Solar energy has become the hero of energy saving and environmental protection nowadays. Electric water heaters and gas water heaters are gradually being replaced by solar water heaters, and traditional street lights are gradually being replaced by solar lawn lights.
System Composition of Solar Lawn Lights
The solar lawn light is an independent solar system. It can independently convert solar energy into electrical energy, and can convert electrical energy into thermal energy for lighting and decoration without wire transmission. The main components of the system are photovoltaic power generation system and power supply system.
An independent photovoltaic system usually consists of three parts: solar cell components; power electronic equipment such as charge and discharge controllers, inverters, test instruments and computer monitors, and batteries or other energy storage and auxiliary power generation equipment.
The photovoltaic power generation system has the following characteristics: no rotating parts, no noise; no air pollution, no waste water discharge; no combustion process, no fuel; simple maintenance, low maintenance cost; operational reliability and stability; as a key component of the solar cell service life Long, crystalline silicon solar cells can be used for more than 25 years, and it is easy to expand the scale of power generation as needed.
Power Supply System
The solar lawn lamp is a small solar power supply system. Its structure is very simple, mainly composed of solar panels, charge and discharge controllers, batteries, lighting circuits and light poles.
The Structure of the Solar Lawn Lamp
It is composed of solar cell components (photovoltaic panels), high-brightness LED lights (light source), maintenance-free rechargeable batteries, automatic control circuits, lamps, etc.
The Light Source Advantages of Solar Lawn Lights
At present, most solar lawn lights use LEDs as light sources. The LED has a long service life, which can reach more than 100.000 hours, and the working voltage is low, which is very suitable for solar lawn lights. In particular, LED technology has made major breakthroughs. In the past five years, its characteristics have been greatly improved, and its cost performance is relatively high. In addition, the LED is powered by low-voltage direct current, and its light source control cost is low, so that the brightness and frequency can be adjusted without adversely affecting the performance of the LED.
Due to the unique advantages of solar lawn lights, the design methods of solar lawn light sources and power systems have developed rapidly in recent years. Lawn lights have low power and are mainly used for decoration. It is suitable for places with high mobility requirements, difficult circuit laying and high waterproof requirements.
