Description

Technical Field

[0001] The utility model relates to a lamp, in particular to a lamp with a light strip built into a lamp tube. Background Art

[0002] A conventional lamp comprises a glass outer tube, a plastic inner tube positioned within the outer tube, a carrier plate disposed within the inner tube, and two light strips mounted on opposite sides of the carrier plate. The lamp tube extends longitudinally and defines a central axis. The inner surface of the inner tube forms two opposing mounting rails for mounting the carrier plate. The carrier plate extends longitudinally and overlaps the central axis of the lamp tube.

[0003] However, the placement of the light strip near the central axis increases the optical distance from the light strip to the lamp tube, thereby reducing the intensity of the light exiting the lamp tube. Furthermore, the light from the light strip must pass through two layers of material, the inner and outer tubes, to reach the outside, further reducing the amount of light that can pass through the lamp tube. The luminous efficiency still needs improvement. Utility Model Content

[0004] The purpose of the present invention is to provide a lamp that can at least overcome the shortcomings of the prior art.

[0005] The present invention provides a lamp comprising a lamp tube and a light-emitting unit located within the lamp tube. The lamp tube extends along a length and defines a central axis. The lamp further comprises a bracket disposed within the lamp tube, the bracket comprising at least one mounting slot with an opening facing away from the central axis and extending along the length. The light-emitting unit is located between the lamp tube and the bracket and comprises at least one light bar mounted in the at least one mounting slot. The number of the at least one light bar is less than or equal to the number of the at least one mounting slot, and light emitted by the at least one light bar is directed toward the opening of the at least one mounting slot and projected onto the lamp tube.

[0006] The lamp of the present invention, the bracket includes a plurality of the mounting grooves, and a plurality of connecting parts adjacent to the inner wall surface of the lamp tube and connected to the mounting grooves, each of the mounting grooves has two protruding parts protruding from the connecting part toward the center axis, and a supporting part connected to the protruding parts and spaced from the lamp tube, the at least one light strip rests against the supporting part and is laterally limited by the protruding part.

[0007] In the lamp of the utility model, the cross section of the lamp tube is circular.

[0008] In the lamp of the utility model, the cross section of the lamp tube is in the shape of a rectangular ring.

[0009] The lamp of the present invention further comprises a clipping unit, which comprises a mounting frame and two clips connected to the mounting frame, and the clips are clipped on the periphery of the lamp tube.

[0010] In the lamp of the present invention, the clip unit further comprises two guide pieces extending from the clip in directions opposite to the mounting frame, and the spacing between the guide pieces expands in the direction opposite to the mounting frame.

[0011] The lamp of the utility model is made of transparent glass.

[0012] In the lamp of the utility model, the bracket unit is made of polycarbonate.

[0013] The lamp of the present invention further comprises two end covers arranged at both ends of the lamp tube.

[0014] The beneficial effect of the present invention is that the light emitted by the light bar is projected onto the lamp tube and is located close to the lamp tube. Compared with the prior art, the light emitted by the light bar only needs to penetrate the lamp tube to reach the outside, which can effectively increase the luminous efficiency of the lamp.

[0021] Before the present invention is described in detail, it should be noted that similar elements are represented by the same reference numerals in the following description.

[0022] See Figures 1 to 3The first embodiment of the lamp of the present invention comprises a lamp tube 1, a bracket 2, a light-emitting unit 3, a controller 4, a clip unit 5, and two end caps 6. The lamp can be used for indoor lighting, table lamps, advertising light boxes, etc.

[0023] The lamp tube 1 is made of transparent glass and extends along a length direction L1 and defines a central axis C1 . The cross section of the lamp tube 1 is circular.

[0024] The bracket 2 is made of polycarbonate and is disposed within the lamp tube 1. It includes four mounting slots 21 with openings facing away from the central axis C1 and extending along the longitudinal direction L1, and four connecting portions 22 adjacent to the inner wall of the lamp tube 1 and connected to the mounting slots 21. Each mounting slot 21 has two protruding portions 211 extending from the connecting portion 22 toward the central axis C1, and a supporting portion 212 connected to the protruding portions 211 and spaced apart from the lamp tube 1.

[0025] The light-emitting unit 3 is located between the lamp tube 1 and the bracket 2 and includes four light bars 31, each mounted in the mounting slot 21. Light emitted by each light bar 31 is directed toward the opening of the corresponding mounting slot 21 and onto the lamp tube 1. Each light bar 31 includes a circuit board 311, a plurality of light-emitting elements 312 mounted on the circuit board 311, and a plurality of encapsulation materials 313 covering the light-emitting elements 312. Each light bar 31 rests against the supporting portion 212 and is laterally restrained by the protruding portion 211.

[0026] The controller 4 is located in the bracket 2 and is electrically connected to the light bar 31 .

[0027] The clip unit 5 includes a mounting frame 51, two clips 52 connected to the mounting frame 51, two guides 53 extending from the clips 52 in a direction opposite to the mounting frame 51, and two cushioning materials 54 covering the clips 52 and the guides 53. The clips 52 are clipped onto the outer periphery of the lamp tube 1.

[0028] In the first embodiment, the number of the light bars 31 and the number of the mounting slots 21 are both four. However, in other embodiments, the number of the light bars 31 and the mounting slots 21 is not limited, and can be one light bar 31 and two mounting slots 21, or three light bars 31 and six mounting slots 21, as long as the number of the light bars 31 is less than or equal to the number of the mounting slots 21. Therefore, manufacturers can standardize the production specifications of the bracket 2, and users can use the same specification of lamps and install different numbers of light bars 31 according to actual conditions.

[0029] See Figure 4The second embodiment of the lamp of the present invention is different from the first embodiment in that the lamp tube 1 is in the shape of a square tube, and its cross section is in the shape of a rectangular ring.

[0030] See Figure 5 The third embodiment of the lamp of the present invention is different from the first embodiment in that the bracket 2 has six mounting slots 21, and three light strips 31 are respectively arranged in three adjacent mounting slots 21 to concentrate the direction of light irradiation. It can be used in situations where only one side of the light is required, such as for advertising light boxes.

[0031] In summary, since the light emitted by the light bar 31 of the lamp of the present invention is projected onto the lamp tube 1 and is located close to the lamp tube 1, the light emitted by the light bar 31 only needs to penetrate a layer of material of the lamp tube 1 to reach the outside compared to the prior art, which can effectively increase the luminous efficiency of the lamp, and thus can indeed achieve the purpose of the present invention.

[0032] The above description is merely a specific embodiment of the present invention and is not intended to limit the scope of the claims of the present invention. Equivalent variations based on the claims of the present invention and the contents of the specification should also be covered by the scope of the claims of the present invention.
