该灯光谱有效范围在350-450nm之间，主波峰为365nm，有700多个品种，功率在100w-25kw。UV固化广泛用于竹木地板、家俱、装饰材料、印刷上光、印铁制罐、塑胶涂装等行业；也是半导体、标牌、电路板、电子元件的光敏油墨固化；更有理想点光源，便携式光源及实验室专用光源可供选择。
UV灯为气体放电灯，气体放电灯分为弧光放电和辉光放电，UV固化中常用UV灯为弧光放电灯，其工作原理是：在真空的石英管中加入定量的高纯汞（水银），通过对两端电极提供电压差（压降），产生离子放电，从而产生紫外线辐射。
UV灯专业用于各种UV涂料、UV油墨、UV上光油、UV胶水的干燥固化。其优点是：固化速度快，光泽度高，固化产品表面附着力强。
适用领域为：印刷制版、软包装彩印、家俱行业、装饰材料、纸张上光、汽车及摩托塑料零件、印刷制罐、塑料包装表面UV油墨、UV上光油固化、同时还是半导体印制线路板、标牌、光等上面的光敏阻焊剂及光敏字符油墨交连固化的理想光源。
Ultraviolet ray high pressure mercury lamp (uv-A), is selects the
lamp case which thoroughly the purple rate very strong pure quartz
glass makes, the lamp when the work the ultraviolet radiation wave
length for (350nm-420nm) take 365nm as a center, suitably and each
kind of ultraviolet ray solidifies in the lamphouse in the
ultraviolet ray solidification machine, widely applies in the
printed wiring board photosensitive anti- solder solidification,
the photosensitive character printing ink, the photosensitive litho
ink solidifies, is also the PVC formica dye printing printing ink
solidifies, the wood floor photosensitive resin UV paint coating
solidifies, the processed foods color printing, on the plastic
bottle cap and each kind of work piece's photosensitive printing
ink, the photosensitive paint and the photosensitive resin solidify
the most ideal photo source, this lamp ultra-violet rays radiation
intensity is high, lifeIs long, is quick to each photosensitive
material curing velocity, does not have the pollution.
