The present invention relates to a structure of an insect trap lamp, comprising: a first housing having an adjusting portion and an abutting portion； and a second housing having a engaging portion and a joint portion, wherein the adjusting portion includes a positioning portion and a blocking portion a portion, a placing portion, and a blocking portion, and the engaging portion is disposed through the adjusting portion and fixed to the adjusting portion, and the engaging portion is slidably pivotally connected to the mating portion, and the first housing defines an abutting portion, And a lure lamp set at a side of the butt joint, and a placement portion is defined at a side of the lure lamp group, and a trapping component is disposed on the placement portion； and the first shell and the second shell are disposed when the engaging portion is located at the positioning portion The bodies are tightly closed to each other for normal use. When maintenance is required, the first housing can be lifted and lifted by one hand, the joint portion and the butt portion are slid and pivoted, and the engaging portion is placed across the blocking portion. The placement part is half-opened to facilitate the maintenance of the insect-catching components, thereby making the present invention practical and easy to disassemble and maintain.本新型為有關於一種捕蟲燈之結構，其包括有具調節部和對接部之第一殼體、及具卡合部和接合部之第二殼體，而調節部包含有定位部、阻隔部、擺放部、及擋止部，且卡合部受調節部穿設並置放固定於調節部上，而接合部與對接部滑移樞接，而第一殼體上界定有對接部、及位於對接部側處之引誘燈組，且引誘燈組側處界定有置放部，並置放部上設有捕蟲元件；當卡合部位於定位部時，第一殼體與第二殼體相互靠緊呈封閉狀態以供正常使用，需維護時可單手抬起搬動第一殼體，使接合部與對接部滑移樞轉，且將卡合部跨過阻隔部擺放於擺放部呈半開狀態，以利於替換捕蟲元件等維護，藉此令本新型達到便於拆裝維護之實用進步性。
