solar led street light [ 。 jschindo。 com] The basic principle of automatic lighting system is under the condition of light, solar panels convert light energy into electrical energy to the battery charging, and electrical energy stored in the battery. Power in a night, battery charging and light, make the semiconductor light-emitting diodes. System adopts fully automatic working mode, without human intervention, can use sound, light, or delay control mode & other lights, when the lights went out. ( Refers to the corridor, corridor, etc. ) 。 ) Or & other dark when it opens, after a while it to turn off the lights. ( Refers to the roads, gardens, scenic spots, etc. ) 。 ) Or 24 hours a day Chang Ming never & death; ( Refers to the underground parking lot, tunnel, etc. ) For the continuous rainy days, the system can be set according to the number of days ( 5 - 7 days) Normal work. Shandong street lamp lighting factory co. , LTD is a company specializing in the production of solar street light, high lamp, garden lamp, landscape lamp, led street light. It has more than 15 years of production experience, high quality, low price and honesty. Welcome new and old customers to come to consult. Pv power generation principle of the photovoltaic effect. For crystalline silicon solar cells, the open circuit voltage of a typical value is 0. 5 - 0. 6 V。 Electronic - produced by the lighting on the interface layer More than 1 strikes with empty holes, the greater the current. Interface layer to absorb the light energy, the formation of the current. At present, the main application and research of solar cells including silicon solar cells, compound semiconductor and dye-sensitised solar cells battery. Silicon solar cell is the mainstream of solar photovoltaic cells. In silicon solar cell, monocrystalline silicon solar battery photoelectric conversion efficiency is especially significant, laboratory conversion efficiency of 24% or more, the industrial scale production of monocrystalline silicon solar cells reached more than 18%. Thin film solar cells has a great development. Polysilicon/microcrystalline silicon thin film solar cells such as the new solar cells have also been large-scale industrialization, conversion efficiency of 16% or more. In recent years, the CIS, CIGS thin film solar cells and GaAs solar cell compound semiconductor solar cells research has made real progress. Dye-sensitised solar cells research has made significant progress. Photovoltaic technology and led lighting is the key to perfect combination, both are DC, low voltage, can match each other. Therefore, a combination of both do not need to convert solar cells produce direct current into alternating current (ac), thus greatly improving the efficiency of the entire lighting system. At the same time, with the aid of grid technology or battery charge and discharge energy, its advantage is more obvious. With the in-depth study of related technology, constantly improve the luminous efficiency of light-emitting diodes, high brightness leds will appear, this will replace the ordinary light source, saving a large amount of energy, no pollution. Work because of the light emitting diode for DC current, low voltage. The solar cell can convert light energy into direct current, the solar cell module can be needed for the series and parallel to get the actual voltage. These features exactly match the light-emitting diodes (leds). The combination of both will achieve high energy efficiency, high safety and reliability, to achieve energy saving, environmental protection, safe and efficient lighting system, realize a perfect combination.
