設けたことを特徴とする調光器。 Dimming data is set by an up dimmer switch and a down dimmer switch consisting of a push button switch, and a counter means that steps up or down when each dimmer switch is turned on, and also controls the set dimming data. In a dimmer equipped with a dimmer control circuit that forms a phase control pulse of a phase control element based on the phase control pulse, and a phase control element that is controlled by the phase control pulse and dims the lighting load, each dimmer switch The dimming data set at the off operation timing is stored in the EEPROM.
After the power supply to the data writing means for writing to non-volatile memory such as and the dimming control circuit is stopped,
A dimmer comprising power failure compensating means for controlling a phase control element based on dimming data read from the nonvolatile memory to start dimming control of a lighting load when power is resupplied.
