Problems solved by technology

Although solar energy is the source of all energy in the world, due to the influence of climate and seasons, the solar energy irradiated on the earth's surface is very scattered and unstable, so it is not easy to use solar energy directly
And based on the current technology and cost, the power of solar power generation is generally relatively small, and it is only used for small power loads

Abstract

The invention discloses a solar corridor sensing LED lighting device, which comprises an LED lighting device, a solar power generation device, a battery and a detection control unit. The battery forms a power supply circuit and a first charging circuit respectively with the LED lighting device and the solar power generation device. The solar corridor sensing LED lighting device also comprises a first switching device which is connected with the anode end and the cathode end of the solar cell power generation device in a crossing way and a second switching device which is connected with the LED lighting device in series. The invention has the advantages of convenient and intelligent use, energy conservation, environmental protection and the like. Moreover, since the whole circuit has the function of multi-level protection, the device can be used more safely and stably, and has a longer service life.

Description

technical field [0001] The invention relates to a solar corridor induction LED lighting device Background technique [0002] According to statistics, lighting consumption accounts for about 20% of the total power consumption, and reducing lighting power consumption is an important way to save energy. Although solar energy is the source of all energy in the world, due to the influence of climate and seasons, the solar energy irradiated on the earth's surface is very scattered and unstable, so it is not easy to directly use solar energy. And based on the current technology and cost, the power of solar power generation is generally relatively small, and it is only used for small power loads. This requires us to consider the following elements when using solar energy as a lighting power source: 1. The input power of the light source should be small; 2. The luminous efficiency of the light source should be high; 3. The energy conversion efficiency of the system should be high. ...
