Abstract

The invention discloses an electronic device. The electronic device comprises a rechargeable battery; a heating device; a heat conduction film, which is arranged on the surface of the heating device and is used for conducting the heat dissipated by the heating device; at least one temperature difference power generation piece, of which the hot end is arranged at the side, away from the heating device, of the heat conduction film, and which is used for converting the heat emitted by the heating device into electric energy; and a charging control circuit, which is electrically connected with the temperature difference power generation piece and the rechargeable battery, and is used for controlling the process of charging the rechargeable battery by utilizing the electric energy generated by the temperature difference power generation piece. According to the electronic device, the heat emitted by the component in the circuit is utilized to charge the battery, so that the problems of reducing the service life of the device and wasting energy due to the generation of a lot of heat in the working process of the electronic device are solved, and service time of the battery is increased under the condition of having no external power supply.

Description

technical field [0001] Embodiments of the present invention relate to the field of electronics, and in particular, to an electronic device. Background technique [0002] With the advancement of science and technology, electronic devices can be seen everywhere in today's human life, and there are various types. A large part of the electronic equipment is composed of light-emitting and heat-emitting devices such as displays and light-emitting devices, printed circuit boards (Printed Circuit Board, PCB) and integrated circuit chips. [0003] Among them, the light emitting diode (Light Emitting Diode, LED) in the light emitting device is widely used, and can be used as an indicator light of various switching devices, a flash light for taking pictures, and a backlight source of a liquid crystal display in an existing display, etc. [0004] In the current LED lighting technology, the luminous efficiency of LED is only 130Lm / W, and the efficiency of converting electrical energy in...
