    摘要： A control circuit for a light source comprises: a light source, a drive circuit applying a pulse width modulated (PWM) drive signal to the light source; and a pulse width modulator generating the PWM drive signal having a PWM ON time ratio responsive to a control signal and a PWM drive frequency that varies over a range of frequencies repeatedly and substantially continuously. A method for controlling a light source comprises: applying a pulse width modulated (PWM) drive signal to the light source; generating the PWM drive signal having a PWM ON time ratio responsive to a control signal and having a PWM drive frequency that is varied over the range of frequencies repeatedly and substantially continuously. The PWM drive signal causes the light source to produce light at the varying frequency, whereby light at a frequency exhibited by a moving object does not continuously illuminate a moving object.

    摘要： A portable light may comprise: a light body for receiving a source of electrical power; a light source for producing light when energized; and a switch assembly for selectively coupling the source of electrical power with said light source for energizing the light source to produce light. The portable light may have a light head and a pivot assembly including a pivotable joint for pivoting the light head towards and away from the light body and a rotatable joint for rotating the light head relative to the light body; and/or may have a handle assembly coupled to the light body by a handle pivot so as to be pivotable away from and toward the light body. A releasable latch assembly that retains the handle housing adjacent the light body may be provided.
