Preferably, described warning LED light source is red LED light source.

Preferably, also comprise handle, described handle is arranged on described lamp housing.

The beneficial effect of the utility model LED portable lamp is:

For illuminating LED light source provides constant electric current, drive illuminating LED light source luminescent, for user provides highlight illumination by LED drive circuit; Drive the flicker of warning LED light source by LED flashing circuit, serve as warning, flash caution function can should use in the time of car light fault or other fault; By change-over switch, highlight illumination pattern and flash caution pattern are switched, simple to operate, practical.

Accompanying drawing explanation

Fig. 1 is the structural representation of LED portable lamp in an embodiment of the utility model LED portable lamp;

Fig. 2 is the circuit block diagram of LED portable lamp in an embodiment of the utility model LED portable lamp.

Realization, functional characteristics and the advantage of the utility model object, in connection with embodiment, are described further with reference to accompanying drawing.

The specific embodiment

Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.

See figures.1.and.2, propose an embodiment of the utility model LED portable lamp, this LED portable lamp comprises lamp bracket 10 and illuminating lamp body, and illuminating lamp body is hinged on lamp bracket 10.This LED portable lamp also comprises handle 50, and handle 50 is arranged on lamp housing 20, is convenient to the handling of light fixture.Illuminating lamp body comprises lamp housing 20, is arranged on LED light source structure 30, LED drive control module and charging, supply module in lamp housing 20, and charging, supply module are the power supply of LED drive control module.This charging, supply module comprise charging circuit 61 and the rechargeable battery 62 being connected with charging circuit 61, on illuminating lamp body, be provided with the charging inlet 60 being electrically connected with the input of charging circuit 61, be connected with external power source by charging inlet 60, charge for rechargeable battery 62 by charging circuit 61, the electric energy storing after rechargeable battery 62 chargings is the power supply of LED drive control module.
