Abstract:
1. A lighting device comprising: a housing; a light source for generating a light beam; a power source for providing power to the light source; and light control circuitry for turning the light source on and off and controlling intensity of the light beam, wherein the light control circuitry comprises a switch and a controller for controlling intensity of the generated light beam, wherein the light control circuitry processes a signal generated during activation of the switch and adjusts the intensity of the light beam as a function of activation of the switch such that the intensity of the light beam generated by the light source is incrementally increased and decreased in a repeated ramp cycle between a maximum beam intensity and a minimum beam intensity while the switch is continuously activated, wherein the light control circuitry adjusts intensity of the light beam as a function of the amount of time that the switch is activated, and wherein the light control circuitry further controls the light source to generate a flashing light beam when the light beam is at one of the maximum and minimum beam intensities.
