An incandescent electric lamp having an envelope and means for reflecting infrared energy back to the filament to increase its operating temperature while transmitting visible energy. The envelope is shaped to reflect the infrared energy back to the filament and the filament is purposely misaligned with respect to the optical center of the envelope so that the infrared energy impinges on the filament after two reflections from the envelope wall.

An energy-efficient lamp having a waveguide mounted to the envelope of the lamp which may be of the incandescent type. The waveguide passes visible radiation and reflects infrared radiation. The waveguide may be a reticulated layer of an electrically conductive material such as silver and the reticulations may be regularly or irregularly distributed over the surface of the envelope.

An incandescent electric lamp having a filament which incandesces and produces a vapor of the metal of the filament which normally deposits on the wall. A coating is placed on the filament wall where the majority of the vapor would normally deposit to act as a reflecting coating so that the visible energy reflected from the coating will be transmitted through a portion of the wall which is not blackened by the vapor. The coating thickness is adjusted so that the deposit from the filament builds up on a nodal surface so that light absorption is small.

An incandescent lamp utilizing a transparent heat mirror coating on the lamp envelope for transmitting radiation in a selected portion of the visible range to produce a desired color and reflecting infrared thermal radiation back to the filament for increasing its temperature and thereby increasing its efficiency. The coating is preferably of the etalon type having a layer of an insulating material sandwiched between two layers of metal.

An incandescent electric having a filament which incandesces and produces a vapor of the metal of the filament which normally deposits on the envelope wall. Structures are provided adjacent the filament on which vaporized filament material will deposit rather than deposit on the envelope wall where it would reduce the light output of the lamp.

An incandescent lamp of a type in which infrared (IR) energy is to be reflected back to the filament. The lamp has one section which is coated with an IR reflecting material which also will transmit visible light and another section coated with material which has a high reflectivity to IR energy and a low transmissivity to visible light. The filament is mounted off-center of the optical image axis of the envelope and substantially all of the energy in the visible light range exits from the envelope in no more than two passes.

In accordance with the present invention, a laser device is formed on an integrated circuit substrate, such as a silicon chip by sandwiching a thin-film amorphous semiconductor between reflective electrodes. The upper electrode is made only partially reflective so that, when an operating potential is applied between the electrodes, a stimulated emission of light energy in the infrared range is observed and this emission occurs through the upper electrode. To form a light amplifier, the lower reflecting electrode is omitted, so that the amorphous semiconductor and the substrate form a heterojunction which has low infrared reflectivity. In operating the amplifier, a potential is applied between the upper electrode and the substrate to control amplification. Incident radiation passes through the upper electrode and into the amorphous semiconductor and substrate and, in the process, is amplified in accordance with the value of the applied potential. This permits the incident radiation to be modulated in accordance with the applied potential.

An incandescent electric lamp having a coating to reflect infrared energy back to the filament to raise its operating temperature in which the envelope is shaped as an ellipsoid and the filament and envelope have a relationship to reduce losses due to aberration and to produce a more uniform temperature distribution along the filament.
