Colored gobo assembly of rotary-type for lighting apparatus

The present invention relates to a rotary color high auxiliary assembly, and more particularly, a single color gobo having an image pattern related to each other formed on the surface of a rotating disk is installed in a concentric circle form while maintaining an equidistant distance from the center, or image patterns that are different or related to each other The formed plurality of color gobos are installed in a radial form while maintaining an equidistant from the center, so that the images formed in the color gobos on the rotating disc are continuously projected on the screen according to the rotational motion of the rotating disc when applied to a lighting device. It relates to a rotary color high auxiliary assembly that maximizes the advertising effect and further expands the scope of application.

In general, a gobo refers to an opaque shield that is positioned in front of a lamp or camera while mounted on an arm capable of adjusting a stand to block light from a specific part to prevent unintentional light beams from being projected.

In recent years, as special effects are frequently produced in various performances and broadcast programs, a metal plate-shaped gobo with various patterns and image patterns such as moving lights, spotlights, or ellipsoid lights for various special effects It is configured to be detachably mounted on the device (Effect Light) and is widely applied as an auxiliary device of the lighting device.

As described above, when the gobo is mounted on the lighting device and the illumination light is irradiated, the pattern formed on the metal plate is imaged and expressed on the stage background, Horizont, a space that plays the role of the sky, or the stage floor and set. and fantastically directing a broadcast program.

Accordingly, gobos are not only positioned as an indispensable and important existence in the production of performances and broadcast programs, but also as the uses of gobos have diversified, they can be installed on external lighting equipment to illuminate buildings, etc. to make buildings look beautiful or indoors. It is used to decorate the wall beautifully by attaching a gobo to the lighting of the room.

In addition, as shown in the following figure 1, various types of image patterns can be formed in the above-mentioned gobo. As shown in the following figure 2, it is mounted on a lighting device to promote a company or product at night. It is a trend that is being applied to enhance the advertising effect by projecting the image on the floor of the road or the wall of a building.

Figure 2. Example of projecting a commercial image pattern by mounting a gobo on a lighting device

On the other hand, as described above, gobos installed in lighting devices for performances or broadcasting and applied to produce special effects have been mainly used by processing various patterns, figures, or images such as letters or numbers on a metal plate.

As an example of a lighting device using such a gobo, Korean Patent Laid-Open Publication No. 10-2014-0143065 (name: lighting device, hereinafter referred to as 'prior art 1') has been proposed.

The prior art is 'a light source unit emitting light; a gobo wheel unit disposed in front of the light emission direction and arranged in a circle around the rotation axis to adjust the light pattern; It is placed in front of the gobo wheel unit and includes a color wheel unit that changes the color of light so that various lighting effects can be created by manipulating light in various ways.

However, in the prior art, the color is not applied directly to the image pattern formed in the gobo, but the light generated from a separate light source is colored while passing through a single color wheel unit, and the colored light is the image pattern of the gobo. Since it is a method to project a color image while being irradiated to the screen, there is a problem that the color of the image projected on the screen is not clear, and the visual effect is also significantly reduced because various colors cannot be expressed.

In addition, when such a color wheel unit is provided, the structure of the lighting device becomes very complicated, and there is a problem in that it cannot be used in an existing lighting device at all, so that the application range is greatly limited.

Another object of the present invention is to maximize the publicity and advertising effect by continuously projecting images formed on the color gobo on the rotating disc according to the rotating motion of the rotating disc when applied to a lighting device according to the above-described configuration. , to provide a new rotatable color high auxiliary assembly that can further expand the scope of application.

In order to achieve the above object, the present invention is configured such that three rotating disks having a bearing hole that is detachably fitted to the driving shaft of the lighting device in the center are overlapped and attached to each other; A single transparent window in the form of concentric circles is formed on the surface of the rotating disk; The transparent window formed on the rotating disk has a feature in which a color gobo is formed so that color images related to each other are continuously projected on the screen when the lighting device is driven.

In the present invention, the color gobo is formed with the same image pattern on the transparent windows formed on the three overlapping rotating disks; Each of the three primary colors of ink, cyan, magenta, and yellow, is applied to the image pattern formed on the transparent window on each of the above-described rotating disks and allowed to harden. When applied to a lighting device, when light irradiated from a light source passes through a color gobo on the rotating disk, an image of full natural colors according to the combination of the three primary colors is clearly projected on the screen.

In the present invention, instead of being formed in a single concentric circle, the transparent window is formed radially while maintaining an equidistant distance from the center of a plurality of independent transparent windows; Each transparent window formed on the rotating disk has a feature in which a color gobo is formed so that different or related color images are continuously projected on the screen when the lighting device is driven.

When the present invention is applied, when a plurality of color high auxiliary assemblies are formed on the surface of the rotating disc, the same image pattern is formed on the transparent windows on the three rotating discs, and the image pattern formed on each of the transparent windows has the three primary colors of ink. In a state where cyan (cyan), magenta (magenta), and yellow (yellow) are applied and hardened, the three rotating disks are rotated so that each image pattern applied with the three primary colors is exactly matched to each other. Since it is made in the form of overlapping and attached, when applied to a lighting device, when the light irradiated from the light source passes through the color gobo on the rotating disk, the image of the total color according to the combination of the three primary colors is clearly projected on the screen. have.

Accordingly, it is possible to break away from the conventional publicity and advertisement projecting simple phrases such as characters or figures so that images of all natural colors can be projected clearly on the screen, as well as images related to each other by the rotation of the rotating disk are displayed on the screen. As it is projected continuously, it is possible to maximize the promotional and advertising effects, and there is an improved effect that the application range of the color gobo can be further expanded.
