Multi-color-temperature full-spectrum LED solar lamp illumination control system

Abstract

The invention provides a multi-color-temperature full-spectrum LED sun lamp illumination control system. The system comprises a solar cell panel, a solar voltage stabilizing circuit, a lithium battery, an environment detection module, a battery management chip, a mains supply circuit, a constant-current circuit, a control protection circuit, a power conversion circuit, a lithium battery power supply switching circuit, a control chip and a multi-color-temperature LED array. According to the invention, the commercial power and solar energy are combined for power supply; moreover, the whole powersupply stability is good, and the circuit structure is simpler compared with the prior art; on the other hand, illumination of a street lamp can be controlled according to changes of light and visibility of the environment, thereby guaranteeing that street lamp illumination can meet the environment change requirement, and road traffic and pedestrian safety is guaranteed.

Description

technical field [0001] The invention relates to an LED lighting control system, in particular to a multi-color temperature full-spectrum LED solar lighting control system. Background technique [0002] Due to the advantages of energy saving and long service life, LED lamps are widely used in street lighting. In the existing street lighting, solar lamps are also a kind of LED lighting lamps. Multi-color temperature and full-spectrum LED arrays are arranged in solar lamps. Through The LED array emits light to simulate sunlight. In the prior art, a single mains power supply or a combined solar-mains power supply is generally used for power supply of solar lamps. However, the existing combined solar power and mains power supply has the following defects: On the one hand, the existing The entire circuit system combined with solar power and power supply is complex, and the stability cannot be guaranteed. On the other hand, the existing solar lamp lighting is manually controlled to...

[0002] Due to the advantages of energy saving and long service life, LED lamps are widely used in street lighting. In the existing street lighting, solar lamps are also a kind of LED lighting lamps. Multi-color temperature full-spectrum LED arrays are arranged in solar lamps. Through The LED array emits light to simulate sunlight. In the prior art, a single mains power supply or a combined solar-mains power supply is generally used for the power supply of solar lamps. However, the existing combined solar power and mains power supply has the following defects: On the one hand, the The entire circuit system combined with solar power and power supply is complex, and the stability cannot be guaranteed. On the other hand, the existing solar lamp lighting is manually controlled to realize the opening and closing of the solar lamp. This method cannot adapt to the environment. On the other hand, due to human factors, the sun lamp is not turned on when the light is insufficient, which poses a safety hazard
