An illumination load determination device includes an illumination load; a voltage applying unit for applying a voltage to the illumination load; a connection unit for connecting the illumination load and the voltage applying unit; a detection unit for detecting at least one of a current flowing through the illumination load and a voltage across the illumination load when the voltage is applied to the illumination load from the voltage applying unit via the connection unit; and a determination unit for determining a type of the illumination load based on an output from the detection unit. The determination unit has a comparator for comparing a detection value detected by the detection unit to a predetermined threshold, and determines that the illumination load has a capacitance based on an output of the comparator. The voltage applying unit lights on the determined illumination load with a rated driving voltage.

An object of the present invention is directed to a method for assaying the severity of an illness in real time and is to provide a testing method capable of assessing the severity of an illness in more detail than the conventional APACHE II and SOFA scores. The established method can accurately measure an ATP level in a sample, thereby accurately and quickly deducing the “state of intracellular energy required for living organisms” from the ATP level, and by extension, determining the severity of an illness. The present invention further provides a novel biomarker ATP-lactate energy risk score (A-LES) value that is capable of determining the severity of an illness by the reevaluation, with the ATP concentration as an index (specifically, on the basis of a lactic acid level (mM)/ATP concentration (mM) ratio), of the level of lactic acid that accumulates in the sample due to the breakdown of in vivo metabolic balance accompanied by the increased severity of the illness. The present invention also provides a novel biomarker ATP-ketone energy risk score (A-KES) value that is capable of determining the severity of an illness by the reevaluation of a ketone body level in the sample with the ATP concentration as an index (specifically, on the basis of a ketone body level (mM)/ATP concentration (mM) ratio).

The life judgment unit is configured to compare the accumulated operation time with the second judgment time and output a second judgment signal when the accumulated operation time becomes equal to the second judgment time. The timing adjustment unit is configured to vary timing at which the life judgment unit outputs the first judgment signal. The timing adjustment unit is configured to vary timing at which the life judgment unit outputs the second judgment signal. The indication unit is configured to indicate, upon receiving the first judgment signal from the life judgment unit, a first level of the end of life with the light source kept turned on. The indication unit is configured to indicate, upon receiving the second judgment signal from the life judgment unit, a second level of the end of life. The second level of the end of life is later than the first level of the end of life.

An induction lamp lighting device includes an induction coil arranged adjacent to an induction lamp; a direct current power supply circuit for outputting a direct current voltage; a high-frequency power supply circuit for converting the direct current voltage to an alternating current voltage and supplying the alternating current voltage to the induction coil; and a control circuit for controlling the direct current power supply circuit and the high-frequency power supply circuit. The control circuit performs a startup preparation operation by which to control the high-frequency power supply circuit so that, immediately after the alternating current voltage begins to be outputted from the high-frequency power supply circuit to the induction coil, the alternating current voltage is gradually increased to such a voltage value as not to generate arc discharge in the induction lamp and then kept at the voltage value for a specified time.

An electric-discharge lamp lightning device includes a first frequency controller for sweeping a switching frequency so that the output of an inverter is gradually increased in order to allow an electric-discharge lamp to be started and lighted, and a second frequency controller for detecting the output power of the inverter by a current flowing in a resonant circuit and controlling the switching frequency so that the output power is set to be a target value after the discharge lamp is started and lighted. The first frequency controller includes a holding means for holding the switching frequency just after the lighting detection when the output power is smaller than the target value at the lighting detection of the electric-discharge lamp by a lighting detection circuit.

There is provided an electrodeless discharge lamp lighting device with small size and low cost by simplifying a noise suppression part and a lighting apparatus having the electrodeless discharge lamp lighting device. A counter circuit of a frequency signal generating circuit repeatedly generates a frequency signal of which the amplitude is varied in a multi-step shape on the basis of an oscillation period of an oscillation circuit. An oscillation circuit outputs an oscillation signal of a frequency corresponding to the amplitude of the frequency signal. A drive circuit drives a switching element of an inverter circuit at the frequency of the oscillation signal and the inverter circuit applies a high-frequency voltage generated by the switching operation of the switching element to an induction coil to start up and light the electrodeless discharge lamp. That is, a high-frequency voltage which is varied at three discrete frequencies f1, f2, and f3 is repeatedly and periodically applied to the induction coil and thus a magnetic-component noise generated from a discharge lamp lighting device is distributed into three frequency components.

An electronic ballast for a discharge lamp includes a predictive circuit and a correction circuit in addition to a power conversion circuit including an inverter circuit and a resonant circuit, a drive circuit and a frequency control circuit. The inverter circuit applies load voltage across a load circuit including the lamp via the resonant circuit. The predictive circuit predicts a resonance frequency of the combination of the resonant circuit and the load circuit after ignition of the lamp. The resonance frequency is predicted based on an input signal representing the load voltage in the period of time from the start of sweep of the inverter circuit's operating frequency through a time point immediately after ignition of the lamp. The correction circuit changes the end frequency of the sweep to the resonance frequency.

A dimmable electronic ballast for an electrodeless discharge lamp comprises an inverter circuit, a resonance circuit, an induction coil and a start circuit. The start circuit has a variable time constant. The start circuit sweeps a drive frequency of the inverter circuit through a time constant for start or restart so that the voltage applied across the coil is raised from voltage lower than start voltage and restart voltage for starting and restarting the lamp to voltage higher than the start voltage and the restart voltage. The time constant for start during a start period for starting the lamp is larger than the time constant for restart during a restart period for restarting the lamp.
