摘要： A discharge lamp lighting device includes: a power converting circuit including a step-down chopper circuit (1) and a polarity inversion circuit (2) configured to convert an output from the step-down chopper circuit (1) to a rectangular-wave alternating-current voltage, and thus to apply the rectangular-wave alternating-current voltage to a discharge lamp (La); and a memory (41f) configured to store a history of an output from the power converting circuit in a previous stable lighting mode. A control circuit (4) controls the on and off of each of switching elements (Q1 to Q5) in the step-down chopper circuit (1) and the polarity inversion circuit (2), and thereby changes the output from the power converting circuit in a predetermined time period after the lamp starts lighting until reaching a stable lighting state on the basis of the history stored in the memory (41f), so that a rise of a lamp voltage Vla is suppressed. This enables extension of the lifespan of the lamp and suppression of the occurrence of arc jump.

摘要： A light emitting module device includes: a power line through which power is supplied to light emitting modules; and a signal generation circuit which generates a control signal. The power line is shared by a plurality of the light emitting modules, and has switches and switches which turn on or off current conduction to the light emitting modules, through open/close operations. The signal generation circuit individually controls the switches and the switches. The open/close operations include a light-emission period in which the light emitting module emits light; and an extinction period in which the light emitting module is extinguished, and if there is a control signal to be transmitted to the light emitting module, the control signal is superimposed onto supply power. Since a control signal is superimposed onto supply power to each light emitting module, the light emitting modules can be individually controlled. In addition, since the power line can be used also as a communication line, and the power line can be shared by a plurality of the light emitting modules, the number of lines can be decreased.
