摘要： Solid state lamps and bulbs 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 diffuser. These are arranged on a heat sink in a manner that 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. Various embodiments of the invention may be used to address many of the difficulties associated with utilizing efficient solid state light sources such as LEDs in the fabrication of lamps or bulbs suitable for direct replacement of traditional incandescent bulbs. Embodiments of the invention can be arranged to fit recognized standard size profiles such as those ascribed to commonly used lamps such as incandescent light bulbs, while still providing emission patterns that comply with ENERGY STAR® standards.

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： A light emitting diode (LED) grown on a substrate doped with one or more rare earth or transition elements. The dopant ions absorb some or all of the light from the LED's active layer, pumping the dopant ion electrons to a higher energy state. The electrons are naturally drawn to their equilibrium state and they emit light at a wavelength that depends on the type of dopant ion. The invention is particularly applicable to nitride based LEDs emitting UV light and grown on a sapphire substrate doped with chromium. The chromium ions absorb the UV light, exciting the electrons on ions to a higher energy state. When they return to their equilibrium state they emit red light and some of the red light will emit from the LED's surface. The LED can also have active layers that emit green, blue and UV light, such that the LED emits green, blue, red and UV light which combines to create white light. Alternatively, it can have one active layer and grown on a sapphire substrate doped with Cr, Ti, and Co such that the substrate absorbs the UV light and emits blue, green, and red light. The invention is also capable of providing a tunable LED over a variety of color shades. The invention is also applicable to solid state lasers having one or more active layers emitting UV light with the laser grown on a sapphire substrate doped with one or more rare earth of transition elements.

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.

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： A light emitter package having increased feature sizes for improved luminous flux and efficacy. An emitter chip is disposed on a submount with a lens that covers the emitter chip. In some cases, the ratio of the width of the light emitter chip to the width of said lens in a given direction is 0.5 or greater. Increased feature sizes allow the package to emit light more efficiently. Some packages include submounts having dimensions greater than 3.5 mm square used in conjunction with larger emitter chips. Materials having higher thermal conductivities are used to fabricate the submounts, providing the package with better thermal management.
