  • Description: Background introduction of the lighting system of Led Street Light Factory: In order to meet the urban road lighting design standards, traditional street lamps often use mercury-containing bulbs over 200 watts. In contrast, by 2009, the light efficiency of light-emitting diodes (LEDs) on the market had exceeded 100lm/w. This means that using LED as the light source will greatly reduce power consumption. Due to the long service life of LEDs, mercury-free and energy-saving features, it is a good choice to use LED lighting instead of traditional LP (low pressure sodium lamp) or MH (metal halide lamp). At present, the wholesale led street lamps have been tested in various countries around the world. In order to solve the problem of energy shortage and greenhouse gas emissions, led street lights have been used in many places, including some regions and city governments in China, North America and Europe. Since most of the LEDs on the LED street lamp factory market are Lambertian (Lambertian distribution) distribution, the central light intensity, and the symmetrical circular spot distribution, can not be directly used for road lighting. In addition, the quality of the optical design directly determines the efficiency of LED street lights. Some LED street lamps are coupled with poorly designed secondary lenses, and some light in the lens may be lost after multiple reflections or cannot be matched to the effective area. There are about two lenses. Although the shape and uniformity of the dots can be obtained, the light efficiency is reduced by nearly half. In addition, the quality of the optical design is also set without glare, and some lens designs are poor. Although it can also produce a rectangular, uniformly distributed light spot, the distribution curve can also be a bat wing, but the failure to use the cut-off light design leads to the direction of the road Light or a lot of radiation in the range of 75~90, which will cause glare to vehicles or pedestrians in the distance. A good optical design should take full advantage of the small area of ​​the LED light source, and fully consider the use of light. All light is distributed from the LED chip to the road, forming a good uniformity, no glare, and the light distribution curve is a bat wing point. LED street light factories are required to overcome the problems technically.
