Lighting System with Dimming Control Function for adaptive night vision {Lighting System with Dimming Control Function}

The present invention relates to a lighting system having a night vision adaptive dimming control function, and more particularly, when a person wakes up for a specific purpose during night sleep, by dimming control of the lighting brightness of the light to help the human body comply with the luminous sensation while others sleeping in the same space. It relates to a lighting system having a night vision adaptive dimming control function capable of effectively preventing disturbance of sleep by light.

Recently, as the quality of life improves along with environmental factors, interest in developmental improvement for a healthy life physically, mentally, and socially is increasing, and interest in healthy life begins with the improvement of our diet, lifestyle and residential environment. Has become.

In particular, lighting in a residential environment is essential to us, and it plays a role in providing visual assistance and work environment so that we can see the necessary information and making the indoor atmosphere comfortable. It has been found that it has an influence on the psychological and mental aspects of the child, forming a close relationship between lighting and a healthy life. Accordingly, there is a need to develop a lighting system capable of providing an appropriate amount of brightness suitable for the purpose and function of a residential space.

In such a lighting system, LED (Light Emitting Diode) lighting, which is a representative lighting source in recent years, has a significantly longer life than conventional lighting (halogen lamp, fluorescent lamp, incandescent lamp, etc.) and energy consumption is economical (e.g., 80% compared to incandescent lamps, 30 compared to fluorescent lamps). %) and eco-friendly. In particular, impulsive driving is possible, color reproducibility is more than 100%, and brightness and color temperature can be arbitrarily changed by adjusting the amount of light of red, green, and blue LEDs. It is in the limelight as a source of illumination.

Here, the lighting system using LEDs must constitute a complex circuit according to various types of lighting. In particular, for dimming control of lighting, a separate signal line for dimming control of lighting is required through an external controller. In terms of design, there was also a problem that efficiency was inferior.

As a conventional technique disclosed to solve the above problems, Korean Patent Publication No. 1292067 (2013.07.26.) converts AC power into DC power, and varies the input voltage of the converted DC power to a lighting device. A variable power supply to supply to; And a lighting device for performing dimming control on at least one LED using a DC power supplied through the variable power supply unit, wherein the lighting device includes at least one LED; A non-isolated power supply circuit for receiving and supplying DC power required for the operation of the LED dimming control circuit; An LED dimming control circuit that receives DC power from the non-insulated power circuit, generates a PWM control signal to enable dimming control for the LED, and transmits it to the LED dimming power circuit; And an LED dimming power circuit that receives DC power from the variable power supply and supplies DC power for driving the LED according to the PWM control signal received from the LED dimming control circuit. An LED dimming control system that can be easily configured and has high reliability is known.

However, in the case of the above-described conventional technology, general indoor lighting implements an illuminance between 150 and 1,500 lux. Even if the lighting system in an indoor space is dimmed, a fade in/out of 10 to 100% of the corresponding lighting is achieved. Since only dimming control is possible, the minimum illumination level of the lighting can be realized only up to 15~150 lux, so when you need to wake up in an emergency while the lights are completely turned off at night (e.g., when going to the bathroom or taking care of a child) When evacuating due to an earthquake or fire), it is difficult to realize human-centered observing observing movements due to instantaneous lighting, which is a discomfort and glare that temporarily fails to perform the visual perception function due to the level of individual pupil opening. There was a problem that it caused a decrease in circadian rhythm while causing adverse effects on health, such as sleep disorders and insomnia, by being active in a physically unadapted state.

In addition, there is a problem in that the conventional lighting system by dimming control interferes with the sleep of others because the lighting of one person wakes up while sleeping in a space of a family unit.

The lighting controller 20 includes a time setting unit 21 configured to set and store a specific night time zone, that is, a user's sleeping time zone, for dimming control in a night dimming control mode at night.

For example, when the user sets the bedtime from 11 o'clock (PM) to 6 o'clock (AM), the time in the night time zone for the night dimming control mode from the lighting controller 20 to the time setting unit 21 Since the setting is saved from 11 o'clock to 6 o'clock, the night dimming control mode can be performed only in the corresponding time zone.

The lighting controller 20 is configured to apply a flashing signal to the night dimming control mode including a general flashing signal to the LED lighting 10 because the power switch is turned on/off (OFF).

In addition, in the lighting controller 20, it is possible to configure a motion detection unit 23 that detects a specific movement so as to determine the sleeping state of a person in the lighting area.

The motion detection unit 23 transmits a detection signal to the lighting control unit 30 as it detects motion, but the LED lighting 10 is only turned on when the power switch of the lighting controller 20 is turned on. It is also possible to configure the lighting control to be controlled, irrespective of the on (ON) / off (OFF) state of the power switch of the lighting controller 20, in the night dimming control mode situation, in the motion detection unit 23 When a detection signal is input, it is also possible to configure the LED lighting 10 to be always lit.
