Description

Method of manufacturing a light-active part of a luminaire with a protective layer of nanopolymers

Field of technology

The invention relates to a method of manufacturing a light-active part of a luminaire, which consists in applying a protective layer of nanopolymers to the light-active part of the luminaire. Specifically, this solution is used in all areas where it is necessary to use artificial lighting to perform the visual task, especially lighting areas with increased dust, or areas with increased incidence of bacteria and infections, or lighting areas where there is an increased possibility of fire or explosion. For the purposes of the present invention, the luminous active part of the luminaire is in particular covers, shades, lenses, reflectors, refractors, gratings, diffusers, etc. of the luminaires themselves, which are made in various shapes and sizes depending on the type, size and purpose of the luminaire. .

Prior art

Until now, the light-active parts of the luminaires have not been surface-treated in any way. As a result, dirt from air or dusty operations settles on the surface of the light-active parts. Removal of luminaires.

dirt from the surface is currently done by their mechanical removal - such as abrasion, washing or spraying. In case of insufficient or late mechanical removal of impurities from the light-active parts of the luminaires, there is a significant reduction in the luminous flux of the luminaire and thus a deterioration in the illumination of the visual task. The high financial demands associated with the removal of impurities from the surface of light-operated parts of luminaires and the possible need for a short-term shutdown of illuminated operations and premises during the removal of dirt from the surface of light-active parts of luminaires are also significant.

The essence of the invention

The object of the present invention is to eliminate said drawbacks by applying a protective layer of nanopolymer to the outer surface of the light-active part of the luminaire. The essence of the technical solution of the invention of applying the protective layer of nanopolymer on the outer surface of the light-active part of the luminaire lies in the technological process of applying the protective layer of nanopolymer, consisting of the following steps:

1) Perfect cleaning of the outer surface of the light-active part of the luminaire with an ionized gas stream, ie. eg cold plasma. The ionized gas stream is applied by a suitable means, eg by means of a plasma nozzle.

2) Uniform application of the protective layer of nanopolymers on the outer surface of the light-active part of the luminaire The layer of protective nanopolymers is applied in a thickness of 50 to 100 nm. The optimal strength of the protective layer of nanopolymers is 75 nm. The protective layer of nanopolymers is applied by means of a nozzle. The composition of the nanoparticle mixture itself, of which the nanopolymer layer is composed, is variable, i.e. a mixture with a primary dust repellent effect or a mixture which is antibacterial or a mixture which reduces the flammability of the light active part of the luminaire on which it is applied.

3) Curing of the protective layer of nanopolymers. Full cure occurs within 48 hours after application. For proper curing, it is necessary to keep the ambient temperature in the range of 25 to 30 ° C, relative humidity in the range of 40 to 60%, store the products in a dust-free space with atmospheric air pressure. For this purpose, the luminous parts of the luminaires shall, during this time, be placed in racks which are suitable for the shape and size of the luminous active part of the luminaire or otherwise suitably positioned to prevent contact with that part of the object on which the protective layer has been applied. i.e. the protective layer is free of contact with other bodies.

4) Polishing of the protective layer of nanopolymers, eg with a soft cloth. In this step, the excess from step 2 is removed and the outer surface of the light-active part of the luminaire is finalized and it acquires its final properties.

The protective layer of nanopolymers is hydrophobic, i.e. it repels water, in which dust particles are most often bound. By repelling (outflowing) polluted water, dust particles that are bound in the water are also removed. Furthermore, the protective layer of nanopolymers has antistatic effects, thanks to which dust particles are repelled. Thanks to this treatment of the luminous part of the luminaire, the presence of dust particles from air or dust on the surface of the luminous part of the luminaire is significantly reduced or the amount of bacteria and other undesirable microorganisms on the luminous part of the luminaire is reduced.

Thanks to the reduction of the amount of deposited dust or bacterial particles on the surface of the light-active part of the luminaire, the frequency of the need to clean the light-active parts of the luminaires is reduced. Thanks to the smaller deposition of dust and bacterial particles on the surface of the light-active part of the luminaire, there is also a significantly smaller decrease in the luminous flux of the luminaire. Not to be overlooked is the advantage of lower numbers of installed luminaires in the illuminated area, as well as the advantage of longer intervals of the need to clean the surfaces of light-active parts of the luminaires.
