Referring to FIG. 1 , the light emitting device 1000 may include a control unit 100 , a light emitting diode unit, a sensor unit 400 , and a communication unit 500 . However, the above-described components are not essential for implementing the light emission device 1000 , and thus the light emission device 1000 may have more or fewer components than those listed above.

The light emitting diode unit of the light emitting device 1000 may include a light emitting diode 211 , a first ultraviolet light emitting diode 221 , and a second ultraviolet light emitting diode 231 . In addition, the light emitting diode unit may refer to semiconductor devices that emit light when a current flows in a forward direction.

First, the light emitting diode 211 may be a semiconductor device emitting general light. That is, the light emitting diode 211 may be a semiconductor device that provides an illumination function in the light emitting device 1000 .

In addition, the first ultraviolet light emitting diode 221 and the second ultraviolet light emitting diode 231 may be semiconductor devices emitting ultraviolet light. That is, each of the first ultraviolet light emitting diode 221 and the second ultraviolet light emitting diode 231 may provide a sterilization and disinfection function using ultraviolet light in the light emitting device 1000 .

Specifically, the first ultraviolet light emitting diode 221 may emit first ultraviolet light. Here, the first ultraviolet light may have any one of a wavelength range of 315 to 405 nanometers (nm) or a wavelength range of 280 to 315 nanometers. That is, the first ultraviolet light emitting diode 221 may emit ultraviolet light of UV-A (ultraviolet-A) or UV-B (ultraviolet-B). However, the present invention is not limited thereto.

Here, the second ultraviolet light may have a wavelength range of 100 to 280 nanometers. That is, the second ultraviolet light emitting diode 231 may emit ultraviolet light of UV-C (ultraviolet-C). However, the present invention is not limited thereto.

The sensor unit 400 of the light emitting device 1000 may acquire sensing data on whether a person is present in the sensing area. Here, the sensing region may correspond to a region from which light is emitted in the light emitting device 1000 . However, the present invention is not limited thereto.

For example, the sensor unit 400 may be a lidar sensor. In this case, the sensor unit 400 may acquire sensing data related to whether a person is present by using laser light.

As another example, the sensor unit 400 may be a radar sensor. In this case, the sensor unit 400 may acquire sensing data related to whether a person is present using radio waves.

The type of the sensor unit 400 is not limited to the above-described example, and may include various sensors capable of recognizing whether a person is present in the sensing area or whether a person approaches, such as an infrared sensor.

Meanwhile, the sensing data acquired by the sensor unit 400 may be used by the controller 100 to control the light emitting device 1000 .

The communication unit 500 of the light emitting device 1000 may include one or more modules that enable communication between the light emitting device 1000 and an external terminal. Here, the external terminal may be a user terminal or a sensor device. However, the present invention is not limited thereto.

Also, the communication unit 500 may include one or more modules for connecting the light emitting device 1000 to one or more networks.

The communication unit 500 according to some embodiments of the present disclosure may communicate with an external terminal by wire or wirelessly. Also, the communication unit 500 may receive a control signal for controlling the light emitting apparatus 1000 from an external terminal. In addition, the communication unit 500 may broadcast a beacon signal for detecting the approach of the external terminal. Also, the communication unit 500 may receive a response signal corresponding to the beacon signal from an external terminal. However, the present invention is not limited thereto.

Meanwhile, the controller 100 of the light emitting device 1000 generally controls the overall operation of the light emitting device 1000 . The controller 100 may provide or process a function of the light emitting device 1000 to the user by processing a signal input through the above-described components or driving an application program stored in a storage unit (not shown).

According to some embodiments of the present disclosure, the controller 100 uses the control pattern stored in the storage unit, the light emitting diode 211 , the first ultraviolet light emitting diode 221 , and the second light emitting diode 211 included in the light emitting device 1000 . At least one of the ultraviolet light emitting diodes 231 may be turned on or off.

For example, when the second UV light emitting diode 231 is turned on, the control unit 100 of the light emitting device 1000 may control the second UV light emitting diode ( 231) can be turned off. Here, the second UV light emitted by the second UV light emitting diode 231 may be UV-C (ultraviolet-C) having a wavelength range of 100 to 280 nanometers.

In this case, the controller 100 of the light emitting device 1000 may prevent damage or corrosion of an object exposed to the light due to the second ultraviolet light.

According to some other embodiments of the present disclosure, the control unit 100 uses the sensing data obtained from the sensor unit 400 , the light emitting diode 211 and the first ultraviolet light emitting diode ( 221) and at least one of the second ultraviolet light emitting diode 231 may be turned on or off.

For example, when recognizing that a person is present in the sensing area using the sensing data, the controller 100 may turn on the light emitting diode 211 and turn off the first ultraviolet light emitting diode 221 . In addition, when recognizing that no person is present in the sensing area using the sensing data, the controller 100 may turn off the light emitting diode 211 and turn on the first ultraviolet light emitting diode 221 .

In this case, since the control unit 100 of the light emitting device 1000 turns on the first ultraviolet light emitting diode 221 only when no person is present in the sensing area, the first ultraviolet light that may be harmful to humans is emitted. It can be prevented from being released to humans. Also, the controller 100 may sterilize and disinfect the space in which the light emitting device 1000 is installed by using the first ultraviolet light only when no person is present in the sensing area.

According to another exemplary embodiment of the present disclosure, the control unit 100 uses a control signal received from an external terminal through the communication unit 500 , the light emitting diode 211 included in the light emitting device 1000 , the first At least one of the ultraviolet light emitting diode 221 and the second ultraviolet light emitting diode 231 may be turned on or off.

For example, when the external terminal is a user terminal, the user may transmit a control signal to the light emitting apparatus 1000 using the user terminal. In this case, the controller 100 of the light emitting device 1000 may control the light emitted from the light emitting device 1000 according to the control signal. Accordingly, the user may conveniently control the light emitting apparatus 1000 through the user terminal.

As another example, the controller 100 may control the communication unit 500 to broadcast a beacon signal. In addition, the control unit 100 may receive a response signal corresponding to the beacon signal from an external terminal through the communication unit 500 . Upon receiving the response signal, the controller 100 may turn off the first UV light emitting diode 221 and the second UV light emitting diode 231 and turn on the light emitting diode 211 . Here, the area where the beacon signal is broadcast may correspond to the area where the light is emitted from the light emitting device 1000 . And, the external terminal may be a user terminal.

That is, the controller 100 of the light emitting apparatus 1000 may recognize that the user (user terminal) approaches the area where the beacon signal is broadcast (the area where the light is emitted) through the received response signal. In addition, the controller 100 may turn off the first ultraviolet light emitting diode 221 and the second ultraviolet light emitting diode 231 , and turn on the light emitting diode 211 .

Therefore, since the control unit 100 of the light emitting device 1000 turns on the first UV light emitting diode 221 and the second UV light emitting diode 231 only when a person does not exist in the sensing area, it is harmful to a person. It can prevent ultraviolet light from being emitted to humans. Also, the controller 100 may sterilize and disinfect the space in which the light emitting device 1000 is installed using ultraviolet light only when no person is present in the sensing area.
