    摘要: A method of forming an LED lamp with a desired distribution of phosphor is disclosed. The method includes the steps of mixing a plurality of phosphor particles in an uncured polymer resin for which the viscosity can be controlled in response to temperature to form a substantially uniform suspension of the phosphor particles in the resin. The uncured resin is then placed into a defined position adjacent an LED chip and the temperature of the resin is increased to correspondingly decrease its viscosity but to less than the temperature at which the resin would cure unreasonably quickly. The phosphor particles are encouraged to settle in the lowered-viscosity resin to a desired position with respect to the LED chip, and the temperature of the resin is thereafter increased to the point at which it will cured and solidify.

    摘要: A light emitting diode is disclosed. The diode includes a package support and a semiconductor chip on the package support, with the chip including an active region that emits light in the visible portion of the spectrum. Metal contacts are in electrical communication with the chip on the package. A substantially transparent encapsulant covers the chip in the package. A phosphor in the encapsulant emits a frequency in the visible spectrum different from the frequency emitted by the chip and in response to the wavelength emitted by the chip. A display element is also disclosed that combines the light emitting diode and a planar display element. The combination includes a substantially planar display element with the light emitting diode positioned on the perimeter of the display element and with the package support directing the output of the diode substantially parallel to the plane of the display element.
