  • Variable hue task lamp with novel hue selection component
    Patent number: 11212888
    Abstract: A variable hue task lamp with novel hue selection component is disclosed herein. The color and intensity of a task lamp is adjusted using a wireless connection from a device such as a smart phone, tablet, or computing device based upon an optimization method using a sample text or scene. The user first optimizes hue by adjusting the background color of the sample text or picture on the device. The optimum hue is then communicated to the task light, which sets light emitting diode intensities to match the optimum choice. Presets further localize choices in color space, and a comparison to white verifies the benefits of the chosen hue.
