Since the first commercial LED was introduced in the 1960s, LED has been used in the lighting industry for more than 40 years. The upper, middle and lower reaches of the industry have formed a relatively complete industrial chain. LEDs are being used in the industry. In more industries, this article will elaborate on the advantages of LED lighting sources compared to other light sources, the significance of indoor applications, the scope of application of LED light sources in indoor lighting , and the development and promotion of LED indoor lighting products. The direction. Â Â Â Â Â iVision's Lumos Drive 36 provides 2.5-4.0 kHz LED pulses instead of 50-60 Hz, which produces flashing TV images, making studio changes practical. Color-changing downlights, bird -shaped decorations, and color-changing bands create unique colors and logos for different segments. Fluorescent accessories provide conventional and backlight support for LED mounting. This system is expected to receive an equivalent return within 39 weeks . Oil-immersed Distribution Transformer, its HV level is 15kV, LV is 400V, its capacity is 2500kVA and below. Generally installed on the pole or in the distribution room, for lighting or power supply, three-phase power supply, fully sealed tank structure, to ensure the transformer safe and reliable operation.

     In the field of indoor lighting, the traditional light sources for main applications generally include incandescent lamps, tungsten halogen lamps, fluorescent lamps, PAR lamps, metal halide lamps, and the like. This type of light source consumes a large amount of power, has a single color and control, and is light.
     Speaking of LED applications, I can't help but talk about some of the advantages of LEDs over traditional light sources. These advantages are the flat point at which LEDs may be used in large areas of indoor commercial atmosphere lighting.
     LED is known as the green lighting product of the 21st century, and now almost all the world's eyes are focused on this new type of light source, compared with the traditional light source, has an unparalleled advantage:
     1, high purity, bright and rich colors. At present, LED products cover almost the entire visible spectrum and have high color purity. The traditional way to get colored light is incandescent lamps plus filters, which greatly reduces
     2, long life. The actual life of LEDs exceeds 50,000 hours, which is several times or even several times that of general light sources;
     3. There is no mercury in the light source, and the light beam does not contain ultraviolet light. LED is a solid light source, green and environmentally friendly, especially suitable for professional places such as perfume shops, jewelry stores, museums, art galleries, etc.
     4, solid light, good seismic performance, firm and reliable;
     5, energy saving, economic, maintenance-free;
     6, dynamic color control, adjustable light and dark, LED combination of three primary colors can use PWM to achieve color change
     7. LED has strong directionality of light, high utilization rate of light flux, small volume, easy to control the design of LED lamps and control of light intensity distribution;
     8, LED can be powered by DC low voltage, safe and reliable;
     9, LED is not limited by the starting temperature, can be started instantaneously, usually several ms, and can instantly reach the full luminous flux output.
     Next, talk about the application of LED in indoor lighting engineering:
     At present, the application of LED in indoor lighting engineering is mainly concentrated in the field of commercial lighting, focusing on decorative lighting:
     1. Indoor and commercial atmosphere lighting for high-end specialty stores and shopping malls
     LED light source energy-saving and environmental protection, no UV, cater to the psychology of some businesses to display personalized light environment, has become the preferred source of light for some special products; the full spectrum of color range is very
     2, entertainment venues, beauty salon lighting
     LED integrated light source is easy to control with full color, can create static and dynamic lighting effects, from white light to any color of the full spectrum, rendering a strong entertainment atmosphere, the emergence of LED to this kind of space environment
     3. Atmosphere lighting in leisure places such as bars and cafes
     The LED light source is small in size and solid-state lighting, which gives the lamp manufacturer unlimited space to play. It can professionally produce all kinds of different styles of LED lamps, and the LED full spectrum of any color and dynamic and static lighting effects.
     4. Lighting of professional places such as museums and art galleries
     Museums, art galleries and other places belong to special occasions with high requirements for lighting environment. The special characteristics of the displayed items require that the illumination source does not contain ultraviolet rays and no heat radiation. LED is a cold light source, light
     5, commercial drama taste TV studio dance and photography stage lighting
     The application of LED light source in indoor lighting has explained a new concept to the lighting environment of the drama studio. The following are one of the award-winning projects for LED applications in 2005:
     As a first-class British TV station, GMTV changed the lighting of the studio to a color-changing LED last year. The energy utilization of lighting has been reduced by more than 60%, and the temperature of the studio has also dropped to a more comfortable level.
     6, hotel, hotel lighting
     The lighting of hotels and hotels uses LED products, or in the lobby, or in the guest rooms, to give customers a different feeling, in addition to saving energy, but also to show luxury and warmth, to the owners
     7, conference room, multi-function hall lighting
     The intelligent control LED is adjustable in grayscale, and the lighting environment of the conference room or multi-function hall can be adjusted according to the content of the conference. It can be set freely or lively. LED intelligent lighting can meet the requirements.
     8. Exhibition, fashion show lighting
     Exhibitions and fashion shows are places where merchants display their products and services. For merchants, in order to better attract customers, sell goods and finally reach a cooperation agreement, they need a personalized light environment.
     9, living room and home theater lighting
     The use of LED lighting colors to create a warm, harmonious, wave-temperate atmosphere, reflecting the comfort and leisure atmosphere. The application of LEDs explains another meaning for home lighting.
