UV / led Light Emitting Diode for NB inkjet printer
UV light emitting diode means that wave length in range of ultra violet area and in 320-400 nano meters by which we call it UVA. Comparatively this wave length of UVA is longer than other UV lights as well as lower absorption of nucleic acid and protein so that it is an UV light with less harm to all organisms.
UV led can be used as white LED for lighting, we can use UV to excite different fluorescent powder to initiate 3 lights in red / green / blue color then forming the white light which is good and soft for human eyes and excellent for making white led. The point is no high enough lighting efficient led UV in the industry for this purpose by now, this is facing the same technology needs new development of led UV as for our NozzleBlack ctp printers, small but strong, light in weight good for mounting on the inkjet printer for direct curing or exposure after spray.
