Description

M320345 VIII. New description: Especially in the technical field of the new type of bulb or illuminator. The utility model relates to a luminescent frame for illuminating an image after a photo frame picture. [Prior Art] Introducing a lighting device into a display panel to illuminate the display J u is, for the field

The technical means used. However, due to the complicated structure and electric shovel, it is often used in large outdoor exhibition panels, and is not suitable for use in small decorative frames such as ordinary cloth, | i π bedroom, and office. How to simplify the lighting structure and achieve the uniform lighting effect is the design purpose of the utility model. [New Content] The purpose of the present invention is to provide a light-emitting frame to overcome the defects of the above conventional structure and to achieve a simple structure and uniform illumination effect. According to the present invention, a light-emitting frame, comprising a frame that engages and holds the edge of the figure, is located behind the frame--the casing, and the flat surface occupied by the picture has a cavity, characterized in that the cavity has A lighting tool for picture backlighting, comprising a power source for driving the lighting tool, the lighting tool comprising a long array of light bulbs longitudinally located in a mounting tube for transmitting light. Wherein the long row of bulbs is located in a tubular diffuser having a diameter that is smaller than the diameter of the mounting tube and located in the mounting tube. Among them, the 5 Hai lighting tool includes a set of light-emitting diodes 5 M320345 " or light bulbs arranged in a line, which are respectively located in a set of holes of a sheet carrier. There is a reflector behind the lighting tool. Wherein, the illumination tool and the driving power source have a photosensitive element or a photodetector for cutting off or turning on the circuit according to ambient light brightness. Wherein, the photo frame or the housing has a column of photovoltaic cells. According to the above description, the reflector may comprise a foil or film, preferably an aluminum sheet or a piece of metallized paper or plastic material. The diffuser and mounting tube can be secured at or near each end with a screw clamp or other convenient fastener. Preferably, the mounting tube and the diffuser are both open and open during use to allow for convection to dissipate heat. The delta power supply can include a battery or a battery. Alternatively, it can be additionally connected to an external power source or a low voltage AC or DC power source. The sensor or photodetector can be used to turn off the circuit in the event of light, so that the device emits light only in dim light or at night to avoid wasting power. > The surface of one or more sides of the frame or housing may be loaded or include one or a column of photovoltaic cells. This setup complements or reduces the need for a battery or external power source. The advantage of the novel is that, through the above structure, the novel achieves a simple structure, uniform illumination, and wide application range. The present invention may be further illustrated by the drawings but is not limited to the drawings. [Embodiment] In Figures 1 and 2, the illuminated frame device shown comprises a frame 6 M320345^ which is made of wood, plastic or other material. The frame can be rectangular 幵y square or other shape. An easel back 2 is attached to a rectangular casing 3 fixed to the rear cymbal of the frame. As shown in Figure 3, the rotatable clamp or ^4 4 removably secures the housing. The housing includes a box 5, /, adapted to insert a set of batteries 6, which are closed by a removable door or cover 7. The screaming body can include two attachments 28 to suspend the phase _ frame to the wall using a hook or nail. A photosensitive element 8, an electric switch 9 and a DC power socket 1 are also placed in the casing. The installation of the picture in the photo frame is shown in Figure 4. An acrylic plastic or glass cover sheet 11 is placed in the frame recess and the picture 12 is placed on the sheet. The housing is closed by -acrylic plastic thin #13纟, which is fastened to the front opening of the housing 3 by screws, clips or other fasteners, and the housing element is fixed via the rotating clip 4. In the right place. _ ^ Figure 5 and Figure 6 show the lighting assembly. Mounted in a thin strip or printed-line board 1 in a linear column of light-emitting diodes 丨5, inserted into a tubular diffuser J yt Ji. · 'Apergizer consists of, for example, opaque or translucent acrylic polymer or paper The gas and light bulb elements are inserted into an outer acrylic plastic garnish 18 which is secured to the bottom plate of the housing by clips 19. The tube and the S are placed in the center of the body and placed axially. A reflective sheet or layer 35 directs the light forward. The sheet may be made of aluminum, other metallic materials or a metalized polymeric material, or paper. This control circuit configuration of the device is shown in Figure 7 from the photosensitive member. The signal from 7 M320345 indicates that the ambient light intensity has dropped to a predetermined value, such as the light at dusk, and a light-emitting component printed circuit board component (PCBA) turns on the light bulb. The circuit system is covered by a tilting cover 27. The battery compartment is shown in Figure 8. The alkaline or rechargeable battery 22 is placed between the connector terminals in a conventional manner and the member is covered by a tilting cover 24 that can be secured by screws or other fasteners. The two cover plates 24 and 27 form a slot for placement in the lighting element, enhancing the reflection of the light that is forwardly penetrating the picture when used. The printed circuit board assembly is shown in FIG. A transistor 25 and microprocessor are mounted on a circuit board by screws (not shown) or other fasteners. Figure 1 shows the LED printed circuit board. The printed circuit board 3 has a plurality of holes, for example four holes, and a white light-emitting diode 31 is mounted in each of the holes. Each of the light-emitting diodes has a resistor 32. The light-emitting diodes emit light on both sides of the printed circuit board strip, providing a strong and economical light source. | Figure 11 shows an embodiment variant. This includes a solar panel of a photovoltaic cell 33 so that the battery is recharged in the event of light. Figure 12 shows the assembly of the LED printed circuit board assembly, the diffuser and the mounting tube, all of which form the lighting elements in a concentric manner. Figure 13 shows a front view and a side view of the array of light emitting diodes, which are placed on each side of a strip of printed circuit board.
