AVIATION WARNING LIGHT WITH ASYMMETRY ANGULAR DISTRIBUTION OF LUMINOUS INTENSITY

摘要

An object of the present invention is to provide an airborne obstacle having an asymmetric angle of divergence which forms a divergence angle at which light irradiated from a light source section is output in a horizontal direction or an upward direction of an optical axis. The present invention provides a portable terminal comprising: a housing having a storage space therein; A light source installed in the housing to emit light; And a lens unit installed around the housing to form a light-distribution angle such that light emitted from the light source unit is radiated to the horizontal direction and the horizontal direction of the optical axis. Therefore, the present invention can improve the luminous efficiency by forming a diffraction angle at which the light emitted from the light source unit is output in the horizontal direction or the upward direction of the optical axis, and can prevent the light pollution by blocking the light emitted in the downward direction .
