Abstract

PURPOSE:To optimumize luminance to be matched with the lightness of a room, in which a loading state display device is set, by switching the emissive luminance of a display means to display the state of load. CONSTITUTION:When the light of a living room, etc., is turned on, a monitoring means 13 transmits a monitored result to a control means 14. According to the set contents of a luminance setting switch 17 in a luminance setting means 12, the means 14 changes the luminance of a pilot lamp 16 through a display means 11. Thus, the luminance can be made optimum to be matched with the lightness of the room.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a display device that can display the energization status of a load such as a lighting or ventilation fan even at a location far from the load.

BACKGROUND OF THE INVENTION There are cases where it is desired to monitor the energization status of electrical appliances in the home even from a location away from the electrical appliances. For example, you may want to check whether you have forgotten to turn off the lights in your bedroom or living room before going to bed, or you may want to check whether you have forgotten to turn off the air conditioner on the second floor from the entrance before going out. For example, if you want to check the status of lighting fixtures in the living room from the bedroom, this can be realized by a monitoring system as shown in FIG. 3. In FIG. 3, 1 is a lighting fixture in the living room. Reference numeral 2 denotes an adapter connected to the lighting fixture 1, which detects the energization state of the 1, and transmits a load state signal 4 indicating the energization state of the load to the load state display device 5 in the bedroom through the signal line 3. The load state display device 5 receives this load state signal 4, determines the energization state of the lighting fixture 1, and displays the result. Therefore, it is possible to check the energization status of the lighting fixtures in the living room from the bedroom. An example of a conventional load status display device is shown in FIG. Reference numeral 6 denotes a pilot lamp, and its lighting indicates the energized state of the load.

When the load is not energized, the pilot lamp 6 is off. FIG. 5 is an example of a block diagram showing the configuration of a conventional load status display device. Reference numeral 7 denotes a display means for displaying the energization state of the load, and corresponds to the pilot lamp 6 in FIG. 4. Reference numeral 8 denotes a monitoring means for monitoring the state of the load. In the example shown in FIG. 3, the monitoring means 8 monitors the energization state of the load based on the load state signal 4. In the example shown in FIG. Reference numeral 9 denotes a control means for controlling the display means 7 according to the monitoring result 10 of the monitoring means 8.

Problems to be Solved by the Invention However, conventionally, pilot lamps used as display means have been designed to emit light at a constant brightness regardless of the brightness of the room in which the load status display device is installed. Therefore, if the load status display device is designed to be installed in a bright room as standard, the pilot lamp will be too bright in a dark room such as a bedroom when sleeping, causing an eyesore; Products designed with this as standard had the disadvantage that the pilot lamp was too dim in a bright room, making it difficult to check the load status. In order to solve this problem, it is an object of the present invention to provide a load status display device that can vary the luminance of the display means in accordance with the brightness of the room in which it is installed.

Means for Solving the Problems In order to achieve the above object, the present invention provides a monitoring means for monitoring the state of a load, a display means whose luminance is variable for displaying the state of the load, and a luminance system for changing the brightness of the display means. The load status display device comprises a setting means and a control means for controlling the display means in conjunction with the monitoring means and brightness setting means.

Operation By configuring as described above, the load status display device of the present invention can optimize the brightness of the display means by the brightness setting means in accordance with the brightness of the room in which it is installed.

Embodiment FIG. 1 is a block diagram showing the configuration of a load status display device which is an embodiment of the present invention. Reference numeral 11 denotes a display means with variable luminance for displaying the energization state of the load. Reference numeral 12 denotes a brightness setting means for setting the light emission brightness of the display means 11. 1
3 is a monitoring means for monitoring the state of the load. Reference numeral 14 denotes a control means for controlling the display means 11 according to the monitoring result 15 of the monitoring means 13 and the brightness setting means 12. Also, the second
The figure shows an example of the appearance of this embodiment. Reference numeral 16 denotes a pilot lamp, which is a display means with variable luminance, and is designed to indicate the energized state of the load when lit. When the load is not energized, the pilot lamp is turned off by the control means 14. 17 is a pilot lamp 1 that matches the brightness of the room where the load status display device is installed.
This is a brightness setting switch which is a brightness setting means for setting the brightness of 6. In this example, a slide volume is used, and as the knob is moved to the left, the brightness of the pilot lamp 16 can be decreased, and as the knob is moved to the right, the brightness can be increased.

Let us consider a case in which a system is constructed in which the energization state of the lighting fixture 1 in the living room shown in FIG. 3 can be checked from the bedroom using the load state display device configured as described above. living room lighting equipment 1
Take for example the case where is lit. It is assumed that the brightness setting means 12 sets the pilot lamp 16 to be bright during the day (and dimly lit at bedtime).When the adapter 2 detects that the lighting fixture 1 is energized, the load is energized. A load status signal 4 indicating that the load condition is on is transmitted onto the signal line 3. Upon receiving this load status signal 4, the monitoring means 13 outputs a monitoring result 15 indicating that the living room lights are turned on.
is transmitted to the control means 14. After receiving the monitoring result 15, the control means 14 lights the pilot lamp 16 of the display means 11 brightly during the daytime and dimly lights it when it is time to sleep, according to the setting contents of the brightness setting means 12.

Therefore, even if the bedroom is bright during the day, there is no mistaking it, and
The power status of the lighting fixture 1 in the living room can be checked from the bedroom without causing an eyesore even when sleeping.

In this embodiment, an example is given in which a manual brightness setting switch 17 is used as the brightness setting means 12, but a configuration in which the brightness of the room is detected using an illuminance sensor and the brightness of the display means is changed is also possible. Conceivable.

Effects of the Invention As described above, according to the present invention, it is possible to provide a load status display device that can display the load status with appropriate brightness according to the brightness of the room.
