The present invention relates to a structure of an insect trap lamp. The main structure comprises an insect trap device including a lamp holder body, a cover body and an insect catching member, and at least one elastic support member disposed on the lamp holder body and the cover body. At least one light-emitting element disposed in the insect-trapping device, at least one power-supply component disposed on one side of the insect-trapping device and electrically connected to the light-emitting component, and at least one disposed in the insect trapping device and electrically connected to the power supply Component power-off device. With the above structure, when the cover body is disposed on the lamp holder body, the power supply component supplies power to the light-emitting component to perform the insect-catching action, and when the user opens the cover body, the power-off device disconnects the power supply component to ensure safety. When the cover body is opened to a predetermined angle, it is automatically supported and fixed by the elastic support member, so that the user can operate with one hand, and the convenience is better.本新型為有關一種捕蟲燈之結構，主要結構包括一包含有燈座本體、蓋體及捕蟲件之捕蟲裝置、至少一設於該燈座本體及該蓋體上之彈性支撐件、至少一設於該捕蟲裝置內之發光元件、至少一設於該捕蟲裝置一側且電性連結該發光元件之供電元件、及至少一設於該捕蟲裝置內且電性連結該供電元件之斷電裝置。藉上述結構，當蓋體罩設於燈座本體時，供電元件乃正常供電給發光元件進行捕蟲動作，而當使用者開啟蓋體時，斷電裝置即斷開供電元件，以確保安全，且於蓋體開啟至預定角度時，透過彈性支撐件自動予以支撐固定，以利使用者單手操作，便利性較佳。
