Description

Luminaire control system for controlling area luminaires by a single switch

The invention relates to a control system, and more particularly to a luminaire control system for controlling a regional luminaire by a single switch.

As the problem of the greenhouse effect becomes more and more serious, the climate of the earth's environment changes and the temperature rises, causing the outdoor environment to be hot and hot. Therefore, people have turned on the air conditioner indoors to keep the environment cool and comfortable to facilitate office or life. However, a large number of air conditioners turn on the electricity. The increase in the volume has caused the power company's power reserve capacity to decrease. In severe cases, the power company's power supply cannot be overloaded and power is cut off. Therefore, the government will provide a power-saving incentive to reduce the electricity consumption by reducing the electricity consumption. Save electricity.

However, the high ambient temperature forces people to not turn on the air conditioner. Therefore, it is necessary to reduce the power consumption in other directions to reduce the burden on the power company. Take Taiwan as an example. At present, 10% to 13% of the total electricity consumption in Taiwan comes from lighting power. If it can save lighting power for some time, it will reduce the burden on the power company and increase the backup capacity.

When the power consumption reaches a peak and the power company's backup capacity is insufficient, the power company will issue a Demand Response to notify major companies, office buildings and other contacts, in the hope that the other party can reduce and reduce power consumption. The contacts of major companies and office buildings will turn off or reduce the power consumption of the electrical equipment that can reduce the power consumption. For example, the luminaires will switch the luminaire to a low-light program to reduce power consumption. However, the existing luminaires control the brightness by switching a corresponding switch, so that multiple luminaires have multiple switches, which requires a lot of manpower to be arranged to go to different areas of the luminaire, to change the brightness of each luminaire one by one through each switch. Not only is it a waste of time, it can't respond to the demand response instantly, and it needs to be configured more than human resources to waste resources.

In view of the above situation, another lamp in the prior art is provided with a communication unit for transmitting a control signal to the communication unit through the remote end to control the brightness of the lamp, although the lamp eliminates the switch to each lamp. Before the time, and reduce the time to switch the brightness of the luminaire, however, each luminaire must be equipped with a communication unit, which not only causes the cost of replacing the luminaire, but also must be switched by the remote one in the control. In order to change the brightness of the luminaire, it is still unable to respond effectively to the demand response.

In view of the above problems in the prior art, the present invention provides a luminaire control system for controlling a regional luminaire by a single switch, which can uniformly change the brightness program of all luminaires by a single switch, and does not need to add an additional luminaire to each luminaire. The communication unit is installed, thereby achieving the purpose of quickly changing the brightness of the lamp and reducing the cost.

The technical means adopted for achieving the above purpose is to enable the foregoing luminaire control system for controlling the area luminaire by a single switch, comprising: a main switch for connecting to a power supply circuit for outputting more than one set of switching signals, the group The switching signal includes a signal and an opening signal of the adjacent output. The plurality of lamps are electrically connected to the power circuit and are electrically connected to the main switch. The lamps include: a lighting module; a memory unit Storing a step dimming program and a brightness resetting program; a controller electrically connecting the memory unit, the lighting module and the main switch; and each of the controllers receives the adjacent two groups of the main switch connection output Switching the signal, and determining that the interval between the two sets of switching signals falls within a step dimming time interval, respectively performing the step dimming program to control the corresponding one of the lighting modules to change the lighting brightness in a stepwise manner; When each controller successively outputs adjacent two sets of switching signals according to the receiving of the main switch, and determines the interval between adjacent two sets of switching signals When the interval is within a reset time interval, the brightness resetting program is separately executed to control the corresponding one of the light-emitting modules to be uniformly changed to the same light-emitting brightness.

According to the above configuration, since the lamps have a step dimming program, the signal can be switched at each output by a single main switch, that is, the adjacent signal and the signal are alternately output. In other words, the main switch is switched from on to off quickly, and then switched back on (ON to OFF to ON), and the lamps can be controlled to change the brightness of the light in a stepwise manner for convenient use. When the power company transmits a demand response, the main switch alternately outputs two sets of switching signals, and when the interval time of the group switching signals exceeds the set value, the lamps can be uniformly reset to the same brightness. In this way, the demand response sent by the power company can be quickly reacted, so as to quickly change the brightness of the lamp, thereby reducing the power consumption and saving the cost.

The foregoing is merely an example and is not limited.

Each time the controller 11 executes the step dimming program, the corresponding one of the illumination modules 12 is driven to change the illumination brightness in a stepwise manner, such as changing from the first illumination brightness mode to the second illumination brightness mode. The second illumination luminance mode is changed to the third illumination luminance mode to achieve the function of step dimming, wherein the order of changing the illumination luminance is merely an example and is not limited.

In addition, when the controllers 11 simultaneously execute the brightness resetting program, the corresponding lighting module 12 is controlled to be reset to the same lighting brightness mode, for example, to the third lighting brightness mode, but not Limited. For example, in the operating room, since the light cannot be reset to an excessively dark illumination mode, all operating rooms in the hospital can be reset to a minimum of 75%, such as the second illumination mode, but not limited thereto. Use the environment and location to set the brightness mode after brightness reset.

The controller 11 can be a programmable controller, and the program of the controller 11 can be externally modified to modify the order of changing the brightness mode of the step by step, such as changing from the first brightness mode to The fifth illumination brightness mode is sequentially changed to the fourth illumination brightness mode, the third illumination brightness mode, and the second illumination brightness mode to return to the first illumination brightness mode; or the first illumination brightness mode is changed to The second illumination brightness mode is sequentially changed back to the first illumination brightness mode. In addition, you can modify the brightness reset program to reset to any kind of brightness by externally modifying the program.

When the controller 11 determines that the interval between successively receiving the two sets of switching signals falls within a step dimming time interval (Ts), the controller 11 executes the step dimming program to drive the lighting module. 12 changes the brightness of the light in the step direction. The controller 11 determines whether the interval time between receiving the two sets of switching signals falls within the step dimming time interval (Ts), and is when the controller 11 receives the two sets of switching signals. After the signal 202, the controller 11 reads the illumination duration from the memory unit 13, and determines whether the illumination duration falls within the step dimming time interval (Ts), and if so, controls the corresponding one.

The reset time interval (Tr) can be set to 10 seconds to 30 seconds. The controller 11 determines whether the interval between the two sets of switching signals falls within the reset time interval (Tr), and is the signal 202 of the last group of switching signals when the controller 11 receives the two sets of switching signals. After that, the controller 11 reads the illumination duration from the memory unit 13 and determines whether the illumination duration falls within the reset time interval (Tr). If so, the corresponding illumination module 12 is uniformly controlled. Changing to the same illumination brightness, if not, the controller 11 further intervals whether it falls within the step dimming time interval (Ts), and if so, controls the corresponding one of the illumination modules 12 to change the illumination in the step direction. Brightness, if not, the controller 11 does not operate.

In addition, each of the memory units 13 further stores a lock program. When the controller 11 executes the brightness reset program, the lock program is executed to lock the current brightness mode of each of the lamps 10. The illumination brightness mode of each of the lamps 11 is prevented from being erroneously changed.

Referring to FIG. 3C together, when the locking program of each of the lamps 10 is to be released, the main switch 10 is switched to alternately output two sets of switching signals to the controllers 11, and each of the controllers 11 determines adjacent Whether the interval between the two sets of switching signals falls within an unlocking time interval (Tu), and if so, the controller 11 releases the locking of changing the brightness so that the main switch 10 can change the brightness of the lamp 10, and if not, the control The device 11 does not unlock, and the method of determining whether the interval time falls within the unlocking time interval (Tu) is the same as the manner of determining the step dimming time interval (Ts) and the reset time interval (Tr).

The time interval of the step dimming time interval (Ts), the time interval of the reset time interval (Tr), and the time interval of the unlocking time interval (Tu) are different, and in this embodiment, the unlocking is performed. The time interval (Tu) is greater than the reset time interval (Tr) is greater than the step dimming time interval (Ts) (Tu>Tr>Ts), but is not limited thereto, and the setting may be changed according to the use condition.
