  • Publication number: 20210127466
    Abstract: A lighting device capable of generating warm or neutral white light using blue light-emitting diodes (“LEDs”), red LEDs, and/or luminescent material that responds to blue LED emission is disclosed. The lighting device includes multiple first solid-state light-emitting structures (“SLSs”), second SLSs, and balancing resistor element. The first SLS such as a string of blue LED dies connected in series is able to convert electrical energy to blue optical light, which is partially turned into longer wavelength emission by the luminescent material. The second SLS such as a red LED die is configured to convert electrical energy to red optical light, wherein the second SLSs are connected in series. While the first SLSs and second SLSs are coupled in parallel, the balancing resistor element provides load balance for current redistribution between the first and second SLSs in response to fluctuation of operating temperature.

  • Patent number: 10665762
    Abstract: LED lamps or bulbs are disclosed that comprise 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. The phosphor carrier can have a three-dimensional shape and comprise a thermally conductive transparent material and a phosphor layer, with an LED based light source mounted to the heat sink such that light passes through the phosphor carrier. The phosphor carrier converts at least some of the LED light, with some embodiments emitting a white light combination of LED and phosphor light. The phosphors in the phosphor carriers can operate at a lower temperature to have greater phosphor conversion efficiency and reduced heat related damage. The lamps or bulbs can also comprise a diffuser over the phosphor carrier to distribute light and conceal the phosphor carrier.

  • Publication number: 20190371770
    Abstract: Light emitting assemblies comprise a plurality of Light Emitting Diode (LED) dies arranged and attached to common substrate to form an LED array having a desired optimum packing density. The LED dies are wired to one another and are attached to landing pads on the substrate for receiving power from an external electrical source via an interconnect device. The assembly comprises a lens structure, wherein each LED die comprises an optical lens disposed thereover that is configured to promote optimal light transmission. Each optical lens has a diameter that is between about 1.5 to 3 times the size of a respective LED die, and is shaped in the form of a hemisphere. Fillet segments are integral with and interposed between the adjacent optical lenses, and provide sufficient space between adjacent optical lenses so that the diameters of adjacent optical lenses do not intersect with one another.

  • Patent number: 10359151
    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.

  • Patent number: 10347806
    Abstract: A packaged UV-LED device comprises a die carrier member having a cup-shaped recess, a fused silica lens member that is anodic bonded to the die carrier member, and a UV-LED die that is flip-chip mounted within a sealed cavity formed by the carrier member and the lens member. The carrier member involves a unitary cup member fashioned in an economical way from monocrystalline silicon wafer material. A dielectric/aluminum reflector that is effective for UV radiation and that does not degrade and overheat is disposed on the sidewalls of the recess. The lens member is anodic bonded to a silicon surface of the rim of this unitary cup member at a time when the UV-LED die is disposed in the recess. The anodic bonding is done in such way that the die is not damaged and such that the entire packaged UV-LED device includes no UV-degradable adhesive.

  • Patent number: 10325890
    Abstract: Standardized photon building blocks are packaged in molded interconnect structures to form a variety of LED array products. No electrical conductors pass between the top and bottom surfaces of the substrate upon which LED dies are mounted. Microdots of highly reflective material are jetted onto the top surface. Landing pads on the top surface of the substrate are attached to contact pads disposed on the underside of a lip of the interconnect structure. In a solder reflow process, the photon building blocks self-align within the interconnect structure. Conductors in the interconnect structure are electrically coupled to the LED dies in the photon building blocks through the contact pads and landing pads. Compression molding is used to form lenses over the LED dies and leaves a flash layer of silicone covering the landing pads. The flash layer laterally above the landing pads is removed by blasting particles at the flash layer.
