Lighting device with dynamic bulb position

摘要

A portable, self-contained lighting device with improvements in bulb positioning, switching, and electrical contact wherein (a) the bulb position changes axially depending on the presence or absence of the power source; (b) the rotating switch is positioned essentially directly above the bulb; and (c) the electrical contact strip is preloaded against the switch assembly in the "off" position and has an over-travel capacity of up to about 50% with a compensating flexible knee capable of changing by up to about 40 DEG .
