Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a circuit diagram of the LED lighting device for sterilization and pest control according to the first embodiment of the present invention.

As shown, the LED lighting device for sterilization and pest control of the present invention,

The converter 10 converts and outputs AC power to DC power, and when connected to the output terminal of the converter 10 to detect a person, the internal switch 21 is turned on to connect the relay unit 30 connected to the rear stage. If the human body sensor 20 and the human body sensor 20 is not detected from the human body sensor 20 to operate the driving power supplied from the converter 10 to the first LED lamp 40 to perform the sterilization function or pest control function. When the human body is detected by the human body sensor 20, the switching is switched so that the first LED 40 is turned off and the relay unit 30 for supplying driving power to the second LED 50 for lighting and the relay It consists of a first LED light 40 and a second LED light 50 for lighting to perform the sterilization function or pest control function that is turned on by the switching operation of the unit (30).

Here, the first LED lamp 40 may be selected from any one of the LED lamp having a sterilizing function or the LED lamp having a pest control function (hereinafter also referred to as 'LED').

The LED lamp having a sterilizing function is a blue LED having a wavelength of 461 nm, and sterilizes food poisoning bacteria.

For reference, UV-LEDs with wavelength scales between 100 and 400 nm are currently used in the field of health care for the disinfection of water and air, wastewater treatment, deodorization, skin disease treatment and medical use.

In particular, the UV-C region is called a germicidal line and has a wavelength of 220-280 nm.

Direct irradiation causes microbial DNA and RNA damage due to photoreactions and shows direct bactericidal effect through inactivation.

In particular, 253.7nm is known to have the most lethal effect on the DNA of microorganisms.

Ultraviolet rays (UV), however, have excellent effects of specific wavelengths in microbial sterilization and phototherapy, but they cause DNA damage and immunosuppression of the retina, cornea and skin cells of the eye by the selection and irradiation time of various wavelengths. .

Therefore, LED having a sterilization function according to the present invention uses a blue LED of 461nm wavelength band which is harmless to human body and has excellent sterilization effect.

In addition, the LED having a pest control function according to the present invention uses a yellow LED having a wavelength range of 580 ~ 620nm.

The operation of the LED lighting device for sterilization and pest control according to the first embodiment of the present invention configured as described above will be described.

First, when a power source AC is applied, the applied AC power source AC is converted into a DC voltage through the converter 10 and passes through the first sensor 40 and the second LED through the human body sensor 20 and the relay unit 30. 50 will be supplied.

At this time, if the internal switch 21 is turned off because no human is detected through the human body sensor 20, the relay unit 30 does not operate and the driving voltage provided through the converter 10 is relay unit 30. It is provided only to the first LED (40) through the fixed contact (S1) → switch piece (RS) → movable contact (S2) of the first LED light 40 is lit and performs a sterilization or pest control function.

In this state, when a person is detected through the human body sensor 20, the internal switch 21 is turned on.

Therefore, power is supplied to the coil unit RC of the relay unit 30, and the switch piece RS of the relay unit 30 is switched to the movable contact S3.

Therefore, the driving voltage provided through the converter 10 is provided only to the second LED 50 through the fixed contact S1-> switch piece RS-> movable contact S3 of the relay unit 30, so that the second LED lamp ( 50) is turned on to perform the normal light function.

Figure 2 is a circuit diagram of the LED lighting device for sterilization and pest control according to a second embodiment of the present invention, Figure 3 is a detailed block diagram of the sensor unit and the blocking unit of FIG.

As shown, according to the second embodiment of the present invention, the blocking unit 60 and the sensor unit 70 are further included.

The blocking unit 60 cuts off the power supplied to the first LED lamp 40 that performs a sterilization function or a pest control function when a noise signal or an opening / closing detection signal is received from the sensor unit 70.

The blocking unit 60 is a receiving unit 61 for wirelessly receiving a noise signal or an opening / closing detection signal transmitted from the sensor unit 70 and a relay driving unit when a noise signal or an opening / closing detection signal is input from the receiving unit 61. The relay 62 driving the control unit 62 for driving a predetermined time and a cutoff switch SW for cutting off the power supplied to the first LED 40 by the output of the control unit 62. 63).

The sensor unit 70 is installed in the vicinity of the door of the place where the lighting device of the present invention is installed, the noise sensor 71 for detecting the noise in the vicinity of the door, the opening and closing detection sensor 72 for detecting the opening or closing of the door and When the noise signal input through the noise sensor 71 or the door opening / closing signal input through the opening / closing detection sensor 72 is input, the transmission control unit 73 wirelessly transmits it to the blocking unit 60.

Here, the noise sensor 71 of the sensor unit 70 detects noise near the entrance door, which detects footsteps when a person approaches the door, and before the first LED light 40 is opened. It is a sensor to be blocked.

In addition, the opening and closing detection sensor 72 is a sensor for detecting the state that the door is opened so that the first LED 40 is already blocked before a person enters the room.

For this reason, after a person enters the place, a detection signal is generated by the human body sensor 20, whereby the first LED 40 is turned off, where the first LED 40 is turned off. This is to provide a reassuring function to the user having a kind of anxiety even though there is no harm because of a slight time difference.

Therefore, even if a person is not detected in the room indoors, when the door of the place is opened or a popular chuck is detected near the door, the first LED lamp 40, which is an LED lamp having a sterilization function or an LED for pest control, is fixed. By turning off the time, when the user enters the room, whether the human body is detected or not, the first LED 40 is already kept off.

As described above, the present invention is illuminated by an LED for lighting when there is a person in a place such as a food warehouse, a restaurant cooking room, a kitchen, a bathroom, and when there is no person, by an LED having a sterilizing function or an LED for pest control. It does not use LED for sterilization or pest control separately, it provides cost saving effect.

In addition, the present invention promotes safety by using harmless LEDs that are harmless to humans as LEDs for sterilization or pest control.
