最近在看UL1993,有两个定义,我看了不是很清楚,请教一下各位大佬们: LED LENS, INTEGRAL – the optical element integral to an LED package that focuses or diffuses the light from the LED die(s). Optical assemblies secured to the LED package after package manufacture (such as during the assembly of an LED array) are not considered integral LED lenses.

LED LENS, INTEGRAL与Diffuser的区别是什么?一般LED球泡灯中,哪一部分是LENS,哪一部分是DIFFUSER?
