Abstract

An integrated solid-state lamp comprised of thermally conducting materials such as alumina ceramic or graphite filled polymers may simultaneously perform optical operations on the light emerging from solid-state emitters to enable the creation of a lamp which produces light in both direct and indirect light zones with a near-field uniformity more comparable to that produced by a vertical filament incandescent lamp. The light chamber structures may incorporate optical light path modifiers which push light into additional lighting zones for proximately omnidirectional light. Diffuser structures may incorporate hole patterns to improve thermal flow and light recycling efficiency. The distribution produced fully encompasses 0-180 deg. Light produced by the lamp chambers or atrium serve in like manner to the atrial chambers of the heart to produce light uniformly in all directions for general illumination at high efficiency.
