Under normal circumstances, LED explosion proof lights, it can be said proof LED street light, LED explosion-road lights, street light is a dedicated LED explosion proof lights. LED street light is suitable for explosion-proof area outside the chemical explosive gases in hazardous environments for road lighting. LED street light from the explosion-proof lighting, electrical appliances, light, light pole, light arms, flanges, foundation embedded parts to form a whole. LED explosion proof lights by modeling sub-arm LED explosion proof lights, explosion proof LED lights arms. Proof LED street light with long life, low power consumption, high power factor, current harmonic content is small LED explosion proof lights. Yixing City Vantage Electric Manufacturing Co., Ltd. specializing in the production and sales of various power levels proof LED lights, LED street light proof, LED road lights explosion. The Company produced sales of LED explosion proof lights, there are two models available, the first one is BAD808-L series of multi-particulate street light special LED explosion proof lights, the second can also be used BAD808-L2LED series of LED square-proof floodlight . Since the development of the market as well as energy-saving lamps for the lighting industry and life become increasingly demanding, traditional street light proof has been unable to adapt to the needs of the market, it will gradually be eliminated, instead it is proof LED lights. So compared with conventional street light explosion, what the advantages of LED explosion proof lights have it? Prior to solve this problem, we need to look at the current status of road lighting. First, the status of development of explosion-proof lights LED street lighting at night when people have time to travel demand, giving rise to a road lighting. Modern incandescent lighting began to appear. With the improvement of road lighting is the development, scientific and technological progress and people's living standards and development. It only requires illumination from the road surface to detect the situation, to help people identify the road are pedestrians or obstacles, to help motor vehicles and non-motor vehicle drivers to identify pedestrians characteristics. The fundamental purpose is to provide street lighting for drivers and pedestrians good visual conditions, directing them to travel in order to improve traffic efficiency and reduce traffic accidents and crime at night while helping pedestrians to see the surrounding environment, a sense of direction. With the improvement of socio-economic development and people's living standards, people at night to outdoor recreation, shopping, sightseeing and other activities more and more, good lighting also play a rich life, the role of economic prosperity and enhance the city's image. In the view of the lighting, the road can be divided into four categories: car-only roads, generally streets, commercial streets and sidewalks. Often we speak of road lighting shall relate vehicle for road lighting. In many purpose road lighting, in order to provide a safe and comfortable vehicle driver visual conditions first. Road lighting was first street, then have appeared in high-pressure mercury lamp, high pressure sodium (HPS) lamps and metal halide lamps, energy efficient lamps, lamp and LED lights. In more mature street light, the light-efficient HPS lamp, generally up to 100 ~ 120lm / W, in the current Chinese entire road lighting market (has about 15 million), the HPS occupy more than 60% share . The lighting in some communities and rural roads are mainly electronic energy-saving lamps (CFL), accounting for about 20 percent of the road lighting market. Traditional incandescent and high-pressure mercury lamp, is gradually being phased out. LED lighting is an energy-saving lighting. LED road lighting demonstration is global expansion, China has become the pioneer in Taiwan in second place. In April 28, 2009, the Ministry of Science issued a formal [National Science High (2009) 189], in Tianjin, Shijiazhuang, Dalian, Shanghai, Hangzhou, Xiamen, Nanchang, Chengdu, Xi'an, Chongqing, Shenzhen, Dongguan and Shandong Weifang, and other 21 cities, "Ten thousand ten cities" pilot program, LED lights for its outstanding demonstration effect of various types of semiconductor lighting technology become a highlight. The second part focuses on the advantages we have to lower LED explosion proof lights, as well as some of the current problems. LED explosion proof lights advantages compared to high pressure sodium lamp as the representative of the traditional lamp, LED explosion proof lights has many significant advantages in and potential. (1) LED Explosion road lighting efficiency, low energy consumption of the current high-power white LED luminous efficiency more than 100lm / W, Cree (Cree), Osram (Osram) optoelectronic semiconductor companies such as high-power white LED laboratory level Back in early 2009 reached 160lm / W. According to the US Department of Energy (DOE) predicts that by 2020, the high-power LED commercial products luminous efficiency can reach 165lm / W, laboratory samples luminous efficiency can reach 230lm / W. After 2020, LED luminous efficiency will be greatly improved substantially longer, will enter a slow period. In terms of road lighting, high pressure sodium lamp as the luminous efficiency can reach 120lm / W and dominant. However, with the continuous improvement of LED luminous efficiency, high pressure sodium lamps monopoly stake. On secondary roads currently used following 150W LED lights, already reflect the significant energy-saving advantages. Traditional street light to the entire space is generally light, but requires only traffic lights to illuminate the road and pedestrian, so the street lighting design, in order to make as much as possible and focus light uniformly projected onto the road, you need to use the reflector surface collect light, so that it impinges in the direction required. In the light of the communication process, due to the absorption of light blocking and reflective surfaces of the loss, resulting in street light efficiency is only 65% ??to 70%. In contrast LED lights, because of its good directionality, when using secondary optical lens, lighting efficiency up to 80%. If then three times optical design, the light fixture efficiency up to 85% to 90%. Table 1 shows a 400W high pressure sodium compared with a light efficiency of LED street lamps and road utilization and other parameters to 250W. Table 1400W HPS and 250W of LED lights parameters between proved replace high pressure sodium lamps used on secondary roads 250W light distribution of scientific and reasonable 100W LED street light, not only to achieve the average intensity of road lighting standards, and uniformity It has also been greatly improved. The local average illuminance area high pressure sodium lamps may be high, but the uniformity was poor. Thus, LED lights with considerable saving of space. High-intensity discharge (HID) lamp lights, dimming generally only in a small area, and LED lights dimming control can be achieved from 0% to 100% range, the light output can be flexibly adjusted according to the ambient lighting and traffic conditions, reduce unnecessary power consumption in ensuring the lighting needs of the situation. Thus, for the total lighting electricity consumption is about 15% to 20% of road lighting, the large-scale implementation of LED lights for energy-saving carbon reduction is important. (2) LED explosion proof lights long life street life is directly affecting the maintenance cost of the entire road lighting. Currently HPS life is generally about 20,000 hours, high pressure sodium lamp street lighting life of only about 5000 hours, and high-power LED life is generally up to 5 to 70,000 hours. HPS and LED average life is defined differently. HPS average lifetime is defined as "the number of samples tested ignition source to the time when 50% of the amount of damage", while the average life expectancy of LED refers to "the number of test samples to 50% light amount of the light fades to 70% of the time. " If life is defined by high-pressure sodium to measure LED, life of 50,000 hours of LED is up to 100,000 hours; if by LED lifetime is defined to measure high-pressure sodium lamp life of 20,000 hours of high-pressure sodium lamp only about 10,000 hours. Of course, LED's life is not the life of LED lights. LED street lamp life is life and life LED light source driving circuit common decision, and the life of LED and driver circuit depends on the cooling capacity, the circuit structure and topology selection lighting electronic components variety of factors. Look from the current level of technology, LED street life can be more than high-pressure sodium lamps. (3) LED explosion proof lights color is good, although the highest luminous efficiency of traditional high pressure sodium light sources, but its worst color, color rendering index Ra is only about 20. Such poor color rendering can only help people perceive road conditions, and can not help pedestrians clearly identified. The LED color rendering index of 80 or so, basically close to natural light, the color rendering is more real, more able to reflect the color of the object itself. LED of high color will undoubtedly help drivers and pedestrians recognize the goal of providing better traffic conditions at the same brightness pavement. (4) LED explosion proof lights quick start incandescent point that light, but in fact the start-up time of approximately 0.1 to 0.2 seconds. Only start after high-pressure sodium and metal halide discharge lamp from start to stable light output than a minute out of time even after shutdown to wait 3 to 6 minutes to cool. The LED start-up time of only several tens of nanoseconds (ns), there is no waiting time to restart, LED lamps can work in a continuous on / off status. (5) LED explosion proof LED lights to facilitate optical design, small size, can be directional light in the upper half plane, the lighting design can be considered a point source approximation is very suitable for the use of lenses or reflectors for optical design, get comparison ideal light, to achieve high efficiency lighting. (6) LED explosion proof lights modeling plasticity, solid structure LED street lamps in the shape of plasticity, may be embodied in decorative and local cultural characteristics through design, adding additional value beauty and city image. LED is a solid-state light source, and the filament-free glass and other fragile parts. LED lighting through rational design, the structure can be very strong. (7) LED explosion proof lights low-carbon environment, especially for the use of solar photovoltaic technology and other high-pressure sodium discharge lamps contain mercury and other harmful substances, waste on the environment and water sources cause serious long-term pollution. LED chip and packaging to meet the EU RoHS directive, mercury and lead and hazardous substances. LED rear waste can be recycled, do not pollute the environment. LED DC drive of the characteristics, especially for the use of solar photovoltaic technology and wind and solar technology for road lighting, in order to achieve energy saving lighting in the true sense. (8) LED explosion proof lights have a total potential cost advantages now LED street lamps unit price is higher than the high pressure sodium lamps more than 4 times. An effect equivalent to 250W of LED lights 400W high-pressure sodium lamps, but the former price of 6,000 to 8,000 yuan, which is only 1,500 yuan. However, LED lights high luminous efficiency and long life as long as possible to give full play to the characteristics, can rely on savings in electricity and maintenance costs to recover the initial cost difference. With the maturity of LED lamp technology and continue to lower the initial cost, its potential advantages in total cost will not take a long time to emerge. Three, LED lights present problems though LED lights and traditional lights have some comparative advantages, but due to the development of LED lights for a short time, is still in the experimental and exploratory stage, there are a number of LED lights there have been many problems in an exemplary application, and it did not live up to the desired effect. LED lights currently exist in varying degrees of problems as follows: (1) Actual luminous efficiency is lower than the high-pressure sodium lamps, the lighting effects in low surface brightness, uniformity is poor, "zebra effect" obviously, can only meet the lighting level is low roads, such as poles at 8 meters below the secondary roads. (2) Color temperature is too high, glare-free comfort (3) thermal performance is poor, temperature is too high, resulting in a more serious light fades, reliability deteriorates. (4) drive power performance is poor, failure after another, from the case of early LED lights failure, there are more than 95% of failures are caused by damage to the drive circuit. (5) The cost is too high, one-time investment too, has become a major bottleneck in the promotion of applications. (6) Since there is no uniform standard LED lamp technology, products from different manufacturers Universal very poor, very difficult to maintain. The reason for these problems are many factors on both the technical level, but also affect the mindset and so on. Indeed, LED lights is a systems engineering. Since the LED light source and high pressure sodium lamp fundamentally different, in the design method LED lights and traditional lights it is different. In addition to the design experience designer lamps, LED performance also need to have a comprehensive and in-depth understanding. Some manufacturers in the street are not yet understood LED road lighting production requirements and characteristics of the case, follow the traditional design ideas to design LED street lights, in the shape still using conventional "snakeheads" form, to apply the concept of a gas discharge lamp, as long as A certain power LED emissions in the socket on the road to meet the lighting requirements. According to this thinking design and manufacture of LED lights, impossible practical use. Compared to traditional explosion-proof lights, LED explosion proof lights LED light source in short, there are some of the following features. 1, features LED lights themselves - one-way, no light diffuse light and ensure the efficiency of light. 2, LED lights have a unique optical design, LED lights will light shines on the desired area lighting, and further improve the efficiency of light in order to save energy. 3, LED light source efficiency reached 110-130lm / W, but there is still much room for development, the theoretical value of 250lm / W. High pressure sodium lamp luminous efficiency is increased with the increase in power have, therefore, the overall luminous efficiency LED lights stronger than high-pressure sodium; (the overall light efficiency is theoretically, in fact, more than 250W high pressure sodium lamp luminous efficiency is higher than the LED) . 4, LED street light color than high pressure sodium lamp many, high pressure sodium lamp color rendering index of only 23, while the LED lights color rendering index of 75 or more, from the viewpoint of visual psychological point of view, to achieve the same brightness, illumination LED lights mean you can lower than the high pressure sodium lamp more than 20% (see the British lighting standards). 5, light is small, light failure a year less than 3%, with 10 years still to reach road use illumination requirements, and high-pressure sodium light fades large, about a year has fallen by more than 30%, therefore, LED lights in the use of power the design can be lower than the high pressure sodium lamps. 6, LED lights with automatic control energy-saving devices, can be implemented in time to meet the lighting requirements of different circumstances the maximum possible reduction in power and save energy. Spark LED lights can achieve computer intelligent dimming control sub-period, light control, temperature control, remote control, automatic inspection and other user-friendly features. 7, LED are low voltage, single LED drive voltage is safe voltage, series single LED power is 1 watt, so it is a more secure than the use of high voltage power supply, especially for public places (for example: street lighting, industrial lighting, automotive lighting, commercial lighting, etc.). 8, each LED die unit only a small volume, it can be prepared into various shapes of devices, and for the environment variable. 9, long life: can be used for more than 50,000 hours, provide three years of quality assurance. Deficiencies is the power of life can not be guaranteed. 10, high luminous efficiency: using ≥100LM more chips, as opposed to traditional high pressure sodium lamp can save more than 75%. 11, installation is simple: no Jiamai cable without rectifiers, etc., directly to the street light poles installed in or connected to the original light source nested shells. 12, excellent thermal control: summer temperature at below 45 degrees, and the use of passive cooling, lack of summer heat protection.
