Abstract

The invention relates to the technical field of control, in particular to a flash lamp control circuit and a mobile terminal. The flash lamp control circuit comprises a flash lamp and a current amplification structure; The current amplification structure comprises a first transistor and a second transistor. The current output terminal of the first transistor is connected with the current input terminal of the second transistor. Current amplified by the current amplification structure flows into the flash lamp. The invention solves the problem of serious heat generation of the transistor and reduces the heat generation in the flash lamp control circuit.

Description

technical field [0001] The invention relates to the field of control technology, in particular to a flashlight control circuit and a mobile terminal. Background technique [0002] With the continuous development of science and technology and the continuous improvement of people's living standards, electronic user terminal devices such as mobile phones, tablet computers, notebook computers, and cameras are becoming more and more popular in people's lives. At the same time, with the advancement of digital image processing technology and charge-coupled device (CCD), digital photography technology has reached an unprecedented level. Under such a background, the existing user terminal equipment has a camera function as a basic equipment. On the user terminal with a camera function, in addition to being provided with a lens necessary for taking pictures, a flashlight with a supplementary light function also needs to be provided. [0003] At present, there are mainly two types of...
