What is solar lighting?
Solar lighting is based on solar energy, which can realize photoelectric conversion through solar panels. In the daytime, battery is used to store and store electric energy, and in the evening, controller is used to supply power to electric light source, so as to realize the required functional lighting.
What are the components of solar lighting system？
Solar lighting system consists of solar panels, charge and discharge controllers, batteries, lighting lamps, cables and other main parts.
Types of solar lighting system:
1.According to the classification of solar photovoltaic lighting power supply
- Independent solar lighting system
Independent use of solar photovoltaic lighting is solar panels, batteries, lighting components, controllers and mechanical structures and other components together, with solar energy as energy, outdoor off grid, independent use of lighting devices containing one or more lighting components. It needs to be equipped with larger solar panels (3 ~ 5 times of the light source power) and batteries to store energy.
- Solar and wind lighting system
In order to improve the efficiency and reduce the design capacity of solar panels, wind turbines and solar panels are added to the independent solar lighting devices.
- Solar and electricity complementary lighting system
Solar energy and electricity complement each other. Solar energy is the main energy source for lighting in the evening. When the battery energy storage is insufficient in rainy days, the lighting device powered by electricity can reduce the installed capacity of solar panels and batteries.
2.According to the use of occasions and function classification
- Solar signal lamp
Compared with ordinary signal lamp, solar signal lamp is more environmentally friendly and energy-saving. Due to its power storage function, it does not need to lay cables during installation, which can effectively avoid power failure caused by construction. In continuous rain, snow and cloudy days, the solar signal lamp can work normally for 72 hours.
Navigation, aviation and land traffic lights play an important role, many local power grids can not supply power, and solar signal lights can solve the problem of power supply, the light source is mainly small particle oriented LED light source. Good economic and social benefits have been achieved.
- Solar lawn lamp
Solar lawn lamp is a kind of green energy lamps, with the characteristics of safety, energy saving, environmental protection, easy installation and so on. Under the illumination of light, the battery energy is stored in the battery through the solar panel, and in the absence of light, the battery energy is sent to the load led through the controller. It is suitable for residential community green grass beautification, lighting embellishment and park lawn embellishment.
The power of light source is 0.1 ~ 1W, and small particle light emitting diode (LED) is generally used as the main light source. The power of solar panels is usually 0.5 ~ 3W.
- Solar landscape lamp
It is used in square, park, green space and other places. It uses various shapes of low-power LED point light source, line light source, and cold cathode shape lamp to beautify the environment. Solar landscape lamp can get better landscape lighting effect without destroying green space. It has the advantages of high brightness, simple installation, stable and reliable operation, no cable laying, no consumption of conventional energy, long service life, etc., and it is a green energy product vigorously advocated in today’s society.
- Solar indicator lamp
It is used for the lighting of guidance indication, door number and intersection sign at night. The requirement of luminous flux of light source is not high, the configuration of the system is low, and the usage is large. Generally, the light source of identification lamp can be low-power LED or cold cathode lamp.
- Solar street lamp
It is one of the main applications of solar photovoltaic lighting device, which is used in rural roads and rural roads. The light sources used are small power high pressure gas discharge (HID) lamp, fluorescent lamp, low pressure sodium lamp and high power LED. Due to the limitation of its overall power, there are few cases applied to urban trunk roads. With the complementary of municipal lines, solar photovoltaic lighting street lamps will be used more and more on the main road.
- Solar insecticidal lamp
It can be used in orchards, plantations, parks, lawns and other places. Generally, the fluorescent lamp with specific spectrum is used, and the more advanced LED purple lamp is used to trap and kill pests through its specific spectral line radiation. It is widely used in agriculture, vineyards, citrus orchards, bayberry orchards, litchi orchards, apple orchards, mango orchards, vegetable bases, tea gardens, organic rice, sugarcane, tobacco, peanuts, cotton, flowers, forest farms, urban greening, parks and other fields that need to be exterminated. It is a kind of high-tech and pollution-free physical pest control equipment, which provides reliable scientific and technological guarantee for the production of pollution-free and high-quality agricultural products, obtaining organic certification and Developing Sightseeing ecological agriculture in the vast crop planting bases.
- Solar light box
Solar advertising light box with a unique design concept for the advertising industry to open up a new field. It not only has the original propaganda function of advertisement, but also lights up the landscape environment of city and community. Without wires and cables, it adds a different landscape to our life. It adopts solar power generation system, light source adopts imported metal halide lamp, SCM charge discharge control, high frequency energy-saving electronic ballast with DC output, and 12V maintenance free battery. There are output overload protection, output short circuit protection, input reverse connection protection, overcharge and overdischarge automatic power-off protection lamp function.
The solar advertising light box also has the functions of high luminous efficiency, uniform light distribution, light control or time control automatic switch. It is suitable for the main streets, parking lots, hotels, tourist areas and other public places with more night crowd activities.
- Solar flashlight
The solar energy is stored in the internal storage battery, and the LED light-emitting tube is used, which has good concentration and good lighting effect. It can be used in outdoor activities or emergencies.
- Solar Household light
Compared with ordinary LED lamps, solar lamps have built-in lithium batteries or lead-acid batteries, and one or more solar panels are connected to charge them. Generally with charging or remote control function, the shape varies according to the needs of users.
- Solar garden light
Solar cell module made of monocrystalline silicon or polycrystalline silicon, bracket, lamp post, lamp cap, special bulb, storage battery, battery box, ground cage, etc. The shape of lamp cap is colorful, colorful, unique and elegant. The solar garden lamp can make the city road, commercial and residential district, park, scenic spot, square, courtyard, playground and so on picturesque. The product can work 8 to 10 hours a day for about 4-5 days of continuous lighting with sufficient electricity.
3.Classification according to power supply mode of solar photovoltaic lighting source
- Direct power supply
The electricity generated by the solar panel is stored in the battery, which directly supplies power for the light source.
- Indirect power supply (inverter power supply) inverter converts DC into AC, and then supplies power for lighting source. Inverter power supply will increase power loss by 10% ~ 20%.
