Ways of controlling beam angles

Posted By: admin on Sep 06, 2012 in Knowledge base

WELLMAX controls beam angles with the subsequent methods:

A. HIGH POWER LED Lights. The angle determined by the frame, lens, or mold.The angle depends on the depth of the frame cup,while for that lens and mold,there are a variety of angles to choose, like 120 °, 140 ° or 160 °.

B. DIP led:Controlled by the mold bar and frame,the deeper lamp cup,and the smaller angle.Additionally, for the same mold bar, larger card it is, small angle it will be.

C. SMD led. The angle of SMD LED is a  bit special,usually,decided by its frame,the angles are different,there is little change space to be adjusted: less glue,the angle will be bigger , and the other way around. Usually we use the half-power angle as it when the lamp luminous intensity reaches 50%, sometimes choose 60%, 80% or even 90% ,which depends on the different application occasions.
