Description

Technical Field

[0001] This utility model relates to the technical field of laser light adjustment, specifically a laser light with beam size adjustment function. Background Technology

[0002] Laser illumination is divided into visible light laser illumination and infrared laser illumination. Visible light laser illumination, based on its principle, can be further divided into two types: 1. Blue light excites phosphors to achieve white light illumination; 2. Red, green, and blue lasers are combined to create white laser light, or true-color light illumination. Infrared laser illumination is mostly used in night vision and night-time camera surveillance lighting.

[0003] Existing laser lights typically employ beam size adjustment mechanisms that combine a convex lens with a laser light distance adjustment device. This device adjusts the distance between the laser light and the convex lens, thereby using light refraction to adjust the beam size. However, the convex lenses in most existing laser lights are fixedly installed inside the lamp tube, making disassembly and reassembly inconvenient when changing the beam adjustment range or cleaning the convex lens. Therefore, those skilled in the art have proposed a laser light with beam size adjustment functionality to address the problems mentioned in the background. Utility Model Content

[0004] The purpose of this invention is to provide a laser light with beam size adjustment function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A laser light with adjustable beam size includes a base, a lamp tube mounted at the bottom of the base, a threaded rod rotatably connected to the bottom of the base, a drive component mounted on the inner bottom surface of the base, the output end of the drive component connected to the top of the threaded rod, a movable plate disposed inside the lamp tube, the outer wall of the movable plate slidingly fitting against the inner wall of the lamp tube, a threaded sleeve mounted on one side of the movable plate, the threaded sleeve being threadedly connected to the threaded rod, a controller mounted inside the base, a lamp holder mounted at the bottom of the movable plate, a laser light detachably mounted at the bottom of the lamp holder, the drive component and the lamp holder being connected to the controller circuitry, two mutually combined semi-circular ring clamping sleeves detachably mounted at the bottom of the lamp tube, the inner wall of the semi-circular ring clamping sleeves being provided with clamping grooves, a convex lens being clamped in the clamping grooves, and a transparent protective cover being detachably mounted at the bottom of the two semi-circular ring clamping sleeves.

[0007] As a further improvement of this utility model: the inner walls on both sides of the lamp tube are provided with sliding grooves, and the outer walls on both sides of the movable plate are provided with sliders, the sliders being slidably connected in the corresponding sliding grooves.

[0008] As a further improvement of this utility model: a bearing sleeve is installed on the inner wall of the lower side of the lamp tube, and the bottom end of the threaded rod is rotatably connected in the bearing sleeve.

[0009] As a further improvement of this utility model: the top end of the semi-circular ring clamping sleeve is equipped with a first external threaded sleeve that mates with the bottom end of the lamp tube, and the bottom end of the semi-circular ring clamping sleeve is equipped with a second external threaded sleeve that mates with the top end of the transparent protective cover.

[0010] As a further improvement of this utility model: an extension plate is provided between the top end of the semi-circular ring clamping sleeve and the first external threaded sleeve, and a reinforcing ring is fitted around the periphery of the extension plate, the length of the reinforcing ring being the same as the length of the extension plate.

[0011] As a further improvement of this utility model, the inner wall of the clamping groove is provided with an elastic pad.

[0012] This utility model has the following advantages: The laser lamp adjusts the position of the laser lamp inside the lamp tube through the cooperation of the driving component, threaded rod, threaded sleeve, and movable plate, thereby flexibly adjusting the distance between the laser lamp and the convex lens, and realizing flexible adjustment of the beam size. The convex lens is clamped and installed between two semi-circular ring clamping sleeves. After the two semi-circular ring clamping sleeves are combined, they can be detachably installed at the bottom of the lamp tube, making the disassembly and replacement of the convex lens very convenient. When replacing the convex lens, there is no need to open the lamp tube, making the operation convenient and quick. Attached Figure Description

[0022] Please see Figure 1 The lamp tube 3 has sliding grooves 10 on both inner walls and sliding blocks 11 on both outer walls of the movable plate 5. The sliding blocks 11 are slidably connected in the corresponding sliding grooves 10 to improve the movement stability of the movable plate 5. A bearing sleeve 9 is installed on the lower inner wall of the lamp tube 3. The bottom end of the threaded rod 6 is rotatably connected in the bearing sleeve 9 to improve the rotational stability of the threaded rod 6.

[0023] Example 2: See Figures 1 to 3 Based on Embodiment 1, the top end of the semi-circular ring clamping sleeve 14 is equipped with a first external threaded sleeve 20 that mates with the bottom end of the lamp tube 3, and the bottom end of the semi-circular ring clamping sleeve 14 is equipped with a second external threaded sleeve 21 that mates with the top end of the transparent protective cover 18. An extension plate 19 is provided between the top end of the semi-circular ring clamping sleeve 14 and the first external threaded sleeve 20. A reinforcing ring 22 is fitted around the periphery of the extension plate 19. The length of the reinforcing ring 22 is the same as the length of the extension plate 19.

The laser lamp 13 emits a beam that interacts with the convex lens 17 to produce a refracted beam. The size of the refracted beam is adjusted by adjusting the distance between the convex lens 17 and the laser lamp 13. The transparent protective cover 18 is set in a trumpet shape to accommodate the beam adjustment range.
