Abstract: Solid state light emitting devices include multiple LED components providing adjustable melatonin suppression effects. Multiple LED components may be operated simultaneously according to different operating modes according to which their combined output provides the same or similar chromaticity, but provides melatonin suppressing effects that differ by at least a predetermined threshold amount between the different operating modes. Switching between operating modes may be triggered by user input elements, timers/clocks, or sensors (e.g., photosensors). Chromaticity of combined output of multiple LED components may also be adjusted, together with providing adjustable melatonin suppression effects at each selected combined output chromaticity.

Abstract: Solid state light sources, lighting devices and lamps arranged to provide emission with a warm temperature and high CRI. One embodiment of a solid state lighting device according to the present invention comprises a light emitting diode (LED) device capable of emitting light in an emission spectrum. A filter arranged so that at least some light from the LED light source passes through it, with the filter filtering at least some of one or more portions of the light source emission spectrum. The resulting light source light has a different temperature but substantially the same CRI after passing through the filter.

Abstract: A lamp has an optically transmissive enclosure and a base. A tower extends from the base into the enclosure and supports an LED assembly in the enclosure. The LED assembly comprises a plurality of LEDs operable to emit light when energized through an electrical path from the base. The tower and the LED assembly are arranged such that the plurality of LEDs are disposed about the periphery of the tower in a band and face outwardly toward the enclosure to create a source of the light that appears as a glowing filament. The tower forms part of a heat sink that transmits heat from the LED assembly to the ambient environment. The LED assembly has a three-dimensional shape. An electrical interconnect connects a conductor to the heat sink where the conductor is in the electrical path between the LED assembly and the base.
