Solar Warning Light

Solar warning lights which is a kind of traffic light converting the solar energy to electricity are mainly used to alert people at night or in low light conditions. It will convert the solar energy to to electricity by absorbing them and save them in battery. Solar warning lamps can light by itself without any external power, easy to install and environment protection.

Working principle of Solar warning lights

The working principle of solar warning lights is based on the photovoltaic effect. During the day, solar panels receive solar radiation and convert it into electrical energy, which is stored in batteries. When night falls and there is insufficient light, the electrical energy in the batteries is automatically released to light up the warning lights. This design enables solar warning lights to work automatically without human supervision, reducing maintenance costs.

Application of Solar warning lights

Solar warning lights are applied to various occasions with warning, including but not limited to the followings:

Traffic intersections: bridges, warning booths, turning intersections, construction sites, etc.

Facility surroundings: high-voltage lines, tower cranes, road facilities, ships, planting areas, tower cranes, navigation channels, etc.

Among traffic lights, solar warning lights can reduce the occurrence of traffic accidents; in high-voltage line warning lights, they provide guidance for aircraft flying at night to ensure flight safety.

Advantages of Solar warning lights

‌Environmental protection and energy saving‌: Using solar energy as energy reduces dependence on traditional power grids, reduces energy consumption and environmental pollution.

Easy installation and maintenance‌: No wiring is required, the installation is simple, the maintenance cost is low, and it has the characteristics of waterproof, high temperature resistance, lightning resistance, etc., and can adapt to various harsh environments‌.

Long-lasting battery: Generally, lithium iron phosphate battery or nickel-metal hydride rechargeable battery is used, which is long-lasting, high-energy and environmentally friendly. Some batteries are maintenance-free for more than five years.

Multiple flashing modes: Through integrated circuit management design, a variety of pre-programmed flashing modes are provided, such as red, yellow and blue alternating flashing, strobe, fast flash, slow flash, and flashing.

High-brightness light source: Red LED is often used as the light source, with high brightness, strong signal and long visible distance. For example, the visible distance of TFN7484 solar warning light is more than 500 meters, while the visible distance of solar double-sided 12-light flashing light can reach more than 1000 meters at night.

Sturdy and durable: The outer shell is generally made of polycarbonate or other high-quality materials, which is durable, waterproof, dust proof, impact-resistant, anti-aging and corrosion-resistant.

To sum up, solar warning lights not only have significant advantages in environmental protection and energy saving, but also perform well in practical applications due to their long life and low maintenance costs. With the advancement of technology and the improvement of environmental awareness, the application prospects of solar warning lights will be broader.
