ILLUMINATING CONTROLLING APPARATUS AND METHOD FOR EMITTING LIGHT ACCORDING TO POWER IN DIFFERENT GRADES}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting control device and a lighting control method, and more particularly, to a lighting control device and a lighting control method for controlling to emit light according to a differential power (differential voltage).

Lighting devices such as fluorescent or incandescent lamps or light emitting diodes (LEDs) are mainly composed of dichotomous operation of ON / OFF switch according to on / off switch.

As an example of a lighting device equipped with a fluorescent lamp, in the case of a 20-watt fluorescent lamp, when the user turns on the switch through the switch, the fluorescent lamp emits light at 20 W, and does not emit light at a power of 10 W or 5 W or less. Lighting devices equipped with incandescent bulbs are also not configured to emit light with power lower than their rated power, such as 40 W, 60 W or 100 W.

By the way, in places where there are not many traffic, such as a person or a vehicle, or the power of the maximum rated value is not required, waste of electric power will increase more than necessary. For example, in an underground parking lot where a vehicle is not frequently moved, a lighting device such as a fluorescent lamp is always turned on, but a lot of electricity is wasted when compared to the movement of a vehicle or a person. In addition, there is a problem that there is a waste of electricity anywhere where there is not much movement of people or vehicles, such as a large logistics warehouse where there is not much movement of people or street lamps of narrow alleys, but where constant lighting is required.

In this case, the control unit may be configured to automatically turn off the LED lamp by using the illuminance sensor during the day, and to automatically turn on the LED lamp at a power of 5W by using the illuminance sensor at night. The controller controls the power supply to supply 5 W of power to the LED lamp at night when the LED lamp is 20 W, and the power supply unit for a predetermined time when ambient movement is detected by the sensor unit. It may be configured to control to supply 20 W of power to the LED lamp, and after a predetermined time, the power supply unit controls to supply 5 W of power to the LED lamp again to implement a nighttime emergency light function.

According to another aspect of the present invention, there is provided a lighting control method for controlling to emit light according to differential power, the power supply of supplying power of a first power value to an LED lamp at all times, and the LED lamp of the supplied first power value of Emitting light according to the power, sensing the peripheral motion by the sensor unit, and when the peripheral motion is sensed by the sensor unit, the power supply unit controls the power of the second power value for a predetermined time according to the control of the controller.

Hereinafter, preferred embodiments according to the present invention will be described with reference to the accompanying drawings.

1 is a block diagram of a lighting control device for controlling to emit light according to the differential power according to an embodiment of the present invention.

Referring to FIG. 1, an illumination control device 100 (hereinafter, referred to as an “illumination control device”) controlling to emit light according to differential power according to an embodiment of the present invention includes a power supply unit 110 and a sensor unit 120. ) And the controller 130.

The lighting control device 100 is configured such that rated power is consumed only when the sensor unit 120 detects movement of a person or a vehicle in a place where constant lighting is required, such as an underground parking lot or a warehouse, and at other times, the rated power is always used. By being configured to consume less power, it reduces power consumption and extends the life of the LED lamps. Here, the LED lamp may be configured to always emit light according to the power supplied. That is, the LED lamp is configured to always emit light regardless of the day and night in the light control device 100 installed in an underground parking lot or a large logistics warehouse. The LED lamp may be configured as any one of a fluorescent, incandescent, mercury, and light emitting diode (LED) element as an LED lamp for illumination. All other lighting LED lamps may be applied. Hereinafter, the detailed configuration will be described.

The power supply unit 110 may be configured to supply power of the first power value or the second power value to the LED lamp. The power supply unit 110 is a component for converting and supplying general AC power to DC power, and is configured to supply power of two different power values to the LED lamp, unlike the conventional art. Thus, as the power supply unit 110 supplies power of different power values to the LED lamp, the LED lamp emits light with different brightness. More specifically, the power supply unit 110 controls to supply the power of the first power value lower than the second power value or the second power value which is the rated power value of the LED lamp.

The sensor unit 120 may be configured to detect peripheral movement. The sensor unit 120 detects movement of a person or a vehicle in a predetermined area around the place where the light control device 100 is provided. This is to allow the power supply unit 110 to supply power of different power values according to the detection of the sensor unit 120. In other words, when there is a person or a vehicle, the LED lamp emits brighter light, and the LED lamp emits darker than usual.

The sensor unit 120 may be configured as a human body sensor PIR or an illumination sensor CDS. The human body detecting sensor is a sensor for detecting a human movement, and the illuminance sensor is a sensor for distinguishing day and night. Accordingly, it may be configured to operate differently.

On the other hand, the controller 130 may be configured to automatically turn off the LED lamp by using the illumination sensor during the day, and to automatically turn on the LED lamp with a power of 5W by using the illumination sensor at night.

In addition, when the LED lamp is 20W, the controller 130 controls the power supply unit 110 to supply 5W of power to the LED lamp at night, and when the surrounding motion is detected by the sensor unit 120, the power supply unit. Control 110 to supply 20 W of power to the LED lamp for a predetermined time, and after a predetermined time to control the power supply 110 to supply 5 W of power to the LED lamp again to implement the night emergency light function. Can be configured. That is, the controller 130 controls the supply power of the power supply unit 110 by receiving the detection signal of the sensor unit 120 or referring to whether the sensor unit 120 is detected. If there is a detection of the sensor unit 120, the power supply of the power supply unit 120 is set to a second power value for a predetermined time, and the power supply of the power supply unit 120 is always present when there is no detection of the sensor unit 120. Is set to the first power value. Here, the second power value is the rated power value of the LED lamp, which will be 20 W for the fluorescent lamp of 20 W rated power. The first power value is lower than the second power value, and may be, for example, 5 W, 10 W, or the like. In the case of an incandescent lamp, the rated power which is the second power value may be 40 W, 60 W, 100 W, or the like, and the first power value may be set to 10 W, 20 W, 30 W, or the like accordingly. As such, when the peripheral part is detected by the sensor unit 120, in particular, the human body sensor, the controller 130 may change the power value of 5 W into a power value of 20 W at all times. Accordingly, the light control device 100 emits light a little dark at all times, but brightly emits light at the original rated power value when the vehicle or a person is in the peripheral region of the light control device 100. In addition, if a person is not detected through the human body sensor may be configured to reduce to 5 W after 10 seconds. In another embodiment, once a movement of a person or a vehicle is detected, the controller 130 may be configured to change the power value for a predetermined time as appropriate for at least 5 seconds or 30 seconds. The controller 130 preferably includes a timer 131 separately. After the control unit 130 controls the power supply unit 110 to supply power to the second power value for a predetermined time, the power supply unit 110 is configured to control to supply power to the first power value, which is always the power value again. Can be. On the other hand, in the case where the sensor unit 120, in particular, the illuminance sensor and the human body sensor operate together, the controller 130 sets the power value of 5 W at night, and sets it to 20 W when a person is detected. If not detected, the power can be reduced to 5 W after 10 seconds. In addition, it may be configured to turn on at 5 W at night and then turn on brightly at 20 W when a person is detected, and then reduce the power to 5 W after 10 seconds if no person is detected.

In this way, by lowering the power of the regular lighting other than necessary when the lighting control device 100 is installed in a place where the regular lighting is required, it is possible to reduce the power consumption, and to extend the life of the LED lamp such as fluorescent or incandescent. When used on shared stairs, it can also function as an emergency light. In particular, it is possible to reduce the environmental pollution due to power waste, and also to prevent the environmental pollution by increasing the life of the LED lamp that affects the environmental pollution during disposal such as fluorescent or incandescent lamp.

2 is a flowchart of a lighting control method of controlling to emit light according to differential power according to an embodiment of the present invention.

Referring to FIG. 2, the power supply unit 120 supplies power of a first power value for constant lighting to an LED lamp (S110).

Then, day or night is detected using the illumination sensor (S120). At this time, at night, the LED lamp emits light at all times according to the power of the first power value (S130). However, the LED lamp is turned off during the day (S132). Here, the first power value may be configured to a power value lower than the rated power value of the LED lamp. This is because the first power value is a low power value for reducing power consumption.

Next, the sensor unit 120 continuously detects the movement of the surroundings (S140). When the lighting control device 100 is installed in an underground parking lot or a narrow alley where the human race is rare, the sensor unit 120 detects the movement of a vehicle or a person.

The controller 130 determines whether there is a movement of a person or a vehicle by receiving a detection signal from the sensor unit 120 or referring to whether the sensor unit 120 is detected (S150).

At this time, if not detected, the sensor unit 120 continues to detect. However, when it is determined that the sensor unit 120 detects the peripheral movement, the power supply unit 110 supplies the power of the second power value to the LED lamp for a predetermined time under the control of the controller 130 (S160). Here, the second power value is the rated power value of the LED lamp, for example, 20 W for a 20 W fluorescent lamp, and 40 W for a 40 W incandescent lamp.

The LED lamp emits light for a predetermined time according to the second power value (S170). In other words, when there is surrounding movement, the original lighting is bright.

The controller 130 measures a predetermined time using the timer 131, and determines whether the predetermined time has elapsed (S180).

When a predetermined time has elapsed, the controller 130 controls the power supply unit 110 to supply power to the first power level at all times, and the power supply unit 110 supplies power of the first power value to the LED lamp (see FIG. S110). Thereafter, step S120 and below S170 are repeatedly performed continuously.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined in the appended claims. It will be possible.
