Linear LED lamp
First Claim
1. A lamp comprising:
- a tubular enclosure having an electrical connection at an end; and
at least one array of LED devices electrically connected without a mechanical support structure and disposed in the tubular enclosure without being encapsulated to enable the lamp to emit light in all directions when the at least one array of LED devices is energized through the electrical connection; and
an optically transmissive, fluid medium contained in the enclosure in thermal communication with the at least one array of LED devices.

Abstract
A linear LED lamp is disclosed. Embodiments of the invention can provide an LED-based replacement lamp for a linear or “tube-type” bulb or a bulb with a linear filament or element. By filling the void within the lamp with an optically transmissive fluid to cool the LEDs without the use of a traditional heat sink, the light blocking effects of such a heat sink can be avoided. Thus, the LED replacement lamp can emit light in a substantially omnidirectional pattern. In some embodiments, the optically transmissive fluid medium is a liquid. In some embodiments, the optically transmissive fluid medium is a gel. An index matching medium can be used as the optically transmissive fluid medium. A color mixing treatment can optionally be included to eliminate color tints in cases where multiple LEDs of different colors are used to produce white light.

12. A lamp comprising:
-
an enclosure having an electrical connection at an end; a carrier; a plurality of LED devices disposed in the enclosure, the plurality of LED devices being connected without a mechanical support structure and without being encapsulated as a linear array so that light from the plurality of LED devices is emitted from the lamp in a substantially omnidirectional 360-degree pattern when the plurality of LED devices is energized through the electrical connection; and an optically transmissive, fluid medium contained in the enclosure in thermal communication with the plurality of LED devices. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
