[0025] The following further describes the solution of the present application in conjunction with the accompanying drawings:

[0026] Embodiment 1

[0027] See the appendix Figure 1-11 , a detachable spotlight, including a housing 100, a light source module 200 and a driving power supply 300.

[0028] The housing 100 is provided with a receiving cavity 101 for receiving the light source module 200 and an opening 102 communicating with the receiving cavity 101; the light source module 200 is embedded in the receiving cavity 101 through the opening 102.

[0029] The light source module 200 is provided with elastic pieces 4, the elastic pieces 4 include two buckling parts 41, and the two buckling parts 41 can elastically converge inward or rebound outward; the inner wall of the receiving cavity 101 is provided with two opposite hanging parts; the elastic pieces 4 are stuck between the two hanging parts and the two buckling parts 41 are respectively hooked on the two hanging parts.

[0030] In the light source module 200 of this technical solution, it can be fixedly connected by hooking the elastic buckling parts 41 on the hanging parts of the housing 100. During installation, the light source module 200 can be pushed in by embedding it into the housing 100; during disassembly, an external pulling force is applied to the light source module 200 to make the two buckling parts 41 elastically converge inward and disengage from the hanging parts, and the operation is simple and fast. When it is necessary to repair or replace the light source, the light source module 200 can be directly disassembled without disassembling the whole lamp, which is convenient for later maintenance.

[0031] The housing 100 includes an outer frame 1; the outer frame 1 includes a top plate 11 and two side plates 12; the two side plates 12 are arranged in parallel, the top plate 11 is located between the two side plates 12 and connects the top sides of the two side plates 12; the interval space between the bottom sides of the two side plates 12 forms the opening 102 of the receiving cavity 101.

[0032] The two side plates 12 are respectively provided with long strip-shaped hanging ribs 121 extending towards both ends; the hanging parts are the hanging ribs 121.

[0033] The light source module 200 includes an inner frame 3, and a plurality of elastic pieces 4 are provided. Each elastic piece 4 is fixed on the inner frame 3 and is spaced apart along the extending direction of the hanging rib 121.

[0034] In this technical solution, the hanging parts are long strip-shaped ribs, which can be used for the buckling parts 41 of multiple elastic pieces 4 to be buckled and hooked. It is not necessary to independently set multiple hanging parts, and the installation positions of each elastic piece 4 can be spaced apart along the extending direction of the hanging rib 121, which is suitable for light source modules 200 of different sizes and reduces the installation and production difficulty.

[0035] The buckle portion 41 includes an elastic arm 411 and a V-shaped protrusion 412; along the direction from the opening 102 of the receiving cavity 101 to the top plate 11, the elastic arms 411 of the two buckle portions 41 of each spring sheet 4 extend outwardly in an inverted "eight" shape; the V-shaped protrusion 412 is located at the extended end of the elastic arm 411, and the tip of the V-shaped protrusion 412 faces outward so as to be hooked on the bearing and hanging portion on the same side.

[0036] If Figure 9 As shown in the figure, along the direction from the opening 102 of the receiving cavity 101 to the top plate 11, that is, from bottom to top in the figure, the side of the hanging rib 121 close to the opening 102 is provided with a first guiding inclined surface 1211 inclined from outside to inside, which guides the buckle part 41 for easy installation.

[0037] During installation, the V-shaped protrusion 412 contacts the first guide slope 1211, and moves inward under its guidance to reduce the width between the two buckle parts 41 and pass over the hanging rib 121, hooking on the other side of the hanging rib 121. At this time, the two elastic arms 411 keep the tendency to pop outward and get stuck between the two hanging ribs 121.

[0038] The two buckle parts 41 of each spring sheet 4 are symmetrically arranged; each spring sheet 4 also includes a plane middle part 42 connecting the two buckle parts 41; the spring sheet 4 is fixedly connected to the inner frame 3 through a spring sheet screw 43; a connecting hole 421 is provided on the plane middle part 42; a long spring sheet connecting groove 34 is provided on the inner frame 3; the spring sheet screw 43 passes through the connecting hole 421 and is screwed to the spring sheet connecting groove 34.

[0039] The spring piece connection groove 34 is long and extends to both ends of the inner frame 3, corresponding to the extension direction of the receiving rib 121. Multiple spring pieces 4 can be fixed on the same spring piece connection groove 34 or multiple connection grooves.
