For the power saving of such a lamp, a technology that combines an infrared sensor for detecting a person and an optical sensor for detecting an illuminance is introduced. However, such a technology has a disadvantage in that it is easily turned off if the human motion is large, and a complex sensor for detecting the presence of a human in real time by combining an ultrasonic sensor with an infrared sensor has been developed.

On the other hand, in the case of installing lighting lamps, such as fluorescent lights for the underground parking lot, it is necessary to adjust the illumination for power saving. To this end, a dimming ballast has been developed, and a separate control box for each lamp is used to control it directly by rotary control or mast control.

However, when dimming ballast is applied to fluorescent lamps and used for lighting of underground parking lot in large buildings such as apartments, it is not easy to control ON / OFF frequently due to the characteristics of fluorescent lamps, and various sensors and switchboards must be installed separately for each fluorescent lamp. As well as the cost of the furnace is greatly increased, a lot of wiring is entangled during electrical work, there is a problem that labor costs and construction period increases.

Recently, ordinary LED lights are installed instead of fluorescent lamps for electric savings, or dimming LED lights with dimming controls are installed to increase electric savings. At this time, in order to facilitate the dimming operation, the human body sensor and the control panel for signal transmission processing must be installed for each light, which is a great burden in terms of design, construction and operation.

1 is a block diagram of a wireless dimming converter for lighting control according to a preferred embodiment of the present invention, Figure 2 is a block diagram of a lighting control apparatus including a wireless dimming converter for lighting control of FIG.

Wireless dimming converter for lighting control according to a preferred embodiment of the present invention, referring to Figures 1 and 2, the sensor unit 10, the illuminance sensor 20, the illuminance sensor circuit unit 22, the Zigbee circuit unit 24, dimming Control unit 30, LED driver circuit unit 32, LED lamp 34, power supply unit 50, DC-DC converter 52, AC output connector 54, DC output connector 56, remote control 60 , A setting switch 70, a group setting unit 80, and a microcontroller 100.

The sensor unit 10 detects the presence and / or movement of a person or an object in a space in which light control is to be performed. The sensor unit 10 includes an infrared sensor unit and a microwave sensor unit.

The infrared sensor unit includes an infrared sensor 12 and an infrared sensor circuit unit 14, and the microwave sensor unit includes a microwave sensor 16 and a microwave sensor circuit unit 18.

The infrared sensor 12 detects a physical quantity or a chemical quantity such as temperature, pressure, radiation intensity, etc. by using infrared rays, and converts it into an electrical quantity capable of signal processing. Infrared has a longer wavelength than visible red light in the electromagnetic spectrum and a shorter wavelength than microwaves, and has a wavelength of about 0.75 μm to 1 mm. Infrared sensors have an active type that detects changes caused by blocking light by firing infrared rays by itself, and a manual type that reads only the change of infrared rays received from the outside without self-luminous.

The infrared sensor circuit unit 14 converts the signal detected by the infrared sensor 12 into data and transmits the data to the microcontroller 100.

The microwave sensor 16 generally uses microwaves to detect the presence and / or movement of a person or object. Microwaves are strong in directivity, transmit radio waves only in certain directions, enable long-distance transmission with less power, and have a wider range of radio waves.

The microwave sensor circuit 18 converts the signal detected by the microwave sensor 16 into data and transmits the data to the microcontroller 100.

The illuminance sensor 20 detects a current illuminance value and transmits it to the illuminance sensor circuit 22.

The illuminance sensor circuit 22 converts the signal input from the illuminance sensor 20 into data and transmits the data to the microcontroller 100.

The Zigbee circuit unit 24 transmits a signal received from the sensor unit 10 to the microcontroller 100. In addition, the Zigbee circuit unit 24 transmits a signal received from the remote controller 60 to the microcontroller 100. The ZigBee circuit unit 24 performs wireless communication between adjacent ZigBee circuit units and performs illumination control through ON / OFF command and dimming for each group.

For example, when 16 lighting control wireless dimming converters are installed in an underground parking lot, ZigBee circuit units embedded in each lighting control wireless dimming converter perform wireless communication. Each lighting control wireless dimming converter is assigned a unique ID. When a total of 16 are classified into four groups, adjacent four lighting control wireless dimming converters are assigned with a first group and may be synchronized with each other. Wireless dimming converter for the light control synchronized with each other can be uniformly performed ON / OFF and illumination control of the lighting.

Meanwhile, a second group may be assigned to the wireless controllable dimming converters to which the first group is assigned and the four wireless controllable dimming converters adjacent to each other, and the wireless controllable dimming converters belonging to the first group and the second group are Zigbee. When the object or person moves from the first group to the second group by communicating a control command through the circuit unit, the first group transmits an ON command to the second group.

The dimming control unit 30 receives a dimming command from the microcontroller 100. The dimming command means to increase the illuminance by the ON command when the currently measured illuminance value is low compared to the preset threshold illuminance value, and to turn off the OFF command when the currently measured illuminance value is high compared to the preset threshold illuminance value. Means the illumination control command to reduce the illuminance through.

For example, the microcontroller 100 transmits an ON command to the dimming control unit 30 when the current illuminance value measured by the illuminance sensor 20 is lower than a predetermined threshold illuminance value. The dimming control unit 30 receiving the ON command transmits the ON command to the LED driver circuit unit 32.

The LED driver circuit part 32 is electrically connected to the dimming control part 30 and the LED lamp 34. The LED driver circuit unit 32 supplies power to the LED lamp 34 with a size corresponding to the dimming command received from the dimming control unit 30. For example, when the LED driver circuit unit 32 receives an ON command from the dimming control unit 30, the LED driver circuit unit 32 may supply power of an appropriate size to the string of the LED lamp, so that the illumination of the LED lamp 34 may exceed a predetermined threshold illuminance value. Make sure In addition, when the current illuminance of the LED lamp 34 is unnecessarily high, the dimming control unit 30 receives a dimming command from the microcontroller 100 to supply power of a lower size in order to save power. ), And the LED driver circuit 32 supplies power to the LED lamp 34 with a size corresponding to the received dimming command.

The plurality of LED lights 34 are connected in series or in parallel to provide lighting to public places such as underground parking lots and stairs by being turned on or off at appropriate brightness depending on the power applied from the LED driver circuit 32.

The power supply unit 50 receives AC power and converts it into DC power using a rectifier circuit. For example, the power supply unit 50 receives AC 220V power and rectifies and converts the power into DC power.

The DC-DC converter 52 is a portion that lowers the high power supplied from the power supply unit 50 to a power that can be supplied to peripheral circuits including the microcontroller 100.

The AC output connector 54 and the DC output connector 56 supply power to the microwave sensor 16 when the microwave sensor unit is mounted on the outside. When the output of the AC power is required, the load is connected to the AC output connector 54, and when the output of the DC power is required, the load is connected to the DC output connector 56.

The remote controller 60 transmits control commands including various settings and ON / OFF commands such as LED lights to the Zigbee circuit unit 24. To this end, the remote control 60 is also equipped with a communication module for Zigbee communication. The remote controller 60 is used to manually set the lighting control.

The setting switch 70 is a part for setting settings including ON time (time to turn on the LED lamp), dimming level, and the like. Items set by the setting switch 70 are stored in the microcontroller 100 and performed.

The sensor ID setting unit 80 groups the sensor unit 10 and sets the same ID by synchronizing the grouped sensor units. For example, as shown in FIG. 1, the entire sensor unit may be classified into ID_1, ID_2, ID_3, and ID_4, so that the sensor units corresponding to each unique ID may be synchronized with each other to uniformly control ON / OFF and dimming levels. The sensor ID setting unit 80 may be implemented as a DIP switch, but is not limited thereto. Items set in the sensor ID setting unit 80 are stored in the microcontroller 100 and performed.

The microcontroller 100 reads the ID of the sensor unit from the sensor ID setting unit 80 (first step), analyzes the signal received from the ZigBee circuit unit 24, and matches the ID among the IDs read in the first step. If there is an ID that matches the search result of the second step, the search command (step 2) transmits an ON command to the dimming control unit 30 (step 3). After transmitting the ON command, the microcontroller 100 transmits a command to the dimming control unit 30 to gradually decrease the brightness after the set time elapses (step 4).

The microcontroller 100 receives the conversion value of the illuminance sensor from the illuminance sensor circuit 22 to determine the current illuminance state, and compares the dimming control unit when the current illuminance is lower than the threshold illuminance value. Send the ON command to (30). On the contrary, when the current illuminance is higher than the threshold illuminance value, the OFF command is transmitted to the dimming control unit 30.

In addition, the microcontroller 100 transmits a command received from the Zigbee circuit unit 24 to the dimming control unit 30 so that the ON / OFF and illumination control of the illumination can be performed. For example, when the sensor unit belonging to ID_1 detects the presence and / or movement of an object or person, the microcontroller 100 reads ID_1, which is an ID of the sensor unit, from the sensor ID setting unit 80 (first step), and the Zigbee circuit unit. Analyze the signal received from (24) (step 2). At this time, when the signal from the ZigBee circuit unit 24 sensed by the sensor unit belonging to ID_1, the microcontroller 100 searches for ID_1 ~ ID_4 and determines that there is a matching ID (ID_1). The microcontroller 100 transmits an ON command to the dimming control unit 30 (step 3), and gradually transmits a brightness reduction command to the dimming control unit 30 after the set time has elapsed (fourth). step).

One control panel 200 is provided for each floor of a space (for example, an underground parking lot) to perform lighting control. The control panel 200 collects data including lighting time and power consumption of the LED lighting lamp from the plurality of wireless controllable dimming converters.

The central computer 300 is installed in the management room to receive data from the control panel 200 to build a database, and to transmit a user's operation command to the control panel.

The lighting control device for power saving can be configured as follows.

First, to implement an integrated wireless dimming converter consisting of a microwave sensor, an infrared sensor, a dimming ballast, a Zigbee communication module. As such, when the sensor, the dimming ballast, and the Zigbee communication module are integrated, the wiring problem is solved when the lighting is installed in a space such as an underground parking lot, and the labor cost, equipment, and material cost are reduced. In addition, it is desirable to implement the microwave sensor and the infrared sensor to be detachable so that it can be inserted only where necessary. In addition, if the integrated type is implemented, it is not necessary to install a separate control panel for each converter, and only one control panel is installed in one space (each floor in the case of underground parking lot). We can collect enough.
