Solar highway tunnel light emitting diode (LED) illumination system with brightness adjustment and synchronous electricity generation and utilization

Abstract

The invention discloses a solar highway tunnel light emitting diode (LED) illumination system with brightness adjustment and synchronous electricity generation and utilization, wherein a photovoltaic battery component, a storage battery and an LED constant current driving and brightness adjusting circuit are respectively connected and controlled through a controller; a power supply selection circuit chooses a storage battery power supply or a filter output power supply to supply power for the LED constant current driving and brightness adjusting circuit; and illumination intensity inside or outside a tunnel is consistent by automatically adjusting LED illumination brightness inside the highway tunnel so that damage on human eyes or even accidents are avoided, and simultaneously system load and the energy production of a solar battery are kept synchronous by automatically adjusting the illumination brightness, therefore a solar electricity generating system is more high-efficient, safer and more energy-efficient.

Description

technical field [0001] The invention relates to the field of highway tunnel lighting by using solar energy, in particular to a lighting system that can automatically adjust the lighting brightness of LED lamps in the tunnel according to external light, keep the brightness consistent inside and outside the tunnel, and realize the synchronization of the power load of the lighting system and the power generation of solar cells. Solar road tunnel LED lighting system. Background technique [0002] In recent years, the construction of national highways has been rapidly extended. Due to the complex terrain and numerous mountains in our country, the use of highway tunnels is also increasing. According to the requirements of my country's road tunnel ventilation and lighting design specifications, road tunnels over 400m need to install lighting facilities. However, most road tunnels are built in sparsely populated mountainous areas, where the cost of wiring is high, and line failures...
