BEST MODE FOR CARRYING OUT THE INVENTION

(5) In order to make the object, the technical scheme and the advantages of the invention more clear, the invention will be described in detail below with reference to the accompanying drawings and an embodiment. It should be understood that the embodiment described herein are merely exemplary and does not limit the scope of the invention.

(6) As shown in FIGS. 1 and 2, stage light shading device of the utility model includes a light shade 1, light shade adjustment wheels 2 for adjusting the shading pattern of the light shade, a cover plate 4, and an elastic fastening component 5 provided on the cover plate 4 and used for fixing the light shade adjustment wheels 2, in which the cover plate 4 is detachably coupled with the light shade 1.

(7) The cover plate 4 is rotationally coupled with the light shade 1, and a connector 6 coupled with the light shade is provided on the cover plate 4.

(8) The cover plate 4 is connected with the light shade 1 through a rotating shaft 3. The elastic fastening component 5 is an elastic pressing strip. The elastic pressing strip can be a silicone elastic pressing strip, a rubber elastic pressing strip or an elastomer pressing strip, and is good in elasticity and fixes and presses the light shade adjustment wheels tightly with the elasticity. The cover plate 4 rotates around the rotating shaft 3 to realize opening and closing of the cover plate 4. When the cover plate 4 is open, the adjustment wheels 2 are in a free state, and the desired shading pattern can be obtained by operating the adjustment wheels 2. When the cover plate 4 is closed, the pressing strip 5 on the cover plate 4 presses against the adjustment wheels 2 which are fixed by the elasticity of the pressing strip to prevent the adjustment wheels 2 from misoperation and to obtain a stable shading pattern.

(9) As shown in FIG. 3, the light shade 1 includes: a panel 11, a sandwiched plate 12 and a bottom plate 13, which are sequentially provided in a layered relationship through a connecting pole 14 wherein the connecting pole can be a riveting pole or a screw. A first light passing hole 111, a second light passing hole 121 and a third light passing hole 131, which are used for the light beam to pass through, are respectively provided on the panel 11, the sandwiched plate 12 and the bottom plate 13. Four shading blades 15 and a linkage mechanism 16 are provided on the bottom plate 13, and the light shade adjustment wheels 2 drive the shading blades 15 through the linkage mechanism 16 to move and cover the third light passing hole 131 to form the shading pattern. The light beam can form a circular light spot through the first light passing hole, the second light passing hole and the third light passing hole, and the light shade adjustment wheels drive the shading blades to move and cover the third light passing hole on the bottom plate through the linkage mechanism 16 to form the shading pattern so as to achieve the shading of stage light.

(10) Further, a gasket is respectively provided between the panel 11 and the sandwiched plate 12, and the sandwiched plate 12 and the bottom plate 13. The panel, the sandwiched plate and the bottom plate can be assembled to have a compact structure by arranging the gasket.

(11) In the embodiment, the number of the light shade adjustment wheels is eight, and the eight light shade adjustment wheels are divided into four groups which respectively control the four shading blades.

(12) The stage light shading device provided by the embodiment can plug and play, quickly realize the shading of stage light, and is flexible and convenient to operate with obvious stability effect.

(13) The utility model also provides a stage light which includes a light source and the stage light shading device corresponding to the light source. When the light beam emitted by the light source passes through the stage light shading device, the stage light shading device cuts and forms the light beam to achieve a target lighting effect.

(14) The technical features of the above embodiment can be combined at random, and not all possible combinations of the technical features in the above embodiment are described in order to simplify the description. However, the combinations of these technical features should all be deemed within the scope of the specification as long as there is no contradiction among the combinations.

(15) The above embodiment only expresses several implementations of the utility model.
