Generally used to evaluate LED lighting systems, they are often inspected in terms of reliability and service life, especially in the introduction of street lamp-type public facilities. In order to achieve low power consumption LED light source street lamp facilities, LED components, lighting The control system and lamp design, the overall structure need to meet the requirements of high reliability and high luminous flux output.
The design of LED street light is not as simple as the home lighting source, because the use environment of LED street light is relatively harsh, and it needs to be able to withstand strong wind and large temperature difference between morning and evening. In order to achieve the luminous efficiency of the lighting purpose, the luminous efficiency of the components has high luminous flux requirements. It's just that the lighting system itself needs to meet the design requirements, and the matching drive circuit, lamp housing, heat dissipation design, etc., must be matched to meet the final product review requirements in order to achieve the design goals of high reliability and long service life.
Safety performance comparison: The current high-pressure sodium lamps and mercury lamps on the market use high-voltage point poles to excite X-ray illumination, which contains harmful metals such as mercury, and harmful rays; in contrast, LED street lamps are safe and low-voltage products. The safety hazard is greatly reduced in the process of use and use.
Electricity cost comparison: The electricity cost of using 57W LED street lights in a year is only 20% of the electricity cost of using 250W ordinary high pressure sodium lamps in a year, which greatly saves electricity costs. It is an ideal energy-saving and consumption-reducing product, and it also conforms to the construction of a conservation-oriented society. the trend of.
Environmental protection performance comparison: Ordinary street lamps contain harmful metals, and the spectrum contains harmful rays. In contrast, LED street lights have a pure spectrum, no infrared and ultraviolet rays, no radiation, no light pollution, no harmful metals, and waste can be recycled, which is a typical green lighting product.
Comparison of service life and quality: The average service life of ordinary street lights is 12,000 hours. Replacement of street lights is not only costly, but also affects traffic. Construction in tunnels and other places is especially inconvenient; the average life of LED street lights is more than 50,000 hours, calculated as 10 hours of use per day , The service life is more than ten years, once and for all.
Traditional road lighting uses high-pressure sodium lamps. The lifespan of high-power LEDs is generally 50,000 to 70,000 hours, while the lifespan of general high-pressure sodium lamps is about 20,000 hours, and the lifespan of high-pressure sodium lamps for road lighting is only about 5,000 hours. The life of the LED light source and the life of the drive circuit jointly determine the life of the LED street lamp. The life of the LED is not equal to the life of the LED street lamp, but from the current technical level, the life of the LED street lamp can exceed the service life of the traditional high pressure sodium lamp street lamp.
