1 is a conceptual diagram of a lighting system including a plurality of indoor lights according to the present invention.

A lighting system 1 including a plurality of interior lights according to the present invention includes a front door light module 10 and one or more interior light modules 20 .

The entrance light module 10 is installed in the entrance of an apartment or house and turns on for a certain period of time (the entrance light delay time) when a person's movement is detected, and then turns off. There is a difference in that data can be transmitted to other indoor light modules 20 through the medium of light.

Further, each of the one or more interior light modules 20 includes an illuminance sensor 231 that senses the light emitted from the front door light module 10 and converts it into current, so that a predetermined frequency is generated from an output value of the illuminance sensor 231. After reading the output value of the demodulation module 233 that filters out only the signal and outputs it in the form of a square wave, when the received data is predetermined data or an operation command, the received data through the light emitted through the LED lamp is sent out again.

Therefore, when the front door light module 10 senses a person's movement in the front door and is turned on, at least one of the one or more interior light modules 20 transmits the light emitted from the front door light module 10 through the illuminance sensor 231. After detecting and reading the transmitted signal through the light emitted from the front door light module 10, and then receiving the received data through the light emitted through the LED lamp when the received data is predetermined data or operation command Since the generated data is transmitted to the outside again, the remaining interior light modules 20 also detect the light emitted from the front door light module 10 or other interior light modules 20 through the illuminance sensor 231 and continuously interlock to turn on the light. It becomes.

Hereinafter, the entrance light module 10 and the interior light module 20 will be described in more detail.

2 is a block diagram showing the configuration of an entrance light module, FIG. 3 is a view showing the coupling relationship of some of the components of the entrance light module, and FIG. 4 is a block diagram showing the configuration of an indoor light module, 5 is a diagram illustrating a coupling relationship of some of components of an indoor light module.

The entrance light module 10 includes a human body sensor 11 and a first light transmitter 12.

The human body sensor 11 is a sensor that detects the motion of a person or animal emitting infrared rays, and a pyroelectric IR sensor is used in this embodiment.

The HC-SR501 ultra-wide sensor used in this embodiment outputs a HIGH signal during the delay time when motion is detected. The output voltage of the HIGH signal is 3.3V, and when motion is not detected, the output voltage is 0V LOW state.

When the output value of the human body detection sensor 11 exceeds a predetermined value, the first optical transmission unit 12 transmits a signal obtained by modulating the transmission data into a carrier wave of a predetermined frequency through light emitted through an LED lamp in advance. As a component that functions to emit light for a predetermined time (delay time for front lights), it is configured to include a first light emitting unit 121 and a first driving circuit 125.

The first light emitting unit 121 is driven by the first driving circuit 125 and flickers to transmit a signal obtained by modulating transmission data into a carrier wave of a predetermined frequency to the outside through light. It is configured to include an LED lamp, and is preferably configured to include one or more high-brightness LED lamps.

The first driving circuit 125 is a component that functions to drive the first light emitting unit 121 for a predetermined time (door light delay time) to externally transmit a signal obtained by modulating transmission data into a carrier wave of a predetermined frequency. As an element, it is configured to include a data storage unit 125a and a first modulation module 125b for storing and modulating transmission data.

The data storage unit 125a stores transmission data to be transmitted to the outside when a person's movement is detected at the front door, and the first modulation module 125b converts the transmission data stored in the data storage unit 125a into binary numbers. is modulated into a carrier wave of constant amplitude.

This signal modulation is to transmit information efficiently with less influence of external light or noise, and various frequencies suitable for the communication method used can be used as the frequency of the modulated signal.

For example, when using the same method as the infrared communication method mainly used in remote controls used in home appliances such as TV, audio, and air conditioners, infrared communication is usually modulated into a signal of 37 to 42 kHz, and the first modulation module (125b) can be made to modulate with a frequency of 38 kHz, the most common.

The first driving circuit 125 needs to drive the first light emitting unit 121 so that the signal modulated by the first modulation module 125b is transmitted through the LED lamp, an MCU designed to directly drive a high-brightness LED. (Micro Controller Unit).

Since the LED lamp is a device having a fast response speed, it can be driven to flicker at the frequency (eg, 38 kHz) of the signal modulated by the MCU, and the LED lamp of the first light emitting unit 121 is used for optical communication signal transmission Even if it flickers at the same frequency as the frequency of light, it is continuously recognized by the human eye as a lighted state, so the first light emitting unit 121 driven by the first driving circuit 125 functions as a lighting device and as an optical communication signal transmission device. functions can be performed simultaneously.

When the output value of the human body sensor 11 exceeds a predetermined value, the MCU included in the first driving circuit 125 converts the transmission data stored in the data storage unit 125a into binary and converts the signal to the first modulation module. After being sent to (125b) and modulated into a carrier wave of a predetermined frequency, the first light emitting unit 121 is driven so that the signal is emitted as light for a predetermined time (eg, 30 seconds or 1 minute) through an LED lamp. It may be, and the data storage unit 125a may be configured to be embedded in such an MCU.

Each of the one or more interior light modules 20 includes a second light transmitter 22 and a light receiver 23 .

The light receiving unit 23 reads the output value of the demodulation module 233, which filters out only the signal of a predetermined frequency from the output value of the illuminance sensor 231 and outputs it in the form of a square wave, so that the received data is predetermined operation data or an operation command. As a component that functions to transmit the received data to the second optical transmission unit 22 in case of an emergency, it is configured to include an illuminance sensor 231, a demodulation module 233 and a data recognition unit 234.

The illuminance sensor 231 is a component that measures ambient illuminance, and is preferably configured to include a photodiode or phototransistor.

Both the photodiode and the phototransistor have a characteristic that when there is no light, resistance increases and current does not flow, and when the amount of light increases, resistance decreases and current is generated. A phototransistor has a slower reaction speed than a photodiode, but has an excellent function of converting light into current through amplification.

The demodulation module 233 is a component that filters only signals of a predetermined frequency from the output value of the illuminance sensor 231 and outputs them in the form of a square wave. If light modulated with a frequency of 38 kHz is used for optical communication, BPF ( The received signal is demodulated by designing a Band Pass Filter), filtering out only the signal with a component of 38 kHz, and then outputting it in the form of a square wave.

The data recognition unit 234 reads and interprets (decoding) the output value of the demodulation module 233 to find out the transmission data sent from the transmission side, and then, when the received data is predetermined operation data or an operation command, the received As a component that functions to transmit data to the second optical transmitter 22, it may include an MCU for reading and decoding the output value of the demodulation module 233.

Since various protocols may be used for optical communication, various protocols such as RC5, RC6, SIRC, NEC, and RCA used in infrared communication may be used.

The MCU of the data recognition unit 234 reads and interprets the output value of the demodulation module 233 according to the protocol used to find out the transmission data sent from the transmission side, and then when the received data is predetermined operation data or an operation command Then, the received data is transmitted to the second optical transmitter 22.

According to various embodiments, the light receiving unit 23 may include an OP amplifier 232 . In this case, the OP amplifier 232 functions to amplify the output value of the illuminance sensor 231 and transmits it to the demodulation module 233, thereby improving the reception sensitivity of the optical signal.

The second optical transmitter 22 transmits a signal obtained by modulating the data received from the data recognition unit 234 of the optical receiver 23 into a carrier wave of a predetermined frequency through the light emitted through the LED lamp. As a component, it is configured to include a second light emitting unit 221 and a second driving circuit unit 225.

The second light emitting unit 221 is driven by the second driving circuit unit 225 and blinks to transmit a signal obtained by modulating the data received from the light receiving unit 23 into a carrier wave of a predetermined frequency to the outside through light. As a component for doing, it is configured to include one or more LED lamps, and is preferably configured to include one or more high-brightness LED lamps.

The second driving circuit unit 225 is a component that drives the second light emitting unit 221 to externally transmit a signal obtained by modulating data received from the light receiving unit 23 into a carrier wave of a predetermined frequency, and transmits It is configured to include a second modulation module 225b for modulation of received data.

The second modulation module 225b modulates the signal obtained by converting the data received from the optical receiver 23 into binary numbers into a carrier wave of a constant amplitude.

Various frequencies suitable for the communication method used may be used as the frequency of the modulated signal, but the interior light module 20 transmits not only the optical communication signal transmitted from the front door light module 10 but also the optical communication signal transmitted from other indoor light modules 20. It is preferable that the modulation frequency of the second modulation module 225b is the same as the modulation frequency of the first modulation module 125b of the front door light module 10 (for example, 38 kHz) so that the signal can also be received. .

The second driving circuit unit 225 needs to drive the second light emitting unit 221 so that the signal modulated by the second modulation module 225b is transmitted through the LED lamp, an MCU designed to directly drive a high-brightness LED. (Micro Controller Unit).

As described above, the light receiving unit 23 reads and interprets the output value of the demodulation module 233 to find out the transmission data sent from the transmitting side, and then, when the received data is predetermined operation data or an operation command, receive The converted data is transmitted to the second optical transmission unit 22. When data is transmitted from the optical reception unit 23, the MCU included in the second driving circuit unit 225 generates a signal obtained by converting the received data into binary numbers. After being sent to the second modulation module 225b and modulated into a carrier wave of a predetermined frequency, the second light emitting unit 221 may be driven so that the modulated signal is emitted as light through an LED lamp.

According to one embodiment, the MCU of the second driving circuit unit 225, whenever data is received from the light receiving unit 23, the signal modulated by the second modulation module 225b is radiated as light through the LED lamp. After driving the second light emitting unit 221, the second light emitting unit 221 may be controlled to turn off.

According to this setting, when the data received through the optical receiver 23 is predetermined operation data or an operation command, the second optical transmitter 22 receives the data from the optical receiver 23 and transmits it at a predetermined frequency. After modulating the carrier wave and emitting the modulated signal as light through the LED lamp, when the transmission of the optical communication signal is completed, the interior light module 20 is turned off. Since the modulated signal is emitted as light through the LED lamp only while receiving data from the light receiver 23, the light receiver 23 receives an optical communication signal from the front door light module 10 or other interior light modules 20. The interior light module 20 is turned on only during reception and then turned off.

Therefore, when an optical communication signal is not received from another interior light module 20, when a person's movement is detected in the front door and the door light module 10 is turned on, the interior light modules 20 are interlocked together and turned on, and for a certain period of time (entrance When the front light module 10 is turned off after elapse of the light delay time), the interior light module 20 is also interlocked and turned off.

According to another embodiment, when the MCU of the second driving circuit unit 225 receives data from the light receiving unit 23, the signal modulated by the second modulation module 225b is transmitted for a predetermined time (indoor light delay time; for example, For example, after driving the second light emitting unit 221 to emit light through the LED lamp for 30 seconds, 1 minute, or 2 minutes), the second light emitting unit 221 may be controlled to turn off.

According to this setting, when the data received through the optical receiver 23 is predetermined operation data or an operation command, the second optical transmitter 22 receives the data from the optical receiver 23 and transmits it at a predetermined frequency. After modulating into a carrier wave, the modulated signal is radiated as light through an LED lamp for a predetermined time (interior light delay time), and then the interior light module 20 turns off, so that the front door light module 10 or another interior light module 20 When the optical communication signal is received from ) and the front door light module 10 and other interior light modules 20 are turned off and the reception of the optical communication signal is stopped, the interior light module 20 turns off after a certain time (interior light delay time) has elapsed. It becomes.

Therefore, when an optical communication signal is not received from another interior light module 20, when a person's movement is detected in the front door and the door light module 10 is turned on, the interior light modules 20 are interlocked together and turned on, and for a certain period of time (entrance When the front door light module 10 is turned off after elapse of the light delay time), the interior light module 20 is turned off again after a predetermined time (interior light delay time) has elapsed.
