Abstract
A light source enhancing lens assembly 10 has a carrier 20, a light source 30 carried by the carrier 20, a first lens 40 which refracts and diffuses light emitted from the light source 30 and a second lens 70 to defocus and further distribute the light emitting from the first lens 40. The light source 30 is inserted into the first lens 40, so that light from the LED is refracted within a first bore 48 and diffused by a frosted first outer surface 60 of the first lens 40. The first lens 40 inserts into a second bore 40 of the second lens 70. Light from the first lens 40 is further defocused by a series of parallel, spaced apart lens sections 82 located on the second outer surface 78 of the second lens 70.
Claims33
A lens assembly for evenly distributing light from a light source, comprising:
- a first lens having a first outer surface, said first lens having a distribution means for refracting and diffusing light;
- and
- a second lens in spaced relation to said first lens and having a second outer surface, said second lens having means for defocusing light emitted by said first lens, wherein said second outer surface has a plurality of parallel, spaced apart lens sections formed thereon.
A light assembly for evenly distributing light from a light source, comprising:
- a first lens having a first end and an opposing second end and a first bore formed therein, and wherein said second end of said first lens is hyperbolically shaped;
- a second lens having a second bore formed therein, said first lens being carried within said second bore;
- and
- a light source carried within said first bore.
A light assembly for evenly distributing light from a light source, comprising:
- a light emitting diode having an output of at least 6000 mcd;
- a first lens having a first outer surface, said first lens having a first bore dimensioned to receive said light emitting diode;
- and
- a second lens having a second bore dimensioned to receive said first lens.
A lens assembly for evenly distributing light from a light source, comprising:
- a first lens having a first outer surface, said first lens having a distribution means for refracting and diffusing light;
- and
- a second lens in spaced relation to said first lens and having a second outer surface, said second lens having means for defocusing light emitted by said first lens, wherein said second lens has a bore formed therein that has a bore end, said bore end being hyperbolically-shaped.
A lens assembly for evenly distributing light from a light source, comprising:
- a first lens having a first outer surface, said first lens having a distribution means for refracting and diffusing light;
- and
- a second lens in spaced relation to said first lens and having a second outer surface, said second lens having means for defocusing light emitted by said first lens, wherein said first lens has a bore formed therein that has a bore end, said bore end being hemispherically shaped.
A light assembly for evenly distributing light from a light source, comprising:
- a carrier;
- a light emitting diode having an output of at least 6000 mcd carried by said carrier;
- and
- a lens carried by said carrier and having a convex-shaped, cylindrical body and an outer surface, said lens having a first bore formed therein and dimensioned to receive said light emitting diode, said first bore having a bore end.
