Abstract

PURPOSE:To provide eventual possibility of exposure over the rated output if necessary by furnishing an illumination fixture and an illuminance comparing/ judging part to compare the sensed illuminance value with the target illuminance value for correction of the illuminance, and controlling between them by a remote control part with a built-in power supply and signal transmitting part to transmit a dimming command signal through a radio medium. CONSTITUTION:If for ex. sufficient illuminance is attainable with three illumination fixtures 13a-13c in rated ligfting condition, a remote control part 12 judges that it is in proper illuminance, and the lighting shall go on as it is. During outside the working time, only the central fixture 13b is lit while the other fixtures 13a, 13c put off, and now proper illuminance can not be obtained with the fixture 13b alone, so that the remote control part 12 sends an incremental dimming control signal to the light source 13 for the fixture 11b, and a dimming unit 14 having received it generates an output higher than the rated output, for ex. 150%, from the light source 13 with the other fixtures 11a, 11c left put off, which should sink the power consumption while the proper illuminance is kept.

Description

[Detailed description of the invention]

(To 1 of the Invention) (Industrial Application Field) The present invention relates to a lighting system that actively promotes control of illuminance of illuminated parts such as hands. (Prior art) Illuminance control in lighting is used to ensure appropriate illuminance for the illuminated area, to reduce the electricity bill for lighting by just the necessary amount, to save electricity, to turn lights on and off, etc. Conventional lighting systems that perform 1° illuminance control, which are becoming popular for the purpose of saving labor by automatically performing operations such as dimming, include centralized lighting systems used in large-scale lighting systems for offices, stores, etc. The control method is [V], in which several lighting fixtures are grouped together to form multiple groups, the lighting fixtures in each group are connected to the central control device using electrical wiring, and each Taking into consideration the location, purpose, and time schedule of each group's lighting equipment, each group F5 is
Four-light control is performed in a concentrated manner. In addition, in such a centralized & + control type 1 type, for example, a light sensor 1 is installed near the window.
There is also a lighting system that uses a light sensor to detect outside light such as sunlight near a window and use it as a control factor. On the other hand, some small-scale lighting systems, such as those for residential use, are configured to allow dimming of lighting equipment to be controlled remotely 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 and optical sensors with electrical wiring. The system configuration, such as the breakdown of lighting equipment groups, the layout of each group, and the installation location of optical sensors, cannot be easily changed, and the system configuration is large-scale and requires wiring work. Due to the requirements, the system is expensive. Moreover, the installation location of the light sensor, which is usually installed in a place where the illuminance of sunlight can be detected, such as near a window, does not necessarily correspond to the location of the question on the lighting equipment. Management that truly responds to illuminance is possible, and
Because each group is managed collectively, it is not possible to manage individual lighting fixtures within the group. Furthermore, since detailed control is not possible for each location of use, and it is not possible to truly control the illuminance of the illuminated area, it is not possible to achieve sufficient electricity costs for lighting for the required minute, that is, to save power. . On the other hand, in small-scale lighting systems such as those for residential use, the necessary illuminance is determined at hand using human senses and dimming is commanded manually, making it difficult to obtain appropriate illuminance control. It is troublesome to manually adjust the brightness each time the illumination intensity changes. By the way, in the illuminator 61 in an office or the like, the maximum light output of the light source is set as the rated output (100%), and the light source is not contaminated, deteriorated, or
Turn on all lights or multiple lights after considering interior dirt (reduction in reflectance) and proper placement of lighting equipment (installation spacing).

[Lighting equipment is arranged so that an appropriate level of illuminance can be obtained at Nodagi. However, for example, the time period (
(outside working hours), number of users, room makeover, lighting level 1?
Due to changes in usage conditions, such as changes in people's age, intensity of work, and the monopolization of lighting by personal purposes, it becomes impossible to obtain the appropriate illuminance for areas to be illuminated, such as at hand, when dimming lighting equipment. Therefore, it is necessary to turn on all or multiple lights. That is, for example, FIG.
), when the appropriate illuminance of the desk surface is obtained with the light from three lighting fixtures A, B, and C, which are in the rated (100%) lighting state, the working hours will be as shown in Figure 6 (c). If you leave lighting fixture B directly above you outside of business hours, etc. (if you turn off lighting fixtures Δ and C (0%) to save power, the light from lighting fixture B alone will not provide the appropriate illuminance for the desk surface. Therefore, it is necessary to turn on other lighting equipment △, C or use a desk lamp as an auxiliary light source.The present invention has been made in view of the above problems. By using a wireless medium for dimming commands and eliminating the need for wiring work, the system can be easily changed and the system configuration can be made small and inexpensive.In addition, by controlling the illuminance at the illuminated area, , it is possible to obtain the optimum illuminance and save power, freeing people from the task of managing illuminance intuitively, and even when the light source is turned on at a higher light output than its rated output, the appropriate illuminance can be obtained. [Structure of the Invention] (Means for Solving the Problems) The lighting system of the present invention includes a light source and a light control unit that controls the light source. , a signal receiving unit that receives a dimming command signal transmitted via a wireless medium, and a lighting fixture having a dimming control unit that controls the dimming unit based on dimming command No. 111 input from the signal receiving unit. , an illuminance detection section, an illuminance comparison and determination section that compares the detected illuminance value from this illuminance detection section and a target illuminance value, determines illuminance correction, and outputs a dimming command signal; The light control unit includes a signal transmission unit that transmits a dimming command signal via a wireless medium and a remote control unit having a power source, and the dimming unit of the lighting equipment unit is capable of dimming the light output of the light source to a higher output than the rated output. (Function) In the lighting system of the present invention, a remote control unit is placed at the illuminated area where the appropriate illuminance of 1q is desired, such as a desk surface where work is performed, and the illuminance detection unit of this remote control unit is used to adjust the illuminance. is detected, the detected illuminance value and the target illuminance value are compared, the illuminance correction is determined, and a dimming command signal is transmitted via a wireless medium from the IHA S transmission section of the remote control section.On the other hand, in the lighting equipment section, The signal receiving unit receives the dimming command No. 111 transmitted from the remote controller via a wireless medium, and the dimming control unit controls the light source based on the dimming command signal. 3.Also, if the light source in the lighting equipment section is lit at its rated output but the proper illuminance cannot be obtained in the sushi room, use the dimmer unit in the lighting equipment section to adjust the light output of the light source to its rated output. J. Adjust the light to high output. (Example) Hereinafter, the configuration of an example of the present invention will be described with reference to the drawings. Figure 1 shows the configuration of the lighting system, which includes a lighting fixture section 11 such as a ceiling light, hanging lamp, stand light, etc., and a remote control section 12 placed on a nearby illuminated area such as a desk surface.

Note that the light control unit 14 can continuously control the light between 9:I (0%) of the light source 13 and 6 higher output (for example, 150%) than the rated output (100%) of the light source 13. Moreover, the light source 13 to be dimmed by the dimming colas 1 to 14 can be dimmed to a higher output than the rated output even if a general-purpose fluorescent lamp or incandescent lamp is used. , fluorescent lamps or incandescent lamps of a type particularly suited for high-output dimming may be used. This reception control unit 1-15 is connected to the light control unit 14 for the lighting equipment section 11, and is incorporated into the body or as an adapter, and serves as a light control unit that controls the light control units 1-14. 16, and this CPU 16 has an address setting section 1 for setting the address number of the reception fee mconit 15, for example, address N (one from 11 to 4).

FIG. 2 shows an example of the illuminance setting section 23 of the remote control unit 12, and 31 is a setting designation section, with a setting button 32 for specifying the start of illuminance setting and a setting button 32 for specifying the end of illuminance setting. The setting end button 33 is provided. Moreover, 34 is a mode designation part, which is provided with buttons 35a to 35e for modes N01 to 5 for designating the dimming state of the lighting fixture part 11. Furthermore, 36 is an address designation part, which is an address N for designating the lighting fixture part 11 to which an address No. is set.
o, It is equipped with buttons 1 to 4, 37a to 37d. Furthermore, 381. , I. The dimming designation section includes an on button 39, an on button 40, an automatic dimming 41.50% dimming 42, a total off mark 43, a brightness increase 44, and a dimming 45, respectively. d3, the dimming designation section 38 may be provided with a button to designate a higher output than the rated output (1 (10%)) of the light output of the light source 13, for example, 150% dimming. Although not shown in the section 12, an illuminance setting section 23 tjT has a slurry setting section 23 for adjusting the target illumination value.
In addition to having an id switch and a rotary switch, it also has a monitor that displays, for example, two lamps for brightness increase and dimming to indicate that the brightness is being adjusted to increase or decrease the brightness toward the target dimming value. In addition, in this lighting system, it is possible to control the dimming of a plurality of lighting fixtures 11 with one remote control unit 12. For example, if there are four lighting fixtures 11, the dimming of each of the lighting fixtures 11 can be controlled. In the case of controlling separately, a different address No. 1 to 4 is set for each lighting fixture section 11 by the address setting section 17, and if there are a plurality of lighting fixture sections 11, some of them 11 in a group, that is, when controlling a plurality of lighting fixtures 11 as one group, the lighting fixtures 11 of each group
to the same address number. Next, a method for setting the dimming of each lighting device section 11 will be explained with reference to the flowchart of FIG. 3. In addition, as mentioned above, there are four or more lighting equipment units 11, and address Nos. 1 to 4.
It is assumed that each of these is set. Press the button 32 of the illuminance setting section 23 of the remote control section 12, select and specify the mode No. in the mode specifying section 34, and select and specify the address No. of the lighting fixture section 11 in the address specifying section 36. , the dimming state is specified in the dimming specifying section 38. For example, when mode No. 1 is specified, address No. 1 is specified (by specifying three on buttons, the lighting fixture section 11 of address No. 1 is set to turn on, and then the address No. 1 is set to turn on. , 2, by specifying the on button 40, the lighting fixture section 11 of address No. 2 is set to off, and then, after setting address N. 3, by specifying the automatic dimming 41. Set the lighting fixture section 11 at address No. 3 to automatic dimming,
Next, after setting Address No. 4, the lighting device section 11 of Address No. 7 is set to 50% dimming by specifying the 50% dimming button. In addition, after specifying the on button 39, on button 40J3J: and 5o% dimming button 42, or by directly operating the brightness increase 44 or dimming 45, for example, 30% or 80%
It can be set to any dimming value such as %. And mode N
After completing the settings for Q1, continue with C for other modes.
When making settings, after specifying other modes,
Specify the address and set the dimming by following the same steps as f), OFF, and YES, and when all settings are completed, specify the setting end button 33 to complete the setting. These dimming settings are stored in the memory of the illuminance setting section 23 of the remote control section 12 for each mode. Next, a description will be given of the illuminance control operation performed by the lighting system in which the dimming setting has been performed as described above. For example, when mode No. 1 is specified with the remote controller 12, the dimming setting contents of each address No. 1-/I stored in the mode Na1 are signaled as a dimming command signal through the illuminance comparison/determination section 22. The information is transmitted from the transmitter 24 via a wireless medium such as infrared rays or radio waves. The transmission of this dimming command signal is performed, for example, in the order of address No. 1-4, and each dimming command signal includes each address No. 1-4.
1 to /I are digitized by 1 and 1, respectively. In each lighting equipment section 11, the signal receiving section 18 receives a dimming command signal transmitted from the remote control section 12 via a wireless medium, and
Send to P U 16. This CP 1. ,+16 has
All the signals received by the signal receiving unit 18 are transmitted, but even if a dimming command signal in an address order other than the address Nα set in the address setting unit 17 is input, it is not accepted.
Only when the address NO set in the address setting section 17 is input, the dimming command signal is accepted and input. Then, the CP (J16) controls the dimming unit 14 according to the respective dimming command signal to dim the light source 13. For example, the light source 13 is turned on in the lighting fixture section 11 to which the ON dimming command signal is input. The light source 13 is turned off in the lighting equipment section 11 to which the off dimming command signal is input, and the light source 13 is turned off.
In the lighting equipment section 11 to which the dimming command signal of % dimming is input, the light source 13 is turned on at 50% dimming. Furthermore, if there is an address No. set to automatic dimming, the lighting fixture sections 11 in the address order of A are automatically dimmed. The control operation of this automatic light adjustment is explained in the flowchart of Fig. 4.
1 to 1-0 The illuminance detection unit 21 of the computer unit 12 receives the light from the light source 13 and external light (sunlight, light from nearby lighting, etc.), detects the illuminance, and calculates the detected illuminance value. It is sent to the illuminance comparison and determination section 22. In this illuminance comparison/judgment section 22, the detected illuminance value and the illuminance setting section 2
3, and if it is determined that illuminance correction is necessary, the brightness of the automatic light control will be increased (including turning on from the off state) and the LC will be dimming (including turning off the light).
Outputs the dimming command signal. For example, if the illuminance due to external light is high between 8 and 8, the illuminance value detected by the illuminance detector 21 will be higher than the target illuminance value J. The light source 131 outputs a light dimming command signal, and when the illuminance due to external light decreases in the evening, the detected illuminance value becomes lower than the target illuminance value.
In order to increase the illumination intensity by C, a dimming command signal for increasing the brightness of automatic dimming is output. Note that if it is determined that the illuminance is appropriate, the dimming command signal will not be output, but a dimming command signal that instructs the current status to be maintained may be output. The dimming command signal for dimming or increasing the automatic dimming output from the illuminance comparison/judgment section 22 is transmitted from the signal transmitting section 24 via a wireless medium. In the lighting equipment section 11 set to automatic dimming, when the address numbers match and a dimming command signal for automatic dimming or brightness increase is received, the CPU 16 performs dimming based on the dimming command signal. The light 1 nit 14 is controlled to dim or increase the light source 13. In this way, the remote control unit 12 detects the illuminance, and transmits the dimming command No. 113 for automatic dimming or brightening until the detected illuminance value reaches the target illuminance value, and the automatic dimming is set. The lighting equipment section 11 dims the light source 13 by 1-j based on the dimming command signal. Therefore, for example, by setting the lighting device section 11 above the desk where the worker works to automatic dimming and placing the remote control section 12 on the desk surface, appropriate illuminance at hand can always be obtained. Also, depending on the situation, the mode specifying section 34 of the remote control section 12
Select the mode from. For example, if it is no longer necessary to turn on a certain lighting fixture section 11, the mode number for turning off the lighting fixture section 11 is selected using the remote control section 12. By selecting each mode, you can perform lighting that suits the situation. (b), each lighting fixture section 11 is set in a certain mode,
: When in the dimming state, the odor τ, changes in the usage environment, the density of the work, the production atmosphere, the worker's mood, physical condition, η age, the condition of [1], preference, etc. If you want to manually adjust the dimming individually, first enter the address number of the lighting fixture section 11 you want to adjust on the remote control section 1.
2, and then use the dimming designation section 38 to designate the "1 light state." For example, if you want to adjust the dimming of the lighting fixture section 11 at address No. 1 that is in a lit state, the remote control section 1
After specifying the address No. 1 of 2, by operating the dimming 45, a dimming command signal for manual dimming is transmitted from the remote controller 12 together with the address No. 1, and the corresponding address is No. 1 lighting fixture section 11
receives the dimming command signal and controls the dimming unit 14 to dim the light source 13. This manual adjustment
It can be set to on, off, brightness increase, dimming, 50% dimming, and automatic dimming, and even if automatic dimming is set, manual dimming is given priority. In this case, the illuminance can be adjusted while checking it from the user's location. In addition, by adjusting the target illuminance value with the illuminance setting section 23 of the remote control section 12, the light source 13 of the lighting equipment section 11, which is set to automatic dimming, is dimmed or increased to adjust the illuminance at hand. be able to. In addition, by operating the all-off button 43 of the remote control section 12, all the lighting equipment sections 11 are turned off. Furthermore, if the mode is designated again using the mode designation section 34 of the remote control section 12, manual dimming or total light-off is canceled and dimming control corresponding to the designated mode is performed. In addition, when controlling several lighting fixtures 11 as one group, the same address order is set for each group, but when you want to change the group configuration, each lighting fixture 11
This can be easily done by simply changing the setting of the address Nα using the address setting section 17. In addition, when you want to change the illuminated area to obtain the optimum illuminance by changing your seat, etc., the illuminance detection section 21 can be used.
-] By carrying the control unit 2 to the changed location of the illuminated area, the optimum illuminance of the changed illuminated area can be obtained. If the lighting equipment section 11 is set to automatic dimming, the automatic dimming is set by manual operation as described above. As described above, by connecting the lighting equipment section 11 and the remote control section 12 etc. using a wireless medium, there is no need for special wiring work, and the dimming control group can be controlled by switching the address NQ of the lighting equipment section 11. can be easily changed, and the remote control unit 12 having the illuminance detection unit 21 can be moved to any location, so the system configuration can be small-scale and the system can be made inexpensive. In addition, the installation location of the remote control unit 12, which includes the illuminance detection unit 21, and the installation location of the lighting equipment unit 11 correspond to each other. In addition, it is also possible to manage each individual lighting fixture section 11 within the group. 1 Furthermore,
Since the illuminance of the illuminated area can be controlled in detail, it is possible to achieve the necessary and sufficient amount of electricity costs for lighting, that is, to save power. Moreover, since the illuminance can be adjusted automatically in response to sudden changes in the environment and conditions of use, such as external light, humans are freed from the task of adjusting the illuminance using their senses. By the way, for example, as shown in FIG. 5) (c), the light from the three lighting fixtures 11a, 11b, and 11c, which are lit at the rated output (ioo%), is used to illuminate the illuminated area. The remote control unit 12 that has been installed has an appropriate illuminance, and the lighting fixture 11 directly above it can be used outside of working hours.
If the other lighting fixtures 11a and 11c are turned off (0%) to save power except for the lighting fixture 11b, the remote control unit 12 will not be able to obtain proper illuminance with only the light from the lighting fixture 11b with the rated output (100%). . In this case, the remote control section 12
transmits a dimming command signal to increase the brightness of the light source 13 of the lighting fixture 11b, and upon receiving the dimming command signal, the lighting fixture part 11b uses the dimming control unit 14 to increase the light source 13 at a higher output than the rated output (for example, By adjusting the light to 150%), the remote controller 12 can obtain an appropriate illuminance. Therefore, the other lighting equipment parts 11a and 11c can remain off, ensuring proper illuminance while saving power, and it is not necessary to use an auxiliary light source such as a desk lamp. Note that if the lighting fixture section 11b is set to automatic dimming, the light source 13 is dimmed to high output by the dimming command signal for automatic brightness from the remote control section 12, and if it is set manually, the remote control section 12 brightness increase buttons 44 and 15 not shown
By operating the 0% dimming button, the light source 13 is dimmed to a high output. In addition, even if there are multiple lights (many lights are on as shown in Figure 5 (2)), for example, the light source may be dirty or deteriorated, the interior may be dirty (reduction in reflectance), etc. When illuminance cannot be obtained, the light source 13 of each lighting equipment section 11
The light output may be dimmed to a higher output than the rated output. In addition, if group control is performed for a plurality of lighting fixtures 11 and it is assumed that the group will not be changed 17, a plurality of lighting fixtures having only a light source 13J3 and a dimming unit 14 may be used. One reception control unit 15 may be used in common instead of the reception control unit 11. In addition, in dog-friendly floors such as offices and stores, multiple remote control units 12 may be used together to control multiple lighting equipment units 11 at each predetermined location using each remote control unit 12'('). [Effects of the Invention] According to the present invention, by connecting the lighting equipment part and the remote control part having the irradiance detection part through a wireless medium, there is no need for special wiring work, and for example, it is possible to connect multiple lighting equipment parts. In the case of group control, changes to the system such as changing the group breakdown A3 and the number of parts for each group or changing the location of the remote control unit can be easily performed, and the system configuration can be small-scale and inexpensive. By placing the remote control unit on the illuminated area where you want to obtain the appropriate illuminance, such as the desk surface where you work, it is possible to match the illuminance detection unit of the remote control unit with the illuminated area, which is important in practice. Illuminance management that truly corresponds to the illuminance of the illuminated area can be performed, and an optimal 4 [illuminance can be obtained.Furthermore, since the illuminance of the illuminated area can be precisely managed,
Power saving is fully achieved. However, since the illuminance can be adjusted automatically in response to sudden changes in the usage environment and conditions, such as changes in external light, humans can be freed from the task of controlling illuminance based on their senses. In addition, the light output of the light source can be dimmed to a higher output than the rated output with one nit of dimming of the lighting equipment, so even when the light source of the lighting equipment is turned on at the rated output and the appropriate illuminance cannot be obtained, By dimming the light source to a high output, appropriate illuminance can be obtained, and there is no need to turn on other illuminators or the auxiliary light 39, so power can be saved.
