However, the present invention is not limited thereto. A lighting device having a function of controlling a light source through a radio wave based sensor according to the present invention can be applied to a lighting device installed at a predetermined height from the ground through a lighting device for supporting a wall or a support post or the like, It can be applied to all kinds of lighting fixtures.

1, a lighting device 100 (hereinafter referred to as a "lighting device") having a function of controlling a light source through a radio wave-based sensor according to an embodiment of the present invention includes a case 110, a cover 120, A sensor 130, and a light source 140. [ In addition, the lighting device 100 according to an embodiment of the present invention may further include a controller 150 and an illuminance sensor 160.

The case 110 forms the overall contour of the lighting device 100 and at the same time forms an installation space for the radio wave sensor 130 and the light source 140. The case 110 thus has an opening 111 are formed.

The cover 120 is coupled to the case 110 in a state of blocking the opening 111 of the case 110 from the outside, and is formed of a light-transmitting material.

The radio wave sensor 130 is installed inside the case 110. The radio wave sensor 130 includes a radio wave transmitting part 131 so that the radio wave transmitted from the radio wave transmitting part 131 is absorbed and reflected by a human body or an object, A change in the state of propagation of the radio wave by the radio wave sending unit 131 is detected.

In this embodiment, it is exemplified that the radio wave sensor 130 detects the presence or motion of a human body or an object through a phase change when the radio wave of the radio wave transmitting unit 131 is transmitted due to the absorption or reflection of radio waves of a human body or an object , But the present invention is not limited thereto.

The light source unit 140 is installed inside the case 110 and the operation of the light source unit 140 is automatically controlled based on the detection signal of the electric wave sensor 130.

That is, the light source unit 140 is turned on / off based on the detection signal of the electric wave sensor 130, enters the sleep mode, switches from the sleep mode to the operation mode, Brightness, illuminance, luminous intensity, and luminous flux may be automatically controlled.

The light sensor 140 detects whether a human body is present or not in a predetermined region around the illuminator 100 and whether the human body is present or not. (ON) / OFF (OFF) based on the motion detection of the human body, entry into the sleep mode, switching from the sleep mode to the operation mode, and a change in the brightness, illuminance, Or two or more are automatically controlled.

For example, when the presence of a human body or movement of an existing human body is continuously detected through the radio wave sensor 130, the light source unit 140 is kept in an ON state continuously, The light source unit 140 can be switched from the ON state to the OFF state or the sleep mode when the presence of the light source unit 140 or movement of the human body is not detected for more than the predetermined time. The light source unit 140 may be turned on automatically when the presence of a human body or the movement of an existing human body is sensed through the radio wave sensor 130 in the off or sleep mode .

The automatic operation control of the light source unit 140 may be performed by adding the sensing signal of the illuminance sensor 160 to the sensing signal of the electric wave sensor 130.

That is, the lighting apparatus 100 further includes an illuminance sensor 160 for measuring the illuminance of the surroundings.

The light source 140 is turned on / off based on the sensing signal of the electric wave sensor 130 and the sensing signal of the illuminance sensor 160, enters the dormant mode and switches from the dormant mode to the operation mode , Brightness, illuminance, luminous intensity, and luminous flux in the ON state can be automatically controlled.

For example, when the illuminance sensed through the illuminance sensor 160 is less than 10 (㏓), the light source unit 140 automatically enters the operation mode. In this state, the presence or absence of a human body When one or more of the brightness, illuminance, luminous intensity, and luminous flux of the light source unit 140 in the operation mode state is automatically detected when the motion is detected or the presence of the human body detected in the opposite direction or the motion of the existing human body is not detected It can be controlled.

In this embodiment, the lighting device 100 includes a control unit 150. The control unit 150 receives the sensing signal of the electric wave sensor 130 and the sensing signal of the illuminance sensor 160, A mode of controlling ON / OFF, entry into a sleep mode, switching from a sleep mode to an operation mode, brightness, illuminance, luminous intensity, and luminous flux in an ON state However, the present invention is not limited thereto.

The control unit 50 may be configured to control ON / OFF of the radio wave sensor 130 according to the illuminance around the lighting apparatus 100 sensed by the illuminance sensor 160.

For example, when the ambient illuminance of the lighting apparatus 100 is 10 (㏓) or more, the control unit 150 turns off the radio wave sensor 130 to stop the sensing function through the radio wave sensor 130 . This is because it is not necessary to activate the sensing function of the radio wave sensor 130 in a situation where the periphery of the lighting device 100 is bright and the operation of the light source unit 140 is not required. And the lifetime of the radio wave sensor 130 is also intended to be extended.

Although the light source unit 140 includes the PCB 141 and the plurality of LEDs 142 in the present embodiment, the present invention is not limited thereto. Hereinafter, the light source unit 140, 140 will be described in detail.

The PCB 141 is installed inside the case 110. The PCB 141 forms a plurality of light source connecting parts 141a for mounting the light sources in an array form.

The plurality of LEDs 142 are mounted on each of the light source connecting portions 141a of the PCB 141 and substantially emit light.

In this embodiment, the cover 120 is installed on the case 110 so that any one of the cover 120 of different outline, color, and material can be selectively applied according to the installation place or installation purpose of the lighting apparatus 100 It is to be understood that the present invention is not limited thereto.

Referring to FIG. 4, FIG. 4 illustrates a state of use of a lighting device having a light source control function through a radio wave-based sensor according to an exemplary embodiment of the present invention.

As shown in the figure, various types of cover 120 such as hemispherical, quadrangular, and trapezoidal shapes can be selectively applied to the lighting device 100 in addition to the flat curved shape according to the installation place or use thereof, This is because the illumination device 100 is equipped with the electric wave sensor 130 as a sensor for sensing the presence and movement of the human body so that the interference between the sensor and the cover such as a conventional lighting device using an infrared sensor or an ultrasonic sensor So that the sensing function of the sensor is not disturbed.

Next, a lighting apparatus having a light source control function through a radio wave-based sensor according to another embodiment of the present invention will be described with reference to FIG.
