Description
Narrow band UVB lamps,this lamp emit ultraviolet rays between 280nm and 360nm(at peak 360nm),the special energy suitable to test the ultraviolet resistance of paints,plastics and rubbers They also mainly used for the special light sources for inspection and medical analysis or the treatment of dermatosis.

UVB Narrowband Phototherapy Lamp Technology

A UVB narrow band lamp emits light energy.  Narrowband UVB phototherapy (UVB-NB) comprises a subset of the UVB wideband, or broadband, spectrum centered at roughly 311 nm. This is less than 1% of total range of wavelengths from sunlight. Narrow band UVB has been shown to be the optimal part of the UV light spectrum which slows growth of psoriasis lesions.  Since the narrowband wavelength is shorter than broadband, exposure time to narrow band UVB phototherapy treatment lights can be increased. The result is powerful targeted phototherapy treatment.

Another clear advantage of narrowband UVB is that skin is most sensitive to erythemic response, (sun burning) at 297 nm, so narrow band phototherapy nearly eliminates this problem .

UVB Narrow Band causes less sun burning or erythemal effect than other treatments such as UVB Broadband. The chart above shows that the skin's erythemal (sun burning sensitivity) is at its max at around 297 nm and that UVB NB with it's spectra centered around 311-313 nm generates very low erythemal response. This allows the user to have longer treatment times before "seeing" an erythemal response. UVB NB is fast becoming the recommended treatment to replace Broadband UVB and PUVA. Most of sales today are UVB Narrow Band units.

Clinical studies have shown that the peak therapeutic effectiveness of UVB to be between 295 to 313 nm and that wavelengths below (shorter) than roughly 300 nm are more likely to cause a strong erythemal response or severe burning. UVB Narrow Band is in the 311-313 nm range and causes less burning than shorter wavelengths.
