Claim:
A waterproof LED lamp holding structure, comprising: an object showing a geometrical shape and having an outer side and an inner side with a plurality of through holes formed thereon to show geometrical patterns or characters; and at least an LED lamp bank formed from a plurality of LED lamps serially connected via an electric wire, each of the LED lamps having a light-emitting section and a contact pin section, and having a rear part enclosed in a protective member to shield a junction of the contact pin section and the electric wire against external environment; each of the LED lamps being inserted into one of the through holes from the inner side toward the outer side of the object, and being held in the through hole via the protective member with the light-emitting section forward projecting from the outer side of the object; the waterproof LED lamp holding structure being characterized in that the protective member has a first end closer to the light-emitting end of the LED lamp and a second end opposite to the first end, the light-emitting section of the LED lamp is forward projected from the first end of the protective member, and the electric wire is rearward extended out of the second end of the protective member; and that the protective member is provided on an outer face near the first end with a plurality of wedge-like keys, each of which is extended from near the first end toward the second end with the thickness of the wedge-like key gradually increasing toward the second end; and that the protective member is provided on the outer face near the second end with a plurality of anchoring lugs, which are outwardly obliquely extended from near the second end toward the first end; whereby when the LED lamp along with the protective member are inserted into the through hole on the object, the wedge-like keys pass through the through hole to abut on the outer side of the object and distal ends of the anchoring lugs abut against the inner side of the object, holding the LED lamp immovable and straight in the through hole on the object.
