  • Publication number: 20170165389
    Abstract: An automated heat transfer press and method for automated heat transfer pressing provides an electric linear actuator motor that induces an arced translation of a first plate onto a second plate for dye sublimation printing. The arced motion of the first plate enables the first plate to press against the second plate at an angle, rather than a vertical pressing action; whereby adaption to a variously sized and dimensioned substrates is possible. A second link bar adjusts alignment of the second plate with first plate. An electric linear actuator motor manipulates a rod through electrical power. Rod is extended to create linear motion. The rod operatively connects to a hinged arm, applying linear force that causes the hinged arm to displace the first plate at arced motion. A control portion regulates the linear actuator motor to press and release the plates against each other in predetermined temperatures and intervals.

    Abstract: A light emitting diode chip includes an epitaxial layer with a plurality of recess portions and protrusion portions over the top layer; a light transmission layer, located between top ends of adjacent protrusion portions and forming holes with the recess portions. The light transmission layer has a horizontal dimension larger than a width of the top ends of two adjacent protrusion portions, and serves as current blocking layer; a current spreading layer covering the surface of the light transmission layer and the surface of an epitaxial layer of a non-mask light transmission layer. As the refractive index of the light transmission layer is between those of the epitaxial layer and the hole, indicating a difference of refractive index between the light transmission layer and the epitaxial layer, the probability of scattering generated when light from a luminescent layer emits upwards can be increased, thus avoiding light absorption by electrodes and improving light extraction efficiency.
