    摘要： An LED lamp or bulb is disclosed that comprises a light source, a heat sink structure and an optical cavity. The optical cavity comprises a phosphor carrier having a conversions material and arranged over an opening to the cavity. The phosphor carrier comprises a thermally conductive transparent material and is thermally coupled to the heat sink structure. An LED based light source is mounted in the optical cavity remote to the phosphor carrier with light from the light source passing through the phosphor carrier. A diffuser dome is included that is mounted over the optical cavity, with light from the optical cavity passing through the diffuser dome. The properties of the diffuser, such as geometry, scattering properties of the scattering layer, surface roughness or smoothness, and spatial distribution of the scattering layer properties may be used to control various lamp properties such as color uniformity and light intensity distribution as a function of viewing angle.

    摘要： A modular package for a light emitting device includes a leadframe having a top surface and including a central region having a bottom surface and having a first thickness between the top surface of the leadframe and the bottom surface of the central region. The leadframe may further include an electrical lead extending away from the central region. The electrical lead has a bottom surface and has a second thickness from the top surface of the leadframe to the bottom surface of the electrical lead. The second thickness may be less than the first thickness. The package further includes a package body on the leadframe surrounding the central region and exposing the bottom surface of the central region. The package body may be at least partially provided beneath the bottom surface of the lead and adjacent the bottom surface of the central region. Methods of forming modular packages and leadframes are also disclosed.

    摘要： Methods and systems for coating of semiconductor devices using droplets of wavelength conversion or phosphor particles in a liquid medium. A plurality of nozzles delivers a controlled amount of the matrix material to the surface of the semiconductor device, with each of said nozzles having an opening for the matrix material to pass. The opening has a diameter wherein the diameter of the phosphor particles is less than or approximately equal to one half the diameter of the opening. The phosphor particles are also substantially spherical or rounded. The nozzles are typically arranged on a print head that utilizes jet printing techniques to cover the semiconductor device with a layer of the matrix material. The methods and systems are particularly applicable to covering LEDs with a layer of phosphor materials.

    摘要： An emitter package comprising a light emitting diode (LED) emitting light at a wavelength within a wavelength range and a plurality of phosphors. Each of the phosphors absorbs at least some light from the LED and re-emits a different wavelength of light. The package emits a combination of light from the LED and the plurality of phosphors, with the phosphors having excitation characteristics such that the emitter package emits light within a standard deviation of a target color for LEDs emitting at the wavelengths with the wavelength range. A method for fabricating emitter packages comprising fabricating a plurality of LEDs, each of which emits at a wavelength within a range of wavelengths. Each of the LEDs are arranged in a respective package with a plurality of conversion materials so that at least some light from each of the LEDs is absorbed and re-emitted by its corresponding conversion materials. The plurality of conversion materials have excitation characteristics that compensate for different LED emission wavelengths within the LED range of wavelengths such that each of the LED packages emits light within a standard deviation from a target color.
