Patent ID: 7575337

Claim:
A lamp structure comprising: a housing being a casing structure with a first end, a second end, two opposite sides, a first lateral opening and a second lateral opening, and further comprising a hollow member between said first end and second end, an opening member at said first end to communicate with the hollow member, and an insertion slot being disposed at said two opposite sides respectively with a plurality of wing members and first trough members alternately provided an outer edge of the insertion slot; a stationary board oppositely extending outward a protruding block with a plurality of flanges and second trough members alternately provided at an outer edge of the respective protruding block corresponding to the first trough members and the wing members such that the stationary board is capable of joining with the insertion slots; an illumination member further comprising at least an illumination element being arranged inside the second end of the housing; a power supply member being arranged in the hollow member of the housing and having a locater disposed at an outer side thereof to face said opening member for receiving a battery; an electrical loop member being electrically connected to the illumination member and further comprising a first electric terminal and a second electric terminal, which are disposed at an inner side of said first end and extending to the power supply member and generally in an electrically disconnected state; a tongue member, which is a mechanical element with a first side and a second side, being slidably disposed inside the housing next to said first end and capable of moving between a first position and a second position, and further comprising an extension member, which extends from said first side, penetrates through the opening member and generally protrudes outward the housing, and a conductive piece, which is an electric conductor and disposed at said first side corresponding to the first electric terminal and the second electric terminal; and an elastic element, which is a mechanical element disposed between the tongue member and the power supply member with one end being supported with said locator of the power supply member and the other end being connected to said second side of the tongue member; wherein when the the tongue member is positioned at the first position and the extrusion member is in a state without being pressed, the conductive piece electrically connects with the first electric terminal and the second electric terminal; and when the tongue member is positioned at the second position and the extrusion member is in a state of being pressed against a recoil force of said elastic element, the conductive piece electrically disengages from the two electric terminals.
