Abstract
The invention discloses an LED lamp body structure with a protective film. The LED lamp body structure comprises a lamp body. A groove is formed in the inner wall of the bottom of the lamp body. A first annular boss which protrudes out of the inner wall of the bottom of the lamp body is arranged at the edge of the groove. A second annular boss which protrudes out of the inner wall of the bottom of the lamp body and is coaxial to the first annular boss is arranged on the periphery of the first annular boss. An LED lamp panel is installed at the position, located between the first annular boss and the second annular boss, of the inner wall of the bottom of the lamp body. The protective film is arranged on the LED lamp panel and seals the LED lamp panel between the first annular boss and the second annular boss. According to the LED lamp body structure with the protective film, the protective film is arranged on the LED lamp panel to seal the LED lamp panel, dust can be prevented from entering LED light emitting particles inside an LED lamp, dark spots are prevented from generating on the LED light emitting particles, and the due service life of the LED lamp is guaranteed.
