  • Publication number: 20140184127
    Abstract: The present disclosure is directed to a solution that provides for continuous adjustment of a reference signal to a control chip to facilitate controlling the average output power. In some aspects, a system may facilitate continuous adjustment of power provided to a device by providing a reference signal with a slope to a control pin (e.g., current control pin) of a control chip (e.g., power regulator or LED driver). Providing a reference signal with a slope (e.g., a triangle or a sinusoidal wave) can increase the control range of the control chip and improve control chip performance. For example, systems and methods of the present disclosure may increase the dimming range of an LED from less than 0.1% to 100%.

  • Publication number: 20090195189
    Abstract: A lighting arrangement includes a light fixture including a plurality of light sources wherein each light source is configured to generate a different color light when energized; and a circuit arrangement included in the light fixture and operatively interposed between the plurality of light sources and a source of electrical power. This circuit arrangement is responsive to brief interruptions in the supply of electrical power of less than a predetermined period to simultaneously de-energize all of the light sources for a full duration of the interruption and to subsequently toggle energization from one light source to the next and thereby produce different color light in response to the cessation of the brief interruption.
