This solar long-lasting illuminator uses sunlight as energy to charge during the day and automatically illuminates at night. It is safe, energy-saving and pollution-free. The process of charging and turning on/off lights is intelligently controlled by the microcomputer, and it has a working status display, no manual operation, stable and reliable. long lasting. Luminaires with high transparency sealed reflectors with IP65 protection. The lamp is equipped with photoelectric and thermoelectric dual system; the high luminous efficiency is used as the light source. The black light starts to work on the day, and automatically turns off after dawn. The whole lamp is very modern and practical, with high performance and price ratio. High-power high-end products in solar lamps. Continuous illumination for 3-5 days and lasts 7-10 days. At present, it can replace the high-pressure sodium lamp, which can be applied to the lane road. It is especially suitable for the remote and remote area of ​​the power grid. It is also suitable for lawn lighting and safety signage lighting with difficult wiring. It is green and energy-saving road lighting and urban landscape lighting.
1, working principle
According to the radiation heat transfer theory, all objects are constantly emitting radiant energy, while continuously absorbing radiant energy from other objects and converting it into electrical energy and thermal energy. According to the basic principle of organic combination of solar photovoltaic power generation and solar thermal power generation, an economical and practical energy technology has been overcome and a solar long-lasting illuminator has been developed.
1) According to the theory of radiant energy conversion, the concentrating and collecting device is used to absorb the radiant energy of the sun and convert it into electric energy and heat energy. Moreover, the higher the efficiency of the concentrating and collecting device, the more radiant energy is absorbed, and the greater the power generation and heat generation. According to this law, a new type of "solar lighting collector" was developed;
2) The sunlight is irradiated on the solar panel and the solar reflecting plate, and the solar reflecting concentrating groove that reflects the light converges the direct sunlight, and is corrected by the secondary reflector to reflect the parallel light to the solar panel. The light-receiving intensity of the solar panel is greatly improved, and the photoelectric conversion rate is increased by 40% or more.
3) Using the principle of solar thermal power generation to form a power generation system, using heat pipe technology to maximize the temperature difference in the solar collector, and then using the thermocouple thermoelectric power generation technology to form a power generation system. The heat collecting device is equipped with a thermocouple group, and the temperature difference potential is used for the photoelectric conversion system itself to increase the efficiency of solar power generation and prolong the lighting time. At the same time, the hot end of a part of the thermocouple is mounted on the heat sink of the illumination source, recovering thermal energy to generate electricity and cooling the light source (Peltier effect).
