Description

Technical Field

[0001] This invention belongs to the field of LED lamp holder technology, specifically relating to an LED lamp holder. Background Technology

[0002] Traditional LED light sources often emit only a single brightness or color of light. To enable dimming or color adjustment, a dimming or color adjustment switch is usually installed on the lamp body. For example, a switch hole is installed on the lamp body of bulbs, PAR lamps, and BR lamps, an adjustment switch is installed inside the lamp body, and a switch panel is installed outside the lamp body. The switch panel passes through the switch hole and is connected to the adjustment switch. The brightness or color temperature of the lamp is adjusted by adjusting the switch panel. Another example is filament lamps. To achieve dimming or color adjustment, a plastic connector is installed between the bulb and the lamp base. A switch adjustment component is installed outside the plastic connector, and an adjustment switch is installed on the driver power supply. The switch adjustment component is connected to the adjustment switch, and the brightness or color temperature is adjusted by changing the position of the adjustment switch through the switch adjustment component.

[0003] The aforementioned switch placement will, on the one hand, damage the shape and structure of the lamp body or the entire lamp, increase production difficulty, and affect the overall aesthetics; on the other hand, for light sources that need to be waterproof when installed outdoors, such as PAR lamps, the placement of the switch on the lamp body will also prevent the PAR lamp from being waterproof, thus making the PAR lamp unsuitable for outdoor locations that require waterproofing.

[0040] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0041] Example: An LED lamp holder, such as Figures 1-16 As shown, it includes a metal casing 1, a mounting component 14 disposed inside the metal casing 1, rivets 24 disposed on the mounting component 14, and an adjustment component. The adjustment component includes an adjustment member 2 disposed on the upper part of the metal casing 1 and a connecting part 3 disposed inside the mounting component 14 mounted in the metal casing 1. The adjustment member 2 is connected to a switch 5 through the connecting part 3. By rotating the adjustment member 2, the connecting part 3 is rotated to change the position of the switch 5 to adjust the color temperature or brightness of the LED light source.

[0042] In this embodiment, switch 5 can be directly mounted on the LED light source driver power supply board 23 and electrically connected to the driver power supply board 23; alternatively, it can be mounted separately on an adapter board, which is electrically connected to the driver power supply via pin headers or wires. When switch 5 is directly mounted on the driver power supply board 23, it can be placed horizontally or vertically depending on the position of the driver power supply board 23, thus allowing the switch handle 4 of switch 5 to be placed horizontally or vertically. Switch 5 can be a toggle switch or other adjusting switch.

[0043] In this embodiment, the adjusting component and the mounting component 14 are made of insulating material. For example... Figures 4-7As shown, the mounting component 14 is a cylindrical structure that matches the metal casing 1. One end of the mounting component 14 is closed, and the other end is open to form a receiving cavity. A protrusion 26 for mounting a rivet 24 is provided at the center of one end of the mounting component 14. The protrusion 26 is cylindrical and has a first through hole 27, which communicates with the receiving cavity of the mounting component 14. The metal casing 1 is a hollow structure with openings at the top and bottom. When the mounting component 14 is installed inside the metal casing 1, the protrusion 26 on the mounting component 14 passes through the opening at the top of the metal casing 1 and extends to the top of the metal casing 1. The rivet 24 is mounted on the protrusion 26 of the mounting component 14 by inserting its lower end into the first through hole 27. To prevent the rivet 24 from loosening, multiple protruding first ribs 18 are symmetrically arranged circumferentially inward on the inner wall of the first through hole 27, and the first ribs 18 are vertically arranged. The clamping fit between the first ribs 18 can clamp the lower end of the rivet 24 to prevent the rivet 24 from coming out of the first through hole 27; at the same time, the gap between two adjacent first ribs 18 allows the input live wire to run and is electrically connected to the lower end of the rivet 24.

[0044] The mounting component 14 has a mounting hole 15 on its outer wall at one end. The mounting hole 15 is located on the outer periphery of the protrusion 26 and has an arc-shaped structure.

[0045] The adjusting component 2 is a hollow frustum structure. The adjusting component 2 and the connecting part 3 can be connected as one piece or as separate pieces.

[0046] When the adjusting member 2 and the connecting part 3 are integrally connected, that is, when one end of the adjusting member 2 is connected to one end of the connecting part 3 to form an integral part, the connecting part 3 is an arc-shaped structure adapted to the mounting hole 15. The other end of the connecting part 3 passes through the mounting hole 15 on the mounting component 14 and connects to the switch handle 4 of the switch 5. The switch 5 and the drive power board 23 are both located in the receiving cavity at the other end of the mounting component 14.

[0047] like Figure 2 , Figure 3 , Figure 7 As shown, when the switch handle 4 of switch 5 is placed horizontally, the other end of the connecting part 3 has a U-shaped structure and forms a notch 6, which is inserted into the switch handle 4 of switch 5. When the adjusting member 2 rotates, the connecting part 3 rotates along the mounting hole 15 and uses the notch 6 to move the switch handle 4 of switch 5 to change the position of the switch handle 4 on switch 5, so as to realize the adjustment of the switch 5 gear, thereby realizing the adjustment of the color temperature or brightness of the LED light source.

[0048] When the switch handle 4 of switch 5 is placed vertically, since the side spacing of the switch handle 4 of switch 5 is small, in order to prevent the U-shaped notch 6 at the other end of the connecting part 3 from detaching after being inserted into the switch handle 4, an adapter 7 is added.

[0049] like Figures 9-11 As shown, the upper end of the adapter 7 is provided with a groove 8 for inserting the other end of the connecting part 3, and the lower end of the adapter 7 is provided with a cavity 9 for fitting the switch handle 4 of the switch 5. In this embodiment, the upper end of the adapter 7 is a square structure, the groove 8 is located on the square structure, and the groove opening and one of the groove walls of the groove 8 are open; the lower end of the adapter 7 is a columnar structure, and the cavity 9 is located on the columnar structure. Of course, the adapter 7 can also have other structures, such as both the upper and lower ends of the adapter 7 being hollow columnar structures, with the other end of the connecting part 3 and the switch handle 4 of the switch 5 respectively fitted onto the upper and lower hollow columnar structures of the adapter 7.

[0050] In use, the other end of the connecting part 3 is inserted into the groove 8 at the upper end of the adapter 7, and the switch handle 4 of the switch 5 is fitted into the cavity 9 at the lower end of the adapter 7. When the adjusting part 2 rotates, the connecting part 3 rotates along the mounting hole 15, and the adapter 7 is used to move the switch handle 4 of the switch 5 to change the position of the switch handle 4 on the switch 5, so as to realize the adjustment of the switch 5 gear, thereby realizing the adjustment of the color temperature or brightness of the LED light source.

[0051] like Figures 13-16 As shown, when the adjusting component 2 and the connecting part 3 are separately connected, one end of the adjusting component 2 is connected to the mounting post 10 to form a whole, and the connecting part 3 is connected to the mounting plate 11 to form a whole. The connecting part 3, the mounting plate 11, the switch 5, and the drive power board 23 are all located in the receiving cavity at the other end of the mounting component 14. The adjusting component 2 and the connecting part 3 are connected by the mounting post 10 passing through the mounting hole 15 on the mounting component 14 and connecting to the mounting plate 11. Specifically:

[0052] The mounting plate 11 has a through hole 12 that matches one end of the mounting post 10. The mounting post 10 and the mounting plate 11 are connected by inserting one end of the mounting post 10 into the through hole 12. The number of mounting posts 10 and mounting holes 15 can be set according to requirements. The mounting posts 10 and mounting holes 15 can be connected by an interference fit to prevent the mounting posts 10 and the mounting plate 11 from detaching. The mounting plate 11 has a second through hole 28 at its center. The input live wire passes through the second through hole 28 and the first through hole 27 and is electrically connected to the lower end of the rivet 24.

[0053] The connecting part 3 has a groove-shaped structure and forms a slot 13. The switch handle 4 of the switch 5 is placed vertically and inserted into the slot 13 of the connecting part 3. When the adjusting member 2 rotates, the mounting post 10 rotates with the adjusting member 2 and drives the mounting plate 11 to rotate synchronously. The rotation of the mounting plate 11 causes the connecting part 3 to rotate, and the connecting part 3 is used to move the switch handle 4 of the switch 5 to change the position of the switch handle 4 on the switch 5, so as to realize the adjustment of the switch 5 level, thereby realizing the adjustment of the color temperature or brightness of the LED light source.

[0054] When the mounting component 14 is installed inside the metal housing 1, the adjusting member 2 is located above the metal housing 1, and its lower end abuts against the upper opening of the metal housing 1. Figure 2 , Figure 3 , Figure 7 , Figure 11 As shown, when one end of the adjusting member 2 is connected to one end of the connecting part 3 to form a single unit, the other end of the connecting part 3 passes through the opening at the top of the metal housing 1 and the mounting hole 15 on the mounting member 14, and extends into the receiving cavity of the mounting member 14, connecting to the switch handle 4 of the switch 5 located in the receiving cavity of the mounting member 14. At this time, one end of the adjusting member 2 is provided with a locking part 16, the end of which passes through the opening at the top of the metal housing 1 and the mounting hole 15 on the mounting member 14, and extends into the receiving cavity of the mounting member 14, abutting against the inner wall of one end of the mounting member 14. The locking part 16 can rotate within the mounting hole 15. When the adjusting member 2 rotates, it drives the locking part 16 to rotate synchronously within the mounting hole 15.

[0055] There can be one or more snap-fit ​​parts 16. When there are multiple snap-fit ​​parts 16, the connection between the snap-fit ​​parts 16 and the mounting component 14 is relatively stable through the abutting fit between the ends of the multiple snap-fit ​​parts 16, making it difficult for the snap-fit ​​parts 16 to detach from the mounting hole 15, thereby connecting the adjusting member 2, the metal housing 1 and the mounting component 14 together, and preventing the adjusting member 2 from detaching from the opening at the top of the metal housing 1.

[0056] When there is only one locking part 16, the end of the locking part 16 passes sequentially through the opening at the top of the metal housing 1, the mounting hole 15 on the mounting component 14, and extends into the receiving cavity of the mounting component 14, abutting against the inner wall of one end of the mounting component 14. Simultaneously, a locking block 17 is provided on the connecting part 3. The locking block 17 is located within the receiving cavity of the mounting component 14 and abuts against the inner wall of one side of the mounting component 14. By providing the locking block 17 on the connecting part 3 and cooperating with the locking part 16, the connection stability between the adjusting member 2 and the mounting component 14 can be improved, ensuring that the adjusting member 2, the metal housing 1, and the mounting component 14 are connected together, preventing the adjusting member 2 from detaching from the opening at the top of the metal housing 1.

[0057] like Figures 13-16 As shown, when the adjusting member 2 and the connecting part 3 are connected separately, one end of the mounting post 10 connected to the adjusting member 2 passes through the opening above the metal shell 1 and the mounting hole 15 on the mounting part 14 in sequence, and extends into the receiving cavity of the mounting part 14. After being inserted through the through hole 12, it is riveted to the bottom of the mounting plate 11 to achieve connection with the mounting plate 11, so that the adjusting member 2, the metal shell 1 and the mounting part 14 are connected together, and the adjusting member 2 is prevented from detaching from the opening above the metal shell 1.

[0058] like Figure 7, Figure 11 , Figure 16 As shown, when the mounting component 14 is installed inside the metal housing 1, the protrusion 26 on the mounting component 14 passes through the upper opening of the metal housing 1 and the adjusting member 2 in sequence. The rivet 24 is then installed on the protrusion 26 of the mounting component 14 through the insertion fit of the rivet 24 and the first through hole 27, thus connecting the rivet 24, the adjusting member 2, the metal housing 1, and the mounting component 14. The mounting component 14 is installed inside the metal housing 1 with an interference fit, and one end of the adjusting member 2 abuts against the upper opening of the metal housing 1. When the adjusting member 2 rotates, it rubs against the upper opening of the metal housing 1. To prevent loosening between the metal housing 1 and the mounting component 14 due to friction between the adjusting member 2 and the metal housing 1, multiple protruding second ribs 19 are symmetrically arranged outwards circumferentially on the outer wall of the mounting component 14, and the second ribs 19 are vertically arranged. Figure 4 As shown; by setting the second rib 19, the frictional resistance between the metal shell 1 and the mounting component 14 is increased, achieving an anti-loosening effect between the metal shell 1 and the mounting component 14, and fixing the metal shell 1 and the mounting component 14 together with the interference fit. Alternatively, an external thread 20 matching the internal thread inside the metal shell 1 can be provided on the outer wall of the mounting component 14, such as... Figure 6 As shown, the mounting component 14 is installed inside the metal housing 1 by engaging the external thread 20 with the internal thread inside the metal housing 1, which can also prevent loosening and, together with the interference fit, fix the metal housing 1 and the mounting component 14 in place.

[0059] The outer wall of the adjustment component 2 is provided with an indicator arrow 21, and the metal housing 1 is provided with an identification mark 22 for identifying color temperature or brightness. The indicator arrow 21 corresponds to the identification mark 22, that is, when the indicator arrow 21 points to the corresponding identification mark 22, the current color temperature or brightness is displayed.

[0060] like Figure 1 , Figure 2 As shown, the upper part of the metal casing 1 is provided with a color temperature identification mark 22. When it is 30, 40 and 50, it corresponds to a color temperature of 3000K, 4000K and 5000K respectively. When the indicator arrow 21 points to 30, the LED light source displays a color temperature of 3000K. When the indicator arrow 21 points to 40, the LED light source displays a color temperature of 4000K. When the indicator arrow 21 points to 50, the LED light source displays a color temperature of 5000K.

[0061] When the upper part of the metal casing 1 is provided with brightness identification marks 22, which are 30, 50, 80 and 100, they correspond to 30% brightness, 50% brightness, 80% brightness and 100% brightness respectively; when the indicator arrow 21 points to 30, the LED light source displays a brightness value of 30%; when the indicator arrow 21 points to 50, the LED light source displays a brightness value of 50%; when the indicator arrow 21 points to 80, the LED light source displays a brightness value of 80%; when the indicator arrow 21 points to 100, the LED light source displays a brightness value of 100%.

[0062] During adjustment, the side wall surface of the adjustment component 2 can be rotated by hand to make the indicator arrow 21 point to the corresponding identification mark 22 for color temperature or brightness adjustment; alternatively, multiple longitudinal grooves 25 can be provided on the side wall surface of the adjustment component 2, and the adjustment component 2 can be rotated by inserting a tool into the longitudinal grooves 25 to make the indicator arrow 21 point to the corresponding identification mark 22 for color temperature or brightness adjustment.

[0063] Finally, it should be noted that the above embodiments are merely representative examples of the present invention. Obviously, the present invention is not limited to the above embodiments and many variations are possible. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention should be considered within the protection scope of the present invention.
