Debate on the advantages and disadvantages of LED street light LED as a new type of light source, application scope is more and more widely, also gradually to cause the attention of more people and expectations. In the 21st century, the emergence of the LED will cause a revolution in the lighting industry. Now LED application in various industries, including instructions, display,

debate about advantages and disadvantages of LED street light as a new type of light source, light-emitting diodes (leds) has been more and more widely used, and gradually attracted more and more people's attention and look forward to. In the 21st century, the emergence of the light-emitting diode will bring a revolution in lighting industry. At present, the light-emitting diodes (leds) used in various industries, including display, display, decoration, lighting, etc. Lighting is the most potential, used the largest number of industries. With the constant improvement of the efficiency of led lighting and continuously reduce costs, its market share in the whole lighting area will also be growing. A few years ago, China set up a state-level light-emitting diodes (leds) project team, integrate resources, quickly led to the lighting market. According to forecast of the Chinese Academy of Engineering, 10 years, China can save 400 billion kilowatt hours of electricity, save electricity, 260 billion yuan for the user, create output value 150 billion yuan, 1 million people obtain employment problem. Semiconductor lighting will each year than the 'big MAC' ( The three gorges power station power generating capacity) Save more power! Under the background of growing energy shortage, the development of led lighting is the government's use of energy-saving features of light-emitting diodes (leds) build a conservation-minded society's positive response. However, from the point of actual appearance, every coin has its two sides. Let's discuss the advantages and disadvantages of LED street light. First of all, the led as lighting source has the following advantages: 1. Flexible size and shape, can combine with building, to achieve the effect of light not light; 2. Low power consumption: for 75 mm/w leds luminous efficiency is lower than the same brightness of incandescent lamp power consumption by about 80%; 3. Long service life, the service life of the product for up to 50000 hours, 24 hours continuous lighting up to seven years. 4, the environmental protection: no harmful metallic mercury, no infrared and ultraviolet radiation; 5. Brightness and color of the dynamic control is simple: the brightness of continuous adjustment, high purity of color, can realize the dynamic transformation and digital control of the color; 6. Color: bright, saturation, pure, do not need to filter, red, green, blue three kinds of elements can be adjusted according to different color, can achieve variable, variable, and mixed lighting effects, excellent color rendering effect. So much advantage makes us feel vigorously promote the use of the combination of light-emitting diodes (leds) is a valuable work. Second, the solar street lights and led as lighting source has the following disadvantages: however, compared with other light source, leds also has some disadvantages, such as low color of white light illumination. At present, made of yellow phosphor and blue color rendering index of white light leds is about 80. It can be used as a general lighting, but for some of color resolution demanding place, it is not enough. Although by adding the appropriate methods such as red phosphor color rendering index can be increased to 90 or higher, but compared to the incandescent light bulb 99 still has certain gap, its efficiency will be affected. Through the RGB color mixture can also improve the color, but in popularization and application of technology there is more work to do, so the LED needs to be improved in terms of color rendering. In terms of street lamp manufacturers in shandong, although the LED street lamp of the initial investment is larger, but after a street lamp installation and debugging, the light brightness, later maintenance costs and cable laying cost is far lower than the traditional sodium lamp light source. State advocates the use of led street light, in the hope that the general technical staff efforts, make the led street lamp is widely used.
