Detailed Description

The present utility model will be described in further detail with reference to the accompanying drawings. In the description of the present utility model, it should be understood that the azimuth or positional relationship indicated by the azimuth words such as "upper, lower" and "top, bottom", etc. are generally based on the azimuth or positional relationship shown in the drawings, and are merely for convenience of description and simplification of the description, and these azimuth words do not indicate or imply that the apparatus or element to be referred to must have a specific azimuth or be constructed and operated in a specific azimuth, without limiting the scope of protection of the present utility model; the orientation word "inner and outer" refers to inner and outer relative to the contour of the respective component itself.

As shown in fig. 1-5, an led down lamp convenient to replace comprises a power module and a lamp body module; the power supply module comprises a power supply shell 1, a rotary table 2 is arranged on the power supply shell, two grooves are formed in the rotary table, and a first conductive piece 3 is arranged in each groove; the lamp body module comprises a lamp shell 4, a light source piece 5 is arranged in the lamp shell, the light source piece is connected with two second conductive pieces 6 through wires, and the second conductive pieces can be in plug-in fit with the grooves; the power supply shell is provided with an accommodating groove for accommodating the lamp shell, the lower end of the lamp shell is provided with a protruding edge 7 in an outward protruding mode, the lower end of the power supply shell is provided with a step part 8 for accommodating the protruding edge, the protruding edge is connected with the step part through a hanging structure, and a locking structure is further arranged between the protruding edge and the step part; spring clips 9 are mounted on two sides of the power supply shell.

Like this, when the installation, carousel and power supply shell rotate to be connected, and the lamp body upwards inserts in the holding tank of power supply shell, and protruding edge gets into step portion simultaneously, and the second electrically conductive piece gets into the recess and switches on with first electrically conductive piece, rotates the lamp body, makes the lamp body be connected with the power supply shell through the structure of hanging, later locks the lamp body on the power supply shell through locking structure. After the installation is completed, the led lamp tube is installed on the ceiling through the spring clip. Direct current is generated between the lamp body module and the power supply module, and when the power supply module is connected with an external power supply, the lamp body module can obtain power supply to enable the light source component 4 to generate light.

When the light source part needs to be replaced, the lamp housing is detached, the light source part is replaced, the lamp cylinder does not need to be detached, and cost can be reduced better.

Specifically, the turntable is made of insulating rubber, and the lamp housing and the power supply housing are made of insulating materials. When rotating the lamp body, because the second electrically conductive piece is located the recess, the second electrically conductive piece can drive the carousel and rotate, is provided with 4 in the application and articulates the structure, when dismantling, the rotation home of carousel is less than 30 degrees, can not cause the winding of wire.
