Description

TECHNICAL FIELD [0001] The present invention relates to a lighting apparatus having an electroencephalogram rhythm adjustment function,

The present invention relates to a lighting apparatus having a function of adjusting an electroencephalogram rhythm, and more particularly, to a lighting apparatus having an electroencephalogram rhythm control function The present invention relates to a lighting apparatus provided with such a lighting apparatus.

2. Description of the Related Art Generally, a lighting apparatus is installed in a ceiling or a wall to illuminate a certain area by irradiating light emitted from the lamp, and is widely used for securing a field of view in a dark room or at night. In recent years, in addition to providing a lighting function simply by using such a lighting apparatus, a color adjustment function capable of adjusting the color of the emitted illumination light to variously produce an atmosphere suitable for the user's sensibility, A dimming function for reducing power consumption by adjusting brightness, and the like have been disclosed.

However, the conventional lighting apparatus is driven so as to separately control the color hue of the illumination light and the illumination brightness, so that the illumination light of various colors is simply output from one lighting apparatus, and the color temperature and brightness of the illumination light are outputted at a certain ratio, There has been no development of a lighting apparatus equipped with an electroencephalogram control function for inducing brain wave change and activating brain function accordingly.

On the other hand, conventionally, when the user wakes up at an early morning time, an alarm function such as an alarm clock or a mobile is used. The alarm function outputs an alarm sound when the set alarm time is reached, and the user can wake up while listening to the alarm sound during sleep. However, in a quiet sleeping environment, a high-pitched alarm sound that occurs instantaneously awakens a user by awakening from sleep, and a biorhythm such as a hormone rhythm or a body temperature rhythm can not follow an abrupt change of body, resulting in internal dysynchronization. The fatigue and the stress are increased.

On the other hand, LEDs are widely used as lamps for lighting fixtures because of their advantages such as high efficiency, high lifespan, and low power. A conventional LED lighting apparatus includes a main body frame horizontally disposed and fixed to a ceiling of a room while being installed in a ceiling of a room, a LED panel having a plate shape and horizontally arranged in the main body frame, And a light diffusion plate mounted on the main body frame so as to cover the LED panel and transmitting the LED light emitted from the LED panel downward.

Here, in the case of the optical diffusing plate, the optical diffusion structure is configured to diffuse and transmit the LED light having high linearity. However, when the LED light is outputted with high luminance or the separation distance between the LED panel and the optical diffusing plate is narrow, The light emitted from the light source is glazed by the light source, and the brightness of the LED chip is relatively dark. Thus, shading occurs and the overall brightness of the illumination light is uneven. In addition, since the conventional LED lighting apparatus is installed so that the LED chip emits light directly below the LED panel horizontally arranged, there is a problem that expansion of the illumination range of the illumination light applied to the illumination area is limited.

In a conventional LED lighting apparatus, a reflector for reflecting light emitted from the LED chip in a downward direction to increase the light efficiency is used. When a reflective coating is applied to the reflector to form a reflective surface, Reflectivity can be realized, but the illumination light of the LED chip reflects (Veiling Reflection), so that the dot light of the LED chip shape is irradiated downward and glare is generated. Therefore, in order to reduce the glare due to the dot light, a matte coating may be applied to the reflection plate. However, in this case, the reflectance is lowered to 93% or less, thereby lowering the overall light efficiency of the LED light.

The power supply circuit 120 supplies power to the lamp unit 110. The power supply circuit unit 120 receives the commercial power and converts the power into a driving power for driving the lamp unit 110, And adjusts the power characteristics of the driving power according to the signal to supply the power to the lamp unit 110. Here, the adjustment of the power supply characteristic of the driving power source means controlling the current value, the voltage value or the frequency value PWM of the driving power source for controlling the color temperature and the illuminance of the lamp unit 110.

The power supply circuit 120 adjusts the supply ratio of the current supplied to the first light source unit 110a and the second light source unit 110b according to the control signal of the controller 130, And adjusts the voltage value in a state where the supply ratio of the current supplied to the first light source unit 110a and the second light source unit 110b is maintained to increase or decrease the illuminance of the illumination light to match the required illumination reference value have.
