Problems solved by technology

Because the power generation capacity of the solar cell will decrease or fail when it is damaged by external force impact or blocked from sunlight, the power storage performance of the battery will continue to decline after multiple charges and discharges, the LED light-emitting module will fail or the light efficiency will decrease, etc. All these factors will lead to the phenomenon that the luminous brightness of solar LED lights is reduced or not lit at night.
Moreover, solar LED lights are often used for public lighting, and most of them are installed in places where there are few people. Therefore, when there is a problem with the solar LED lights and cannot work normally, if it is not because of active inspections, it is often not possible to obtain the failure of the solar LED lights or do not meet the lighting requirements in time. Feedback information required so that maintenance cannot be performed in a timely manner

Abstract

The invention discloses a solar LED lamp circuit with an abnormal state distinguishing function. The solar LED lamp circuit comprises a solar battery, a charging control circuit, a storage battery, a constant-current driving circuit, an LED light-emitting module, a microprocessor circuit, an electric quantity detection circuit, a sunlight detection circuit, a light detection circuit, an alarm circuit and a communication module circuit. The microprocessor circuit judges whether the solar LED lamp circuit works abnormally according to detection signals of the electric quantity detection circuit, the sunlight detection circuit and the light detection circuit, and sends an abnormal state corresponding to the solar LED lamp circuit to the communication module circuit when the solar LED lamp circuit works abnormally. The advantages of the present invention are that when the solar LED lamp circuit is abnormal and cannot work normally, the abnormal state of the solar LED lamp circuit can be judged, and the abnormal state information is sent to a terminal management device in a radio mode, so that management personnel can know the abnormal condition in time, and maintenance can be effectively carried out in time.

Description

technical field [0001] The invention relates to a solar LED lamp circuit, in particular to a solar LED lamp circuit with an abnormal state discrimination function. Background technique [0002] Solar LED lights are especially suitable for installation in relatively remote places because there is no need to arrange mains power supply lines. During the day, solar LED lights convert sunlight into electrical energy and store it, and at night solar LED lights convert the electrical energy stored during the day into light for lighting. [0003] Such as figure 1 As shown, the existing solar LED light circuit usually includes a solar cell, a sunlight detection circuit, a charging control circuit, a storage battery, a constant current drive circuit, an LED light-emitting module, a power detection circuit and a microprocessor circuit. The power detection circuit is connected to the battery, charging The control circuit is respectively connected to the solar battery and the storage b...
