Description

Technical Field

[0001] This invention relates to an LED light source, and more particularly to a dimmable and color-adjustable GX53 light source. Background Technology

[0002] Compared to traditional light sources, LED light sources offer advantages such as high brightness and low power consumption. Due to the limited internal space of GX53 light source products, commonly available GX53 light sources cannot achieve dimming or color temperature adjustment, have low waterproof ratings, limited functionality, and are suitable for relatively fixed scenarios, resulting in poor versatility. Existing technologies, such as the Chinese patent document CN2021213705896 which discloses "A High-Efficiency LED GX53 Light Source," offer limited functionality, only supporting single power and single color temperature, without dimming or color temperature adjustment. When customers require GX53 light source products with different power or color temperatures, they must purchase different models, leading to low versatility, inconvenience, and poor waterproof performance.

[0003] Because different usage scenarios and different customers have different requirements for power, color temperature, and waterproof performance, if a customer needs different power levels of 5W, 7W, and 10W, then three different power versions of the product need to be developed. In addition, if a customer needs different color temperatures of 2700K, 3200K, and 4000K, then three different color temperature versions of the product need to be developed. According to the geometric progression, there are a total of nine options, that is, nine different models of products need to be developed to meet the needs of customers. This undoubtedly increases various costs such as development costs, material costs, and management costs, as well as the difficulty of choice for users. On the other hand, because the internal space of the GX53 light source is small, it is very difficult to achieve both dimming and color adjustment at the same time. Therefore, this patent solves this problem through precise design, achieving a universal product within a limited product space, while simultaneously improving waterproof performance. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a dimmable and color-tunable GX53 light source, which has dimming and color-tuning functions, can meet customers' requirements for different power and color temperature, and at the same time, in order to take into account material costs, the light source is designed in different sizes.

[0005] The technical solution adopted by this invention to solve the above-mentioned technical problems is as follows: When the power required by the light source is large, a dimmable and color-adjustable GX53 light source is provided. The main structure includes an adjustment knob, a driving power supply, a power supply housing, a heat sink, a lamp board, a pressure ring, a lamp cover, and several sealing rings. Two rotary switches are connected to the driving power supply. The power supply housing is integrally formed and consists of an upper truncated cone and a lower circular base. A knob mounting hole is provided on the upper side of the upper truncated cone for positioning the two adjustment knobs. The adjustment knobs correspond to the rotary switches and are used to adjust the power and color temperature. The driving power supply is installed in the inner cavity of the power supply housing by screws. The power supply housing is connected to the heat sink by screws. The advantage of this technical solution is that the light source can simultaneously have dimming and color-adjusting functions, which can meet the user's requirements for different power and color temperature, and has better waterproof and dustproof performance.

[0006] The adjustment knob has a stepped stop on its upper side, with an arrow indicator groove in the stepped stop. Below the stepped stop is a center positioning stop, and below the center positioning stop is a sealing ring installation stop. A sealing ring can be installed outside the sealing ring installation stop. Below the sealing ring installation stop is a stop, below the stop is a limit stop, and below the limit stop is a torsion transmission stop. The torsion transmission stop matches the groove in the center of the rotary switch, which can drive the rotary switch to rotate and change gears. A sealing ring can be added between the adjustment knob and the power supply housing as needed to improve the waterproof performance of the light source, thereby enabling dimming and color adjustment.

[0007] The driving power supply is installed in the inner cavity of the lower round bottom. The driving power supply board of the driving power supply is connected to two rotary switches, two GX53 copper pins, and other electronic components. One rotary switch is used to adjust the power and the other is used to adjust the color temperature. The adjustment knob corresponds to the rotary switch. The driving power supply converts the AC power input from the copper pins into DC power and supplies it to the lamp board. After the positioning notch on the driving power supply board is positioned with the screw post on the driving housing, it is installed in the inner cavity of the power housing with screws. The driving power supply and the lamp board are connected by a power cable passing through the wire hole of the heat sink and the wire hole of the lamp board, and then soldered to conduct electricity.

[0008] The power supply housing is integrally molded and consists of an upper truncated cone and a lower circular base. The upper truncated cone is installed after being centered with the external GX53 standard lamp holder. The upper truncated cone has a knob mounting hole, a sealing ring groove, and a screw post. The upper side of the upper truncated cone has a knob mounting hole for the power adjustment knob and the color temperature adjustment knob. The sealing ring groove contacts the sealing ring. The screw post is used to install the driver power supply. The driver power supply uses two screws, which pass through the screw hole and press against the screw post of the power supply housing. The lower circular base has a copper pin for positioning inside. The components include a hole, a sealing ring groove, an isolation layer, a screw post, and a pressure rib. The positioning hole for the copper pin is used to pass through the two GX53 copper pins on the drive power supply. The sealing ring groove is used to install the sealing ring to enhance the waterproof performance of the GX53 copper pin. The isolation layer is used to isolate the thermally conductive potting compound and prevent it from entering the rotary switch and causing it to malfunction. After the screw post of the lower round bottom is positioned with the positioning semi-circular groove on the heat sink, the screw is connected by passing the screw through the screw hole of the heat sink. The bottom of the lower round bottom has a pressure rib, which can press down the sealing ring installed in the sealing ring groove of the heat sink.

[0009] The heat sink is integrally molded, with heat dissipation ribs, three sealing ring grooves, and one positioning semi-circular groove on the back. The inner surface has three screw posts, one positioning square groove, four sealing ring grooves, two screw holes, and one wire passage hole. The positioning semi-circular groove is used to facilitate the positioning and assembly between the heat sink and the power supply housing. The three screw posts are used to position the lamp board and the pressure ring. The positioning square groove is used to facilitate the positioning and assembly between the heat sink and the lamp cover. The screw two passes through the screw hole two of the heat sink and is screwed into the screw post two of the power supply housing to fix the heat sink and the power supply housing. The back of the heat sink has a reserved sealing ring groove three for installing the sealing ring three, and the inner surface of the heat sink has a reserved sealing ring groove four for installing the sealing ring four. The sealing ring can be selected according to actual needs to improve the waterproof performance of the light source.

[0010] The lamp board has several LED beads of different color temperatures welded on it. There is a wire hole 2 in the middle and a positioning notch 2 on the outer circumference. After the positioning notch 2 is positioned with the screw post 3 on the heat sink, it is pressed onto the inner plane of the heat sink by the pressure ring 1. The heat sink is used to dissipate the heat generated when the light source is working. The lamp board 1 and the driving power supply 1 are connected by a power cable passing through the wire hole 1 of the heat sink and the wire hole 2 of the lamp board 1 and then welded together to conduct electricity.

[0011] The pressure ring has a buckle on the upper side of its outer circle and a positioning semicircular groove on its lower plane. There is a screw hole in the middle of the pressure ring. After the positioning semicircular groove on the pressure ring is positioned with the screw post on the inner surface of the heat sink, the screw passes through the screw hole and presses onto the screw post on the front of the heat sink. The buckle on the outer side of the pressure ring is fastened to the slot on the inner side of the lamp cover.

[0012] The lampshade has a positioning rib on the outer side and a slot on the inner side. The positioning rib matches and positions the lampshade with the positioning square groove on the inner surface of the heat sink, so that the lampshade will not rotate. The slot on the lampshade engages with the buckle on the pressure ring and is fastened. The bottom of the lampshade presses against the sealing ring.

[0013] When the dimmable and color-tunable GX53 light source does not require high power, i.e., the required power is relatively small, the main structure is designed as in Embodiment 2. In this embodiment, the power supply housing and the heat sink are integrated, i.e., the heat sink is eliminated and a power supply housing is formed as Embodiment 2. The product size can also be appropriately reduced. The main structure of Embodiment 2 includes an adjustment knob, a second driving power supply, a second power supply housing, a second lamp board, a second pressure ring, a second lamp cover, and several sealing rings. The second driving power supply is connected to two rotary switches. The second power supply housing is integrally formed and consists of an upper truncated cone and a lower circular base. The upper truncated cone has a knob mounting hole for mounting a power adjustment knob and a color temperature adjustment knob. The adjustment knob corresponds to the rotary switch and is used to adjust the power and color temperature. The second driving power supply is installed in the inner cavity of the second power supply housing. The second driving power supply is pressed onto the screw post of the second power supply housing by two screws passing through the screw hole.

[0014] The adjustment knob has a stepped stop on its upper side, with an arrow indicator groove in the stepped stop. Below the stepped stop is a center positioning stop, and below the center positioning stop is a sealing ring installation stop. A sealing ring can be installed outside the sealing ring installation stop. Below the sealing ring installation stop is a stop, below the stop is a limit stop, and below the limit stop is a torsion transmission stop. The torsion transmission stop matches the groove in the center of the rotary switch two, which can drive the rotary switch two to rotate and change gears. A sealing ring can be added between the adjustment knob and the power supply housing two as needed to improve the waterproof performance of the light source, thereby enabling dimming and color adjustment.

[0015] The driving power supply is connected to two rotary switches, two GX53 copper pins, and other components. The driving power supply and the lamp board are electrically connected by soldering pins or power cables. One rotary switch on the driving power supply is used to adjust the power, and the other is used to adjust the color temperature. The adjustment knobs correspond to the rotary switches. The driving power supply is secured to the power supply housing by two screws, which pass through screw holes and press into the screw posts. The driving power supply converts the AC power input from the GX53 copper pins into DC power and supplies it to the lamp board.

[0016] The power supply housing is integrally formed, consisting of an upper truncated cone and a lower circular base. The upper truncated cone is installed after being centered with the external GX53 standard lamp holder. The upper truncated cone has a knob mounting hole, a sealing ring groove, and a screw post. The knob mounting hole is the mounting position for the power adjustment knob and the color temperature adjustment knob. The sealing ring groove is used to install the sealing ring to improve the waterproof rating of the adjustment knob mounting point. The screw post is used to position the drive power supply. The lower circular base has a copper pin positioning hole, a sealing groove, a shim, and a positioning square inside. The groove 2, the card groove 2, and the sealing groove 7 are as follows: the positioning holes of the copper pins 2 on the lower round bottom 2 are used to pass through the two GX53 copper pins 2 on the driving power supply 2; the shim is used to raise the lamp board 2 so that the lamp board 2 can maintain a certain distance from the driving power supply 2; the positioning square groove 2 matches the positioning rib 2 on the lamp cover 2 so that the lamp cover 2 will not rotate; the card groove 2 is used to lock and connect with the buckle 2 on the lamp cover 2; the inner surface of the lower round bottom 2 has a reserved sealing groove 6 for installing the sealing ring 5 and a reserved sealing groove 7 for installing the sealing ring 6. The sealing rings are selected according to actual needs to improve the waterproof performance of the light source.

[0017] The lamp board 2 is welded with several LED beads of different color temperatures. The lamp board 2 and the driving power supply 2 are connected and conductive through a pin or power line. The lamp board 2 is pressed onto the pad block in the power supply housing 2 by the pressure ring 2. The lamp cover 2 has a positioning rib 2 and a buckle 2 on the outside, and a strong release and a top block on the inside. The positioning rib 2 on the lamp cover 2 matches and positions with the positioning square groove 2 on the power supply housing 2, so that the lamp cover 2 will not rotate. The buckle 2 on the lamp cover 2 is fastened after cooperating with the buckle 2 on the power supply housing 2. The pressure ring 2 is fastened between the strong release and the top block on the inside of the lamp cover 2.

[0018] When the convenience of manual adjustment of the light source is not a high requirement, the solution in Example 3 can be adopted, which eliminates the need for the adjustment knob. Only two rotary switches with handles need to be connected to the power supply. The upper truncated cone of the power supply housing retains the corresponding switch handle through hole. Since the handle diameter of the rotary switch is smaller than that of the adjustment knob, the rotary switch is not easy to operate compared to the adjustment knob, which will cause inconvenience to manual operation. At this time, additional tools such as small flathead screwdrivers are required.

[0019] When the light source only needs to adjust brightness or only needs to adjust color, in Embodiment 1, one adjustment knob and one sealing ring can be omitted, and one rotary switch can also be omitted from the drive power supply. At the same time, only one knob mounting hole is needed on the power supply housing. In Embodiment 2, one adjustment knob and one sealing ring can also be omitted, and one rotary switch can also be omitted from the drive power supply. At the same time, only one knob mounting hole is needed on the power supply housing. In Embodiment 3, only one rotary switch with a handle and one sealing ring are needed on the drive power supply. Correspondingly, only one switch handle protrusion hole is needed on the upper truncated cone of the power supply housing.

[0020] All the sealing rings in the above solutions are optional. When it is necessary to improve the waterproof and dustproof rating of the light source, sealing rings can be selectively installed in the reserved sealing ring grooves to meet the waterproof and dustproof performance requirements of different customers.

[0021] Compared with the prior art, the advantages of the present invention are as follows:

[0022] 1) In this solution, the light source can be easily adjusted to different power and color temperature in a small space by rotating the adjustment knob and driving the rotary switch. One product can meet the user's requirements for multiple different power and color temperature, and has strong versatility.

[0023] 2) This solution can be customized according to customer requirements, such as retaining only the color adjustment function or only the temperature adjustment function, which is highly flexible.

[0024] 3) This solution provides sealing ring grooves in different parts such as the power supply housing and heat sink, and reserves sealing ring installation positions. When the required IP waterproof and dustproof rating of the light source is high, sealing rings can be selectively added to different parts of the light source to enhance the waterproof and dustproof performance of the light source and meet the needs of the GX53 light source in different scenarios.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0060] Example 1:

[0061] like Figures 1-7 As shown, when the power required by the light source is large, a dimmable and color-adjustable GX53 light source mainly includes an adjustment knob 11, a driving power supply 12, a power supply housing 13, a heat sink 14, a lamp board 15, a pressure ring 16, a lamp cover 17, and several sealing rings. The driving power supply board 121 of the driving power supply 12 is connected to two rotary switches 122. The adjustment knob 11 and the rotary switches 122 correspond to each other to adjust the power and color temperature. The driving power supply 12 is installed in the inner cavity of the power supply housing 13 with screws 22. The power supply housing 13 is integrally formed and consists of an upper truncated cone 131 and a lower round bottom 132. The power supply housing 13 is connected to the heat sink 14 with screws 23. The upper truncated cone 131 has a knob mounting hole 1311 on its upper side for installing the power and color temperature adjustment knob 11. The advantage of this technical solution is that the light source can simultaneously have dimming and color-adjusting functions, which can meet the user's requirements for different power and color temperature.

[0062] like Figure 3As shown, the adjustment knob 11 has a stepped stop 111 on its upper side, an arrow indicator groove 1111 in the stepped stop 111, a center positioning stop 112 below the stepped stop 111, and a sealing ring mounting stop 113 below the center positioning stop 112. The sealing ring mounting stop 113 can be used to install the sealing ring 18 to improve the waterproof performance of the light source. Below the sealing ring mounting stop 113 is a stop 114, below the stop 114 is a limit stop 115, and below the limit stop 115 is a torsion transmission stop 116. The torsion transmission stop 116 matches the groove in the center of the rotary switch 122, which can drive the rotary switch 122 to rotate and change gears, thereby adjusting the brightness and color.

[0063] like Figures 2-10 As shown, the driving power supply 12 is installed in the inner cavity of the lower round bottom 131. The driving power supply board 121 of the driving power supply 12 has two rotary switches 122, two GX53 copper pins 123 and other components connected to it. The driving power supply board 121 has screw holes 1211 and positioning notches 1212. After the positioning notches 1212 match and are positioned with the screw post 1324, the driving power supply 12 is pressed onto the screw post 1313 of the power supply housing 13 by screws 22 passing through screw holes 1211. The driving power supply 12 and the lamp board 15 are connected by a power cable passing through wire holes 148 and 1511 and then soldered to conduct electricity. The two DIP switches 122 on the driving power supply 12 are used to adjust the power and the other to adjust the color temperature. The adjustment knob 11 corresponds to the rotary switch 122.

[0064] like Figures 6-15As shown, the power supply housing 13 is integrally formed, consisting of an upper truncated cone 131 and a lower circular base 132. The upper truncated cone 131 of the power supply housing 13 is centered with the external GX53 standard lamp holder. The upper truncated cone 131 has a knob mounting hole 1311, a sealing ring groove 1312, and a screw post 1313. The knob mounting hole 1311 is used to install the power adjustment knob 11 and the color temperature adjustment knob 11. The sealing ring groove 1312 is used to install the sealing ring 18. The drive power supply 12 is driven by a screw 22, which passes through the screw hole 1211 and presses onto the screw post 1313 of the power supply housing 13. The screw post 1324 of the lower circular base 132 is positioned with the positioning semicircular groove 143 on the heat sink 14 and then screwed in. The lower round bottom 132 has a copper pin positioning hole 1321, a sealing ring groove 1322, an isolation layer 1323, a screw post 1324, and a pressure rib 1325. The copper pin positioning hole 1321 is used to pass through the two GX53 copper pins 123 on the drive power supply 12. The sealing ring groove 1322 is used to install the sealing ring 19 to enhance the waterproof performance of the GX53 copper pins 123. The isolation layer 1323 is used to isolate the thermally conductive potting compound and prevent it from entering the rotary switch 122 and causing the switch to fail. The screw post 1324 is used to connect with the heat sink 13. The bottom of the lower round bottom 132 has a pressure rib 1325, which can press down the sealing ring 20 in the sealing ring groove 142 of the heat sink 14.

[0065] like Figures 8-15 As shown, the heat sink 14 is integrally formed, with heat dissipation ribs 141, sealing ring groove 142, and positioning semi-circular groove 143 on the back, and screw posts 144, positioning square groove 145, sealing ring groove 146, screw holes 147, and wire holes 148 on the inner surface. The heat dissipation ribs 141 are used to dissipate the heat of the GX53 light source during operation. The positioning semi-circular groove 143 is used to facilitate the positioning connection between the heat sink 14 and the power supply housing 13. The screw posts 144 are used to position the lamp board 15 and the pressure ring 16.

The pressure ring 28 is fastened between the strong release buckle 293 and the top block 294 on the inner side of the lampshade 29.

[0075] Example 3:

[0076] like Figures 26-30As shown, when the convenience of manual adjustment of the GX53 light source is not high, the solution of Embodiment 3 can be adopted. That is, the adjustment knob 11 and the sealing ring 18 can be eliminated. Two rotary switches 332 with handles and two GX53 copper pins 333 are connected to the drive power board 331 of the drive power supply 33. The rotary switches 332 replace the rotary switches 122 in the original drive position and are replaced with the sealing ring 7 34. The corresponding switch handle through hole 3511 is retained on the upper truncated cone 351 of the corresponding power housing 35. The structure of the lower round bottom 352 is the same as that of the lower round bottom 132. In this Embodiment 3, since the handle diameter of the rotary switch 332 with handle is smaller than that of the adjustment knob 11, the rotary switch 332 is not easy to operate compared to the adjustment knob 11. The convenience of manual adjustment is reduced compared to Embodiment 1 and Embodiment 2, but the cost is also reduced. Embodiment 3 has a greater cost advantage than Embodiment 1.

[0077] The above are detailed descriptions of three embodiments. When the light source only needs to adjust brightness or only needs to adjust color, for Embodiment 1, one adjustment knob 11 and one sealing ring 18 can be reduced, and one rotary switch 122 can also be reduced on the drive power supply 12. Only one knob mounting hole 1311 needs to be retained on the power supply housing 13. For Embodiment 2, one adjustment knob 11 and one sealing ring 18 can be reduced, and one rotary switch 252 can also be reduced on the drive power supply 25. Only one knob mounting hole 2611 needs to be retained on the power supply housing 26. For Embodiment 3, only one rotary switch 332 with a handle and one sealing ring 34 need to be connected to the drive power supply 33. Only one switch handle protrusion hole 3511 needs to be retained on the corresponding power supply housing 35.

[0078] All the sealing rings in the above solutions are optional. When it is necessary to improve the waterproof and dustproof rating of the light source, sealing rings can be selectively installed in the reserved sealing ring grooves to meet the waterproof and dustproof performance requirements of different customers.

[0079] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. When the technical features of different embodiments are embodied in the same drawing, it can be regarded that the drawing also discloses the combination examples of the various embodiments involved.

[0080] The above embodiments are merely illustrative of several implementation methods of this application, and their descriptions are quite specific and detailed. However, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
