Description

Technical Field

[0001] The present disclosure relates to the technical field of lighting, and in particular to a high-altitude line lamp with a narrow light beam. Background Art

[0002] Line lights are mainly installed on the top of the space or on the wall. Line lights are used to illuminate the entire dim space. The inner cavity of traditional line lights lacks long strips of reflectors, which limits the length of the light strip, resulting in a small range of illumination for a single line light beam, which is not suitable for larger spaces. The existing line lights have a beam angle of 120°. Although anti-glare prism plates can be used to narrow the angle, the beam angle still cannot meet the lighting needs of high altitudes (above 5m in height). Excessive beam angles result in low illumination on the ground, so the space is less bright.

[0003] To this end, the patent with patent publication number CN 218819938U proposes a polarized line lamp, including a linear lamp body, a reflector, a light strip and a shading plate; a groove is arranged inside the lamp body, the groove is arranged in the front-to-back direction, the reflector is installed on the left side wall of the groove, the reflector is in a long strip shape, the light strip and the shading plate are both installed on the right side wall of the groove, and the shading plate is located above the light strip.

[0004] However, the polarized line light in the above patent has the following problems:

[0005] Although the polarized line lamp in the above patent solves the problem that the traditional line lamp has a small irradiation range due to the limited length of the light bar, the light source is installed on the side wall of the lamp body, and the light is reflected by the concave mirror to the ceiling or wall. Therefore, when it is installed in a high space, the illumination on the ground is low and the brightness of the space is low. Utility Model Content

[0035] See also Figures 1 to 8 In order to better understand the technical solution and beneficial effects of the present invention, the narrow beam high-altitude line light 10 of the present invention is further described in detail below in combination with specific embodiments:

[0036] A high-altitude line light 10 with a narrow beam of an embodiment includes a shell 100 and a light source component 200, wherein the light source component 200 is arranged on the shell 100. The high-altitude line light 10 with a narrow beam of an embodiment also includes: a dimming component 300, wherein the dimming component 300 includes a dimming lens 310 and a plurality of dimming tooth groups 320, wherein the dimming lens 310 is arranged on the shell 100, and the light incident surface of the dimming lens 310 is arranged toward the light source component 200, and each dimming tooth group 320 includes a plurality of dimming racks 321, and each dimming rack 321 is arranged on the light emitting surface of the dimming lens 310.

[0037] In this embodiment, a plurality of dimming tooth groups 320 are arranged on the light-emitting surface of the dimming lens 310, and each dimming tooth group 320 is provided with a plurality of dimming racks 321. The dimming racks 321 can narrow the light of the light source 200 when it is irradiated on the dimming racks 321, that is, the beam angle of the light emitted by the dimming lens 310 is reduced to form a narrow light beam, and the light emission of the narrow light beam can improve the ground illumination and the brightness of the space when the linear lamp is installed at high altitude.

[0038] like Figure 2 As shown, in one embodiment, there are two dimming tooth groups 320, and the two dimming tooth groups 320 are symmetrically arranged along the center point of the light-emitting surface of the dimming lens 310. It can be understood that the symmetrically arranged dimming tooth groups 320 narrow the light on both sides of the beam angle toward the center of the dimming lens 310, that is, the beam angle of the light source 200 is narrowed, thereby improving the ground illumination and the brightness of the space.

[0039] like Figure 2 As shown, in one embodiment, there are a first dimming gear group 320 and a second dimming gear group 320, the first dimming gear group 320 includes a plurality of first dimming racks 321, the second dimming gear group 320 includes a plurality of second dimming racks 321, the plurality of first dimming racks 321 are arranged along the center point of the light-emitting surface of the dimming lens 310 to one side edge of the light-emitting surface of the dimming lens 310, and the plurality of second dimming racks 321 are arranged along the center point of the light-emitting surface of the dimming lens 310 to the other side edge of the light-emitting surface of the dimming lens 310. It can be understood that each dimming rack 321 is an independent lens, and when the light of the light source 200 passes through the dimming rack 321, the light path is refracted, so as to realize the function of adjusting the beam angle of the light source 200.

[0040] like Figure 2 and Figure 6 As shown, in one embodiment, the tooth surface heights of the first dimming racks 321 gradually increase along one side edge of the light emitting surface of the dimming lens 310, and the tooth surface heights of the second dimming racks 321 gradually increase along the other side edge of the light emitting surface of the dimming lens 310.

[0041] In one embodiment, the tip of the teeth of the first dimming rack 321 is arranged toward the center of the light exit surface of the dimming lens 310, and the tip of the teeth of the second dimming rack 321 is arranged toward the center of the light exit surface of the dimming lens 310. It can be understood that the tooth tips are arranged toward the center of the dimming lens 310, so that the refraction angle of the light path passing through the outer side of the dimming rack 321 is greater than the light passing through the inner side of the dimming rack 321.

[0042] Furthermore, in a dimming tooth group 320, the tooth surface height of the dimming rack 321 gradually increases along one side of the dimming lens 310, and the light emission angle of the light from the light source 200 gradually increases along one side of the dimming lens 310. It can be understood that the larger the light emission angle of the light from the light source 200, the higher the tooth surface height of the dimming rack 321 through which the light path passes, and therefore the greater the refraction angle of the light when passing through the dimming rack 321, thereby achieving the effect of adjusting the beam angle of the light source 200 and narrowing the beam angle of the light source.

[0043] It should be noted that, since the incident angle of the light emitted by the light-emitting component to the edge will gradually increase, the tooth surface height of the dimming rack 321 is adjusted to adapt to the dimming requirements of the gradually increasing incident angle, that is, the light of the light source 200 can be narrowed to between 20° and 45° after passing through the dimming lens 310, but is not limited to 20° to 45°. The narrowing of the beam angle will also change according to the distance setting between the light source 200 and the dimming lens 310.

[0044] Further, in one embodiment, the beam angle of the narrow beam high altitude line light is 20.9°.

[0045] like Figure 3 As shown, in one embodiment, the tooth surfaces of a plurality of first dimming racks 321 have the same height, and the tooth surfaces of a plurality of second dimming racks 321 have the same height.

[0046] In one embodiment, the tip of the first dimming rack 321 is disposed opposite to the center of the light emitting surface of the dimming lens 310 , and the tip of the second dimming rack 321 is disposed opposite to the center of the light emitting surface of the dimming lens 310 .

[0047] It should be noted that the tooth surface height of the dimming rack 321 of the dimming tooth group 320 is consistent, and the light output angle of the light from the light source 200 gradually increases along one side of the dimming lens 310, so that the beam angle of the light source 200 can be adjusted to meet the beam angle adjustment requirements with a narrower range.

[0048] Furthermore, the dimming requirements can be adapted by adjusting the tooth surface height of the dimming rack 321, that is, the beam angle of the light source 200 can be narrowed to between 45° and 60° after passing through the dimming lens 310, but is not limited to 45° to 60°. The narrowing of the beam angle will also change according to the distance setting between the light source 200 and the dimming lens 310.

[0049] like Figure 5As shown, in one embodiment, the light source 200 includes a mounting plate 210 and a plurality of light-emitting elements 220, one side of the mounting plate 210 is fixedly arranged on the housing 100, and the plurality of light-emitting elements 220 are fixedly arranged on the other side of the mounting plate 210. It can be understood that the plurality of light-emitting elements 220 form a continuous light source, so that the light source of the linear light has no granularity, thereby improving visual comfort.

[0050] Furthermore, in this embodiment, the mounting plate 210 is fixedly connected to the housing 100 by screws.

[0051] like Figure 1 and Figure 4 As shown, in one embodiment, the housing 100 is provided with a first clamping member 130 and a second clamping member 140, the first clamping member 130 is provided with a first clamping groove 1301, and the second clamping member 140 is provided with a second clamping groove 1401. The high-altitude line light 10 with a narrow beam further includes a first reflective paper 400 and a second reflective paper 500, one end of the first reflective paper 400 is clamped with the first clamping groove 1301, and the other end of the first reflective paper 400 is fixedly connected to the light source 200; one end of the second reflective paper 500 is clamped with the second clamping groove 1401, and the other end of the second reflective paper 500 is fixedly connected to the light source 200. It can be understood that the light of a large angle is reflected to the dimming lens 310 by the first reflective paper 400 and the second reflective paper 500, thereby improving the light effect of the high-altitude line light 10 with a narrow beam.

[0052] Specifically, in this embodiment, the optical efficiency of the narrow beam high-altitude line light 10 is 85%, and the overall light efficiency reaches 121.9 lm / W.

[0053] like Figure 2 and Figure 4 As shown, in one embodiment, the housing 100 is formed with a first clamping block 110 and a second clamping block 120, and the light incident surface of the dimming lens 310 is provided with a first limit buckle 311 and a second limit buckle 312, the first limit buckle 311 abuts against the first clamping block 110, and the other surface of the first clamping block 110 abuts against the light incident surface of the dimming lens 310, the second limit buckle 312 abuts against the second clamping block 120, and the other surface of the second clamping block 120 abuts against the light incident surface of the dimming lens 310. It can be understood that, through the abutment of the first limit buckle 311 with the first clamping block 110 and the abutment of the second limit buckle 312 with the second clamping block 120, the first clamping block 110 and the second clamping block 120 are fixedly abutted against the light incident surface of the dimming lens 310, that is, the dimming lens 310 is fixed on the housing 100.

[0054] like Figure 2 As shown, in one embodiment, the dimming lens 310 and the plurality of dimming racks 321 are an integrally extruded structure.

[0055] It should be noted that the extruded lens has good continuity, and the length can reach more than 20m without breakpoints. Therefore, the length of the dimming lens 310 can be designed to be longer, so that the narrow beam high-altitude line light 10 has a wider irradiation range, which is particularly suitable for large spaces.

[0056] Furthermore, the dimming component 300 is made of a lightly frosted material, that is, when the dimming lens 310 is in use, the light emitted by the light source 200 is scattered by the frosted layer, making the light spot more uniform, thereby achieving an improved lighting effect and making the narrow beam high-altitude line lamp 10 emit light softer and more uniform.

[0057] Compared with the prior art, the present invention has at least the following advantages:

[0058] By arranging a plurality of dimming tooth groups on the light-emitting surface of the dimming lens, and each dimming tooth group is provided with a plurality of dimming racks, the dimming racks can narrow the light of the light source when irradiating the dimming racks, that is, the beam angle of the light emitted by the dimming lens is reduced to form a narrow light beam, and the light output of the narrow light beam can improve the ground illumination and the brightness of the space when the linear lamp is installed at high altitude.

[0059] The above-mentioned embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the disclosed patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the disclosed patent shall be subject to the attached claims.
