What is the working principle of solar landscape lamp?
Solar landscape lamp uses solar power generation as power supply to provide road lighting at night. It adopts high luminous efficiency lighting source design and light control plus time control. It has the advantages of high brightness, simple installation, stable and reliable operation, no cable laying, no consumption of conventional energy and long service life. It is a green energy product strongly advocated in today's society.
Solar panels are devices that respond to light and can convert light energy into electrical energy. There are many kinds of materials that can produce photovoltaic effect, such as monocrystalline silicon, polycrystalline silicon and so on. Their power generation principles are basically the same. Now take crystal as an example to describe the process of optical power generation. P-type crystalline silicon can be doped with phosphorus to obtain n-type silicon and form p-n junction. When
the light shines on the surface of the solar cell, some photons are absorbed by the silicon material; The energy of photons is transferred to silicon atoms, making electrons transition and become free electrons. They gather on both sides of the p-n junction to form a potential difference. When the external circuit is connected, under the action of this voltage, a current will flow through the external circuit to produce a certain output power. The essence of this process is that the process of converting photon energy into electric energy is completed by solar panels.
Solar landscape lamp itself has high ornamental quality. It also emphasizes the coordination and unity of the landscape of art lamp with the history and culture of the scenic spot and the surrounding environment, and uses different shapes, different light colors and brightness to create the landscape.
