Description

A right-angled parallel coaxial light source Technical Field

[0001] This utility model relates to the technical field, specifically to a right-angled parallel coaxial light source. Background Technology

[0002] Visual inspection requires cameras for imaging and light sources (such as right-angle parallel coaxial light sources) to illuminate the inspected object, resulting in clearer images and facilitating further analysis. Right-angle parallel coaxial light sources provide more uniform illumination than traditional light sources and are therefore widely used in visual inspection systems.

[0003] Currently, the right-angled parallel coaxial light source used for visual inspection work usually has a fixed structure for light reflection and deflection. As a result, the light emitted into the external environment has fixed intensity, concentration, position, and angle, which is relatively simple and cannot meet various complex practical needs. Summary of the Invention

[0004] The purpose of this invention is to provide a right-angle parallel coaxial light source, which has the advantage of being able to easily change the intensity, concentration, position and angle of the light emitted from the light-emitting cover plate in order to meet the actual lighting needs under different conditions, and solves the problem that existing coaxial light sources cannot meet various complex actual needs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a right-angle parallel coaxial light source, comprising an integrally mounted base plate, a content seat, and a top plate, as well as an extension tube and a lamp bead shell located on the content seat. A light-emitting cover plate is installed on the top plate, wherein the extension tube is fixedly installed on one side wall of the content seat, and the lamp bead shell is threaded onto the extension tube. The fixing method between the base plate, the content seat, and the top plate, as well as the fixing method of the extension tube on the content seat, can be bolt installation or other fixing methods.

[0006] A steering shaft is connected to the side of the inner cavity of the content holder that faces away from the lamp bead shell, and a reflector is provided on the steering shaft. The reflector is integrally welded from an upper plate and a lower plate. The upper plate is fixedly sleeved on the steering shaft. The angles of the upper plate facing the expansion cylinder and the lower plate facing the expansion cylinder are different, so that the light emitted by the lamp bead shell is placed on the upper plate and the lower plate, and the light reversal is also different. This allows the light to make more complex angle reversals in the content holder, so that the range of light emitted from the light-emitting cover is larger, thereby improving the illumination range. Multiple reflective inner grooves are formed on both the upper plate and the lower plate, and the reflective inner grooves have multiple reversing inner walls.

[0007] A knob is rotatably connected to the bottom wall of the base plate. A protruding seat is welded to the bottom wall of the inner cavity of the base plate. A moving groove is formed from the top wall of the protruding seat to the inside of the base plate. A screw is coaxially connected above the knob. A lifting seat is threaded onto the screw. The lifting seat fits against the inner wall of the protruding seat, so that when the screw is turned, it can drive the lifting seat to rise and fall within the protruding seat. A connecting shaft is provided above the lifting seat, and the lifting seat is connected to the lower plate through the connecting shaft. When the lifting seat rises and falls, it can drive the upper and lower plates to rotate with the steering shaft, thereby changing the direction of the light emitted by the lamp bead shell. It is worth noting that there are two connecting shafts on the lifting seat. The two connecting shafts are connected by a strip plate. When the lifting seat rises and falls, the two connecting shafts rotate accordingly, thereby supporting the upper plate to rotate smoothly with the steering shaft.

[0008] As a preferred embodiment: a wire is fixedly connected to the side of the lamp bead shell facing away from the inner socket; in actual design, the length of the wire is determined as needed, and power is transmitted to the lamp bead shell through the wire, so that the lamp bead shell emits light source to illuminate the inner socket, and then emits light through the light-emitting cover plate.

[0009] As a preferred embodiment: the multiple reflective inner grooves on the upper or lower plate are designed with equal spacing, and the multiple turning inner walls in each reflective inner groove have different angles; thus facilitating the generation of complex light turning, and each reflective inner groove is provided with at least four turning inner walls with different angles.

[0010] As a preferred embodiment: a bottom cover is fixedly bonded to the bottom wall of the base plate, wherein the knob is located inside the bottom cover; and the design of the bottom cover does not affect the rotation of the knob, thereby protecting the knob through the bottom cover.

[0011] As a preferred embodiment: the screw is vertically installed in the protruding seat, and the bottom of the screw extends into the moving groove and is rotatably connected to the base plate; so that the screw can operate stably under the action of the knob.

[0012] As a preferred embodiment: the inner cavity of the light-emitting cover is connected to the inner cavity of the content holder, and a light-transmitting sheet is sealed at the opening at the top of the light-emitting cover; the inner cavity of the content holder can be completely sealed through the light-transmitting sheet, thereby preventing external dust and other objects from entering the content holder.

[0013] As a preferred embodiment, the opening inside the expansion tube is enlarged from the side closest to the lamp bead housing to the side furthest from the lamp bead housing, thereby facilitating the expansion of the light reflection range.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This utility model, by designing different angles on the light-receiving sides of the upper and lower plates, produces more complex light reversals when light shines on the upper and lower plates. In addition, both the upper and lower plates are provided with multiple reflective inner grooves, making the light reversals on the reflector more diverse and dispersed, thereby avoiding the problem of excessive brightness caused by excessive light concentration. Furthermore, the dispersed light can expand the illumination range.

[0016] This invention features four angled inner walls in each reflective groove, and a knob that rotates to flip the reflector, changing the angle at which the reflector bends the light. This allows for adjustments to the intensity, concentration, position, and angle of the light emitted from the light-emitting cover, thus meeting the actual lighting needs under different conditions.

Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0025] Please refer to Figures 1 to 4. This utility model provides a right-angled parallel coaxial light source, comprising an integrally mounted base plate 1, a content holder 2, and a top plate 3, as well as an extension tube 4 and a lamp bead housing 5 located on the content holder 2. A light-emitting cover plate 7 is mounted on the top plate 3. The extension tube 4 is fixedly mounted to one side wall of the content holder 2, and the lamp bead housing 5 is threaded onto the extension tube 4. The internal structure of the extension tube 4 increases in size from the side closest to the lamp bead housing 5 to the side furthest from it, thereby facilitating the expansion of the light reflection range. The fixing methods of the base plate 1, content holder 2, and top plate 3, as well as the fixing method of the extension tube 4 on the content holder 2, are all... The installation can be done by bolts or other fixing methods. A wire 6 is fixedly connected to the side of the lamp bead shell 5 facing away from the inner seat 2. In actual design, the length of the wire 6 is determined as needed. Power is transmitted to the lamp bead shell 5 through the wire 6, so that the lamp bead installed in the lamp bead shell 5 emits light and illuminates the inner seat 2 (the installation method, technical principle, model, etc. of the lamp bead are all existing). The inner cavity of the light-emitting cover plate 7 is connected to the inner cavity of the inner seat 2, and a light-transmitting sheet 17 is sealed at the opening at the top of the light-emitting cover plate 7. The inner cavity of the inner seat 2 can be completely sealed through the light-transmitting sheet 17, thereby preventing dust and other objects from entering the inner seat 2.

[0026] A steering shaft 8 is connected to the side of the inner cavity of the inner socket 2 facing away from the lamp bead housing 5, and a reflector 9 is provided on the steering shaft 8. The reflector 9 is integrally welded together by an upper plate 901 and a lower plate 902. The upper plate 901 is fixedly sleeved on the steering shaft 8. The angles of the upper plate 901 facing the expansion cylinder 4 and the lower plate 902 facing the expansion cylinder 4 are different, so that the light emitted by the lamp bead housing 5 is positioned on the upper plate 901 and the lower plate 902, and the light is deflected differently. This allows the light to undergo more and more complex angle deflections within the inner socket 2. This allows the light to travel a wider range when it is emitted from the light-emitting cover plate 7, thereby improving the illumination range. Multiple reflective inner grooves 903 are formed on both the upper plate 901 and the lower plate 902. Each reflective inner groove 903 has multiple turning inner walls 904. The multiple reflective inner grooves 903 on the upper plate 901 or the lower plate 902 are designed with equal spacing, and the angles of the multiple turning inner walls 904 in each reflective inner groove 903 are different, which facilitates the generation of complex light turning. Each reflective inner groove 903 has at least four turning inner walls 904 with different angles.

[0027] A knob 11 is rotatably connected to the bottom wall of the base plate 1. To protect the knob 11, a bottom cover 10 is fixedly bonded to the bottom wall of the base plate 1. The knob 11 is located inside the bottom cover 10, and the design of the bottom cover 10 does not affect the rotation of the knob 11, thus protecting the knob 11. A protruding seat 12 is welded to the bottom wall of the inner cavity of the base plate 1. A moving groove 13 is formed from the top wall of the protruding seat 12 to the inside of the base plate 1. A screw 14 is coaxially connected above the knob 11. The screw 14 is vertically set inside the protruding seat 12, and the bottom of the screw 14 extends into the moving groove 13 and is rotatably connected to the base plate 1, so that the screw 14 can operate stably under the drive of the knob 11. A lifting seat 15 is threaded onto the screw 14. The middle lifting seat 15 fits against the inner wall of the protruding seat 12, so that when the screw 14 is running, it can drive the lifting seat 15 to rise and fall within the protruding seat 12. A connecting shaft 16 is provided above the lifting seat 15, and the lifting seat 15 is connected to the lower plate 902 through the connecting shaft 16. When the lifting seat 15 rises and falls, it can drive the upper plate 901 and the lower plate 902 to rotate with the steering shaft 8, thereby changing the direction of the light emitted by the lamp bead housing 5 after the deflection. It is worth noting that there are two connecting shafts 16 on the lifting seat 15. The two connecting shafts 16 are connected by a strip plate. When the lifting seat 15 rises and falls, the two connecting shafts 16 rotate accordingly, thereby supporting the upper plate 901 to rotate smoothly with the steering shaft 8.

[0028] Working principle: In operation, the wire 6 supplies power to the LED inside the LED housing 5. After the LED is powered on, it emits light into the inner socket 2. When the light enters the inner socket 2, it is deflected upwards by the upper plate 901 and the lower plate 902, and then enters the light-emitting cover 7 and passes through the light-transmitting sheet 17 to be emitted to the outside. In actual use, the angle of the reflector 9 can be adjusted as needed. During adjustment, the knob 11 is turned by reaching into the bottom cover 10, which drives the screw 14 to rotate, causing the lifting seat 15 to rise and fall with the inner wall of the protruding seat 12. This causes the upper plate 901 and the lower plate 902 to rotate with the steering shaft 8, thereby changing the angle of all light deflection. At the same time, after the light enters the reflective inner groove 903, its path is changed by the deflecting inner wall 904, making the light produce more complex deflections, so as to produce different light deflection effects to meet actual needs.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
