Description of Solar Street Lights

Description of solar street lights 1. Advanced product technology The company has established long-term close cooperative relations with many colleges and universities in China and many authoritative scientific research institutions and experts, and the research and development of solar photovoltaic lighting products has reached the domestic leading level in this field. Dedicate to the society new high-level lighting products that are safe, practical, economical, low-cost, reliable, safe and convenient, long-life and maintenance-free. Solar street lights have a number of mature technologies or patents: 1. High-power LEDs have been developed as light sources, with a single 30-70W. It completely solves the problems of difficult heat dissipation, short life and poor performance caused by multi-particle assembly. 2. Matching solar panels, the quality is superior and the effect is more outstanding! discount price. 3. Developed a new light source - xenon lamp (the so-called car headlight), which has high brightness, less heat dissipation and stable performance. 2. Wide application range The solar photovoltaic lighting lamps developed by our company have been formed into lawn lamps, garden lamps, road lamps, landscape lamps, high pole lamps, underground lamps, spotlights, corridor lamps, advertising lamps, and architectural outline lamps. Ten categories of serialized products. It is widely used in lighting decoration and lighting in cities, parks, residential quarters, schools, squares, buildings and green spaces. The company's solar photovoltaic lighting series products can provide a variety of design solutions according to the different needs of users and the actual situation of the site. Allow users to have ample choice. Satisfy user needs and satisfy users. 3. The main performance and characteristics of the product 1. The solar photovoltaic modules made of international famous brand originals have a service life of more than 20 years. 2. Equipped with a special light source light bulb with a unique device, the service life is > 20,000 hours. 3. Special microcomputer automatic control system, automatic detection, adjustment, charging control and protection system; light control, voice control, time control, induction control, far-infrared control system and backup power supply automatic starting system. 4. Predetermined or specially set lighting time, brightness and light color control system. 5. High-capacity maintenance-free battery can be designed with 1 to 10 times the power reserve according to customer requirements. 6. The lamp pole, bracket and lamp head are treated with anti-oxidation and anti-corrosion, and the lamp cover is made of specially processed tempered glass. Strong environmental adaptability, anti-frost, anti-ultraviolet. It can work normally in the temperature range of -25 degrees Celsius to 55 degrees Celsius and humidity <85%. 7. The installation is convenient, and the structural connection uses standard parts. There is no external circuit connection, and it is directly installed on the ground without digging trenches and special wiring. 8. Work below the safe voltage, no electric shock accident will occur. One-time investment and installation, long-term benefits, and no need to pay electricity bills. 9. The lamp is controlled and managed by a microcomputer single-chip microcomputer, no special person is required to manage the power transmission, and there is no need to replace the light bulb frequently. Fourth, high-quality, efficient and comprehensive after-sales service Principle of solar power generation The solar power generation system consists of solar battery packs, solar controllers, and batteries (groups). If the output power is AC 220V or 110V, an inverter is also required. The functions of each part are: (1) Solar panel: The solar panel is the core part of the solar power generation system and the most valuable part of the solar power generation system. Its function is to convert the radiation capacity of the sun into electrical energy, or send it to the battery for storage, or drive the load to work. The quality and cost of solar panels will directly determine the quality and cost of the entire system. (2) Solar controller: The function of the solar controller is to control the working state of the entire system, and to protect the battery from overcharge and overdischarge. In places with large temperature difference, a qualified controller should also have the function of temperature compensation. Other additional functions such as light-controlled switches and time-controlled switches should be optional on the controller. (3) Batteries: generally lead-acid batteries, nickel-metal hydride batteries, nickel-cadmium batteries or lithium batteries can also be used in small and micro systems. Its function is to store the electrical energy emitted by the solar panel when there is light, and release it when needed. (4) Inverter: In many occasions, it is necessary to provide 220VAC, 110VAC AC power. Because the direct output of solar energy is generally 12VDC, 24VDC, 48VDC. In order to provide power to 220VAC electrical appliances, it is necessary to convert the DC power generated by the solar power generation system into AC power, so a DC-AC inverter is required. In some occasions, DC-DC inverters are also used when loads with multiple voltages are required, such as converting 24VDC power into 5VDC power.
