This model relates to a power-off structure for a mosquito trap. The main structure includes at least one carrier, at least one first carrier, at least one second carrier, at least one first elastic element, at least one second elastic element, At least one pressing part, at least one power supply device, and at least one switch part. The first carrying part is used to carry a first light emitting element, and the second carrying part is used to carry a second light emitting element. With the above structure, when the user removes the first light-emitting element from the first carrying part, the carrying body will bounce up due to the first elastic element to keep the pressing part away from the switch part, thereby turning off the power supply device , And the second light-emitting element is also turned off. Thereby, by removing one side of the lamp tube, the other side of the lamp tube immediately cut off the power of the linkage structure, which can improve the overall safety of use.本新型為有關於一種捕蚊燈之斷電結構，主要結構包括至少一承載體、至少一第一承載部、至少一第二承載部、至少一第一彈性元件、至少一第二彈性元件、至少一壓擠部、至少一供電裝置、及至少一開關部，第一承載部係供承載一第一發光元件，而第二承載部係供承載一第二發光元件。藉上述結構，當使用者將第一發光元件由第一承載部上取下時，承載體即會因第一彈性元件而彈起，以使壓擠部遠離開關部，進而使供電裝置斷電，並且連帶使第二發光元件斷電。藉此，透過移除單側燈管，另一側燈管隨即斷電之連動結構，即可提升整體使用上之安全性。
