Description

Technical Field

[0001] This utility model relates to the field of spotlight technology, specifically to a spotlight with adjustable focusing range based on a single convex lens. Background Technology

[0002] Existing projectors are generally based on two structures: total internal reflection lenses and reflectors. These two structures have different drawbacks: total internal reflection lenses have a large angle after secondary optical design, which is difficult to be less than 10 degrees. They also have large particles, require more materials, and will result in severe yellow spots. Reflectors, on the other hand, require electroplating to achieve the required reflectivity. However, in accordance with my country's development path of green and environmentally friendly sustainable development, electroplating is not recommended because it requires a large amount of strong acid, strong alkali, heavy metal solutions, etc., which will cause serious environmental damage. Moreover, the beam angle of existing projectors is generally 30 degrees, making it difficult to obtain a large or small beam.

[0003] Chinese patent CN213686385U discloses a linear light projection lamp based on a single convex lens, including a housing, a light source, a first single convex lens, a second single convex lens, and a third single convex lens. By using a single convex lens instead of a conventional total internal reflection lens and reflector, the single convex lens has a more significant light-gathering ability, thus achieving the technical effect of linear light projection with a small angle.

[0004] When using the above-mentioned prior art, since the linear spotlight is fixed after installation, it is relatively troublesome to adjust the area illuminated by the light. Furthermore, since the linear spotlight is fixed, the illumination range of the entire lighting fixture cannot be adjusted as needed. Utility Model Content

[0026] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0027] See Figures 1 to 8 As shown, this utility model provides a spotlight with adjustable focusing range based on a single convex lens, including a mounting frame 1, a movable plate 2 on the mounting frame 1, a lampshade 3 mounted on the movable plate 2, a transverse driving component 4 for driving the movable plate 2 to move between the mounting frame 1 and the movable plate 2, a swing adjustment component 5 for adjusting the illumination range of the lampshade 3 on the movable plate 2, a light source 7 installed inside the lampshade 3, a first single convex lens 8 installed inside the lampshade 3 on one side of the light source 7, a second single convex lens 9 installed inside the lampshade 3 on one side of the first single convex lens 8, and a cleaning component 6 for cleaning the lamp head part of the lampshade 3 on one side of the mounting frame 1.

[0028] The horizontal drive component 4 drives the moving plate 2 to move, which in turn moves the lampshade 3, thereby increasing the illumination range of the spotlight. The illumination angle of the lampshade 3 can be adjusted by the swing adjustment component 5, so the illumination range of the entire lighting fixture can be adjusted as needed. It can adapt to various needs and has strong adaptability. When not in use, the lamp head of the lampshade 3 can be cleaned by the cleaning component 6 to prevent excessive dust from affecting the illumination effect.

[0029] See Figures 1 to 6 As shown, the swing adjustment assembly 5 includes an adjustment frame 51, a connecting plate 55, a first support frame 56, a second rotating rod 57, a second rotating block 58, and a third motor 59. The adjustment frame 51 is mounted on the moving plate 2. The connecting plate 55 is vertically swingable and mounted on the adjustment frame 51. The adjustment frame 51 is equipped with a vertical adjustment mechanism that drives the connecting plate 55 to swing. Both the adjustment frame 51 and the moving plate 2 are equipped with emergency stop mechanisms that precisely limit the angle of the lampshade 3. The first support frame 56 is mounted on the connecting plate 55. The second rotating rod 57 is located inside the first support frame 56. The second rotating block 58 is located on the second rotating rod 57 and is connected to the lampshade 3. The third motor 59 is located on one side of the first support frame 56, and the output end of the third motor 59 is connected to the second rotating rod 57.

[0030] By starting the third motor 59, the second rotating rod 57 is driven to rotate, and the second rotating block 58 is driven to rotate. Since the second rotating block 58 is connected to the lampshade 3, the third motor 59 drives the second rotating block 58 to rotate, thereby adjusting the horizontal illumination angle of the lampshade 3.

[0031] See Figure 3 As shown, the vertical adjustment mechanism includes a first rotating rod 52, a first rotating block 53, and a second motor 54; the first rotating rod 52 is disposed inside the adjustment frame 51; the first rotating block 53 is disposed on the first rotating rod 52 and is connected to the connecting plate 55; the second motor 54 is disposed on one side of the adjustment frame 51 and the output end of the second motor 54 is connected to the first rotating rod 52.

[0032] By starting the second motor 54, the first rotating rod 52 inside the adjusting frame 51 is rotated, and the first rotating rod 52 drives the first rotating block 53 to rotate. The first rotating block 53 then drives the connecting plate 55 to move, thereby adjusting the vertical illumination angle of the lampshade 3 by moving the connecting plate 55.

[0033] See Figure 6 As shown, the emergency stop mechanism includes an extension plate 510, a lead screw slide 511, a connecting block 512, a sleeve 513, an electric telescopic rod 514, and a ball 515. The extension plate 510 is mounted on the adjusting frame 51. The lead screw slide 511 is located on one side of the extension plate 510. The connecting block 512 is located at the working end of the lead screw slide 511. The sleeve 513 is located on the connecting block 512. The electric telescopic rod 514 is located inside the sleeve 513. The ball 515 is mounted at the working end of the electric telescopic rod 514.

[0034] By activating the electric telescopic rod 514, the ball 515 is moved to a suitable position. The electric telescopic rod 514 can also be moved along the extension plate 510 by activating the lead screw slide 511, thereby adjusting the position of the electric telescopic rod 514. This allows for precise adjustment of the position of the ball 515 by adjusting the angle of the lampshade 3 as needed.

[0035] The emergency stop mechanism also includes an infrared ranging sensor installed inside the sphere 515 and a controller mounted on the mounting bracket 1. The infrared ranging sensor is used to monitor the distance between the sphere 515 and the lampshade 3. Specifically, the infrared ranging sensor is not within the scope of protection of this application, so it is not shown in the figure. The infrared ranging sensor monitors the distance between the sphere 515 and the lampshade 3 in real time. When the lampshade 3 comes into contact with the sphere 515, the infrared ranging sensor transmits a signal to the controller. Since the second motor 54 and the third motor 59 are electrically connected to the controller, the controller sends a stop signal to the second motor 54 and the third motor 59 to stop the motors. Specifically, the controller is not within the scope of protection of this application, so it is not shown in the figure.

[0036] See Figure 2 As shown, the transverse drive assembly 4 includes a reciprocating lead screw 41, a first motor 42, and a first moving block 43; the reciprocating lead screw 41 is mounted on the mounting frame 1; the first motor 42 is located on one side of the mounting frame 1, and the output end of the first motor 42 is connected to the reciprocating lead screw 41; the first moving block 43 is located on the reciprocating lead screw 41, and the first moving block 43 is fixedly connected to the moving plate 2.

[0037] By starting the first motor 42, the reciprocating screw 41 is driven to rotate. The rotation of the reciprocating screw 41 drives the first moving block 43 to move. The first moving block 43 drives the moving plate 2 to move the lampshade 3, thereby enabling a wide range of adjustment of the illumination angle of the lampshade 3, which is highly practical.

[0038] See Figure 2 As shown, an extension block 44 is installed on the movable plate 2, and slide rods 45 are installed on both sides of the reciprocating screw 41 inside the mounting frame 1. The extension block 44 is slidably mounted on the slide rods 45.

[0039] When the first moving block 43 drives the moving plate 2 to move, the extension blocks 44 on both sides of the moving plate 2 slide on the slide rod 45, thereby making the moving plate 2 more stable when moving.

[0040] See Figure 5 As shown, a frosted sheet 10 is installed inside the lampshade 3 between the first convex lens 8 and the second convex lens 9.

[0041] By installing a frosted sheet 10 between the first convex lens 8 and the second convex lens 9, the problem of yellowing of the light spot emitted by the second convex lens 9 is solved, making the emitted light spot uniform and non-yellowing.

[0042] See Figure 7 and Figure 8 As shown, the cleaning assembly 6 includes a second support frame 61, a mounting plate 62, a swing rod 63, a fourth motor 64, a third rotating rod 65, a rectangular slider 66, and a cleaning brush 67. The second support frame 61 is mounted on one side of the mounting frame 1. The mounting plate 62 is mounted on the second support frame 61. The swing rod 63 is mounted on the mounting plate 62 via a rotating shaft. The fourth motor 64 is mounted on one side of the mounting plate 62. The third rotating rod 65 is mounted on the output end of the fourth motor 64. The rectangular slider 66 is rotatably mounted on the third rotating rod 65, and the rectangular slider 66 also has a through-hole for the swing rod 63 to move. The cleaning brush 67 is located on one side of the swing rod 63.

[0043] When the spotlight is not in use, the first motor 42 is started to move the movable plate 2 to one end of the mounting bracket 1. At this time, the fourth motor 64 is started, which drives the third rotating rod 65 to rotate. The rotation of the third rotating rod 65 drives the rectangular slider 66 to move. The movement of the rectangular slider 66 moves on the swing rod 63, which in turn drives the swing rod 63 to swing around the axis of rotation. The cleaning brush 67 set on one side of the swing rod 63 cleans the lamp head part of the lamp cover 3, thereby preventing the lamp head part of the lamp cover 3 from having too much dust, which would affect the illumination effect.

[0044] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
