The lamp holder 10 includes an insulating portion 11 and an electrical connector 12. The electrical connector 12 is located below the insulating portion 11 and is fixedly connected to the insulating portion 11. The electrical connector 12 is used for electrically connecting with an external power source to provide power required for the operation of the lamp. [0008] The heat sink 13 is located at the lamp holder 10. The upper portion of the insulating portion 11 and the insulating portion 11 are fixed 100101777. Form No. A0101 Page 3 / Total 12 pages 1002003165-0 201231864 The heat sink 13 includes a body 14 and a plurality of heat radiating fins 15. The body 14 has a hollow cylindrical shape as a whole, and the body 14 includes a first surface 141, a second surface 142 and an outer peripheral surface 143 which are oppositely disposed. The first surface 141 is away from the lamp holder 10 - the side second surface 142 is adjacent to the lamp holder 10 - side, and the outer peripheral surface 143 of the body 14 is connected between the first surface 141 and the second surface 142. The plurality of heat dissipation fins 15 are disposed around the body 14. In the present embodiment, the heat dissipation fins 15 are protruded radially outward from the outer circumferential surface 143 of the body 14. The top end of the heat sink 13 is provided with a plurality of latching portions 151 spaced apart from each other, and a latching groove 156 is formed in each of the latching portions 151. In the present embodiment, the latching portion 151 is protruded from the top end of the heat dissipating fins 15 . The latching portion 1 51 includes a resilient arm 152 and a stop arm 153 . The elastic arm 152 is protruded from the top end of the heat dissipating fin 15 . The stop arm 1 53 is formed by a radially inward projection of the free end of the resilient arm 152. The stop arm 153 includes a guiding surface 154 and a stop surface 155. The guide surface 154 is located inside the stopper arm 153, and the guide surface 15' is bent radially inward and downward by the top end of the stopper arm 153. The stop surface 155 is located at the bottom end of the stop arm 153. The stop surface 15 is directed toward the first surface 141 of the body 14. The stop surface 155 is spaced apart from the second surface i41 of the body 14 to form a card slot 156, ie. ··· -C :i: / ~ .yv. The stop arm 153 is spaced apart from the first surface 14i of the body 14 to form a card slot 156'. The card slot 156 of the latching portion 151 of the plurality of heat sink fins 15 is circumferential. The directions are horizontally connected to form an annular mounting groove 157. [0010] The lamp cover 17 is made of a transparent material such as glass, plastic, or the like. The lamp cover 17 is located above the heat sink 13 and is connected to the heat sink 13 to form a receiving space 175. In the present embodiment, the lamp cover 17 and the first surface 141 of the heat sink 13 together form a housing space 175, that is, the first surface 141 of the heat sink 13 is adjacent to the lamp cover 17, and the second surface 142 of the heat sink 13 is away from the lamp cover 17. 100101777 Form No. A0101 Page 4 of 12 1002003165-0 201231864 [0011] The lamp cover 17 includes a fixing portion 172 and a cover portion 171. The cover portion 71 has a hemispherical shell shape. The cover portion 71 has a light incident surface 173 and a light exit surface 174 which are opposed to each other. The light incident surface 173 is located inside the cover portion 171 and faces the heat sink 13. The light exit surface 147 is located outside the cover portion 117 and is in direct contact with the outside. The fixing portion 172 has a circular shape, and the fixing portion 172 is formed to protrude radially outward from the outer edge of the cover portion 171. That is, the fixing portion 172 is formed to extend horizontally outward from the bottom end of the cover portion ι71. The shape and size of the fixing portion 172 correspond to the shape and size of the mounting groove 157, respectively. [0012] The LED module 16 is located above the first surface 141 of the heat sink 13 and is received in the receiving space 175. The light-emitting diode module 16 faces the light-incident surface 173 of the lamp cover 17 and the light emitted from the light-emitting diode module 16 enters the lamp cover 17 ′ through the light-incident surface 173 of the lamp cover ι 7 and finally exits the lamp cover via the light-emitting surface 174 of the lamp cover 17 . 17. [0013] When the lamp cover 17 is mounted on the heat sink 13, the fixing portion 172 of the lamp cover 17 abuts against the yoke surface 154 of the stop arm 153 of the heat sink 13, and the lamp cover 17' is fixed by the force of the lamp cover 17 The portion 2 causes the elastic arm 152 of the latching portion 151 of the heat sink 13 to open outwardly, and the fixing portion 172 of the lamp cover 17 moves downward along the guiding surface 154 of the stop arm 153 until entering the card slot 156, and the latching portion 1 The stop arm 153 of the latching portion 15 is pressed against the fixing portion 172 of the lamp cover 17, and the stop surface 155 of the elastic arm 152 and the fixing portion 172 are in contact with each other. The fixing portion 172 of the heat sink 13 is fastened to the first surface 141 of the heat sink 13 , that is, the plurality of fastening portions 151 of the heat sink 13 surround the lamp cover 17 and the lamp cover 17 The fixing portion 172 is pressed against the top end of the heat sink 13, so that the lamp cover 17 is tightly connected to the heat sink 13. The above-mentioned luminaire passes through the fixing portion of the lamp cover π 100101777 Form No. A0101 Page 5 / Total 12 pages 1002003165 201231864 172 The buckle portion 151 of the heat sink 13 is fastened and connected, and no additional auxiliary tools are required, and the disassembly and assembly is convenient. In addition, those skilled in the art can make other changes in the spirit of the present invention. For example, the heat sink 13 is provided with the fixing portion 172, and the lamp cover 17 is provided with the locking portion 151 as long as it does not deviate from the technical effects of the present invention. These variations, which are made in accordance with the spirit of the invention, are intended to be included within the scope of the invention.
