  • Patent number: 10165632
    Abstract: A light-emitting diode driving module includes an LED driving circuit to activate light-emitting diodes driven by a rectified voltage, and to adjust driving current conducted through driving nodes to the light-emitting diodes depending on a voltage of a driving current setting node; and a driving current controller to control the voltage of the driving current setting node by outputting a driving current control signal. The driving current controller includes a control signal output circuit connected to a dimming node to receive a dimming signal when the rectified voltage is modulated, and to adjust the driving current control signal depending on the dimming signal; a mode detector to detect whether the rectified voltage is modulated by receiving a source voltage depending on the rectified voltage, and to enable a selection signal depending on a detection result; and a power compensator to adjust the driving current control signal when the selection signal is enabled.

  • Publication number: 20180297321
    Abstract: Devices, systems and techniques are described for producing and implementing articles and materials having nanoscale and microscale structures that exhibit superhydrophobic, superoleophobic or omniphobic surface properties and other enhanced properties. In one aspect, a surface nanostructure can be formed by adding a silicon-containing buffer layer such as silicon, silicon oxide or silicon nitride layer, followed by metal film deposition and heating to convert the metal film into balled-up, discrete islands to form an etch mask. The buffer layer can be etched using the etch mask to create an array of pillar structures underneath the etch mask, in which the pillar structures have a shape that includes cylinders, negatively tapered rods, or cones and are vertically aligned. In another aspect, a method of fabricating microscale or nanoscale polymer or metal structures on a substrate is made by photolithography and/or nano imprinting lithography.
