Description

Disinfection lighting system

Technical field

The invention relates to a disinfection device.

Background technique

Light has the effect of disinfection. By irradiation with light of a specific wavelength, such as ultraviolet light (UV), effects such as inactivation of bacteria, fungi, or viruses can be achieved. Once the mercury lamp was the only option for disinfection and sterilization. Ultraviolet (UV) light has been used in industry and health and sanitation for many years. The new generation of LEDs is challenging traditional UV fluorescent light sources. With the advancement of UV LED technology, LED ultraviolet light equipment is more compact, more powerful, non-toxic, long-lived, energy-saving, allowing nearly unlimited on / off switching.

It is well known that ultraviolet radiation emitted at certain wavelengths is mutagenic to microorganisms. Subtype C of the UV spectrum (UVC), also known as "sterilizing" UV radiation, is generally considered to be in the range of 100-280 nanometers. In one application, UV radiation emitted at about 253.7 nanometers can be used to "inactivate" (ie, destroy, render harmless, or inhibit its growth, reproduction) certain microorganisms. The "dose" of UVC radiation required to inactivate a particular microorganism is often referred to as the product of UVC radiation intensity and radiation time. Dose is usually measured in microwatt seconds per square centimeter. Different doses are needed to inactivate different microorganisms.

In places where microorganisms may be widespread, including hospitals, laboratories, gyms, locker rooms, bathrooms, washrooms, kitchens, and many other places, preventing the erosion of certain microorganisms is often an important issue. For example, in a hospital operating room, it may be important to inactivate microorganisms on the surgical site and on many surfaces of the operating room, such as the operating table. This is usually achieved by using special UV lamps fixedly mounted on the operating room ceiling.

However, for spaces where people often move, including the operating room, fixed disinfection equipment can only sterilize specific objects or areas, and other areas where bacteria spread cannot be automatically sterilized; therefore, a disinfection system is needed that can The interior space is sterilized without the need for additional special installation arrangements. It can identify different materials and provide light projection based on the characteristics of different materials, and the device can recognize the presence of people.

In addition, the light projection unit 110 further includes a rotation motor capable of rotating the light projection head 111, the light deflector 112, and the disinfection light source 113 in any desired direction based on an input of the control unit 130. Of course, other rotating mechanisms can also be used, such as a cam mechanism, a gear mechanism, or any other suitable rotating mechanism.

The light deflector 112 uses a galvanometer, and may be any other device capable of controlling the direction of light projection.

The control unit 130 is electronically coupled to the light projection unit 110, the memory unit 140, the camera unit 120, and the remote unit 160. The control unit 130 may control the camera unit and the light projection unit 110 according to a user input or automatically.

The camera unit 120 includes a camera 121 and a plurality of sensors 122. The camera unit 120 is configured to scan at least one indoor object and store the scanned object information in the memory unit 140. In addition, the plurality of sensors 122 are adapted to sense the motion of the scanned item and other predefined parameters. An IP (Internet Protocol) camera rotated at a 360-degree angle can be used in order to enlarge the scanning area and remote control.

As shown in FIG. 2 and FIG. 3, the disinfection unit 200 has a housing 230, and the light projection unit 110 and the camera unit 120 are installed in the housing 230. The housing 230 has a front end 220 and a rear end 210. The front end 220 of the case 230 is covered by a transparent glass cover 250. The housing 230 is connected to the power interface 260 at the rear end 210. Both the disinfection unit 200 and the lighting unit 170 are in electrical communication with the power supply unit 150 through a power supply interface.

The light projection unit 110 and the camera unit 120 are surrounded by a plurality of illumination bulbs 240 at a front end 220 of the housing 230. The housing 230 also houses a control unit 130 and a memory unit 140.

The light projection unit 110, the camera unit 120, the memory unit 140, the control unit 130, and a lighting bulb 240 having an appropriate shape and size accommodated in the bulb housing 230. After the power interface 260 is connected to the power unit 150, the power unit 150 Get electricity.

After the user turns on the power 150 and the camera unit 120 starts scanning the closed area to be disinfected or disinfected, the camera unit is transmitted to the control unit 130, and the control unit automatically recognizes at least one object to be disinfected based on the predefined parameters. The control unit 130 then allows the light projection unit 110 to project at least one light beam 114 on the selected object (as shown in FIG. 4).

A user may manually perform a disinfection operation on the disinfection unit 200. The user may also establish a connection between the remote operation unit 160 and the disinfection unit 200, and then enter an instruction on the remote operation unit 160. The remote operation unit 160 may be a mobile phone, a touch screen display, a computer, a notebook computer, or a remote control, etc., which can aim and control the lighting direction, intensity, time, etc. of the disinfection unit 200.

The control unit 130 has an artificial intelligence and machine learning module, a positioning module, and an object detection module, and is used for the automatic function of the disinfection unit 200. The control unit 130 uses these modules to automatically select, identify, and sort various objects to be disinfected, and automatically provides light processing such as ultraviolet rays according to predetermined parameters of the objects.

The positioning module provides a complete visualization module to locate objects using the camera unit. The positioning module needs a preprocessing algorithm to segment the scene into objects. Ideally, the pre-processing algorithm should be able to segment unstructured scenes into objects in real time using visual cues (such as shapes, textures, edges, and colors).

Artificial intelligence and machine learning modules use machine artificial intelligence and learning algorithms to estimate predictive models that are best generalized to specific types of data. Therefore, in order to implement machine learning and artificial intelligence to solve problems, there must be a large number of examples that can be used by learning algorithms to understand the behavior of the system, and machine systems can generate similar types of predictions. Learning algorithms provide new data examples. The system can record and learn the various treatment methods used by the user for different physical conditions. E.g. If the user disinfects a specific item with ultraviolet light of a specific intensity and shape, this system uses artificial intelligence and machine learning modules to learn and record all events that occur during the disinfection, and in the future, if similar items appear, use it from previous similar programs In the middle school, the disinfection program can be provided automatically according to the learning situation.

Referring to FIG. 4, an application scenario of the lighting disinfection system is used in a bathroom. The disinfection unit 200 is installed on the ceiling 410 of the bathroom 400 together with the lighting unit. Here, the disinfection unit 200 is installed in a conventional lamp holder 430 and projects the UV light beam 114 onto the bathtub 420.

The disinfection lighting unit responds to a variety of situations:

In case 1, a normal household light is illuminated, and at this time, a person, a pet, or any other organism is present in the room.

In the second case, no light is irradiated. This happens when the user has just left the room and the lighting device stops lighting white light.

Case three, the room is being scanned and an object or article requiring disinfection or disinfection is identified based on its frequency of use and predetermined parameters. No one was in the room at this time.

Case four, the system projects UV light onto the identified object or object, and the room is unoccupied at this time.
