Abstract: A lamp structure includes top case, a bottom case coupled to the top case, a lamp shade coupled to the bottom case, and an LED base board provided between the lamp shade and bottom case. The top case includes a hollow member formed on a top surface, a projecting member inside the hollow member such that a first tank is defined between the hollow member and the first projecting member, a first elastic ring inside the first projecting member, and a first latch member inserted in the first projecting member and configured to press the first elastic ring. The bottom case includes a second projecting member configured to cooperate with an interior surface of the bottom case to define a second tank, a second elastic ring inside the second projecting member, and a second latch member inserted in the second projecting member and configured to press the second elastic ring.

Abstract: The present invention provides a lamp structure, which uses the waterproof structure of the lamp to prevent external liquids from entering the lamp along the wire and hence avoiding risks in industrial safety caused by electrical leakage or sparks. The present invention uses the fixing member of the lamp to meet the installation requirements for different environments. In addition, by using the lens structure of the lamp, the lenses still can be fixed to the lamp after thermal expansion or shakes. Thereby, the risk of lens falloff can be reduced.
