Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to improvement of a lighting device in an elevator car including a plurality of lighting lamps.

[0002]

[Prior art]

 As described in Japanese Utility Model Laid-Open No. 60-173574, a conventional lighting device divides a plurality of lighting lamps in a car into two sets, one set of which is constantly lit, and the other set is in standby by the car. A device has been proposed in which when a call is lost, that is, when a door is closed and a door is stopped, the light is turned off after a predetermined time from that time, and is turned on when the standby state is released.

[0003]

[Problems to be solved by the device]

 In the above-mentioned conventional device, one set of lighting lamps is always turned on, and therefore has a shorter life than other sets of lighting lamps. Therefore, the number of times of replacement of lighting lamps is increased and maintenance is troublesome. In addition, there is a problem that power consumption increases because the capacity of the lighting is large and the lighting is continuous. Moreover, since only a part of the illuminating lamp is turned on, the design is not good.

In view of the above-mentioned drawbacks, the present invention is to provide an illumination device in an elevator car, which consumes less power of an illumination lamp that is turned on during standby, has a long life, and has a good design.

[0005]

[Means for Solving the Problems]

 The purpose of this is to provide a small-capacity second illuminating lamp installed in the car in the illuminating device in the car of the elevator composed of the plurality of first illuminating lights, and after the car is in the standby state. This is achieved by providing a timer device that operates after a predetermined time and a lighting means that turns off the first illumination lamp and lights the second illumination lamp when the timer device operates.

[0006]

[Action]

 According to the present invention, when the elevator is in operation, the first illumination lamp is turned on and the small-capacity second illumination lamp is turned off. When the elevator is in the standby state and a predetermined time, for example, 3 minutes has elapsed, the timer device operates and the lighting means turns off the first illumination lamp and turns on the second illumination lamp. Therefore, since the lighting lamp has a small capacity, power consumption is small, and the lighting time is short, so that the life of the lighting lamp can be extended.

[0007]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

FIG. 2 is a front view of a car incorporating the lighting device according to the present invention. In the figure, 1 is a car, 2 is a car door, 3 is an operation panel provided on a side plate of the car door 2, 4 is an indicator provided on the upper part of the car door 2, 5 is a ceiling of the car 1, and 5 is a ceiling 5. The first illuminators L ₁ and L ₂ having a large capacity and the second illuminator L ₃ having a small capacity are provided between the _first illuminators L ₁ and L ₂ .

FIG. 1 is an electrical connection diagram of a lighting device according to the present invention. In the figure, U and V are AC power supply terminals, 40a is a normally open contact of a relay (not shown) that detects that all elevator doors are closed, and 60b is a relay that is not shown that detects that there is an elevator call. Closed contact, T is, for example, a timer set to 3 minutes, Ta is its normally open contact, Tb is its normally closed contact, L ₁ and L ₂ are the above-mentioned first illumination lamp, and L ₃ is the second illumination lamp. It is a lighting.

Next, the operation of this embodiment will be described.

When the elevator is operating, the contact 60b is always open. Therefore, since the timer T does not operate, the contact Tb is closed and the contact Ta is open. Therefore, the first illumination lights L ₁ and L ₂ are turned on, and the second illumination light L ₃ is turned off.

Next, when the elevator is in a standby state, that is, when there is no call and the door is closed, the contacts 40a and 60b are closed, and when the timer T starts counting for 3 minutes, the timer T operates and the contact Tb is turned on. The first illumination lamps L ₁ and L _{2 that} are opened are turned off, the contact Ta is closed, and the second illumination lamp L ₃ is turned on.

In this way, for example, when cleaning the inside of the car while the elevator is on standby, even if the cleaning work takes 3 minutes or more, a power failure does not occur, and therefore the work can be performed with peace of mind. Further, since the second lamp has a small capacity, it consumes less electricity, and since the elevator is on standby for the lighting time, the lighting time is short and the life can be extended. Further, since the second illumination lamp L ₃ is arranged in the middle of the first illumination lamps L ₁ and L ₂ , it is good in design.

[0014]

[Effect of device]

 As described above, according to the present invention, the second small-capacity lighting lamp is provided in the middle of the first lighting lamp, and the first lighting lamp is turned off after a lapse of a certain time from the standby state. Since the second illuminating lamp is configured to be turned on, there is an effect that the electricity consumption is small and the life of the second illuminating lamp can be extended when in the standby state. Further, since the second illumination lamp is also provided independently, it is possible to improve the design.

With this configuration, for example, when cleaning the inside of the car while the elevator is on standby, even if the work takes 3 minutes or more, no power outage occurs, so that the work can be performed with peace of mind. There is also.
