    摘要： One close loop system and method for electrophoretic deposition (EPD) of phosphor material on light emitting diodes (LEDs). The system comprises a deposition chamber sealed from ambient air. A mixture of phosphor material and solution is provided to the chamber with the mixture also being sealed from ambient air. A carrier holds a batch of LEDs in the chamber with the mixture contacting the areas of the LEDs for phosphor deposition. A voltage supply applies a voltage to the LEDs and the mixture to cause the phosphor material to deposit on the LEDs at the mixture contacting areas.

    摘要： An LED lamp or bulb is disclosed that comprises a light source, a heat sink structure and a remote phosphor carrier having at least one conversion material. The phosphor carrier can be remote to the light sources and mounted to the heat sink so that heat from the phosphor carrier spreads into the heat sink. The phosphor carrier can have a three-dimensional shape, and can comprise a thermally conductive transparent material and a phosphor layer, with an LED based light source mounted to the heat sink such that light from the light source passes through the phosphor carrier. At least some of the LED light is converted by the phosphor carrier, with some lamp embodiments emitting a white light combination of LED and phosphor light. The phosphors in the phosphor carriers can be arranged to operate at a lower temperature to thereby operate at greater phosphor conversion efficiency and with reduced heat related damage to the phosphor. The lamps or bulbs can also comprise a diffuser over the phosphor carrier to distribute light and to conceal the phosphor carrier.

    摘要： 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.

    摘要： Lamps and bulbs are disclosed generally comprising different combinations and arrangement 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. Additionally, this arrangement allows aesthetic masking or concealment of the appearance of the conversion regions or layers when the lamp is not illuminated. Some embodiments of the present invention utilize LED chips to provide one or more lighting components instead of providing the components through phosphor conversion. This can provide for lamps that can be operated with lower power and can be manufactured at lower cost. In one embodiment, a red lighting component can be provided by red emitting LEDs as opposed to a red conversion material.
