Referring to fig. 4, in an embodiment, the sidewall 130 includes a base 131 perpendicular to the bottom wall and an extending portion 132 bending outward, and the first rib is disposed on the base 131. The extension 132 is used to connect with the lampshade 200.

Wherein, the lamp cover 200 and the mounting seat 100 are integrally injection molded. The engagement portion is located between the extension 132 and the lamp housing 200. The structural strength is higher, the appearance is simpler, and the assembly steps are also reduced.

In one embodiment, the outer wall of the mounting base 100 is provided with a slot 160 for installing the connector 500, and the led lamp is fixed on a support (e.g., a wall or a wood board, etc.) through the connector 500. The bottom wall 140 is perpendicular to the base 131 of the sidewall 130, the two sides of the bottom wall 140 in the width direction of the tube body are provided with third ribs 141 protruding from the outer surface, and the third ribs 141 and the base 131 of the sidewall 130 form a locking groove 160. The third ribs 141 are flush with the bottom wall 140, and the appearance is more concise.

The structure of the connector 500 may be variously configured according to different installation situations, and the connector 500 can slide along the slot 160 to accommodate different installation distances. The installation convenience of the LED lamp is improved.

The power supply connection mode of the LED lamp and the corresponding assembly details are described below.
