Main use: Vitiligo (vitligo), psoriasis, psoriasis psoriasis (psoriasis), psoriasis and other skin ultraviolet light therapy; 
 Philips (Philips) narrow-band UVB lamp wavelength range: 
 Narrow-band UVB 300nm-320nm, peak 311nm. 
 Mainly applies to the following several treatment instrument: 
 (1). "Beijing Purple letter" NB-UVB treatment of hand-held device; 
 (2). "German Waldmann (Warman)" UV109B hand therapy light bar; 
 (3). "Shanghai Sigma" SS-01B-type (narrow-band UVB) light therapy device.

 First look at nb-uvb 
 Narrow Bound Ultra Violet B Light (NB-UVB) for the treatment of psoriasis, psoriasis psoriasis (psoriasis), vitiligo (vitligo) is a front-end technology. In the past, most doctors are using PUVA equipment, this method requires taking psoralen PUVA therapy combined with medication, but his side is that most people can not stand the NB_UVB research team members released by maximizing narrow band UVB rays minimal skin exposure to UV rays in the other redundant, thereby solving the above problems. (Wavelength 311nm --- 312nm is the most effective natural sun part). 
 This greatly reduces the use of optical therapy vit patients were likely to UV damage. (Also avoid taking the conventional psoralen PUVA treatment of drug side effects, because NBUVB without any adjuvant) were the majority of these make NB_UVB doctors and patients and the popularity of vit. 
 At the same time, NB_UVB can use in the family, which also facilitates the treatment of vit. As for how to choose NBUVB the device type, exposure distance, exposure time, dosage according to each person's specific circumstances. 
 NB_UVB through the release of effective wavelength (311nm-312nm) UV, eliminating excessive and other harmful ultraviolet rays, while the traditional UVB light rays emitted range (280nm-330nm). Clinical studies have shown that the most effective treatment vit-ray wavelength was 295nm - 313nm, but if the wavelengths below 300nm, are likely to lead to skin cancer, burns, or other diseases, 311nm - 312nm is considered the most safe range.
