Abstract
Description
Technical Field
[0001] This utility model relates to a lighting device, and more particularly to a rail light. Background Technology
[0002] Track lights, also known as rail lights, are widely used in commercial and residential lighting. Current track lights use a plastic housing with an internal ceramic lamp holder. The light source is mounted on the ceramic lamp holder to provide the overall illumination. In this type of track light, multiple connectors are needed within the housing to secure the ceramic lamp holder, lens, and light source. This requires a complex internal connection structure, resulting in complicated assembly and low production efficiency. Therefore, there is an urgent need for a track light with an optimized internal structure. Utility Model Content
[0003] The purpose of this utility model is to provide a rail light to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.
[0004] The solution to the technical problem of this utility model is:
[0005] A rail light includes: a bracket; a heat sink housing with a light outlet at one end and a mounting port at the other end, wherein an annular step is provided on the inner side of the end of the heat sink housing near the light outlet, and a positioning support is provided on the inner side of the end of the heat sink housing near the mounting port; a light source plate connected to the annular step; a lens connected to the heat sink housing and covering the light outlet; a control board abutting against the positioning support and electrically connected to the light source plate; and an end cap connected to the heat sink housing and covering the mounting port, wherein the end cap abuts against the side of the control board away from the positioning support, and the end cap is connected to the bracket.
[0006] This technical solution has at least the following beneficial effects: When assembling the track light, the light source board is inserted into the heat sink from the light outlet. The light source board is positioned using an annular step, thus fixing it inside the heat sink. Then, the lens is installed inside the heat sink, and the light outlet is blocked and closed by the lens, allowing the light source board to emit light through the lens. At the other end of the heat sink, the control board is abutted against the positioning support for initial positioning. Then, the end cap blocks and closes the mounting opening. The end cap presses against the side of the control board away from the positioning support, further securing the control board inside the heat sink. At the same time, the end cap and the bracket are connected to form a whole. The bracket is used to install and connect to the external structure, such as a pre-installed indoor track, thus achieving overall installation and fixation during use. In this way, when assembling the track light, the light source board and control board can be quickly inserted from both ends of the heat sink, reducing the use of connecting parts, simplifying the internal structure of the track light, and greatly improving the assembly efficiency of the track light.
[0007] As a further improvement to the above technical solution, the heat dissipation shell includes an outer cylinder and a heat dissipation tube connected to the outer cylinder. The two ends of the outer cylinder form the light outlet and the mounting port, respectively. The end of the heat dissipation tube forms the annular step, and the inner side of the outer cylinder forms the positioning support rib. During production, the outer cylinder and the heat dissipation tube can be made of different materials. The heat dissipation tube allows for rapid heat transfer from the light source board and control board. Since the light source board is mounted on the annular step formed at the end of the heat dissipation tube, the heat generated by the light source board can be directly conducted to the heat dissipation tube. This improves the heat dissipation efficiency of the light source board and control board. The outer cylinder serves to enclose and protect the internal structures, such as the heat dissipation tube. This improves overall heat dissipation efficiency while better controlling overall production costs.
[0008] As a further improvement to the above technical solution, the heat dissipation cylinder is made of metal, and the outer cylinder is made of plastic, with the outer cylinder and the heat dissipation cylinder being integrally formed. The metal heat dissipation cylinder can accelerate heat conduction, allowing heat to be evenly distributed in all directions, thus improving heat dissipation efficiency. The plastic outer cylinder is lightweight, has lower production costs, and better insulation properties. Heat conducted to the surface of the heat dissipation cylinder is then transferred outwards to the outer cylinder, where it is further dissipated, achieving efficient heat dissipation.
[0009] As a further improvement to the above technical solution, multiple connecting protrusions are formed on the outer side of the light source plate, and these connecting protrusions press against the inner side of the annular step. When the light source plate is installed into the annular step, the multiple connecting protrusions on the outer side of the light source plate press against the inner side of the annular step, which increases the pressure on the inner side of the annular step, making the light source plate more securely installed inside the annular step.
[0010] As a further improvement to the above technical solution, a connecting edge is provided on the outer side of the lens, and the connecting edge is connected to the inner side of the outer cylinder by a snap fastener. The connecting edge on the outer side of the lens can increase the contact area when it abuts against the inner side of the outer cylinder, thereby making the connection between the lens and the outer cylinder more tight. Furthermore, by using the snap fastener to connect the connecting edge to the inner side of the outer cylinder, the lens can be quickly connected and fixed, making it less likely for the lens to come off the outer cylinder after installation.
[0011] As a further improvement to the above technical solution, a positioning platform is provided on the inner side of the outer cylinder. A positioning post is formed on the positioning platform along the direction close to the mounting opening. A positioning hole is provided on the control plate, and the positioning post passes through the positioning hole. The control plate abuts against the positioning platform. When installing the control plate, the positioning hole on the control plate is aligned with the positioning post on the inner side of the outer cylinder. Through the mutual cooperation of the positioning post and the positioning hole, the control plate can be quickly positioned and installed, and the relative displacement of the control plate within the outer cylinder can be limited. When the control plate is fully installed, the positioning platform itself can provide support for the control plate, further improving the structural stability of the control plate when the end cap presses against it.
[0012] As a further improvement to the above technical solution, a positioning concave angle is provided on the side of the positioning support near the center of the outer cylinder, and a positioning groove is provided on one side of the control plate. The positioning support is inserted into the positioning groove, and the control plate abuts against the positioning concave angle. When the control plate is installed into the outer cylinder, the positioning groove on the control plate is aligned with the positioning support. The cooperation between the two restricts the position of the control plate. After the control plate is installed in place, it abuts against the positioning concave angle. The positioning concave angle formed on the positioning support supports the control plate and clamps the side of the positioning control plate, thus further improving the installation stability of the control plate.
[0013] As a further improvement to the above technical solution, multiple mounting protrusions are formed on the outer side of the end cap, and these mounting protrusions press against the inner side of the outer cylinder. When the end cap is installed into the outer cylinder, the pressure exerted on the inner side of the outer cylinder by the multiple mounting protrusions increases, making the connection structure between the end cap and the outer cylinder more stable.
[0014] As a further improvement to the above technical solution, a connecting sleeve is provided inside the outer cylinder, and a connecting screw is passed through the end cap, which is engaged with the connecting sleeve. After the end cap is installed in the outer cylinder, the connecting screw can be passed through the end cap and engaged with the connecting sleeve, thereby ensuring that the end cap is securely installed inside the outer cylinder and effectively preventing the end cap from detaching from the outer cylinder.
[0015] As a further improvement to the above technical solution, the bracket includes a slide rail and a rotating rod connected to the bottom side of the slide rail, with the end cap rotatably connected to the bottom end of the rotating rod. In use, the slide rail is connected to an external structure, such as a pre-installed indoor track. The relative angle between the heat sink and the bracket can be adjusted by rotating the end cap, thereby adjusting the orientation of the light outlet. This allows for convenient adjustment of the light emission direction and improves the flexibility of use. Attached Figure Description

[0025] Reference Figure 1 , Figure 2 and Figure 3 A track light includes a bracket, a heat sink 100, a light source board 200, a lens 300, a control board 400, and an end cap 500. One end of the heat sink 100 has a light outlet 110, and the other end has a mounting opening 120. An annular step 130 is provided on the inner side of the end of the heat sink 100 near the light outlet 110, and a positioning support rib 140 is provided on the inner side of the end of the heat sink 100 near the mounting opening 120. The light source board 200 is connected within the annular step 130 and is an integrated light source board with multiple LEDs mounted on its surface. The lens 300 is connected within the heat sink 100 and covers the light outlet 110. In practical applications, it can be customized according to different usage needs. Different types of lenses 300 can be selected, for example, various light distribution angles such as 24°, 36°, or 60° can be selected; the control board 400 abuts against the positioning support 140, and the control board 400 is electrically connected to the light source board 200; the end cover 500 is connected inside the heat sink 100, the end cover 500 covers the mounting port 120, the end cover 500 abuts against the side of the control board 400 away from the positioning support 140, and the end cover 500 is connected to the bracket. In practical applications, an adjustment key can be provided on the control board 400, and a knob or toggle switch can be installed on the end cover 500. The adjustment end of the adjustment key is engaged with the knob or toggle switch, so that the adjustment key can be controlled by the knob or toggle switch on the end cover 500.
[0026] As described above, when assembling the track light, the light source board 200 is inserted into the heat sink 100 through the light outlet 110. The annular step 130 is used to position the light source board 200, thus fixing it inside the heat sink 100. Then, the lens 300 is installed inside the heat sink 100, using the lens 300 to block and close the light outlet 110, allowing the light source board 200 to emit light through the lens 300. At the other end of the heat sink 100, the control board 400 is abutted against the positioning support rib 140 for initial positioning. Finally, the end cap 500 is used to block and close the mounting plate. The mounting port 120, through the end cap 500 pressing against the side of the control plate 400 away from the positioning support 140, further secures the control plate 400 inside the heat sink 100. At the same time, the end cap 500 is connected to the bracket to form a whole, and the bracket is used to install and connect to the external structure, such as the indoor pre-installed track, so as to realize the installation and fixation of the whole during use. In this way, when assembling the rail light, the light source board 200 and the control plate 400 can be quickly installed from both ends of the heat sink 100, reducing the use of connecting parts, simplifying the internal structure of the rail light, and greatly improving the assembly production efficiency of the rail light.
[0027] The heat dissipation shell 100 may use only one material. However, in order to better control production costs, in this embodiment, the heat dissipation shell 100 includes an outer cylinder 150 and a heat dissipation cylinder 160 connected inside the outer cylinder 150. The two ends of the outer cylinder 150 respectively form the light outlet 110 and the mounting port 120. The end of the heat dissipation cylinder 160 forms the annular step 130. The inner side of the outer cylinder 150 forms the positioning support rib 140. During production, the outer cylinder 150 and the heat dissipation cylinder 160 can be made of different materials. The heat dissipation cylinder 160 can quickly transfer heat from the light source board 200 and the control board 400. The light source board 200 is mounted on the annular step 130 formed by the end of the heat dissipation cylinder 160. The heat generated by the light source board 200 can be directly conducted to the heat dissipation cylinder 160. The heat dissipation cylinder 160 can improve the heat dissipation efficiency of the light source board 200 and the control board 400. The outer cylinder 150 is used to surround and protect the internal structure such as the heat dissipation cylinder 160. In this way, the overall heat dissipation efficiency can be improved while the overall production cost can be better controlled.
[0028] Furthermore, the heat dissipation cylinder 160 is made of metal, and the outer cylinder 150 is made of plastic. The outer cylinder 150 and the heat dissipation cylinder 160 are integrally formed. In practical applications, multiple positioning ribs 140 are arranged around the inner side of the outer cylinder 150. At this time, the control plate 400 abuts against one or more of the positioning ribs, and a connecting cylinder is formed between the multiple positioning ribs 140. The connecting cylinder is attached to the outer side of the heat dissipation cylinder 160 to provide support and fixation for the heat dissipation cylinder 160. The metal heat dissipation cylinder 160 can accelerate heat conduction, so that heat can be evenly distributed in all directions, improving heat dissipation efficiency. Then, the plastic outer cylinder 150 is lighter, has lower production costs, and has better insulation performance. The heat conducted to the surface of the heat dissipation cylinder 160 is then transferred to the outer cylinder 150, and further dissipated outward through the outer cylinder 150, achieving efficient heat dissipation.
[0029] In the above embodiment, when the light source plate 200 is installed into the annular step 130, the side of the light source plate 200 can be directly pressed against the inner side of the annular step 130 and fixed in the heat sink 160 by interference fit. To further increase the pressure exerted by the light source plate 200 on the heat sink 160, in this embodiment, multiple connecting protrusions 210 are formed on the outer side of the light source plate 200, and these protrusions 210 press against the inner side of the annular step 130. When the light source plate 200 is installed into the annular step 130, the multiple connecting protrusions 210 on the outer side of the light source plate 200 press against the inner side of the annular step 130, increasing the pressure and making the installation of the light source plate 200 within the annular step 130 more stable.
[0030] Similarly, the lens 300 can be directly fixed inside the outer cylinder 150 by interference fit between its outer side and the inner side of the outer cylinder 150. In practical applications, a connecting step can also be provided on the inner side of the outer cylinder 150. When the lens 300 is installed, the connecting step is used for limiting the position, so that the lens 300 can be installed in the outer cylinder 150 more quickly. In order to further improve the stability of the connection between the lens 300 and the outer cylinder 150, in this embodiment, a connecting edge 310 is provided on the outer side of the lens 300. The connecting edge 310 is connected to the inner side of the outer cylinder 150 by a snap fastener. For example, a hook is provided on the connecting edge 310, and a slot is provided on the inner side of the outer cylinder 150. By using the cooperation of the hook and the slot, the lens 300 can be quickly installed inside the outer cylinder 150. The connecting edge 310 on the outer side of the lens 300 can increase the contact area when it abuts against the inner side of the outer cylinder 150, thereby making the connection between the lens 300 and the outer cylinder 150 tighter. Furthermore, by using the connecting edge 310 to snap onto the inner side of the outer cylinder 150, the lens 300 can be quickly connected and fixed, making it less likely for the lens 300 to come off the outer cylinder 150 after installation.
[0031] To better define the position of the control plate 400, in this embodiment, a positioning platform 170 is provided on the inner side of the outer cylinder 150. A positioning post is formed on the positioning platform 170 along the direction close to the mounting opening 120. A positioning hole 410 is provided on the control plate 400, through which the positioning post passes. The control plate 400 abuts against the positioning platform 170. When installing the control plate 400, the positioning hole 410 on the control plate 400 is aligned with the positioning post on the inner side of the outer cylinder 150. Through the cooperation of the positioning post and the positioning hole 410, the control plate 400 can be quickly positioned and installed, and the relative displacement of the control plate 400 within the outer cylinder 150 can be limited. After the control plate 400 is fully installed, the positioning platform 170 itself can provide support for the control plate 400, further improving the structural stability of the control plate 400 when the end cap 500 presses against it.
[0032] Furthermore, the positioning support rib 140 is provided with a positioning concave angle 141 on the side near the center of the outer cylinder 150, and a positioning groove 420 is provided on one side of the control plate 400. The positioning support rib 140 is inserted into the positioning groove 420, and the control plate 400 abuts against the positioning concave angle 141. In practical applications, there are multiple positioning support ribs 140, and the positioning concave angle 141 can be formed on multiple positioning support ribs 140, thereby limiting the position of the control plate 400. When the control plate 400 is installed into the outer cylinder 150, the positioning groove 420 on the control plate 400 is aligned with the positioning support rib 140. The cooperation between the two can restrict the position of the control plate 400. After the control plate 400 is installed in place, the control plate 400 abuts against the positioning concave corner 141. The positioning concave corner 141 formed on the positioning support rib 140 supports the control plate 400 and clamps the side of the positioning control plate 400, which can further improve the installation stability of the control plate 400.
[0033] In the above embodiment, the end cap 500 can also be fixed to the outer cylinder 150 by its outer side abutting against the inner side of the outer cylinder 150 through an interference fit. To further improve the structural stability of the end cap 500 installed in the outer cylinder 150, in this embodiment, multiple mounting protrusions 510 are formed on the outer side of the end cap 500, and these mounting protrusions 510 press against the inner side of the outer cylinder 150. When the end cap 500 is installed into the outer cylinder 150, the pressure exerted by the multiple mounting protrusions 510 against the inner side of the outer cylinder 150 is enhanced, making the connection between the end cap 500 and the outer cylinder 150 more stable.
[0034] Furthermore, a connecting sleeve 180 is provided inside the outer cylinder 150, and a connecting screw 520 is passed through the end cap 500, which is engaged with the connecting sleeve 180. After the end cap 500 is installed in place inside the outer cylinder 150, the connecting screw 520 can be passed through the end cap 500 and engaged with the connecting sleeve 180, thereby ensuring that the end cap 500 is securely installed inside the outer cylinder 150 and effectively preventing the end cap 500 from detaching from the outer cylinder 150.
[0035] The bracket is mainly used to connect to the structure of the peripheral device. In this embodiment, the bracket includes a slide rail 610 and a rotating rod 620 connected to the bottom side of the slide rail 610. The end cover 500 is rotatably connected to the bottom end of the rotating rod 620. In practical applications, the rotating rod 620 and the slide rail 610 can be detachably connected. For example, a threaded connector is connected to the bottom side of the slide rail 610, and an internal threaded cylinder is formed at the top of the rotating rod 620. The internal threaded cylinder is sleeved to the threaded connector, and the rotating rod 620 and the slide rail 610 are stably connected to each other by the threaded engagement. As for the connection between the rotating rod 620 and the end cover 500, a clearance space can be opened on one side of the end cover 500, and a connecting shaft is formed on the end cover 500 at the clearance space. The bottom end of the rotating rod 620 is connected to the connecting shaft, and the connecting shaft passes through the rotating rod 620 to realize the rotatable connection between the rotating rod 620 and the end cover 500. In use, the slide rail 610 is connected to the structure of the external device, such as a pre-installed track indoors. The relative angle between the heat sink 100 and the bracket can be adjusted by rotating the end cover 500, thereby adjusting the orientation of the light outlet 110. This allows for convenient adjustment of the light output direction and improves the flexibility of use.
