Description

Lighting fixture equipped with slide film projection function}

The present invention relates to lighting fixtures. When partially illuminated in a house or a business office, the image contained in the slide film can be enlarged and projected on the surface of the wall or ceiling to be illuminated, and the interior decoration and lighting effect can be applied. When it is not, it is possible for the normal partial lighting and the lighting fixture which can adjust the lighting area freely.

Lighting is an important part of the interior, and is widely used to meet the requirements of various places, from diffuse lighting that illuminates a large area as needed to pinpoint lighting that illuminates a small area with high illuminance. Is designed and constructed. Such a conventional lighting fixture is composed of a light source, such as a lamp and a reflector for focusing or diffusing light from the light source according to the lighting use of the lighted portion, and the diffusion or focusing of the light is the shape or reflectance and color of the reflector, Since it is determined and commercialized according to the relative position of the reflector and the light source, the user cannot arbitrarily change its function, and it is manufactured to have only an illumination function. Therefore, once the construction, the user can not change the function arbitrarily, the lighting is monotonous.

In addition, many restaurants, such as restaurants, decorate walls with picture frames or decorate the walls to make the interior unique. Therefore, it is difficult to change the indoor atmosphere due to such economic conditions, because high costs are expended even if the indoor atmosphere is changed according to the seasonal change or if the indoor atmosphere is changed if necessary.

Conventionally, the design of attaching a projection device to a part of a lamp shade of a general lighting fixture has been invented. However, since a general lighting fixture is difficult to focus light from a light source such as a lamp, it is difficult to focus an image to be projected. Brightness and clarity of the image projected from the projection apparatus are drastically degraded by the reflected light emitted from the luminaire, and the brightness of the projected image is not sufficient compared to the surrounding brightness, so it is practically ineffective.

With respect to the above problems, the present invention, when partially lighting the walls or ceiling of the business and house, the user can freely adjust the light diffusion and focusing by a simple operation, not only can easily change the lighting atmosphere, but also interior decoration Instead of installing a special construction on the wall or installing picture frames, it is possible to expand and project a desired picture or picture to a predetermined size, and to have sufficient brightness, and to produce various interior decorations, and to have a function of lighting. It also provides a simple lighting device.

The present invention utilizes the properties of the lens to illuminate the illuminator, a device that enlarges the slides, pictures, photos, and the like on the screen.

1 is a cross-sectional view showing the structure of an image lighting apparatus according to the present invention. As shown in FIG. 1, the present invention comprises a lamp (1) used as a light source and a reflector (2) for focusing the light emitted from the lamp (1) and the reflector (2) integrally or separately from each other. It consists of a light-converging portion 3 which is a mirror surface and shaped into a cylindrical shape and guides the light collected by the reflector 2 in the exit direction. In addition, the projection lens 5 attached to the projection lens barrel (7) and the projection lens (5) in combination with the projection lens (5) in order to project the incident light on the illumination surface, such as walls and ceilings, change the relative position to adjust the focal length A zoom lens 6 attached to the zoom lens barrel 8 and a case 4 for supporting such components and a fixing portion 13 for fixing to the ceiling or wall. Between the light-collecting part 3 and the projection lens 5, a slide inserting hole 33 is provided for enlarging or removing the object to be projected by enlarging a slide film 22 in which a picture or photograph is printed in positive order. do. In addition, the case 4 is provided with a vent 11 for cooling the heat generated from the light source when necessary.

Based on Figure 1 can be described the operation of the present invention as follows. The light emitted from the lamp 1 used as the light source is focused by the reflector 2 and the light collecting part 3 to illuminate the slide film 22 inserted into the insertion hole 33. The light passing through the projection lens 5 attached to the barrel 7 causes the image of the slide film 22 to be enlarged and projected on a wall or the like separated by a predetermined distance. Since the focal length of the lens can be freely changed by the zoom lens 6 configured to change the relative position with the projection lens 5, it is possible to accurately project an image of a desired size at a desired distance.

Since the size and brightness of the projected image can be arbitrarily adjusted according to the type or brightness of the light source, various applications are possible as follows.

Figure 2 shows an example of using the image lighting device according to the present invention as a partial light. In this case, by using the fixing part 13 in a predetermined place such as a ceiling or a wall and then turning on the power, the relative position of the projection lens barrel 7 and the zoom lens barrel 8 is adjusted as shown in FIG. 2. It is possible to change the lighting environment by adjusting the projection area.

3 and 4 show an example of the decoration and lighting by using the image illumination device according to the present invention for the slide film 22 projection. In this case as well, as in the case of FIG. 2, the mounting unit 13 is installed on the ceiling or wall as necessary, and then the slide film 22 into which the desired picture or photo is positively inserted is inserted into the slide insertion hole 33. By adjusting the relative positions of the projection lens barrel (7) and the zoom lens barrel (8) while the power is turned on, it is possible to adjust to the projection screen of the desired size to serve both interior decoration and lighting.

5 shows an example of using the image lighting apparatus according to the present invention for a special purpose such as visual display. In this case, instead of inserting the slide film 22 into the slide insertion hole 33, a clock device 41 having a liquid crystal display window 42 of the size and shape of the slide film is inserted into the slide insertion hole 33 as shown in FIG. By inserting, a visual display shape of any size can be projected on a wall, which is useful for public places where a large visual display device is required.

The image lighting apparatus according to the present invention is capable of changing the lighting atmosphere by diffusing or concentrating the light according to the user's needs after installation, and in the case of a business place such as a restaurant that performs low-illuminance lighting and partially bright lighting. Without installing accessories for interior decoration such as picture frames, you can project your desired pictures and photos on the interior wall with the size you want, and you can change the indoor atmosphere by simply changing the slide film as needed. It can change the environment.

In addition, a part of the show window of the shop is translucent, and the transmissive screen function is provided, so that a predetermined number of advertisements or pictures required by the shop can be projected so that the passers-by can pass through to maximize the advertising effect at low cost. Can be.

In the case of a general house, lighting functions such as light diffusion and focusing can be easily changed as needed, and the indoor atmosphere can be easily changed by projecting desired photographs and pictures on the wall or ceiling as shown in FIG. In the room, as shown in FIG. 4, when a child sleeps, the child or adolescents like fairy tales, such as artwork or a project suitable for projecting on the wall or ceiling can help in emotional development and emotional stability.

In addition, the image lighting apparatus according to the present invention can also be used for special purposes such as visual display as shown in FIG. 5, and in this case, instead of using a large clock, the apparatus can project a visual display shape of arbitrary size onto a wall because it can be used. It can be useful for visual display in dark public places such as spaces.
