Abstract: 1. A lighting device (2) having a light housing (6) including a light source (42, 44), said light housing rotatably connected to a body, said body having a rotatable connection means (22) to allow the light housing to be adjacent said body to define a narrow space (90) accessible in a base to top direction. 2. A lighting device (2) having a light source (42,44), a tubular lens (40, 50) surrounding said light source, a reflector (56) cooperating with an end of said tubular lens opposite to said light source. 3. A light housing (6) or a method of assembling a light housing (6), said light housing having a first side and a second side, a first side having a mounting spigot (52, 54), a second side having an aperture (62, 63), a tubular lens (48, 50) can pass through the aperture so that one end of the tubular lens is received in the mounting spigot, said aperture and said mounting spigot being in alignment.

Abstract: A flashlight is disclosed having a body and a flashlight head in which a light bulb is mounted. The body includes a housing that defines a battery compartment, a pair of arms extending from a front end of the housing for mounting the flashlight head between opposing ends of the arms such that the flashlight head may be pivoted relative to the body, and a thumb wheel rotatably mounted in the housing and extending partially through the housing to engage the flashlight head such that the flashlight head pivots relative to the body as the thumb wheel is rotated. The thumb wheel may include gear teeth about its perimeter for engaging gear teeth formed in the round rear surface of the flashlight head.

Abstract: The invention relates to a housing which receives dry cells in an in-line or end to end orientation. The invention includes features which prevent the incorrect orientation by preventing dry cell terminals making contact with the necessary components. In this way, it prevents premature dissipation of dry cells or their impairment. The mechanism by which these features do this is to recess one terminal namely that terminal which would be contacted by the positive terminal of a dry cell. In this way, the negative terminal of a dry cell can never make electrical connection. Another feature of the invention is the provision of an aperture having a profile of a silhouette of a dry cell, which has advantages in low light situations, saves material, and allows for relatively easy extraction of dry cells from the cartridge.
Abstract: A portable lighting device according to the present invention includes a battery housing, a light source supported at a first end of the battery housing, and a shroud extending outward from the first end of the battery housing circumferentially around the light source. The shroud is preferably formed of a translucent material having a partially reflective inner surface for reflecting a portion of incident light emitted from the light source in a forward direction while allowing a portion of the incident light to be transmitted through the shroud and dispersed in peripheral directions. The shroud further preferably includes a diffusing outer surface for diffusing the incident light that is transmitted through the shroud. A shroud is preferably integrally formed with a collar portion as used for threading the integrated head structure onto the battery housing. Additionally, a protective lens cover that may include a collimating lens is also integrally formed in this head structure.
