Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Field of Application) The present invention relates to an elevator hall lantern that lights up and displays ascending direction registration, descending direction registration, and arrival at an elevator landing in different colors.

(Prior art) Conventional elevator hall lanterns are shown in Figures 4 and 5.
As shown in the figure, a vertically long box 1 made of a steel plate is embedded in the wall of an elevator hall, and the interior is divided into three stages: top, middle, and bottom.
A face plate 2 made of stainless steel or aluminum is screwed to the front of this box 1, and transparent or semi-transparent acrylic or Three illuminated display boards 3A, 3B, and 3C made of glass, and a green filter 4A and a milky white filter 4 made of acrylic, superimposed on the back surfaces of each of these illuminated display boards 3A, 3B, and 3C, respectively.
B, red filter 4C and each of these filters 4A, 4B
, 4C, incandescent light bulbs 5 as a light source are arranged in three stages, top, middle and bottom, in the box 1, one each facing the back side of the lamps 4C.
A.

It is composed of 5B and 5C.

When the passenger presses the up car call registration button at the elevator hall, the upper incandescent light bulb 5A lights up and the illuminated display board 3A illuminates in green through the green filter 4A to display the up direction registration. Similarly, when a passenger presses the downbound car call registration button, the lower incandescent light bulb 5C lights up and the illuminated display board 3C illuminates in red through the red filter 4C to display the downbound direction registration. When the elevator car approaches and arrives at the floor in question, the middle incandescent light bulb 5B lights up and the illuminated display board 3B illuminates in milky white through the milky white filter 4B to indicate the arrival of the elevator car.

(Problems to be Solved by the Invention) By the way, the conventional elevator hall lantern has the following problems, and improvement thereof has been desired.

In other words, in the conventional elevator hall lantern, the three indications of ascending direction registration, descending direction registration, and arrival are displayed using separate power sources (incandescent bulbs 5A and 5B).

5C) and the corresponding elevator display boards 3A and 3B.

3C and green, milky white, and red filters 4A and 4B.

Since it is done independently from the 4C, there are many parts and assembly is troublesome, and the whole thing is large and requires a large hole to install on the hall wall, making the work troublesome and the installation expensive. It's expensive. Also, as a light source, incandescent bulbs 5A, 5B,
Since 5C is used, the lifespan is short and replacement work is required when the bulb burns out, and the color filter 4A is generated due to the heat generated by the bulb.

There were inconveniences such as deformation of 4B, 4C and the elevator display boards 3A, 3B, and 3C.

The present invention has been made in view of the above circumstances, and has a significantly smaller number of parts, is easier to assemble, can be made smaller as a whole, and can be easily installed on the hall wall, and has a long light source life, with almost no replacement work required. It is an object of the present invention to provide a high-performance elevator hall lantern that generates little heat and eliminates problems such as deformation of illuminated display boards.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object, the present invention provides an elevator hall lantern that uses one light emitting diode (L E D ) having two color light emitting elements as a light source. ) An indicator light and a single piece of illumination that switches to three different colors by lighting one side of the two-color light-emitting elements of this indicator light and lighting both at the same time to indicate ascending direction registration, descending direction registration, and arrival. It is characterized by being composed of a display board.

(Function) With the above configuration, in the elevator hall lantern of the present invention, one side of the two color light emitting elements of one light emitting diode indicator light as a light source is lit, and the light emitting device is turned on depending on the lighted element. For example, the two illuminated display boards illuminate in green or red, and when both elements light up at the same time, they illuminate in an intermediate color resulting from the combination of green and red, thereby registering ascending direction and descending direction. Three displays will be displayed: and arrival. For this reason, all that is required as a light source is one light-emitting diode indicator lamp with two-color light emitting elements and one illuminated display board, which greatly reduces the number of parts, making assembly easier and reducing the overall size. This design makes it easy to install on the hall wall, and since the light source is a light emitting diode indicator, it has a long lifespan and almost eliminates the need for replacement.It also generates less heat, eliminating problems such as deformation of illuminated display boards, etc. It becomes like this.

(Example) An example of the present invention will be described below with reference to FIGS. 1 to 3. In the figure, 11 is a box made of steel plate that is one-third the size of conventional boxes and is buried in the walls of elevator halls.
A small square plate-shaped face plate 12 made of stainless steel or aluminum is attached to the front of the box 11 with screws, etc., and a transparent or translucent acrylic or glass face plate is attached to the central opening of the face plate 12. One illuminated display board 13 is fitted from the back side. A light emitting diode (LED) indicator lamp 15 is provided as a light source in the box 11 so as to face the back side of the illuminated display board 13. This indicator light 15 has two color (green and red) light emitting elements 15a and 15b inside.
It has three terminals 1G and 1R, and by switching the power source, it is possible to light up one side of each of the light emitting elements 15a and 15b or to light up both at the same time.

When a passenger presses the up-car call registration button at the elevator hall, terminal C of the light-emitting diode indicator 15
and G are applied, the green light emitting element 15a lights up, and the illuminated display board 13 illuminates the green light to display the ascending direction registration. Similarly, when a passenger presses the down car call registration button,
The voltage is applied to terminals C and R, causing the red light emitting element 15b to light up, and the illuminated display board 13 illuminates in red to display the descending direction registration. When the elevator car approaches and arrives at the floor in question, voltage is applied to terminals C, G, and R, causing the green and red light emitting elements 15a and 15b to light up simultaneously, resulting in an intermediate color (orange) resulting from the combination of green and red. The illuminated display board 13 illuminates to display the arrival of the car.

In other words, by selecting the lighting conditions for the two-color LED indicator light 15, one illuminated display board 1 is displayed in green for the ascending direction registration display, red for the descending direction registration display, and orange for the car arrival display.
3 will be illuminated and three displays will be displayed.

In the above embodiment, one two-color light emitting diode indicator lamp 15 was used as the light source, but in some cases, two or more light emitting diode indicator lamps may be used.

〔Effect of the invention〕

Since the present invention is configured as described above, one illuminated display board can be cut into three colors by lighting one side of the two color light emitting elements of one light emitting diode indicator lamp as a light source and by lighting both sides at the same time. Instead, three displays can be displayed: ascending direction registration, descending direction registration, and arrival, so the number of parts is significantly reduced and assembly is easy, and the overall size can be reduced, making it easy to install on the hall wall. At the same time, it is possible to obtain a high-performance elevator hall lantern that has a long light source life, requires almost no replacement work, generates little heat, and can eliminate problems such as deformation of illuminated display boards.
