Background technique

Solar energy is a kind of clean energy, which is developed and utilized by more and more countries. China is a country rich in solar energy resources. The sunshine time is long, and more and more solar energy products are developed and utilized. Solar street lamp technology is one of them. As the technology of solar street lights becomes more and more mature, solar street lights are widely promoted and used. During the day, the solar cell components charge the battery pack, and at night the battery pack supplies power to the DC light load. Safe operation; through the controller, the solar street light can work independently, without laying cables, and is easy to install. However, the existing solar street lights only capture the intensity of light through the light sensor, and control the on and off through the controller. Due to the dusty roads, the sensitivity of the light sensor is not high due to long-term use, and the existing solar street lights cannot be adjusted according to the season. Different adjustments to the time of turning on and off the street lights, resulting in a certain amount of waste of electricity.

Contents of the invention

In order to overcome the deficiencies of the prior art, the purpose of this utility model is to provide a solar street lamp, which adopts a reverse connection protection circuit and dual control of the on-off time of the street lamp, so as to realize the purpose of adjusting the on-off time of the street lamp according to seasonal changes.

In order to achieve the above purpose, the utility model includes a light pole, a support pole, a solar panel assembly, a battery pack, a lamp, a controller, a light sensor, a power detection device, an overcharge protection circuit, and an overdischarge protection circuit. The support pole, the front end of the support pole is equipped with a lamp, the solar panel assembly is installed on the top of the light pole, the controller and the battery pack are installed under the solar panel assembly and inside the light pole, and the controller is respectively connected to the light sensor, power detection device, overcharge The protection circuit and the over-discharge protection circuit, the over-charge protection circuit is arranged between the solar panel assembly and the battery pack, and the over-discharge protection circuit is installed on the battery pack and the lamp branch; it is characterized in that the controller is also connected with a clock circuit, and the solar energy A reverse polarity protection circuit is also installed on the battery board assembly and the branch circuit of the battery pack.

The working mode of the controller is divided into two modes: winter and summer. The month is monitored through the clock circuit, and when the month reaches the threshold value set inside the controller, the controller switches the on-off time of the control lamp.

The overcharge protection circuit and the overdischarge protection circuit are composed of relays.

The reverse connection protection circuit is composed of a one-way switch.

Compared with the prior art, the utility model is under the control of the controller, the solar panel assembly charges the battery pack during the day, and the battery pack supplies power to the DC lamp load at night, and the overcharge and overdischarge protection circuit protects the battery pack from being damaged. If it is damaged due to overcharge or overdischarge, the light intensity is captured by the light sensor, and the time is timed by the clock circuit. When the preset time is reached, the light sensor does not send a signal to the controller, and the lamp is forced to light up. At the same time, it is divided into There are two seasons in summer and winter, and each season corresponds to a lighting time, which is more conducive to energy saving, environmental protection and road safety.
