Solar street lights aren’t new products. Generally, the machine includes road lamps, solar panel, solar control, batteries, arm, pole, wires and so forth.
You might discover some jobs on town. They could save you all electricity resources and cost. It seems like great. You might think we ought to use Lichtmast anywhere. But why aren’t so common?
1. Why not so hot today
The principal reason is price. After the electricity consumption of road lamps is 60 Watt, it needs 150 – 170 Watt solar panel and 2 components 80 Ah batteries. The price tag is close USD 1, 000. If the energy consumption is greater, for example 150 Watt, the price will probably be somewhat amazing. Many nations can’t accept the cost. However, since conventional HPS street lights, the energy consumption is generally 60W, 80W, 150W, 250W or 400W. So, the price tag is high in many of cases. Many nations can’t accept the price.
2. LED technology
In the previous two decades, LED street lights eventually become increasingly more popular. They utilize LED (Light Emitting Diode) as light sources. Comparing with conventional HPS lamps, LED lamps may save 50%-70% energy. For instance, 30W, 60W, 110W and 160W LED lamps may substitute 80W, 150W, 250W and 400W HPS lamps.
3. Benefits of LED Street Lights
Main benefits are as follow
1). Lower power consumption
2). Greater power efficiency – LED street lights transcend mercury vapor’s 31 lm/W. You may find increased efficiency measurement from for high pressure sodium lamps. It’s merely misleading since it comprises wasted light that subsequently exerts energy. On the current market, much electricity efficiency of LED street lights may reach around 80lm/w.
3). More Lux Feb Watt – over twice that of a mercury vapor street light. The identical measurement for high pressure sodium lamps is due by hot areas that bulge up the lux score but trigger undesirable vulnerability, security and warmth issues.
