Abstract
The invention relates to a lamp head sealing structure which comprises a lamp shell, a transparent or translucent piece and a lamp cover. The lamp cover is provided with a pressing ring, and the transparent or translucent piece is compacted between the lamp shell and the pressing ring. The lamp head sealing structure further comprises a sealing piece which is coated at the rim of the transparent or translucent piece. The radial section of the sealing piece is U-shaped. The lamp head sealing structure only needs one sealing piece to realize the sealing of the transparent or translucent piece; therefore, the structure is simple and the cost is reduced; moreover, the transparent or translucent piece is separated from the lamp shell by the sealing piece, so that the impact resisting property is good.
