Abstract

PURPOSE:To quite obviously see many light adjustment control conditions of light sources on the small space of a liquid crystal display means by having a display means as the liquid crystal display means that displays the light adjustment control conditions including turning on and turning off each of the light sources in a graph representing such conditions relative to the passage of time. CONSTITUTION:A light controller has a display unit 2 as a liquid crystal display means which displays each of preprogrammed time schedules, and also has light source terminals 4 each of which is provided with such light sources 3 as a fluorescent lamp, an incandescent lamp or the like, a manually operating wall-switch 5 and an optical sensor terminal 7 which is provided with an optical sensor 6 all connected thereto via a transmission line 8. Namely, the liquid crystal display means 2 or the display unit 2 is used to display light adjustment control conditions of the light sources, including turning on and turning off each of the light sources whose operations are preset respectively by the time schedules in a graph representing such conditions relative to the passage of time. Many light adjustment control conditions of the light sources can thus be seen quite obviously on the small space of the display means.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a lighting control device that controls a light source according to a preprogrammed time schedule.

(Prior Art) As a display unit of a conventional lighting control device of this type, for example, a device is known that displays time and a control state of a light source in correspondence with letters and numbers.

However, in the case of such a device, if the number of times and the control status of the light source is increased, the display section must be made larger, resulting in a space problem for the device.

Further, if a display is to be performed on a small display section, operations such as scrolling must be performed, so many operations cannot be understood at a glance.

Furthermore, there is also known a device that displays the operation of -day in a ring shape, and displays the display by turning on the light when the light is on and turning off the light when the light is off.

However, this device has the problem that it can only represent two states: on and off.

(Problem to be Solved by the Invention) As mentioned above, when expressing the time and the control status of a light source using numbers and letters, there is a problem in the space of the device to express a large number of numbers. cannot know the operating status of the

Further, when displaying by turning on and off, long-time operations can be displayed in a small space, but only two modes can be displayed.

The present invention was made in view of the above problems, and an object of the present invention is to provide a lighting control device that allows many control states to be known at a glance in a small space.

[Structure of the invention]

(Means for Solving the Problems) The present invention provides a lighting control device that has a light source that is controlled according to a preprogrammed time schedule, and is equipped with a display means that displays the programmed time schedule. The display means is a liquid crystal display means that displays a graph showing the dimming control state including turning on and turning off the light source in relation to time.

(Function) The present invention uses a liquid crystal display means to display the relationship between the dimming control state including turning on and turning off the light source, which is set according to a time schedule preprogrammed in the display section, and the time, in a graph on a liquid crystal display means.

(Example) Hereinafter, one example of the lighting control device of the present invention will be described with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a lighting control device, and this lighting control device 1 is equipped with a display section 2 as a liquid crystal display means for displaying a preprogrammed time schedule. The lighting control device 1 also includes a light source terminal 4 equipped with a light source 3 such as a fluorescent lamp or an incandescent lamp, a wall switch 5 for manual operation, and a light sensor terminal 7 equipped with a light sensor 6 for transmission. It is connected via line 8.

Next, the lighting control device 1 will be explained with reference to FIG.

In FIG. 2, reference numeral 11 denotes a lighting control device main body, and this lighting control device main body 11 includes name plates 12 on which the names of each light source 3 are written, and individual switches 13 provided corresponding to these name plates 12. and three individual switch units 15 having individual monitors 14 made of light emitting diodes that indicate the operating states of these individual switches 13, a zone plate 16 in which zones constituted by a plurality of light sources 3 are described, and these zone plates 16. a zone switch unit 19 having a zone switch 17 provided corresponding to the zone switch 17 and a zone monitor 18 consisting of a light emitting diode that indicates the operating status of these zone switches 7; and a display unit including a liquid crystal display panel 21 as a liquid crystal display means. 2, a control switch section 25 equipped with a control switch 22 and a control monitor 23 consisting of a light emitting diode provided corresponding to these control switches 22, a numeric keypad 24, etc., and a card reader section 26 for inputting the contents of the card. It is equipped with

Furthermore, as shown in FIG. 3, the liquid crystal display panel 21 of the display section 2 includes a line graph that displays the state of the light source 3 in accordance with time.

Next, the operation of the above embodiment will be explained with reference to the flowchart shown in FIG.

First, a time schedule is input manually using the keys on the control switch section 25 (step 1).

Next, you can make up to 20 settings, so 2
Step 2) to judge whether or not 0 pieces have already been set.
If 0 items have been set, proceed to the next process, and if 20 items have not been set, set the time schedule in the memory in chronological order. (Step 4) Then, in order to set the count value of the first operation to "1", the count value is set to rlJ (Step 5).

Next, read the time schedule indicated by the count value from the memory. Step 6 >1' The read contents are rFFJ
If it is not rFFJ, the operating time is displayed below the count value as shown in FIG. 3 (step 8). Then, based on the code table shown in FIG. 5, the corresponding contents of the code table shown in FIG. 6 are displayed as shown in FIG. 3 (step 9). Then, the current count value is set as the previous count value (step lO), and 1 is added to the count value (
In step 11), it is determined whether the count value is 21 or not. In step 12), if the count value is 21, the process proceeds to the next process, and if the count value is not 21, the process returns to step 6. If rFFJ is determined in step 7, count data after the end of the time schedule is displayed based on FIG. 5 (step 13). Then, 1 is added to the count value (step 14), and it is determined whether the count value is 21 or not (step 15). If the count value is not 21, the process returns to step 13, and if the count value is 21, the next Proceed to processing.

In this way, as shown in FIG. 3, the relationship between time and the lighting state of the light source 3 is shown in a line graph.

In addition, in FIG. 3, the lights are turned off even after the lights are turned off, but this is because the light source 3 may be turned on by manual operation of the wall switch 5 or the like even after the lights are turned off.
This is because in this case, the light source 3 is turned off to prevent forgetting to turn it off.

〔Effect of the invention〕

According to the present invention, since the control status of the light source is displayed on the liquid crystal display in the form of a graph in relation to the time, the control status of many light sources can be displayed in a small space, so that many control statuses can be understood at a glance in a small space. be able to.
