Abstract: The frequency of the alternating current to be supplied to the high-pressure discharge lamp is switched among a first frequency, a second frequency greater than the first frequency, and a third frequency smaller than or equal to the first frequency. In the switching, a period A, in which the alternating current of the third frequency is supplied, occurs at the beginning of each of the predetermined time intervals. A remainder of each of the predetermined time intervals includes a period B, in which the alternating current of the first frequency is supplied, and a period C, in which the alternating current of the second frequency is supplied, the periods B and C being alternately repeated, so as to control the period A to be longer than the period B and to have a length corresponding to a predetermined number of cycles, ranging from 5.5 to 50 cycles inclusive.

Abstract: A triggerable ceramic gas tube voltage breakdown device, particularly adapted for use in an electrical circuit for controlling the light output of a photoflash lamp, includes means for reducing the attenuation of an electrical trigger pulse in the region of the electrode gap due to the ceramic spacer tube. The electric field intensity in the region of the electrode gap resulting from the trigger pulse may be enhanced by disposing annular conductive material in the region and by connecting that material to a source of the trigger pulses. Alternatively or in conjunction therewith, the configuration of the ceramic spacer tube may be altered by removing material from the ceramic spacer tube in the region of the electrode gap, thereby enhancing the electric field intensity in that region resulting from the trigger pulses.

Abstract: A light-emitting diode (LED)-based solid-state device comprises a color mixing mechanism to dynamically change the correlated color temperature (CCT) of a white light. With different lumen proportions for white phosphor-coated LEDs and integrated red and green LEDs, the light mixtures can be located in any one of eight CCT quadrangles. In practice, CCTs of a white-light can be tuned in a continuous manner. Because all the possible light mixtures on the chromaticity diagram correspond to a line segment that overlays the Planckian locus within the eight CCT tolerance quadrangles, the effect of LED intensity fluctuations that may put the mixture out of white light region is reduced. Also, because the two additional LEDs that mix with the white phosphor-coated LEDs contribute to the overall spectral power distribution (SPD) that substantially matches the SPD of standard illuminants, a CRI of 80 can be reached.
