Solar energy lamps and lanterns of LE D street lamps are the three ways to reduce costs

Solar LED street lights are the three ways to reduce costs? Mainly include the following: 1. One by one to reduce the cost of the feasibility of the first is the optimal design. For solar cells, from 1980 ~ 2005, the efficiency increased by 3 ~ 4%, so improve the space is very



solar LED street lamp' Based energy as the earth's resources increasingly poor, the investment cost of the surging, all kinds of safety and pollution hidden danger is everywhere, the solar energy as an 'inexhaustible, an inexhaustible' safety, environmental protection, new energy more and more attention. 】 Are the three ways to reduce costs? Mainly include the following:

1. One by one to reduce the cost of the feasibility of

the first is the optimal design. For solar cells, from 1980-2005, increased by 3 ~ 4% efficiency, so improve the space is small, three years is expected to be 1 ~ 2%, and can reach 15-16% is very good. For the efficiency of the controller, the domestic excellent has reached 0. 975, abroad is 96%, nearly two years rise space is only 2-3%, could not have reached 99% and 100%. For the efficiency of lamps and lanterns, can use the power of the sun is low power, under 50 w. Domestic 50 w after sodium lamp test is 60 ~ 70%, energy-saving lamps, high pressure lamp and metal lamp, because there are electronic device of energy dissipation, tell the bad time is mostly electronic resolution is damaged, and the LED lamps and lanterns is except for this kind of light source.

　　2. With efficient leds can make than good lamps and lanterns?

the LED efficiency should be greater than 100 lm/W, and the efficiency of the constant current circuit to be greater than or equal to 90%, it is best to select booster, because the step-down ( DD311【 一般DescriptionDD311单一- 通道恒流驱动程序,它包含了电流镜andcurrent开关,用来驱动功率发光二极管。 它可以提供的最大反向电流1 a,可通过引用当前的输入。 输出电流输入当前值集的100倍是其外部电阻器或偏置电压。 的最大输出电压33 v可以提供更多seriespow。 。 。 】 DD322) The efficiency is greater than or equal to 80% of the chip. The newly launched several booster type, chip efficiency more than 93%. In addition to reducing the loss of backlight, because now a lot of lens is very poor, pervious to light material is different, some transparent lens than good, some of the transmission of light is very poor.

　3. LED lights the tender should be in power to offer

finally make a suggestion, the tender of the lamps in the future should be offer by power. Still need to find out its characteristic is to develop products. All above these applications in the solar system to encourage and encouraged development effect. Then there is solar LED street lamp for technical support, respect for intellectual property rights, products have commercial value, to achieve business results.
