Description

The present invention has a lighting device inside the edge of a box-shaped picture frame, and a picture frame, a photo stand, etc. for illuminating an object to be illuminated (hereinafter called the object to be illuminated) such as a drawing, photograph, document or workpiece disposed on the bottom surface thereof. The present invention relates to a device and a method for a display board (hereinafter referred to as a frame).

In recent years, as a so-called “digital photo frame”, dedicated devices for displaying various digital photographic information obtained by a digital camera on a liquid crystal display device have been commercialized and are spreading. In addition, display devices that print photographs in a translucent state on a film or transparent resin plate using a special method and irradiate with a so-called backlight light source from the back are also popular. Currently, there are few devices on the market, such as picture frames and photo frames, that illuminate and display the actual material such as paper or cloth that has been printed or printed.

Utility model literature

Registered Utility Model No. 3158088

The present invention provides a transparent light source such as glass or acrylic provided on the front part of the frame with the light source provided along the inside of the frame of the frame frame in the state where the object to be illuminated is disposed on the back or in the vicinity of the frame. It consists of a transparent or translucent plate in front of the illumination light source between the inner frame of the illuminated frame that can illuminate integrally by interaction with the reflector, and between the inner surface of the front part of the frame and the detachable back plate provided on the rear of the frame. A frame is provided, and the two can be partitioned and fixed at a predetermined interval to improve the strength of the entire housing, and the radiated light from the light source is diffused, refracted or transmitted to be used for illumination of the object to be illuminated. Provide a lighted picture frame.

Problems that the device tries to solve

In a frame without conventional lighting, the depth of the housing is usually small, and a picture or photographer document is placed between the front part of the frame or a decorative frame close to it and a back plate (back cover) that can be attached to the back. Although it is installed, it is in front of the frame in a frame that requires a depth called the so-called shadow box for storing and displaying three-dimensional objects such as oil paintings, pressed flowers, patchwork or paper crafts, dolls, models and reliefs. In many cases, a grid-like frame is provided between the part and the back plate to maintain an appropriate distance between the two and to arrange the appearance of the inner surface of the housing. When illuminating the various storage exhibits as described above with the built-in lighting device as in the present invention, the frame structure with the depth as described above is required, but it is normal if the illumination light source is in close contact with the inner wall surface of the frame An opaque plate-grid frame made of a wood-based material is provided on the front surface to prevent the passage of light. For this purpose, if a light source for illumination is arranged on the inner surface of the grid-frame frame, a light source device in the exhibition space Is not only exposed and narrowed, but also causes inconvenience that direct light and the device enter the viewer's field of view.

Means for solving the problem

The illuminated frame of the present invention mainly consists of two parts: a box-shaped housing that is formed integrally with the front of the frame, and a back plate that can be attached to and detached from the back of the box-shaped housing. Sometimes they are in close contact with each other, but when the object to be illuminated is housed in the housing, the two are separated and the object to be illuminated can be arranged in the box-shaped housing from the back space from which the back plate is removed. Even a three-dimensional illuminated object as described above can be freely displayed and arranged. A transparent plate such as glass or acrylic is provided on the top surface at the center of the front portion of the frame, and a light source is provided on the outer peripheral wall surface of the box-shaped housing, and both illuminate the object to be illuminated. The light from the light source not only directly irradiates the object to be illuminated, but also radiates well to the center of the face by reflection of the transparent plate, so that a relatively uniform illumination effect is easily obtained. Here, a grid-like frame is provided inside the frame so as to be sandwiched between the front part of the frame and the back plate as described above, and both are partitioned and fixed at a predetermined interval to improve the strength of the entire housing. In order to diffuse, refract, or transmit light and use it to illuminate the object to be illuminated, at least the grid-like frame portion in front of the light source is made of a transparent or translucent plate made of acrylic or glass.

Effect of device

The frame according to the present invention has a simple frame structure so that the depth can be appropriately sized and sufficient strength can be ensured, and an optimum lighting effect can be obtained, so that only ordinary plane drawings, photographs and documents can be used. 3D objects such as oil paintings, pressed flowers, patchwork, or paper craft can be illuminated as objects to be illuminated, and can be illuminated with almost uniform brightness in normal conditions without any special processing. It can also be used for boxes or commercial illuminated advertising boards, exhibition equipment, display boards, etc. In this new product field, the present invention brightly illuminates the things you want to decorate and memories, and gives you more peace of mind and gives you peace of mind. Pioneering can be expected.

Hereinafter, the present invention will be described with reference to the application example of FIG. The upper half of the left XX line in FIG. 1 is a schematic plan view of a lighted frame as a typical example of the apparatus according to the present invention, and the lower half is a YY side sectional view shown on the right side in the drawing. It is a ZZ plane sectional view. The structure of this device is mainly a frame front (1), housing (2), back plate (3), and back plate (3) for attaching / detaching the lighted frame to / from the housing (2). Tool (4), transparent plate (5) attached to the front face (1) of the frame, decorative edge (6), light source (7) attached to the inner wall surface of the casing, lattice-like frame (8), presser It consists of a plate (9) and a body to be illuminated (10).

The back plate (3) can be attached to and detached from the housing (2) with a fastener (4) as shown in the figure, and the housing (2) is usually provided with a hinge having a rotation center on the back end surface of the wall surface of the housing (2). This is done by fastening or removing the back plate (3) of the outer shape that fits inside the wall surface of the body (2). Here, the back plate (3) is fixed at its fixed position mainly in a lattice frame (8), the transparent plate (5), the decorative edge (6), and the press plate (9) inside the housing (2). And the thickness and shape determined by the difference between the thickness dimension in the depth direction composed of the object to be illuminated (10) and the like and the housing dimension (height of the inner wall surface) inside the housing (2). Are set in close contact with each other to obtain sufficient strength. Note that the object to be illuminated (10) is not a drawing or document-like object sandwiched between the presser plate (9) and the back plate (3) as in this example, but a three-dimensional workpiece. In the case of being directly disposed inside the outer casing (2) or the back plate (3), the thickness is not concerned. The frame (8) is formed inside the light source (7) with a lattice structure of a square shape or a cross-girder shape (not shown) as shown in the same plan view, and as described above, the light source (7) The facing front plate is made of a transparent or translucent plate material such as acrylic or glass through which light can pass. By adopting this shape, it is easy to obtain a sufficient compressive strength while acting as a spacer in the axial direction of the casing (2) while being a simple shape, and the inside view of the frame is neatly organized. The light source (7) uses fluorescent lamps, CCFLs (cold cathode fluorescent lamps), and a plurality of LEDs (light emitting diodes). The light transmitting surface of the frame (8) is a milky white acrylic translucent plate or a diffuser. An effective linear light source can be obtained by using a glass plate having a rough surface or an uneven surface. Further, the frame portion that does not face the light source can be made of a transparent or semi-transparent material, and the power supply device, wiring and other parts to be concealed can be accommodated on the back side. In order to configure the frame (8) in a grid pattern, a conventional method used for partitioning a confectionery folding box, etc., is used by combining the strip-shaped plates with appropriate cuts about half the plate width and fitting them together. This is convenient.
