Abstract: The light stand includes a frame having a offset base with upper and lower legs that to allow for the nesting of adjacent light stands for more compact transport and storage. The light stand includes a dual-mast design with a top beam that allows a light fixture to be connected thereto. So that the light stand can be readily used in inclement weather and to protected the light fixture from knocking damage if it were to fall over or be accidently hit, the preferred embodiment of the light fixture includes a socket assembly with a flange having an elongated sidewall such that the fastening portion of the bulb extends into the flange of the socket and is protected from the elements. The light stand also includes an outlet to provide power to other lights or items used therewith.

Abstract: The disclosure relates in general to privacy glass, and more particularly, to a privacy glass system containing a light source, a diffuser, and a control and power circuitry combined in such a fashion as to make the level of visibility through the privacy glass system controllable.

Abstract: A method and circuit to use light-emitting diodes to emulate the dimming performance of incandescent lighting, and more particularly, to making a circuit that uses only white and deep red light-emitting diodes to achieve a coordinated-color-temperature as a function of dim level that is close to that of an incandescent light being similarly dimmed.

Abstract: A universal AC-line input light emitting diode (LED) drive that automatically transitions to the most favorable configuration of the LEDs based on the particular range of line voltage input applied.

Abstract: A universal AC-line input light emitting diode (LED) drive includes a rectifier, at least one LED connected to one output of the rectifier, a controllable element in series with the at least one LED, and a circuit for turning off the controllable element when the line voltage exceeds a reference voltage. The reference voltage is selected to produce the average current through the LEDs when the line voltage is nominally 120VAC, 240VAC, or 277VAC. Another circuit may also be provided for switching the reference voltage between at least two levels (e.g., two of 120VAC, 240VAC, or 277VAC) when an average line voltage exceeds a certain level.
