PRISM ILLUMINATION DEVICE FOR LED

摘要

PURPOSE: A prism lighting device for an LED is provided to suppress the overlap of light and control a light approaching region and a non-light approaching region by selectively emitting light with a desirable angle. CONSTITUTION: A pillar(10) is installed with a preset height. A prism is comprised of a plurality of bands along the outside of the pillar and has a groove to receive an LED. A plurality of LEDs are received in the groove of the upper side of the prism with a band type. A cover(30) is located on the upper side of the pillar and is installed on the upper side of the prism with the LED to fix the prism. The lower side of the prism has a specific pattern to concentrate and scatter light in a specific direction without the light interference of adjacent bands.
