Description

Technical Field

[0001] The present invention relates to the technical field of spotlights, and more particularly to a linked push-pull light control module and a spotlight using the module. Background Art

[0002] It is really inconvenient if you cannot adjust the aperture pattern when the spotlight is projecting.

[0003] There are two types of spotlights on the market today. One is a structure that cannot adjust the aperture pattern, and the other can adjust the aperture pattern, but the adjustment process is very troublesome and requires manual pushing of the shading sheet. However, in the process of pushing the shading sheet, the shading sheet may shake to both sides of the pushing direction, causing the shading sheet to be inaccurate. At this time, the shading sheet needs to be adjusted manually, which is very inconvenient. Moreover, when manually pushing the shading sheet, in order to ensure the stability of the shading sheet, it is often necessary to clamp the shading sheet very tightly through a vertical force, which also causes certain inconveniences in manually pulling the shading sheet.

[0004] In addition, when adjusting the aperture pattern in the current market, the moving direction of the shading sheet is often adjusted unilaterally, that is, the shading sheet can only be pushed to move inward or outward, but if you want to move the shading sheet to the other side, you need to use your hand to directly act on the shading sheet to assist the shading sheet in moving and resetting, which is very inconvenient. Summary of the invention

[0005] In view of the problems existing in the prior art, the present invention provides a linkage push-pull light control module and a spotlight using the module, which can adjust the aperture pattern of the spotlight through a relatively simple structure and ensure that the light cutter is pushed more conveniently without shaking.

[0029] Reference Figure 1 as well as Figure 2 Embodiment 1 proposes a linkage push-pull light control module, comprising:

[0030] A guide base 100;

[0031] At least one light control unit, the light control unit comprising:

[0032] A guide groove 210 is provided at the guide base 100;

[0033] A linkage inclined top slide bar 221 is slidably disposed in the guide groove 210;

[0034] The light cutting piece 230 is disposed in the guide groove 210 . The light cutting piece 230 is provided with a through hole 231 . The linkage inclined top sliding rod 221 is disposed through the through hole 231 .

[0035] In this embodiment, the assembly is performed as described above. When the linkage inclined top slide bar 221 is slid upward, the linkage inclined top slide bar 221 will drive the light cutting piece 230 to move outward. When the linkage inclined top slide bar 221 is moved downward, the linkage inclined top slide bar 221 will drive the light cutting piece 230 to move inward. This is very convenient, and the guide groove 210 can prevent the light cutting piece 230 from popping out to the horizontal side when the light cutting piece 230 is moved.

[0036] In implementation 2, four light control units are provided and are arranged at equal intervals on the edge of the guide base 100. A pair of light cutting sheets arranged opposite to each other are located on a first horizontal plane, and another pair of light cutting sheets arranged opposite to each other are located on a second horizontal plane. Moreover, the guide groove 210 is arranged on the upper ends of the pair of light cutting sheets, and the vertical height of the guide groove 210 is not less than the sum of the thicknesses of the superimposed light cutting sheets 230.

[0037] In this embodiment, four light control units are provided, so that the light cutting can be controlled from four directions, which is in line with the usage habits of the general public.

[0039] In this embodiment, a limit plate 300 is further provided. By fixing the limit plate 300 on the upper surface of the guide base 100, the light cutting piece 230 can be effectively prevented from popping out in the vertical direction when moving. Preferably, the guide base 100 and the limit plate 300 are both provided with screw holes, and the bolts 400 pass through the screw holes to achieve the fixed connection between the guide base 100 and the limit plate 300. In the implementation of this solution, the guide base 100 and the limit plate 300 are fixed by the bolts 400, and of course, they can also be fixed by other reasonable methods.

[0040] Reference Figure 3 In Embodiment 4, the light control module further comprises a lamp tube 500 , and a slide groove 510 is arranged around the lamp tube 500 , and the linkage inclined top slide rod 221 partially passes through the slide groove 510 .

[0041] In this embodiment, the slide grooves 510 are arranged around the lamp tube 500 , and the number of slide grooves 510 is the same as the number of light control units. This makes it convenient for the user to push the linked inclined top slide bar 221 , thereby controlling the light cutting plate 230 to adjust the light.

[0042] Reference Figure 4 Preferably, the linked inclined top slide rod 221 includes a main body and a push-pull portion 222 , the push-pull portion 222 is integrally formed with the main body, the main body is slidably disposed in the through hole 231 of the guide groove 210 , and the push-pull portion 222 is disposed through the slide groove 510 .

[0043] Preferably, the main body includes a slanted top sliding rod 2211 and a baffle 2212, and the limiting plate 300 is also provided with a slot 310 and a pair of limiting strips 320 correspondingly at each light control unit, the slanted top sliding rod 2211 is arranged through the slot 310, and the baffle 2212 is arranged on the outer side of the limiting strip 320 and abuts against the limiting strip 320. In order to cooperate with the limiting strip, a pair of square grooves 232 are also provided at the edge of the light cutting piece, and a hollow 211 is also provided at the guide groove 210 to facilitate the sliding of the baffle 2212.

[0044] In this embodiment, the inclined top slide rod is set to two forms: a square column and a round column. These two forms are commonly used, but the square column is more stable and practical than the round column. Correspondingly, when the square column is used, the through hole is square, and when the round column is used, the through hole 231 is round.

[0045] Preferably, the guide groove 210 is formed by a pair of bosses 110 located in the guide base 100. This embodiment is formed by providing a pair of bosses 110 in the guide base 100. Of course, a concave platform may also be provided according to actual conditions.

[0046] A spotlight is also proposed, which applies the above-mentioned linked push-pull light control module.
