Patent ID: 7731382

Claim:
A lamp structure comprising: a case including a housing structure with a hollow part, having a top opening and a lower opening sealed with an upper lid and a lower lid respectively, and having an end opening part for the hollow part communicating with the outside of the case; a light emitting part including a plurality of light emitting elements installed on the surface of the case; a power supply being the main power source of the entire structure, and being disposed inside the case next to the lower lid; an electrical circuit mainly for electrically connecting the light emitting part to the power supply further comprising a first electrical contact and a second electrical contact, and the first electrical contact and the second electrical contact forming an open circuit to each other; a sliding piece having two opposite sides, being installed inside the case next to the upper lid, being restricted to move between a first position and a second position, and further comprising a conductor and an extension, wherein the conductor is disposed at one of the opposite sides of the sliding piece corresponding to the first electrical contact and the second electrical contact, the extension further comprises an extension rod and a circular plate shaped press detent, one end of the extension rod connects with the conductor, the other end of the extension rod keeps contact with a side surface of the press detent, and the press detent is capable of moving to pass through the opening part; two protruding strips being disposed next to the first and second electrical contacts respectively, and sandwiching the sliding piece; a spring element being disposed at another one of the two opposite sides of the sliding piece, having one end affixing to a stopper joined to the case, and having the other end secured to the sliding piece; wherein the conductor is electrically connected to the first contact and the second electrical contact to form a close circuit state when the press detent is free from being pushed and protrudes out of the case via the opening part to result in the sliding piece being moved to the first position, and disengages from the first electrical contact and the second electrical contact to form an open circuit state when the press detent is pushed against an elastic recovery force of the spring element and moves into the case via the opening part to result in the sliding piece being moved to the second position.
