Description

Technical Field

[0001] The utility model relates to a lighting device, in particular to a tubular lamp. Background Art

[0002] Tubular lamps, such as fluorescent lamps, have a light panel installed inside. The light panel emits light from the front, but the light output from the back is poor. Therefore, when installing the tubular lamp, the light output position needs to be adjusted to ensure the light output effect. However, when the tubular lamp is not powered on, it is difficult to directly observe the position of the internal light panel, which increases the difficulty of installing the tubular lamp. The light output angle cannot be adjusted during use, and the flexibility of use is poor. Utility Model Content

[0003] The purpose of the present utility model is to provide a tubular lamp to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The solution of the utility model to solve its technical problems is:

[0005] A tubular lamp comprises: a lamp tube, in which a photoelectric power supply component is arranged; a rotating component, comprising a lamp head and a bracket, wherein the lamp head is sleeved on the end of the lamp tube, and a connecting ring is provided at the end of the lamp head away from the lamp tube, and the connecting ring is inserted into the bracket, and a positioning groove is provided on the outside of the connecting ring, and a plurality of positioning grooves are arranged around the center of the connecting ring, and a positioning block is provided in the bracket, and the positioning block can be fitted and connected in any one of the positioning grooves under the action of elastic force, and the rotating components are respectively provided at both ends of the lamp head, and any one of the lamp heads is electrically connected to the photoelectric power supply component.

[0006] This technical solution has at least the following beneficial effects: when installing the entire tubular lamp, the connecting rings at both ends of the lamp tube can be directly inserted into the two brackets, and then the two brackets can be respectively installed on the structural surface of the external device, such as a wall, to fix the entire installation. At this time, the positioning grooves on the outside of the connecting rings cooperate with the positioning blocks in the brackets to limit the relative rotation between the lamp tube and the brackets. When the lamp tube needs to be rotated to adjust its light output direction, direct force is applied to the lamp tube to overcome the elastic force of the positioning blocks in the brackets, so that the positioning blocks move out of the positioning grooves, thereby realizing the rotation adjustment of the lamp tube. When the lamp tube is rotated and adjusted to the required direction, After determining the light emitting direction, the positioning block on the bracket is matched and connected to the positioning slot at the location. The positioning block maintains the state of mutual cooperation with the positioning slot under the action of elastic force, thereby maintaining the position state of the lamp tube during normal operation, and connecting the power cord of the peripheral device to the lamp holder. In the working state, the lamp tube can also be rotated to adjust its light emitting direction according to the needs of use. Therefore, the utility model can save the step of judging the light emitting direction during installation, and can be adjusted after the installation is completed, which greatly improves the overall installation efficiency. In addition, the light emitting direction of the lamp tube can also be adjusted during use, and the overall use is more convenient and flexible.

[0007] As a further improvement to the above technical solution, a hole is provided on one side of the bracket, an elastic sheet is connected to a position of the bracket on one side of the hole, and the positioning block is formed on the elastic sheet. The elastic sheet has only one side connected to the side edge of the hole of the bracket. When the positioning block applies pressure to the elastic sheet, the elastic sheet elastically deforms at the hole position away from the lamp holder, thereby allowing the positioning block to escape from the positioning slot. When the positioning block moves to an adjacent positioning slot, the elastic return of the elastic sheet provides an elastic force pressing the positioning block toward the positioning slot, causing the positioning block to re-engage in the adjacent positioning slot.

[0008] As a further improvement to the above technical solution, the outer side of the connecting ring is raised toward the center thereof to form an avoidance groove, a notch is provided on the outer side of the end of the connecting ring close to the lamp holder, the notch extends around the connecting ring and passes through the avoidance groove, and the positioning block is provided with an anti-slip protrusion extending into the notch at a position opposite to the notch, and the anti-slip protrusion can pass through the avoidance groove along the axial direction of the connecting ring. When the lamp holder is inserted into the bracket, the anti-slip protrusion in the bracket is aligned with the avoidance groove on the connecting ring, and then the bracket is inserted into the outer side of the connecting ring along the axial direction of the lamp holder. During this process, the anti-slip protrusion passes through the avoidance groove along the axial direction of the connecting ring and enters the notch, and then the bracket and the lamp holder are rotated relative to each other so that the anti-slip protrusion and the avoidance groove are staggered. At this time, when the bracket and the lamp holder are separated again, the anti-slip protrusion abuts against the position of the connecting ring close to the notch, which limits the bracket from slipping out of the lamp holder. In this way, the lamp holder and the bracket can be assembled quickly and stably with each other, especially when the lamp holder and the bracket are installed as a whole, it is not easy for the lamp holder and the bracket to separate from each other, thereby improving the convenience of installation.

[0009] As a further improvement to the above technical solution, a channel is provided in the bracket along the axial direction of the connecting ring, and a limiting rib is provided on the inner side of the channel. The limiting rib extends around the channel, and the connecting ring is inserted into one end of the channel and abuts against the limiting rib. During overall assembly, the lamp holder is inserted into the channel of the bracket and abuts against the limiting rib on the inner side of the channel. The limiting rib can be used to limit the travel of the lamp holder within the bracket, allowing for quick positioning of the lamp holder. When power is required, the power connector of an external device can be inserted from the other end of the channel to establish an electrical connection with the lamp holder.

[0010] As a further improvement to the above technical solution, the bracket is connected to an outer side of the end away from the lamp tube with fixing ribs, with at least two fixing ribs spaced apart, and a fixing hole is provided on the bracket between the two fixing ribs. During overall installation and fixation, the at least two fixing ribs form at least two support points. The fixing ribs are placed against the wall surface of the external device to better adapt to different wall shapes. Then, connecting parts of the external device, such as screws or bolts, are passed through the fixing holes and connected to the wall surface, and the bracket is pressed and fixed using the connecting parts.

[0011] As a further improvement of the above technical solution, the present invention further comprises a lampshade connected to the bracket, which can gather the light emitted outwards and improve the illumination intensity of the light.

[0012] As a further improvement to the above technical solution, a positioning post is connected to the outside of the bracket, a positioning hole is provided on the lampshade, the positioning post is inserted into the positioning hole, a positioning screw is passed through the lampshade, and the positioning screw is connected to the bracket. When installing and fixing the lampshade, the positioning post on the outside of the bracket cooperates with the positioning hole on the lampshade to quickly position the lampshade and the connecting tube, improving the convenience of lampshade installation. The positioning screw is then passed through the lampshade and connected to the lampshade, and the lampshade is pressed and fixed to the bracket to achieve a stable connection between the two.

[0013] As a further improvement to the above technical solution, a positioning recessed angle is formed between the end of the fixing rib and the outer side of the bracket, and the side edge of the lampshade is inserted into the positioning recessed angle. When installing the lampshade, the side edge of the lampshade can be placed close to the positioning recessed angle, improving the convenience of positioning the lampshade. The recessed angle of the fixing rib also creates a space for the head of the fixing screw to avoid damage, allowing the side edge of the fixing rib to be closely attached to the structural surface of the external device, thereby preventing damage to the structural surface.

[0014] As a further improvement to the above technical solution, the two fixing ribs gradually approach the lamp tube. The two fixing ribs are used to support the wall surface, and the two fixing ribs are tilted to increase the coverage area supported on the wall surface, thereby further improving the stability of the wall surface.

[0015] As a further improvement to the above technical solution, multiple positioning ribs are provided on the inner side of the connecting ring, and the spaces between these ribs form a plug retaining area. When the external power connector is electrically connected to the lamp holder, the multiple positioning ribs abut against the outer side of the power connector, securing and locking the power connector, effectively preventing the power connector from falling out of the lamp holder when pulled.

[0027] Reference Figure 1 and Figure 2 A tubular lamp includes a lamp tube 100 and a rotating assembly, wherein a light power supply assembly is provided inside the lamp tube 100, and the light power supply assembly includes a lamp board and a lamp body, the lamp board is connected to the lamp tube 100, and the lamp body is connected to the lamp board. The circuit board electrically connected to the lamp board can be placed outside the lamp board, for example, mounted on a lamp holder 210, or directly mounted on the circuit board. The lamp tube 100 is made of a translucent material, and the lamp body can emit light outward through the lamp tube 100 when working; the rotating assembly includes a lamp holder 210 and a bracket 220, the lamp holder 210 is sleeved on the end of the lamp tube 100, and the lamp holder 210 is away from the lamp tube 1 00 is provided with a connecting ring 211 at the end, and the connecting ring 211 is inserted into the bracket 220. A positioning groove 212 is provided on the outside of the connecting ring 211. There are multiple positioning grooves 212 arranged around the center of the connecting ring 211. A positioning block 221 is provided in the bracket 220, and the positioning block 221 can be connected to any one of the positioning grooves 212 under the action of elastic force. The rotating components are respectively provided at both ends of the lamp head 210, that is, the two lamp heads 210 are respectively mounted on the two ends of the lamp tube 100, and any one of the lamp heads 210 is electrically connected to the optical power supply component.

[0028] As can be seen from the above, when installing the entire tubular lamp, the connecting rings 211 at both ends of the lamp tube 100 can be directly inserted into the two brackets 220, and then the two brackets 220 can be respectively installed on the structural surface of the external device, such as a wall, to fix the entire installation. At this time, the positioning grooves 212 on the outside of the connecting rings 211 cooperate with the positioning blocks 221 in the brackets 220 to limit the relative rotation between the lamp tube 100 and the brackets 220. When the lamp tube 100 needs to be rotated to adjust its light output direction, direct force is applied to the lamp tube 100 to overcome the elastic force of the positioning blocks 221 in the brackets 220, so that the positioning blocks 221 move out of the positioning grooves 212, thereby realizing the rotation adjustment of the lamp tube 100. After rotating and adjusting to the required light output direction, the positioning block 221 on the bracket 220 is matched and connected to the positioning groove 212 at the location. The positioning block 221 maintains the state of mutual cooperation with the positioning groove 212 under the action of elastic force, thereby maintaining the position state of the lamp tube 100 during normal operation, and connects the power cord of the peripheral to the lamp head 210. In the working state, the lamp tube 100 can also be rotated to adjust its light output direction according to the needs of use. Therefore, the utility model can save the step of judging the light output direction during installation, and can be adjusted after the installation is completed, which greatly improves the overall installation efficiency. In addition, the light output direction of the lamp tube 100 can also be adjusted during use, and the overall use is more convenient and flexible.

[0029] like Figure 3 As shown, the positioning block 221 is pressed toward the positioning groove 212 under the action of elastic force. An elastic structure, such as a spring rod, may be provided in the bracket 220. The positioning block 221 is connected to the elastic movable end of the spring rod, and the spring rod presses the positioning block 221 toward the positioning groove 212. In order to simplify the structure and reduce production costs, in this embodiment, a hole is provided on one side of the bracket 220, and an elastic sheet 222 is connected to the position of the bracket 220 on one side of the hole. The positioning block 221 is formed on the elastic sheet 222. In actual application, the elastic sheet 222 and the bracket 220 are an integrally formed structure. Hollowing is provided on three sides of the bracket 220 around the elastic sheet 222, and only one side of the elastic sheet 222 is retained to remain connected to the bracket 220. The elastic sheet 222 has only one side connected to the side edge of the hole of the bracket 220. When the positioning block 221 transmits pressure to the elastic sheet 222, the elastic sheet 222 can be elastically deformed at the hole position in the direction away from the lamp holder 210, so that the positioning block 221 can fall out of the positioning groove 212. When the positioning block 221 moves to an adjacent positioning groove 212, the elastic reset of the elastic sheet 222 provides an elastic force to press the positioning block 221 toward the positioning groove 212, so that the positioning block 221 can be fitted into the adjacent positioning groove 212 again.

[0030] When the bracket 220 is inserted into the outer side of the connecting ring 211, the bracket 220 and the lamp holder 210 can be kept connected to each other only by the friction between the outer side of the connecting ring 211 and the inner side of the bracket 220. This assembly method has low stability and the bracket 220 is easy to loosen and separate from the lamp holder 210 during installation. In order to improve installation efficiency, Figure 4 As shown, in this embodiment, the outer side of the connecting ring 211 protrudes toward its center to form an avoidance groove 213, and a notch 214 is provided on the outer side of the end of the connecting ring 211 close to the lamp holder 210. The notch 214 extends around the connecting ring 211 and passes through the avoidance groove 213. The positioning block 221 is provided with an anti-slip protrusion 223 extending into the notch 214 at a position opposite to the notch 214. The anti-slip protrusion 223 can pass through the avoidance groove 213 along the axial direction of the connecting ring 211. In actual application, the coverage range of the positioning groove 212 set on the outer side of the connecting ring 211 is one half or three quarters, and multiple positioning grooves 212 are arranged on the outer side of the connecting ring 211 to form a positioning area. At this time, the avoidance groove 213 can be located in the middle position of the positioning area on the connecting ring 211, which is convenient for unifying the light output range of the lamp tube 100 in the initial state, and rotating the lamp tube 100 forward or reversely to adjust the light output when it is necessary to adjust the light output.

[0031] When the bracket 220 is separated from the lamp holder 210, the anti-slip protrusion 223 abuts against the position of the connecting ring 211 near the notch 214, which restricts the bracket 220 from slipping out of the lamp holder 210. In this way, the lamp holder 210 and the bracket 220 can be quickly and stably assembled with each other, especially when the lamp holder 210 and the bracket 220 are not easily separated from each other during the overall installation, thereby improving the convenience of installation.

[0032] The bracket 220 can be fixed relative to the outside of the connecting ring 211. In some embodiments, a channel is provided in the bracket 220 along the axial direction of the connecting ring 211. A limiting rib 224 is provided inside the channel. The limiting rib 224 extends around the channel, and the connecting ring 211 is inserted into one end of the channel and abuts against the limiting rib 224. During overall assembly, the lamp holder 210 is inserted into the channel of the bracket 220 and abuts against the limiting rib 224 inside the channel. The limiting rib 224 can limit the travel of the lamp holder 210 into the bracket 220, allowing for quick positioning of the lamp holder 210. When power is required, the power connector of an external device can be inserted from the other end of the channel to establish an electrical connection with the lamp holder 210.

[0033] When the bracket 220 is against a structural surface of an external device, such as a wall, the bracket 220 and the wall may be in surface contact. When the wall is uneven, the stability of the bracket 220 installation is easily affected. Therefore, in this embodiment, the bracket 220 is connected to the outer side of the end away from the lamp tube 100 with a fixing rib 225. At least two fixing ribs 225 are arranged at intervals, and a fixing hole 280 is provided on the bracket 220 between the two fixing ribs 225. When the overall installation is fixed, at least two fixing ribs 225 form at least two supporting fulcrums. When the fixing ribs 225 are pressed against the wall of the external device, it can better adapt to walls of different shapes. Then, the external device connectors, such as screws or bolts, are passed through the fixing holes 280 and connected to the wall. The bracket 220 is pressed and fixed by the connectors.

[0034] In actual applications, in order to facilitate the adjustment of the installation position of the bracket 220, the fixing hole 280 can be extended to the side of the bracket 220 away from the lamp tube 100. At this time, the fixing hole 280 is strip-shaped. When it is necessary to drive in screws or bolts and other connecting parts, the accuracy of opening the hole on the wall can be reduced, thereby improving the convenience of installation.

[0035] In order to improve the light effect, Figure 5 As shown, the present invention further includes a lampshade 300, which is connected to the bracket 220. The lampshade 300 can gather the light emitted outward, thereby improving the illumination intensity of the light. The lampshade 300 has various shapes, for example, including a back plate and side plates connected to both sides of the back plate, the back plate is set on the bracket 220, and the two side plates are gradually inclined in a direction away from each other. At this time, the entire lampshade 300 forms an opening that gradually opens outward, and the lamp tube 100 is located in the opening. The back plate and the two side plates gather and emit light, thereby improving the illumination brightness.

[0036] The lampshade 300 can be fixed to the bracket 220 by snapping, or connected to the bracket 220 by directly driving screws. In order to improve the convenience of mutual assembly, in this embodiment, a positioning column 260 is connected to the outside of the bracket 220, and a positioning hole is provided on the lampshade 300. The positioning column 260 is inserted into the positioning hole. The lampshade 300 is penetrated by a positioning screw, and the positioning screw is connected to the bracket 220. When installing and fixing the lampshade 300, the positioning column 260 on the outside of the bracket 220 and the positioning hole on the lampshade 300 can cooperate with each other to achieve rapid positioning of the lampshade 300 and improve the convenience of installing the lampshade 300. Then, the positioning screw is passed through the lampshade 300 and connected to the lampshade 300, and the lampshade 300 is pressed and fixed to the bracket 220 to achieve a stable connection between the two.

[0037] In actual application, the positioning column 260 can extend to the plane where the fixing ribs 225 are located away from the bracket 220. At this time, the positioning column 260 and the two fixing ribs 225 form a triangular support, which can improve the stability against the wall.

[0038] When screws are driven into the lampshade 300 to connect it to the bracket 220, in order to reduce the interference of the screw heads with the wall when the fixing ribs 225 abut against the wall, in this embodiment, a positioning recessed corner 270 is formed between the end of the fixing rib 225 and the outer side of the bracket 220, and the side of the lampshade 300 is inserted into the positioning recessed corner 270. When installing the lampshade 300, the side of the lampshade 300 can be placed close to the positioning recessed corner 270, which improves the convenience of positioning the lampshade 300. The recessed corner position of the fixing rib 225 also creates a space for the fixing screw heads to avoid, so that the side of the fixing rib 225 can be closely attached to the structural surface of the external device, avoiding damage to the structural surface.

[0039] The two fixing ribs 225 can extend in parallel directions. To enhance stability in contact with the wall, in this embodiment, the two fixing ribs 225 gradually approach the lamp tube 100. In actual use, the two fixing ribs 225 can also gradually move away from the lamp tube 100. The two fixing ribs 225 are used to support the wall, and the inclined design of the two fixing ribs 225 can increase the coverage area of ​​the support on the wall, thereby further improving stability against the wall.

[0040] The lamp holder 210, used for connecting to electricity, is connected to a power post, which is interconnected with the wires connected to the lamp panel. Once the external power connector is connected to the power post, it can be fixed to the bracket 220 solely by virtue of the connection with the power post. To improve the structural stability of the connection between the two, in this embodiment, a plurality of positioning ribs 215 are provided on the inner side of the connecting ring 211. The plurality of positioning ribs 215 are arranged between the plurality of positioning ribs 215 to form a plug retaining area. When the external power connector is electrically connected to the lamp holder 210, the plurality of positioning ribs 215 abut against the outer side of the power connector, limiting and tightening the power connector, effectively preventing the power connector from being easily dislodged from the lamp holder 210 when pulled. In actual use, the side of the plurality of positioning ribs 215 near the centerline of the lamp tube 100 is inclined, so that the plug retaining area formed by the surrounding area gradually increases in size as it moves away from the lamp tube 100. When the power connector is inserted, it can be guided by the plug retaining area to better align with the power post, improving installation efficiency.

[0041] The above specifically describes the preferred embodiments of the present invention, but the invention is not limited to the embodiments.
