Phototherapy method for treating psoriasis

Abstract

A system and method for phototherapy, including skin tanning, lupus phototherapy, teeth whitening, hair growth and psoriasis therapies, are provided. The system includes a chamber adapted for at least one type of phototherapy and at least one UV LED, at least one nanostructure UV light emitting device or a combination of UV LEDs and nanostructure UV light emitting devices.

1 .- 57 . (canceled) 
     
     
         58 . A system, comprising:
 a chamber; and   a light emitting device disposed in the chamber;   wherein:
 the light emitting device comprises a nanostructure light emitting device or a light emitting diode (LED); and 
 the light emitting device emits:
 a) light in a UV wavelength range suitable for performing lupus phototherapy; 
 b) light in a UV wavelength range suitable for performing psoriasis phototherapy; 
 c) light in a UV wavelength range suitable for inducing hair growth; or 
 d) light in a UV or blue wavelength range suitable for performing tooth whitening phototherapy in conjunction with a tooth whitening agent. 
 
   
     
     
         59 . The system of  claim 58 , wherein the chamber comprises a bed or a booth. 
     
     
         60 . The system of  claim 58 , wherein the light emitting device comprises at least one of a nanoparticle or a nanowire nanostructure UV light emitting device. 
     
     
         61 . The system of  claim 60 , further comprising a UV excitation source which is positioned to provide UV excitation radiation of a first peak wavelength onto the nanostructure UV light emitting device to cause the nanostructure UV light emitting device to emit UV light having a second UV peak wavelength longer than the first peak wavelength. 
     
     
         62 . The system of  claim 58 , wherein the light emitting device comprises a LED. 
     
     
         63 . The system of  claim 58 , wherein the light comprises light with a wavelength of about 340 nm to about 400 nm suitable for performing lupus phototherapy. 
     
     
         64 . The system of  claim 58 , wherein the light has an emission peak at or between 312 and 311 nm and a full width half maximum of about 0.1 to about 2 nm suitable for performing psoriasis phototherapy. 
     
     
         65 . The system of  claim 58 , wherein the light is suitable for inducing hair growth in conjunction with a hair growth assistance chemical which undergoes a hair growth stimulating reaction when exposed to the light. 
     
     
         66 . The system of  claim 58 , wherein the light comprises light in the UV or blue wavelength range suitable for performing tooth whitening phototherapy in conjunction with a tooth whitening agent. 
     
     
         67 . The system of  claim 58 , wherein the light emitting device is adapted to provide light having an adjustable wavelength range.
