[0022] Therefore, the following detailed description of the embodiments of the present invention provided in conjunction with the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0023] like Figures 1-6 As shown, the deep-light LED downlight in this embodiment is composed of a base part 10, a light-emitting part disposed in the base part 10, and an external driver 30. The driver 30 of the lamp is electrically connected to the light-emitting part through a power line. The base part 10 includes a cylindrical body 11, a retaining spring 111 is provided on the side of the cylindrical body 11, and a tail cap assembly 16 is provided on the top of the cylindrical body 11.
[0024] Specifically, a fixing ring 12 and a lamp cup 13 are provided inside the cylinder body 11. The lamp cup 13 opens towards the lower part of the cylinder body 11. An outer ring 14 is also provided at the lower opening of the cylinder body 11, as well as a heat sink 15 inside the cylinder body 11.
[0025] Furthermore, the light-emitting part includes a lamp plate 21, a reflector bowl 22, a lens 23, and an inner ring 24 arranged in sequence. LED beads are arranged on the lamp plate 21 facing the lens 23. The inner ring 24 is used to support the lamp plate 21 and the lens 23. The lamp cup 13 is arranged below the lens 23. The reflector bowl 22 is attached to the upper side of the lens 23. The fixing ring 12 is used to support the lamp cup 13. The fixing ring 12 is hung below the inner ring 24. The straight-line distance between the lens 23 and the lower opening of the cylinder 11 is greater than 1 / 3 of the length of the cylinder 11, realizing a hidden deep light source structure.
[0026] The inner ring 24 has multiple protruding plates 241 and hook bodies 242 along its edge. The protruding plates 241 have a positioning step 243 on their inner side, and the hook bodies 242 have a slot 244 on their inner side. The edge of the lamp plate 21 is positioned on the positioning step 243 and located in the slot 244. The lamp plate 21 is positioned below the heat sink 15, and the structure of the protruding plates 241 and hook bodies 242 provides support for the lamp plate 21.
[0027] Meanwhile, a connecting groove 245 is provided around the central opening of the inner ring 24. The lens 23 partially passes through the central opening, and a connecting protrusion 231 is provided on the edge of the lens 23. The connecting protrusion 231 and the connecting groove 245 are inserted and engaged, and both are distributed in a ring-shaped trajectory.
[0028] Two extension plates 246 are provided below the inner ring 24. The extension plates 246 are provided with inwardly protruding positioning pins 247. The side of the fixing ring 12 is provided with positioning holes 121. The positioning pins 247 and the positioning holes 121 are inserted and engaged to achieve a hanging engagement.
[0029] Multiple support protrusions 131 are provided on the outer wall of the lamp cup 13. The inner ring 24 is sleeved on the lamp cup 13 and abuts against the upper end face of the support protrusions 131. Multiple fastening bodies 141 are provided on the outer ring 14. The fastening bodies 141 are fastened to the lower end of the fixing ring 12. The lower end of the lamp cup 13 abuts against the inner side of the outer ring 14. The lamp cup 13 is clamped and fixed by the inner ring 24 and the outer ring 14.
[0030] It should be noted that the size of the outer ring 14 can be increased. For example, the outer diameter of the outer ring 14 can be 1.5-3 times the outer diameter of the cylinder 11. Therefore, when the mounting hole on the ceiling is damaged or the mounting hole is enlarged, the mounting hole can still be covered by the outer ring 14 to maintain the aesthetics.
