摘要： A high watt type ceramic metal halide lamp illumination device is provided. The device comprises: ballast receiving a primary input voltage and outputting a secondary voltage, and a lamp having a plurality of arc tubes electrically connected in series inside an outer bulb. The lamp is lighted by receiving the secondary voltage output from the ballast. The secondary voltage output from the ballast has a waveform that at least satisfies a maximum-value to effective-value ratio (Vmax/Veff) of greater than 20.5. When using two 360 W arc tubes of a popular type by electrically connecting the two in series instead of a 700 W arc tube of a high-watt type, for example, it is preferable to use a triangular waveform AC voltage that satisfies 260≦Veff(triangular waveform) when expressed by the effective-value, and 500 V≦Vmax(triangular waveform) when expressed by the maximum-value.

摘要： A high pressure discharge lamp ballast performs driving with a synthesized current waveform comprising a combination of first and second sets of current waveforms. The ballast controls content rates of each of the sets per unit time; detects a rotation synchronization signal for a color wheel; applies a synthesized current waveform in accordance with the synchronization signal and the content rates to a high pressure discharge lamp; and detects a lamp voltage. A period of each of the first and second sets equals to one rotation of the color wheel. The number of inversions of the second set is larger than that of the first set. The content rate of the second set is set to RL% when the lamp voltage exceeds a value V, and the content rate of the second set is set to RH% when lamp voltage falls below a value V′.

摘要： The high pressure discharge lamp ballast drives a high pressure discharge lamp with a synthesized-waveform alternating current made of multiple frequency components, the high pressure discharge lamp having a pair of electrodes disposed to face each other. The ballast controls a ratio of the multiple frequency components per unit time; applies a synthesized-waveform current in accordance with the ratio to the high pressure discharge lamp; and detects a lamp parameter of the high pressure discharge lamp. The control circuit is configured to shift the ratio to a first ratio when the lamp parameter is in a first state, and shifts the ratio to a second ratio when the lamp parameter is in a second state. The control circuit changes the ratio stepwise when the ratio is shifted from the first ratio to the second ratio, or when the ratio is shifted from the second ratio to the first ratio.

摘要： Even when usable driving frequencies are limited, a lamp voltage is appropriately controlled. A high pressure discharge lamp ballast performs driving with a synthesized current waveform comprising a combination of first and second sets of current waveforms. The ballast includes: a control means for controlling content rates of each of the sets per unit time; a detection means for detecting a rotation synchronization signal for a color wheel; an output means for applying a synthesized current waveform in accordance with the synchronization signal and the content rates to a high pressure discharge lamp; and a detection means for detecting a lamp voltage. The sets are each in a waveform inverted so as to correspond to at least one of a rotational speed and segment positions of color wheel. A period of each of the first and second sets has a length equivalent to one rotation of the color wheel. The number of inversions of the second set is larger than the number of inversions of the first set. The ballast is configured in that the content rate of the second set is set to RL % when the lamp voltage exceeds a predetermined value V, and the content rate of the second set is set to RH % (0=RL
