This changes the problem that traditional lenses can only have one angle of light distribution, and realizes that the same lens can have multiple beam angles. "The utility model lens does not consider further improving the particle structure and combining it with focal length adjustment to reduce the glare value. Utility Model Content

[0023] The following describes the implementation of the present invention through specific embodiments. People familiar with this technology can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0024] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for understanding and reading by those familiar with this technology, and are not used to limit the conditions for implementation of the present invention. Therefore, they have no substantial technical significance.

Changes or adjustments in their relative relationships should also be considered as the scope of implementation of the present invention without substantially changing the technical content.

[0025] like Figures 1-8As shown, the present invention provides an embodiment of an anti-glare lens for industrial and mining lamps, comprising a base plate 200 disposed on a lamp radiator 100, an adjustment mirror plate 300 movably disposed on the lamp radiator 100, and a plurality of lighting beads 400 disposed on the surface of the base plate. The adjustment mirror plate 300 is disposed above the base plate 200, so that the light incident surface of the adjustment mirror plate 300 is opposite to the lighting beads 400, thereby facilitating the light emitted by the lighting beads 400 to enter the light incident surface of the adjustment mirror plate 300. The lighting beads 400 are distributed in a plurality of circular arrays from the center point of the base plate 200 from the inside out, and the lighting beads 400 are preferably LED lamps. The adjustment mirror plate 300 is preferably rotatably disposed on the lamp radiator 100. By horizontally rotating the adjustment mirror plate 300, the adjustment mirror plate 300 can be moved axially, thereby adjusting the beam angle by moving away from or closer to the lighting beads 400 to achieve the purpose of adjusting the brightness of the light. The light-emitting surface of the adjustable mirror plate 300 is provided with a plurality of independent convex lenses 310. The light-entering surface of the adjustable mirror plate 300 is provided with a plurality of annular light-transmitting grooves 320 for accommodating lighting beads. Each annular light-transmitting groove 320 corresponds to a lighting bead 400. The lighting bead 400 passes through the annular light-transmitting grooves 320 and corresponds one-to-one with the convex lenses 310. The adjustable mirror plate 300 is preferably made of PC.

[0026] During use, when bright light is required, there's no need to rotate the adjustment mirror plate 100. Light emitted by the illuminating lamp beads 400 travels along the annular light-transmitting groove 320 and enters the corresponding convex lens 310. The convex lens 310 effectively reduces glare. Compared to the prior art's UGR (Ultra Glare Regulator) of 25.5, the present invention effectively reduces the UGR to 23.8, improving lighting comfort in bright light environments. When dimming is required, the adjustment mirror plate 100 is rotated away from the base plate 200 to adjust the beam angle. Due to the distance between the adjustment mirror plate 100 and the base plate 200, some light traveling between them is prevented from exiting the convex lens 310, thereby reducing light brightness. Compared to the prior art's UGR (Ultra Glare Regulator) of 26.2, the present invention effectively reduces the UGR to 24.3, improving lighting comfort in dim light environments.

[0027] In one embodiment, if Figure 4As shown, the substrate 200 is provided with a number of fan-shaped lighting areas 210, and each lighting area 210 is circumferentially distributed around the axis of the substrate 200. The lighting beads 400 are distributed outward along the radius from the center of the lighting area 210 to form multiple circular arrays, and the density of the lighting beads 400 gradually increases from the center to the periphery, forming a gradient density distribution. Through this gradient density distribution of the lighting beads 400, the utilization efficiency of light can be optimized according to lighting needs, ensuring that the light covers the area that needs to be illuminated. At the same time, the sparser lamp beads in the central area can reduce direct glare, and the peripheral area has more lamp beads, which can provide sufficient lighting without generating strong glare. In addition, the larger number of lighting beads in the peripheral area may help disperse heat, thereby improving the heat dissipation efficiency and durability of the lamp. It should be noted that it can be applied to various lighting scenarios, such as indoor lighting, outdoor lighting, stage lighting, etc., and the distribution and number of lamp beads can be adjusted according to different application requirements.

[0028] Furthermore, the light-emitting surface of the adjustable mirror plate 300 is provided with a plurality of sector-shaped areas corresponding to the illumination areas 210. The arrangement of the convex lenses 310 within these sector-shaped areas corresponds to the arrangement of the illumination lamp beads 400. When the adjustable mirror plate 300 is in contact with the substrate 200, the axis lines of the convex lenses 310 and the illumination lamp beads 400 coincide. When the adjustable mirror plate 300 is rotated by the central angle corresponding to the illumination areas 210 and the adjustable mirror plate 300 is moved away from the substrate 200 to reach a predetermined position, the axis lines of the convex lenses 310 and the illumination lamp beads 400 remain aligned. It should be noted that the rotation angle of the adjustable mirror plate 300 is preferably, but not limited to, 24°, and the rotation angle can also be 20° or 30°.

[0029] When in use, when it is necessary to use in a low-light environment, the adjustment mirror plate 300 is rotated horizontally by 24° so that the lenses on the original fan-shaped area of ​​the adjustment mirror plate 300 correspond one-to-one with the lighting lamp beads 400 in the lighting area adjacent to the original lighting area 210, and the axis lines coincide.

[0030] In one embodiment, if Figure 5 As shown, the root of the convex lens 310 is provided with an anti-glare groove 500 to reduce some glare. When light is emitted from the convex lens 310, under the action of the anti-glare groove 500, part of the light emitted from the lighting lamp bead 400 can be blocked to reduce glare.

[0031] Furthermore, the cross section of the anti-glare groove 500 is V-shaped, and the V-shaped groove can guide part of the light to propagate along both sides of the groove, change the propagation direction of the light, make the light more dispersed and soft, and reduce glare.

[0032] The utility model also provides a mining lamp, which is made of the above-mentioned mining anti-glare lens, so that the mining lamp can effectively reduce glare in weak light or strong light use environment.

[0033] In summary, the present invention employs an annular light-transmitting groove on the light-entering surface of the adjustable mirror plate and multiple independent convex lenses on the light-emitting surface. These convex lenses correspond to the arrangement of the lighting beads, ensuring a one-to-one correspondence between the convex lenses and the lighting beads. When light from the lighting beads enters the convex lenses through the annular light-transmitting groove, stray light generation is effectively reduced, thereby reducing glare. Furthermore, when used in low-light environments, horizontal rotation of the adjustable mirror plate creates a certain distance between the adjustable mirror plate and the lighting beads, effectively reducing both brightness and glare.

[0034] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed in the present invention are intended to be covered by the claims of the present invention.
