Description
Technical field
The utility model relates to a kind of desk lamp, particularly relates to a kind of Foldable desk lamp.
Background technology
Desk lamp is the one of lamp, and this electrical equipment is mainly placed on desk or dining table, for the use of illumination.The bright range of exposures of desk lamp is relatively little and concentrated, thus can not have influence on the light in whole room, and effect is confined to around desk lamp, is convenient to read, learn, and saves the energy.
Chinese patent application publication No. is CN104132272A, Shen Qing Publication day is that the application for a patent for invention on November 05th, 2014 discloses a kind of Folding desk lamp, comprise lampshade, support and base, described lampshade, support and base are long plate shape structure, a groove is had at lampshade lower surface, the both ends of groove are all fixed with interface, the head end of support and the tail end of lampshade hinged, the tail end of support and the head end of base hinged.The Folding desk lamp of this kind of structure, although structure is simple, volume after folding is little, be convenient to transport or carry, need first desk lamp is extinguished, then just start to fold, due to carelessness, desk lamp may be folded like this, but forget and turn off desk lamp, thus cause waste electric energy.
Utility model content
Technical problem to be solved in the utility model is to provide that a kind of light-emitting component can the Foldable desk lamp of power-off after Folding desk lamp.
For solving the problems of the technologies described above, the utility model provides a kind of Foldable desk lamp, comprise base, support arm and lamp body, one end of described support arm is connected with described base rotation by the first rotating shaft, the other end of described support arm is rotationally connected by the second rotating shaft and described lamp body, described first rotating shaft is provided with the first conducting strip, in described base, is provided with the second conducting strip, described first conducting strip can be made during described first axis of rotation with described second conducting strip contact or be separated.
Described second conducting strip is arc-shaped conductive film.
Described support arm comprises epimere support arm and hypomere support arm, and described epimere support arm portion is telescopic to be arranged in described hypomere support arm.
Described in when described support arm and the angle of described base are less than 10 degree, the first conducting strip is separated with described second conducting strip.
Described first conducting strip is Elastic Contact when contacting with described second conducting strip.
Described first conducting strip is contacted with described second conducting strip by the projection being arranged on its end.
Compared with prior art, the beneficial effects of the utility model are: because the utility model includes the first conducting strip and the second conducting strip, this first conducting strip is separated after desk lamp is folding automatically with the second conducting strip, circuit is disconnected, thus extinguishes after making lamp body power-off.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is circuit theory diagrams of the present utility model.
In figure: base 2, support arm 4, lamp body 6, the first rotating shaft 8, second rotating shaft 10, first conducting strip 12, second conducting strip 14, protruding 16.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with embodiment and accompanying drawing, the utility model is described in further details.At this, exemplary embodiment of the present utility model and illustrating for explaining the utility model, but not as to restriction of the present utility model.
Shown in Figure 1, a kind of Foldable desk lamp, comprise base 2, support arm 4 and lamp body 6, wherein an end of support arm 4 is rotationally connected with base 2 by the first rotating shaft 8, another end of support arm 4 is rotationally connected with lamp body 6 by the second rotating shaft 10, whole like this desk lamp just can be folded, special feature of the present utility model is: the first rotating shaft 8 is provided with the first conducting strip 12, the second conducting strip 14 of arc is provided with in base 2, the first conducting strip 12 can be made to contact with the second conducting strip 14 or be separated when the first rotating shaft 8 is rotated, in actual use: the first conducting strip 12 is by an Electrode connection of light-emitting component in wire and lamp body 6, another electrode of light-emitting component is connected with power supply by wire, second conducting strip 14 is directly connected with power supply by wire, circuit loop shown in pie graph 2, when desk lamp launches gradually, first conducting strip 12 rotates with the rotation of the first rotating shaft 8, contact with the second conducting strip 14 afterwards, make the circuit loop conducting shown in Fig. 2, light-emitting component electrified light emitting, when desk lamp is folding gradually, first conducting strip 12 rotates with the rotation of the first rotating shaft 8, be separated with the second conducting strip 14 afterwards, preferably when support arm 4 and the angle of base 2 are less than 10 degree, the first conducting strip 12 is separated with the second conducting strip 14, circuit loop shown in Fig. 2 is disconnected, light-emitting component power-off is extinguished.
Preferably the second conducting strip 14 is arc-shaped conductive film, be wearing and tearing after preventing the first conducting strip 12 and the second conducting strip 14 Long-Time Service and cause loose contact simultaneously, first conducting strip 12 and the second conducting strip 14 are for can produce elastically-deformable copper sheet, and the first conducting strip 12 is by being arranged on projection 16 and second conducting strip 14 Elastic Contact of its end.
Preferred support arm 4 comprises epimere support arm 40 and hypomere support arm 42, and epimere support arm 40 part is telescopic to be arranged in hypomere support arm 42, can make the height adjustable of desk lamp like this, thus be user-friendly to.
