  • Light source module
    Patent number: 10067383
    Abstract: A light source module including a substrate, a plurality of light source, and a first three-dimensional optical control structure is provided. The substrate includes a periphery region and a middle region. The plurality of light sources is disposed on the substrate. The first three-dimensional optical control structure is located in the periphery region of the substrate and located above the plurality of light sources. The first three-dimensional optical control structure covers one of the plurality of light sources. The light generated by the light sources passes through the first three-dimensional optical control structure and is emitted out. The first three-dimensional optical control structure has an asymmetrical shape.

  • Oscillating signal generator, phase-lock loop circuit using the oscillating signal generator and control method of the oscillating signal generator
    Patent number: 9374099
    Abstract: An oscillating signal generator includes: a controllable oscillator arranged to output an oscillating signal according to a control signal and a band adjusting signal; a control circuit arranged to generate a continuous signal having a specific slew-rate when the control signal reaches a boundary of a control signal interval; and a current mirror arranged to generate the band adjusting signal according to at least the continuous signal.
