REFLECTOR AND LAMP COMPRISED THEREOF

摘要

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.

主权项

1. A lamp with a central axis, comprising:
an envelope forming an interior volume; a reflector disposed in the interior volume at a reflector plane that is tangent to at least two points on the reflector; and a light source that is configured to generate light onto the reflector, wherein the reflector and the light source each have a profile with an outer profile dimension that forms a reflector-to-light source size ratio in a range of from about 2.8 to about 3.6.
