摘要
A lamp comprising a light-transmissive envelope, the inner surface of which is only partially coated by a reflective barrier coating layer such that an aperture is created in the coating for light emission, the lamp exhibiting asymmetric light output through the aperture and lumens substantially equivalent to a lamp wherein the envelope inner surface is completely coated with a reflective barrier coating layer having no aperture, and a laser ablation process for creating the reflective barrier coating layer aperture.
