Abstract: Embodiments of a lamp that utilizes a reflector and a light source with light-emitting diode (LED) devices to generate an optical intensity distribution substantially similar to that of a conventional incandescent light bulb. These embodiments utilize an operation configuration with parameters that define relationships between components of the lamp to generate the optical intensity distribution. These parameters can, in one example, set out the position of the reflector relative to the light source as well as the ratio between dimensions of the reflector and the light source. In one embodiment, the reflector is in position relative to the light source to form a blocking area proximate the light source that defines a part of the lamp that does not diffuse light.
