Description

Technical Field

[0001] This utility model relates to the field of lens technology, and in particular to a spiral dot work light lens. Background Technology

[0002] Work lights, especially high-brightness work lights used in industrial, maintenance, and outdoor operations, have stringent requirements for optical performance. Ideal lighting effects need to simultaneously meet the requirements of high luminous efficacy, strong central illuminance, a large, uniform light spot, and the absence of intrusive visual defects. As the core component of the work light optical system, the lens's design directly determines the final optical output quality.

[0003] However, simple lens structures or inefficient stripe designs prevent light from being effectively collected and directed to the target area, resulting in low light energy utilization and insufficient illuminance in the central area to meet the requirements of high-intensity operations. Utility Model Content

[0004] This invention proposes a spiral dot work light lens, which solves the problem in existing technologies where simple lens structures or inefficient stripe designs prevent light from being effectively collected and directed to the target area. The technical solution of this invention is achieved as follows: A spiral dot work light lens, comprising: The lens body has a first light-emitting surface and a second light-emitting surface inside; the first light-emitting surface is a conical surface with circular radial stripes on its surface; the second light-emitting surface is a convex surface with Fermat spiral dots formed on the top of its surface. The mounting base is used to support and mount the lens body; The circular radial stripe structure on the conical surface is used to mix the light spots at the junction of multiple light sources by refraction and reflection, avoiding excessive radial light spot scattering, concentrating the light spots in the effective area and ensuring high light efficiency. The Fermat spiral dot structure is used to homogenize the light and avoid the mottled phenomenon that can easily occur when multiple light sources are combined with regular dots.

[0005] As a preferred technical solution, a mounting ring is fixedly connected to the outer side of the lens body; multiple heat dissipation fins are fixedly connected to the top of the mounting ring along the circumferential direction.

[0006] As a preferred technical solution, a magnetic fixing cylinder is provided around the bottom edge of the mounting ring; the mounting base has an internal mounting groove for inserting the magnetic fixing cylinder; a magnetic column is provided in the mounting groove to achieve magnetic attraction between the magnetic fixing cylinder and the mounting groove.

[0007] As a preferred technical solution, the mounting ring is made of a thermally conductive and insulating material.

[0008] As a preferred technical solution, the heat dissipation fins are provided with heat dissipation grooves; the heat dissipation grooves are arranged in an elongated oval groove structure.

[0009] As a preferred technical solution, the mounting base is provided with a mounting plate along its axial direction for mounting lamps.

[0010] Beneficial effects: The spiral dot work lamp lens of this technical solution significantly improves optical performance through the synergistic effect of the conical radial stripe surface and the Fermat spiral dot surface: the radial stripes efficiently converge the light spot and enhance the central illuminance and luminous efficacy, while the Fermat spiral dot breaks the regular path of light, completely eliminating the regular spots when multiple light sources are combined, and achieving uniform and pure high-quality lighting.

[0014] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0015] A spiral dot work light lens according to an embodiment of the present invention includes: a lens body 1 and a mounting base 4. The lens body 1 has a first light-emitting surface 2 and a second light-emitting surface 3 formed inside. The lens body 1 is fixed to the top of the mounting base 4 by a mounting ring 101. The components work together to achieve efficient light uniformity and light spot control.

[0016] Lens body 1: The interior forms a first light-emitting surface 2 and a second light-emitting surface 3.

[0017] The first light-emitting surface 2 is a conical surface with circular radial stripes 201 on its surface. The circular radial stripe structure on the conical surface effectively converges the light spots at the junction of multiple light sources through a combination of refraction and reflection, avoiding excessive radial divergence of the light spots, and making the light energy more concentrated in the effective illumination area, thus ensuring high light efficiency output.

[0018] The second light-emitting surface 3 is a convex surface, and its top surface is formed with Fermat spiral dots 301. The main function of the Fermat spiral dot structure on the convex surface is to homogenize the light. Its irregular spiral arrangement effectively disrupts the light path and avoids the phenomenon of regular mottled light spots caused by interference or diffraction of regular dots when used with multiple light sources, thus achieving a more uniform and softer light emission effect.

[0019] A mounting ring 101 is fixedly connected to the outer side of the lens body 1. The mounting ring 101 is made of thermally conductive and insulating material, and a heat dissipation fin 5 is fixedly connected to the top of the mounting ring 101. A heat dissipation groove 6 is provided on the heat dissipation fin 5. The heat dissipation groove 6 is set in an elongated oval groove structure. A magnetic fixing cylinder 7 is provided on the periphery of the bottom of the mounting ring 101. An installation groove 8 is provided inside for the magnetic fixing cylinder 7 to be inserted. A magnetic suction post 9 is provided in the installation groove 8. The magnetic fixing cylinder 7 and the installation groove 8 are magnetically attracted to each other, so as to realize the detachable connection between the lens body 1 and the mounting base 4. An installation plate 10 is provided axially on the mounting base 4 for mounting the entire lens to the working lamp body.

[0020] Specifically, the magnetic fixing cylinder 7 and the magnetic suction column 9 in the mounting groove 8 enable quick and reliable installation and removal of the lens body 1 and the mounting base 4. The heat generated during lens operation is conducted through the lens body 1 to the thermally conductive and insulating mounting ring 101, and then transferred via the mounting ring 101 to the top heat dissipation fins 5. The heat dissipation fins 5 and their elongated oval heat dissipation grooves 6 effectively increase the heat dissipation area, promote air circulation, and improve heat dissipation efficiency.

[0021] The following improvements have been made compared to existing technologies: 1. It combines a dual optical structure of conical radial stripes and Fermat spiral dotted surfaces: the conical radial stripes are responsible for converging the light spot, enhancing the central light intensity and luminous efficacy; the Fermat spiral dotted surfaces are responsible for disrupting the light rays, eliminating regular patterns, and achieving uniform light mixing. The two work together to solve the problem of patterning in multi-light source applications while ensuring high luminous efficacy.

[0022] 2. The thermally conductive insulating mounting ring 101 and the heat dissipation fins 5 with elongated oval heat dissipation grooves 6 are directly integrated on the periphery of the lens body. This design shortens the heat conduction path, increases the effective heat dissipation area, improves heat dissipation performance, and helps maintain the long-term stable operation of the lens.

[0023] Beneficial effects achieved: 1. Excellent optical performance It effectively converges light spots to enhance central illuminance and luminous efficacy, while completely eliminating the regular mottled phenomenon caused by multiple light sources, resulting in uniform, pure, and high-quality lighting effects.

[0024] 2. Highly efficient heat dissipation capability The integrated heat dissipation structure effectively conducts and dissipates the heat generated during lens operation, ensuring the long-term reliability and lifespan of the light source and lens body.

[0025] Based on the above innovations, this patent significantly improves optical performance through the synergistic effect of conical radial stripe surface and Fermat spiral dot surface: the radial stripes efficiently converge the light spot and enhance the central illuminance and luminous efficacy, while the Fermat spiral dot breaks the regular path of light, completely eliminating the regular spots when multiple light sources are combined, and achieving uniform and pure high-quality lighting.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
