Description

Technical Field

[0001] This application belongs to the field of lighting equipment technology, and more specifically, relates to a high-efficiency track light. Background Technology

[0002] Traditional track lights mostly use die-cast or riveted aluminum fins as heat sinks. Such heat sinks cannot quickly dissipate the heat from the light source, and the lights cannot maintain stable performance and light efficiency during long-term operation. Summary of the Invention

[0003] In order to overcome the above-mentioned shortcomings in the prior art, the purpose of this application is to provide a high-efficiency rail light with a simple and compact structure, which effectively reduces the working temperature of the light source module, avoids the luminous efficiency decay caused by high temperature, and ensures the stability of luminous efficiency.

[0004] The technical means adopted in this application to solve the above-mentioned technical problems are: This application provides a high-efficiency rail light, including: A lamp tube, wherein the inner wall at one end of the lamp tube is provided with threads; A radiator, comprising a main body and a heat sink, wherein the heat sink is disposed along the edge of the main body and abuts against the inner wall of the lamp tube; A light source module, wherein the light source module is mounted on the heat sink; A reflector is installed inside the lamp tube, and the reflector is correspondingly arranged with the light source module; The front ring has a threaded circumference and is threaded to one end of the lamp tube, and the front ring abuts against the reflector.

[0005] Preferably, it further includes a power driver, a connector, a rotating shaft, a rotating ring, and a rotating sleeve. The power driver is provided with a through hole, the rotating ring is installed in the through hole, the outer wall of the rotating sleeve is provided with a rotating groove, the rotating sleeve is rotatably installed on the rotating ring, and the rotating groove is engaged with the rotating ring; the rotating shaft is installed on the lamp tube, one end of the connector is rotatably connected to the rotating shaft, and one end of the connector is connected to the rotating sleeve.

[0006] Preferably, the lamp tube is provided with a mounting groove, the rotating shaft is mounted in the mounting groove, and the connector is inserted into the mounting groove.

[0007] Preferably, the inner wall of the lamp tube is provided with a positioning strip, and the heat sink is provided with a positioning groove corresponding to the positioning strip, and the positioning strip is inserted into the positioning groove.

[0008] Preferably, multiple heat sinks are provided, the main body has a cylindrical structure, and the multiple heat sinks are distributed along the edge of the main body.

[0009] Preferably, the heat sink is provided with heat dissipation blades.

[0010] Preferably, the heat dissipation blades have an arc-shaped structure similar to the circumferential surface of the lamp tube.

[0011] Compared with existing technologies, the high-efficiency rail light heat sink of this application adopts a main body and a heat sink structure set along the edge of the main body. The heat sink directly abuts against the inner wall of the lamp tube.

[0016] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0017] It should be noted that, unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. Similar reference numerals and letters denote similar items in the following figures; therefore, once an item is defined in one figure, it need not be further defined and explained in subsequent figures. Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0018] like Figures 1-2 As shown, this embodiment provides a high-efficiency rail light, including a lamp barrel 1, a heat sink 2, a light source module 3, a reflector 4, and a front ring 5. The inner wall of one end of the lamp barrel 1 is provided with threads; the heat sink 2 includes a main body and a heat dissipation body, the heat dissipation body is disposed along the edge of the main body, and the heat dissipation body abuts against the inner wall of the lamp barrel 1; the light source module 3 is installed on the heat sink 2; the reflector 4 is installed inside the lamp barrel 1, and the reflector 4 is correspondingly disposed with the light source module 3; the circumference of the front ring 5 is provided with threads, the front ring 5 is threadedly connected to one end of the lamp barrel 1, and the front ring 5 abuts against the reflector 4.

[0019] In some preferred embodiments of the present invention, a power driver 6, a connector 7, a rotating shaft 8, a rotating ring 9, and a rotating sleeve 10 are further included. The power driver 6 has a through hole, the rotating ring 9 is installed in the through hole, and the outer wall of the rotating sleeve 10 has a rotating groove. The rotating sleeve 10 is rotatably installed on the rotating ring 9, and the rotating groove is engaged with the rotating ring 9. The rotating shaft 8 is installed on the lamp tube 1, one end of the connector 7 is rotatably connected to the rotating shaft 8, and the other end of the connector 7 is connected to the rotating sleeve 10. Thus, through the dual rotation structure of the connector 7 rotatably connected to the rotating shaft 8 and the rotating sleeve 10 rotatably engaged with the rotating ring 9, multi-angle rotation of the lamp tube 1 around the rotating shaft 8 and the rotating sleeve 10 around the rotating ring 9 can be achieved. Compared with traditional fixed-angle rail lights, this can adapt to the angle requirements of different lighting scenarios. The rotating groove on the outer wall of the rotating sleeve 10 engages with the rotating ring 9, ensuring smooth rotation of the rotating sleeve 10 while limiting its axial displacement and preventing loosening during rotation. The through hole of the power driver 6 provides a stable mounting base for the rotating ring 9. The overall rotating structure is firmly assembled and not prone to failure during long-term use. The power driver 6 is integrated with the angle adjustment structure, eliminating the need for additional adjustment components, simplifying the overall structure and reducing assembly complexity.

[0020] In some preferred embodiments of the present invention, the lamp holder 1 is provided with a mounting groove, the rotating shaft 8 is mounted in the mounting groove, and the connector 7 is inserted into the mounting groove. Thus, the mounting groove of the lamp holder 1 provides precise positioning for the rotating shaft 8, preventing installation misalignment; the connector 7, inserted into the mounting groove, further enhances the assembly positioning effect, ensuring the assembly accuracy of the angle adjustment structure and reducing adjustment jamming problems caused by assembly misalignment. The connector 7, inserted into the mounting groove, makes the connection between the angle adjustment component and the lamp holder 1 more compact, reducing the overall space occupied and adapting to the miniaturization requirements of rail lights; simultaneously, the mounting groove can provide lateral restraint for the connector 7, enhancing structural stability.

[0021] In some preferred embodiments of the present invention, a positioning strip is provided on the inner wall of the lamp holder 1, and a positioning groove corresponding to the positioning strip is provided on the heat sink, with the positioning strip inserted into the positioning groove. Thus, the positioning strip of the lamp holder 1 and the positioning groove of the heat sink are inserted and cooperate to achieve precise positioning of the heat sink 2, avoiding the problem of loose contact between the heat sink and the inner wall of the lamp holder 1 due to installation misalignment of the heat sink 2, ensuring efficient thermal contact between the heat sink and the lamp holder 1, and maintaining a stable heat dissipation effect. The insertion and cooperation of the positioning strip and the positioning groove provide assembly guidance for the heat sink 2, allowing for installation of the heat sink 2 without repeated calibration, significantly improving production assembly efficiency and reducing assembly costs.

[0022] In some preferred embodiments of the present invention, multiple heat sinks are provided, and the main body has a cylindrical structure. The multiple heat sinks are distributed along the edge of the main body. Thus, the distribution of multiple heat sinks along the edge of the cylindrical main body, compared to a single heat sink or a traditional heat-conducting structure, increases the heat dissipation area in a ring-like diffusion pattern. Furthermore, the circumferential distribution ensures uniform heat transfer within the inner wall of the lamp tube 1, preventing localized heat accumulation and significantly accelerating heat dissipation from the light source module 3. The cylindrical main body has strong adaptability to the circular inner wall of the lamp tube 1, and the distribution of multiple heat sinks along the edge ensures uniform stress on the heat sink 2, resulting in more balanced contact with the inner wall of the lamp tube 1. This avoids structural deformation or loosening caused by uneven stress, extending the product's service life.

[0023] Specifically, a sunflower-shaped heat dissipation structure is adopted to increase the heat dissipation area, promote air convection, and improve heat dissipation efficiency. This ensures that the lamp maintains stable performance and luminous efficacy during long-term operation. Utilizing aerodynamic principles, the heat dissipation body features a finned structure with a fin spacing of 2-5 mm, allowing for smooth airflow between the fins and creating effective convection heat dissipation. Through mechanical calculations and simulation analysis, the heat sink structure is optimized to prevent deformation, breakage, and other problems. By designing heat dissipation and structural strength, the outer wall of the sunflower is tightly attached to the lamp housing, conducting some heat to the housing, while the remaining heat is dissipated into the air through the fins.

[0024] Furthermore, the center of the fin absorbs heat and emits heat to the fins radiating outwards. Air flows in from the top and flows directly through the extended fin blades inside, absorbing a large amount of heat during the airflow. Because the fin blades are in a regular radial shape, there is no significant obstruction to the airflow direction, or rather, the uniform radiation of the fin blades creates a uniform and smooth space with low overall wind resistance.

[0025] The above technologies improve the overall lamp efficiency from 70% to 83%, with the light source's CRI80 increasing from CRI80 to CRI90, the light source's bare luminous efficacy increasing from 140LM / W to 215LM / W, the reflector efficiency increasing from 88% to 95%, and the driver power supply efficiency increasing from 88% to 92%. With the addition of a good heat sink, the overall lamp efficacy increases from 120LM / W at CRI80 to 170LM / W at CRI90.

[0026] In some preferred embodiments of the present invention, the heat sink is provided with heat dissipation fins. Thus, the addition of heat dissipation fins further increases the surface area of ​​the heat sink, and the fins can form natural convection channels, promoting airflow within the gaps between the fins and accelerating heat exchange with the air. Compared to a heat sink without fins, the heat dissipation efficiency is significantly improved. Simultaneously, the fin structure strengthens the structural strength of the heat sink, preventing deformation due to prolonged high temperatures.

[0027] In some preferred embodiments of the present invention, the heat dissipation blade has an arc-shaped structure similar to the circumferential surface of the lamp tube 1. Thus, by adopting an arc-shaped structure similar to the circumferential surface of the lamp tube 1, the heat dissipation blade fits better against the inner wall of the lamp tube 1, further increasing the thermally conductive contact area and improving the efficiency of heat transfer from the heat sink to the lamp tube 1. Furthermore, the arc-shaped structure reduces airflow resistance, allowing for smoother air convection between the heat dissipation blade and the lamp tube 1, enhancing the convective heat dissipation effect. Simultaneously, the arc-shaped design makes the assembly of the heat sink and the lamp tube 1 more snug, improving the overall structural compactness.

[0028] Compared with existing technologies, the high-efficiency rail light heat sink 2 of this application adopts a main body and a heat sink structure set along the edge of the main body, and the heat sink directly abuts against the inner wall of the lamp tube 1. Compared with traditional die-cast or riveted aluminum sheet heat conductors, it significantly increases the heat dissipation area and heat conduction contact area. Heat can be quickly transferred to the lamp tube 1 through the heat sink and dissipated outward, effectively reducing the working temperature of the light source module 3 and avoiding luminous efficiency decay caused by high temperature. The inner wall thread of one end of the lamp tube 1 is engaged with the circumferential thread of the front ring 5, which can not only achieve a stable connection between the front ring 5 and the lamp tube 1, but also achieve precise positioning of the reflector 4 by the front ring 5 abutting against the reflector 4, avoiding the problem of easy loosening in traditional fixing methods; at the same time, the light source module 3 is directly installed on the heat sink 2, shortening the heat conduction path and further enhancing the heat dissipation effect.
