    摘要： A high intensity discharge (HID) assembly comprises ballast circuits which includes a micro-controller, and an HID headlamp. In order to deter theft of the HID assembly from a vehicle, the micro-controller communicates with a vehicle computer, checks the VIN of the vehicle, and if the micro-controller does not recognize the VIN, causes the HID headlamp to operate in a flickering power output mode. The ballast circuits include a power control circuit, a lamp current regulator, a 400v regulator, a current sense circuit, a turn-on synchronization circuit, a shut down circuit, and a pulse width modulator.

    摘要： A temperature sensing circuit for a ballast for a HID lamp multiplexes the temperature measurement function with another function to reduce the number of pins required for the temperature measurement function performed by the microcontroller of the ballast. The circuit includes a microcontroller having a first A/D input/output pin, a second A/D input/output pin and a multifunction pin, a temperature measurement circuit connected to the second A/D pin, a timing circuit connected to the first A/D pin, and a switch connected to the multifunction pin, temperature measurement circuit and timing circuit. The switch activates the temperature measurement function by connecting the temperature measurement circuit to the multifunction pin in a first position and deactivates the function by disconnecting the temperature measurement circuit from the multifunction pin in a second position.

    摘要： A device used with a direct current power source for energizing a lamp. The device includes a plurality of input channels selectively connected to the power source for providing current to the lamp. For each input channel, the device includes a corresponding current sensing component connected to the input channel, and a corresponding bypass switch connected in parallel with the current sensing component. Each current sensing component produces a measurable signal as a function of current that is provided by the corresponding input channel. The device includes a controller connected to the current sensing components and the bypass switches. The controller identifies the input channel that is providing current to the lamp as a function of the measurable signals and controls the bypass switches based on the identified input channel. Particularly, the controller operates each bypass switch in a closed mode when the corresponding input channel is the identified channel so that current provided by the corresponding identified input channel bypasses the current sensing component.
