Description

A kind of portable lamp with alarm function

Technical field

The utility model relates to a kind of portable lamp, particularly a kind of portable lamp with alarm function, and it is standby especially to be fit to vehicle.

Background technology

Portable lamp in the market generally all includes lamp housing, is arranged on circuit board, a plurality of led light sources that are connected with circuit board and switch, power supply in the lamp housing.Wherein, the front of lamp housing often has loophole, and under the situation of power connection, led light source gets electric and light that send comes out from the front illuminated of lamp housing, forms the field of illumination.Specifically can also be with reference to Chinese patent: ZL200620101929.4, ZL200720067802.X, ZL200710044640.2.And these portable lamps do not possess alarm function to external world simultaneously, when reality is used, and the zone at the front illuminated user place of portable lamp, and the side of portable lamp, the back side all do not have light to break forth, and make other people be unable to find out the people nearby.This is when the operation of vehicle field maintenance, and especially dangerous, vehicle breaks down when doing emergency maintenance forwardly, can't see showy warning mark if sail the vehicle that comes from the rear, leads to tragedy with regard to being very easy to because of dodging not as good as colliding, thrust into incident.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of portable lamp with alarm function at above-mentioned prior art present situation, it has the caution zone and can play warning function to front vehicle at the back side of lamp housing, be particularly useful for the operation of vehicle field maintenance.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this has the portable lamp of alarm function, comprise lamp housing, be arranged on first circuit board in the lamp housing, the power supply that is arranged on a plurality of main led light source on first circuit board and is electrically connected with first circuit board, wherein, described lamp housing front has loophole and supplies the light of main led light source to pass through, it is characterized in that: also be provided with an alarm module on the back side of described lamp housing, this alarm module comprises the lampshade that covers on the lamp housing back side, second circuit board in the lampshade and be arranged at least one time led light source on second circuit board, this second circuit board and first circuit board are electrically connected.

In portable lamp of the present utility model, have two light emitting modules, one is the light that main led light source sends, it penetrates and uses as the working region illumination from the front of portable lamp, another is the light that time led light source sends, it penetrates and conduct caution area illumination usefulness from the back side of portable lamp, and first, second circuit board is wherein powered by same power supply and worked.

Described second circuit board can be arranged in the lamp housing, and offer loophole at corresponding led light source place of lamp housing and pass through for the light of time led light source, but for making lamp housing be easier to processing, described second circuit board can be fixed on the back side of described lamp housing, and the back side of lamp housing has the lead that aperture is electrically connected with first circuit board for second circuit board and passes through to get final product.

Can stand reposefully on the ground for making portable lamp, need not the user controls, as further improvement, can also include a base that is arranged on lamp housing below, the bottom of this base and lamp housing is rotationally connected to good locating, thereby lamp housing can be rotated relative to ground together with a plurality of led light sources, adjusts light angle, the mode that the location is rotationally connected can adopt existing various technology, no longer repeats here.

For controlling the work of primary and secondary led light source better, can also be provided with first switch, second switch on described second circuit board, these two switches expose to outside the described lampshade, and, first switch is controlled the first circuit board work, and second switch is then controlled the second circuit board work.So, two switches are controlled portable lamp module and warning lamp module respectively.

For making light fixture have waterproof effect, to be applicable to open-air the use, described first, second switch is outer can also to be arranged with a holder, and the holder surface coverage has a button membrane, and the surface of described button membrane exposes to outside the described lampshade by the through hole on the lampshade, for user's operation.

Compared with prior art, advantage of the present utility model is: by set up an alarm module at the lamp housing back side, when making portable lamp can throw light on the working region in dead ahead, can also form the caution zone at the back side of lamp housing, play warning function to external world, during as automobile inspection, can play warning function to front vehicle, and, portable lamp structure arrangement science of the present utility model, reasonable, compact conformation, suitable vehicle carries, be highly suitable for the operation of vehicle field maintenance, be easy to apply.
