Description

  The present invention relates to a dimming sensor device used for a lighting fixture with an electronic ballast, and more specifically, a pair of dimming for energy saving is provided for a lighting fixture provided in a large number in a store or office. It is related with improvement of controlling to one correspondence.

  Electronic ballasts are well known as ballasts for fluorescent lamps and adopt an inverter type configuration. For example, as can be seen in Patent Document 1, an electronic ballast has an oscillator that outputs a high-frequency voltage, which is applied to a fluorescent lamp to perform lighting, so that it is highly efficient and advantageous for power saving. Is preferred.

In addition, the electronic ballast is characterized in that it is easy to control the output voltage and that the light control for changing the light quantity of the lit fluorescent lamp is relatively simple. Therefore, the light quantity of the fluorescent lamp is controlled to an appropriate value in combination with sensor means for detecting outside brightness, and various proposals for technologies for power saving are seen. For example, in Patent Document 2, there is a proposal of a technique for saving energy with respect to a lighting facility such as a store or an office in which a large number of lighting fixtures are arranged, and among the many lighting fixtures provided indoors, The luminaire on the window side is dimmed to save energy while keeping the whole room bright.

  However, such conventional dimming control techniques have the following problems. In the dimming control of a lighting fixture provided with a large number in the room such as Patent Document 2 described above, the sensor means is installed at an appropriate place in the room, and further, the wiring is routed from the sensor means to each lighting fixture. There is a problem that such installation and wiring work is complicated and time-consuming.

  In addition, the dimming of the lighting fixtures provided in the room appropriately controls the amount of light according to the detection of the sensor means, but when viewed with individual lighting fixtures, the light amount control is inappropriate due to the positional relationship with the sensor means. There will also be an instrument that will come out. For such lighting fixtures, it is desired to optimize the light amount control, but optimization is not easy because of the centralized control by the sensor means that does not have a one-to-one correspondence. In other words, it is necessary to set the mode of dimming operation of the electronic ballast appropriately for each lighting fixture for optimization, and the work of removing and adjusting the reflector of each lighting fixture is complicated, and Actually, it was necessary to contact the manufacturer and call a service man to have the adjustment made on site, and it was impossible for the user to make adjustments easily. Therefore, there is a problem that readjustment is not easy when the indoor environmental conditions change.

  This device solves the above-mentioned problems. The purpose of this device is to adjust the dimming control of a large number of lighting fixtures in a room without the need for installation and wiring, and each lighting fixture can be dimmed individually. A dimming sensor device and a lighting fixture for use in a lighting fixture with an electronic ballast that can be set for operation, can be changed appropriately, and have a high degree of freedom, and can be installed in existing lighting fixtures. It is to provide.

  In order to achieve the above-described object, a dimming sensor device used for a lighting fixture with an electronic ballast according to the present invention is connected to an electronic ballast having an inverter type configuration, and the electronic ballast performs at least a dimming operation. A dimming sensor device that outputs a control signal for performing a support case that can be attached to a lighting fixture having a fluorescent lamp whose lighting is controlled by the electronic ballast, and is detachably attached to the support case A cylindrical main body, and the main body determines whether or not the electronic ballast should be lit in a steady state based on a sensor for detecting a nearby situation and an output of the sensor. A determination unit; an adjusting unit that sets a condition for determining whether or not the determination unit causes lighting in a steady state; and an operation mode when the ballast is not in a steady state lighting state. The control signal for notifying the lighting state determined by the determination unit based on the mode switching switch, the output of the sensor, the determination condition set by the adjusting means, and the operation mode set by the mode switching switch Means for outputting to the electronic ballast (can also serve as determination means), and the adjustment means and the mode switch are exposed on the surface of the main body and are set to be operable from the outside. Configured to be.

  For example, when the main body is formed in a cylindrical shape, it is preferable to provide a mechanism that can be fixed by being rotated while being inserted when the main body is attached to the support case. In particular, in some fluorescent lamps, for example, parts of a cylindrical pair such as a glow lamp are attached and detached. By making the main body cylindrical, the user can smoothly attach and detach the main body without feeling uncomfortable.

  The support case may include a wiring that can be connected to the electronic ballast, and the terminal may be electrically connected to the wiring in a state where the main body is mounted. The various sensors are human sensors that detect heat generation of a human body or the like, and the determination unit is in a steady state when it is determined that a person is present in the monitor area based on a detection signal from the human sensor. It is preferable to provide a function of determining whether to turn on or turn off the light according to the operation mode when it is determined that there is no person in the monitor area.

  Furthermore, the sensor is an illuminance sensor that detects brightness in the vicinity, and the determination unit is lit in a steady state when the ambient brightness detected by the illuminance sensor is darker than the set brightness. In the case where the brightness of the surroundings is brighter than the set brightness, a function may be provided for determining whether the light is dimmed or turned off according to the operation mode.

  Further, the adjusting means may be one that sets the detection sensitivity of the sensor (the determination condition is indirectly determined whether or not the output value of the sensor is equal to or higher than a certain level). Of course, when the sensor output is not ON / OFF but has a numerical value or the like, the adjustment means sets a threshold value for threshold processing for the sensor output to the determination unit. Also good.

  By adopting such a configuration, in the present invention, since the support case is attached to the lighting fixture side and the main body is attached to the support case, the main body can be attached and detached. Since the main body is provided with the adjusting means and the mode setting switch in an exposed state, the user can change the mode setting of the dimming operation and the like as appropriate. Therefore, the user can set the mode field operation conditions of the dimming operation as needed, and the handling is easy and the mode setting can be easily changed.

  Since the device of the present invention is assembled on a one-to-one basis on a lighting fixture, that is, each of the electronic ballasts is equipped with a dimming sensor device that outputs a control signal for performing a dimming operation, the dimming of a large number of lighting fixtures provided indoors In the control, the dimming operation can be set individually. Therefore, it is possible to easily cope with a case where it is desired to change lighting conditions individually by changing the layout or changing the usage in the room.

  The determination means maintains the steady state lighting state without performing the dimming or extinguishing operation for a certain period even when the output of the sensor no longer satisfies the steady state lighting condition. When the state that does not satisfy the lighting condition continues for the certain period, the adjustment means has a function of performing dimming or extinguishing according to the operation mode, and the adjusting means has a function of setting the certain period It can also be.

  In this way, even when the output of the sensor fluctuates near the steady state lighting conditions, steady state lighting can be continued without repeating steady state lighting and dimming / extinguishing. it can.

  The main body may be provided with a display unit (LED) for displaying that the light control or light extinction is in progress. This is preferable because it can be easily understood whether the operation is normal or the light is dark / off during dimming or extinguishing, or whether it is a failure or the like. The display unit can be, for example, an LED or other lamp that is lit during dimming / extinguishing. In addition, when the lighting is in a steady state, the display unit may be turned off, or may be emitted in another form.

  If the mode change-over switch is selected to be turned off, the light may be turned off through a dimming step. By doing so, the dimming state continues, but the power consumption is suppressed compared to the steady state, but the power consumption continues. The effect is further increased.

  The main body has a cylindrical shape, the adjustment means and the mode change switch are mounted on a panel surface provided on a side portion of the cylindrical body, and a cylindrical portion for inserting the main body is provided in the support case. The main body can be detachably mounted.

  In addition, the support case has a cylindrical portion that accommodates the main body, and is divided into a two-divided outer cylindrical lower portion, an outer cylindrical upper portion, and a thread formed on the distal end side of the cylindrical portion covering the outer periphery of the cylindrical portion. When the nut ring is fastened with the outer cylinder lower part and the outer cylinder upper part attached to the cylinder part, the outer cylinder lower part and the outer cylinder upper part are separated from the cylinder part. It is set so that it cannot be detached, and an opening is formed in a size that fits the cylindrical portion in the reflector of the lighting fixture, and the lower part of the outer cylinder is attached to the opening from the back side of the reflector, and from the front side By mounting the outer cylinder upper part, the reflector can be configured to be sandwiched from the front and back by the outer cylinder lower part and the outer cylinder upper part.

  A lighting fixture of the present invention is a lighting fixture having a fluorescent lamp whose lighting is controlled by an electronic ballast having an inverter type configuration, and includes the above-described dimming sensor device, and the electronic ballast includes the dimming When a control command is received from the sensor device, it operates according to the received control command. When a control command from the light control sensor device cannot be received, it is input to the ON / OFF switch of the lighting fixture. Based on the configuration.

  In addition, as described above, the main body has a cylindrical shape, and in the configuration in which the main body is mounted on the cylindrical portion of the support case, the cylindrical portion and the outer cylindrical lower portion are fitted from the back side to the opening formed in the reflector of the lighting fixture, From the front side, the support case can be directly assembled to the reflector by fitting the upper part of the outer cylinder and the nut ring and sandwiching them from the front and back sides. Therefore, the device of the present invention can be installed on existing lighting fixtures.

  In this specification, “steady state” means, for example, when lighting is performed when it is necessary to turn on illumination (fluorescent lamp), for example, when the presence of a person is detected or when the surrounding brightness becomes dark (Brightness). In the embodiment, the output is 100%. However, in the present invention, it is not always necessary to set 100% to the steady state, and the output may be smaller than that to save energy from the steady state. The “dimming state” refers to a state in which the output is lower than that in the “steady state” lighting state and the lighting is dark. Therefore, if the steady state is 100% output, the light is dimmed if the output is lower than that, and if the steady state is 90% output, the light is dimmed if the output is less than 90%. Actually, it may be set in consideration of the energy saving effect and the brightness required in the dimming state.

  In the present invention, since the main body is mounted on the support case attached to the luminaire side, the user can easily attach and detach the main body. Since the adjustment means for the dimming operation and the mode changeover switch are exposed on the side surface (circumferential surface) of the main body, the user can remove the main body from the support case and operate the exposed adjustment means and the like. , You can easily change the dimming conditions and mode settings. Since the device of the present invention is attached to the lighting fixtures one-on-one, in the dimming control of the lighting fixtures provided in the room, the dimming operation can be individually set.

  Therefore, dimming control of a large number of lighting fixtures in the room is easy to install without the need for installation and wiring, and each lighting fixture can be set for dimming operation, and the setting can be changed appropriately. And has a high degree of freedom.

  Also, the support case is reflected by fitting the tube part and the lower part of the outer cylinder from the back side to the opening formed in the reflector of the lighting fixture, and fitting the upper part of the outer cylinder and the nut ring from the front side and sandwiching from the front and back sides. In the case of adopting a configuration that can be directly assembled to a plate, the device of the present invention can be installed on an existing lighting fixture. For this reason, if it is a lighting fixture with an electronic ballast, the existing lighting fixture can be reused as a light control lighting fixture, and there exists an advantage in a cost aspect. Of course, when the apparatus is attached to the lighting fixture from the beginning, the support case can be fixed to the lighting fixture by screwing or other various methods.

  FIG. 1 shows a preferred embodiment of the present invention. In this embodiment, the light control sensor device has a configuration in which a cylindrical main body 1 is provided with various sensors, mode changeover switches, adjustment means, a timer, a determination unit, and the like, and the main body 1 is detachably attached to the support case 2. . The support case 2 is attached to a lighting fixture (fluorescent lamp) with an electronic ballast and wired to an electronic ballast 50 having an inverter type configuration, and a control signal output from the main body 1 is transmitted to the electronic ballast 50 (relay). ).

  The main body 1 has a panel surface for setting and adjustment on the side of the cylindrical body, and a plurality (three) of terminals 3 for electrical connection are provided on the end surface on the side inserted into the support case 2. . A plurality of openings for various sensors and the like are provided on the exposed end surface of the main body 1 opposite to the end surface on which the terminals 3 are provided. As shown in FIG. 2, a circuit board is mounted (incorporated) in the main body 1, and a human sensor 4, an illuminance sensor 5, an LED for operation display 6, and a slide switch for mode switching are mounted on the board. 7. Components such as a variable resistor 8 for setting the sensitivity of the illuminance sensor 5, a rotary switch 9 for setting the timer, and a microcontroller (not shown) are arranged.

  That is, the dimming sensor device has a so-called microcontroller 10 as shown in FIG. 3, and the above-described human sensor 4, illuminance sensor 5, slide switch 7 (mode switching), and variable resistor 8 (sensitivity setting) A configuration that connects to the determination unit 11 and captures information signals from each of them, outputs a display signal from the determination unit 11 to the LED 6 (operation display), and a rotary switch 9 (timer setting) connects to the timer 12 and captures the setting signal It has become. The function of the determination unit 11 will be described later.

  FIG. 3 also shows the configuration of a lighting fixture with an electronic ballast. In this luminaire, lighting of the fluorescent lamp 51 is controlled by an electronic ballast 50 of an inverter type. The electronic ballast 50 has a general configuration of an inverter system, and a filter 53 connected to a power switch 52 is supplied with power, and a rectifier 54, a power factor controller 55, a logic control are provided on the output side of the filter 53. The generator 56 and the oscillator 57 are connected in order, and the output of the oscillator 57 is fed back to the logic controller 56 via the protection circuit 58 so that the lighting state of the fluorescent lamp 51 connected to the oscillator 57 is appropriately controlled. It has become.

  The electronic ballast 50 has a general inverter type configuration as described above. That is, basically, the lighting state of the fluorescent lamp is controlled in accordance with the operation of a power switch (ON / OFF switch or other switch) installed at a predetermined position on the wall surface performed by the user. Therefore, for example, the fluorescent lamp is turned on in a predetermined lighting state by turning on the power switch, and turned off by turning off the power switch. Further, switching between the steady state and the dimming state can be performed based on the operation of the power switch. For example, the power switch itself can send at least three types of commands of “steady lighting”, “dimming lighting”, and “off”, or even if the power switch is a simple ON / OFF switch. When the ON-OFF operation is repeatedly performed within a predetermined time (for example, twice), various measures such as lighting in a dimming state can be taken. Alternatively, a separate remote controller can be prepared, and the lighting state can be controlled by operating the remote controller with the power switch turned on. Since the operation of these switches and the control of the lighting state of the fluorescent lamp based on these switches are the same as those of inverter-type fluorescent lamps that are generally commercially available, a program (algorithm) implemented in the microcontroller 10 for realizing such processing ) Itself, it is only necessary to incorporate those well-known ones or the like, and a detailed description thereof will be omitted.

  Furthermore, the electronic ballast 50 mounted on the lighting fixture (fluorescent lamp) of the present embodiment is output based on the control content determined by the determination unit 11 that is a control means built in the main body 1 of the light control sensor device. A control signal is received, and the lighting state is controlled according to the control signal. As will be described later, since the control signal output from the microcontroller 10 of the main body 1 outputs three commands of “lighting in steady state”, “light control”, and “lighting off”, the electronic ballast 50 Has a function of recognizing the contents of the command of the control signal and turning it on (including extinguishing) according to the command.

  More specifically, in the present embodiment, the control signal (output according to the determination result of the determination unit 11) is input to the logic controller 56. Then, a predetermined lighting operation is performed based on the acquired control signal. That is, the logic controller 56 controls the output of the power factor controller 55 and intermittently controls the output of the oscillator 57. The output is continuous 100% output state (FIG. 4A) and temporarily stopped. The reduced output state {FIG. 4 (B), (C)} provided with the time T1, T2 is created. Therefore, the output can be appropriately controlled by changing the pause times T1 and T2, and dimming can be performed.

  Therefore, for example, assuming that the steady state is an output of 100% and the dimming state is a predetermined reduced output state (preset), when the control signal is “steady state”, the output of the power factor controller 55 When the control signal is “dimming”, the power factor controller 55 is operated so that the output of the power factor controller 55 is in a preset reduced output state. In the case of “off”, the output of the power factor controller 55 is 0%, that is, the oscillation is stopped. To repeat, when the setting of “steady state” is a predetermined reduced output state, when the control signal is “dimming”, the stop time is longer than the pause time in the “steady state”. It will be controlled to become.

  In addition, as described above, the electronic ballast 50 according to the present embodiment can control the lighting state including the dimming operation based on a command from a normal power switch. Even if the sensor device is out of order, the main body 1 is removed from the support case 2 or a connection failure occurs, the lighting control operation of the lighting fixture (fluorescent lamp) based on the normal power switch is guaranteed. The

  Next, the configuration of the main body 1 will be described in detail. The human sensor 4 includes, for example, an element that detects heat generation of a human body such as a thermopile / pyroelectric sensor. In the present embodiment, the detection sensitivity is fixed, and when a heating element having a certain temperature or higher is detected, a detection signal that a person is present in the monitoring region of the human sensor 4 is given to the determination unit 11. Composed. When receiving the detection signal, the determination unit 11 determines that it is lit in a steady state, and outputs a control signal associated therewith. Upon receiving this control signal (steady state), the electronic ballast 50 operates the output of the oscillator 57 to a predetermined value (for example, 100%), and turns on the output 55W. Of course, the wattage of the output is an example (the same applies hereinafter).

  The illuminance sensor 5 is composed of an element that detects brightness in the vicinity, such as a CdS cell. Based on the sensitivity set by the variable resistor 8, the illuminance sensor 5 outputs a detection signal when the surrounding brightness becomes darker than a certain level. This detection signal is given to the determination unit 11. When the determination unit 11 receives the detection signal from the illuminance sensor 5, the determination unit 11 determines that the light is lit in a steady state and outputs a control signal associated therewith. Upon receiving this control signal (steady state), the electronic ballast 50 operates so that the output of the oscillator 57 becomes a predetermined value (for example, 100%) and, for example, turns on the output 55W.

  The slide switch 7 sets an operation mode when not in a steady state. In the present embodiment, the slide switch 7 switches between a “light control mode” (dimming mode) and a “light-off mode” (standby mode). Thereby, for example, when the detection unit 11 cannot receive a detection signal from the illuminance sensor 5 (the ambient brightness is brighter than a certain level), the determination unit 11 determines that it is not necessary to light in a steady state, and the slide switch 7 A control signal corresponding to the set mode is output.

  The electronic ballast 50 that has received this control signal (the dimming mode / extinguishing mode) repeatedly executes the process of stopping the output of the oscillator 57 for a certain period in the dimming mode, for example, an output state of power 33W. To work. In the extinguishing mode (standby mode), the output of the oscillator 57 is turned off and the operation is performed so that the output state is 0 W. Actually, even in this extinguishing mode, the electronic ballast 50 is waiting to receive a control signal, so that a little standby power is generated.

  In the present embodiment, the determination unit 11 has a specification that allows the timer to be set by the rotary switch 9. The time set by this timer setting does not immediately shift to the dimming mode or the extinguishing mode when no one is present in the detection area of the human sensor 4 when it is lit in a steady state. This is the time for which the steady lighting state is maintained even if the person is not present. That is, if the determination unit 11 determines from the output signal of the human sensor 4 that there is no person, the determination unit 11 operates the timer 12 and waits for a time set by the rotary switch 9. Then, when a state in which no person is present continues even after such time has elapsed, a control signal for shifting to the dimming mode or the extinguishing mode is output. Of course, when the human sensor 4 detects a person during the time set by the timer 12, a steady-state control signal based on the detection of the human sensor 4 is output. Therefore, when the timer 12 is once cleared and then no one is present again, the timer 12 measures time for the set time again and maintains the steady state for the time. As a result, for example, when a person is wandering around the monitoring area of the human sensor 4 or returns immediately after going out of the monitoring area, the lighting state of the fluorescent lamp is adjusted to the steady state. A stable light emission state can be maintained by continuing the steady state without repeating light / extinguishing.

  In the present embodiment, this timer setting is used for control based on the output of the human sensor 4, but the present invention is not limited to this, and can also be used for control based on the output of the illuminance sensor. Conversely, the sensitivity setting of the human sensor 4 is fixed, but the detection sensitivity may be changed like an illuminance sensor.

  Moreover, the light control sensor apparatus is equipped with LED6 as mentioned above. The LED 6 is turned on when the determination unit 11 outputs a control signal for dimming mode / light-off mode, and is turned off when a control signal for steady lighting is output. Thereby, for example, when the lighting apparatus is turned off, the user can check whether the lighting apparatus is turned off due to a failure of the lighting apparatus itself, turning off the power switch, or the like based on a control signal from the light control sensor device. A distinction can be made easily. In the dimming mode, it is preferable that the fluorescent lamp is old or dark due to other factors, for example, since it can be seen at a glance whether the light is dimming due to the normal operation of the apparatus.

  Furthermore, in the above-described embodiment, an example in which two sensors, a human sensor and an illuminance sensor, are shown, but one may be used, or three or more may be used. Of course, sensors other than those described above may be used.

  Furthermore, it is preferable to provide the temperature sensor 15 in the above-described embodiments and modifications. The temperature sensor 15 detects ambient temperature and can be mounted on a substrate, for example. The specific control based on the output of the temperature sensor 15 is based on the detection signal based on the human sensor 4 and / or the illuminance sensor 5 described above when the temperature is low, to the condition for shifting from the steady lighting state to the dimming mode. Even if they match, control is performed so as not to immediately shift to the dimming mode but to shift to the dimming mode when the ambient temperature exceeds a certain level. In this embodiment, since the dimming mode is set to a very small wattage such as 33 W, a snake phenomenon may occur at a low temperature. Therefore, a function of shifting to the dimming mode after waiting for the temperature to rise to a constant temperature at which such a phenomenon does not occur is provided. Of course, such a configuration is not essential in the present invention. For example, if the lighting state in the dimming mode is not as small as 33 W and the wattage is set to an appropriate wattage that can be lit at a low temperature, the temperature sensor is not particularly required.

  The support case 2 has a cylindrical portion 20 into which the main body 1 is inserted, and the back side of the cylindrical portion 20 is an attachment base 21. The attachment base 21 is provided with a lock mechanism for electrical connection. The tube portion 20 is formed with a thread on the tip side, and is configured to be fitted with an outer tube 22 and screw the nut ring 23. In other words, when the main body 1 is mounted, when inserted into the cylindrical portion 20 of the support case 2 and turned, the terminal 3 is locked on the mounting base 21 side and the electrical connection is completed.

  Therefore, when the dimming sensor device is equipped, as shown in FIG. 5, the appearance of the luminaire becomes a form in which the ends of both the main body 1 and the support case 2 can be seen through the opening provided in the reflector 59 of the luminaire. Even after the appliance is assembled to the ceiling, the main body 1 can be easily attached and detached with a single touch.

  Also, three lead wires are output from the support case 2. One end of the lead wire is connected to a lock mechanism (such as a leaf spring) that electrically connects the support case 2, and a connector is connected to the other end of the lead wire. The electronic ballast 50 is detachably mounted using the connector. The breakdown of the three lead wires is two power supply lines and one control line. The control signal is supplied to the electronic ballast 50 through this control line. Further, power is supplied to the main body 1 from the electronic ballast 50 (lighting fixture) side via the power line, and it becomes a driving power source for sensors, LEDs, microcomputers, and the like attached to the main body 1.

  The outer cylinder of the support case 2 can be an attachment adapter, and the support case 2 can be directly assembled to the reflector 59 of the lighting fixture. In that case, as shown in FIG. 6, the outer cylinder of the support case 2 is divided into two parts, an outer cylinder lower part 24 and an outer cylinder upper part 25. An opening is formed in the chevron-shaped reflection plate 59 of the lighting fixture so that the cylindrical portion 20 of the support case 2 fits, and the cylindrical portion 20 and the outer cylindrical lower portion 24 are fitted from the back side of the reflective plate 59, and from the front side. The outer cylinder upper part 25 and the nut ring 23 are fitted together, and the reflection plate 59 is sandwiched from the front and back. Therefore, the present invention has an advantage that it can be easily attached to an existing lighting fixture later.

  According to such a configuration, the support case 2 is attached to the lighting fixture side, and the main body 1 is attached to the support case 2, so that the main body 1 can be attached and detached. Since the main body 1 has mode switching (slide switch 7), the mode setting of the dimming operation can be changed as appropriate. The mode setting can be changed by removing the main body 1 from the support case 2. In this case, the dimming sensor device according to the present invention is assembled one-to-one with the luminaire, and therefore the dimming operation can be individually set in the dimming control of the luminaire provided with a large number in the room.

  Therefore, dimming control of a large number of lighting fixtures in the room is easy to install without the need for installation and wiring, and each lighting fixture can set the mode of dimming operation as needed, and is easy to handle Therefore, the mode setting can be changed appropriately and the degree of freedom is high.

Moreover, the structure which fits the cylinder part 20 and the outer cylinder lower part 24 from the back side with respect to the opening formed in the reflecting plate 59 of a lighting fixture, and fits the outer cylinder upper part 25 and the nut ring 23 from the front side, and is clamped from the front and back. Thus, the support case 2 can be directly assembled to the reflection plate 59. Therefore, the light control sensor device according to the present invention can be easily assembled to an existing lighting fixture later, and energy saving and an appropriate lighting environment can be obtained by installing this device.
By the way, in facilities that require lighting even in the daytime, such as underground parking lots such as buildings, as shown in FIG. 7, a large number of lighting fixtures 60 are appropriately arranged to ensure a desired brightness.

  Therefore, the present invention is applied, and the luminaire 60 is provided in each parking space, and the approach is also provided at a predetermined interval. Of course, each luminaire 60 is equipped with a light control sensor device according to the present invention. Keep it. And since each lighting fixture 60 can set each operation mode, about the approach, it is set to always light at the electric power 55W in order to make the entrance always bright (the control by the sensor device of the present invention is not performed). . Thereafter, the mode changeover switch is appropriately set. Specifically, when there is no person, a dimming mode with power of 33 W and a light-off mode with power of 0 W are alternately set. In addition, each parking space is set to a light-off mode with an electric power of 0W.

  In such a setting, when there is no vehicle to enter, only the approach entrance side is bright, but when the vehicle enters, the human sensor 4 detects the engine heat. The lights are sequentially turned on in a steady state, and the vehicle is driven by bright lighting. And as the vehicle is advanced, the lighting fixtures 60 in the corresponding parking space are also brightly lit, and these remain brightly lit for the time set by the timer, so that a user who gets off the vehicle is bright when leaving the parking lot. The place can be walked, and after the timer time elapses, the luminaire 60 is turned off / dimmed to return to the original state, and then return to the original dark state again. As a result, for example, in an underground parking lot, it is possible to reduce power loss without inconvenience to the user by suppressing power loss caused by continually turning on lighting equipment all day long, and turning on lighting only when necessary Can do.

  In this case, each luminaire can be set in mode individually, and the setting can be easily changed by removing the main body 1 from the support case 2 and resetting it, and then mounting it again. Therefore, the lighting equipment of the facility can be optimized. And when the environmental conditions in the room change, readjustment is easy. Of course, there is no need for installation and wiring, and the setting change work can be done with one touch of each lighting fixture 60. Yes, this can be done by the administrator himself without asking the equipment maintenance technician.
