Description

Technical Field

[0001] The present invention relates to a bracket, particularly a bracket having foolproof features. The present invention also relates to a lighting device having such a bracket.

Background Art

[0002] Replaceable lamp tubes are widely applied in commercial buildings, industrial buildings or residences because they are convenient to use. However, some lamp tubes cannot be attached to a lamp holder having an electronic ballast, and may not be able to be attached to a lamp holder having an inductive ballast with a preheating function either. If these lamp tubes are attached to the above lamp holders, the lamp tubes may be damaged or accidents such as fires may be caused. However, since conventional lamp tubes do not have an appropriate foolproof structure, users are likely to accidentally attach lamp tubes to incompatible lamp holders.

[0003] In addition, conventional lamp tubes are not provided with an appropriate safety structure, and the lamp tubes may fall due to an earthquake or the like. Therefore, it is also necessary to improve the safety and reliability of conventional lamps.

Each bracket includes a bracket body, two conductive plates, a rotating fixing member, and a mounting fixing member. The two conductive plates are mounted on the bracket body, which has an upper hole, a central column, and a central recess. The central column is mounted on the central recess. The rotating fixing member is rotatably connected to the central column and has an extended portion and two through holes mounted opposite each other. The rotating fixing member can rotatably align the two through holes and the upper hole. The rotating fixing member passes through the upper hole and the two through holes. The lamp tube is electrically connected to the two conductive plates and has a tube body and two end caps mounted on both ends of the tube body. The two end caps are mounted on the two brackets. Each end cap has an extended space, and the extended space of the end cap and the corresponding extended portion of the rotating fixing member interlock with each other.

[0006] A foolproof bracket is provided based on one embodiment of the present invention, comprising a bracket body, two conductive plates, a rotating fixing member, and a mounting fixing member. The bracket body has an upper hole, a central column, and a central recess. The central column is installed in the central recess. The two conductive plates are installed on the bracket body. The rotating fixing member is rotatably connected to the central column and has an extended portion and two through holes installed opposite each other. The rotating fixing member can rotatably align the two through holes and the upper hole. The mounting fixing member passes through the upper hole and the two through holes. [Effects of the Invention]

[0007] Based on the above, the bracket and lighting device having a foolproof structure according to the embodiment of the present invention may have one or more of the following advantages. (1) In one embodiment of the present invention, the lighting device includes two brackets, a lamp tube, and a mounting fixing member. Each bracket includes a bracket body, two conductive plates, a rotating fixing member, and a mounting fixing member. The two conductive plates are mounted on the bracket body, which has an upper hole, a central column, and a central recess. The central column is mounted on the central recess. The rotating fixing member is rotatably connected to the central column and has an extended portion and two through holes mounted opposite each other. The rotating fixing member can rotatably align the two through holes and the upper hole. The rotating fixing member passes through the upper hole and the two through holes. The lamp tube is electrically connected to the two conductive plates and has a tube body and two end caps mounted on both ends of the tube body. The two end caps are attached to the two brackets. The mounting fixing member passes through the upper hole and the two through holes. The structural design of the mounting fixing member requires tools to remove the lamp tube from the lighting device, significantly improving the safety and reliability of the lighting device. (2) In one embodiment of the present invention, the rotating fixing member of the lighting device has an extended portion. Each end cover has an extended space, and the extended space of the end cover interlocks with the extended portion of the rotating fixing member. The foolproof structure consisting of the extended space of the end cover and the extended portion of the rotating fixing member described above can effectively provide a foolproof function and allow only lamp tubes that fit the bracket to be attached.

(4) In one embodiment of the present invention, the rotating fixing portion of the bracket of the lighting device has an extended portion, and this extended portion has a special design that allows the extended space of the end cover to be firmly fitted with the extended portion of the rotating fixing member. The above structural design can further improve the structural stability of the lighting device. (5) In one embodiment of the present invention, the two conductive pins of each end cap of the lamp tube are installed on both sides of the extension space of the end cap. Therefore, when the user rotates the lamp tube, the extension portion of the rotation fixing member fitted into the extension space provides appropriate assistance and can share the force applied to the two conductive pins. Therefore, even when the user rotates the lamp tube, the conductive pins do not easily deform. (6) In one embodiment of the present invention, the structural design of the foolproof structure of the lighting device is simple, so the desired effect can be obtained without significantly increasing the cost. Therefore, the practicality of the lighting device is greatly improved, its range of applications is broadened, and it can meet the needs of actual applications. [Brief explanation of the drawing]

Figure 4 is a perspective view of the bracket of a lighting device having a foolproof structure according to the first embodiment of the present invention. Figure 5 is a perspective view of the rotating fixing member of a lighting device having a foolproof structure according to the first embodiment of the present invention. Figure 6 is an assembly view of the rotating fixing member and bracket of a lighting device having a foolproof structure according to the first embodiment of the present invention. As shown in the figures, the bracket 12 includes a bracket body 121, two conductive plates 122, a rotating fixing member 123, a fixing base 124, and a fixing member 125.

[0013] The central recess CR of the bracket body 121 has a central column 1211, and the upper part of the bracket body 121 has two upper holes TH.

[0014] The two conductive plates 122 and the fixing base 124 are installed on the bracket body 121, and the two conductive plates 122 are fixed on the fixing base 124. The two conductive plates 122 can be made of a metallic material such as copper, iron, aluminum, or a conductive alloy material.

[0015] The rotating fixing member 123 is installed in the central recess CR of the bracket body 121 and has two extension portions 1231, a central hole CH, and two positioning grooves PT. The central column 1211 of the bracket body 121 passes through the central hole CH of the rotating fixing member 123, rotatably connecting the rotating fixing member 123 to the central column 1211. The two positioning grooves PT correspond to the two upper holes TH, respectively, and are installed on both sides of one of the extension portions 1231. Therefore, the bracket 22 may have a double-channel design. In this embodiment, the extension portion 1231 may be a positioning plate. The extension portion 1231 is installed on the upper surface of the rotating fixing member 123 and extends upward in a tapered manner from the upper surface of the rotating fixing member 123. The upper end surface of the extension portion 1231 has an upper plane TP and two inclined upper surfaces TS, the upper plane TP is installed between the two inclined upper surfaces TS. In another embodiment, the extension portion 1231 may be a positioning block and may be a cylindrical, polygonal prism, or other different shape. In yet another embodiment, the extension portion 1231 may be a boss, projection, projection, bevel, snap structure, or any other structure having a similar function. The combined length of the two extension portions 1231 may be greater than half the length of the extension space 1321, and the two extension portions 1231 are designed to be symmetrical with respect to each other. The structure of the extension portions 1231 can be modified as needed and is not limited thereto.

[0016] Figures 7 and 8 are the first and second explanatory diagrams of the usage state of a lighting device having a foolproof structure according to the first embodiment of the present invention, and these are shown together with Figures 1 to 6. As shown in the figures, when a user wants to attach a lamp tube 13 to a bracket 12, the user aligns the two conductive pins 1322 of each end cap 132 of the lamp tube 13 with the two upper holes TH of the bracket body 121 of the corresponding bracket 12, and inserts the two conductive pins 1322 through the two upper holes TH into the positioning grooves PT of the rotating fixing member 123 of the bracket 12. At the same time, the two extended portions 1231 of the rotating fixing member 123 also fit into the extended spaces 1321 of the end cap 132. Next, the user rotates the lamp tube 13 at a preset angle (which may be clockwise or counterclockwise, in the direction indicated by the arrow AR in the figure) to bring the two conductive pins 1322 on each end cover 132 into contact with the two conductive plates 122 on the bracket body 121 of the corresponding bracket 12, thereby electrically connecting the lamp tube 13 to the conductive plates 122 of the bracket 12. Finally, the user can fix the fixing member 125 to one of the upper holes TH on the bracket body 121 to prevent the lamp tube 13 from falling out.

[0017] As can be seen from the disclosure of this embodiment, the foolproof structure consisting of the extended space 1321 of the end cover 132 and the extended portion 1231 of the rotating fixing member 123 effectively provides a foolproof function, making it possible to attach only the lamp tube 13 that fits the bracket 12. Therefore, the lighting device 1 will not be damaged by incorrect installation, and the service life of the lighting device 1 can be greatly extended. In addition, the end cover 132 and bracket 12 of the lighting device 1 have a special structural design, allowing the lamp tube 13 to be firmly fixed to the bracket 12. Therefore, the lighting device 1 achieves high structural stability and can effectively prevent the lamp tube 13 from falling off the bracket 12. Furthermore, the rotating fixing member 123 of the bracket 12 of the lighting device 1 has an extended portion 1231, and this extended portion 1231 has a special structural design, allowing the extended space 1321 of the end cover 132 to be firmly fitted with the extended space 1321 of the rotating fixing member 123. As described above, the two conductive pins 1322 of each end cap 132 of the lamp tube 13 are installed on both sides of the extension space 1321 of the end cap 132. Furthermore, the total length of the two extension portions 1231 may be greater than half the length of the extension space 1321, and the two extension portions 1231 are designed to be symmetrical to each other. Therefore, when the user rotates the lamp tube 13, the extension portions 1231 of the rotation fixing member 123 fitted into the extension space 1321 provide appropriate assistance and can share the force applied to the two conductive pins 1322. Consequently, the conductive pins 1322 are less likely to deform even when the user rotates the lamp tube 13.

[0018] The above structural design effectively prevents users from attaching the lamp tubes of conventional lighting devices to the brackets of emergency lighting devices, and also effectively prevents users from attaching the lamp tubes of emergency lighting devices to the brackets of conventional lighting devices. Therefore, the above structural design effectively improves the safety of the lighting devices and prevents damage to them.

The central column 2211 of the bracket body 221 passes through the central hole CH of the rotating fixing member 223, rotatably connecting the rotating fixing member 223 to the central column 2211. The two positioning grooves PT correspond to the upper hole TH and are installed opposite each other with the central hole CH as the center point, forming a single channel between the upper hole TH and the central hole CH. Therefore, the bracket 22 may have a single-channel design. In this embodiment, the extension portion 2231 may be a positioning plate.

Next, the user rotates the lamp tube 23 at a preset angle (which may be clockwise or counterclockwise, in the direction indicated by the arrow AR in the figure) to bring the two conductive pins 2322 on each end cover 232 into contact with the two conductive plates 222 on the bracket body 221 of the corresponding bracket 22, thereby electrically connecting the lamp tube 23 to the conductive plates 222 of the bracket 22. Finally, the user can fix the fixing member 225 to one of the upper holes TH on the bracket body 221 to prevent the lamp tube 23 from falling out.

[0026] Figures 17 and 18 are perspective and side views of an end cover of a lighting device having a foolproof structure according to a third embodiment of the present invention, with reference to Figure 1.

[0028] Similarly, the extended portion 3231 of the rotating fixing member 323 fits into the extended space 3321 of the end cover 332, effectively providing a foolproof function.

[0029] The structure of the extended portion and extended space in the above embodiment can be modified as needed, and the present invention is not limited thereto.

[0032] As shown in Figure 22, the rotating fixing member 423 has a central hole CH. The central column 4211 passes through the central hole CH, rotatably connecting the rotating fixing member 423 to the central column CH. The rotating fixing member 423 has two through holes VA that are installed opposite each other. The rotating fixing member 423 can rotatably align the two through holes VA with the upper hole TH. Since the central column 4211 has a central groove CG, the two through holes VA are aligned with the central groove CG and the upper hole TH.

In another embodiment, the extended space may be a recess formed by a hole or a slope. The extended space is disclosed in the second embodiment and will not be described in detail here. Similarly, each end cover 432 further has two conductive pins, which are inserted into corresponding rotating fixing members 423, bringing the two conductive pins into contact with the two conductive plates 422, respectively, and are positioned on opposite sides of the extension space (the structure of the two conductive pins is the same as in the second embodiment and will not be described or illustrated again here).

The rotating fixing member is rotatably connected to the central column and has an extended portion and two through holes mounted opposite each other. The rotating fixing member can rotatably align the two through holes and the upper hole. The rotating fixing member passes through the upper hole and the two through holes. The lamp tube is electrically connected to the two conductive plates and has a tube body and two end caps mounted on both ends of the tube body. The two end caps are attached to the two brackets. The mounting and fixing member passes through the upper hole and the two through holes. The structural design of the mounting and fixing member requires tools to remove the lamp tube from the lighting device, significantly improving the safety and reliability of the lighting device.

[0047] According to an embodiment of the present invention, the rotating fixing member of the lighting device has an extended portion. Each end cover has an extended space, and the extended space of the end cover interlocks with the extended portion of the rotating fixing member. The foolproof structure consisting of the extended space of the end cover and the extended portion of the rotating fixing member described above can effectively provide a foolproof function, allowing only lamp tubes that are compatible with the bracket to be attached. Therefore, the lighting device will not be damaged due to improper installation, and the service life of the lighting device can be greatly improved.

[0048] Furthermore, according to embodiments of the present invention, the end cover and bracket of the lighting device have a special structural design that allows the lamp tube to be firmly fixed to the bracket. Therefore, the lighting device achieves high structural stability and can effectively prevent the lamp tube from falling off the bracket. As can be seen from this, the service life of the lighting device can be further extended and the safety of the lighting device can be further improved.

[0049] Furthermore, according to an embodiment of the present invention, the rotating fixing portion of the bracket of the lighting device has an extended portion, and this extended portion has a special design that allows the extended space of the end cover to be firmly fitted with the extended portion of the rotating fixing member. The above-described structural design can further improve the structural stability of the lighting device.

[0050] Furthermore, according to an embodiment of the present invention, the two conductive pins of each end cap of the lamp tube are installed on both sides of the extension space of the end cap. Therefore, when the user rotates the lamp tube, the extension portion of the rotation fixing member fitted into the extension space provides appropriate assistance and can share the force applied to the two conductive pins. Consequently, even when the user rotates the lamp tube, the conductive pins do not easily deform.

[0051] Furthermore, according to embodiments of the present invention, the structural design of the foolproof structure of the lighting device is simple, so the desired effect can be obtained without significantly increasing costs. Therefore, the practicality of the lighting device is greatly improved, its range of applications is broadened, and it can meet the needs of actual applications.
