Abstract:
An image display device includes a light source; a power supply section that supplies power to light source; a cooling fan that cools the light source; an input section; a drive section that supplies a voltage to cooling fan; a control section that controls drive section and power supply section. The control section sets a first power value for the output of the power supply section and also a first voltage value for the output of the drive section. The control section measures a time at which the light source has been lighted. If the measured value exceeds a threshold, the control section gradually increases the output of the power supply section up to a second power value that is greater than the first voltage value over a predetermined time.
Abstract:
The excitation source consists of at least three identical electrodes arranged symmetrically in relation to the axis of the central tube, which supplies an analytical sample, and electrode cooling agent supply and removal systems. The electrodes are mounted in an electrically isolated metal housing so that the electrode tops are placed at the central tube outlet, and their ends are shorted in the power supply point with the microwave connections embedded in the housing on the extension of the electrode longitudinal axis and the connections are coupled with the microwave power source, the length of each electrode is ¼ L, where L is the length of the microwave. Each electrode has a hollowed longitudinal flow chamber for the cooling agent connected with metal side tubes, which supply and remove the cooling agent, while outside tube ends are electrically shorted with the housing.
Abstract:
A solid state lighting apparatus can include a substrate having first and second opposing surfaces, where at least one of the opposing surfaces is configured to mount devices thereon. A string of chip-on-board light emitting diode (LED) sets, can be on the first surface of the substrate and coupled in series with one another. An ac voltage source input, from outside the solid state lighting apparatus, can be coupled to the first or second surface of the substrate.
Abstract:
A microwave-excited ultraviolet lamp system includes a microwave chamber cooled with air drawn through the chamber by a negative pressure source. A filter provided at an inlet of the lamp system prevents particulate material from entering the microwave chamber.
Abstract:
A lamp assembly includes a reflector body having an integral crimping portion that extends inwardly over a channel formed in the reflector body, a seal feature arranged within the channel, a cathode assembly having an edge feature extending into the channel, and a resilient member held in a state of compression between the crimping portion and a first surface of the edge feature such that an opposing second surface of the edge member is held against the sealing feature thereby creating a hermetic seal between the cathode assembly and the reflector body wherein the crimping portion is configured to remain in contact with the resilient member if the hermetic seal becomes non-hermetic.
