Video that shows you changing beam angle by using convex Fresnel and concave fresnel
Août 31, 2016
We made a vedio to show you the difference between convex(or conversing) lens and concave(or diverging) lens.
We shot the process. Experimental equipment Conversing Fresnel lens (DIYPRO product) Diverging Fresnel lens (DIYPRO product) Light Source using COB LED - Xicato The beam angle of Jigato module is 120 dgrees when nothing is applied.
First, it is what shown you when convex is applied.
Second, it shows you what spread again by usinsg concave.
You can see the light distribution angle changed depending on the movement of lens.
