摘要： A lamp socket for supporting an HID lamp includes a hollow casing having a lamp mounting opening defined at one end and the opposite end closed; an electrode carrier member disposed inside the casing; a center electrode disposedon the electrode carrier member at a location coaxial with an axis perpendicular to a plane of the lamp mounting opening and engageable with a center contact point in a mouthpiece of a lamp to be received in the lamp socket; a peripheral electrode disposed on the electrode carrier member at a location offset laterally from the center electrode and also from the axis for engagement a peripheral contact point in the mouthpiece of the lamp; an electrode shielding member disposed within the casing for movement between projected and retracted positions; and a coil spring for biasing the electrode shielding member to the projected position and operable to permit the electrode shielding member to move towards the retracted position against a biasing force thereof in response to insertion of the lamp mouthpiece into the lamp mounting opening. The electrode shielding member when in the retracted position permits the center and peripheral electrodes to be electrically engaged with the center and peripheral contact points in the lamp mouthpiece when the electrode shielding member is moved to the retracted position, but the electrode shielding member when in the projected position substantially conceals the center and peripheral electrodes.

摘要： An LED driver circuit is provided for protecting one (or more) LEDs connected in series from over-current damages which may result from a short circuit condition. The driver circuit includes a current control circuit for receiving an input signal from a power source and providing a current output for powering the LED. A voltage sensor detects a voltage across the LED. An LED current restriction circuit such as a switching element restricts a current flow into the LED. A short circuit response circuit controls the LED current restriction circuit dependent on a comparison between the voltage detected by the voltage sensor and a predetermined threshold value. When the detected voltage is less than or equal to the threshold value, the response circuit determines a short circuit, and a signal is sent to the current restriction circuit to restrict current flow into the one or more LEDs.

摘要： A safety ballast for a discharge lamp capable of interrupting the supply of the electric power upon failure of starting the lamp. The ballast includes a converter providing a DC power voltage from a DC voltage source, a booster providing a boosted DC voltage to a starter which generates, based upon the boosted DC voltage, a starting voltage for starting the lamp, and an inverter receiving the DC power from the converter to provide an AC power for operating the lamp. The booster includes a capacitor which is charged by the DC power and accumulate the boosted voltage. A controller monitors a load condition of the lamp and issues a disable signal when a no-load condition continues over a predetermined starting period. The inverter includes a plurality of switching elements one of which is regulated to be turned on in response to the no-load signal for establishing a supply path of supplying the boosted voltage from the booster's capacitor through the switching element to the starter. The one switching element is also controlled to be turned off in response to the disable signal for interrupting the supply path. Thus, when the no-load condition continues over the predetermined starting period as indicative of the that the lamp has been removed or the lamp reaching its end of life, the booster's capacitor bearing the boosted voltage is disconnected from the starter, applying no voltage to the starter and therefore preventing the starter from being activated to generate unnecessary starting voltage.
