Abstract:
1. An illumination alert apparatus structure having a cap for use in switch control, the illumination alert apparatus comprising: a body; a power unit; and a lightbulb having an illumination unit coupled thereto; wherein the power unit is coupled to an end of the body, and the lightbulb is screwed to an external thread formed on an outward side of the body and coupled to the power unit, so as to assemble the illumination alert apparatus structure having a cap for controllably driving the illumination unit to be on or off; wherein the power unit coupled to an end of the body comprises a battery holder for holding a plurality of batteries and a battery lid engageable with an end of the battery holder, wherein a preset orientation hole is penetratingly formed in the battery lid to allow positive and negative pole conductive rods to extend into the preset orientation hole, wherein springs abut against other ends of the positive and negative pole conductive rods, respectively, such that active ends of the springs abutting against the positive and negative pole conductive rods rest upon conductive elements of the battery holder, respectively, wherein the battery lid is fixed to the battery holder by at least one support element, wherein a stop portion protrudes from an outer rim of the battery lid, such that the stop portion abuts against an O-ring coupled to an inside of a middle annular cover at the bottom of the lightbulb to prevent the power unit coupled to one end of the body from rotating.
