摘要： An electronic track lighting system comprises a power supply filter circuit having an input connected to an alternating current power supply AC, a rectifier circuit connected to an output of the power supply filter circuit, an inverter circuit connected to an output of the rectifier circuit and outputting a high frequency voltage by on/off operation of switching elements therein, a lamp load, and a power track providing supply voltage to the lamp load. The lighting system further comprises a first unit which is interposed between the AC power supply and an input of the power track and includes at least the power supply filter circuit, and a second unit which is provided as a structure independent from the first unit, is connected to the power track and outputs a high frequency voltage to the lamp load.

摘要： An LED dimming includes: current adjusting means (constant current circuit) for variably controlling a magnitude of a current flowing through an LED load; switching means (transistor) for intermittently controlling the current flowing through the LED load; and dimming controlling means (microcomputer) for controlling the current adjusting means and the switching means upon receiving a dimming signal outputted from a dimmer. In a case where the dimming signal outputted from the dimmer is on a higher brightness side than a predetermined level, the dimming controlling means flows a continuous current though the LED load, and dims the LED load based on a magnitude of the flowing current, and in a case where the dimming signal outputted from the dimmer is on a lower brightness side than the predetermined level, the dimming controlling means flows a pulse current through the LED load, and changes a mean value of waveforms of the pulse current, thereby dims the LED load. In this LED dimming apparatus, noise is less likely to occur even in a case where such an LED current is large, and brightness is less likely to vary even in a case where a dimming degree is increased.
