[0047] To solve the problem in the prior art that LED lamps cannot be applied to multiple lighting occasions, the present disclosure provides an LED tube. The LED tube specifically includes a base 1, a light-transmitting lamp housing 4, an angle adjustment device 3, and at least two LED lamp boards 2.

[0048] Among them, at least two LED lamp boards 2 are arranged on the base 1 and are configured to mount LED lamps; the angle adjustment device 3 is installed on the base 1 and is configured to adjust the tilt angle of at least two LED lamp boards 2 relative to the base 1; the light-transmitting lamp housing 4 is connected to the base 1 to encapsulate at least two LED lamp boards 2.

[0049] In practical applications, such as Figure 1 , Figure 2As shown, the base 1 serves as the main carrier of the LED tube. One side of it is cooperatively installed with the light-transmitting lamp housing 4, and the internal cavity formed by the base 1 and the light-transmitting lamp housing 4 is used to install the LED lamp board 2. Different hanging parts can be set on the other side of the base 1 to fix the LED tube in different environments.

[0050] The LED lamp board 2 is provided with multiple rows of LED lamps. After being powered on, the light of the LED lamps passes through the light-transmitting lamp housing 4 to achieve lighting of the surrounding environment. At the same time, in order to adjust the lighting angle of the LED lamps and take into account the lighting range of the LED lamps, the LED tube provided by the present disclosure includes at least two LED lamp boards 2. Under the action of the angle adjustment device 3, the LED lamp board 2 can adjust the inclination angle of the LED lamp board 2 relative to the base 1 according to user needs.

[0051] More specifically, the above-mentioned inclination angle, in Figure 3 the case shown, essentially refers to the included angle a between the LED lamp board 2 and the surface of the base 1 in the radial cross-section of the LED tube. This included angle a can be adjusted. The smaller the included angle a is, the more concentrated the lighting area of the LED tube is. Correspondingly, the light in the lighting area is stronger.

[0052] For the LED tube provided by the present disclosure, by adjusting the inclination angle of the LED lamp board 2 relative to the base 1 through the angle adjustment device 3, the adjustment of the lighting area of the LED tube is achieved.

[0053] At the same time, in practical applications, an attribute adjustment knob for the LED lamps can also be set on the LED tube to adjust the light intensity and color temperature of the LED lamps themselves. By comprehensively controlling the self-attributes of the LED lamps and the lighting area of the LED lamps, the adjustment range of the lighting range and the irradiation light intensity of the LED tube is more comprehensive, so as to adapt to the usage requirements in various environments.

[0054] In an embodiment of the present disclosure, the angle adjustment device 3 includes a movable guide plate 31, a guide rod 32, and an adjustment bolt 33. Among them, the movable guide plate 31 is movably arranged on the base 1 and is provided with a guide groove 311; one end of the guide rod 32 is hinged to at least two LED lamp boards 2, and the other end is located in the guide groove 311; one end of the adjustment bolt 33 passes through the light-transmitting lamp housing 4 and is connected to the movable guide plate 31, and is configured to drive the movable guide plate 31 to move along the length direction of the LED lamp board 2 under the push of an external force, driving the guide rod 32 to move along the guide groove 311 to adjust the inclination angle of at least two LED lamp boards 2 relative to the base 1.

[0055] As Figure 5As shown, in actual use, the user can control the insertion amount of the adjusting bolt 33 into the transparent lamp housing 4 by rotating the adjusting bolt 33. Since one end of the adjusting bolt 33 is connected to the movable guide plate 31, when the user adjusts the insertion amount of the adjusting bolt 33 into the transparent lamp housing 4, the movable guide plate 31 will be pulled to move relative to the base 1.

[0056] A guide groove 311 is provided on the movable guide plate 31. One end of the guide rod 32 is hinged to at least two LED lamp boards 2, and the other end is located in the guide groove 311. When the movable guide plate 31 moves relative to the base 1, since the guide rod 32 is hinged to the LED lamp board 2 and the LED lamp board 2 is stationary relative to the base 1 in the length direction of the LED lamp board 2, the guide rod 32 will not move along the length direction of the LED lamp board 2. Instead, under the action of the guide groove 311 of the movable guide plate 31, it will reciprocate along the height direction of the LED lamp board 2, so that the height of the hinge joint between the LED lamp board 2 and the guide rod 32 increases or decreases, ultimately achieving the effect of adjusting the tilt angle of at least two LED lamp boards 2 relative to the base 1.

[0057] It should be noted that the length direction of the above-mentioned LED lamp board 2 refers to Figure 5 the x-axis direction shown in Figure 5 and the height direction of the LED lamp board 2 is

[0058] The LED lamp tube provided by the present disclosure drives the guide rod 32 to move by providing a guide groove 311 on the movable guide plate 31, thereby realizing the adjustment of the tilt angle of the LED lamp board 2 relative to the base 1. This angle adjustment device 3 has a simple and stable structure and is convenient for users to operate. It can reasonably adjust the lighting area of the LED lamp tube according to actual needs.

[0059] In an embodiment of the present disclosure, the guide groove 311 is a smooth curve groove extending along the length direction of the LED lamp board 2 and having an upper limit position and a lower limit position in the height of the LED lamp board 2.

[0060] As Figure 5 shown, in order to convert the movement of the adjusting bolt 33 and the movable guide plate 31 along the length direction of the LED lamp board 2 into the movement of the guide rod 32 along the height direction of the LED lamp board 2, thereby realizing the adjustment of the tilt angle of the LED lamp board 2 relative to the base 1. The LED lamp tube provided by the present disclosure enables the guide rod 32 to reciprocate along the height of the LED lamp board 2 by providing a smooth curve groove with an upper limit position and a lower limit position on the movable guide plate 31.

[0061] Specifically, in Figure 2In the case, when the guide rod 32 is at the upper limit position, at this time, the hinge joint of the two LED light boards 2 is at the highest position, and the inclination angle of the LED light board 2 relative to the base 1 is the largest. When the guide rod 32 is at the lower limit position, the LED light board 2 fits on the surface of the base 1.

[0062] The LED lamp tube provided by the present disclosure realizes the reciprocating movement of the guide rod 32 along the height of the LED light board 2 by arranging a smooth curve groove with an upper limit position and a lower limit position on the movable guide plate 31, thereby realizing the adjustment of the inclination angle of the LED light board 2 relative to the base 1.

[0063] In an embodiment of the present disclosure, a roller is provided at one end of the guide rod 32 located in the guide groove 311 of the movable guide plate 31.

[0064] Specifically, during the upward movement of the guide rod 32 along the height of the LED light board 2, the roller at the end of the guide rod 32 fits on the lower surface of the guide groove 311, and the roller is pushed by the lower surface of the guide groove 311 to push the guide rod 32 upward.

[0065] During the downward movement of the guide rod 32 along the height of the LED light board 2, the roller at the end of the guide rod 32 fits on the upper surface of the guide groove 311, and the roller is pulled by the upper surface of the guide groove 311 to pull the guide rod 32 downward.

[0066] The roller provided at the end of the guide rod 32 can effectively reduce the wear between the guide rod 32 and the guide groove 311. At the same time, the setting of the roller can make the adjustment of the inclination angle of the LED light board 2 relative to the base 1 smoother, improving the user experience.

[0067] In an embodiment of the present disclosure, the light-transmitting lamp housing 4 includes a light-transmitting lamp cover 41 and end caps 42. The light-transmitting lamp cover 41 is arranged to extend along the length direction of the LED light board 2 and cover at least two LED light boards 2. The end caps 42 are arranged at both ends of the light-transmitting lamp cover 41 and fixed to the base 1 to limit the movement of the light-transmitting lamp cover 41 along the length direction of the LED light board 2.

[0068] Specifically as Figure 2 shown, the light-transmitting lamp housing 4 includes a light-transmitting lamp cover 41 and end caps 42. The light-transmitting lamp cover 41 is arranged directly above the LED light board 2, and the light emitted by the LED lights on the LED light board 2 passes through the light-transmitting lamp cover 41 to illuminate the surrounding environment.

[0069] Convex platforms are provided on both sides of the light-transmitting lamp cover 41, and grooves are provided on both sides of the base 1. During the installation process, the convex platforms on both sides of the light-transmitting lamp cover 41 are inserted into the grooves on both sides of the base 1 to realize the connection between the light-transmitting lamp cover 41 and the base 1.

[0070] Subsequently, end caps 42 provided at both ends of the transparent lamp cover 41 are fixed to both ends of the base 1. Specifically, bolts can be used to fix the end caps 42 to the base 1, restricting the transparent lamp cover 41 from moving along the length direction of the LED lamp board 2, thereby realizing the fixation of the transparent lamp cover 41 relative to the base 1.

[0071] The LED lamp tube provided by the present disclosure realizes the fixation of the transparent lamp cover 41 relative to the base 1 through the end cap 42, ensuring the connection stability of the transparent lamp cover 41 relative to the base 1.

[0072] In an embodiment of the present disclosure, one end of the adjusting bolt 33 passes through the end cap 42 and is connected to the movable guide plate 31.

[0073] As Figure 5 shown, the end cap 42 is provided with a threaded hole, and the adjusting bolt 33 is engaged with the threaded hole, and is screwed into or out of the LED lamp tube after being stressed. One end of the adjusting bolt 33 is connected to the movable guide plate 31 in a movable manner, so that during the process of the adjusting bolt 33 being screwed into or out of the LED lamp tube, the movable guide plate 31 is pulled to move along the length direction of the LED lamp board 2.

[0074] Specifically, as Figure 6 shown, the movable guide plate 31 is provided with a first circular groove 312 and a second circular groove 313, wherein the diameter of the first circular groove 312 is larger than that of the second circular groove 313. During the installation process, first, the adjusting bolt 33 is screwed into the end cap 42, and then the end of the adjusting bolt 33 provided with a boss is placed into the first circular groove 312 of a movable guide plate 31, and then the boss at the end of the adjusting bolt 33 is enclosed by another movable guide plate 31, thereby realizing the movable connection between the adjusting bolt 33 and the movable guide plate 31.

[0075] Through the above method, it can not only realize the non-interference of the rotation of the adjusting bolt 33 itself, but also ensure that the adjusting bolt 33 guides the movement of the movable guide plate 31, thereby realizing the adjustment of the inclination angle of the LED lamp board 2 relative to the base 1.

[0076] In the actual application process, considering the problem that the material of the end cap 42 is prone to wear, a screw sleeve should also be installed at the position where the threaded hole is opened on the end cap 42, so that the screw sleeve is fixed relative to the end cap 42. The screw sleeve is in contact and cooperation with the adjusting bolt 33, realizing the screwing into or out of the adjusting bolt 33 from the LED lamp tube.

[0077] In an embodiment of the present disclosure, at least two LED lamp boards 2 are magnetically connected to the base 1 through magnetic members 21, and the angle adjusting device 3 overcomes the magnetic attraction force of the magnetic members 21 to adjust the inclination angle of at least two LED lamp boards 2 relative to the base 1.

[0078] As Figure 3As shown in the figure, a magnetic member 21 is provided on the surface of the LED lamp board 2 that contacts the base 1. The magnetic member 21 is fixed to the LED lamp board 2 and is attached to the base 1 by magnetic force. When the angle adjustment device 3 adjusts the tilt angle of the LED lamp board 2 relative to the base 1, the guide rod 32 pushes the LED lamp board 2 to move, causing one side of the LED lamp board 2 to overcome the magnetic attraction force and move away from the surface of the base 1. On the other side of the LED lamp board 2, due to the magnetic attraction force, during the movement of the LED lamp board 2, the other side of the LED lamp board 2 will move along the surface of the base 1 and towards the center line of the two LED lamp boards 2, and the edge line of the other side of the LED lamp board 2 always remains in contact with the surface of the base 1.

[0079] The LED lamp tube provided by the present disclosure is provided with a magnetic attraction member on the LED lamp board 2, so that while the LED lamp board 2 adjusts the tilt angle relative to the base 1, the other side of the LED lamp board 2 always remains in contact with the surface of the base 1, which is convenient for users to control the tilt angle.

[0080] In an embodiment of the present disclosure, the end face of the light-transmitting lamp cover 41 is a wide-angle light homogenizing lens. In order to make the light emitted by the LED lamp tube more uniform, the LED lamp tube provided by the present disclosure adopts a light-transmitting lamp cover 41 with a wide-angle light homogenizing lens end face to avoid the LED lamp tube generating glare, which may cause harm to the user's eyes.

[0081] In an embodiment of the present disclosure, the light-transmitting lamp cover 41 is divided into an inner layer and an outer layer, and a sealed cavity is formed between the inner layer and the outer layer.

[0082] As Figure 2 shown, the light-transmitting lamp cover 41 is configured as a double-layer structure, and both the outer layer and the inner layer are configured as arched structures. During the lighting process of the LED lamp tube, the light beam emitted by the LED lamp undergoes two refractions through the inner layer and the outer layer, making the lighting range wider.

[0083] At the same time, in an embodiment of the present disclosure, the sealed cavity is filled with an inert gas. Specifically, the inert gas can be nitrogen, which changes the refractive index of the light by changing the medium through which the light of the LED lamp travels, thereby increasing the lighting range of the LED lamp tube.

[0084] The above has described the embodiments of the present disclosure. The above description is exemplary and not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes are obvious to those of ordinary skill in the art in the technical field without departing from the scope and spirit of the described embodiments. The selection of the terms used herein is intended to best explain the principles of the embodiments, practical applications, or improvements to the technology in the market, or to enable other ordinary skilled persons in the technical field to understand the disclosed embodiments. The scope of the present disclosure is defined by the appended claims.
