Description of drawings

Fig. 1 is the structural representation of the desk lamp of an embodiment.

Fig. 2 is the use sketch map of the desk lamp of an embodiment.

The specific embodiment

To combine specific embodiment and accompanying drawing that the utility model desk lamp is described in further detail below.

As shown in Figure 1, the desk lamp of an embodiment comprises lamp socket 10, light emitting module 20 and is connected lamp socket 10 and the lamp stand 30 of light emitting module 20.Wherein, light emitting module 20 is electrically connected with lamp stand 30 separably.When needing, light emitting module 20 can be separated from desk lamp, uses separately as flashlight.

In the present embodiment, light emitting module 20 profiles are similar with general flashlight, comprise lamp holder 22 and the lamp body 23 that is connected with lamp holder 22.Lamp holder 22 roughly is a bowl type, and front end has light-emitting window, is provided with light source in the light-emitting window.Light source can be existing desk lamp or flashlight bulbs commonly used such as tengsten lamp or LED (light emitting diode, light emitting diode) lamp.Light-emitting window place envelope has light-passing board, in order to the protection light source.

Lamp body 23 is roughly column, and inside is cavity, is used to place rechargeable battery.Lamp body 23 outer walls are provided with the light switch 24 that is used to control circuit on-off between rechargeable battery and the light source.Light switch 24 can be a kind of in knob, button and the toggle switch.Be formed with screw thread on the outer wall of the end of lamp body 23.The end of lamp body 23 is provided with charging inlet.In the present embodiment, charging inlet comprises first conductive metal sheet that is positioned at a circle at lamp body 23 terminal surface centers, and around annular second conductive metal sheet of this first conductive metal sheet.

Lamp stand 30 comprises the connector 32 that links together separably with light emitting module 20, and the shaft 33 that connects connector 32 and lamp socket 10.Connector 32 is the column of an end opening.Limit and be formed with the screw thread corresponding internal thread terminal on the inwall of this opening with lamp body 23.The bottom of opening is formed with the charging head corresponding with above-mentioned charging inlet.In the present embodiment, charging head is two metal columns from the base projections of opening, and wherein first metal column is from the umbo of bottom, and corresponding with first conductive metal sheet, second metal column is near first metal column, and is corresponding with second conductive metal sheet.Preferably, first and second metal columns have certain elasticity.

Shaft 33 preferably can bend by arbitrary shape, and inner having held the electric wire that connects charging head and lamp socket 10.

Lamp socket 10 can be different shapes such as discoid, square, establishes the charging circuit that is electrically connected with said wires in it.Also be provided on the lamp socket 10 controlling the charge switch 12 that this charging circuit is electrically connected with said wires, and the electric wire and the plug that are used to connect charging circuit and external power supply.

In the present embodiment, lamp body 23 links together so that the mode of threaded engagement is separable with lamp stand 30.Among other embodiment, lamp body 23 also can link together so that the mode of buckle is separable with lamp stand 30.For example connector 32 is the column of an end opening; Limit on the inwall of this opening and be formed with buckle structure; And being formed with projection corresponding or crook on the outer wall of the end of lamp body 23 with this buckle structure, buckle structure and projection or crook snap together separably.

Understandable, charging inlet and connector also can adopt existing different shape and connected mode.

During normal the use, the plug of desk lamp is linked to each other with external power source, open charge switch 12 and light switch 24, light source promptly begins luminous, and illumination is provided.Preferably, in the light emitting module 20 smart circuit can be set, this smart circuit is controlled external power source when desk lamp is connected to external power source be that light source provides the circuit of electric power and is the rechargeable battery charging simultaneously.When not using, light switch 24 or charge switch 12 closed get final product.

When needing to use light emitting module 20 separately, light emitting module 20 is taken off from lamp stand 30, open light switch 24 and get final product, very easy to use.
