摘要： An excimer bulb assembly including an excimer bulb emitting a beam of UV light at a wavelength of 222 nm. The excimer bulb may include a filter that blocks any unwanted wavelengths of UV light. The assembly includes a focusing lens positioned a distance from the excimer bulb such that the emitted beam of UV light strikes the focusing lens at an angle. The distance between the excimer bulb and the focusing lens may be varied such that the angle changes when the distance is varied. A plurality of excimer bulbs emitting a beam of UV light at a wavelength of 222 nm in a pattern may be including in a fixture. The fixture may include a housing with the plurality of excimer bulbs are secured in the housing. At least one of the plurality of excimer bulbs may be adapted to independently swivel with respect to the housing so as to change the pattern of the emitted beam of UV light. Each of the plurality of excimer bulbs may be adapted to independently tilt with respect to the housing.

摘要： A dynamically optimized ballast includes a ballast and a circuit board as main components combined together. Said circuit board is provided with a microcontroller, a timer and a current-switching device; wherein said microcontroller is provided with a timed step-up module which can start the timer and maintain a low current output to HID lamp at the time the circuit board is powered, and the timer will transmit a signal to the microcontroller to start the current-switching device and automatically switch to a high current output to HID lamp when a preset time of the timer has been reached. So that this invention can protect HID lamp and extend the service life of HID lamp, even the HID lamp pulsing for a long time, the power source repeated power supply and power out will not cause great damage to HID lamp and it will not be out of function. Besides, this invention enables user to reduce the brightness of HID lamp to reduce the loss of electric power and the deterioration of HID lamp.

摘要： The current subject matter relates to a lighting device that can be installed in an already existing fixture in a structure. The lighting device can include a light emitting diode (LED) lighting segment and a fluorescent lighting segment. The LED lighting segment can include a LED lighting source, and the fluorescent lighting segment can include a fluorescent lighting source. The LED lighting source can be activated. Motion sensors and/or occupancy sensors can detect motion and/or occupancy of an occupant in the structure. If there is motion or if the occupancy is more than a predetermined threshold, the fluorescent lighting source can be activated. After each regular interval of time, the detection of motion or occupancy can be re-performed. If there is no detection of motion and/or occupancy, the fluorescent lighting source can be deactivated, after a period of time. Related apparatus, systems, techniques and articles are also described.

摘要： An electronic dimming ballast or light emitting diode (LED) driver for driving a gas discharge lamp or LED lamp may be operable to control the lamp to avoid flickering and flashing of the lamp during low temperature or low mercury conditions. Such a ballast or driver may include a control circuit that is operable to adjust the intensity of the lamp. Adjusting the intensity of the lamp may include decreasing the intensity of the lamp. The control circuit may be operable to stop adjustment of the intensity of the lamp if a magnitude of the lamp voltage across the lamp is greater than an upper threshold, and subsequently begin to adjust the intensity of the lamp when the lamp voltage across the lamp is less than a lower threshold. Subsequently beginning to adjust the intensity of the lamp may include subsequently decreasing the intensity of the lamp.
