Abstract

The invention belongs to the field of lamps, in particular to a lighting circuit and a portable lamp. In the lighting circuit and the portable lamp, the portable lamp can be switched between two light sources by operating a single-pole triple-throw switch S1 so as to meet the requirements for lighting under different environments. The portable lamp can further work in a charging mode, and therefore the charging requirements under emergency situations are met.

Description

technical field [0001] The invention belongs to the field of lamps, in particular to a lighting circuit and a portable lamp. Background technique [0002] As a kind of portable lighting, portable lamps are widely used in people's daily life, adventure, work and other occasions, providing many conveniences for people's life. [0003] However, most of the existing portable lamps have only one light source, so in different occasions, different light sources cannot be selected in a targeted manner, resulting in unsatisfactory lighting effects. Contents of the invention [0004] The object of the present invention is to provide a lighting circuit, aiming at solving the problem that most of the existing portable lamps only have one light source, which causes unsatisfactory lighting effects. [0005] The present invention is realized in this way, a kind of lighting circuit, described lighting circuit comprises: [0006] Fuse F1, varistor RV, resistor R1, capacitor C1, rectifier...
