摘要： An ignition system for a high-frequency high-intensity discharge lamp system of a type used for location-lighting during filming or other entertainment venues includes a transformer with a pair of secondary windings, each having a primary winding closely interwound. The secondary windings, which are connected between the steady-state power source and the discharge lamp, are wound for producing opposing magnetic fields with substantial flux cancellation. The primary windings are wound to produce voltage amplification and connected to an ignition circuit adapted to produce high-voltage ignition spikes to turn on the discharge lamp. The system also includes a resonant circuit between the steady-state power source and the transformer. The ignition and resonant circuits are temporarily energized to produce a voltage for igniting the lamp. The advantage of secondary windings with opposing magnetic fields in that a sufficient turns ratio is present to allow the transformer to operate effectively during ignition, while at the same time the opposing magnetic fields result in a low impedance with a reduction in both heat and inductive loss during steady-state operation of the lamp system.

摘要： A method for dimming a gas discharge lamp (2), particularly a HID lamp, and more specifically a MH lamp, is described. The lamp is operated at nominal power with commutating DC current having a current magnitude IL=αInom, α being equal to 1 or less than 1. The current magnitude IL is reduced, but the lamp still is operated at commutating DC current, until a reaches a predetermined value β. Then, the lamp is operated at DC current, and the current magnitude is reduced further. It is now possible to achieve a lower dimming level.

摘要： A projector 10 of the invention measures the brightness of an image projected on a screen SC and corrects the measured brightness of the projected image with an input zoom ratio of a projection lens and an input projection distance. The projector 10 compares the corrected brightness of the projected image with a preset target value and sets a driving power of a light source lamp 52 to compensate for a difference between the normalized brightness and the preset target value. This arrangement effectively restrains potential adverse effects of a variation in luminance of illumination light emitted by the light source lamp of the projector on the brightness and the contrast of a resulting projected image.
