Abstract

The present invention provides a lamp that includes: an LED light source; a lens having an incident surface and an emergent surface, the incident surface defining a first cavity, and the emergent surface having an annular protuberance thereon; and a light filter device accommodated within a space defined by the annular protuberance of the lens, wherein, the LED light source is situated within or proximate to the first cavity, to enable light emitted from the LED light source entering the lens from the incident surface and exiting the lens from the emergent surface to be at least partially transmitted through the light filter device.
