FIBRE OPTIC ULTRA VIOLET WATER TREATMENT SYSTEM
Field of Invention This invention relates tc~ a complete fibre; optic lighting system for the use of water p~u-ification and sterilization .'i'~e system can be used in small home settings or in large cotnme~°cral applications.Use of the fibre optics allows the light sc'urce and <~tteradant heat combined with electricity to be located from the treated area.l~'l~is provides for consistent light treatment and reduced need for specialized units in the areas of U.V
light tranmission.
Background of the inventioy With U.V light , light , temperature , can be precisely controlled to create the pertect atmosphere; for° sterilization and purification.
Of the elements U.V light in the proper wavelength area is critical.Natural light is an optimum light in the area of u.v as in sunlight however in many areas an artificial supplement of' u.v in a higher range can be accomplished.
Natural light and artificial Light have clifterent wavelengths or spectral qualities.There are many different types c>f" artificial light depending on the light source used and tile character~isti~s.'l~'h~ spectral characteristics can be altered or enchaa~ced by the use of filterws , coatings or other means.Nornaally the violet ~blu~; segments of tlve spectrum are most important for sterilization arid puri~ic;atior~ p~~ocluctic:~n.
A plethora of lighting systems for ~_i.~' sterilization and purification are currently in use.ln almost all cases ~:~ high amount of light output results in considerable heat geioerated near tkie source.As renuired, the light source can be placed close to the treated area. Si,~,mificant temperatLire change developer near the water v~lhiclx can produce dangerous results.Light sources that have been used in the past include flourescent u.v lighting, high or to rv pressure lights and variety of others.
Often times water lighting systems must deal with excessive heat produced by existing technolog-ies.V~lat~r lighting systems allow the placing of light sources close to the treatnierit ar~ea.'l"he drawback is the heat build. up around the light in conjuctior~ with electricity is detremental.
This light intensity is very high to ensure the noaximum rage of sterilization and purification will occur. i'he water jacket enclosure surrounds the bulb and absorbs a percentage ol' lJ. V to tile treatnnent area.The result. is a reduction of light output throu~:h tl~e surface.
Many disadvantages of the current syste~°ns are heat output , complexity , cost, and difficulty of' maintenence with operations. Heat values with electricity are tire r~~ost problematic.
The present invention. seeks tc~ improve on existing L1.V light systems for water sterilization or puribcation.'l'he ability to locate the light source , and thus the heat or electricity generation remotely from the area. This is accomplished by the use of' U.'V fibreoptic light transmission systems which transmit specialized light produced firom projection type bulbs through u.v emmiting cabling into customized sealed units.
Major advantages is that ttie natural elements contained are not altered and provide purity at a safe level. l~estructicm of pathogens and other contaminents is completed whets tile ultra violet fully encompasses or penetrates the enclosed area.
Obiects of the invention It is an object of the invention to provide an improved lighting system for water purification and sterilization.
It is a frtrther object of the invention tc~ provide a lighting system using fibre optics to allow flexibiity of the light deliverance.
It is a further object of the inve~~tic~n to provide a lighting system that is capable of locating the light source outside the treatment area.
