Description

The present invention has a lighting device inside the edge of a rectangular or circular box-shaped picture frame, and illuminates an object to be illuminated (hereinafter referred to as the object to be illuminated) such as a drawing, photograph, document or workpiece, The present invention relates to an apparatus and a system for a photo frame, a display board, etc. (hereinafter referred to as a frame).

There is a display device that prints a photograph or a transparent resin plate in a semi-transparent state by a special method and illuminates it with a so-called backlight light source from the back side. Front-light devices such as picture frames and photo stands that display the actual product as it is are being developed and are becoming popular.

The present invention provides a decorative body that shines on the front side edge of a picture frame that can illuminate an illuminated body mounted in the casing with a light source provided along the hollow interior of the outer peripheral wall surface of the casing.

Problems that the device tries to solve

Illuminated frames such as those described above tend to be less effective in a brightly lit room unless the illumination intensity is increased further, and the illumination of the illuminated object is inconspicuous. It is not desirable to simply increase the illuminance of the light source in the same frame, which causes enlargement of the lighting device and increase in power consumption, and it is bright that the lighting function can be promoted as a product while using the minimum light source necessary for the intended use condition as much as possible. Required in the environment.

Means for solving the problem

The illuminated frame of the present invention has an object to be illuminated in its box-shaped housing, and a light source is stored on the outer wall side of the space provided on the inner side of the frame edge around the frame, and the frame frame edge outside in the vicinity. An attempt is made to solve the above-mentioned problem by appropriately forming a hole through which this light leaks on the front side. The light source is a linear light-emitting body such as a fluorescent tube or a cold cathode fluorescent lamp (CCFL) or a light-emitting diode (LED) arranged appropriately on a plurality of straight lines, provided inside one or more edges of the frame. The light (principal axis light) emitted radially from the light source directly irradiates the illuminated object, and at the same time, the light that does not reach directly is provided so as to be opposed to each other inside the edge of the frame and the bottom surface facing each other. It is reflected by a pair of reflecting surfaces and leaks from the pores on the front side of the frame.

Effect of device

According to the present invention, the light from the illumination light source inside the frame leaks from the pores at the edge on the front side of the frame at a relatively high illuminance before the light diffuses. This makes it possible to obtain a sufficiently bright light spot that is not defeated by the external environment, and even if the frame is not noticeable because the illuminance is reduced due to diffusion of the screen of the illuminated object away from the light source, the frame edge is well-sighted and illuminated The effect of strongly appealing the existence of is obtained. In addition, various decoration effects can be obtained by changing the color of the light source, making the pores into various shapes such as a circle and a star, and providing beads and light-transmitting ornaments in the optical path. With the present invention, a frame that can easily illuminate drawings, photos, documents, and works can be produced more beautifully, giving people peace of mind and opening up new product fields.

Hereinafter, the present invention will be described with reference to application examples of FIGS. FIG. 1 is a schematic perspective view of the structure of a rectangular frame with illumination as a typical example of the device according to the present invention, and FIG. 2 is a sectional view taken along line XX in FIG. The structure of this apparatus is mainly the main structure (1) of the illuminated frame case, the frame side (2), the transparent plate (3) at the upper center of the frame case, and the main structure of the bottom (6) of the case. Illuminated light source (4) provided on the inner surface of the frame edge (2), a pair of reflecting surfaces (7) and pores (8) provided in the vicinity, illuminated objects such as drawings and photographs (5) ) Etc.

The Y-Y line in FIG. 1 indicates a generally longitudinal direction perpendicular to the paper surface of the casing of the frame body (1), and the light source (4) installed in the frame edge (2) is in the form of a fluorescent tube or When it can be regarded as a CCFL equilinear light source, its longitudinal direction is set in a direction parallel to this, and when a plurality of LEDs are arranged as appropriate, it is appropriately mounted on a parallel straight line. Each arrangement | positioning state is shown with a broken line in the left side edge part and right side edge part of FIG.

In the case where the left side of the side cross-sectional view of FIG. 2 is a non-light-transmitting frame edge (2), a pair of light reflected on the surface of the inner linear light source (4) and the bottom surface (6) opposite to the inner surface thereof The reciprocal relationship between the reflective surface (7) and the pores (8) provided in the frame edge (2) in the vicinity thereof is shown. The emitted light has a principal axis direction parallel to the transparent plate (3) or bottom surface (6) of the casing, but the surrounding light is reflected by the pair of reflecting surfaces (7), and a part of the light is reflected. It leaks and diffuses outward through the pores (8). By appropriately providing the position, shape, number, and the like of the pores (8) here, a point light source with brightness close to the illuminance of the light source (4) can be obtained at the edge of the external front. In addition, the pore (8) is provided in the reflective surface (7) of the inner surface of the frame edge (2) at a position that matches the pore (8).

Further, another application example using the principle is shown on the right side of the side sectional view of FIG. When the frame edge portion (2) is composed of decorative edges such as the transparent plate (3) and matte paper (21) as shown in the figure, the latter is provided with pores (8). The reflection surface (7) is provided in the same manner as described above, but the pores (8) are also provided at the same position on the mat paper (21) side.

In order to further enhance the effect of light leaking from the pores (8) described above, an ornament (81) can be provided in the optical path. For example, this is shown by a broken heart pattern in FIG. 1 and a side cross-section in FIG. 2, but mainly transparent resin, glass beads, sheets or films that are transparent to light, circular, heart-shaped, star-shaped, etc. Realized by sticking to the surface of the plate (3). This material can be appropriately colored and colored with a color filter effect on the leaking light, or a material with a high refractive index can be cut to produce a sparkling effect. In addition to the above, the attachment position may be on the upper or lower surface of the pore (8) of the mat paper (21). Also, a unique light diffusion effect can be obtained by applying a light-transmitting curable adhesive to the ornament (81) and applying it to the inside of the pores (81). In addition, when the light source (4) is periodically changed in color, a unique effect can be obtained. Further, if necessary, the light diffusing plate (9) is appropriately used in front of the light main axis in the vicinity of the light source (4) as shown in FIG. It is also possible to adjust the balance with the light leaking from the hole (8). The illuminated frame is applicable not only to the rectangular shape illustrated in FIGS. 1 and 2 but also to other shapes such as a circle (not shown), and the illuminated object (5) Not only the front light system, which is illuminated from the front by a light source (4) with a document or a workpiece, but also the illuminated body (5) is printed on a transparent film and is brought into close contact with the transparent body (3) of the frame. It can also be used as a backlight system that illuminates from the back (not shown), and the clear point light source effect from the pores (8) can be exhibited similarly.
