A 300W LED solar street light is a high - power, self - sufficient outdoor lighting solution, ideal for gardens, roads, and parking lots due to its strong brightness and energy independence.
Core Components
A complete 300W LED solar street light system consists of four key parts that work together to ensure stable operation.
Solar Panel: Usually with a power of 100W - 200W, it converts sunlight into electrical energy. Common materials are monocrystalline silicon, which has a high conversion rate (about 18% - 23%) and is suitable for areas with sufficient sunlight.
LED Light Source: The 300W LED module provides strong illumination, with a brightness of about 30,000 - 45,000 lumens. It has the characteristics of low energy consumption and long service life (up to 50,000 hours), which is much longer than traditional street lights.
Battery: Stores electrical energy for night use. Lithium - ion batteries are commonly used, with large capacity (usually 100Ah - 200Ah) and good durability. They can work normally in a temperature range of -20℃ to 60℃.
Controller: The "brain" of the system, which controls the charging and discharging of the battery. It has functions such as overcharge protection, over - discharge protection, and light control (automatically turning on the light at dusk and turning it off at dawn).
Key Performance Advantages
This type of street light has obvious advantages compared with traditional grid - connected street lights, making it widely used.
Energy - saving and Environmental Protection: It relies on solar energy for power supply, does not consume grid electricity, and has no carbon emissions. It can save a lot of electricity costs in the long run.
Easy Installation: No need to lay power cables, which greatly reduces the difficulty and cost of construction. It can be installed independently on poles or walls.
Strong Adaptability: It can work normally in harsh outdoor environments. It has waterproof performance (usually IP65 or above) to prevent rainwater damage, and can resist strong winds (up to level 12) and heavy snow.
Intelligent Control: Most products are equipped with intelligent controllers, which can adjust the brightness according to the ambient light or set the lighting time (such as dimming to 50% brightness in the middle of the night) to save power.
Typical Application Scenarios
Its high power and strong illumination make it suitable for multiple outdoor scenarios that require high - brightness lighting.
Road Lighting: Used for rural roads, suburban roads, or community roads, providing sufficient illumination to ensure the safety of pedestrians and vehicles.
Parking Lot Lighting: Illuminates large parking lots in shopping malls, communities, or factories, making it convenient for vehicles to park and pick up at night.
Garden and Square Lighting: Used in large outdoor gardens, scenic spots, or squares, not only providing lighting but also enhancing the safety and aesthetics of the area.
Industrial and Mining Area Lighting: Suitable for outdoor operation areas of factories, mines, or warehouses, meeting the lighting needs of night work.
