Description

The utility model relates to multi-function devices, namely closed LED lights with bactericidal air disinfection function. The light can be designed for installation in Armstrong ceilings and surface mounting, and can also be used in places where people are constantly present (e.g. offices, Schools, hospitals, production facilities, etc.).

The utility model is from the prior art RU 122820U1 from December 10th, 2012, N05K5 / 00, in which an LED ceiling light is described, comprising a flat body with rear and side walls and a translucent window and LEDs on plates which are distributed on the surface of the rear wall of the body and fastened thereon . The side walls are in the form of prefabricated elements with four profiles of the same shape and rectangular cross-section.

The structure of the aforementioned luminaire gives the device a good appearance and enables convenient installation, although the additional application as an air disinfection device is not guaranteed.

An air ionizer according to the utility model is also from the prior art RU44514 U1 of March 27, 2005, A61N1 / 44 known, comprising a body and an emitter. The seat of the ionizer body corresponds to the shape and size of the installation slot of a computer drive with appropriate fasteners. This utility model relates to a device for ionizing air and can be used in the home, in medicine, in pharmacology, in agriculture (cattle, poultry, plants and fish farming) and in various branches of industry.

A disadvantage of the known device is its limited use.

Measured by the intended use and the technical problem to be solved, the state of the art closest to the present utility model is the lighting device with anion generator KR20180131292 A dated 10.12.2018 A61L9 / 013, which has disinfection and deodorization functions. This lamp is equipped with an anion generator with antibacterial and deodorization functions. The lighting fixture of the device installed on a ceiling or a wall surface and operated with an external energy source comprises: a lamp; a bracket for the lamp that is in close contact with the ceiling or wall surface; a ball which is connected to protect the inside of the mounting part of the lamp and has an opening in the middle; an anion generator that protrudes through the opening formed in the center of the ball and generates anions for adsorption and removal of dust; a socket on which the anion generator is mounted; a power amplifier for external power supply to supply the anion generator with high voltage; a temperature sensor module mounted at the end of the anion generator for measuring the room temperature and for transferring the measured room temperature to the room temperature controller; and a module for mounting an antibacterial deodorant, which is attached to the temperature sensor module via a screw connection for exchange and mounting and contains a natural extract with antimicrobial and deodorising functions and distributes it through its side opening. According to the configuration described above, the temperature sensor module is firmly connected to the end of the anion generator protruding from the ball, which makes it possible to measure the temperature in the room and to regulate it according to the measurement results. Because the temperature sensor module is attached to the lighting fixture, it can be conveniently set up in any part of the room and the temperature of each part can be measured and controlled.

The disadvantage of the next prior art described above is the complicated construction.

The task that the present utility model is intended to solve is to disinfect the air in various spaces without complicated, expensive devices.

The technical result achieved by solving the aforementioned task is that the luminaire with bactericidal disinfection function is easy to manufacture and assemble and has various functionalities.

The aforementioned technical result is achieved by a luminaire which has a body which is divided by protective light-shielding partition walls into a closed air disinfection room and a lighting part which are arranged one above the other. The air disinfection room includes openings for the entry and exit of air, which are arranged on opposite sides of the lower part of the body, light traps that make it more difficult for ultraviolet radiation to enter the room, at least one fan and one ultraviolet radiation source. The lighting part is provided with printed circuit boards with LEDs and a diffuser in the lower part of the body.

The ultraviolet radiation source can be an LED. The luminaire can also be equipped with a device for reactive power compensation.

The present utility model is executed as follows. The ceiling lamp consists of the through the light-shielding partitions 4th (please refer ) divided into an air disinfection room and a lighting part, which are arranged one above the other 1 (please refer ). The air disinfection room includes openings 9 for the entry and exit of air with light traps, which make it more difficult for UV rays to enter the room and on the edges of the face of the body 1 are arranged. At least one fan 6 (please refer ) and a UV radiation source 5 . The lighting part is with printed circuit boards with LEDs 7 and a diffuser 2nd in the lower part of the body 1 Mistake. The hatch is in the body 3rd and the power source 8th housed.

Two groups of openings 9 are intended for the intake of air from the room and the release of cleaned air into the room. Due to their shape and arrangement, mixing of the two streams is made more difficult and enables the device to function with maximum efficiency. The lighting part of the device covered by these groups of openings 9 is isolated is through the diffuser 2nd completed, which ensures a soft diffusion of the light from the LEDs without blinding effect.

The principle of operation of the present utility model is as follows. The bactericidal current from the UV radiation source is distributed to the small, closed space, which is located behind the visible part of the LED ceiling light; The air is disinfected as the air flows through with the help of the fans through the area with the UV radiation source. The body, the light-shielding partition walls and the special light traps at the entrance and exit of the device ensure reliable protection of people in the room against UV radiation.

The air is disinfected by the UV lamps or LEDs with a wavelength of 254 nm, which are able to clean the air of bacterial, viral and fungal pathogens.

The unique form factor of the device enables it to be quickly installed in any room with false ceiling by replacing any of the ceiling lights in the room. There is no need for any additional electrical installation measures that are related to the power supply. The degree of illumination on the work surface corresponds to the requirements of the SANPiN standard. The design of the device also enables easy replacement of the UV lamps.
