Patent ID: 7161186

Claim:
A sideway-emission light emitting diode comprising: at least one sideway-emission light emitting diode structure, each of the at least one sideway-emission light emitting diode structure having: a) at least one light emitting diode package, each package of the at least one light emitting diode package having: i) a light emitting diode die transmitting a light; and ii) a lens positioned overthe light emitting diode die and receiving and redirecting the light toward a circumference of the package; and b) a light guide having: i) a cavity located in a center thereof, each of the at least one light emitting diode package is located in the cavity; ii) a first pair of opposing sides, each of the first pair of opposing sides is a refraction section and has two straight side portions and an angled cut-off located in a middle portion thereof between the two straight side portions, each angled cut-off has two inclined edges sloping outwardly with a predetermined angle there between; and iii) a second pair of opposing sides, each of the second pair of opposing sides has a projection section, ends of the first pair of opposing sides are located adjacent to ends of the second pair of opposing sides, wherein the refraction section reflecting the light toward the projection section, the light is released from the projection section.
