ABSTRACT:
A mobile light is disclosed that produces a high level of illumination without glare using the DC power of a vehicle's battery and charging system. The mobile light uses a high-intensity discharge lamp with a control circuit that initially ignites the lamp using a voltage multiplier circuit and that maintains illumination of the lamp using an FET switching circuit that applies a lower AC voltage to the lamp. The microprocessor also periodically adjusts the power delivered to the lamp to compensate for adverse conditions, such as high temperatures within the work light, or a high or low DC input voltage. The microprocessor also periodically senses the level of illumination provided by the lamp and adjusts the voltage applied to the lamp accordingly.
