Abstract

To provide for maximum light intensity in a selected mode of operation--th or flashlight mode or warning flasher mode, an elongated tubular housing has a body portion (2) and a head portion (3), the two portions being connected together by a hollow tube (17) secured preferably to the head portion (3) and slideable within the body portion. A reflector system (5) is secured to the head portion, and the halogen incandescent lamp seated on the body portion. For flashlight operation, the reflector system is fitted over the halogen incandescent lamp, and light from the lamp is directed axially outwardly of the flash lamp; for blinker operation, the entire head portion is pulled upwardly, along with the reflector for a distance, such that the reflector will clear the halogen incandescent lamp (16), thus providing for 360.degree. light radiation--with respect to the axis of the lamp--and essentially directing all light from the halogen incandescent lamp for blinder or warning purposes. The tubular element (17) preferably is ribbed, and colored with a warning color, such as amber or red.

Dependent claims

Combination flashlight-warning light (1) having

an elongated tubular housing including
a cylindrical body portion (2) and a head portion (3) which is, at least in part, cylindrical;
an optical system (5, 8, 10) including a reflector (5) located within the housing;
a halogen incandescent lamp (16) located at an end zone of the body portion (2) facing the head portion (3),
the body portion (2) defining a battery chamber (13) therein;
means (17) axially slideably connecting the head portion (3) and the body portion (2) to provide for axially slideable movement of the head portion with respect to the body portion ,
wherein said slideable connection means (17) comprises
a hollow cylindrical tube (17) telescopically received within the cylindrical body portion (2) and the at least in part cylindrical head portion (3), said hollow cylindrical tube surrounding at least the halogen incandescent lamp, regardless of the sliding position of the hollow cylindrical tube, and wherein the portion (18) of the hollow cylindrical tube surrounding the halogen incandescent lamp (16) is transparent, said hollow cylindrical tube forming a connection element for said body portion (2) and said head portion (3) while permitting relative movement thereof;
and
wherein, the reflector (5) is secured to the head portion (3) and the slideable connection means (17) has a slide distance large enough to remove the reflector secured to the head portion from the bulb of the halogen incandescent lamp and expose at least a filament of the halogen incandescent lamp (16) to a free space between the body portion (2) and the head portion (3) to provide for 360.degree. light radiation--with respect to a longitudinal axis of the elongated tubular housing-from the halogen incandescent lamp (16).
