Description

  The present invention relates to an illuminated picture frame, and in particular, for example, a photo, painting, print, printed matter (hereinafter collectively referred to as a picture) is attached with the edge engaged with the frame, and the back of the picture. It relates to a luminaire arranged side by side, i.e. an illuminated picture frame configured to illuminate its image with a light emitter.

  In order to illuminate the displayed picture, it is well known to arrange lighting components in the display panel. However, since such lighting components have complicated structures and circuits, their use is limited to large display panels installed outdoors, and they are used for small decorative picture frames in homes and workplaces. Is not suitable.

  It is an object of the present invention to provide a picture frame with illumination that simplifies the structure of the illumination means and can uniformly illuminate the picture.

  A display device according to the present invention includes a frame for engaging and supporting the edge of the picture, a casing that is located on the back side of the frame and that forms a cavity disposed behind the surface occupied by the picture when the device is used, An illumination means disposed in the cavity and a power supply for the illumination means, the illumination means being configured to illuminate a picture located in the frame from behind, and the illumination means transmits light; It is characterized by comprising a lighting fixture arranged in a longitudinal direction in a mounting tube to be arranged in a long line.

  In a preferred embodiment, the elongated luminaires are arranged in a tubular diffuser, and the diffuser can be arranged in the mounting tube because it has a smaller diameter than the diameter of the mounting tube. .

The illuminating means may comprise a plurality of light emitting diodes (LEDs) or other light bulbs in a linear array attached to each of the plurality of openings in the thin plate support.
The reflector is disposed on the rear side of the illumination means. The reflector may be made of a sheet-like or film-like metal, and is preferably an aluminum plate, a sheet-like metal-coated paper or a plastic material.

  The diffuser and mounting tube may be secured at or adjacent to each end by a threaded clip or other prior art fastener. In a preferred embodiment, the attachment tube and the end of the diffuser are open so that heat can be dissipated by convection during use.

  The power source may consist of one battery or a plurality of batteries arranged in a row. Alternatively or in addition, it may be connected to an external outlet or a low-voltage AC or DC power source.

  The light sensor, that is, the photosensitive detector, can be configured to cut off the circuit in a bright environment such as daytime, so that the display device can be operated only at dusk or at night to save power.

  In other embodiments, one or more outward facing surfaces of the frame, i.e., casing, may incorporate or include a single photovoltaic cell or a plurality of photovoltaic cells arranged in a row. With this configuration, it is possible to compensate for the need for a battery or an external power source, or to reduce such a need.

The present invention will be described below with reference to the drawings, but the description is not intended to limit the invention to the specific embodiments illustrated.
The illuminated picture frame device shown in the drawing comprises a frame 1 made of wood, plastic or other material. The frame 1 may be rectangular, square or other shape. The easel 2 is attached to a rectangular casing 3 fixed to the rear part of the frame 1. The casing 3 is detachably fixed by a rotary fastener as shown in FIG. The casing 3 includes a box 5 configured to accommodate a plurality of batteries 6, and the box 5 is closed by a removable door, that is, a cover 7.

The casing 3 may include two attachments 28 for hanging the frame from the wall by hooks or nails.
An optical sensor 8, an on / off switch 9 and a DC power jack 10 are also provided in the casing 3.

  The process of attaching the picture 12 in the frame 1 is shown in FIG. The cover sheet 11 made of acrylic or glass is disposed in the groove of the frame 1, and the picture 12 is disposed on the cover sheet 11. The casing 3 is closed using an acrylic sheet 13 secured to the front opening of the casing 3 by screws, clips or other fasteners, and the casing assembly is rotated into position by rotating the clip 4. Fixed to.

  5 and 6 show the illumination assembly. A thin strip, or linear array of light emitting diodes (LEDs) 15 attached to a printed circuit board (PCB) 16 is inserted into a tubular diffuser 17 made of, for example, an opaque or translucent acrylic polymer or paper. The The diffuser and lighting assembly is inserted into an outer acrylic mounting tube 18 secured to the floor plate of the casing 3 using a clip 19. The mounting pipe 18 is preferably arranged along the central axis of the casing 3. The reflection sheet, that is, the reflection layer 35 is formed to radiate forward. The reflective layer 35 may be made of aluminum foil, other metal materials, metallized polymer materials, or paper.

  FIG. 7 shows a control circuit of the illuminated picture frame device. The sensor / PCB assembly (PCBA) is configured to switch on the luminaire when the signal from the optical sensor indicates that the intensity of the ambient light is below a predetermined value, such as at dusk. The circuit is surrounded by an inclined cover plate 27.

  The battery compartment is shown in FIG. The alkaline battery and the rechargeable battery 22 are accommodated between the connection terminals by a conventional method, and the assembly is surrounded by an inclined cover plate 24 fixed by screws or other fixing devices.

The two cover plates 24, 27 form a channel that receives the lighting unit in order to better reflect light forward through the picture in use.
The assembly of the PCB is shown in FIG. Transistor 25 and the microprocessor are attached to the circuit board by screws (not shown) or other fasteners.

  FIG. 10 shows an LED / PCB assembly. The PCB 30 has a plurality of openings. For example, as shown in the drawing, white LEDs 31 each having a register 32 are attached to the four openings. The LEDs 31 are arranged to emit light on both sides of the PCB strip, thus providing a robust and economical configuration.
