Description

  The present invention relates to a table having an illumination function for irradiating light from, for example, an LED (Light Emitting Diode) light source.

  Conventionally, with respect to tables used in offices, business meeting halls, etc., it has been a problem how to perform hand lighting and overall lighting efficiently, and various techniques have been proposed to solve the problems. For example, Patent Document 1 proposes a table that matches the usage pattern in an office or the like that performs efficient overall illumination. That is, in this table, a lighting fixture that can illuminate substantially the entire surface of the top plate is held above the common area by the illumination instruction means.

  On the other hand, various proposals have been made for backlight devices for illumination. For example, in Patent Document 2, the front end surface of the ultrasonic processing horn is pressed against at least one of the one main surface and the other main surface of the light guide plate substrate to form reflective dots reflecting the processing dots, and for ultrasonic processing The horn is moved relative to at least one of the one main surface and the other main surface with respect to the light guide plate substrate to repeat the formation of the reflective dots, and the one main surface or the other main surface of the light guide plate substrate is repeated. A backlight device having a light guide plate in which reflection dots are formed in at least one predetermined range is disclosed. This backlight device is used for a signboard or the like.

Further, a support member 3a for supporting the flat plate portion 7 is provided in the vicinity of the opening on the inner surface side of the leg portion 3 of the heat radiation portion 3c. The support member 3a is provided on the upper surface side of the heat radiating part 3c, protrudes inward from the inner surface of the leg part 3, and has a predetermined inclination so that the opening gradually increases toward the opening part. It has also been. This is in consideration of heat dissipation efficiency. Furthermore, one end of the light guide plate 6 of the illumination unit 17 is placed on the support surface 3b corresponding to the lower surface of the heat radiating unit 3c.

  In addition, a space for heat dissipation, that is, a heat dissipation portion 4 c is provided in the leg portion 4, and the heat dissipation portion 4 c communicates with an opening 10 provided on the back surface of the leg portion 4. Further, a support member 4a for supporting the flat plate portion 7 is provided in the vicinity of the inner surface side opening of the leg portion 4 of the heat radiating portion 4c. The support member 4a is provided on the upper surface side of the heat radiating portion 4c, protrudes inward from the inner surface of the leg portion 4, and has a contrivance so that the opening gradually increases toward the opening portion with a predetermined inclination. It has also been. This is in consideration of heat dissipation efficiency. Further, the light source 16 and the socket 15 disposed on the side surface of the light guide plate 6 of the illumination unit 17 are placed on the support surface 4b corresponding to the lower surface of the heat radiating unit 4c.

  A power control unit 14 is disposed below the leg 4. The power supply control unit 14 conceptually includes a converter that converts an alternating current supplied from an external power supply into, for example, a direct current suitable for driving the LED elements of the light source 16. The direct current supplied from the power supply control unit 14 is supplied to the LED element of the light source 16 via a wiring (not shown). In this example, since the light control means 9 (see FIG. 8) is further provided, it is possible to set the illuminance in combination with the surrounding environment.

And the L-angle member 2b of the melamine baking coating is affixed on the side surface of the desk surface structure part 2, and the design property and intensity | strength are improved.

  As described above, according to the table having the illumination function according to the embodiment of the present invention, it is possible to enhance the illumination effect, secure a degree of design freedom, and be rich in design. Become. The present invention also includes the following table conceptually.

  That is, the storage chamber 5 that stores the object, the illumination unit 17 that is disposed on the storage chamber 5 and performs illumination using the light source 16 and the light guide plate 6, and a predetermined length from the light guide plate 6 of the illumination unit 17. And a pair of leg portions 3 supporting the desk surface configuration portion 2 at a predetermined height with a three-layer structure including a flat plate portion 7 disposed in parallel with the light guide plate 6 with a gap therebetween. , 4, and the leg portions 3, 4 are support surfaces 3 b, 4 b as first support portions that support the light guide plate 6 that constitutes the illumination portion 17, and a second surface that supports the flat plate portion 7. Provided is a table 1 having an illumination function, characterized in that it includes support portions 3a and 4a as support portions.

  According to this aspect, since the light of the light source 16 is diffused and emitted by the light guide plate 6, the emitted light is irradiated through the flat plate portion 7, and hand illumination is ensured. Further, when the object is stored in the storage chamber 5, the diffused light from the light guide plate 6 is applied to the object, so that a visually stunning presentation is realized. Note that the closer the complementary color relationship between the emission color and the color of the object (artificial grass, etc.) of the storage unit is, the better the visibility is.

  Here, the leg portions 3 and 4 may be provided with openings 8 and 10 for releasing the heat of the illumination portion 17. According to this, since the heat of the light source 16 can be efficiently released, it is possible to contribute to the improvement of the light emission efficiency.

  The flat plate portion 7 may be made of tempered glass. According to this, it becomes possible to visually recognize the object stored in the storage chamber 5, and it is possible to efficiently use the diffused light of the light guide plate 6 of the illumination unit 17 for hand illumination. Furthermore, since the strength is also ensured, the function required for the main body of the desk surface is also ensured.

  Moreover, it is good also as having the light control means 9 for dimming the illumination intensity of the light of the light source 16. FIG. In this case, it is possible to set the illuminance according to the surrounding environment.

  Moreover, the dot trace is formed in the main surface of the light-guide plate 6 which comprises the illumination part 17, It is good also as the light from the light source 16 being diffused by the said dot trace, and becoming illumination light. According to this, since the processed portion is highlighted and visually recognized when the LED of the light source 16 is turned on, the design can be improved. The dot mark may be a logo, a figure, a pattern or the like. Alternatively, the unprocessed portion may be raised.

  In addition, concave or convex line marks may be formed on the main surface of the light guide plate 6 constituting the illumination unit 17, and light from the light source 16 may be diffused by the line marks to become illumination light. In this case, since the processed part is emphasized and visually recognized when the LED of the light source 16 is turned on, the design can be improved.

  Further, by forming a combination of dot marks and concave or convex line marks on one main surface and the other main surface of the light guide plate 6, light is emitted in the vertical direction of the light guide plate 6. When viewed from the desk, the dot marks and line marks are illuminated at the same time as the laying object in the storage room 5, and a lighting effect rich in design is obtained.

  The table having the illumination function according to the embodiment of the present invention has been described above. However, the present invention is not limited to this, and various improvements and modifications can be made without departing from the spirit of the present invention. Of course. For example, as shown in FIG. 10, the storage room of the desk surface forming unit 2 may be used as a drawer unit 20 so as to be slidable for taking in and out objects.
