  • Patent number: 11500243
    Abstract: The present disclosure provides an LED assembly, a light source, and a liquid crystal display device. The LED assembly includes: a substrate; a plurality of blue LED chips which are disposed on the substrate at intervals and have different emission wavelengths; a white light phosphor layer which is disposed on the substrate and covers the plurality of blue LED chips; and a sealing frame which is disposed on the substrate and is configured to encapsulate the plurality of blue LED chips and the white light phosphor layer. The LED assembly encapsulates the blue LED chips having different emission wavelengths together, which can avoid LED mixing from an LED encapsulation source, thereby saving cost. Moreover, problems such as nonuniform images and chromatic aberration are basically avoided when the LED assembly is applied to an LCD module.

  • Patent number: 10824065
    Abstract: This light source apparatus includes a wheel, a motor, a rotation member, and a contact member. The wheel includes a light emitter that is excited by excitation light and emits visible light, and a base that includes a first surface and a second surface opposite thereto, supports the light emitter on either one of the first and second surfaces, and has a first linear expansion coefficient. The motor generates rotational force for rotating the base. The rotation member is connected to the first surface of the base, rotates integrally with the base due to the rotational force of the motor, and has a second linear expansion coefficient different from the first linear expansion coefficient. The contact member is connected to the second surface of the base and has a third linear expansion coefficient whose magnitude relationship to the first linear expansion coefficient is equal to a magnitude relationship of the second linear expansion coefficient to the first linear expansion coefficient.

  • Patent number: 10627079
    Abstract: A special effects apparatus for generating an illusion of a moving beam of light in midair. The apparatus includes a light source, such as a laser light source outputting colored light, generating a beam of light that is aimed along a linear light travel path. The apparatus further includes a dynamic light receiving assembly, and this assembly includes: an elongated support rod; a light receiving element attached to a first end of the support rod; and a driver coupled to a second end of the support rod opposite the first end of the support rod. The driver rotates the support rod about the second end at a high rotation rate, and the light receiving element moves along an arcuate travel path that intersects the linear light travel path of the beam of light. The arcuate travel path of the light receiving element and the linear light travel path are coplanar.

  • Patent number: 10619561
    Abstract: A centrifugal compressor for a turbocharger includes an inlet-adjustment mechanism operable to move between an open position and a closed position. The inlet-adjustment mechanism includes a plurality of blades disposed about the compressor air inlet and located between an upstream wall surface and a downstream wall surface of an annular space within the air inlet wall. The blades are pivotable about respective pivot points such that the blades extend radially inward from the annular space into the air inlet when the blades are in the closed position so as to form an orifice of reduced diameter relative to a nominal diameter of the inlet. Aerodynamic pressure balancing across the blades is achieved by spacing features that space a majority of the upstream surface of each blade from the opposing upstream wall surface.
