How much is the lamp1

Today, solar street lamp manufacturers share three ways to reduce the cost of solar street light. In order to reduce costs, and only three methods. First is to optimize design in order to improve the efficiency, the second is to change the configuration to reduce costs, the third is to improve the luminous efficiency and reducing power consumption



today, solar street lamp manufacturers share three ways to reduce the cost of solar street light.

in order to reduce costs, only the three methods. First is to optimize design in order to improve the efficiency, the second is to change the configuration to reduce costs, the third is to improve the luminous efficiency and reducing power consumption.

1。 The first is to optimize design. For solar cells, from 1980 to 2005, the efficiency increased by 3% to 4%, thus improving the space is very small. Is expected within three years from 1% to 2%, from 15% to 16% as well. For the efficiency of the controller, excellent domestic reaches 0. 975, the foreign outstanding up to 96%. In the past two years, to improve the space is only 2-3%, could not have reached 99% and 100%. In order to improve the efficiency of lamps and lanterns, solar power is low power, less than 50 w. Domestic 50 w after sodium lamp test is 60 ~ 70%, energy-saving lamps, high pressure lamp and metal lamp, because of the energy consumption of the electronic discriminator, most of them are electronic rotating transformer in the bad time is damaged, and LED lamp is the light source.

2。 For several low cost configuration, when resource cost is low, the solar cell configuration is reasonable, but the experimental value is very small. When people leave the lighting, electricity storage part is small, light less than eight hours a day. The second is the solar cell is very small, controlled battery is very small, there is no guarantee that every day. The third aspect is solar battery small and large. Although can't power can guarantee 10 days before the day, but it will be very bright, but in fact it is battery power. The fourth is high power, low configuration. Although the light, but eight hours cannot be guaranteed.

3。 System design space is very small, low cost control will affect the quality. Traditional light source in the past two or three years will be increased, the conclusion is that traditional technology and greatly reduce the cost of the solar system. So what is the design concept? It is in order to improve the light efficiency, this is just mentioned a third option. Improve the luminous efficiency is equivalent to reduce power. Reduce power equivalent to reduce the cost. Therefore, to improve the LED luminous efficacy is another way to reduce costs. From the point of view of network engineering, on the basis of 70 lm/w, LED luminous efficiency increased by 15%, the solar energy cost can be reduced by 10%. Increase the photosynthetic efficiency has little impact on the system, because the lighting quality did not reduce, the total drive almost the same amount, solar energy costs significantly reduced, less battery, battery support, maintenance and panels are reduced. As long as control the cost of high efficiency LED, it accounts for 15% to 10% of the total cost. If you want to choose LED, same = the same lighting lighting power, which is 1 w = 320 yuan, you have to reduce the power! According to the test of different LED both at home and abroad, although the luminous efficiency of 100 lm/W, but the strain of illuminance solar LED street lamp is 30 ~ 40%, the so-called value.
