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

In general, in order to reduce power consumption of a lighting device, there is a control method that works with various sensors.

For example, a Pyroelectric Infrared Ray (PIR) sensor, which is mainly used as a conventional room / vacancy sensor, detects a difference between heat and background space emitted from a moving human body and detects whether a person is in a room or vacancy. .

However, such a pyroelectric infrared sensor does not detect whether it is occupied at low speeds or stops, and malfunctions may occur due to interference caused by temperature changes by air conditioning and heating devices such as indoor air conditioners and heaters.

In addition, even if a detectable angle is increased by using a Fresnel optical lens, there is a problem in that a certain wide angle abnormality that cannot be detected is not detected.

An embodiment provides a lighting device and a lighting control method.

Embodiments include a light source, and a control module for outputting a control signal to the light source, wherein the control module includes a camera for photographing objects around the camera to generate image data, a microphone for receiving voice from the surroundings, and generating voice data; And it provides a lighting device including a control unit for generating the control signal by reading the user's lighting control intention from the image data and audio data.

On the other hand, the embodiment of the present invention comprises the steps of receiving image data photographing the surrounding objects, receiving the audio data for the surrounding voice, reading the user's lighting control intention from the image data and the audio data to generate a control signal And emitting light from a light source according to the control signal.

According to the embodiment, in the case of indoor lighting which can adjust the brightness, it is possible to save 20 to 80% of electric energy according to the brightness. In addition, by using the camera-based image analysis function and the user's voice recognition and hand gesture recognition technology to control the brightness of the lighting device automatically or manually to prevent unnecessary waste of power consumption.

In addition, when the user does not exist within the camera recognition range, the brightness level is gradually reduced, and after a certain time has elapsed, power consumption can be prevented by controlling the lighting inadvertently turned on by switching off the power and turning on the standby mode.

In case of automatic brightness adjustment mode, user's inconvenience can be solved by maintaining indoor brightness set by user regardless of environment change through image analysis.

Natural operation is possible by controlling the mode entry through the user's voice recognition and performing detailed control of brightness and on / off through hand gestures.

First, when the operation is started, the microphone 130 and the camera 110 obtains the voice and the image of the surrounding environment and converts the data into data.

The image processor 120 receives image data from the camera 110 (S100), and transforms the image data to generate simplified image data and outputs the simplified image data to the controller 150.

The voice processor 140 periodically receives voice data from the microphone 130 (S200), and when voice data of a predetermined size or more is received from the received voice data, the voice processor 140 determines that the voice data is valid voice data having a command from a user ( S210), the linguistic meaning is extracted from the corresponding speech data and output (S220).

The controller 150 receives an output signal from the voice processor 140 and the image processor 120 to generate a control signal of the lighting module 500.
