Light pipes and associated assemblies with uniform illumination and high efficiency

A light pipe, comprising:

• a body comprising:
• a front face with an exit ring configured to emit light;
• a rear face with at least two light channels configured to receive and direct light from at least two respective light emitting diodes (LEDs) to the exit ring, the at least two light channels extending at least partially circumferentially around the body;
• and
• an annular surface that extends around an outer circumference of the rear face, the annular surface configured to reflect light toward the exit ring;
• wherein the annular surface comprises a chamfered surface that is angled relative to the rear face, the chamfered surface configured to reflect light from the at least two light channels toward the exit ring.

A method of forming a light pipe assembly, comprising:

• assembling a printed circuit board assembly (PCBA) to a rear face of a light pipe;
• wherein the PCBA includes at least two light emitting diodes (LEDs);
• wherein the light pipe includes a front face with an exit ring, and a rear face with at least two light channels and an annular surface configured to reflect light to the exit ring, the at least two light channels extending at least partially circumferentially around the light pipe;
• and
• wherein the at least two light channels are configured to receive and direct light from respective LEDs of the at least two LEDs to the exit ring via the annular surface;
• and
• wherein the annular surface comprises a chamfered surface that is angled relative to the rear face, the chamfered surface configured to reflect light from the at least two light channels toward the exit ring.
