Solar Lawn Light Principles And Advantages Introduced
Sep 08, 2017

Solar energy has become the power of environmental protection nowadays hero, electric water heaters and gas water heaters are gradually replaced by solar water heaters, the traditional street lights are gradually replaced by solar lawn. Here and everyone to understand what is the solar lawn lamp, as well as the advantages and composition of solar lawn lamp.

1. Solar lawn light - system components

The solar lawn lamp is an independent solar power generation system. It can independently complete the conversion of solar energy into electricity, and can convert electricity into heat for lighting and decoration use, without the need for wire transmission. The main components of the system are photovoltaic power generation systems and power supply systems.

Photovoltaic system

An independent photovoltaic power generation system is generally composed of three parts: solar battery components; charge and discharge controllers, inverters, test instruments and computer monitoring and other power electronic equipment 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 discharge of waste water; no combustion process, no fuel; simple maintenance, low maintenance costs; operational reliability, good stability; Parts of the solar cell life, crystalline silicon solar cell life can reach more than 25 years; according to the need to easily expand the scale of power generation.

3. Power supply system

Solar Lawn Light is a small solar power supply system. Its structure is very simple mainly by the solar panels, charge and discharge controller, battery, lighting circuit and light pole and other components.

4. Solar lawn lamp - structure composition

By the solar cell components (photovoltaic panels), ultra-bright LED lights (light source), maintenance-free rechargeable batteries, automatic control circuits, lamps and other components.

5. Solar lawn light - light source advantages

At present, most of the lawn light selection of LED as a light source, LED long life, can reach more than 100,000 hours, low working voltage, very suitable for use in solar lawn light. In particular, LED technology has been a key breakthrough, and its characteristics in the past 5 years have greatly improved, the performance and price ratio has also been greatly improved. In addition, the LED from the low-voltage DC power supply, the light source control costs low, so that the regulation of light and shade, frequent switches are possible, and will not have an adverse impact on LED performance.

Solar lawn light source and power system design method Because of the unique advantages of solar lawn lamp, in recent years has been rapid development. Lawn lamp power is small, mainly for the purpose of decoration, high mobility requirements, the circuit laying difficult, high water requirements of the site.
