(solar street lamps 。 jschindo。 com) In the aspect of energy conservation and environmental protection is developing rapidly. Light, usually refers to large lamp height of 15 meters or more. Wide application, it is an important part of urban public lighting system. As the cost of solar energy lamp gradually decline, more and more people begin to focus on solar energy lamp convenience, making some place to vigorously promote the use of solar energy lamp. In particular, high lamp powered by solar energy. Is not affected by power supply environment, not buried trench line, do not consume conventional electricity. As long as there is enough sunshine, it can be installed on the ground and will not pollute the environment. This conforms to the people in the pursuit of sustainable development. This kind of lamps and lanterns will be sought after by the people, its development prospect in the future will be very good. This kind of solar energy lights will replace traditional lighting, I believe it will be the future light, selling products, there will be a great development in the future. High pressure lamp and metal halide lamp is one of the most commonly used in high lamp light. Light utilization rate is very high, mainly reflected in two aspects: one is low price. Second, the radiation area is large, strong penetrating power. First of all, let's start with the price. In 20 meters pole lamp, for example. 20 meters high light pole should have at least 12 400 watts of light source can achieve good lighting effect. For example, many people said light-emitting diode lights save electricity, but lose electric high pressure lamp. 400 - watt leds and 400 w high pressure lamp is the same power, but power consumption is the same. In high lamp, for example, it almost is unqualified. Low power leds can replace high power lamp, because it can't meet dozens of meters of lighting conditions. The second is to light efficiency. High pressure lamp or metal halide lamp has a lot of advantages, namely the fog has a strong penetrating power. Careful friends may think fog lamps is metal halide lamp, or light source. Most high lamp installed in a main square or corner of the highway. In foggy weather, good lighting effect can reduce the number of traffic accidents. Therefore, high pressure lamp and metal halide lamp is two small advantage, is enough to gain a foothold in the lighting market, and it is not easy to be replaced by light-emitting diodes (leds) products.
