Lighting: What are the advantages of LED landscape street lights applied to street lights

The LED street lamp with a special light shape design is applied to the street lamp luminaire, which can offset the luminous angle of the luminaire and improve the utilization rate of roadside lighting; according to the rectangular aspect ratio, it can produce an aspect ratio of 2:1 Light spot, so that there will be no shadows between adjacent light spots, and a bright light band with uniform illuminance can be formed on the road, which is more in line with the current lighting design of traffic roads. It is sufficient to meet the needs without raising the height of the light pole. Wide illumination range, but also improve the lighting efficiency of the lamps and reduce the lighting power density of the road, so as to truly achieve energy saving and green environmental protection. Use high-power LED street lights for road lighting. The following landscape lighting manufacturers will share the LED landscape for everyone Compared with traditional high pressure sodium lamps, street lamps have incomparable advantages: u003cbru003e u003cbru003e u003cbru003e u003cbru003e u003cbru003e u003cbru003e 1. The light-emitting mechanism is different. Because LED street lights are semiconductor devices, their effective life can reach 50,000 hours (that is, the light attenuation is less than 30% after 50,000 hours), which is much higher than sodium lamps and metal halide lamps (they The life span is about 12000-15000 hours). u003cbru003e u003cbru003e u003cbru003e u003cbru003e u003cbru003e u003cbru003e 2. Since the LED street lamp is a semiconductor material, there is no filament or other additional materials, so it has good shock resistance. u003cbru003e u003cbru003e u003cbru003e u003cbru003e u003cbru003e u003cbru003e 2. The color rendering index of LED street light source lighting can reach above 80, which is relatively close to natural light. In this case, human eyes can distinguish things more easily, which is beneficial to driving safety; while the color rendering index of high pressure sodium lamps is only 20- 30. u003cbru003e u003cbru003e u003cbru003e u003cbru003e u003cbru003e u003cbru003e 3. Traditional gas discharge lamps such as high-pressure sodium lamps have a preheating process when starting, which wastes energy and is not conducive to intelligent control; LED street lamps are essentially different in light sources, so there is no 'start-up time' 'The problem is that it can work normally immediately after power-on, which can easily realize intelligent energy-saving control. u003cbru003e u003cbru003e u003cbru003e u003cbru003e u003cbru003e u003cbru003e 4. Since traditional street light sources use mercury vapor mechanism to emit light, the disposal of waste light sources is also an urgent problem to be solved in the world. At the same time, the light-emitting mechanism of traditional light sources determines that it will emit light that is harmful to humans. Of ultraviolet rays. The LED street light source is solid-state lighting, there are no harmful substances such as mercury and other elements, and it does not emit ultraviolet rays, so it is an environmentally friendly light source. u003cbru003e u003cbru003e u003cbru003e 5. In the optical system, the traditional street light source emits omnidirectional light, half of the light needs to be reflected by the reflector, and the reflector needs to absorb part of the light, so the light loss is relatively large. Since LED street lights emit light in one direction, the utilization rate of light is higher than that of traditional street lights. u003cbru003e7. The light distribution curve of the traditional street lamp is determined by the reflector, so it has certain limitations, while the LED street light source is a distributed light source. The design of each electric light source can make the light source of the lamp ideal Batwing shape, through reasonable control of the light distribution, the road surface spot is rectangular, and a higher uniformity of illuminance is obtained within the effective illumination range. u003cbru003e u003cbru003e u003cbru003e u003cbru003e u003cbru003e u003cbru003e 8. More complete automatic control (optional): Different brightness can be set according to the needs of different time periods, which further improves the effect of energy saving. For example, the brightness is 200W at 7 o'clock in the evening, and when there are few people at midnight, the brightness is automatically adjusted to 100W, which can also save 60W of power. u003cbru003e u003cbru003e u003cbru003e u003cbru003e u003cbru003e u003cbru003e In the current TD lighting design, the lamp distance is generally 3 times the lamp height, and the lamp height is generally equal to the road width. According to the geometric triangle relationship, the light distribution angle of the lighting fixture can be calculated as C0/180 direction About 140 degrees, C90/270 direction is about 80 degrees. In the past 100 years, the lighting source has gone through three important stages: incandescent lamps, fluorescent lamps, high-intensity discharge lamps (HID). The promising LED street light source is called the fourth-generation light source. As an emerging light source, LED street lights have long life, high luminous efficiency, low power consumption, short start-up time, high color rendering index, low working temperature, firm structure, no fear of vibration, good directionality, low working voltage, no UV It is a new generation light source with the most development potential in the world with its remarkable characteristics such as radiation and light weight. Moreover, the LED street light source can realize mercury-free production, which is also of great significance to environmental protection. Solid-state lighting lamps that use semiconductor LED street lamps as light sources will gradually replace traditional lighting lamps and enter various application fields. u003cbru003e u003cbru003e u003cbru003e u003cbru003e At present, lighting consumption accounts for about 20% of the entire power consumption, and greatly reducing lighting power consumption is an important way to save energy. LED street lights are attracting the world's attention with their solid advantages. The United States, Japan and other countries and Taiwan have predicted the benefits of LED street lighting. 55% of the incandescent and fluorescent lamps in the United States are replaced by LED street lights, which can save 35 billion U.S. dollars in electricity bills and 755 million tons of carbon dioxide emissions each year. Replacing 100% of Japanese incandescent lamps with LED street lamps can reduce the power generation of 1-2 nuclear power plants and save more than 1 billion liters of crude oil consumption every year. In Taiwan, 25% of incandescent lamps and 100% of fluorescent lamps are replaced by LED street lamps, saving 11 billion kWh of electricity each year. LED street lighting will also form a huge industrial market of 50 billion US dollars. u003cbru003e The above is all the content shared by landscape lighting manufacturers for your reference only.
