Anti-virus sensor lighting module

The present invention relates to an anti-virus sensor light, and more specifically, to an anti-virus sensor light module that combines a UVC 275nm LED with a light that detects movement and outputs light to transform the light into a device that sterilizes the lighting space.

Recently, with the rapid development of means of transportation, freedom of movement has become more active, exchanges between countries have become more active, and foreign travel culture is rapidly increasing, which is becoming a major cause of the spread of infectious diseases. In other words, cases of global pandemic outbreaks such as MERS, new flu, SARS, COVID-19, etc., in which an infectious virus in a specific region contaminates other regions, occur frequently.

As global awareness of this global pandemic increases, new virus sterilization services that make virus sterilization routine are in demand. In particular, a service is needed to prevent the spread of the virus by regularly sterilizing spaces where everyday items are placed, such as shoe racks and clothes hangers, or entrances to buildings or residences where people frequently come and go.

In general, ultraviolet rays (UV) are used as a means of sterilizing everyday items. In particular, UV-C sterilizing power in the 100~280nm wavelength range is so excellent that it has the advantage of being able to sterilize 99.99% of viruses even in a short period of time. However, ultraviolet sterilization has become a problem because it can be harmful to the human body, causing skin damage and aging.

In addition, a modular sterilizer has not yet been developed. Conventionally, in order to install a sterilizer in a space such as a doorway or shoe cabinet, separate wiring had to be installed and connected to a power source. Additionally, there were problems such as having to secure the sterilizer with nails or adhesives.

The present invention will be reviewed below with reference to the drawings. In describing the present invention, if it is determined that a detailed description of related known technology or configuration may unnecessarily obscure the gist of the present invention, the detailed description will be omitted. will be.

In addition, the terms described below are terms defined in consideration of the functions in the present invention, and may vary depending on the intention or custom of the user or operator, so the definitions should be made based on the content throughout the specification explaining the present invention.

Hereinafter, an embodiment of the present invention will be described in detail based on the attached drawings FIGS. 1 to 9.

The present invention relates to an anti-virus sensor light module, and as shown in Figures 1 and 2, it largely consists of a UVC 275nm LED (231), an LED PCB (230), a donut-shaped case (210), a lighting tube (220), and a PIR. It consists of a sensor 110 and a controller 300.

As shown in FIG. 1, the LED PCB 230 of the present invention has the morphological characteristic of being formed as an arc-shaped substrate with a portion of a donut-shaped substrate cut, and has a structure in which UVC 275nm LEDs 231 are protruded at equal intervals. It has characteristics.

The donut-shaped case 210 of the present invention is a case in which a donut-shaped shape is adopted to house the LED PCB 230, and through holes through which the UVC 275 nm LED 231 penetrates are formed at equal intervals in the downward direction.

Ultraviolet sterilizing LEDs, which are generally used in people's residential environments, have a frequency band close to the visible light region and are characterized by a very short sterilization distance.

This is not only the reason why it was selected as a device for human safety, but also because as the frequency band moves away from visible light, ultraviolet rays cannot pass through general transparent casing materials.

In other words, in the case of ultraviolet sterilizing LEDs using transparent casing materials such as general acrylic or glass, the effective sterilizing distance is very short, so there is a problem in that they cannot perform an effective function at the apartment entrance entrance, laboratory entrance, or elevator indoor sterilization.

The ultraviolet rays emitted by the UVC 275nm LED 231 used in the present invention are in an ultraviolet frequency band far from visible light, and have a very long sterilization effective distance, so they are mainly used for industrial and medical purposes and have an effective function in sterilizing apartment entrances, laboratory entrances, or indoor elevators. Although it has excellent sterilization ability, it is harmful to the human body, so it has limitations and must be handled very carefully.

Meanwhile, as shown in FIG. 9, the UVC 275nm LED (231) does not pass through general transparent casing materials due to the frequency characteristics of ultraviolet rays, but has the characteristic of passing through topaz or quartz, so each individual LED is made of quartz, which is cheaper than topaz, in advance. It is cased.

Therefore, it can be seen that in order to effectively use the UVC 275nm LED 231, the UVC 275nm LED 231 should not be housed with another transparent casing material.

In order to effectively use the UVC 275nm LED 231, the present invention forms holes at equal intervals in the donut-shaped case 210, and exposes the UVC 275nm LED 231 to the outside through the holes to operate the sterilization function. I'm doing it.

The lighting fastening tube 220 of the present invention is a lighting coupling part formed on the inner circumference of the donut-shaped case 210, and a lighting coupling plate ( 221) is formed.

The lamp 100 coupled to the lamp fastening tube 220 is a general optical lamp, and according to the present invention, it operates as a sensor lamp that outputs light when the PIR sensor 110 detects movement and generates a motion detection signal.

The present invention provides a device that operates a general optical lighting lamp using a sensor, etc. However, it goes without saying that even if a commercially available sensor lamp is attached to the lighting tube 220, it operates normally as a sensor lamp.

The lighting area (A) where the present invention is installed may be an entrance to a building or residence as shown in FIG. 3, or an interior space of a shoe cabinet as shown in FIG. 4, and the lighting 100 includes a light output unit 130 and a glass cover 150. ) may include.

In addition, as shown in FIG. 6, it is desirable to provide a connector 320 for connection with a controller 300 to be described later so that power to the lighting can be applied by fastening the lighting tube 220.

The PIR sensor 110 of the present invention is formed on the lower side of the lighting tube 220 or the donut-shaped case 210.

When the PIR sensor 110 is formed in the center of the lighting tube 220, the lighting lamp 100 fastened to the lighting tube 220 forms a hole exposing the PIR sensor 110 at the coupling portion. It is desirable to do so.

However, in this case, the lighting 100 may need to be repaired or a dedicated light may need to be used, so additional holes are formed at equal intervals from the holes formed in the lower part of the donut-shaped case, and the PIR sensor ( 110) is preferably combined.

In this case, as shown in FIG. 1, due to the shape characteristics of the LED PCB 230, the PIR sensor 110 will be placed below the controller.

The PIR sensor 110 is a device that detects movement by people or animals in the lighting area (A). In the present invention, in order to improve the motion detection ability, the PIR sensor 110 is equipped with a Fresnel lens 111 as shown in FIG. 7. ) can be combined.

The Fresnel lens 111 shown in FIG. 7 collects infrared rays from a large aperture and focuses them on the PIR sensor 110, thereby improving the detection sensitivity of infrared rays emitted from a person or animal within the lighting area A.

The PIR sensor 110 senses the amount of change in the input infrared rays and transmits it to the controller, and the controller generates a motion detection signal when the amount of change in the sensed infrared rays is greater than the preset motion judgment reference amount.

This process of generating a motion detection signal can be controlled by the controller 300, which can set the sensitivity of the PIR sensor 110 to the amount of infrared change.

The reason for using the PIR sensor 110 and the Fresnel lens 111 as the motion detection sensor in the present invention is to ensure the safety of the UVC 275nm LED 231 used in the present invention against human risk, as described above.

In other words, the present invention ensures the safety of operation of the UVC 275nm LED 231 by maximally detecting the absence of people or animals inside the lighting area A.

The controller 300 of the present invention is preferably formed in an arc shape so that it can be inserted into the remaining insertion space of the LED PCB 230 in the donut-shaped case 210, but is not necessarily limited to this.

As shown in FIG. 6, the controller 300 is connected to the power terminal of the LED PCB 230, the power terminal of the light 100, the PIR sensor 110, and an external power source, and detects information of the PIR sensor 110. Accordingly, the operation of the UVC 275nm LED 231 and the lighting lamp 100 is controlled.

In detail, the controller 300 controls the lighting 100 and the UVC 275nm LED 200. When a motion detection signal is input from the lighting 100, the UVC 275nm LED 200 is controlled according to the sterilization operation control algorithm 310. controls.

At this time, the controller 300 controls the UVC 275nm LED 200 according to the set sterilization operation control algorithm 310, so that the UVC 275nm LED 200 is turned ON only when there are no people or animals inside the lighting area (A). Control.

Specifically, the sterilization operation control algorithm 310 includes a light on operation control unit 311, a UVC 275 nm LED on operation standby unit 313, a UVC 275 nm LED on operation control unit 315, and a UVC 275 nm LED off operation, as shown in Figure 8. It may include an operation maintenance unit 317.

The lighting on operation control unit 311 can control the lighting 100 to be turned on for a set lighting time (T1) from the generation time of the motion detection signal transmitted from the lighting 100.

In addition, the UVC 275nm LED on-operation standby unit 313 can wait for the UVC 275nm LED 200 to turn on after a set waiting time (T2) from the time the lighting 100 is turned off.

Accordingly, movement within the lighting area A is detected and sterilization is performed a certain period of time from the time the lighting 100 is turned on, thereby contributing to greater safety.

The UVC 275nm LED on operation control unit 315 maintains the ON operation of the UVC 275nm LED 200 for a set sterilization time (T3), and can control the UVC 275nm LED 200 to be turned off when a motion detection signal is generated. .

Accordingly, while the UVC 275nm LED 200 is turned on and sterilization is in progress, if movement is detected in the lighting area A and the lighting 100 is turned on, sterilization can be stopped immediately.

The UVC 275nm LED off operation maintenance unit 317 can maintain the off operation of the UVC 275nm LED 200 when the lighting lamp 100 is turned on.

Accordingly, if the lighting 100 is turned on when the ON operation of the UVC 275nm LED 200 begins, the UVC 275nm LED 200 may not be turned ON but maintain the OFF operation.

By configuring this sterilization operation control algorithm 310, the UVC 275nm LED 200 is controlled to turn on only when there are no people or animals inside the lighting area A, thereby preventing damage to the human body due to ultraviolet irradiation. .

Accordingly, the sterilization operation control algorithm 310 is performed according to the steps shown in FIG. 8.

First, check whether a motion detection signal is generated from the PIR sensor 110. If a motion detection signal is generated, the UVC 275nm LED 200 is turned off, and then the lighting 100 is controlled to be turned on for the set lighting time (T1).

On the other hand, if the motion detection signal is not generated, it is checked whether the set waiting time (T2) has been exceeded from the time the lighting 100 is turned off. If the set waiting time (T2) is exceeded, the lighting 100 is turned OFF, and then the UVC 275nm LED 200 is controlled to be turned ON for the set sterilization time (T3).

The sterilization operation control algorithm 310 as described above may be implemented differently depending on the nature, structure, shape, etc. of the lighting area A of the anti-virus sensor according to the present invention. That is, the sterilization operation control algorithm 310 can be configured by considering the inflow and outflow patterns of people or goods in the lighting area A.

According to the anti-virus sensor light according to the present invention, a UVC 275nm LED (200) with a virus sterilizing function can be organically combined with a lighting lamp (100) commonly used in daily life.

Therefore, according to the present invention, there is an advantage that the general lighting 100 can be used by expanding the function of an anti-virus sterilizing light and a sensor light by simply replacing the existing lighting lamp or attaching some additional components.

In addition, when a sensor light with a built-in motion detection sensor is used as the lighting 100, movement in the lighting area (A) is detected using the motion detection sensor built into the sensor light, and the controller uses this to sterilize the light. By providing a sterilization operation control algorithm that determines whether or not to sterilize, there is an effect of making operation simpler.

Therefore, the anti-virus sensor light module according to the present invention enables periodic sterilization without causing damage to the human body, while minimizing the manufacturing cost. At the same time, the function of a general lighting light can be expanded into a sterilizing light and a sensor by simple combination. User accessibility to the invention can be improved.

The drawings shown above for explanation of the present invention are one embodiment of the present invention, and as shown in the drawings, it can be seen that various types of combinations are possible to realize the gist of the present invention.

Therefore, the present invention is not limited to the above-described embodiments, and as claimed in the following claims, anyone skilled in the art can make various changes without departing from the gist of the invention.
