[0007] The utility model provides an LED lamp holder with a sealed structure, which adopts the following technical solutions:

[0008] An LED lamp holder with a sealing structure comprises: a shell, a lampshade mounted on the shell, and a light source module mounted inside the lampshade, the light source module comprising a light source board, an LED light source arranged on the light source board, and a module lampshade covering the outside of the LED light source, a first sealing structure is provided between the shell and the lampshade, the first sealing structure comprises a water retaining rib provided on the shell and a sealing strip provided on the water retaining rib, the water retaining rib is provided on the end surface of the shell facing the lampshade, the water retaining rib is provided in an annular shape, and the outer edge of the end surface of the lampshade facing the shell is provided.

[0009] By adopting the above technical solution, during installation, the sealing ring is first installed in the groove of the module lampshade, and then the module lampshade is placed on the side of the light source board where the LED light source is provided, and the module lampshade is fixed to the light source board using the lampshade fixing bolts. During the process of fixing the light source board with the lampshade fixing bolts, the sealing ring will be pressed between the light source board and the module lampshade to form a second sealing mechanism between the light source board and the module lampshade, and then the light source board and the module lampshade are installed on the shell together, and the lampshade is fixedly installed on the shell, and the light source board and the module lampshade are jointly covered inside the lampshade. When fixing the lampshade and the shell, the sealing strip is first wrapped on the water retaining rib, and then an end face of the lampshade where the annular boss is provided is placed on the shell, and the annular boss cover is placed on the periphery of the water retaining rib. When the annular boss cover is placed on the periphery of the water retaining rib, the sealing strip will be squeezed by the fixing groove set on the inner ring surface of the annular boss and form a first sealing structure between the shell and the lampshade. In this way, a double-layer lampshade is set around the LED light source, and a first sealing structure is set between the lampshade and the shell, and a second sealing structure is set between the module lampshade and the light source board, so that the lamp head has better sealing performance and reduces the probability of damage to the lamp head caused by contact between water and the LED light source.

[0011] By adopting the above technical solution, when the lampshade is installed on the shell, the annular boss on the lampshade can be supported on the limit platform, so that the sealing strip is subjected to appropriate extrusion force, reducing the degree of extrusion on the sealing strip, thereby keeping the sealing strip in appropriate elasticity and extending the service life of the sealing strip; at the same time, the setting of the conical surface on the annular boss can also play a guiding role, thereby realizing rapid alignment of the sealing strip with the fixing groove, providing convenience for the shell and the lampshade; setting the water retaining rib to a structure higher than the limit platform can block water between the water retaining rib and the limit platform, reducing the corrosion of the sealing strip caused by water accumulation on the sealing strip, and further improving the sealing between the shell and the lampshade.
