As the world energy crisis intensified, people discovered and used solar energy. As an environmentally friendly and safe energy source, solar energy has attracted more and more attention. At this time, the development of 15 watt solar street light in the field of lighting has become increasingly perfect. Solar street light is powered by crystalline silicon solar cells, maintenance-free valve-controlled sealed batteries (Gel Batteries) store electrical energy, ultra-bright LED lamps are used as light sources and be controlled by intelligent charge and discharge controllers, which are used to replace traditional public power lighting. So what are the basic knowledge of solar street light? The following is the sharing of the editor of Second Sun Lighting:
There are many types of solar lights wholesale. According to the light source, they can be divided into LED lights, solar street light, and energy-saving solar street light. According to occasions, they can be divided into ordinary solar street light, high pole solar street light, courtyard solar street light, landscape solar street light, etc.
The street light spacing is jointly determined by various factors such as the lighting power of the street lamp, the height of the street lamp, and the width of the road. The distance between street light is generally 3.8~4 times the height of the poles. The longitudinal spacing of street light is generally 30~50 meters, and when there are power poles or other electrical pole, the spacing is 40 meters to 50 meters. Try to combine power supply poles with lighting poles to save investment. Cables are used for power supply if underground, the spacing should be small which is conducive to the uniformity of illumination, it is usually 30~40 meters.
China solar lamp sources with solar power system include LED lights, induction lamps, ordinary energy-saving lamps, metal halide lamps, etc. Which street light source is better? The cost of metal halide lamps and ordinary energy-saving lamps is not high, the life is long, and maintenance is convenient. However, this kind of street light source consumes relatively high electricity and is not recommended. Induction lamps are also a kind of energy-saving lamps, and their theoretical life is quite long, but the cost is high and difficult to maintain, this type of light source is not recommended; street lamp LED light source is the most used light source in recent years, high efficiency, energy saving, environmental protection, long life, easy maintenance, and the price is not expensive, and many countries and regions are vigorously Promote LED, street light source selection recommends LED, LED solar street light is the best choice for road lighting.
The height of customized commercial solar street lights (street light pole height) included 4m, 5m, 6m, 8m, 10m, etc. The specific usage of street light height should be based on the width of the road surface. Generally, the height of the street light is the same as the width of the road surface, or the height of the street light is less than 1m of the width of the road. The relationship between common LED street light power and lamp pole height is generally: 30~60W of street light height below 6m, 60~100W of street light height below 8m, and 100~150W of street light height below 10m.
The solar panels should be facing the direction of the sun with the most sufficient sunshine time. Generally, the solar panels face the south in Central & South of China, and the solar panels face 5 degrees west of due south In West & North of China. It should be noted that the direction of the solar panels can be adjusted appropriately according to the shelter of buildings or trees, within 20 degrees to the west or east (the effect of the west is better than the east).
