Detailed Implementation

[0016] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0017] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0018] Example 1 Reference Figures 1 to 3 Embodiment 1 provides a color temperature adjustable filament lamp tube (hereinafter referred to as filament lamp tube), including a tube body 1, a filament group, and a first electrical connection bracket 4, a second electrical connection bracket 5, and a third electrical connection bracket 6 fixedly connected to lamp holders 7 at both ends of the tube body 1. The first electrical connection bracket 4 is used to electrically connect to a first electrode (such as a positive electrode), and the second electrical connection bracket 5 and the third electrical connection bracket 6 are used to jointly electrically connect to a second electrode opposite to the first electrode (such as a negative electrode), and the first electrical connection bracket 4 is located between the second electrical connection bracket 5 and the third electrical connection bracket 6.

[0019] like Figure 2 and Figure 3As shown, the filament assembly of this embodiment includes multiple first filament units 2 and second filament units 3 arranged at intervals along the axial direction (i.e., left and right directions) of the tube body 1. The first filament unit 2 includes a white light filament 21, and the second filament unit 3 includes a warm light filament 31. Each first filament unit 2 and the second filament unit 3 that cooperate with it are arranged at relative intervals along the radial direction of the tube body 1. Furthermore, a white light filament 21 and a warm light filament 31 that are adjacent in the radial direction of the tube body 1 belong to the same group. In this way, by cooperating with each group of white light filaments 21 and warm light filaments 31, light of different color temperatures can be emitted.

[0020] In this embodiment, the first electrical connection bracket 4 has a plurality of broken line segments 41 arranged at axial intervals along the tube body 1 and a connecting segment 42 connecting two adjacent broken line segments 41. The extension direction of each broken line segment 41 is inclined to cross the axial direction of the tube body 1, and the extension directions of each broken line segment 41 are parallel to each other.

[0021] The second electrical connection bracket 5 and the third electrical connection bracket 6 are respectively linear structures 51 corresponding to the filament group, for electrically connecting the negative terminals of each filament.

[0022] During assembly, the first ends of the white light filament 21 and the warm light filament 31 of each group are electrically connected to the straight structure 51 of the second electrical connection bracket 5 and the third electrical connection bracket 6, respectively. The second end of the white light filament 21 of each group away from the second electrical connection bracket 5 and the second end of the warm light filament 31 of the same group away from the third electrical connection bracket 6 are electrically connected to two adjacent connecting segments 42 on the first electrical connection bracket 4, respectively. Different groups of white light filament 21 and warm light filament 31 that are adjacent to each other are all electrically connected to the same broken line segment 41 of the first electrical connection bracket 4. At this time, the long directions of the white light filament 21 and the warm light filament 31 of the same group are parallel to each other, and they are all installed obliquely inside the tube 1.

[0023] In summary, the first electrical connection bracket 4 is used to electrically connect the positive electrode, and the second electrical connection bracket 5 and the third electrical connection bracket 6 are used to jointly electrically connect the negative electrode. One end of each of the multiple first filament units 2 and the second filament units 3 is jointly electrically connected to the first electrical connection bracket 4, and the other ends of the multiple first filament units 2 and the second filament units 3 are respectively electrically connected to the second electrical connection bracket 5 and the third electrical connection bracket 6. At the same time, each first filament unit 2 and the corresponding second filament unit 3 are arranged in a relatively spaced manner in the radial direction of the tube body 1. In this way, light of different color temperatures can be emitted, thereby ensuring that the filament tube has an adjustable color temperature function, which can meet the usage needs of different application scenarios.

[0024] Of course, in other embodiments, the first filament unit 2 may also include a plurality of white light filaments 21, the connection method of which is similar to that in this embodiment; and / or, the second filament unit 3 may also include a plurality of warm light filaments 31, the connection method of which is similar to that in this embodiment.

[0025] Further preferred, such as Figure 2 and Figure 3 As shown, three of the connecting segments 42 of the first electrical connection bracket 4 are arched connecting segments 42', and the other connecting segments 42 of the first electrical connection bracket 4 are straight connecting segments 42''. The three arched connecting segments 42' are located at the beginning, middle, and end of the tube body 1, respectively, and abut against the inner wall of the tube body 1. This allows the filament assembly to be stably supported on the center line of the tube body 1. Of course, in other embodiments, the number of arched connecting segments 42' can also be four or more.

[0026] Further preferred, such as Figure 2 and Figure 3 As shown, multiple first filament units 2 are arranged at equal intervals along the axial direction of the tube body 1, and multiple second filament units 3 are arranged at equal intervals along the axial direction of the tube body 1, thus ensuring that the brightness of the entire illumination area of ​​the tube body 1 is uniform and consistent.

[0027] Example 2 Reference Figure 4 and Figure 5 Embodiment 2 provides a filament tube with adjustable color temperature. The structure of Embodiment 2 is generally the same as that of Embodiment 1, except that: the first filament unit 2' includes a first white light filament 22 and a first warm light filament 23, and the second filament unit 3' includes a second white light filament 32 and a second warm light filament 33, and the first filament unit 2' and the second filament unit 3' that are adjacent in the radial direction of the tube body 1 are in the same group.

[0028] The first electrical connection bracket 4' has a first straight segment 43 connected to the first and last ends of the tube body 1 and a plurality of horizontal segments 44 connected to the first straight segment 43 and arranged at equal intervals along the axial direction of the tube body 1. At this time, the extension direction of the first straight segment 43 is parallel to the axial direction of the tube body 1, and the first straight segment 43 and the horizontal segments 44 are perpendicular to each other and intersect each other.

[0029] The second electrical connection bracket 5' and the third electrical connection bracket 6' each have a second straight segment 52 connected to the first and last ends of the pipe body 1, and a plurality of arched segments 53 connected to the second straight segment 52 and arranged at equal intervals along the axial direction of the pipe body 1. At this time, the extension direction of the second straight segment 52 is parallel to the axial direction of the pipe body 1, and the plane where the arched segment 53 is located is perpendicular to the axial direction of the pipe body 1.

[0030] During assembly, the first ends of the first white light filament 22, the first warm light filament 23, the second white light filament 32, and the second warm light filament 33 in each group are electrically connected to the same horizontal segment 44 of the first electrical connection bracket 4'. The second ends of the first white light filament 22 and the second white light filament 32 in the same group, away from the horizontal segment 44, are electrically connected to the arched segment 53 of the second electrical connection bracket 5'. The second ends of the first warm light filament 23 and the second warm light filament 33 in the same group, away from the horizontal segment 44, are electrically connected to the arched segment 53 of the third electrical connection bracket 6'. That is, the first white light filament 22, the first warm light filament 23, the second white light filament 32, and the second warm light filament 33 in the same group are arranged in a straight line along the radial direction of the tube body 1, and the longitudinal direction of each filament is parallel to the axial direction of the tube body 1.

[0031] In this embodiment, the arched section 53 of the second electrical connection bracket 5' and the arched section 53 of the third electrical connection bracket 6' in the same group are in the same axial position on the tube body 1. The arched section 53 of the second electrical connection bracket 5' and the arched section 53 of the third electrical connection bracket 6' in the same group are located on the upper and lower opposite sides of the first electrical connection bracket 4', respectively. Therefore, the arched section 53 of the second electrical connection bracket 5' and the arched section 53 of the third electrical connection bracket 6' cooperate to stably support the filament assembly on the center line of the tube body 1.

[0032] By optimizing the installation structure of the first filament unit 2', the second filament unit 3', and each electrical connection bracket on the tube body 1, light of different color temperatures can be emitted, thereby ensuring that the filament tube has an adjustable color temperature function, which can meet the usage needs of different application scenarios.

[0033] Although the invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art will understand that various changes in form and detail may be made to the invention without departing from the spirit and scope of the invention as defined in the appended claims, all of which shall be within the scope of protection of the invention.
