Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a rail spotlight. Background Technology

[0002] Track lighting, also known as LED track lighting, is a type of lighting device that uses LED light sources and is installed on a track. It can generally freely adjust the angle of light projection to create a layered lighting effect. It can solve the lighting requirements of both basic lighting and highlighting key areas, and has been widely used in various lighting scenarios, such as product display lighting, interior decoration, and outdoor lighting.

[0003] Currently, common track lights are generally cylindrical track lights, which can be adjusted horizontally by 355 degrees and vertically, facilitating the movement of the light heads for precise lighting. However, a single cylindrical track light can typically only illuminate one area. If multiple areas need illumination, multiple cylindrical track lights are required, leading to higher costs. To improve the lighting range, some long, narrow track lights, such as magnetic spotlights, are also available. While existing magnetic spotlights are easy to move and have a larger illumination range, they pose a risk of falling. Furthermore, because magnetic spotlights can only move along the track and cannot change the lighting angle, their illumination range is relatively fixed, and the beam angle cannot be further adjusted. Moreover, existing magnetic spotlights cannot adjust the number of illumination points according to lighting needs, resulting in limited functionality and poor practicality.

[0004] Therefore, there is an urgent need to design a rail spotlight that can be stably fixed on a rail and can stay at any position on the rail for a long time, effectively avoiding the danger of falling. At the same time, the angle of the rail spotlight can be adjusted to increase the projection area, and multiple areas can be lit simultaneously according to actual illumination needs, so as to meet the multi-level and multi-directional lighting needs of the rail spotlight. It should also have a compact structure and be highly practical. Utility Model Content

[0010] In a preferred embodiment of this application, the radiator further includes a plurality of convection channels; the plurality of convection channels are disposed on the inner sidewall of the radiator dome and are connected to both ends of the radiator.

[0011] In a preferred embodiment of this application, the light source assembly includes a light source mounting substrate, a light source, and a light source reflector; the light source mounting substrate is inserted into the heat sink; the light source is disposed on the light source mounting substrate; and the light source reflector is disposed on one side of the light source.

[0017] (1) The rail spotlight provided in this application includes a rail assembly, a power supply assembly, and a lamp body. By separating and independently setting the power supply and the light source, heat conduction between the power supply and the light source can be reduced, thereby facilitating the heat sink to dissipate the heat generated by the light source. Furthermore, by setting convection grooves on the heat sink, the heat dissipation effect is effectively improved, reducing the instability around the light source and thus reducing light decay. By setting a stop and a toggle lever on the rail head, when the toggle lever is pushed to move counterclockwise or clockwise, the mounting shaft can be driven to rotate counterclockwise or clockwise, thereby fixing the rail head on the rail.

By mounting the rail box on the fixed shaft of the end cover baffle, the lamp body can rotate 180 degrees relative to the rail box and the power supply box, expanding the illumination range and angle of the rail spotlight to adapt to different scenarios. Compared with existing rail spotlights, the solution of this application can further adjust the angle of the rail spotlight, increase the projection area, and simultaneously illuminate multiple areas according to actual illumination needs, so as to meet the multi-level and multi-directional lighting needs of the rail spotlight. It also has a compact structure and strong practicality.

[0032] While existing strip spotlights are easy to move and have a wide illumination range, they pose a risk of falling. Furthermore, because strip spotlights can only move along the track and cannot change the illumination angle, their illumination range is relatively fixed, and the beam angle cannot be further adjusted. Additionally, existing magnetic spotlights cannot adjust the number of illumination points according to lighting needs, resulting in limited functionality and poor practicality.

[0033] To address the aforementioned issues, this application provides a rail spotlight that can be stably fixed on a rail and remain at any position on the rail for an extended period, effectively avoiding the danger of falling. Simultaneously, the angle of the rail spotlight can be adjusted to increase the projection area, and multiple areas can be simultaneously illuminated according to actual lighting needs, satisfying the multi-layered and multi-directional lighting requirements of the rail spotlight. Furthermore, it has a compact structure and strong practicality.

[0034] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0035] Example

[0036] Please see Figures 1-6 The rail spotlight of this application includes a rail assembly 1, a power supply assembly 2, and a lamp body 3. The rail assembly 1 is slidably disposed in the rail and is used to adjust the position of the rail spotlight on the rail. The power supply assembly 2 is disposed parallel to the lamp body 3 in the middle of the two rail assemblies 1. The power supply assembly 2 is used to drive the lamp body 3 so that the lamp body 3 emits light.

[0037] Specifically, the guide rail assembly 1 includes a guide rail box 11 and a guide rail head 12. To improve the strength of the guide rail assembly 1 and ensure the stability of the guide rail spotlight installation, the guide rail box 11 and the guide rail head 12 are made of aluminum alloy. The guide rail box 11 is located at both ends of the power supply assembly 2 and is connected to the lamp body 3. Figure 1 As shown, the guide rail box 11 includes a body 111, a box base 112, and an insert block 113. The body 111 is generally rectangular, and an insert rod 1111 is provided inside the body 111. The upper surface of the box base 112 is provided with an insert sleeve 1121 that is adapted to the insert rod 1111. By inserting the insert rod 1111 into the insert sleeve 1121, the box base 112 is fixed to the body 111. Specifically, the box base 112 includes a horizontal base plate and a vertical plate. The vertical plate is disposed on the end side of the horizontal base plate, making the box base 112 generally inverted L-shaped. The insert sleeve 1121 is disposed on the horizontal base plate. The plug 113 is disposed on the end side of the body 111 and is used to connect the power supply assembly 2. Specifically, the plug 113 includes a first plug, a second plug and a third plug. The first plug and the second plug are arranged in parallel and symmetrically. The third plug is disposed between the first plug and the second plug and is located above the first plug and the second plug.

[0038] like Figure 1 and Figure 4 As shown, the guide rail head 12 includes a mounting shaft 121, a toggle lever 122, and a stop block 123. The mounting shaft 121 is embedded at the top of the guide rail box 11. The toggle lever 122 is sleeved on the lower end of the mounting shaft 121 and is used to drive the mounting shaft 121 to rotate. The stop block 123 is symmetrically arranged on the top side of the mounting shaft 121. Specifically, the mounting shaft 121 is rotatably disposed at the top of the body 111, and the axial direction of the mounting shaft 121 is perpendicular to the horizontal base plate. The toggle lever 122 is fixedly connected to the mounting shaft 121. When the user pushes the toggle lever 122 counterclockwise or clockwise, it can drive the mounting shaft 121 to rotate counterclockwise or clockwise. The stop block 123 includes a first stop block and a second stop block. The first stop block and the second stop block are arc-shaped and adapted to the mounting shaft 121. When the line connecting the first stop and the second stop is parallel to the length direction of the guide rail, the guide rail head 12 can slide along the length direction of the guide rail. At this time, when the mounting shaft 121 is rotated 90 degrees counterclockwise or clockwise, the line connecting the first stop 123 and the second stop 123 is perpendicular to the length direction of the guide rail and abuts against the guide rail, thereby fixing the guide rail head 12 on the guide rail, so that the entire guide rail spotlight can be fixed at any position on the guide rail and stay there for a long time.

[0039] The power supply assembly 2 includes a power supply box 21 and a power source. Both ends of the power supply box 21 are connected to the guide rail box 11. The power source is housed within the power supply box 21 and connected to the lamp body 3. Specifically, the power supply box 21 is generally a square tube. Slots for insert blocks 113 are provided at both ends of the power supply box 21, allowing the box base 112 to be connected to the power supply box 21 via the insert blocks 113. The power source is placed inside the power supply box 21, and its power cord is connected to the light source 34 of the lamp body 3 through a through-hole.

[0040] The lamp body 3 is positioned directly below the power supply box 21. Specifically, the lamp body 3 includes a heat sink 31, a light source assembly, and end caps 32. The light source assembly is disposed within the heat sink 31, and the end caps 32 are located at both ends of the heat sink 31. Figures 1-3 As shown, the heat sink 31 is generally arched, and it also includes several convection channels 311. These channels 311 are located on the inner wall of the arch of the heat sink 31 and communicate with both ends of the heat sink. By providing the convection channels 311, the contact area between the heat sink 31 and the hot air (generated by the light source 34) can be increased, thereby improving the heat dissipation effect, reducing the heat around the light source 34, and decreasing light decay. To further improve the heat dissipation effect, the heat sink 31 is made of pure aluminum forging.

[0041] The light emission direction of the light source assembly is away from the dome of the heat sink 31. Specifically, the light source assembly includes a light source mounting base 33, a light source 34, and a light source reflector 35. The light source mounting base 33 is inserted into the heat sink 31, and the light source 34 is disposed on the light source mounting base 33, with the light emission direction of the light source 34 facing the opening end of the heat sink 31 (i.e., the opposite side of the dome). The light source reflector 35 is disposed on one side of the light source 34 and is used to control the beam direction and angle of the spotlight, so that the light produces a softer and more uniform light and shadow effect. The light source diffuser 36 is disposed directly opposite the light source 34 and is located between the light source mounting base 33 and the light source reflector 35, and is connected to both the light source mounting base 33 and the light source reflector 35, respectively, to disperse the light to a larger area, distribute the light evenly, avoid glare, and increase the comfort and visual effect of the light.

[0042] For example, the light source mounting substrate 33 is an aluminum substrate, and the heat sink 31 has arc-shaped slots on its two opposing inner sidewalls, into which the light source mounting substrate 33 is inserted. Figure 1As shown, the overall shape of the light source diffuser 36 is hopper-shaped, with the top area of ​​the diffuser 36 being larger than the bottom area. The diffuser 36 completely covers the light source 34, allowing all light sources 34 to pass through, thus maximizing the utilization rate of the light sources 34. The overall shape of the light source reflector 35 is frustum-shaped, meaning the bottom area of ​​the reflector 35 is larger than its top area, and the top area of ​​the reflector 35 is larger than the bottom area of ​​the diffuser 36. Therefore, when light emitted from the light source 34 passes through the diffuser 36, it can all pass through the reflector 35, thus projecting the light outwards.

[0043] Furthermore, to allow adjustment of the lighting point according to the user's actual needs, the light source 34 includes N LEDs, which are arranged sequentially along the length of the light source mounting substrate 33. For example, N is 10. By adjusting parameters such as the power of the 10 LEDs, two LEDs can be projected onto the same point, or five LEDs can be projected onto the same point, thus achieving the effect of 2, 5, or 10 projections from the same spotlight. This effectively matches various application scenarios and greatly improves the practicality of the rail spotlight. Correspondingly, N light source diffusers 36 and N light source reflectors 35 are each provided. The N light source diffusers 36 correspond one-to-one with the N LEDs, and the N light source reflectors 35 correspond one-to-one with the N light source 34 diffuser plates.

[0044] like Figure 1 As shown, the end cap baffle 32 is disposed at both ends of the heat sink 31. Specifically, the end cap baffle 32 includes an end cap body 321, a pin 322, and a fixing shaft 323. The pin 322 is disposed on the inner side wall of the end cap body 321 and is perpendicular to the end cap body 321. The pin 322 is inserted into the heat sink 31, thereby fixing the end cap body 321 to the heat sink 31. The fixing shaft 323 is disposed on the outer side wall of the end cap body 321 and is rotatably connected to the guide rail box 11. More specifically, the vertical plate of the guide rail box 11 is provided with a mounting through hole adapted to the fixing shaft 323, so that the vertical plate is sleeved on the fixing shaft 323 through the mounting through hole, allowing the lamp body 3 to rotate 180 degrees about the fixing shaft 323 (e.g., rotating the lamp body 3 clockwise or counterclockwise 90 degrees), thereby expanding the range and angle of the guide rail spotlight. To prevent the vertical plate from slipping off the fixed shaft 323, in practical applications, the box base 112 can be limited to the end cover baffle 32 by passing screws through the mounting through hole and the mounting shaft 121.

[0045] In this embodiment, the rail spotlight provided by this application includes a rail assembly, a power supply assembly, and a lamp body. By separating and independently setting the power supply and the light source, heat conduction between the power supply and the light source can be reduced, thereby facilitating the heat sink to dissipate the heat generated by the light source. Furthermore, by setting convection grooves on the heat sink, the heat dissipation effect is effectively improved, reducing instability around the light source and thus reducing light decay. By setting a stop and a toggle lever on the rail head, when the toggle lever is pushed counterclockwise or clockwise, the mounting shaft can be rotated counterclockwise or clockwise, thereby fixing the rail head on the rail. This allows the entire rail spotlight to be fixed at any position on the rail and remain stationary for a long time, effectively avoiding the danger of the rail spotlight falling. By setting multiple LEDs, a light source diffuser, and a light source reflector, the power and other parameters of the multiple LEDs can be adjusted to achieve the effect of 2, 5, or 10 projections from the same rail spotlight, effectively matching various application scenarios and greatly improving the practicality of the rail spotlight. By mounting the guide rail box on the fixed shaft of the end cover baffle, the lamp body can rotate 180 degrees relative to the guide rail box and the power supply box, thereby expanding the range and angle of the guide rail spotlight to adapt to different scenarios.
