ASYMMETRIC HEMISPHERE DIFFUSION LENS FOR ELECTRIC SIGN-BOARD AND DIFFUSION LENS ARRAY

摘要

PURPOSE: the display panel of asymmetric hemispherical diffusion eyeglass and diverging lens array board improves the luminous luminescence unit of luminous efficiency, passes through the lens in control or radiation angular region. ;CONSTITUTION: hemispherical spreads the display panel that luminescence unit (2) are arranged before eyeglass (3). The transmitting light of hemispherical diverging lens diffuses through transfer surface. Plane at the center of vertex transmission plane tilted upward. Planar top forms transmission surface. Multiple asymmetry hemispherical diverging lens are arranged in diverging lens array board. The light of irradiating angle can be by adjusting fixed position transmitting unit. ;The 2011 of copyright KIPO submissions
