Description

  The present invention relates to a display device using a light emitting diode, and more specifically, a display device that can be attached to a wall surface of an elevator hall where an elevator operates, and a resin composition embedded facing the hall side of the elevator or the like. It relates to the display device used.

  On the wall surface of the elevator hall where the elevator operates, a display device called a normal hall lantern 101 as shown in FIG. 7 is installed on the upper wall 104 or the side wall 105 of the entrance 103 of each elevator 102. In the hall lantern 101, when a hall button 106 installed on the side wall 105 is pressed, one of the elevators 102 installed in each elevator 102 is lit or blinked (hereinafter simply referred to as “lighting”). It is necessary to indicate whether the elevator 102 has arrived at the earliest time and to notify that all the people in the elevator hall 107 are lit. Therefore, when the hall lantern 101 is lit, the portion 109 protruding from the wall surface of the hall lantern 101 is changed to the color of the light source, and the state where the hall lantern 101 is lit not only to the person in front but also to the person on the side Need to be able to confirm.

  Conventionally, as shown in FIGS. 8 and 9, the hall lantern 101 is provided with a lamp 115 for diffusing light as a light source on a bottom surface 114 of a case 113 fitted in a mounting hole 112 formed in a wall surface 111. A structure has been adopted in which a case lid 116 in which a display body 108 made of a protruding resin is incorporated so as to close 113 is fitted. As a result, a predetermined distance is secured between the display body 108 and the lamp 115 to change the color of the entire display body 108 to the color of the lamp 115. However, if the resin used for the display body 108 is a transparent acrylic resin, a person looking from the front knows that the display body 108 is discolored by the lamp 115 and can confirm that the hall lantern 101 is turned on. There is a problem in that it is difficult for a person viewing from the side to see the discoloration of the portion 109 protruding from the wall surface of the display body 108 and to check the lighting of the hall lantern 101.

  In order to solve this problem, the following Patent Document 1 proposes to use a resin having light diffusibility as a material of the display body 108, and secures a distance from the display body 108 using this resin. When the lamp 115 is irradiated, the entire display body 108 can be discolored, and it can be seen that the portion 109 protruding from the wall surface of the display body 108 is discolored even when viewed from the side. The hall lantern 101 can be turned on. Therefore, in order to install the hall lantern 101, it is indispensable to open the mounting hole 112 in the wall surface 111 in order to ensure a predetermined distance between the display body 108 and the lamp 115. In the case of installing 101, there was a problem that the construction cost increased.

  Further, as shown in FIG. 10, in recent years, a thin light-emitting diode 121 is used as a light source in place of the lamp 115, whereby the depth of the hall lantern 101 can be reduced to h2, and the lamp shown in FIG. Compared with the depth h1 in the case of 115, it is possible to reduce the thickness by the amount (h1-h2) changed to the light emitting diode 121. However, if the periphery of the light emitting diode is directly covered with a projection-like display body in order to reduce the depth of the hole lantern, even in the case where the above-mentioned resin having light diffusibility is used, the conventional light emission generally used is used. The diode has high directivity and irradiates forward, so only the front part is discolored, and it can be seen that the display is lit for those looking from the front, but the display is lit for those looking from the side. The problem that it was difficult to understand was not able to be solved. Therefore, even when a light emitting diode is used, it is necessary to open a mounting hole on the wall surface to ensure a predetermined distance from the display body, and there is a limit to reducing the depth of the hole lantern.

  Furthermore, when the resin composition 132 embedded in the hall three-way frame 131 facing the hall 107 side and the entrance / exit 103 side of the elevator 102 is used as the display body 108 to form the hall lantern 101, as shown in FIG. When 115 is used, it is necessary to provide an installation place of the lamp 115 in order to secure a predetermined distance between the display body 108 and the lamp 115, and there is a problem in installing in a narrow place. In addition, since the directivity is high when a conventional emitting diode is used, when the display body 108 is installed, it is understood that the display body 108 is lit to a person looking from the entrance 103 side of the elevator 102 which is the front. There is a problem that it is difficult for a person looking from the side of the hall 107 to see that the display body 108 is lit.
