Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a lighting shield. Background Technology

[0002] Spotlights, downlights, wall washers, and similar lighting fixtures are frequently used in shops, interior decoration, exhibitions, and other venues. To adjust the light pattern or the area of ​​illumination, a light shield is usually installed at the light-emitting end of the fixture to ensure that the light is emitted within a specified range.

[0003] In existing technologies, light shields or condensers are typically one-piece structures that cannot be adjusted. If it is necessary to adjust the size of the light-emitting area, a different model or size of light shield needs to be replaced, which affects the user experience.

[0004] To overcome the above-mentioned defects, the existing technology also uses a horn-shaped light shield at the front end of the lamp tube. The light shield is connected to the lamp tube by a threaded structure. By rotating the light shield, the distance between the horn opening of the light shield and the light-emitting end can be adjusted, thereby adjusting the illumination area.

[0005] However, the shortcomings of the above-mentioned existing technology are: the front and rear position adjustment of the light shield is limited, the range of changes in the light output area that can be adjusted is limited, and since the shape of the light shield is fixed, it cannot realize the function of adjusting the light pattern. Its light output adjustment needs to be improved. Utility Model Content

[0031] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0032] like Figure 1-4 As shown, an embodiment of the present invention provides a lamp shade, including a connecting ring 1 for connecting to the light-emitting end of the lamp and multiple light-shielding plates 2 connected to the outer periphery of the connecting ring 1.

[0033] Multiple light-shielding plates 2 are distributed along the circumference of the connecting ring 1. Each light-shielding plate 2 is connected to the connecting ring 1 through a pivoting mechanism 3. Each light-shielding plate 2 can be adjusted up and down relative to the connecting ring 1.

[0034] The lamp shade provided by this utility model is used to install on the light-emitting end of the lamp to serve the functions of shading and dimming.

[0035] The lamp shade provided in this embodiment includes a connecting ring 1 and multiple light-shielding plates 2. The connecting ring 1 is used to connect to the light-emitting end of the lamp, and the shape of the connecting ring 1 is selected according to the shape of the light-emitting end.

[0036] Multiple light-shielding plates 2 are pivotally mounted on the outer side or periphery of the connecting ring 1 and distributed along the circumference of the connecting ring 1. There is a certain gap between adjacent light-shielding plates 2 to allow each light-shielding plate 2 to be adjusted in position. The shape of the light-shielding plates 2 can be selected as needed, for example, square plates, trapezoidal plates, fan-shaped plates, etc. In the circumference of the connecting ring 1, the shape of the light-shielding plates 2 matches the contour of the connecting ring 1; that is, if the connecting ring 1 is circular, the light-shielding plates 2 are correspondingly arc-shaped; if the connecting ring 1 is square, the light-shielding plates 2 are correspondingly straight.

[0037] Each light-shielding plate 2 is connected to the connecting ring 1 via a pivoting mechanism 3, thereby allowing each light-shielding plate 2 to swing up and down relative to the connecting ring 1. The pivoting mechanism 3 can be a pivot shaft, hinge, etc., and is equipped with damping components, such as damping springs, friction plates, etc., to position the light-shielding plate 2 and fix the adjusted light-shielding plate 2 in the designated position.

[0038] Since each light-shielding plate 2 can be adjusted up and down relative to the connecting ring 1, different light emission patterns can be created. For example, multiple light-shielding plates 2 can be simultaneously tilted towards the centerline of the light emission direction to reduce the light emission pattern and achieve a focusing effect. Alternatively, multiple light-shielding plates 2 can be simultaneously tilted around the light emission direction to increase the light emission pattern and achieve a diffusing effect, thereby expanding the light emission area. Furthermore, if several light-shielding plates 2 are simultaneously tilted towards the centerline of the light emission direction, while the remaining light-shielding plates 2 remain in place or tilt with a smaller amplitude than the aforementioned light-shielding plates 2, the light emission pattern will be restricted to a certain shape, such as a striped light spot, a polygonal light spot, or a near-elliptical light spot.

[0039] If the light-emitting direction is defined as downward, the light-shielding plate 2 can swing upward until it is perpendicular to the wall of the connecting ring 1, roughly horizontally arranged. At this time, the light-shielding plate 2 hardly blocks light at all. The angle at which the light-shielding plate 2 swings downward from the horizontal position can be selected between 0-90°. Multiple light-shielding plates 2 can form a funnel-shaped structure with a gradually widening opening, which plays a role in light diffusion. If a pivot mechanism 3 is used to install the light-shielding plate 2 at the lower end of the connecting ring 1, or a hinge mechanism 3 is used to install the light-shielding plate 2, the angle at which the light-shielding plate 2 swings downward from the horizontal position can reach as much as 135°. It can swing towards the centerline of the light-emitting direction. Multiple light-shielding plates 2 can form a funnel-shaped structure with a gradually narrowing opening, which plays a role in light focusing.

[0040] In summary, the lamp shade provided by this utility model allows each of its shade plates 2 to swing up and down relative to the connecting ring 1, thereby enabling the adjustment of different light emission patterns and allowing for adjustment of the light emission area over a wider range. This makes operation convenient and improves the performance of the product.

[0041] In one embodiment, such as Figure 1-5 As shown, the pivoting mechanism 3 adopts a hinged structure, which includes a fixed base 31 and a connecting arm 32. The fixed base 31 is disposed on the outer circumferential surface of the connecting ring 1. Preferably, the fixed base 31 is integrally formed with the connecting ring 1. One end of the light-shielding plate 2 is connected to one end of the connecting arm 32, and the other end of the connecting arm 32 is connected to the fixed base 31 through a rotating shaft. If necessary, a clamping groove can be provided at one end of the connecting arm 32 to clamp one end of the light-shielding plate 2, and then it can be fixed by a pin.

[0042] In one embodiment, such as Figure 1-4 As shown, the multiple light-shielding plates 2 include at least one light-shielding main plate 21 with a fixed area and / or at least one light-shielding secondary plate 22 with an adjustable area.

[0043] In this embodiment, the structures of the multiple light-shielding plates 2 can be designed differently to meet the needs of light adjustment. Specifically, the multiple light-shielding plates 2 include at least one main light-shielding plate 21 and at least one secondary light-shielding plate 22. The area of ​​the main light-shielding plate 21 remains constant, that is, the main light-shielding plate 21 adopts an integrated structure with a constant surface area. When the main light-shielding plate 21 is adjusted to a certain angle, the light-blocking area of ​​the main light-shielding plate 21 is also determined. The area of ​​the secondary light-shielding plate 22 is adjustable, so that the light-shielding area can be adjusted as needed. The secondary light-shielding plate 22 adopts a split structure, and the two adjacent plates on the left and right sides can be extended or retracted, thereby enabling adjustment of the light-blocking area.

[0044] After adjusting the main light-shielding plate 21 to a certain angle, adjust the secondary light-shielding plate 22 to the required angle. If the gap between the main light-shielding plate 21 and the secondary light-shielding plate 22 is too large, the gap can be reduced or completely covered by adjusting the secondary light-shielding plate 22 so that the two adjacent plates on the left and right can extend or unfold.

[0045] In one embodiment, such as Figure 1-4 As shown, the multiple light-shielding plates 2 include multiple main light-shielding plates 21 and multiple secondary light-shielding plates 22. There is a secondary light-shielding plate 22 between any two adjacent main light-shielding plates 21, and there is a main light-shielding plate 21 between any two adjacent secondary light-shielding plates 22.

[0046] In this embodiment, by configuring a light-shielding sub-plate 22 between each pair of adjacent light-shielding main plates 21, the gap between the two light-shielding main plates 21 and the intermediate light-shielding sub-plate 22 can be adjusted by expanding and contracting the light-shielding sub-plate 22, thereby achieving a better light-diffusing effect.

[0047] In one embodiment, such as Figure 1-5 As shown, the connecting ring 1 is square, and the multiple light-shielding plates 2 include a pair of main light-shielding plates 21 and a pair of secondary light-shielding plates 22.

[0048] In this embodiment, the connecting ring 1 is square to fit a square lamp tube. A pair of light-shielding main plates 21 are mounted on a pair of parallel sides of the connecting ring 1, and a pair of light-shielding secondary plates 22 are mounted on another pair of parallel sides of the connecting ring 1. The pair of light-shielding secondary plates 22 are used to adjust the gap on the corresponding sides.

[0049] In one embodiment, such as Figure 1 and Figure 4 As shown, the light-shielding main board 21 is trapezoidal, and its short side is connected to the pivot mechanism 3, so that when the light-shielding main board 21 is lowered, it can have more area to block light. The light-shielding main board 21 is preferably in the shape of an isosceles trapezoid.

[0050] In one embodiment, such as Figure 1 and Figure 4 As shown, the light-shielding sub-plate 22 includes a sub-plate main plate 221 connected to the pivoting mechanism 3 and a sub-plate swing plate 222 pivotally connected to the sub-plate main plate 221.

[0051] When the secondary board swing plate 222 is in the retracted state, the secondary board swing plate 222 is stacked on the front or back side of the secondary board main board 221.

[0052] When the secondary plate swing plate 222 is in the unfolded state, the secondary plate swing plate 222 extends out from the side of the secondary plate main plate 221.

[0053] In this embodiment, the light-shielding sub-plate 22 includes a sub-plate main plate 221 and a sub-plate swing plate 222. The sub-plate main plate 221 is connected to the pivoting mechanism 3, and the sub-plate swing plate 222 is connected to the sub-plate main plate 221 via a pivot shaft, so that the sub-plate swing plate 222 can swing relative to the sub-plate main plate 221 to achieve the retraction and extension function. Specifically, the end of the sub-plate swing plate 222 facing the pivoting mechanism 3 is connected to the sub-plate main plate 221 via a pivot shaft, and the sub-plate swing plate 222 can swing out or back from one side of the sub-plate main plate 221.

[0054] The secondary board swing plate 222 can be located on the front or back side of the secondary board main board 221. Here, the front side of the secondary board main board 221 refers to the side facing or close to the light output path, and the back side refers to the side facing away from or away from the light output path. Of course, the aforementioned back side can also be referred to as the rear side.

[0055] When the secondary board swing plate 222 is in the retracted state, the secondary board swing plate 222 is stacked on the front or back side of the secondary board main board 221, and the light-blocking area at this time is determined by the area of ​​the secondary board main board 221.

[0056] When the secondary plate swing plate 222 is in the unfolded state, the secondary plate swing plate 222 extends from the side of the secondary plate main plate 221. At this time, the light-blocking area is determined by the area of ​​the secondary plate main plate 221 and the area of ​​the extended secondary plate swing plate 222.

[0057] In one embodiment, such as Figure 3-4 and Figure 6-7 As shown, the light-shielding sub-plate 22 includes two sub-plate swing plates 222, which are arranged on the front and back sides of the sub-plate main plate 221.

[0058] In this embodiment, each set of light-shielding sub-plates 22 is equipped with a sub-plate main plate 221 and two sub-plate swing plates 222. In order to avoid interference between the two sub-plate swing plates 222, the two sub-plate swing plates 222 are arranged on the front and back sides of the sub-plate main plate 221. The two sub-plate swing plates 222 can swing out or swing back from the left and right sides of the sub-plate main plate 221, thereby adjusting the gap on both sides.

[0059] Preferably, the two auxiliary swing plates 222 are arranged symmetrically from left to right, and the two auxiliary swing plates 222 can swing in the same range and in the same way, which is conducive to unified configuration.

[0060] In one embodiment, such as Figure 6 As shown, the secondary plate swing plate 222 is provided with a swing plate recess 2223 for avoiding the pivoting mechanism 3. The secondary plate swing plate 222 can also be designed in the shape of a sickle, which has a swing plate recess 2223 for avoiding the pivoting mechanism 3, specifically avoiding the connecting arm 32 of the pivoting mechanism 3.

[0061] In one embodiment, such as Figure 4 and Figure 6-7 As shown, the sub-board main board 221 is trapezoidal, and the long side of the sub-board main board 221 is connected to the pivot mechanism 3.

[0062] The secondary plate swing plate 222 includes a strip plate 2221 and a fan plate 2222 connected to the strip plate 2221. The outer edge of the strip plate 2221 is flush with the outer edge of the fan plate 2222. One end of the strip plate 2221 extends toward the long side of the secondary plate main plate 221 and is pivotally connected to the secondary plate main plate 221.

[0063] In this embodiment, the secondary main board 221 has a trapezoidal structure, preferably an isosceles trapezoidal structure. The long side of the secondary main board 221 is connected to the pivot mechanism 3, and after the secondary main board 221 swings down, it becomes wider at the top and narrower at the bottom, thereby avoiding the adjacent light-shielding main board 21.

[0064] The secondary swing plate 222 is composed of a strip plate 2221 and a fan-shaped plate 2222. Preferably, the fan-shaped plate 2222 and the strip plate 2221 are integrally formed. The strip plate 2221 is narrower than the fan-shaped plate 2222, and their outer edges are flush, causing the fan-shaped plate 2222 to protrude towards the inner side of the strip plate 2221, thus forming a swing plate recess 2223 at the connection between the fan-shaped plate 2222 and the strip plate 2221. The end of the strip plate 2221 away from the fan-shaped plate 2222 extends towards the long side of the secondary main plate 221 and is connected to the secondary main plate 221 via a pivot shaft. Preferably, one end of the strip plate 2221 is connected to the apex corner region of the secondary main plate 221.

[0065] With this configuration, when the secondary swing plate 222 is retracted, the outer edges of the strip plate 2221 and the fan plate 2222 can be flush with the side edge of the secondary main plate 221, or will not protrude from the side edge of the secondary main plate 221. Since the fan plate 2222 protrudes towards the inside of the strip plate 2221, when the secondary swing plate 222 is extended, the fan plate 2222 can largely remain stacked with the secondary main plate 221 without quickly separating. At the same time, the two secondary swing plates 222 and the secondary main plate 221 form a trapezoidal structure that is narrow at the top and wide at the bottom, to fill the trapezoidal space formed by the two light-shielding main plates 21 on both sides after they are extended, thus achieving a better light-shielding adjustment effect.

[0066] In one embodiment, such as Figure 1-2 and Figure 4 As shown, the connecting ring 1 is equipped with a clamping mechanism 4 for clamping the light-emitting end of the lamp, which is used to fasten the lamp to the light-emitting end. The clamping mechanism 4 can be a clamping pin, a clamping block, etc.

[0067] Preferably, such as Figure 1-2 and Figure 4As shown, the connecting ring 1 has an internal threaded hole. The tightening mechanism 4 includes a knob 41 and a top block 42. The knob 41 has a threaded rod 411, and the top block 42 is pivotally connected to the threaded rod 411. The knob 41 is located on the outside of the connecting ring 1, and the top block 42 is located on the inside of the connecting ring 1. By rotating the knob 41 in both directions, the top block 42 can be adjusted to tighten or loosen from the light-emitting end, which is convenient for operation. Furthermore, the large area of ​​the top block 42 will not damage the light-emitting end.

[0068] As needed, the above technical solutions can be combined to achieve the best technical effect.

[0069] The above are merely the principles and preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several other modifications can be made based on the principles of this utility model, and these modifications should also be considered within the scope of protection of this utility model.
