Reflector plays a very important role in industrial UV hardening technology. Only about 30% of the material is directly illuminated by the lamp tube, and about 70% of the material is reflected by the reflector<br>In general industrial UV hardening applications, most UV lamp sources use elliptical reflectors. The reason for the elliptical design is that the elliptical reflector basically has two focal points. The lamp tube is installed in the first focus, and the other focus is the position of the pre hardened object<br>Factors affecting complete hardening<br>Distribution of UV spectrum<br>Light intensity<br>Amount of UV light absorbent<br>The effect of oxygen<br>Infrared radiation<br>Film thickness<br>
