Abstract
A light emitting diode (LED) based lamp is provided that may include a housing, a LED module having at least one LED to emit light, and a lens to receive the light from the LED and to guide the light to a specific area. An outer circumference of the lens may have a different surface roughness than an inner surface of the lens or may have a different light transmissivity than the inner surface of the lens. The outer circumference of the lens may minimize light from being transmitted to a region outside the specific area.
