UV-LED 光源特点

特点

1、冷光源,无热辐射,适用于热敏材料的粘接

2、即开机关,无需预热,照射强度可达8000mW/平方厘米以上

3、外形小巧,使得设备能轻而易举的整合到全自动生产线和设备中

4、UV LED无红外辐射,无有害气体产生,符合ROHS标准。相对传统汞灯更安全、更环保

5、寿命达20000小时以上,可大幅削减运行成本和维护工时

6、连接线为耐弯曲电缆,随意安装在可动部,满足反复移动的需要

优点

冷光源、无热辐射,被照物品表面温升低,解决光通讯、液晶生产中长期存在的热伤害问题,特别适合液晶封边、薄膜印刷等要求温升小的场合适用。发热量小,可解决汞灯喷绘设备发热量大、工作人员难以忍受的问题。并且,LED-UV光源,发出的是高纯度单波段紫外光,几乎没有红外线的输出,它属于冷光源,加工件不会因受热而变形。

效率高:LED-UV的光线能量高度集中在具有有效固化作用的某紫外光谱段,实际使用效果和光强为1000-2000mw/cm2的传统高压汞灯UV光源的固化效果不相上下,从而使固化时间缩短。传统的汞灯UV光看上去亮度很高,但热量很高,因为它的光谱很宽,真正起有效固化作用的紫外光谱段只占其中的一部份能量,有相当大一部份是在可见光段(杂光)和红外光谱度(导致热量产生),对操作者的眼睛损伤严重并且容易使加工工件热变形。

(1)超长寿命:LED-UV灯的使用寿命是传统汞灯的10倍以上,且使用寿命不受开关次数影响。

(2)瞬间开关,不需要预热即可达到最大功率紫外输出,关闭后可以瞬间重新开机。

(3)能量高,光输出稳定,照射均匀效果好,提高生产效率。

(4)可定制有效照射区域,长度从20mm到2000mm。

(5)不含汞,也不会产生臭氧,是替代传统光源技术的一种更安全,更环保的选择。

(6)能耗低,耗电量仅为传统汞灯式固化机的10%,能节约90%电量。

(7)维护成本几乎为零,采用UV-LED固化设备每年至少节约10000元/台的耗材费。

(8)由于紫外线照射装置与相关配套装置非常紧凑,无需以往那种较大的机械安装空间以及管道施工,设置简单容易。可以说LED-UV固化系统进一步增强了传统UV固化系统的环境协调生。LED-UV技术是原有UV技术的升级。

UV-LED light source characteristics

Characteristic

1,cold light source,no heat radiation

2,is open,without preheating,irradiation intensity of up to 8000mW/cm2

3,compact,making the device can be easily integrated into the automatic production line and equipment

4,UV LED no infrared radiation,no harmful gas production,in line with the ROHS standard.Compared with traditional mercury lamp,it is safer and more environmentally friendly

5,life of more than 20000 hours,can significantly reduce operating costs and maintenance of working hours

6,the connecting line is a bending resistant cable,which can be installed in the movable part at will,so as to meet the need of repeated movement 

Advantage

.Cold light source,no heat radiation:the illuminated objest surface temperature low,to solve the long-standing problem of thermal damage of optical communication,LCD production,especially suitable for liquid crystal sealing,film printing requirements of small temperature rise where applicable.The utility model has the aduvantages of small calorific value,and can solve the problems of large heat quantity of the mercury lamp spraying equipment and the difficulty of the staff.Moreover,the LED-UV light source,is issued by the high purity single band ultraviolet light,almost no infrared output,it belongs to the cold light source,the workpiece will not be deformed by heat.

.High efficiency:LED-UV-ray energy is highly concentrated in the effective curing effect of a UV curing effect,be roughly the same practical effect and intensity for the traditional high pressure mercury lamp UV light source is 1000-2000mW/cm2,so as to shorten the curing time.The traditional UV lamp light looks brightness is high,but the heat is high,because of its wide spectrum,the real part of the UV spectrum effective cure only accounted for a large part of the energy is in the visible range(stray light and infrared spectra fo(LED)heat production)the damage to the operator's eyes,serious and easy to make the workpiece deformation.

(1)the service life of the LED-UV lamp is more than 10 times that of the traditional mercury lamp,and the service life is not affected by the switching frequency.

(2)instantaneous switch,the maximum power output can be achieved without preheating.

(3)the energy is high,the light output is stable,the irradiation uniformity effect is good,and the production efficiency is improved.

(4)can be customized effective radiation area,length from 20mm to 2000mm.

(5)it is a safer and more environmentally friendly alternative to conventional light sources without mercury.

(6)low energy and more environmentally friendly alternative to conventional light sources without mercury.

(7)maintenance costs are almost zero,the use of UV-LED curing equipment to save at least $10000 per year / Taiwan supplies costs.

(8)because the ultrviolet irradiation device and the relevant supporting device are very compact,the utility model has the advantages of no need of the larger mechanical installation space and pipeline construction. It can be said that LED-UV curing system has further enhanced the environmental coordination of traditional UV curing system.LED-UV technology is the upgrading of the oringinal UV technology.
