It is configured to notify the user of the situation.

  However, in the configuration in which the small lens Ar emits point light as described above, since the portion (area) to be optically displayed is extremely small, it is used when the small lens Ar is covered by an obstacle such as a user's finger. There are inconveniences such as a person overlooking the light display.

  In order to eliminate such inconvenience, the foldable mobile phone B shown in FIG. 12 (b) is provided with illumination means configured in the same manner as the backlight of the liquid crystal panel inside the upper housing Ba. The exterior panel Bp made of a translucent material is made to emit light over a wide area by the illuminating means to perform optical display.

Here, the illumination means illuminates the entire area of the light guide plate by attaching a reflection sheet to the rear surface of the light-transmitting light guide plate and internally reflecting light from a light source installed close to the side surface of the light guide plate. The structure of the backlight that is the basis of such illumination means has been disclosed in many documents (see, for example, Patent Document 1).

Hereinafter, the present invention will be described in detail with reference to the drawings illustrating embodiments.
1 to 9 show an example in which an illumination device for an electronic device according to the present invention is applied to a foldable mobile phone which is an embodiment of the electronic device.

  As shown in FIGS. 1 and 2, a foldable mobile phone 1 includes a main body 2 and a lid 3 that is openably and closably connected to the main body 2. The main body 2 includes a transmitter and a key. While an operation unit or the like (not shown) is provided, the lid 3 is provided with a receiver, a liquid crystal display unit or the like (not shown).

  The lid 3 includes an inner case 4 and an outer case 5 assembled to each other, and an exterior panel 6 attached to the outer surface of the outer case 5. An illumination device including the illumination member 10, the LEDs 21 and 22, and the display light reflecting means 30 as components is mounted.

  As shown in FIGS. 3 and 4, the light guide / illumination member 10 constituting the illumination device has a rod shape and a curved portion 10c in the longitudinal direction, and a main body 10A extending in a substantially U shape. The body 10A is composed of box-shaped holders 10H and 10H provided at one end 10a and the other end 10b, and is integrally formed using polycarbonate resin, which is one of translucent materials. Has been.

  Here, it goes without saying that the planar shape of the main body 10 </ b> A having a substantially U shape is formed following the planar shape of the lid 3. In other words, the light guide / illumination member 10 can be formed in accordance with the shape of the mobile phone 1 by providing the curved portion 10c to have a predetermined shape.

  The light guide / illumination member 10 is installed on the outer surface of the outer case 5 in the lid 3, and the outer case 5 has a substantially U shape corresponding to the main body 10 </ b> A of the light guide / illumination member 10 as shown in FIG. 4. Character-shaped mounting grooves 5G and rectangular mounting holes 5H and 5H corresponding to the holders 10H and 10H of the light guide / illuminating member 10 are formed.

  The main body 10A of the light guide / illuminating member 10 is accommodated in the mounting groove 5G of the outer case 5, the holders 10H, 10H of the light guide / illuminating member 10 are fitted into the mounting holes 5H, 5H of the outer case 5, and the light guide is provided. The light guide / illumination member 10 is installed at a predetermined position of the outer case 5 by fitting the pin 10p provided on the main body 10A of the illumination member 10 into the pin hole 5o of the outer case 5.

  Here, the cross section of the main body 10A in the light guide / illuminating member 10 has a shape closed by a continuous curve as shown in FIG. 6, and the display surface 10u of the main body 10A has the outer surface shape of the outer case 5. In addition, the back surface 101 of the main body 10A protrudes downward in a semi-elliptical shape.

  On the other hand, the cross-sectional shape of the mounting groove 5G in the outer case 5 has a loose U shape following the cross-sectional shape of the main body 10A in the light guide / illumination member 10.

  The cross section of the main body 10A in the light guide / illuminating member 10 is not limited to the shape shown in FIG. 6, and various shapes such as an elliptical shape and a round shape can be adopted as a matter of course. It is also possible to have a cross-sectional shape including a partial straight line in the outer shape. In addition, the cross-sectional shape of the mounting groove 5G in the outer case 5 is preferably a shape that follows the cross section of the main body of the light guide / illumination member.

  On the other hand, as shown in FIGS. 7 and 8, the wiring board 7 accommodated and installed inside the lid 3 is mounted with an LED 21 as a first light source and an LED 22 as a second light source, These LEDs 21 and 22 are accommodated in the holders 10H and 10H of the light guide / illuminating member 10 installed in the outer case 5, and their irradiation directions face one end 10a and the other end 10b in the main body 10A, respectively. Yes.

  The LEDs 21 and 22 are for making display light incident on the main body 10A of the light guide / illuminating member 10 and are both laterally emitting (right angle) type LEDs, and are composed of LEDs having different emission colors. ing.

  As shown in FIG. 9, on the back surface 10l of the main body 10A of the light guide / illumination member 10, the fine wrinkles (uneven portions) 10r for irregularly reflecting the display light incident from the LEDs 21 and 22 inside the main body 10A. Is formed over the entire length of the main body 10A.

  On the other hand, the entire outer case 5 is molded from a white colored resin material on the surface of the mounting groove 5G constituting the installation portion of the light guide / illuminating member 10 in the outer case 5, so that this white The display light reflecting means 30 (FIGS. 4 and 9) for reflecting the display light leaked from the rear surface 101 of the light guide / illuminating member 10 by the molding color is configured.

  As the display light reflecting means, besides using the molding color of the upper case 5 as described above, a color with high reflectance is painted or printed on the surface of the mounting groove 5G, or the reflectance of the mounting groove 5G is high. It is possible to adopt various configurations such as sticking a high color sticker.

  The exterior panel 6 attached to the outer surface of the outer case 5 is a member that covers the light guide / illumination member 10 installed in the outer case 5 and constitutes the appearance of the lid 3, and has a translucency such as polycarbonate. In the present embodiment, it is colored milky white.

  In the mobile phone 1 equipped with the illumination device having the above-described configuration, when the LED 21 and the LED 22 are turned on based on an operation such as an incoming call, the first light source from the one end 10a of the main body 10A of the light guide / illuminating member 10 The light from the LED 21 is incident on the main body 10A, and the light from the LED 22 that is the second light source is incident on the main body 10A from the other end 10b of the main body 10A in the light guide / illuminating member 10, and the respective display lights Repeats internal reflection and proceeds inside the main body 10A.

  Here, since the cross section of the main body 10A in the light guide / illuminating member 10 has a shape (see FIG. 6) closed by a continuous curve as described above, the display light incident from the LEDs 21 and 22 is The internal reflection is efficiently repeated inside the light guide / illumination member 10.

  That is, when the light guide / illumination member has a rectangular cross section, the reason is that the display light is concentrated on the corner (corner) of the light guide / illumination member, and the amount of light that leaks to the outside increases. In contrast, the display light travels with a loss due to the above, but there is no corner (corner) in the cross section of the main body 10A of the light guide / illumination member 10 described above. It is transmitted over a long distance by repeating the reflection.

  Further, the planar shape of the main body 10A in the light guide / illuminating member 10 is also substantially U-shaped by providing the curved portion 10c. In other words, the planar shape is a predetermined planar shape without providing a corner portion. For the same reason, the incident display light repeats internal reflection without loss, and is transmitted over a long distance inside the main body 10A.

  Incidentally, the curvature of the curved portion 10c in the main body 10A of the light guide / illuminating member 10 is in consideration of the light transmittance and reflectance of the material constituting the light guide / illuminating member 10, and the wavelength of the emission color of the LEDs 21 and 22 and the like. Needless to say, it is set to a value (curvature) that can transmit display light most efficiently within the range of design conditions restricted by the shape of the housing 3 and the like.

  Here, the light of the LED 21 that has entered from one end 10a of the main body 10A and the light of the LED 22 that has entered from the other end 10b of the main body 10A each reach a portion beyond the curved portion 10c. Then, the entire area of the main body 10A is effectively illuminated by the LED 21.

  Further, the display light from the LEDs 21 and 22 incident on the main body 10A is diffused in the main body 10A because it is diffusely reflected by the embossing (irregular portion) 10r provided on the back surface 101, so that the entire area of the main body 10A is diffused. Is effectively illuminated.

  Furthermore, the display light reflecting means 30 provided in the mounting groove 5G of the outer case 5 reflects the display light leaked from the back surface 101 of the main body 10A, and this display light is incident on the main body 10A again. The brightness of illumination will be greatly improved.

  The illumination of the main body 10A in the light guide / illuminating member 10 is transmitted through the exterior panel 6 attached to the outer case 5, and the operating status (incoming call) of the mobile phone 1 is notified to the user by this display light. Become. Since the exterior panel 6 is colored milky white, the display light is diffused and visually recognized on the exterior panel 6.

  As described above, according to the embodiment of the illumination device according to the present invention, the entire light guide / illumination member 10 extending along the outer shape of the lid 3 in the mobile phone 1 is evenly and brightly provided by the LEDs 21 and 22 as the light sources. As a result, the visibility of the optical display for notifying the user of the operation status of the mobile phone 1 is greatly improved.

  In the embodiment of the illuminating device according to the present invention, the LED 21 and the LED 22 are composed of LEDs having different emission colors, so that the emission color of the LED 21 as the first light source is red, for example, and the second light source When the light emission color of the LED 22 is blue, the curved portion 10c of the main body 10A of the light guide / illuminating member 10 is illuminated with purple display light in which red and blue are mixed, and the length of the main body 10A is long. By changing the display light from red to purple along the direction and further from purple to blue, the visibility of the display light can be improved and the aesthetics can be improved.

  Incidentally, the light emission colors of the LED 21 and the LED 22 are not limited to the above-described red and blue, but it is needless to say that they can be arbitrarily determined based on a desired illumination color.

  In the above-described embodiment, the light guide / illumination member 10 is made of polycarbonate resin. However, the light guide / illumination member is made of various materials having translucency other than the polycarbonate resin, such as acrylic resin. It goes without saying that it can be configured.

  In the above-described embodiment, the exterior panel 6 covering the light guide / illumination member 10 is milky white in order to diffuse the illumination from the light guide / illumination member 10, but may be colored in an arbitrary color. Further, processing such as diamond cutting may be applied to make the illumination stand out.

  In the mobile phone 1 of the above-described embodiment, the light guide / illumination member 10 is covered by the exterior panel 6 attached to the outer case 5, but the mobile phone configured without attaching the exterior panel to the outer case. The light guide / illumination member attached to the outer surface of the outer case may be directly exposed.

Therefore, the visibility of the optical display for notifying the user of the operation status of the cellular phone 1 ″ is greatly improved.

  In addition, the planar shape of the light guide / illuminating member 10 ″ that is substantially J-shaped by the curved portion 10c ″ is formed following the planar shape of the mobile phone 1 ″. In other words, the curved portion 10c ″ is provided. Thus, the light guide / illumination member 10 "can be formed in accordance with the shape of the mobile phone 1".

  Incidentally, in the illumination device of the cellular phone 1 ′ shown in FIG. 10, it is also possible to additionally install the LED 22 ′ facing the other end portion 10b ′ of the light guide / illuminating member 10 ′, as indicated by a chain line in the figure.
