Abstract: A connector 11 includes a housing 12, a connector insertion portion 12f arranged in the housing 12 for insertion of a wire-side connector 30 at an end of an electric wire 31, and a connector connection portion (input terminals 14) arranged in the housing 12 for connection with the wire-side connector 30 when the wire-side connector 30 is inserted into the connector insertion portion 12f. The connector 11 includes a latch 20 located on a face of the housing 12 excluding the end face in which the connector insertion portion 12f is arranged such that the latch does not intersect with a hypothetical plane including that end face. The connector 11 also has legs 17. The legs 17 and the connector connection portion (input terminals 14) are each formed by parts of an L-shaped conductive member 15, and the legs 17 also function as electrode terminals.

Abstract: A power supply apparatus for a light source includes an input-side rectifier (32) which converts an input AC signal to a DC signal, and a high-frequency inverter (36) which converts the DC signal to a high-frequency signal. An output-side rectifier (42) converts the high-frequency signal to a DC output signal for application to the light source. Power detecting means (52) detects the power supplied to the light source through the application of the DC output signal thereto, and develops a power representative signal. A control circuit (38), a summer (54) and an error amplifier (58) cooperate to control the high-frequency inverter (36) in accordance with the power representative signal in such a manner that power of a predetermined value can be supplied to the light source. An input current detector (60) detects the input AC signal current value and develops an input current representative signal.

Abstract: A power supply apparatus useful for starting and driving a discharge lamp 22 includes a DC-to-DC converter 16 for converting a DC signal from a DC power supply to a second DC signal having a predetermined magnitude which is supplied to the lamp. A current detector 24 develops a DC current representative signal representing DC current supplied to the lamp from the DC-to-DC converter. A combination of the current detector 24, a DC voltage detector 26 and a multiplier 30 develops a DC power representative signal representing DC power supplied from the DC-to-DC converter to the lamp. An error amplifier 32 develops a DC current error signal representing the difference between the DC current representative signal and a predetermined DC current reference signal. An error amplifier 36 develops a DC power error signal representing the difference between the DC power representative signal and a predetermined power reference signal.
