LENS OF LIGHTING APPARATUS

摘要

PURPOSE: A lens for a lighting device increases the installation interval between LED lighting devices by delivering light emitted from an LED to its maximum distance. CONSTITUTION: A lens for a lighting device includes a main body (21), an incident part (23), an output part (25), and a connection part (22). The main body covers an LED light source (10). The incident part includes first to third shape parts (231,233,235) formed on a lower part, which receives light emitted from the LED light source, in the main body to control an orientation angle of the light. The output part is formed outside the main body and includes multiple curved surface parts having different curvatures to emit the light by controlling the refraction of the light. The connection part attaches the lens to the LED light source.
