ABSTRACT:
A multi-function lighting device in the nature of a miniature flashlight and which can serve as a miniature lantern or lamp, as well as a miniature flashlight, and as a miniature signaling device. The lighting device includes a housing with a head for directing light axially outwardly in the nature of a collimated beam, so that the device can function as a flashlight. Connected to the head end is a transparent or translucent sleeve which is slidable with respect to the light source. Thus, when the head and the sleeve are shifted axially outwardly, the light source is located within the transparent or translucent sleeve. When the light source is energized, light will emanate primarily through the translucent or transparent sleeve and the amount of light emanating from the head end is substantially reduced. The device is also effective to operate as a signaling device in which the light is energized and de-energized in a sequencing or so-called "blinking" operation. Various embodiments of the device are disclosed.
