Phosphor-centric control of color of light

Автор: David P. Ramer, Jack C. Rains, Jr.

Lighting devices and/or systems offer dynamic control or tuning of color of light. The lighting systems utilize sources, such as solid state sources, to individually pump a number of different phosphors of types having relatively high degrees of color purity. The phosphor emissions, however, are still broader than the traditionally monochromatic color emissions of LEDs. The different phosphors can be independently excited to controllable levels, by individually controlled sources rated for emission of energy of the same spectrum. Adjustment of intensities of electromagnetic energy emitted by the sources independently adjusts levels of excitations of the phosphors selected to emit different colors of relatively high purity and thus the contributions of pure colors to the combined light output, for example, to enables color adjustment of the light output over a wide range of different selectable colors encompassing much of the gamut of visible light.

The heat sink includes a heat collecting section and a holding section extended from the heat collecting section into the power receiving base such that the power receiving base fully encases the heat sink without exposing. The inner surface of the power receiving base connects to the outer surface of the holding section so that heat generated by the light source baseboard is absorbed by the heat collecting section and transmitted via the holding section to the power receiving base for dissipating.

Принадлежит: Individual

A lamp ( 1 ) has one or more LED's ( 2 ), supported above an open structure ( 7 ). The lamp ( 1 ) is made from thermoplastic material and has a base ( 3 ) including threads ( 4 ) and a lower contact ( 5 ). A thermoplastic body ( 6 ) of larger diameter is located above the base and has an open structure portion ( 7 ) preferably shaped as a truncated inverted and open cone. An upper part of the cone supports a circuit board ( 8 ) with a laminar form that supports the light emitting diodes ( 2 ). A upper semispherical element ( 9 ) is located over the body ( 6 ) and forms a light diffuser. An upper center of the base ( 3 ) has an internal electronic circuit ( 10 ) for connecting to a power source. The LED lamp with the open structure eases installation, has lower weight and cost, allows easy recycling and provides greater security for users.
