Abstract:
A flashlight carriable on one's person and comprising:(a) a unitary, one piece, hollow main barrel having a sidewall, a closed end and an open end; (b) a light emitting assembly removably attached to the open end of the main barrel so as to be removable as a unit, and including: i) an end cover having a light penetrating hole through one end of the end cover; ii) a female insulation sleeve located in the end cover, and having a hollow interior and a bottom wall with a central hole therethrough; iii) a metallic electrically conductive element mounted on the bottom wall within the female insulation sleeve, the metallic electrically conductive element having central opening aligned with the central hole in the bottom wall, first and second conductor feet extending from opposite sides thereof, a length of the first conductor foot being greater than a length of the second conductor foot; iv) a male insulation block on the female insulation sleeve, and having two through holes with a stepped portion communicating with each through hole; v) a light emitting diode (LED) located in the end cover and having first and second electrodes extending therefrom, the electrodes extending through the two through holes in the male insulation block, each electrode engaging one of the stepped portions such that the first electrode contacts the end cover and the second electrode contacts the first conductor foot; vi) an electrically conductive cap movably located in the female insulation sleeve having a portion extending through the central hole and the central opening, and an outwardly extending edge within the female insulation sleeve; and, vii) a biasing member acting on the electrically conductive cap so as to bias the cap in a position wherein the outwardly extending edge contacts the metallic electrically conductive element; and c) at least one battery located in the main barrel and having a terminal in contact with the electrically conductive cap, whereby movement of the light emitting assembly relative to the main barrel moves the electrically conductive cap between a first position wherein the outwardly extending edge contacts the electrically conductive element, thereby lighting the LED, and a second portion wherein the outwardly extending edge is displaced away from the electrically conductive element, thereby turning off the LED.
