Chlorophyll a absorbs violet (high-energy; max. 372 nm) and orange light (low-energy; max. 642 nm) the most; the mid-point being 507 nm. Chlorophyll b absorbs mostly blue (high energy; max. 392 nm) and yellow (low-energy; max. 626 nm) light; the mid-point being 509 nm. They both also absorb light of other wavelengths with less intensity. Both mid-points are nearly identical to the mid-point between energy and entropy maximum of scattered sunlight. The claimed microelectronic device provides radiation for artificial lighting applications from ruthenium vapor in the blue and deep red region. The entropy (heat) generated by inefficiencies in p-n junction recombination and luminescent materials' Stokes shift is transferred to the thermodynamic heats of evaporation and sublimation of rubidium atoms. The microelectronic device eliminates the need for external cooling of indoor greenhouse environments used for growth of crops under continuous artificial lighting.

White light LED with rubidium vapor emission in nested enclosure optimizing human vision and horticultural pigment irradiance

A light emitting assembly comprising at least one of each of a solid state device and a thermal radiation source, couplable with a power supply constructed and arranged to power the solid state device and the thermal radiation source, to emit from the solid state device a first, relatively shorter wavelength radiation, and to emit from the thermal radiation source non-visible infrared radiation, and a down-converting luminophoric medium arranged in receiving relationship to said first, relatively shorter wavelength radiation, and the infrared radiation, and which in exposure to said first, relatively shorter wavelength radiation, and infrared radiation, is excited to responsively emit second, relatively longer wavelength radiation. In a specific embodiment, monochromatic blue light output from a light-emitting diode is down-converted to white light by packaging the diode and the thermal radiation device with fluorescent or phosphorescent organic and/or inorganic fluorescers and phosphors in an enclosure.

A light emitting assembly comprising at least one of each of a solid state device and a thermal radiation source, couplable with a power supply constructed and arranged to power the solid state device and the thermal radiation source, to emit from the solid state device a first, relatively shorter wavelength radiation, and to emit from the thermal radiation source non-visible infrared radiation, and a down-converting luminophoric medium arranged in receiving relationship to said first, relatively shorter wavelength radiation, and the infrared radiation, and which in exposure to said first, relatively shorter wavelength radiation, and infrared radiation, is excited to responsively emit second, relatively longer wavelength radiation. In a specific embodiment, monochromatic blue or UV light output from a light-emitting diode is down-converted to white light by packaging the diode and the thermal radiation device with fluorescent or phosphorescent organic and/or inorganic fluorescers and phosphors in an enclosure.

A microelectronic device is disclosed. The microelectronic device has an outer enclosure enclosing a first gas in a first space, an inner enclosure disposed in the first space of the outer enclosure, at least one elongated elastomeric member forming the inner enclosure, and a plurality of lighting elements embedded in the at least one elongated elastomeric member.

A light emitting assembly comprising a solid state device, when and if coupleable with a power supply constructed and arranged to power the solid state device to emit from the solid state device a first wavelength radiation, and an enveloping vessel enhancing the luminescence of the solid-state device and providing a mechanism for arranging luminophoric medium in receiving relationship to said first, radiation, and which in exposure to said first radiation, is excited to responsively emit second wavelength radiation or to otherwise transfer its energy without radiation to a third radiative component. In a specific embodiment, monochromatic blue or UV light output from a light-emitting diode is converted to achromatic light without hue by packaging the diode with fluorescent organic and/or inorganic fluorescers and phosphors on the walls of the solid-state light envelope which keeps the diode and the fluorescers and phosphors under a vacuum or a rare or Noble gas.
