Dimming control method for LED lamp and control equipment

The present invention relates to a dimming control method and a control device of a light emitting diode lamp, and in detail, the brightness of the light emitting diode while surrounding the light emitting diode while recognizing the external illuminance in the manner of being turned on again when the external illuminance is recognized through an illuminance sensor. By illuminating at the minimum illuminance value set in the range of 1-40% by, and recognizing the person moving through the human body sensor, the human body moves completely in the state that it illuminates at the maximum illuminance value of 100% Dimming control method and control device of the LED lamp which makes the user feel safe and comfortable when passing the night by lighting up the maximum illuminance for 10 to 60 seconds and gradually changing to the minimum illuminance value even though it is not detected by the sensor. It is about.

In general, it is well known that security lights are installed on the side of a road or on the side of a road to illuminate the darkness around them.

And in the case of the security light is composed of incandescent lamps, fluorescent lamps, LEDs, etc. in order to easily turn on and off so that it is automatically turned on at a predetermined time or installed to turn off at a predetermined time.

However, the lighting method of the conventional security lamp as described above has a problem in that when a person does not pass, it is lit with bright light, and when it is lit with bright light even when it is not relatively dark in the early evening or dawn, there is a problem of wasting electricity.

In addition, automatic entrance lamps are provided at entrance doors of apartments, buildings, etc., mainly to be turned on only when a person enters and exits for power saving lighting, and to be kept off.

The lamp detects infrared rays emitted from the human body using a superconducting sensor to turn the lamp on / off. The superconducting sensor reads only the change value of the infrared detection signal and controls the lamp to light for a predetermined time. Even if the passenger is waiting, the setting time is exceeded and the infrared detection change value does not occur, so the lamp is turned off.

Therefore, a person waiting at the entrance without completing entry and exit will turn on the lamp by changing his infrared detection value by shaking his arm or moving his or her body to restart the light when the light is turned off. should.

That is, a combination of a human body sensor (PIR sensor) and an illuminance sensor is a simple on / off type products that are turned on when the movement of an object is detected and turned off when there is no movement.

This is a product to save power by turning on the light only when there is movement of an object, or in this case, when a person enters a certain place, the sensor light should be turned on within the signal detection range under the sensor light so that the movement of a fast moving person is not detected. It can cause inconvenience to move.

In addition, since the incandescent light is turned on and off through a simple switch on / off, when the incandescent light is suddenly turned on in a very dark place, it causes eye fatigue due to a difference in illuminance.

Therefore, Korean Patent No. 10-2011-0027337 dated March 16, 2011 (Dimming device such as sensor using LED) has been proposed.
