The present invention discloses an LED lamp tube structure that utilizes gravity self-convection to accelerate heat dissipation, which relates to the technical field of heat dissipation lamp tube structures. It includes a lamp holder, a lamp cover, and an LED lamp body installed inside the lamp holder. It further includes: a heat dissipation component and an adjustment component arranged inside the lamp holder. When heat dissipation inside the lamp holder is required, based on the principle that hot air with a low density rises under the upward net buoyancy force and cold air with a high density sinks downward, natural air from the outside flows in through the air inlet, enters the low-position port through the ventilation openings on the sliding block, and then flows into the inside of the lamp holder through the openings on the connecting plate. After the natural air enters, it quickly fills the space at the bottom of the lamp holder. The original hot air inside the lamp holder rises and flows out through the heat dissipation openings, and the natural air fills the vacancy, prompting the heat to quickly move upward and be discharged. Moreover, the natural air is heated by the heat of the LED lamp body and becomes hot air, and the continuous input of natural air realizes the self-convection cycle heat dissipation inside the lamp holder.
