Abstract An incandescent lamp device is disclosed as including a cylindrical cagelike shell and a cylindrical socket housing at the top thereof, said cagelike shell encircling an inverted incandescent lamp bulb depending from a socket in the socket housing. A cylindrical diffuser base attached to a diffuser is removably attached to the lower end of the cylindrical cagelike shell such that the diffuser surrounds the incandescent lamp bulb to a point slightly removed from the base of the bulb, thereby providing a convenient means for ready removal of the bulb and cooling air emission. A further cooling construction is also described for providing longer bulb life and protecting the plastic parts of the device from excessive heat.
An incandescent lamp device comprising a housing including a socket housing portion, a shell attached to said socket housing portion and a diffuser base portion removably attached to said shell, a bulb attached in said socket housing portion, a diffuser disposed within said shell and attached to said diffuser base portion such that removal of said diffuser base portion achieves removal of said diffuser permitting ready access to said bulb for removal, said shell depending from said socket housing portion, said diffuser base portion being attached to the base of said shell, said bulb being inverted and depending from said socket housing portion and said diffuser being upstanding from said diffuser base portion, said diffuser including an upper end terminating short of the underside of said socket housing portion to define an annular ventilation opening.
