Embodiment approach

[0041] The LED photovoltaic integrated intelligent street lamp lighting system of the present invention has an overall functional structure as follows figure 1 shown. The street lighting system is jointly powered by photovoltaic panels and mains power. Under normal weather conditions (no continuous rainy weather), the electric energy generated by the photovoltaic panels during the day is stored in the battery by the power harvesting device to supply power for the LED street lighting system. When the battery power is insufficient due to insufficient light for a long time, the system will automatically switch to the mains power supply. After the LED photovoltaic integrated intelligent street light system receives the lighting signal from the central control room at night, all street lights are in the waiting state. When the target to be illuminated (people and moving vehicles, etc.) is detected to pass by, multiple street lights on the same section can perform automatic network...

Abstract

The invention discloses a light-emitting diode (LED) photovoltaic integrating intelligent street lamp system which comprises a mains supply unit, a photovoltaic input unit, an electric energy collection charging unit, a storage battery, an LED lighting unit and a micro controller unit (MCU) data acquisition and processing unit. The photovoltaic input unit is connected with the electric energy collection charging unit, the electric energy collection charging unit is respectively connected with the storage battery and the MCU data acquisition and processing unit, a power supply channel selection unit is arranged between the mains supply unit and the LED lighting unit and further respectively connected with the storage battery and the MCU data acquisition and processing unit, the mains supply unit is connected with the MCU data acquisition and processing unit through an electric energy measuring unit, and the LED lighting unit is connected with the MCU data acquisition and processing unit through a power supply load voltage monitoring unit. The LED photovoltaic integrating intelligent street lamp system guarantees power supply continuity and effectively improves the lighting utilization rate.

Description

technical field [0001] The invention relates to an LED photovoltaic integrated intelligent street lamp system, which belongs to the technical field of LED lighting. Background technique [0002] The development of solar street lights is a hot topic in today's lighting industry, and the main principle of existing solar street lights on the market is that during the day, photovoltaic panels convert solar energy into electrical energy through the photoelectric effect and store it in batteries; at night, use batteries to supply power and set automatic cut-off time . If this method encounters cloudy and rainy days, the energy storage of the battery will be insufficient, and the power supply will not be able to continue at night. [0003] At present, two modes of half-power or interval lighting are widely used in energy-saving control of street lamps. Its working principle is that in the road section or time period with small pedestrian or vehicle traffic, through manual control...
