Abstract
The utility model provides an emergency lamp bulb. The emergency lamp bulb comprises a housing, wherein the front end of the housing is provided with a light-transmittable shade; an LED (light emitting diode) light source is formed in the light-transmittable shade; the rear end of the housing is provided with a threaded plug; a storage battery and a control circuit board are arranged in the housing; an alternating-direct current transforming module and a control switch which is exposed outside the housing are arranged on the control circuit board; the control circuit board is electrically connected with the threaded plug, the LED light source and the storage battery, respectively; a hanging component is further formed on the housing; the alternating-direct current transforming module is used for transforming external alternating current into low-voltage direct current, so as to supply power to the LED light source or charge the storage battery. The emergency lamp bulb has the following beneficial effects: as the storage battery is embedded in the bulb, the bulb can be used emergently in power failure; furthermore, the lamp bulb is provided with the hanging component, so that the bulb can be released and separated from a lamp holder and hung in other situations for use.
Description
Technical field
The utility model relates to a kind of bulb.
Background technology
Bulb generally all comprises a built-in light source and for being connected to the screw thread plug on lamp socket.In use, settle on outer lamp socket and use.But in power-off, bulb just can not be bright.
Summary of the invention
In order to overcome the existing bulb deficiency that lamp can not be lighted in power-off, the utility model provides a kind of emergent bulb that bulb also can be lighted in power-off.
The technical scheme in the invention for solving the technical problem is: a kind of emergent bulb, comprise a housing, described housing front end is a diffuser, it in described diffuser, is a LED light source, the rear end of described housing is a screw thread plug, in described housing, be provided with a battery and a control circuit board, described control circuit board is provided with to be handed over straight power transformation module and exposes the gauge tap outside housing, and described control circuit board is connected with screw thread plug, LED light source, storage battery respectively; On described housing, be also provided with a hanging piece.Described gauge tap is controlled the switch of lamp and selected the power supply source of LED light source is battery or external power supply.The straight power transformation module of described friendship is in order to external alternation electricity is changed into low-voltage DC, in order to power or to charge a battery to LED light source.
A selection for hanging piece, described hanging piece is a hook, described hook is hinged on described housing.
Further, on described housing, the first from left right side is provided with two hinge holes, and described hook lower end is divided into two, in described two described hinge holes of the right insertion of a first from left.
The utility model is inserted in screw thread plug on lamp socket in use, and external alternation electricity charges a battery and LED light source power supply through handing over straight power transformation module to change low-voltage DC at ordinary times; In the time of power-off, stir gauge tap and select battery to power and can light to LED light source; And hanging piece is set on housing, bulb Panasonic can be departed to lamp socket and hang over other occasions uses.
The beneficial effects of the utility model are: internal battery in bulb, can be when having a power failure Emergency use, and with hanging piece, bulb Panasonic can be departed to lamp socket and hang over other occasions and use.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
By reference to the accompanying drawings 1 to 4, a kind of emergent bulb, comprise a housing 1, described housing 1 front end is a diffuser 2, in described diffuser 2, be a LED light source 3, the rear end of described housing is a screw thread plug 4, and in described housing, 1 is provided with a battery 5 and a control circuit board 6, described control circuit board 6 is provided with to be handed over straight power transformation module 7 and exposes the gauge tap 8 outside housing, and described control circuit board 6 is electrically connected to screw thread plug 4, LED light source 3, battery 5 respectively; On described housing 1, be also provided with a hanging piece 9.Described gauge tap 8 is controlled the switch of lamp and selected the power supply source of LED light source 3 is battery 5 or external power supply.The straight power transformation module 7 of described friendship is in order to external alternation electricity is changed into low-voltage DC, in order to give LED light source 3 power supplies or accumulators 5 chargings.
, described gauge tap 8 has 3 gears, is respectively DC shelves, OFF shelves, and AC shelves, when described gauge tap is during in DC shelves, described gauge tap disconnects hands over being electrically connected to of straight power transformation module 7 and screw thread plug 4, and battery 5 is directly powered to LED light source 3; When gauge tap is in OFF shelves, gauge tap disconnects LED light source 3, battery 5 and hands over being electrically connected to of straight power transformation module 7, and lamp goes out; When described gauge tap is during in AC shelves, the straight power transformation module 7 of described friendship changes low-voltage DC into LED light source 3 power supplies external alternation electricity, accumulators 5 chargings simultaneously.
A selection for hanging piece, described hanging piece 9 is a hook, described hook is hinged on described housing 1.Further, on described housing 1, the first from left right side is provided with two hinge holes 10, and described hook lower end is divided into two 11, in the described hinge hole 10 of the right insertion of described two 11 1 the first from left.
The utility model is inserted in screw thread plug in use on lamp socket and connects external alternation electricity, and gauge tap is positioned at AC shelves at ordinary times; In the time of power-off, stir gauge tap and select DC shelves.
The beneficial effects of the utility model are: internal battery in bulb, can be when having a power failure Emergency use, and with hanging piece, bulb Panasonic can be departed to lamp socket and hang over other occasions and use.
