Description

Stage lamp with animation effect

Technical Field

The invention relates to the field of stage lamps, in particular to a stage lamp with an animation effect.

Background

The animation effect of the patterns of the present stage lamps is generally realized by the rotation of a single pattern of a pattern disc, and cannot form a projection similar to a film projector

Continuous scene changes or the visual effect of continuous motion of certain living things.

The most important principle of a movie is "persistence of vision". Scientific experiments prove that after a certain visual image disappears, human eyes can still make the object image stay on the retina for about 0.1-0.4 seconds. The motion picture film rotates at a constant speed of 24 pictures per second, and a series of static pictures can generate a continuous visual impression due to the action of visual persistence, thereby generating vivid dynamic feeling.

Whether the principle of the movie can be applied to the lamp and the relatively optimal continuous animation effect is achieved is a new direction for the application of the stage lamp.

Disclosure of Invention

An object of an embodiment of the present invention is to provide a stage lamp with an animation effect, which can apply a movie effect to a stage lamp, thereby achieving the animation stage effect.

In order to achieve the purpose, the invention adopts the following technical scheme:

a stage lamp with animation effect comprises a light source, a pattern component and a projection lens, wherein the pattern component is positioned between the light source and the projection lens; the pattern disc is in a single disc shape and is arranged on the stepping motor; the pattern disc is provided with 24 patterns which are uniformly arranged at intervals along the circumferential direction of the pattern disc, the patterns are different postures of the same creature, and any adjacent patterns have continuously-changed postures; when the stepping motor drives the pattern disc to rotate, the 24 patterns sequentially pass through the light through holes, so that each pattern forms continuous animation effect projection under the action of the light source and the projection lens; the size of the light through hole is set to be the size of the coverage area of the light source which can only contain one pattern when the light emitted by the light source passes through the light through hole and is emitted to the pattern disk.

Furthermore, the pattern disc is made of metal.

Specifically, the pattern is a hollow area arranged on the pattern disc.

Furthermore, the pattern disc is made of glass.

Specifically, the pattern is a transparent area arranged on the pattern disc.

Further, the 24 patterns are different from each other.

Further, the 24 patterns are two groups of identical patterns, each group is 12 patterns, and the two groups of patterns are arranged end to end in sequence.

Further, the light source is an LED light source.

Furthermore, the pattern assembly also comprises a flange, and the pattern disc is fixed on a motor shaft of the stepping motor through the flange.

Further, the driving mode of the stepping motor driving the pattern disc to rotate is a rotation-stop switching mode.

The invention has the beneficial effects that: in the scheme, 24 patterns which are uniformly arranged along the circumferential direction of the pattern disc at intervals rotate under the driving of the stepping motor, and then continuous animation effect projection is formed under the action of the light source and the projection lens. Compared with the conventional stage lamp, the stage lamp has the following advantages:

1-multiple patterns of conventional stage light fixture are independent and have no correlation; the patterns in the scheme of the invention are continuous different postures of the same creature;

2-adopting 24 patterns similar to the playing principle of the motion picture film, compared with the non-24 patterns, the animation effect experienced by human eyes is more natural and vivid;

3-the pattern disk is driven by the stepping motor of the technical scheme to adopt a high-frequency rotation-stop switching mode, patterns can be projected to have continuous animation effects only by the driving mode, and the conventional pattern disk rotates all the time, so that only virtual light is formed and animation effects cannot be formed.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the description of the present invention, unless otherwise expressly specified or limited, the terms "connected," "connected," and "fixed" are to be construed broadly, e.g., as meaning permanently connected, removably connected, or integral to one another; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

In the present invention, unless otherwise expressly stated or limited, "above" or "below" a first feature means that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact with each other via another feature therebetween. Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly under and obliquely below the second feature, or simply meaning that the first feature is at a lesser elevation than the second feature.

The stage lamp with animation effect as shown in the attached drawings comprises a light source 1, a pattern component 2 and a projection lens 3, wherein the pattern component 2 is positioned between the light source 1 and the projection lens 3; the pattern assembly 2 comprises a pattern disc 22, a fixed frame 21 and a stepping motor 23, the pattern disc 22 and the stepping motor 23 are fixed between the light source 1 and the projection lens 3 through the fixed frame 21, and the fixed frame 21 is provided with a light through hole 211; the pattern disk 22 is a single disk shape and is installed on the stepping motor 23; 24 patterns 221 which are uniformly arranged at intervals along the circumferential direction of the pattern disc 22 are arranged on the pattern disc 22, the 24 patterns 221 are different postures of the same creature, and any adjacent patterns 221 have continuously-changed postures; when the stepping motor 23 drives the pattern disc 22 to rotate, the 24 patterns 221 sequentially pass through the light through holes 211, so that each pattern 221 forms continuous animation effect projection under the combined action of the light source 1 and the projection lens 3; the size of the light passing hole 211 is set to cover only one pattern 221 when the light emitted from the light source 1 passes through the light passing hole 211 to the pattern disk 22.

When the stepping motor 23 drives the pattern disk 22 to rotate above the light through

holes

211, 24 patterns 221 on the pattern disk 22 sequentially pass through the light through holes 211; when the light emitted by the light source 1 passes through the light-passing hole 211, the 24 patterns 221 positioned above the light-passing hole 211 are projected on the stage one by one, because the 24 patterns 221 are different postures of the same creature, and any adjacent pattern 221 has a continuously changing posture, the continuous switching of different postures of the same creature can be formed, so that the animation effect like a discharge shadow is formed; and because the number of the patterns on the pattern plate 22 is 24, the visual effect generated at this time is the best.

As a preferred embodiment, as shown in fig. 3, the pattern plate 22 is made of metal, in this case, 24 patterns 221 are all hollowed out, the non-pattern area is a metal disc, and the fixing holes 222 in the middle area are used for fixing the pattern plate 22. The light of the light source 1 passes through the hollow pattern 221 region to form a corresponding pattern projection effect.

As a preferred embodiment, as shown in fig. 4, the pattern plate 22 is made of glass, the surface of the pattern plate 22 is covered with a light-shielding layer, in this case, 24 patterns 221 are transparent, and the positioning holes 223 in the middle region are used for positioning when the pattern plate 22 is fixed. When the light of the light source 1 passes through the pattern disk 22, only the transparent pattern 221 region can transmit light, thereby forming a corresponding pattern projection effect.

In a preferred embodiment, the 24 patterns 221 are different from each other, that is, the 24 patterns are 24-part exploded pattern diagrams of a certain continuous state of a living body, and such a state is suitable for representing a non-repetitive motion in daily life.

In another embodiment, the 24 patterns 221 are two identical sets of 12 patterns, each 12 patterns being a 12-point decomposition pattern of a certain biological continuous state, and the other 12 patterns are repeated, and the two sets of patterns are arranged end to end. This condition is suitable for activities that are easily repeated in daily life, such as running, and for limb activities that are actually repeated.

As a preferred embodiment, the light source 1 is an LED light source.

In a preferred embodiment, as shown in fig. 5, the pattern assembly 2 further includes a flange 24, and the pattern plate 22 is fixed to a motor shaft of the stepping motor 23 through the flange 24.

As a preferred embodiment, the stepping motor 23 drives the pattern disk 22 to rotate in a high-frequency stop-and-go switching mode, which has the advantage that only by the high-frequency stop-and-go-stop switching, the effect of continuous animation can be realized; in the conventional manner, the stepping motor 23 drives the pattern disk 22 to rotate all the time, or when a specific pattern 221 needs to be projected, the pattern disk 22 is completely stationary when rotating to the specific pattern 221, and this driving manner cannot form a continuous animation effect of a plurality of patterns 221; meanwhile, even if the pattern disk 22 in the present embodiment is used, when the stepping motor 23 is driven in a conventional manner, i.e., the pattern disk 22 is rotated all the time, virtual light, i.e., a white light effect similar to a very blurred light, is projected, and an animation effect cannot be formed.
