Title: Innovations of Samuel Maurice Berman
Introduction
Samuel Maurice Berman is a notable inventor based in San Francisco, CA. He holds a total of 6 patents that reflect his contributions to the field of lighting technology. His work focuses on enhancing circadian lighting systems and developing high-intensity discharge lamps.
Latest Patents
One of Berman's latest patents is an "Apparatus, method, and system for providing tunable circadian lighting at constant perceived brightness and color." This invention utilizes the newly discovered retinal ganglion cell photoreceptor melanopsin, which is absent in the central fovea of the eye but is distributed throughout the remaining human retinal body. The invention aims to improve circadian lighting systems by allowing ambient and device background lighting to be temporally tuned over a range of prescribed color temperatures. This tuning is designed to maintain a constant perceived brightness and color throughout the temporal adjustments.
Another significant patent is the "RF driven sulfur lamp having driving electrodes which face each other." This high-intensity discharge lamp operates without mercury and radiates a selected spectrum that is predominantly in the visible range. The lamp employs a signal source to generate an excitation signal that is coupled to the exterior surface of the envelope containing a sulfur-containing substance. Various embodiments of the lamp are designed to minimize filamentary discharges and optimize the emitted spectrum.
