    摘要： 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. Thus, the portable lighting device of the present invention may be constructed with much fewer components and at a much lower cost than conventional flashlights.

    摘要： A card light assembly comprising a generally flat polymeric tray having inner and outer surfaces and a pair of ends, a peripheral rim on the inner surface, an electrochemical cell-receiving recess in the inner surface, and a LED-receiving recess at one of the ends, an annular electrical separator and a disc-type electrochemical cell in the cell receiving recess, a LED in said LED-receiving recess, the LED having two leads, one of which is in abutment with the cell and the other of which is spaced from the cell by the separator. A pressure sensitive adhesive label extends over the inner surface, and over the cell, and is adhered to the housing inner surface to thereby retain the separator and cell within the assembly. At least one of the tray and label is flexibly depressible at the separator and cell for pressing the other lead against the cell to temporarily energize the LED.
