Abstract

The invention discloses a work light with an external charging function. The work light comprises a battery and a control circuit, and further comprises a boost circuit which is connected with the battery and the control circuit, wherein the control circuit is used for controlling whether the boost circuit performs boosting action; and the boost circuit is used for boosting a received voltage of the battery and outputting a charging voltage for charging external equipment. The work light with an external charging function does not only have a lighting function, but also has a function of charging digital products including mobile phones, cameras and the like; and the work light can be used as a mobile power supply for timely supplementing electric quantity to the digital products, so that the digital products can work normally, the work efficiency of staffs is improved, and the great convenience is brought for the staffs.

Description

technical field [0001] The invention relates to a work lamp, in particular to a work lamp with external charging function. Background technique [0002] Work lights are widely used in railway, electric power, public security, steel and other fields, and can be widely used in outdoor scenes such as night work, maintenance and repair, emergency rescue and disaster relief, etc., with low energy consumption, high luminous efficiency, long service life, etc. advantage. [0003] However, the existing work lamps generally only have the function of lighting and do not have the function of external charging. When the staff carry the work lights to carry out outdoor activities and the power of digital products such as mobile phones and cameras is exhausted, it is inconvenient to charge the digital products used by the staff because there is generally no power supply outdoors. The failure of digital products to replenish power in time will directly affect the work efficiency of the s...
