The main lighting LED 402 is arranged in a plurality of concentric circle arrays, and the night light LED 403 is arranged in a circular array and surrounds the outer periphery of the array of the main lighting LED 402. The back of the mounting plate 401 is connected with an input line 1, which is welded and connected to the mounting plate 401 and is electrically connected to the main lighting LED 402 and the night light LED 403.

[0041] like Figure 5 As shown, the heat dissipation lamp body 3 is a shell with one end open, the light source module 4 is assembled in the heat dissipation lamp body 3, and the mounting plate 401 and the back plate of the heat dissipation lamp body 3 are fixedly connected by fasteners 2, such as fastening screws, and the side with the LED mounted faces the open end of the heat dissipation lamp body 3, that is, the front end of the heat dissipation lamp body 3. The back plate of the heat dissipation lamp body 3 is provided with a wire hole, and the input line 1 passes through the wire hole.

[0042] like Figure 6 As shown, a front ring 12 is installed at the front end of the heat dissipation lamp body 3 , and an annular waterproof groove 1201 is provided on the front ring 12 , and an O-ring 11 for waterproof sealing is assembled in the waterproof groove 1201 .

[0043] like Figure 7 As shown, the optical module includes a reflector cup 6, a night light translucent cover 7, a main lighting translucent cover 8, a silicone gasket 9 and a fixing ring 10. A plurality of studs 1001 are arranged at intervals along the circumferential direction on one side of the fixing ring 10. The inner and outer diameters of the silicone gasket 9 match those of the fixing ring 10. The silicone gasket 9 is also provided with a through hole for the studs 1001 to pass through. Therefore, the silicone gasket 9 is installed on the fixing ring 10 by one-to-one sleeves on the studs 1001, which can avoid circumferential and radial movement of the silicone gasket 9. The main lighting translucent cover 8 is circular, and a first annular positioning step 801 is provided on its outer diameter surface. The outer circumferential surface of the first annular positioning step 801 can cooperate with the inner circle of the fixing ring 10 and the silicone gasket 9, and rest on the inner edge of the silicone gasket 9. The night light translucent cover 7 is annular, and its inner diameter is provided with a second annular positioning step 701, and its outer diameter is provided with a radial flange 702. The outer peripheral surface of the second annular positioning step 701 can cooperate with the outer circle of the fixing ring 10 and the silicone gasket 9, and rest on the outer edge of the silicone gasket 9.

[0044] like Figure 8 As shown, the reflector cup 6 is in the shape of a ring with a certain axial length, and the reflector cup 6 includes an outer cylindrical surface 601, an inner conical surface 602, and a front end surface 603 arranged at the front end for connecting the cylindrical surface 601 and the conical surface 602. Due to the inclination of the conical surface 602, the conical surface 602 encloses a main lighting light-transmitting area with a diameter expanding from back to front, and corresponds to the main lighting light-transmitting cover 8. The annular groove 604 between the cylindrical surface 601 and the conical surface 602 is used to separate the main lighting light on the inside and the small night light light on the outside. A fixing hole is arranged on the front end surface 603 in the annular groove 604, and a fastener 2 such as a fastening screw is passed through the fixing hole to connect with the stud 1001 on the fixing ring 10, and the silicone gasket 9 is pressed to form a seal.

[0045] Furthermore, the front end face 603 and the end of the cylindrical surface 601 and the end of the conical surface 602 form a recessed groove, which can form a convex-concave fit with the inner circumference of the second annular positioning step 701 on the night light translucent cover 7 and the inner circumference of the first annular positioning step 801 of the main lighting translucent cover 8. By controlling the depth of the recessed groove, the degree of extrusion of the silicone gasket 9 can also be changed to achieve the best sealing effect.

[0046] Further, such as Fig. 9 As shown, a circumferentially extending outer diameter groove 703 is provided on the radial flange 702 of the night light translucent cover 7, and the outer diameter groove 703 is engaged and fixed with the waterproof groove 1201 of the front ring 12, thereby realizing the installation connection between the front ring 12 and the night light translucent cover 7, and can squeeze the O-ring to further improve the sealing and waterproof effect.

[0047] like Figure 1 As shown, the outer peripheral surface of the front ring 12 is also provided with a threaded hole, the optical module with the front ring 12 installed is installed from the front end of the heat dissipation lamp body 3, and the heat dissipation lamp body 3 and the front ring 12 are connected and fixed together by fastening screws, as shown in FIG. Fig.10 After connection, Figure 2 As shown, the light of the main lighting LED 402 in the light source module is emitted from the main lighting transparent cover 8, and the light of the night light LED 403 is emitted from the night light transparent cover 7. In addition, the fastener 2 on the light source module and the welding point of the input line 1 are located in the annular groove 604 of the reflector cup 6, so that the rear end of the reflector cup 6 can be closely fitted with the mounting plate 401, thereby improving the light uniformity of the product.

[0048] like Figure 3 As shown, a spring 5 is also provided on the outer side of the heat dissipation lamp body 3 for installing and fixing the entire lamp.

[0049] Further, such as Fig.11As shown, the surface of the lamp, such as the surface of the heat dissipation lamp body, the main lighting translucent cover, the night light translucent cover and the surface of the front ring, is coated with an antibacterial coating 13, which is a modified super-hydrophilic nano-scale silica resin, and nano-scale ceramic particles that can slowly release silver ions are dispersed inside. After the coating is cured, it is a pure inorganic component, non-toxic and harmless, has an ultra-high hardness (10H, Japan Mitsubishi pencil test) and a wear resistance of more than 100,000 times, and has the characteristics of easy cleaning and anti-fingerprint. The surface oil and stains can be easily wiped off after wetting with water without the help of a cleaning agent. The surface treated with the antibacterial coating 13 has a super fast-acting antibacterial effect; it achieves super antibacterial ability, with an antibacterial activity value of >4.7 for Escherichia coli and >4.55 for Staphylococcus aureus.

[0050] Example 2

[0051] This embodiment proposes structural optimization of the drive control device based on the first embodiment.

[0052] like Fig.12 , 13 As shown, the drive control device includes a control box 14 , a power supply housing 15 , a control module and a power supply housing upper cover 17 .

[0053] like Fig.14 As shown, the control module includes a control board 19, a night light control module 16 and a main lighting control module 18. The pins of the night light control module 16 are welded on the control board 19, and the pins of the main lighting control module 18 are welded on the control board 19.

[0054] like Fig.15 As shown, the power supply housing 15 is made of plastic, and a partition 1501 is provided therein, which divides the space inside the power supply housing 15 into two parts, respectively accommodating the control board 19 and the main lighting control module 18. Gaps are left at both ends of the partition 1501 for the power supply wires to pass through. A threading hole is left on the side of the space accommodating the control board 19, so that the wires on the control board 19 can pass through the power supply housing 15. A threading hole is left on the side of the space accommodating the main lighting control module 18, so that the wires of the main lighting control module 18 can pass through the power supply housing 15. Buckles 1502 are also provided on the opposite sides of the space accommodating the main lighting control module 18, and the buckles 1502 are buckled on the upper edge of the main lighting control module 18 to fix the main lighting control module 18 in the power supply housing 15. The control board 19 can be fixed to the bottom of the power supply housing 15 by the fastener 2.

[0055] like Fig.12 , 13As shown, the control box 14 includes a box body 1401 and a flip cover 1402. The top of the box body 1401 is open, and one side of the flip cover 1402 is rotatably connected to one end of the top of the box body 1401. The length of the flip cover 1402 is less than the length of the box body 1401. Specifically, the sum of the length of the flip cover 1402 and the length of the power supply shell 15 is equal to the length of the box body 1401. Therefore, Fig.16 As shown, when the power supply shell 15 is placed in the box body 1401 of the control box 14 and away from the flip cover 1402, in order to prevent the power supply shell 15 from shaking back and forth in the box body 1401, a positioning plate 1503 is also connected to the rear end of the power supply shell 15. After the power supply shell 15 is loaded into the box body 1401, the positioning plate 1503 is pressed against the rear wall of the box body 1401. The setting of the positioning plate 1503 can also separate the wiring space in the control box 14 where the power supply shell 15 is not placed to the left and right, and divide it into a strong power wiring area 1404 and a dimming light wiring area 1405. The two wiring areas separated to the left and right can be routed and wired separately to avoid mutual influence and improve the safety of the product. Therefore, the main light source AC input line 1801 and the night light AC input line 1601 on the power supply shell 15 are arranged on one side of the power supply shell 15 and are located in the strong power wiring area 1404. The main light source dimming line 1802 and the night light dimming line 1602 on the power supply housing 15 are arranged on the other side of the power supply housing 15 and are located in the dimming line wiring area 1405. When wiring, a plurality of knockout holes are also arranged on the side of the box body 1401 of the control box 14, and the AC input line and the dimming line are wired through the knockout holes.

[0056] Furthermore, the upper portion of the box body 1401 is also provided with an outwardly protruding spring piece 1403, which is used to buckle the power shell 15. The power shell upper cover 17 is provided with fixing holes 1701 on opposite sides, and the spring piece 1403 is stuck in the fixing hole 1701 to fix the power shell upper cover 17.

[0057] It is understandable that, in other embodiments, the spring piece 1403 may be disposed on the power housing upper cover 17 , and the fixing hole 1701 may be disposed on the box body 1401 , which may also serve to buckle and fix the power housing upper cover 17 and the box body 1401 .

[0058] It should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention is described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
