2A, in the elevator door light emitting device, only one light source is installed on the cage door CD of the cage which moves up and down along the hoistway, not on the hole door HD provided for each building layer. That is, the light emitting unit 10 including a plurality of light emitting devices 12 is installed on the front surface of the cage door CD.

As shown in FIG. 1B, a plurality of through-holes 22 penetrating each of the door doors HD provided in each building layer forms a transparent portion 20 with a predetermined shape. Since the light emitted from the light emitting portion 10 passes through these through holes 22, it is called a light transmitting portion. Also, a transparent plate 30 including a glass plate is fixed to the front surface of each of the door doors HD. The transparent plate 30 serves to enhance the aesthetics of the door HD and to prevent foreign substances from being caught in the through holes 22 of the transparent portion 20. [

On the other hand, although the entire hall door can be made of a glass plate, in this case, the thickness of the glass should be 1 mm or more in accordance with the Fire Law, and the glass itself is weak to heat and has a problem of heavy weight. For this reason, it is economically advantageous to form the hole door itself as steel and to attach a thin lightweight glass to the surface thereof. When a glass plate is attached, it is preferable to attach an adhesive sheet to the surface of the glass plate so as not to scatter even if the glass is broken. Further, even if the glass breaks and disappears, the diameter of the through hole is preferably 5 mm or less so that the fingers of the passenger are not caught in the through hole of the light transmitting portion.

A light source controller LC for controlling the lighting state of the light emitting element of the light emitting portion is connected to the light emitting portion 10 and a door controller DC for controlling opening and closing of the cage door CD is connected to the light source controller LC . The light source controller LC controls lighting of a plurality of light emitting elements forming the light emitting unit 10 in accordance with the operation of the elevator and the door controller DC is controlled according to the control state of the light source controller LC And controls the operation of the elevator doors (the hall doors and the cage doors).

The number of the through holes 22 constituting the light projecting portion 20 may be arranged in any shape but is preferably formed in a line along both edges of the hall door HD as much as possible, . Since the hole door HD of FIG. 2B is located on the second floor, the number of layers indicated by the through holes 22 is "2 ".

This arrangement of the through holes 22 of the transparent portion 20 is merely an example, and may be arranged as different as necessary. For example, the through holes 22 may be evenly distributed over the whole of the door HD.

In addition, the through holes 22 prevent foreign matter from being trapped in the through holes 22, and the through holes 22 are formed in the heat-resistant transparent member (not shown) so as to prevent flames from being transmitted through the through holes 22 when a fire occurs 24) (see Fig. 4). If necessary, the transparent member 24 may not have heat resistance.

According to the present invention configured as described above, the light source controller LC controls the operating state of the light emitting elements 12 of the light emitting portion 10 according to the alignment state of the cage door CD and the door HD, The arrival floor, the arrival floor, the elevating state or the door opening forecast of the elevator by appropriately passing light through the elevator 20.

Fig. 3 is a view showing a state in which the elevator arrives up to the mid-height of two floors during descent, in which the broken lines represent the cage and the cage door CD, and the solid line represents the hall door.

For example, when the elevator is lowered in the direction of the arrow A and reaches the mid-height of the two layers, the light source controller LC causes only the light emitting elements of the light emitting portion 10 arriving at the downward display arrow portion to light. At this time, as shown in Fig. 3, only the descent indication is lit on the hall door HD. At the same time, the light source controller CD also lights the light emitting elements of the light emitting portion 10 at positions corresponding to the through holes 22 of the light projecting portion 20 arranged in a row on both the door. In this case, as the cage continues to descend, the light passing through the through holes 22 arranged in a row continuously displays the elevator's falling state, so that the passenger waiting in front of the hall door can easily recognize the operation state of the elevator at a glance There will be.

4 is a plan view showing another example of the present invention.

As shown in the figure, a plurality of light receiving elements 42 are disposed between the light emitting elements 12 of the light emitting portion, and a light receiving portion 40 composed of such light receiving elements is further provided on the front surface of the cage door CD. Similarly to the light emitting portion 10, the light receiving portion 40 is also connected to the light source controller LC, and the through holes 22 of the light projecting portion 20 are blocked by an external object, (L) is blocked from being transmitted to the light receiving unit, the door controller (DC) connected to the light source controller LC stops the opening and closing of the elevator door or controls the opening / closing speed. That is, in the present embodiment, it is possible to prevent a safety accident from occurring when a finger is caught between the door (HD) of the door and the door frame.

5 is a plan view showing another embodiment for preventing fingers from being caught.

The light emitted from the second light emitting portion 60 is incident on the translucent portion 20 in the direction of the arrow B in the door frame 50 of the elevator door, Through the through holes (22) of the light receiving portion (40). Similarly, when the through holes 22 of the light projecting unit 20 are blocked by an external object and the light of the second light emitting unit 60 is blocked from being transmitted to the light receiving unit, the door controller DC connected to the light source controller LC, Closing of the elevator door is stopped or the opening / closing speed is controlled, thereby preventing the finger from being caught between the hall door and the door frame.

On the other hand, since the elevator door is to act as a firewall in the event of a fire, the elevator door (hole door, cage door) should not have a hole in principle. In view of this, in the above-described embodiment of the present invention, the through holes opened in the hall door HD are sealed with the heat-resistant transparent member 24 (see FIG. 4). However, It is desirable to install a plate.

FIG. 6 is a view showing such an embodiment, and FIGS. 6A to 6B are rear views of a hall door HD showing a state before and after a fire, respectively.

As shown in the drawing, the fire shield plates 70 for blocking the plurality of through holes 22 constituting the light projecting portion 20 when a fire occurs can be installed inside the hall door HD. Specifically, The flammable plates 70 are fixed by the flammable strap 72 or the bimetallic ring 74 and when a fire occurs the flammable strap 72 is broken or the bimetallic ring 74 is thermally deformed, So that the through holes 22 are blocked while being lowered by gravity.

6A and 6B show an example in which the fire retardant plates 70 are fixed by the inflammable strap 72. When a fire occurs, the fire retardant strap 72 is broken by heat as shown in FIG. 6B, So that the central through holes 22 are cut off and the two side fire escape plates 70 descend along the inclined guides 78 to cut off the through holes 22 located on the side.
