   DETAILED DESCRIPTION OF THE INVENTION 
   Referring to  FIGS. 1˜5 ,  FIG. 1  is an exploded view of the lamp structure according to the invention;  FIG. 2  is an assembly view of the lamp structure according to the invention;  FIG. 3  is a diagram illustrating the electric connection between elements of the lamp structure according to the invention;  FIG. 4  is a diagram depicting the first position state of the lamp structure according to the invention; and  FIG. 5  is a diagram depicting the second position state of the lamp structure according to the invention. The lamp structure ( 1 ) of the invention comprises a housing ( 10 ), an illumination member ( 20 ), a power supply member ( 30 ), an electrical loop member ( 40 ) (as shown in  FIG. 3 ), a tongue member ( 50 ), an elastic element ( 60 ), and a stationary board ( 70 ). An embodiment of the invention is described in detail below. 
   In the lamp structure ( 1 ) of the invention, the housing ( 10 ) is a casing structure with a hollow member ( 100 ), at one end of the housing ( 10 ) there being provided an opening member ( 11 ) that communicates with the hollow member ( 100 ), and penetrates through the hollow member ( 100 ) to the exterior of the housing ( 10 ). The outer edge of the end of the housing ( 10 ) at where the opening member ( 11 ) is formed has a beveled guide plane ( 12 ), which reduces the volume of the housing ( 10 ) while adding to the convenience of housing ( 10 ) installation. 
   In the lamp structure ( 1 ), the illumination member ( 20 ) includes one or a plurality of illuminating elements ( 22 ), the illuminating elements ( 22 ) being a light-emitting diode (LED) or any light source driven by DC power. The illumination member ( 20 ) can further include a transparent shade body ( 24 ) being engaged to a lateral opening at the other end of the housing ( 10 ) and covering the illuminating elements ( 22 ). 
   The transparent shade body ( 24 ) can have an optical structure such as an optical lens arrays or a marking structure with special design to soften the light rays emitted by the illuminating element ( 22 ) passing through, or redirect the path of light rays to confine the effective irradiating direction of the light rays. 
   In the lamp structure ( 1 ), the power supply member ( 30 ) provides the power source for the lamp structure ( 1 ). More specifically in an embodiment, the power supply member ( 30 ) is assembled in the hollow member ( 100 ) of the housing ( 10 ). The power supply member ( 30 ) contains a battery holder to support a general battery (not shown in the figures) for the power supply. The power supply member ( 30 ) can also be a power source outside the housing ( 10 ). Specifically, the power supply member ( 30 ) is an external battery pack or a transformer, electrically connected to the city power system. The electrical connection that guides the power supplied by the power supply member ( 30 ) to the electrical loop member ( 40 ) such that the power needed by the illumination member ( 20 ) can be supplied sufficiently. Further, a locater is disposed at an outer side of the power supply member ( 30 ) to face the opening member  11  after the power supply member ( 30 ) is placed in the housing ( 10 ) for locating an end of an elastic member ( 60 ), which will be described afterwards. 
   In the lamp structure ( 1 ), the electrical loop member ( 40 ) is an electrical loop electrically connecting the illumination member ( 20 ) to the power supply member ( 30 ), and comprising a first electric terminal ( 42 ) and a second electric terminal ( 44 ). The first electric terminal ( 42 ) and the second electric terminal ( 44 ) are in the state of disconnection and arranged at the inner side of the end with the opening member  11  with the other ends thereof extending the power supply member ( 30 ) respectively. In addition, the first electric terminal ( 42 ) and the second electric terminal ( 44 ) can respectively be a plate body with conductivity that is made of conductive material or a non-conductive baseboard with conductive material arranged thereon. 
   In the lamp structure ( 1 ), the tongue member ( 50 ) is arranged inside the hollow member ( 100 ) of the housing ( 10 ) and confined to move between the first position (as shown in  FIG. 4 ) and the second position (as shown in  FIG. 5 ), and disposed with a conductive piece ( 51 ) thereon. The conductive piece ( 51 ) is a conductor attached to a side of the tongue member ( 50 ) to correspond to the first electric terminal ( 42 ) and the second electric terminal ( 44 ). The tongue member ( 50 ) further comprises an extension member ( 52 ) extending outward from the side attached with the conductive piece ( 51 ) and a guide block ( 53 ) facing the other lateral opening of the hollow member  100  When the tongue member ( 50 ) is at the first position, the extension member ( 52 ) is retracted inside the hollow member ( 100 ) via the opening member ( 11 ); and when the tongue member ( 50 ) is at the second position, the extension member ( 52 ) protrudes outward the housing via the opening member ( 11 ). 
   Moreover, under the action of the recoil force of the elastic element ( 60 ), the extension member ( 52 ) is not subjected to an external force such that the position corresponding to the conductive piece ( 51 ) is in contact with the first electric terminal ( 42 ) and the second electric terminal ( 44 ) to charge the electrical loop member ( 40 ); when the extension member ( 52 ) is under the push of the external force, the conductive piece ( 51 ) disengages the first electric terminal ( 42 ) and the second electric terminal ( 44 ) such that the electrical loop member ( 40 ) is in an electrically disconnected state. 
   The hollow member ( 100 ) of the housing ( 10 ) is further coupled with a first plate body ( 80 ) and a second plate body ( 82 ), wherein the first plate body ( 80 ) is disposed between a first position and a second position where the tongue member ( 50 ) can move therebetween and covers one end of the hollow member ( 100 ). The second plate body ( 82 ) covers other parts on said end of the hollow member ( 100 ). The first plate body ( 80 ) has a guide groove ( 800 ) that can be coupled with the guide block ( 53 ). The coupling of guide block ( 53 ) and the guide groove ( 800 ) is to confine the moving direction of the tongue member ( 50 ) such that it only moves between the first position and the second position. 
   The elastic element ( 60 ) is a mechanical element with recoil force, such as a spring, a spring sheet or a block made of elastic material. One end of the elastic element ( 60 ) is disposed inside the hollow member ( 100 ), while the other end is mechanically connected to one end of the tongue member ( 50 ), wherein one end of the elastic member ( 60 ) is disposed at the external side of the power supply member ( 30 ) in the hollow member ( 100 ). 
   In the lamp structure ( 1 ), the conductive piece ( 51 ) of the tongue member ( 50 ) can select the state between the first electric terminal ( 42 ) and the second electric terminal ( 44 ) to be disconnected or connected; the two electric terminals are in the state of connection when the conductive piece ( 51 ) is electrically connected to them and being in the state of disconnection when the conductive piece ( 51 ) disengages from them; the first position corresponds to the disconnection state as selected by the tongue member ( 50 ), while the second position corresponds to the connection state as selected by the tongue member ( 50 ); and the position at where the extension member ( 52 ) protrudes from the housing ( 10 ) surface corresponds to any position between the first position and second position of the tongue member ( 50 ). 
   Referring further to  FIG. 4  and  FIG. 5  which shows respectively a diagram with the lamp structure of the invention inside a cabinet in first position and second position, the lamp structure ( 1 ) can be used in a cabinet ( 90 ), in which a stationary board ( 70 ) is premounted securely inside the cabinet ( 90 ). After the stationary board ( 70 ) is mounted on the cabinet ( 90 ), the housing ( 10 ) is assembled to the stationary board ( 70 ), wherein the two opposing sides at one end of the stationary board ( 70 ) are each extended with a protruding block ( 72 ), and the corresponding sides of the housing ( 10 ) are each configured with an insertion slot ( 13 ) that matches the protruding block ( 72 ). The insertion slot ( 13 ) has an inwardly extended wing member ( 130 ) on the side, whereas the protruding block ( 72 ) has a flange ( 720 ) on one side that matches the wing member ( 130 ). The wing member ( 130 ) is further disposed with a first trough member ( 132 ), and the protruding block ( 72 ) is disposed with a second trough member ( 722 ) at the side of the flange ( 720 ). The part of protruding block ( 72 ) next to the second trough member ( 722 ) can be inserted directly into the first trough member ( 132 ), and the part next to the first trough member ( 132 ) can also be inserted into the second trough member ( 722 ). Such design aims to reduce the path length during assembly to cut down the time of assembly by user. 
   Again referring to  FIG. 4  and  FIG. 5 , the lamp structure ( 1 ) is installed inside the cabinet ( 90 ) by screwing or latching the stationary board ( 70 ) securely inside the cabinet ( 90 ) (this is not a feature of the invention, hence will not be elaborated). Next as described above, the housing ( 10 ) is assembled on the stationary board ( 70 ) with its opening member ( 11 ) facing the exterior of the cabinet ( 90 ) and the side of housing ( 10 ) with illumination member ( 20 ) facing the interior of the cabinet ( 90 ). When a door ( 92 ) of the cabinet ( 90 ) is closed, the door ( 92 ) would push the extension member ( 52 ) to cause the tongue member ( 50 ) move inwardly inside the housing ( 10 ), which drives the guide block ( 53 ) to move in the guide groove ( 800 ) to reach a predetermined first position. As such, the elastic element ( 60 ) is also squeezed and compressed so that the conductive piece ( 51 ) on the tongue member ( 50 ) would disengage the first electric terminal ( 42 ) and the second electric terminal ( 44 ) and results in electric disconnection. As such, the illumination member ( 20 ) does not produce light rays. Conversely, if the door ( 92 ) of the cabinet ( 90 ) is open such that the door ( 92 ) cannot exert force on the extension member ( 52 ), the elastic member ( 60 ) will release the recoil force to push the tongue member ( 50 ) and protrude the extension member ( 52 ) out of the opening member ( 11 ) which causes the tongue member ( 50 ) to move to the predetermined second position. As such, the conductive piece ( 51 ) is in contract with the first electric terminal ( 42 ) and the second electric terminal ( 44 ). At this time, the circuit is charged and the illumination member ( 20 ) can produce light to illuminate the interior of the cabinet ( 90 ). 
   The side of the housing ( 10 ) opposing the tongue member ( 50 ) has a beveled guide plane ( 12 ) to prevent the mechanical interference between the cabinet door ( 92 ) and the housing ( 10 ) when mounting the housing ( 10 ) inside the cabinet ( 90 ), hence rendering the installation of housing ( 10 ) more convenient. 
   As described above, the invention provides a lamp structure that allows the user to light up the interior of a cabinet. The invention possesses inventive step and meets the essential criteria for new utility patent. 
   The present invention has been disclosed in detail. However the disclosed embodiment should not be construed as a limitation on the actual applicable scope of the invention, and as such, all modifications and alterations without departing from the spirits of the invention and appended claims shall remain within the protected scope and claims of the invention.
