Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to an LED tube with adjustable power and color temperature. Background Technology

[0002] With the advancement of lighting technology, dimmable LED luminaires are increasingly favored for their ability to provide suitable illumination for different scenarios. To achieve adjustment of light intensity or color temperature, existing technologies typically incorporate toggle switches on the end caps of LED luminaires. These switches are electrically connected to the internal circuit board, allowing users to manually adjust the power or color temperature of the LED chips. For example, the LED straight tube lamp in Chinese Patent Publication No. "CN221348849U" uses two sets of toggle switches to control power and color temperature respectively.

[0003] However, currently, the light-emitting unit of the lamp usually needs to be fixed to the lamp tube or profile body, and the adjustment lever needs to be installed separately on the switch of the end cover. Finally, the end cover is combined with the main body. The whole process involves many parts and complicated steps, and requires high alignment accuracy, which seriously affects the ease of assembly.

[0004] Therefore, in order to further improve the ease of assembly of existing adjustable lighting fixtures, we propose an LED tube with adjustable power and color temperature. Utility Model Content

[0016] Furthermore, the inner side of the paddle is formed with a sleeve and two elastic arms;

[0017] The sleeve enters along the slide groove and the clearance opening, and is fitted onto the toggle block end of the toggle switch. The outer side of the elastic arm is formed with a locking protrusion. The two elastic arms pass through the slide groove, and the locking protrusion stops on the inner side of the profile body.

[0018] Furthermore, a socket is embedded on the end face of the end cap, and the socket is electrically connected to the color temperature adjustment module.

[0019] Furthermore, the socket includes a positive terminal, a negative terminal, and a grounding terminal;

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0032] Reference Figure 1-7 As one embodiment of this utility model, it discloses an LED tube with adjustable power and color temperature. Specifically, the tube includes a profile body 1 and an insulating tube 2 installed in the profile body 1. The profile body 1 is made of aluminum profile, which has good heat dissipation capacity and can achieve good heat dissipation for internal electrical components. Of course, in order to further optimize the heat dissipation effect, a heat dissipation part 14 is formed on the outside of the profile body 1 in this embodiment. The heat dissipation part 14 is set as heat dissipation fins. This method is a conventional method for those skilled in the art and will not be described in detail here.

[0033] The color temperature adjustment module 3 is fixedly installed inside the insulating tube 2. Specifically, in this embodiment, the insulating tube 2 is set as a plastic tube to serve as insulation and support. A light-emitting unit 4 is detachably connected to the top of the insulating tube 2.

[0034] The profile body 1 is further fitted with end caps 5 at both ends, and at least part of the end caps 5 stops at the side end of the light-emitting unit 4. A lever 6 is also slidably connected to the outside of the profile body 1, and the lever 6 is connected to the toggle switch 31 on the color temperature adjustment module 3.

[0035] In this utility model, the light-emitting unit 4 is detachably connected inside the profile body 1, and the end caps 5 on both sides stop and position the light-emitting unit 4, thereby improving the overall assembly convenience. At the same time, the color temperature adjustment module 3 is installed inside the insulating tube 2, which can be used to insulate and protect the color temperature adjustment module 3, thereby further improving the stability of the device.

[0036] In some embodiments, the profile body 1 of the present invention has openings at both ends;

[0037] An inner groove 11 and an outer groove 12 are provided at the upper end of the profile body 1.

[0038] Furthermore, in this embodiment, the light-emitting unit 4 includes a lamp board 41 and a lampshade 42, and the lamp board 41 is electrically connected to the color temperature adjustment module 3;

[0039] The lamp panel 41 is slidably connected in the inner groove 11, the lampshade 42 is slidably connected in the outer groove 12, and the end cap 5 is snapped onto the outer side of the ends of the lamp panel 41 and the lampshade 42.

[0040] Specifically, in this embodiment, both ends of the lower side of the lampshade 42 are formed with bent portions, which are slidably connected in the outer buckle groove 12. In addition, the arc-shaped structural component of the lampshade 42 has its arc surface protruding outward toward the side away from the lamp plate 41.

[0041] Furthermore, the lamp board 41 described in this utility model has a number of LED beads distributed at intervals, which adopt a 24-series-4-parallel double-row LED array, namely LED1-LED192. Among them, LED1-LED96 are 6500K cool white LED beads, and LED97-LED192 are 2700K warm white LED beads. The specific circuit connection diagram is shown in Figure 6.

[0042] Furthermore, in this embodiment, two toggle switches 31 are provided, and the two toggle switches 31 are respectively used to adjust the power and color temperature, such as... Figure 7 The diagram shown is a schematic of the driving circuit of one embodiment of the color temperature adjustment module 3. It uses a D1-D4 rectifier bridge to achieve 100-277V AC / DC conversion, C1-C3 to form a π-type filter network, and five power channels (5-way 5V) generated by a 5-position SW1 switch (one toggle switch 31) and resistors R12-R15. Six programmable drive signals are generated by a 6-position SW2 switch (another toggle switch 31), resistors R23-R34, and diodes D10-D14 to achieve adjustable six color temperatures. Those skilled in the art can reproduce the technical solution of this application based on this circuit diagram; therefore, further details are omitted here.

[0043] Based on the above embodiments, in this embodiment, the end face of the insulating tube 2 is provided with a clearance opening 21 for the toggle switch 31, and a groove 13 is provided on the outer side of the profile body 1 facing the clearance opening 21. The groove 13 is for the purpose of facilitating the installation of the toggle switch 6.

[0044] Specifically, in this embodiment, the inner side of the paddle 6 is formed with a sleeve 61 and two elastic arms 62, and the two elastic arms 62 are symmetrically designed.

[0045] The sleeve 61 enters along the slide groove 13 and the clearance opening 21 and is sleeved on the toggle block end of the toggle switch 31. The outer side of the elastic arm 62 is formed with a locking protrusion 63. The two elastic arms 62 pass through the slide groove 13, and the locking protrusion 63 stops on the inner side of the profile body 1.

[0046] Of course, in this utility model, the two elastic arms 62 are attached to the inner side of the slide groove 13 to ensure the stability of the slide. The design of two locking protrusions 63 on the inner side of the profile body 1 is used to prevent the paddle 6 from falling off.

[0047] In some embodiments, a socket 51 is embedded on the end face of the end cap 5 in this invention, and the socket 51 is electrically connected to the color temperature adjustment module 3.

[0048] Specifically, the socket 51 includes a positive terminal 52, a negative terminal 53, and a grounding terminal 54;

[0049] A grounding plate 55 is fixedly installed on the inner side of the end cap 5. One end of the grounding plate 55 is connected to the grounding post 54, and the other end is bent and abuts against the inner side of the profile body 1.

[0050] In this utility model, by using a design that embeds sockets 51 on sockets 51 at both ends, power can be connected at both ends during actual use, which improves the convenience of electrical connection of the entire lamp tube. In addition, by setting the grounding piece 55 as a bent structure, when the end cap 5 is installed, the grounding piece 55 fits against the outside of the profile body 1, which can ground the entire profile body 1. Once the profile body 1 becomes energized due to a circuit fault, the current will be quickly conducted to the ground through this grounding piece 55, instead of through the human body or other equipment, thereby avoiding the danger of electric shock and equipment damage, and achieving grounding protection.

[0051] In addition, the end cap 5 and the profile body 1 in this utility model are connected by fasteners, which are bolts, and a clearance hole is provided on the end face of the grounding plate 55 to avoid the bolt.

[0052] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
