Claims:

1. A UV steriliser assembly comprised of:

a UV source configured to emit ultraviolet light; and

a reflector associated with the UV source;

wherein the reflector is configured to permit or inhibit transmission therethrough of selected wavelengths of the ultraviolet light known to assist in the photo-repair of micro-organisms.

2. The UV steriliser assembly of claim 1 wherein the reflector is further configured to permit or inhibit transmission therethrough of selected wavelengths of the ultraviolet light known to be destructive to micro-organisms or neutral.

3. The UV steriliser assembly of any preceding claim wherein the reflector includes a dichroic coating formulated according to its light transmission properties for the seclected wavelengths.

4. The UV steriliser assembly of any preceding claim wherein the UV source is configured to emit a broad UV spectrum.

5. The UV steriliser assembly of any preceding claim wherein the reflector is further configured to permit or inhibit transmission therethrough of visible light.

6. The UV steriliser assembly of any preceding claim wherein the UV source is a Medium Pressure (MP) lamp.

7. The UV steriliser assembly of any preceding claim wherein the lamp is configured to excite mercury for producing a broad UV spectrum.

8. The UV steriliser assembly of any preceding claim wherein the UV source is doped to tune the ultraviolet light to remove or inhibit wavelengths known to assist in the photo-repair of micro-organisms.

9. The UV steriliser assembly of any preceding claim wherein the reflector is located adjacent or comprises an external wall of the steriliser assembly that, in use, is between the UV source and a media which is to be treated, and wherein the reflector is configured to inhibit transmission therethrough of selected wavelengths of the ultraviolet light known to assist in the photo-repair of micro-organisms.

10. The UV steriliser assembly of claim 9 wherein the reflector is formed on the surface of a tube within which the UV source is mounted.

11. The UV steriliser assembly of any preceding claim 1 to 8 wherein a total reflector is located opposite the reflector and wherein the reflector is configured to permit transmission therethrough of selected wavelengths of the ultraviolet light known to assist in the photo-repair of micro-organisms.

12. The UV steriliser assembly of claim 11 wherein either the reflector or the total reflector is elliptical.

13. The UV steriliser assembly of claim 11 wherein either the reflector or the total reflector is flat.

The UV steriliser assembly of claim 11 wherein either the reflector or the total reflector is concave to direct light away from the lamp.

A disinfection method including:

provision of a reflector with a coating or composition that permits or inhibits transmission therethrough of selected wavelengths of UV light known to assist in the photo-repair of micro-organisms;

arranging the reflector in combination with a broad spectrum UV source;

The disinfection method of claim 15 wherein a media to be treated by the method is either located in front of the reflector, when selected wavelengths are permitted; or behind the reflector, when selected wavelengths are inhibited.

The disinfection method of claim 15 or 16 wherein the coating or composition is a dichroic coating .

The disinfection method of claim 15 wherein the coating or composition also permits or inhibits transmission therethrough of selected wavelengths of UV light known to be destructive to micro-organisms.

The disinfection method of any preceding claim 15 to 18 wherein the reflector is formed on the surface of a tube within which the UV source is mounted, and wherein the reflector is configured to inhibit transmission therethrough of selected wavelengths of the ultraviolet light known to assist in the photo-repair of microorganisms.

The disinfection method of any preceding claim 15 to 18 wherein a total reflector is arranged opposite the reflector, and wherein the reflector is configured to permit transmission therethrough of selected wavelengths of the ultraviolet light known to assist in the photo-repair of micro-organisms.

The disinfection method of claim 20 wherein either the reflector or the total reflector is elliptical.

The disinfection method of claim 20 wherein either the reflector or the total reflector is flat.

The disinfection method of claim 20 wherein either the reflector or the total reflector is concave to direct light away from the UV source.

The disinfection method of any preceding claim 15 to 23 wherein the UV source is doped to tune the ultraviolet light to remove or inhibit wavelengths known to assist in the photo-repair of micro-organisms.

A UV light assembly comprised of:

a UV source configured to emit ultraviolet light of a range of wavelengths; and

a reflector associated with the UV source;

wherein the reflector is configured to permit or inhibit transmission therethrough of targeted wavelengths of light associated with a photo-chemical process.
