What are the characteristics of solar lighting?

As we all know, oil, natural gas and coal are non-renewable resources, and their extensive use will not only cause energy depletion, but also cause great damage to the environment. However, our production and life are inseparable from light energy and heat energy. In order to ensure energy security and protect our living environment, people have studied and used solar energy. Applying solar energy to lighting not only saves resources, but also is very efficient, achieving the goal of sustainable development.

Solar lighting _ concept

Solar lighting actually uses equipment to convert the light energy of the sun into electric energy, and then provides running energy for lighting tools. The energy of solar lighting is the light energy of the sun. During the day, the energy of the mobile phone is stored in the battery. When needed, the stored energy can be released through the controller, which can provide light for people.

Solar lighting is a kind of environmental protection lighting, which consumes energy and does not emit harmful substances, so it will not cause damage to the ecological environment. In addition, solar energy is a renewable resource, unlike oil and coal, which will be gone when used up.

Solar energy is easy to collect and will not be exhausted. This energy-saving and environment-friendly lighting method has covered the whole lighting field.

Solar lighting _ characteristics

Energy saving and environmental protection: solar energy does not need electricity or other energy sources to provide energy, but only needs the energy of the sun to provide lighting.

Solar lighting will not release any harmful substances in use, which is harmless to the environment.

Economical and efficient: because solar lighting does not need to use electric energy, there is no problem of electricity bill. Although solar lighting is more expensive than ordinary lamps, it has no follow-up cost and is more cost-effective. Moreover, the brightness of solar lighting is very good, and now many urban roads are equipped with solar lighting, and the effect is very good.

Convenient installation: As mentioned above, solar lighting does not need electricity, and there is no electricity fee, so naturally there is no need to install wires. So its installation is very simple, just fix the lamp and battery, which is very convenient.

Solar lighting _ classification

According to the power supply mode, it can be divided into three types: independent solar photovoltaic lighting, wind-solar complementary lighting and commercial complementary solar lighting. Independent use of solar photovoltaic lighting depends only on solar energy to provide lighting energy, and requires the use of enlarged batteries; In addition to solar energy, solar lighting with complementary scenery can also obtain energy through wind turbines, and this electromagnetic capacity can be designed to be smaller; The complementary lighting of solar energy and commercial power is suitable for areas with insufficient solar illumination time and wind power.

In this way, when the reserve energy is not enough in rainy days, the city power can be supplemented.

Function: This classification is to distinguish solar lighting used in different occasions, including solar signal lamp, solar lawn, solar landscape lamp, solar marker lamp, solar street lamp, solar insecticidal lamp, solar light box and solar flashlight.

According to power supply mode: There are two power supply modes for solar lighting, one is direct power supply and the other is indirect power supply. Direct power supply is directly provided by the battery; Indirect power supply uses an inverter to convert direct current into alternating current and then provide it to the light source. The power loss of indirect power supply will increase.

Conclusion: Solar energy is a new type of energy discovered by people, which will not damage the environment and is renewable. When solar energy is used in the field of lighting, many solar lighting products appear. Everyone fully understands the classification of solar lighting and how widely it is used in our lives.
