In this regard, the spacing between LEDs may vary depending upon the diameter of the tube 22 to which the light strip 25 is to be applied.
  • the LEDs of the present invention are blue light emitting LEDs 34. Blue light emitting LEDs are able to perform a disinfecting procedure. In this regard, blue light is generally light in the spectral range of 405 nm - 450 nm and is part of the visible light spectrum. It is known that microbes, such as bacteria, viruses and the like, contain photo-sensitive compounds inside their cells that are capable of absorbing light and using the light energy to produce enzymes or proteins that boost their growth and vitality. However, when microbes are exposed to blue light at a predetermined density, it is established that the chemical reaction generated within the cells produces different types of reactive oxygen radicals, typically referred to as free radicals. These free radicals are very reactive and can destroy the microbe from the inside, this killing the microbes and performing a disinfection procedure.
  • UV light is less harmful than Ultraviolet (UV) light, which is part of the non- visible light spectrum.
  • UV light is made up of short wavelengths of light, and whilst its germicidal effects are well known, UV light has harmful effects on humans and has a propensity to damage devices made of plastics and polycarbon materials.
