UV point light source curing machine is good for high-pressure mercury lamp source, or is it good for LED light source?
UV-LED point light source, a high purity 365nm monochromatic ultraviolet light, which belongs to the cold light source; the workpiece temperature rose by only 3 degrees, not deformation processing, its energy is highly concentrated in a effective curing effect of a UV curing effect, be roughly the same HPML actual use effect and intensity of 1000-2000mw, shorten the curing time from 0.5 to 5 seconds.
From the traditional curing machine UV looks very bright light brightness, high calorie, in fact it is very wide spectrum, a UV curing mechanism is really effective for only a part of energy, a large part is in the visible range (stray light) and produce heat, eye damage to the operator serious and easy to make the workpiece deformation.
There are two forms of UV LED point light source: UV, mercury lamp and UVLEDWell, definitely UVLED light source, UVLED light source advantages, costs are almost the same.UV mercury lamp:The UV point light source of UV mercury lamp needs the transmission of UV ray tube, and the light transmission rate of the good UV light guide tube is less than 100%, and the 70-80% is very good. The others must have been wasted. UV point light source UV mercury lamp do not cost low and is the flagship of imported equipment, UV light power and UVLED nature is the same, and should be roughly the same lens but UV lamp life, and power consumption and ozone emissions are not the way to solve problems. UV point light source mercury lamp price is not cheap.UVLED light source:A single lamp light irradiation, UV optical power can only improve the UV light intensity of single bulb. The lens is much better than the UV mercury lamp, and has the advantages of life and energy saving, and the cost will not be higher than that of the UV mercury lamp.Difference: the UV mercury lamp is the light guide tube output, and the UVLED is the direct irradiation head.
