Patent ID: 7738189

Claim:
A side emitting lens, comprising: a body, wherein the body comprises: a base part on which external light is incident, a refracting part to refract incident light and emit light from side surfaces of the lens, and a reflecting part in the shape of a conical recess at a central portion of the refracting part to fully reflect the incident light toward at least one of the refracting part and the base part, the reflecting part comprising two or more reflecting surfaces, wherein at least two of the two or more reflecting surfaces are curved surfaces, wherein the reflecting part comprises a first reflecting surface and a second reflecting surface, wherein the refracting part comprises: a first refracting surface adjacent to the second reflecting surface, a third refracting surface adjacent to the base part, and a second refracting surface formed between the first refracting surface and the third refracting surface, wherein each of the first reflecting surface, second reflecting surface, and second refracting surface is a curved surface, wherein each of the first refracting surface and third refracting surface is a flat surface, and wherein each of the first refracting surface and third refracting surface is inclined with respect to the base part.
