JPH0873133A - Illumination control device in car of elevator - Google Patents

Abstract

PURPOSE: To prolong the life of a fluorescent lamp by dividing a plurality of fluorescent lamps for illumination in a car into two groups, and putting out one group of the fluorescent lamps set by the stop condition of an elevator, whether the elevator is elevated and stopped, or it is brought down and stopped. CONSTITUTION: When a car stops after ascent operation, a contact 1 is closed and a timer T1 is energized, a contact (t1 ) is opened after the lapse of a set time, and hence a first group of fluorescent lamps L1 are put out. Thereafter, when the car is in the running and running preparation state, the contact (t1 ) is closed, and the first group of fluorescent lamps L1 is lighted. Meanwhile, when the car is stopped after descent operation, by close of a contact 5, a timer T2 is energized, a contact (t2 ) is opened after a prescribed time, and a second group of fluorescent lamps L2 are put out. When the car is in the running and running preparation state, the contact (t2 ) is closed, and the second group of fluorescent lamps L2 are lighted.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a car interior lighting control device for an elevator having a plurality of fluorescent lamps as car interior lighting.

[0002]

2. Description of the Related Art In recent years, in order to save energy, an increasing number of elevators have a configuration in which the car interior lighting is turned off when the elevator is stopped. However, if all the lights inside the car are turned off, the inside of the car may be dark when the elevator is restarted, which may give anxiety to passengers. As an example of a solution to this problem, two fluorescent lamps
The one that is divided into groups and has a structure in which one group is turned off
It is disclosed in Japanese Patent No. 173574.

[0003]

In the above-mentioned prior art, since one set of fluorescent lamps is always lit, passengers' anxiety can be eliminated, but the life of the fluorescent lamp is not taken into consideration.

That is, since one set of fluorescent lamps is always turned on, the life is shorter than that of the other set of fluorescent lamps. Generally, in elevator maintenance work, replacement of fluorescent lamps is When one lamp reaches the end of its life, all the fluorescent lamps are replaced, so that there is a problem that the life of the fluorescent lamp is not extended. Further, even if only the fluorescent lamp that has reached the end of its life is replaced, the number of replacement work increases and the burden on the maintenance staff increases. Further, the illuminance of the replaced fluorescent lamp is different from that of the old fluorescent lamp, which causes a feeling of discomfort to passengers.

An object of the present invention is to provide an elevator in-cabin lighting control device that solves the above-mentioned problems, alleviates passengers' anxiety due to the darkness of the inside of the car, and extends the life of the fluorescent lamp. .

[0006]

SUMMARY OF THE INVENTION The above-mentioned object is to provide a plurality of fluorescent lamps as an in-car illumination, and an elevator in-car illumination control device for turning off the in-car illumination when the elevator is at rest. It is divided into two sets, a first extinguishing means for extinguishing one set of the two sets of fluorescent lights when the elevator is stopped, and a second set of the two sets. The fluorescent lamp is provided with the second extinguishing means for extinguishing the fluorescent lamp in conjunction with the stop of the descent of the elevator.

[0007]

Since the present invention is configured as described above, one of the two fluorescent lamps set out of the two sets of fluorescent lamps can be set according to the elevator stop condition, that is, whether the elevator has stopped by going up or stopped by moving down. A pair of fluorescent lamps can be turned off.

[0008]

Embodiments of the present invention will be described below with reference to FIG.

FIG. 1 is a circuit diagram showing an embodiment of an elevator car illumination control apparatus according to the present invention.

P and N are power sources, 1 is a normally open contact of a relay which is energized when the elevator is stopped after the ascending operation, 2,
2a is a normally open contact of the relay that is energized when various safety switches provided in the elevator are not in operation, 3a is a normally open contact of the relay that is energized when the door is closed, and 4a is an energization when the elevator is running. The normally closed contact 5 of the relay is a normally open contact of the relay that is energized when the elevator stops after the downward operation. Note that t ₁ and t ₂ are normally closed contacts that open when the timers T ₁ and T ₂ are in operation, and L ₁ and L ₂ are respective sets of a plurality of fluorescent lamps divided into two sets, and L ₁ is the first set. A pair of fluorescent lights,
L ₂ is the second set of fluorescent lamps.

FIG. 2 is a flow chart showing an embodiment of the present invention.

Next, the operation of the elevator car interior lighting control apparatus according to the present invention will be described with reference to FIGS. 1 and 2.

First, the control of the first set of fluorescent lamps will be described.

Whether the car has stopped in a normal state (S
Confirmation of TEP1) is made by closing the contacts 2 and 3 and the contact 4
It is done by the open circuit. Then, the contact 1 is closed due to the stop after the ascending operation (STEP 3), and P-2-3-4
Forming a first circuit -1-T ₁ -N. Then, the timer T ₁ is activated. Then, when the timer T ₁ operates after a predetermined time (STEP 7), the contact t ₁ is opened, and the first set of fluorescent lamps is turned off (STEP 9). This extinguishing means is called the first extinguishing means. After that, when the car is in a traveling state and a traveling preparation state, the first circuit is not formed, the contact t ₁ is closed, and the first set of fluorescent lamps is turned on. As a result, all lights are turned on (STEP 11).

If the timer is not operating in STEP 5, it is repeated until the operation is detected (ST
EP5).

Next, the control of the second set of fluorescent lamps will be described.

First, STEP 2 is performed in the same manner as in the first group,
Confirm that the contact 5 closed and stopped after the descending operation. (STEP2, STEP4) By this, timer T ₂
Is energized to operate after a predetermined time (STEP 8), contact t
₂ is open, so the 2nd set of fluorescent lamps goes out (STEP
10). This extinguishing means is called the second extinguishing means. When the car is in the traveling state and the traveling preparation state, the second circuit is not formed, the contact point t ₂ is closed, and the second set of fluorescent lamps is turned on. As a result, all lights are turned on (STEP 11).

If the timer is not operating in STEP 6, the operation is repeated until the operation is detected (S
TEP6).

According to this embodiment, when the elevator is at rest, one of the two sets of fluorescent lamps is turned off under the elevator stop condition, so that the life of the fluorescent lamp is extended. be able to. In other words, there are two possible stopping conditions for the elevator: stopping after rising and stopping after falling, but since this is almost the same number of times, two sets of separated fluorescent lamps are also used. Since the light is turned off almost the same number of times, the life of the fluorescent lamp can be extended.

[0020]

Since the present invention is configured as described above, it is possible to eliminate the anxiety of passengers caused by turning off all the lights in the car and to extend the life of the fluorescent lamp.
