FIELD OF THE INVENTION [0001] The present invention relates to a lighting device,

The present invention relates to a lighting apparatus and a lighting control method.

Generally, there is a control method which is interlocked with various sensors in order to reduce power consumption of a lighting apparatus.

For example, in the case of a pyroelectric infrared ray (PIR) detection sensor, which is mainly used as a conventional room / vacant room sensor, a difference between a heat radiating from a moving human body and a background space is detected to detect a room or vacancy of a person .

However, in the case of such a super-type infrared sensor, malfunction may occur due to interference due to a temperature change caused by an air conditioner or an air conditioner such as an indoor air conditioner or a heater without detecting the re-

In addition, even if the Fresnel optical lens is used to increase the detectable angle, there is a problem in that it is not possible to detect a certain wide angle of view capable of securing a line of sight.

Embodiments provide a lighting apparatus and a lighting control method.

The control module includes a camera for capturing a surrounding object and generating image data, a microphone for receiving the surrounding sound to generate the sound data, and a control module for outputting control signals to the light source. And a controller for reading the user's illumination control intention from the image data and voice data to generate the control signal.

On the other hand, the embodiment includes a step of receiving image data of an image of a surrounding object, a step of receiving voice data of a surrounding voice, a step of reading a user's illumination control intention from the image data and voice data, And emitting light from the light source in accordance with the control signal.

According to the embodiment, it is possible to save 20 ~ 80% of electric energy according to the brightness in the case of the indoor lighting capable of adjusting the brightness. In addition, unnecessary waste of power consumption can be prevented by automatically or manually controlling brightness of a lighting device by using a camera-based image analysis function and a user's voice recognition and hand movement recognition technology.

In addition, if there is no user in the camera recognition range, the brightness level is gradually decreased. After a certain time has elapsed, power consumption can be prevented by controlling lighting by the user inadvertently through power-off and standby mode switching.

In the brightness automatic adjustment mode, user's discomfort can be solved by maintaining the user's set brightness regardless of environmental change through image analysis.

It is possible to perform natural operation by controlling the entry of the mode through voice recognition of the user and performing detailed brightness control and on / off control through the hand operation.

That is, the image processing unit 120 may divide one image frame into a plurality of units, detect edges by each unit, and extract features to generate simplified image data according to the characteristics.

Such an image processing method can be implemented by applying various known image feature detection methods.

The microphone 130 receives voice from an object located in front of the lighting device 21 and outputs voice data to the voice processing unit 140.

When a voice of a predetermined size or larger is detected from the received voice data, the voice processing unit 140 determines the voice data as valid voice data and identifies contents having a linguistic meaning from valid voice data.

The control unit 150 receives the output signals from the image processing unit 120 and the voice processing unit 140 and generates and outputs control signals of the illumination module 500 according to the mode.

The control module 22 may be set to an automatic mode, a manual mode, or a power on / off mode according to a user's selection.

In the automatic mode, the control unit 150 receives the output from the image processing unit 120 and the original image data, and generates a control signal for controlling the brightness of the illumination so as to maintain a constant brightness irrespective of changes in the surrounding environment.

That is, when the brightness of the surrounding environment is set to 100, the brightness of the current image data is analyzed to enhance the light output of the lighting module 500 such that the brightness is 100 when the brightness of the current image data is 90 Signal.

In the manual mode, the controller 150 receives an output signal from the image processor 120, recognizes the hand gesture from the image data, and generates a control signal for controlling the brightness according to the gesture.

Hereinafter, the operation of the control module 22 of the present invention will be described with reference to FIG.

First, when the operation is started, the microphone 130 and the camera 110 acquire voice and images of the surrounding environment, respectively, and convert them into data.

The image processing unit 120 receives the image data from the camera 110 (S100), converts the image data into a characterized image data, and outputs the simplified image data to the controller 150.

The voice processor 140 periodically receives voice data from the microphone 130 in step S200. When voice data of a predetermined size or larger is received, the voice processor 140 determines that the voice data is valid voice data having a command from the user S210), extracts the linguistic meaning from the voice data, and outputs it (S220).

The control unit 150 receives an output signal from the audio processing unit 140 and the image processing unit 120 and generates a control signal of the illumination module 500. [

In detail, when the simplified image data is received as an output signal from the image processing unit 120, the controller 150 determines whether a user is detected from the simplified image data at step S120.

The determination of presence or absence of a user may store a feature for a user, match the feature with a simplified image data, and determine that a user exists if similarity within an error range is found.

If it is determined that the user exists, the controller 150 selects a mode according to an output signal from the voice processing unit 140. [

That is, if the voice data is one of the mode data, the control unit 150 sets the corresponding mode according to the output signal of the voice processing unit 140 (S130).

When the output signal instructing the automatic mode is received from the audio processing unit 140, the controller 150 analyzes the brightness of the current image data according to the set reference brightness, And generates a control signal (S180).

If an output signal instructing the manual mode is received from the audio processing unit 140, the hand operation is recognized from the simplified video data at step S140.

The hand gesture recognition stores the data on the hand gesture, and if the similarity in the error range is found by matching the simplified image data and the data on the gesture motion, it can be judged that the corresponding gesture has proceeded.

At this time, the stored hand gesture data can separately store the hand gesture for the brightness of the illumination and the gesture for the illumination on / off, and when the stored specific gesture is recognized, the control unit 150 controls the brightness control (S150).

The control unit 150 outputs a lighting control signal for controlling the lighting module 500 to the driving unit of the lighting module 500 according to the brightness control signal (S160).

On the other hand, when an output signal instructing the power on / off mode is received from the voice processor 140, the controller 150 generates a power control signal according to whether the output signal is on or off (S260) And outputs the lighting control signal accordingly.

On the other hand, if no user is detected from the simplified image data, control is performed such that the brightness of the illumination gradually decreases when a predetermined time has elapsed (S250), and if the user is not detected during a predetermined period of time, And generates and outputs a power control signal (S260).

The illumination module 500 receives the illumination control signal and emits light in accordance with the illumination control signal.
