Charge and discharge circuit based on lifting work lights

Abstract

The invention provides a charge-discharge circuit based on a lifting work light for discharging the work light and an external electronic apparatus. The charge-discharge circuit comprises: a power storage module for receiving the power supplied by a power generating module; a voltage drop detection module for detecting the voltage of the power storage module; a voltage divider module for dividing the voltage of the power storage module to the voltage drop detection module; a relay module for controlling the power supply of the power storage module to the external apparatus, a voltage conversion module for converting the voltage of the power storage module into a standard USB charging voltage; and a USB interface module for providing connection ports for USB data lines. The backward stage of the power storage module is joined to the voltage conversion module and the USB interface module so that the voltage of the power storage module is capable of being output to the external electronic apparatus by the USB, in order to take full advantage of the electricity generated by the power generating module. Furthermore, the power storage module is capable of storing the electricity, therefore can supply power to a lamp if the power generating module stops power generation, in order to prolong the working time of the lifting work light.

Description

technical field [0001] The invention relates to a lifting work light, in particular to a charging and discharging circuit based on a lifting work light for external discharge. Background technique [0002] The lifting work light is mainly composed of three parts: the lamp head, the lifting rod and the skeleton assembly. There are generally two lamp heads, which are fixed on the top of the lifting rod with fixing nuts, and the direction can be adjusted arbitrarily within the range of 180°. The LED light source and lens are installed in the lamp head, so that the light is projected. After the lifting rod is fully raised, it can reach a height of more than 2 meters, and after shrinking, the height is about 0.7 meters. The user can adjust the height arbitrarily between 0.7-2 meters according to needs. The skeleton component is mainly used to fix the skeleton of the lamp power supply part and carry the mobile device. Among them, the power supply components include digital freq...
