The lamp housing includes a light-transmitting silicone lampshade and an opaque silicone lampshade bonded to the light-transmitting silicone lampshade. The LED light strip is installed in the lamp housing. When in use, the lamp beads on the LED light strip emit light outward through the light-transmitting silicone lampshade. However, the following problems exist during use:

[0004] 1. There is only one lamp strip installation area on the lamp housing. If the lamp housing needs to be bent during use at the side or bottom of the lamp housing, different lamp housings need to be used for different bending directions;

[0005] 2. The surfaces facing each other of the translucent silicone lampshade and the opaque silicone lampshade of the lamp housing are coated with glue for bonding. However, during the bending process of the lamp housing, it is subjected to tensile stress and compressive stress, which may cause cracks on the bonding surface, resulting in light leakage and affecting use.

[0010] In this way, the FPC flexible circuit board is an existing structure. During installation, according to the required bending direction, the FPC flexible circuit board can be inserted into the side or bottom of the support frame, which can meet different bending directions and realize the bottom light emission or side light emission requirements through a lamp shell structure, so as to better meet the actual installation requirements. The setting of the support frame can improve the strength of the light-transmitting silicone shell. The placement area is surrounded by the support frame, the placement frame and the diagonal brace, which is convenient for placing and limiting the FPC flexible circuit board.

[0011] Among them, a plurality of outer protrusions are protruding outward on both sides of the placement frame and are arranged at intervals, and a plurality of inner protrusions are protruding inward on both sides of the opaque silicone shell and are arranged at intervals. The outer protrusions and the inner protrusions are alternately arranged and plugged into each other, the outer protrusions are bonded to the inner protrusions and the opaque silicone shell, and the inner protrusions are bonded to the placement frame and the outer protrusions.

[0012] Wherein, the cross-sections of the outer convex block and the inner convex block are both in an "inverted T" shape.
