Direct-Lit Lens used in BLUs (Backlight Units) should be available in achieving high light diffusion level and uniform illumination for suitable LEDs.
Interior Lighting Panels, which used only LEDs as light source, is following the trend of using diffusion lens. For other interior lighting, streetlights and tunnel lamps, demand on suitable lens is increasing.
Diffusion lenses for LEDs are increasingly popular for outdoor digital signage , which require highest level of visibility and uniformity.
Diffusion lenses are increasingly used for Automotive CIDs (Center Information Display), and various lenses are also used for indoor lighting and logo lamps of cars.
