Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a lighting system that actively promotes improvement of lighting control and operability in response to actual life situations.

(Conventional technology) Lighting control technology has become popular for the purpose of ensuring appropriate illuminance in illuminated areas, saving power, and saving labor by automatically performing operations such as blinking and dimming lights. It's coming.

Conventional lighting systems that perform lighting control include centralized control methods used in large-scale lighting systems such as offices and stores. and connect each group of lighting fixtures and the central control device with each electrical wiring.
Then, taking into consideration the location, purpose, and time schedule of each group of lighting fixtures, such as the time of day and day of the week, dimming control is performed centrally for each group through each electrical wiring by a central control device.

On the other hand, small-scale lighting systems for residential use and the like are known in which lighting equipment can be turned on and off and dimmed by remote control from a remote controller.

(Problem to be Solved by the Invention) However, in the above-mentioned centralized control type lighting system, special wiring work is required to connect the central control device and each group of lighting equipment with electrical wiring. It is inconvenient because it is not easy to configure the system, such as the breakdown of groups of lighting fixtures and the distribution of each group.The system configuration cannot be easily changed, and furthermore, the system configuration is large and requires electrical wiring. The entire system is expensive due to the required construction work. In addition, converting existing lighting equipment to this lighting system complicates electrical wiring work, which hinders its widespread use. Moreover, since the installation location of the central control device and the installation location of the lighting equipment do not necessarily correspond to each other, it is not possible to manage the lighting in a way that truly corresponds to the lighting in important real-life situations.
There may also be cases where the lighting environment does not correspond to the user's preferences.

Furthermore, since it is not possible to finely manage lighting for each location and purpose of use, there are locations where the illuminance is higher than necessary, making it difficult to achieve sufficient power savings.

On the other hand, in small-scale lighting systems such as those for residential use, human senses are used to determine the lighting required for actual living situations. In other words, the lighting equipment to be controlled is selected based on the purpose of use such as the user's life situation, work content, and preferences such as age, gender, personality, etc., and operations such as turning on, dimming, turning off, and dimming are performed. There is.

However, the more advanced the dimming content is in order to respond in detail to various living situations and individualities, the more complicated the management becomes in actual living situations, and the functions are often not fully demonstrated.

Furthermore, if we consider human behavior by classifying it into activity and rest, activities include dynamic activities such as sports and parties, and static activities such as conversation and eating, while rest includes activities such as listening to music and reading. There is dynamic rest and static rest such as sleep. However, in reality, due to the complicated operation, there is a problem that the lights tend to turn on only when the lamp is at rest and turn on in other cases.

In addition, the installation location of the lighting equipment such as ceiling, hanging, wall, floor or desk top, the type of light source such as incandescent lamp, fluorescent lamp, rod tube, ring tube, compact fluorescent lamp or color rendering, direct lighting,
The effects of lighting can be achieved through lighting methods such as indirect lighting, local lighting, or auxiliary lighting, the design of fixtures, and their combinations, thereby increasing the richness of life. For example, depending on the lifestyle, a luxurious Jumpria can be placed in the center of the room during a party to concentrate the attention of the participants, spotlights on the wall can create a gentle atmosphere, or during a meal Brighten up the dining table to help communicate with family members, and keep the desk lighting appropriate when reading.
Others can prevent mental fatigue by using indirect light, or turn on only a backup light next to the bed when sleeping, which allows for a sound sleep and prevents anxiety at night. However, when trying to create such a lighting effect, the number of lighting equipment increases, the number of control switches increases, the locations for installing the switches also expand, the complexity of construction increases, and the method of use increases. As a result, ordinary users feel increasingly tired and complicated, which hinders the development of these lighting systems.

Therefore, even if the living situations and types of equipment are diverse, if you set the operation mode in advance, even children and the elderly can easily press the desired operation mode button once during normal use that suits each individual situation. A lighting system has been proposed that allows for lighting effects and for changing the operating mode by performing the same operations as for basic settings.

However, there are times when it is desired to change the operating mode depending on the time, situation, or personal preference. For example, you may want to change the number of dining tables or where the lights are turned on due to unexpected guests, you may want to change the indirect light on the wall for a party, or you may want to increase the illuminance on the desk surface for elderly people to read. be. In this case, there is a problem in that if the basic settings are changed each time, the operation becomes complicated.

In particular, in recent years, with the diversification of lifestyles, it has become desirable to arbitrarily set the illuminance, etc. according to individual life situations and individual preferences.

In addition, in close connection with daily life situations, the dimming content includes delayed lighting that turns on or off after a certain period of time, delayed lighting that turns on or off after a certain period of time, gradual lighting that turns on or off after gradually adjusting the light, gradual turning off,
Sequential control, etc., in which a state is passed through and then transferred to another state, is desired.

However, simply adding these dimming details increases the storage capacity and the number of operation buttons, making the device more expensive and complicated, and the operation becomes complicated.

The present invention was developed in view of the above-mentioned problems, and is easy to operate, frees humans from having to manage lighting using their senses, always achieves optimal lighting and power savings, and allows easy installation and modification of the system. The purpose is to provide a lighting system that can.

(Structure of the Invention) (Means for Solving the Problems) The lighting system of the present invention includes an address designation section for designating an address, a dimming designation section for designating dimming content, and a special control mode designation for designating temporal control. a mode setting section for setting the operation mode in which the dimming contents are set in advance in the address designation section and the dimming designation section, or the special control mode set in the special control mode designation section; a signal transmitter that transmits a dimming command signal including an address signal via a wireless medium according to an address and operation mode set in a mode setting section or a special control mode that operates over time; a remote control section that includes a power supply; an address setting section for setting the address of the device, a signal receiving section for receiving the dimming command signal transmitted via the wireless medium, and an address signal of the dimming command signal received by the signal receiving section being the own address.

and an address setting unit 1 that sets the address order of the reception control unit 13, for example, one of addresses Nα1 to Nα4.
9, and a monitor 20 that displays two lamps, one for increasing brightness and one for decreasing brightness, facing the outside of the appliance and displaying that the brightness is being adjusted to increase or decrease the brightness. In addition, the light control unit 14
is formed by connecting a triac 22 as a power control element to a ballast 21, as shown in FIG.
It is designed to perform dimming. Further, as shown in FIG. 5, a backup light 24 such as a night light in which a triac 23 as a power control element is connected in series may be connected in parallel with the dimming unit 14.

FIG. 2 shows an example of the mode setting section 7 of the remote controller 1, and 31 is a setting specifying section, with a setting button 32 for specifying the start of mode setting and a setting button 32 for specifying the end of mode setting. The setting end button 33 is provided. Further, the mode specifying section 3 includes buttons 34a to 34e in order of modes 1 to 5 for specifying the dimming state of the lighting fixture section 2. Furthermore, the address designation unit 5 has buttons 3 for addresses Nα1 to Nα4 for designating the lighting fixture unit 2 in which the address order has been set.

Furthermore, the special control mode specifying section 4I3 and the dimming specifying section 6 include an on button 36 for turning on the light source 15, an on button 37 for turning off the light source 15, a preliminary light button 38 for turning on and off the preliminary light 24, and a preliminary light button 38 for turning on and off the light source 15. 50% dimming button 39 to increase or decrease the illumination intensity to 50%
, an all-dot button 40 that turns on all the light sources 15 regardless of the address Nα, an all-off button 41 that turns off all the light sources 15 regardless of the address Nα, a brightness increase 42 that gradually increases the illuminance of the light source 15, a light source 15 for gradual dimming, a good morning mode button 44 for specifying good morning mode as a special control mode, a good night mode button 45 for specifying good night mode as a special control mode, and other special control modes. Special control mode NQ1.2 buttons 46a and 46b are provided for specifying the special control mode NQ1.2.

In addition, in this lighting system, it is possible to control the dimming of a plurality of lighting fixtures 2 with one remote control unit 1. For example, if there are four lighting fixtures 2, the dimming of each lighting fixture 2 can be controlled. In the case of controlling separately, a different address Nα1 to Nα4 is set for each lighting fixture part 2 by the address setting part 19, and if there are multiple lighting fixture parts 2, some of the lighting fixture parts 2 may be controlled separately. When performing dimming all at once, that is, when controlling a plurality of lighting fixtures 2 as one group, the reception control units 13 of the lighting fixtures 2 of those groups
are set in the same address order. Also, a certain address Nα
A plurality of dimming units 1 with one reception control unit 13
4 and the light source 15 may be operated for group control.

Next, a method for setting the basic program for each lighting device section 2 that is set in advance will be explained with reference to the flowchart in FIG. 3. In addition, as mentioned above, it is assumed that there are four or more lighting equipment units 2, and addresses 1IQ1 to 4 are set respectively.

Pressing the setting button 32 of the mode setting section 7 of the remote control section 1 (Step ■), selecting and specifying the mode in the mode specifying section 3 (Step ■), and at the same time pressing the address Nα of the lighting fixture section 2 in the address specifying section 5 Select and specify step ■)
, the dimming state is set using the dimming specifying section 6 (step 2).

For example, in the specified state of mode Nα1, after specifying address No 1, the lighting fixture section 2 of address order 1 is set to turn on by specifying the on button 36, and then after specifying address Na2, By specifying the on button 37, the lighting fixture section 2 at the address N112 is set to off, and then, after setting the address Nα3, by specifying the standby light button 38, the lighting fixture section 2 at the address Nα3 is turned off. 24
After setting address NQ4, 50
By specifying the % dimming button 39, the lighting fixture section 2 in address order 4 is set to 50% dimming. In addition, after specifying the on button 36, on button 37, and 50% dimming button 39, or directly, press the brightness increase button 42 or dimming button 4.
By operating 3, it is possible to set an arbitrary dimming value such as 30% or 80%.

Then, when setting is completed for mode NQ1 and you want to continue setting for other modes, specify the other mode, specify the address, and perform the dimming setting in the same procedure, and then the setting is completed. When everything is completed, specify the setting end button 33 to complete the setting. These basic settings for dimming are stored in the memory of the mode setting section 7 of the remote control section 1 for each mode.

Next, a case will be described in which the illumination by the illumination system whose mode has been set as described above is controlled in a preset basic operation mode.

For example, if you specify mode N (11) on the remote control unit 1,
Each address NQ1 stored in the memory of mode 1
- 4 are transmitted as a dimming command signal including an address signal from the light emitting diode 10 of the signal transmitter 8 via an infrared wireless medium. The transmission of the dimming command signals is performed, for example, in the order of addresses 1 to 4, and each of the dimming command signals is assigned an address Nα1 to Nα4, respectively.

In each lighting fixture section 2, the photodiode 16 of the signal receiving section 17 receives the dimming command signal transmitted from the remote control section 1 via a wireless medium, and sends it to the CPU 18.

All the signals received by the signal receiving section 17 are transmitted to this CP LJ 18, but a dimming command signal including an address signal in an address order other than its own address order set in the address setting section 19 is input. If the order of addresses set in the address setting unit 19 is input, the dimming command signal is accepted and input. Then, the CPU 18 controls the dimming unit 14 in accordance with the dimming command signal, and dims the light source 15. For example, the lighting fixture section 2 to which the on dimming command signal is input.
, the light source 15 is turned on, the light source 15 is turned off in the lighting fixture part 2 to which the OFF dimming command signal is input, and the light source 15 is turned off in the lighting fixture part 2 to which the dimming command signal for 50% dimming is input.
Turn on with 50% dimming.

In addition, when the preliminary light 24 is set, the lighting equipment section 2
turns on the preliminary light 24.

As described above, the lighting corresponding to the intended living situation is set in advance. When the operation mode Nα is specified, the signal receiving unit 17 in the order of each address.

Although they are sent sequentially, they are instantaneous and almost simultaneous, so
With one operation, the lighting equipment section 2 of all addresses Nα can be
They work almost simultaneously.

Further, depending on the situation, a preset basic operation mode is arbitrarily selected from the mode specifying section 3 of the remote control section 1. That is, for example, when it is no longer necessary to turn on a certain lighting fixture section 2, the mode Nα in which the lighting fixture section 2 is set to be turned off is selected using the remote control section 1. By selecting
Lighting can be adjusted to suit the situation.

On the other hand, when each lighting equipment section 2 is in a dimming state set in a certain mode, changes in the usage environment, the density of work, etc.
In the case of manual control where you want to adjust the dimming of a certain lighting fixture section 2 individually depending on the atmosphere to be created, the worker's mood, physical condition, age, eye condition, preference, etc., first, adjust the dimming of the lighting fixture section 2 that you want to adjust. The address order is specified using the remote control section 1, and then the dimming state is specified using the dimming specifying section 6. For example, if you want to dim the lighting fixture section 2 at address Nα1 that is in a lit state, specify the address Nα1 on the remote controller 1 and then operate the dimming button 43 to adjust the dimming for manual dimming. A dimming command signal is transmitted from the remote control unit 1 together with address order 1, and the lighting fixture unit 2 of the corresponding address Nα1 accepts the dimming command signal, and the dimming unit 1
4 to dim the light source 15. This manual adjustment can be set to turn on, turn off, brighten, dim, 50% dimming, and standby light, and even if the basic operation mode has already been set, manual dimming is performed with priority.

In this case, the illuminance can be adjusted while checking it from the user's location.

Further, as special control modes, delay control in which the lamp is opened for a certain period of time, gradual control in which the illuminance is gradually brought to a target level, and sequential control in which the illuminance reaches a certain mode and then reaches another mode can be performed. For example, by operating the good morning mode button 44 on the remote controller 1, the illuminance of the lighting fixture section 2 can be gradually increased using the gradual control shown in the table, or the preliminary light 24 can be turned off and the lighting fixture section can be turned off using sequential control. 2. Increases the illuminance, irritates the eyes, and suppresses dazzling. By operating the sleep mode button 45, the current lighting state of the lighting fixture section 2 can be changed to only the backup light 24 to be turned on after a certain period of time using delay control.
By gradual control, the current lighting state of the lighting fixture part 2 can be reduced and turned off, or by sequential control, the current lighting fixture part 2 can be turned off.
After the light is dimmed and turned off in the lit state, the preliminary light 24 is turned on to provide time for operation confirmation, etc. Furthermore, the buttons 46a and 46b of special control mode order 1.2 can be set to, for example, delay control, gradual control, and sequential control having temporal elements shown in the table. For example, as a delay control, the lighting fixture section 2 such as a toilet light or a hallway light is turned off after a certain period of time has elapsed after the operation. In addition, as a gradual control, after the operation, the lighting equipment section 2 in the audiovisual room is turned on by gradually increasing the illuminance from the off state, or is turned off by gradually decreasing the illuminance from the on state. Further, as a sequential control, after turning off the preliminary light 24 after the operation, the lighting equipment section 2 of the audiovisual room is turned on by gradually increasing the illumination intensity of the lighting equipment section 2, or the lighting equipment section 2 of the audiovisual room, toilet light, and hallway light are turned on. The lighting equipment section 2 is turned off by lowering the illuminance from the lighting state, and the preliminary light 24 is turned on.

These batch control, delay control, or sequential control are set by the special control mode specifying section 4 of the remote control section 1, and then a dimming control signal is sequentially outputted over time using a timer or the like of the mode setting section 7. Each lighting device section 1 is dimmed over time using a dimming control signal that is output each time.

In addition, as a collective control shown in the table, by operating the all-dot button 40 on the remote control unit 1, all the lighting equipment units 2 or auxiliary lights 24 are turned on, and by operating the all-off button 41, all the lights are turned on. The instrument section 2 is turned off.

By performing collective control in this way, it is easy to confirm the lighting during construction inspections, turn on the lights all at once during construction inspections, turn on people, start work, and in emergencies; It is easy to confirm that the lights are off during inspections, turn off the lights all at once when people are leaving, work is completed, going out, or going to bed.

Note that these special controls and collective controls are set with the highest priority.

(See next page) To cancel these manual controls, special controls, and batch controls, specify the mode again in the mode specifying section 3.
Manual dimming or total lights-out is canceled, and dimming control corresponding to the specified preset basic/book mode is performed.

When group-controlling several lighting equipment sections 2 as one group, the same address company is set for each group, but when it is desired to change the group configuration, the address Nα is set by the address setting section 19 of each lighting equipment section 2. This can be easily done by simply changing the settings.

In addition, if you want to change the dimming mode of each address in accordance with your daily life situation, such as changing the purpose of use, changing your preferences, or changing your seat, you can set the mode by making a new mode setting in the setting designation section 31. All you have to do is change the . Also,
Manual override functions may also be used.

As mentioned above, by connecting the lighting device section 2 to the remote control section 1 via a wireless medium, there is no need for special wiring work, and the dimming control group can be changed simply by switching the address of the lighting device section 2. This can be done easily, and the remote control unit 1 having the mode setting unit 7 can be moved to any location, so the system configuration can be small-scale and the system can be made inexpensive. Furthermore, since the installation location of the remote control unit 1 having the mode setting unit 7 can be made to correspond to the installation location of the lighting fixture unit 2, management that truly corresponds to lighting conditions in practically important living situations can be performed. , and it is also possible to manage each individual lighting fixture section 2 within the group. Furthermore, since the lighting in real life situations can be managed in detail, it is possible to achieve the necessary and sufficient amount of electricity costs for lighting, that is, to save power. Moreover, by specifying the purpose of use such as the user's life situation, work content, and preferences such as age, gender, and personality,
Since the desired operating mode of the lighting is directly set, humans are freed from the task of controlling the lighting using their senses. Additionally, it is easy to set and change the basic operating mode and to prioritize manual operations.

Such a lighting system can provide sophisticated lighting effects with simple operations in places such as bedrooms and living rooms where lighting effects are desired depending on the situation in daily life.

Furthermore, for example, in places where daily life is simple, such as entrances and hallways, a dimming mode of turning on, dimming, and turning off the light may be used. in this case,
Since the reception control unit 13, the dimming unit 14, and the remote control unit 1 can be made simple, the lighting system can be constructed at low cost.

Note that when performing group control on a plurality of lighting fixture sections 2, if it is assumed that the group will not be changed, the following applies to a plurality of lighting fixture sections 2 having only the light source 15 and the dimming unit 14. One reception control unit 13 may be shared.

Further, on a large floor such as an office or a store, a plurality of remote controllers 1 may be used together, and each remote controller 1 may control a plurality of lighting fixtures 2 at each predetermined location.

In addition, in the case of special control modes such as delay control, gradual control, or sequential control, the remote controller 1 does not control over time;
The remote control unit 1 outputs a dimming control signal including a temporal control signal in advance, and the timer circuit or the like of the dimming control unit 18 of the lighting fixture unit 2 controls each lighting fixture unit 2 over time. You can also do this. Furthermore, the lighting equipment section 2 sets the contents including the temporal details in the dimming control section 18 in advance, and the lighting fixture section 2 is controlled over time using the dimming control signal that does not include the temporal control signal. May be controlled.

Also, if you change your living situation from a performance room with a piano etc. to a bedroom with a bed, or if you move to a different room,
Even if there are a large number of lighting equipment parts 2 or a plurality of dimming contents, they can be easily controlled by hand with one remote control part 1.

Furthermore, by specifying the user's living situation, purpose of use such as work content, age, gender, personality, etc., the desired lighting mode can be directly obtained, which is actually important. It is possible to obtain a lighting effect that truly corresponds to the situation of daily life, save power, and free up the work of managing lighting each time using human senses.

〔Effect of the invention〕

According to the present invention, the address is specified in the address specification section,
The dimming specification section specifies the dimming content.The mode setting section sets the preset address and dimming content mode, which eliminates the task of managing the lighting of multiple lighting fixtures using human senses. Furthermore, it is possible to perform dimming control including temporal content in the special control mode, making dimming easier. By specifying the address in the specification section and specifying the dimming content in the dimming specification section, you can change the dimming content while maintaining the preset dimming content, so you can achieve optimal lighting and power saving. In addition, by connecting the remote control unit with the mode setting unit and the lighting equipment unit without any need for special wiring work, for example, when controlling multiple lighting equipment units in a group, the breakdown of the group can be easily realized. It is also easy to change the position of each group and the location of the remote controller, making it easy to install and change the system.
