The conception of uv led strip light energy & power density

l                Light energy : light energy refer to The variation of the light distribution in object or space. The uv light energy is now express in MJ/CM2 ，the light energy integrator are used for measuring light energy. Some factory indicates irradiation range with light energy. In generally , the curing condition shall meets that (800-1200)MJ/CM2。Other way equipped with shell uv led is not applicable to this case..

l                The power density of uv led mean by power is required between two centers of the UV led . represents with W/CM .
