Moon Street light family is a solid design road lamp for our lovely city, the avatange is as following,
Long working life: as a solid-state light-emitting device, LED has a longer working life than other light-emitting devices. Its brightness half-life can usually reach 100000 hours.
Low power consumption: LED is a low-voltage working device. Therefore, under the same brightness, the power consumption is the smallest, which can greatly reduce the energy consumption. On the contrary, with the development of technology and materials in the future, it will have higher luminous efficiency. People have calculated that if all lighting fixtures in Japan are replaced by LED, two large power plants can be reduced, which is very beneficial to environmental protection.
Fast response time: LED can generally respond within tens of milliseconds, so it is a high-speed device, which is beyond the reach of other light sources.
Small size, light weight and resistance: These are the inherent characteristics of semiconductor solid devices.
In recent years, LED lamps have been widely used. What are the characteristics of LED street lamps and how should we correctly buy LED street lamps.
The difference between LED street lamps and conventional street lamps is that the LED light source adopts low-voltage DC power supply and high-efficiency white light synthesized by GaN based power blue LED and yellow. It has the unique advantages of high efficiency, safety, energy saving, environmental protection, long service life, fast response speed and high color rendering index. It can be widely used in roads. LED street lamps have no light diffusion to ensure lighting efficiency.
2. LED street lamps have unique secondary optical design, which irradiates the light of LED street lamps to the required lighting area to achieve the purpose of energy saving. The overall light efficiency of LED street lamps is stronger than that of high-pressure sodium lamps. LED street lamps can be used with lenses, which can flexibly control the illumination range and further improve the illumination efficiency.
3. The light color rendering performance of LED street lamps is higher than that of high-pressure sodium lamps. The color rendering index of high-pressure sodium lamps is only about 23, while the color rendering index of LED street lamps reaches more than 75. From the perspective of visual psychology, the illumination of LED street lamps can be reduced by more than 20% on average compared with high-pressure sodium lamps. Small light attenuation is also the advantage of LED street lamps. The light attenuation in one year is less than 3%, which still meets the road requirements after 10 years of use, The high-pressure sodium lamp has declined by more than 30% in a year. The design of LED street lamp in use power can be lower than that of high-pressure sodium lamp.
4. LED street lamps are equipped with automatic control energy-saving device, which can reduce power and save electric energy as much as possible when meeting the lighting requirements in different periods. It can realize humanized functions such as computer dimming, time-division control, light control, temperature control, automatic inspection and so on. Long service life: it can be used for more than 50000 hours and provides three-year quality assurance.
The light distribution of LED street lamps shall be considered in the selection of LED street lamps. Light distribution refers to the light intensity distribution of light sources (or lamps) in all directions of space. LED street lamps with the same power often have a wider irradiation range and more uniform light.
Furthermore, the light attenuation of LED street lamps should be considered. Generally speaking, light attenuation is that the light intensity of LED will be lower than the original light intensity after being lit for a period of time. There are two major problems affecting light failure: one is the poor quality of LED chips, and the other is the poor heat dissipation of LED chips. Therefore, LED chips shall be purchased from regular manufacturers as far as possible to slow down the light attenuation, and the heat dissipation of lamps is closely related to the structure of lamps.
