Honeycomb surface Lambertian light distribution

Longman employs a variety of optical technologies, with secondary light distribution lenses mainly in honeycomb surface, semi-honeycomb surface, double-layer honeycomb surface, frosted surface, and clear surface, covering a beam angle of 2.5 degrees (50% light intensity) to 120 degrees, and a spotlight angle of 5 degrees (10% light intensity) to 180 degrees. While providing uniform color mixing at various angles, it also meets the axial light distribution efficiency of (2.5 - 30.5) cd/lm.
