A system includes at least one lighting device, e.g., at least one LED luminaire, and a control circuit configured to control a spectral output produced by the at least one lighting device responsive to environmental information about an area illuminated by the at least one lighting device. The control circuit may be configured to control a color temperature of the illumination responsive to the environmental information. In some embodiments, the control circuit may be configured to lower the color temperature of the illumination responsive to the environmental information indicating a level of reflected light and/or a weather condition, such as precipitation, correlated with the presence or likely presence of glare.

Glare-reactive lighting apparatus

A LED lamp has a base and an at least partially optically transmissive enclosure connected to the base. A heat sink is partially disposed in the enclosure and supports a plurality of LEDs. The heat sink comprising a mounting portion positioned in the enclosure for supporting the LEDs and a heat dissipating portion exposed to the ambient environment where the interior of the enclosure is exposed to the ambient environment. The heat sink have a plurality of separate heat sink structures that are mounted to the lamp independently of one another. Each heat sink structure may have a thickness of approximately 1-5 mm. Each heat sink structure may in some embodiments weigh approximately 3.8 to 7.7 grams and in other embodiments weigh approximately 27 grams.

LED lamp

An LED lighting system includes an LED assembly for emitting light when energized through an electrical path. An optic element in the enclosure receives the light emitted by the LED assembly and disperses the light from the enclosure. The optic element comprises a light guide for transmitting light from the LED assembly to a light emitting portion where the light emitting portion is configured to visually appear like a filament in a traditional bulb.

LED based lighting system

An LED based lamp has an optically transmissive enclosure connected to a base. The base may include a heat sink. A substrate is positioned in the enclosure and supports a plurality of LEDs where the periphery of the substrate has alternating recessed portions and protruding portions that define a plurality of laterally extending projections. One LED is located on each of the projections to increase the amount of down light generated by the lamp.
