- at least one second UV-C lamp (4) distributed in the room (2) to be illuminated and disinfected,
- at least one proximity sensor (5) distributed in the space (2) to be illuminated and disinfected, and
- An activation control device (6) which is connected to the lamps (3, 4) and the proximity sensors (5).

Description

OBJECT OF THE INVENTION

The invention relates to a device for lighting and disinfecting spaces such as bathrooms, elevators, offices and others.

BACKGROUND OF THE INVENTION

The use of UV-C light as a germicidal agent is well known. It is now being installed in hospital operating rooms or, in China, above intensive care unit beds for COVID-infected patients.

However, simultaneous use with human occupation is not possible, since exposure to this light is also harmful to humans. For this reason they cannot safely be used as disinfectants, which is solved with the device according to the invention.

DESCRIPTION OF THE INVENTION

• - wenigstens eine erste Leuchte mit sichtbarem Lichtspektrum, die in dem zu beleuchtenden und zu desinfizierenden Raum verteilt ist,
• - wenigstens eine zweite UV-C-Leuchte, die in dem zu beleuchtenden und zu desinfizierenden Raum verteilt ist,
• - wenigstens einen Näherungssensor, der in dem zu beleuchtenden und zu desinfizierenden Raum verteilt ist, und
• - ein Anschaltsteuergerät, das mit den Leuchten und Näherungssensoren verbunden ist.

The device for lighting and disinfecting rooms according to the invention comprises, in its most basic embodiment:

• - at least a first lamp with visible light spectrum distributed in the space to be illuminated and disinfected,
• - at least one second UV-C lamp distributed in the room to be illuminated and disinfected,
• - at least one proximity sensor distributed in the space to be illuminated and disinfected, and
• - A power-on controller connected to the lights and proximity sensors.

With this configuration it is possible to control the operation so that when the control unit receives the presence signals from the motion detectors installed at different points of the area to be monitored, in the bathrooms, elevators and offices, etc., it activates the first lighting lights and the second UV-C lights are deactivated so that light is available for the users, and when the motion detectors no longer detect people, preferably after a time delay, the first lighting lights are switched off and the second UV-C lights are automatically activated, which disinfects the pathogens reached by the luminaires, without harming people, which was the desired benefit, with the additional benefit of not having to duplicate or oversize the electrical installation (cable sections, electrical protection devices), since there is no is possible, the two lamp types gl switch on at the right time.

Multiple movement sensors are preferably used, since if one movement sensor fails, the other sensors recognize the signal and send it to the control unit. To ensure a good functioning of the system, it is also preferable that the components are duplicated (double relays, double controller) to avoid technical failures and accidental exposure of people to UV-C light (damages eyes and skin). .

DESCRIPTION OF A PRACTICAL EMBODIMENT OF THE INVENTION

• - wenigstens eine erste Leuchte 3 mit sichtbarem Lichtspektrum, die in dem zu beleuchtenden und zu desinfizierenden Raum 2 verteilt ist,
• - wenigstens eine zweite UV-C-Leuchte 4, die in dem zu beleuchtenden und zu desinfizierenden Raum 2 verteilt ist,
• - wenigstens einen Näherungssensor 5, der in dem zu beleuchtenden und zu desinfizierenden Raum 2 verteilt ist, und
• - ein Anschaltsteuergerät 6, das mit den Leuchten 3, 4 und den Näherungssensoren 5 verbunden ist.

The device 1 according to the invention for lighting and disinfecting rooms 2 comprises:

• - at least a first lamp 3 with visible light spectrum, distributed in the space 2 to be illuminated and disinfected,
• - at least one second UV-C lamp 4 distributed in the room 2 to be illuminated and disinfected,
• - at least one proximity sensor 5 distributed in the space 2 to be illuminated and disinfected, and
• - An Anschaltsteuergerät 6, which is connected to the lights 3, 4 and the proximity sensors 5.

The control unit 6 preferably includes a timer 60. In this way, the second lights can be switched on at a configurable time, e.g. B. 30 seconds, after the motion detectors detect no more movement, in order to additionally ensure that no people are present at the time of switching on. In the event that movement is detected after the countdown has started, the countdown will start again with the set total time until no more movement is detected by the proximity sensors.

In order to increase security, at least two movement sensors are preferably connected to the control unit 6 in order to ensure redundant detection. If one of the sensors fails, the other will continue to detect presence and prevent the second lights 4 from turning on (and the first lights 3 off).

Finally, it should be pointed out that the device 1 can consist of lamps in which at least a first lamp 3 and a second lamp 4 are integrated. Thus, both types of light - white and UV-C light - can be present in the same fixture (the electronic circuit would be the same), especially in new installations and in tight spaces such as elevators or toilet cubicles.

Having sufficiently described the subject of the invention, as well as its preferred practical embodiment, it should be noted that the embodiments given above and illustrated in the accompanying drawings can be varied in detail as long as they do not change the basic principle.
