Description

Technical Field

[0001] The utility model relates to the technical field of light sources, in particular to a ring-shaped light source structure. Background Art

[0002] Light sources can be divided into natural light sources (natural light sources) and artificial light sources. The sun, turned on electric lights, burning candles, etc. are all light sources.

[0003] Machine vision imaging requires a light source. When using a light source, most internal illuminators shine directly outward. This prevents the light from being effectively focused, resulting in scattered light and a lack of high illumination intensity, hindering subsequent machine vision imaging. Therefore, to address this issue, we propose a ring-shaped light source structure. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a ring-shaped light source structure.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A ring-shaped light source structure includes a reflective shell, a light board connected to the bottom of the reflective shell, and a plurality of LED lamp beads connected to the top of the light board. The inner wall of the reflective shell is provided with an elliptical reflective surface. The LED lamp beads serve as light-emitting poles. The LED light paths emitted by the plurality of light-emitting poles converge at a focusing pole after being reflected by the elliptical reflective surface.

[0007] Preferably, the external threaded sleeve of the reflective shell is provided with a dust shield, the bottom of the dust shield is inlaid with light-transmitting glass, and the dust shield is also sleeved on the outside of the lamp panel.

[0008] Preferably, a cooling fan is installed at the center of the top of the reflective shell, and a protective cover is connected to the top of the reflective shell and located outside the cooling fan.

[0009] Preferably, a flow window is opened through the center of the top of the protective cover, a filter is connected to the inside of the flow window, and L-shaped mounting brackets are connected to the four corners of the top of the protective cover, and mounting holes are opened through the L-shaped mounting brackets.

[0010] Preferably, the elliptical reflective surface is coated with a reflective agent.

[0011] Preferably, a heat dissipation window is provided through the center of the top of the reflective shell.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] This utility model utilizes a reflective housing, LED lamp beads, a lamp panel, an elliptical reflective surface, a light-emitting pole, and a light-collecting pole. The light generated by the LED lamp beads is irradiated on the elliptical reflective surface, which then reflects the light, focusing it at a single point and increasing the brightness of the light source. Furthermore, a cooling fan operates intermittently during operation of the LED lamp beads, extracting heat from the reflective housing through the heat dissipation window. Ultimately, the hot air is discharged through the flow window, thereby extending the service life of the annular light source structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] See also Figures 1-6, a ring-shaped light source structure includes a reflective shell 2, the bottom of the reflective shell 2 is connected to a lamp board 8, the top of the lamp board 8 is connected to several LED lamp beads 7, the inner wall of the reflective shell 2 is provided with an elliptical reflective surface 9, the LED lamp beads 7 serve as the light-emitting pole 13, and the LED light paths emitted by the several light-emitting poles 13 converge at the focusing pole 12 after being reflected by the elliptical reflective surface 9; the light source is reflected by the elliptical reflective surface 9 to concentrate the light source and improve the brightness; the color of the LED lamp beads 7 can be adjusted according to actual needs. If it is an ultraviolet LED, it is an ultraviolet light source, an infrared LED is an infrared light source, a green LED is a green light source, and so on; elliptical reflection is that the light emitted from one focus of the ellipse will pass through another focus after elliptical reflection. This is an important optical property of the ellipse, indicating that the reflection of light on the ellipse follows a specific law. The elliptical reflection theorem is used in optics to achieve specific light transmission and focusing effects.

[0023] As a technical optimization solution of the present invention, the outer threaded sleeve of the reflector shell 2 is provided with a dust shield 1, and the bottom of the dust shield 1 is inlaid with a transparent glass 10, which is also mounted on the outside of the light panel 8. The transparent glass 10 facilitates the transmission of light reflected by the elliptical reflective surface 9 through the dust shield 1. The transparent glass 10 is ultra-clear glass, which is a type of ultra-transparent low-iron glass, also known as low-iron glass or high-transparency glass. It is a high-quality, multifunctional, new high-end glass with a light transmittance of over 91.5%, providing a brighter and clearer field of view, and is particularly suitable for use in places requiring high transparency. At the same time, because the ultra-clear glass contains very few impurities, especially impurities such as nickel sulfide that cause self-explosion, its self-explosion rate can be reduced to about one in ten thousand, greatly improving safety. Furthermore, because ultra-clear glass has few internal impurities and good thermal conductivity, heat inside the reflector shell 2 and the dust shield 1 can also be quickly transferred to the outside through the transparent glass 10.

[0024] As a technical optimization solution of the present invention, a cooling fan 11 is installed at the center of the top of the reflecting shell 2, and a protective cover 3 is connected to the top of the reflecting shell 2 and on the outside of the cooling fan 11; through the cooperation of the cooling fan 11 and the cooling window 6, the heat gathered in the reflecting shell 2 can be conveniently taken away; the cooling fan 11 can be protected by the protective cover 3 to prevent the cooling fan 11 from being exposed to the outside as a whole, which makes it easy to be damaged; further, the cooling window 6 can be shielded by the protective cover 3 to prevent a large amount of dust from rising from the cooling window 6 and falling into the reflecting shell 2, causing the elliptical reflecting surface 9 to be contaminated, making it unable to reflect light efficiently.

[0025] As a technical optimization solution of the present invention, a flow window is opened through the center of the top of the protective cover 3, and a filter screen 5 is connected to the inside of the flow window. The four corners of the top of the protective cover 3 are connected to an L-shaped mounting bracket 4, and a mounting hole is opened through the L-shaped mounting bracket 4; through the cooperation between the L-shaped mounting bracket 4 and the mounting hole, it is convenient for the bolt to pass through the mounting hole to position the L-shaped mounting bracket 4 and install it on the mounting platform; through the filter screen 5, the air can be filtered to prevent a large amount of external dust from falling into the reflective shell 2 when the cooling fan 11 is not in use, and also to prevent some small animals from entering the reflective shell 2 and damaging the LED lamp beads 7.

[0026] As a technical optimization solution of the present invention, the elliptical reflective surface 9 is coated with a reflective agent.

[0027] As a technical optimization solution of the present invention, a heat dissipation window 6 is provided through the center of the top of the reflective shell 2 .

[0028] When the present invention is in use, a number of LED lamp beads 7 are arranged in a ring around a central point. This arrangement ensures that light is emitted evenly from all directions, and the ring layout allows light to illuminate the elliptical reflective surface 9 from multiple angles, thereby improving light utilization and focusing effects. Furthermore, since a number of LED lamp beads 7 are arranged in a ring, the angles of light emitted by LED lamp beads 7 at different positions will naturally be different. The light emitted by each LED lamp bead 7 will illuminate the elliptical reflective surface 9 at a specific angle. This multi-angle light emission method can cover a wider reflective surface area, allowing more light to be captured and concentrated by the reflective surface. The light emitted by LED lamp beads 7 at different positions will eventually converge on the focusing point after being reflected by the elliptical reflective surface 9. By concentrating the scattered light to one point, the brightness of the light source is significantly improved, forming a high-brightness focusing point. Due to the circular arrangement and multi-angle emission of the lamp beads, the reflected light is more evenly distributed, avoiding local overbrightness or overdarkness. The translucent glass 10 is ultra-white glass, an ultra-transparent low-iron glass with a light transmittance of over 91.5%, which can provide a brighter and clearer field of view. Because ultra-white glass has few internal impurities and good thermal conductivity, the heat inside the reflective shell 2 and the dust shield 1 can also be quickly transferred to the outside through the translucent glass 10. During the operation of the LED lamp beads 7, the cooling fan 11 runs intermittently, using the cooling fan 11 to extract the heat inside the reflective shell 2 through the heat dissipation window 6, and finally the hot air is discharged through the flow window, thereby extending the service life of the annular light source structure. The protective cover 3 is beneficial for protecting the cooling fan 11, preventing the cooling fan 11 from being exposed to the outside and causing damage. Furthermore, the protective cover 3 can shield the heat dissipation window 6, preventing a large amount of dust from falling into the reflective shell 2 and causing the elliptical reflective surface 9 to be contaminated, making it unable to reflect light efficiently.

[0029] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
