo design.
4. Indoor space display lighting in terms of lighting quality, because the LED light source has no heat, ultraviolet and infrared radiation, it will not damage the exhibits or commodities. Compared with the traditional light source, the lamps do not need additional filter devices, the lighting system is simple, low-cost and easy to install. Its precise light distribution can be used as a substitute for optical fiber lighting in museums. Commercial lighting mostly uses color LED. Indoor decorative white LED combined with indoor decoration provides auxiliary lighting for the interior. LED can be used in hidden light band, which is particularly beneficial to low space.
5. Because of the dynamic and digital control of color, brightness and dimming of LED, the lively saturated color can create static and dynamic lighting effects. From white light to any color in the all-optical spectrum, the use of LED opens a new idea in the lighting of this kind of space. The maintenance value of long life and high lumen (90% luminous flux is still maintained after 10000 hours) reduces the maintenance cost and the frequency of light source replacement compared with the 50 ~ 250 hour life of par lamp and metal halide lamp. In addition, led overcomes the phenomenon of color shift after metal halide lamp is used for a period of time. Compared with par lamp, there is no heat radiation, which can make the space more comfortable. At present, the application of LED color decorative wall in catering buildings has become a common practice.
6. Video screen full-color LED display is the most eye-catching outdoor large-scale display device in the world. It adopts advanced digital video processing technology and has incomparable large area and ultra-high brightness. According to different indoor and outdoor environments, various specifications of luminous pixels are adopted to achieve different brightness, color and resolution to meet various purposes. It can dynamically display graphic animation information and play all kinds of multimedia files by using multimedia technology. At present, the most influential LED display in the world is the New York Stock Exchange in Times Square in Manhattan, with a total of 18677760 LEDs and an area of 10736 square feet. The screen can be divided into multiple images and displayed at the same time, which can clearly present the market of Wall Street stock market in front of the public. In addition, the rise of Sinian international headquarters in Shanghai Pudong Lujiazui financial center, the entire building facade facing Puxi is inlaid with a 100m long super large LED screen, with a total area of 3600 square meters. It can be called the first in the world.
7. Vehicle indicator lighting is applicable to electric vehicles Lighting of motorcycle and automobile lamps.
