A multi-level optical device that includes a housing. Further, a multi-level lightpipe is placed in the housing and includes at least two paths for passing light. A lightpipe barrier can optionally be placed between the at least two paths in the multi-level lightpipe, to provide enhanced separation between the light passing through the two paths. Further, a plurality of light emitting diodes (LEDs) are provided in the housing. Respective ones of the plurality of LEDs provide light input into a respective one of the paths of the multi-level lightpipe. The multi-level lightpipe can take the form of a bi-level prism, and the plurality of LEDs may be multi-color LEDs. A light-bleeding preventing device can be positioned between the at least two paths in the multi-level lightpipe. The multi-level lightpipe can also include plural multi-level lightpipes arranged in a row to create a matrix of output light signals.

A reflector device to be utilized with light emitting diodes (LEDs), and particularly with high-flux LEDs. In the reflector structure individual reflector portions surround at least one LED. Light output from each individual LED is reflected by sloping walls of each individual reflector portion and is redirected. As a result, light that may otherwise be lost is redirected to a more useful direction. Each individual reflector portion can have a cross-section of a conic shape, a complicated curve, and can also be oval in shape. A light device is realized by utilizing such a master reflector with an LED light source.

A light emitting diode (LED) light bulb that includes plural individual elements as sub-assembly elements of the overall light bulb. Different sub-assembly elements of a lens, a LED printed circuit board, a housing also functioning as a heat sink, a lower housing, and other individual sub-assembly components are utilized. The LED printed circuit board sub-assembly containing the LEDs can also be provided relatively close to a base.

Light emitting diode (LED) light bulbs

An obstruction lamp which replaces conventional incandescent light bulbs and which utilizes light emitting diodes (LEDs) in an illumination unit. The obstruction lamp includes a first plurality of LEDs connected in series. The first plurality of LEDs are mounted onto a metal vertical cylinder which provides a heat sinking for the first plurality of LEDs. A lens is configured to cover the first plurality of LEDs and the metal vertical cylinder. A metal base is provided on which the first plurality of LEDs, the metal vertical cylinder, and the lens are mounted. Further, a clamp is configured to seal the lens to the metal base. A second plurality of LEDs may be connected electrically independently of the first plurality of LEDs and may be mounted on top of the metal vertical cylinder. A wire housing may be configured to attach to the metal base and to provide electrical connection to the first and/or second plurality of LEDs. An adapter may be configured to attach to the metal base and to an existing incandescent obstruction lamp housing. The metal vertical cylinder can include driving circuit boards configured to drive the first and/or second plurality of LEDs. The first plurality of LEDs may be high power LEDs and the second plurality of LEDs may be lower power LEDs which are provided more for aesthetic purposes than for providing light output.
