DETAILED DESCRIPTION

[0019] The present application scheme is further described below in conjunction with the accompanying drawings.

[0020] like Figures 1 to 9 The light source module of a LED downlight shown in the figure comprises a light emitting element 10, a lampshade 20 and a light distribution element 30. The light emitting element 10 comprises a circuit board 101 and an LED lamp bead 102 arranged on the circuit board 101.

[0021] The lampshade 20 includes a peripheral wall 201, an end wall 202 and a reflective cup 203;

[0022] The peripheral wall 201 has a first end 204 and a second end 205 opposite to each other;

[0023] The first end 204 of the peripheral wall is open to form a port 206. The circuit board 101 of the light-emitting element is installed on the first end 204 of the peripheral wall and covers the port 206. The LED lamp beads 102 on the circuit board 101 are located inside the peripheral wall 201.

[0024] The reflective cup 203 is trumpet-shaped and includes a small-diameter end 207 and a large-diameter end 208. Both the small-diameter end 207 and the large-diameter end 208 are open. The small-diameter end 207 is placed into the peripheral wall 201 through the second end 205 of the peripheral wall and reaches the circuit board 101. The LED lamp beads 102 on the circuit board 101 enter the reflective cup 203 through the small-diameter end 207.

[0025] The end wall 202 is connected between the second end 205 of the peripheral wall and the outer side surface of the reflective cup 203 to cover the gap between the second end 205 of the peripheral wall and the outer side surface of the reflective cup 203;

[0026] The peripheral wall 201, the end wall 202 and the reflective cup 203 are integrally formed, for example, by injection molding;

[0027] The light distribution member 30 is detachably mounted on the large-diameter end 208 of the reflective cup.

[0028] The lampshade including the reflective cup designed by this technical solution is formed in one piece, which is assembly-free and can improve production efficiency. In addition, the one-piece structure can achieve better sealing, dustproof, insect-proof and light leakage-proof effects, while the circuit board cover port can achieve the sealing, dustproof, insect-proof and light leakage-proof effects. The light distribution parts can be disassembled and assembled to facilitate the replacement of different light distribution parts according to different usage requirements, thereby improving the flexibility and adaptability of use.

[0029] The large-diameter end 208 of the reflective cup is provided with a circular step surface 209 extending along the edge of the large-diameter end;

[0030] The light distribution member 30 is seated on the step surface 209 and supported by the step surface 209 .

[0031] The technical solution provides a step surface to facilitate installation and support of the light distribution component.

[0032] The large-diameter end 208 of the reflective cup is provided with a buckle structure for buckling the light distribution component 30, thereby realizing that the light distribution component is installed on the large-diameter end of the reflective cup in a detachable manner. This technical solution adopts a buckle structure to facilitate the disassembly and assembly of the light distribution component.

[0033] The buckle structure includes a plurality of inverted hooks 210 that are spaced apart and distributed along the circumference of the step surface 209. This technical solution can facilitate the light distribution component to be stably and reliably mounted on the large-diameter end of the reflective cup.

[0034] All the hooks 210 are located outside the step surface 209. This technical solution can facilitate the disassembly and assembly of the light distribution component.

[0035] The light distribution component 30 is a lens or a light-transmitting panel.

[0036] In this embodiment, Figures 1 to 9 The light distribution element 30 shown is a light-transmitting panel.

[0037] and Fig.10 and Fig.11 The light distribution component 30 shown is a lens, wherein the edge of the lens is provided with a flange 301 for the hook 210 to engage.
