  • Publication number: 20110303946
    Abstract: A phase change material (PCM) is used as thermal storage for lighting systems. The PCM is placed in a thermally conductive container in close contact with the lighting system. As the PCM absorbs heat, it changes from a solid to a liquid state, but the temperature of the PCM is clamped at its melting point temperature. For LED-based systems, the PCM is selected to have a melting point such that the junction temperatures of the LEDs in the system are maintained at approximately their optimum operating temperature inside the lighting system housing. Because the thermal conductivity of the molten PCM is poor, a low thermal resistance heat flow path is provided from the PCM to the container.

  • Publication number: 20110215345
    Abstract: Lamps and bulbs are disclosed generally comprising different combinations and arrangements of a light source, one or more wavelength conversion materials, regions or layers which are positioned separately or remotely with respect to the light source, and a separate diffusing layer. This arrangement allows for the fabrication of lamps and bulbs that are efficient, reliable and cost effective and can provide an essentially omni-directional emission pattern, even with a light source comprised of a co-planar arrangement of LEDs. The lamps according to the present invention can also comprise thermal management features that provide for efficient dissipation of heat from the LEDs, which in turn allows the LEDs to operate at lower temperatures. The lamps can also comprise optical elements to help change the emission pattern from the generally directional (e.g. Lambertian) pattern of the LEDs to a more omni-directional pattern.
