Abstract
Abstract A combined fluorescent lamp and spotlight which is simple to manufacture and assemble has a trough-shaped body member of generally rectangular section with tubular cylindrical projections at its ends and a chassis member received on the trough-shaped body member and closing the open side thereof, the chassis member mounting a bulb holder for a bulb, fluorescent tube mounting members, a printed circuit board, a switch and battery contacts such that all the electrical components requiring connection together are all provided on the chassis member which can be completely wired before being engaged on the trough-shaped body member to close the open side thereof. A cover of transparent material and of elongate arch section overlies a fluorescent tube mounted on the mounting member of the chassis member and end members, each with an aperture therethrough to receive respective ones of the tubular projections of the body portion and each have a peripheral flange overlapping the cover and the body portion and thereby retaining the cover in position on the body portion. End caps engage with integral screw threads the tubular projections of the body portion and are received each in a recess in the outer end face of the respective one of the end members thereby retaining the end members in position on the body portion. One of the end caps has a transparent end wall and a reflector therein receiving the bulb mounted in the bulb holder.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
206 words
A combined fluorescent lamp and spotlight, comprising in combination: a body member of generally rectangular section with one open side and having tubular cylindrical projections with screw threads at the ends of said body member; a chassis member received on said body member and closing said open side thereof, said chassis member having mounted thereon a bulb holder, fluorescent tube mounting members, electrical circuit components, a switch and battery contacts; a cover of transparent material and of elongate arch section to overlie a fluorescent tube mounted on said tube mounting members of said chassis member; a pair of end members each formed with an aperture therethrough, each of which said apertures receives a respective one of said tubular projections of said body member, and a peripheral flange to overlap said cover and thereby retain said cover in position on said body member; and end caps with screw threads to engage with said screw threads of said tubular projections of said body member and to engage a respective one of said end members to retain said end members in position on said body member, one of said end caps having a transparent end wall and a reflector therein to receive a bulb mounted in said bulb holder.
Claim 2
Dependent Claim
206 words
A combined fluorescent lamp and spotlight, comprising in combination: a body member of generally rectangular section with one open side and having tubular cylindrical projections with screw threads at the ends of said body member; a chassis member received on said body member and closing said open side thereof, said chassis member having mounted thereon a bulb holder, fluorescent tube mounting members, electrical circuit components, a switch and battery contacts; a cover of transparent material and of elongate arch section to overlie a fluorescent tube mounted on said tube mounting members of said chassis member; a pair of end members each formed with an aperture therethrough, each of which said apertures receives a respective one of said tubular projections of said body member, and a peripheral flange to overlap said cover and thereby retain said cover in position on said body member; and end caps with screw threads to engage with said screw threads of said tubular projections of said body member and to engage a respective one of said end members to retain said end members in position on said body member, one of said end caps having a transparent end wall and a reflector therein to receive a bulb mounted in said bulb holder.
Claim 3
Dependent Claim
81 words
A combined fluorescent lamp and spotlight as claimed in claim 1, wherein said switch has an operating portion and is slidably mounted with respect to said chassis member such that upon engagement of said chassis member on said body member said switch operating portion projects through an aperture in the adjacent wall of said body member, and said switch sliding to its final position with respect to said chassis member as said chassis member is finally engaged on said body member.
Claim 4
Dependent Claim
86 words
A combined fluorescent lamp and spotlight as claimed in claim 1, wherein each of said end members has a recess in the outer end face open at opposite sides thereof so that said end cap is received therein and located within the profile of said end member so that force can be applied to the circumferential face of said end cap so that said end cap can be readily rotated to tighten or loosen its screw threaded engagement with said tubular projection of said body member.
Claim 5
Dependent Claim
30 words
A combined fluorescent lamp and spotlight as claimed in claim 3, wherein said circumferential face of each said end cap is provided with means whereby it can be securely gripped.
Claim 6
Dependent Claim
39 words
A combined fluorescent lamp and spotlight as claimed in claim 4, wherein, in its fully screwed on position, each said end cap has its outer end face flush with the outer end face of the respective said end member.
Claim 7
Dependent Claim
39 words
A combined fluorescent lamp and spotlight as claimed in claim 3, wherein, in its fully screwed on position, each said end cap has its outer end face flush with the outer end face of the respective said end member.
Claim 8
Dependent Claim
54 words
A combined fluorescent lamp and spotlight as claimed in claim 1, wherein said chassis member and said body member form between them an elongated battery chamber; said cover and said chassis member forming between them an elongated chamber for the fluorescent tube, which chamber is substantially coextensive with and parallel to the battery chamber.
Claim 9
Dependent Claim
68 words
A combined fluorescent lamp and spotlight as claimed in claim 7, wherein said cover and said body member form between them an electrical component chamber receiving therein a portion of said chassis member having thereon said bulb holder, and electrical circuit components at the one end of and apart from said battery and fluorescent tube chambers; said cover being opaque adjacent said chamber between cover and body member.
Claim 10
Dependent Claim
81 words
A combined fluorescent lamp and spotlight as claimed in claim 8, wherein said switch has an operating portion and is slidably mounted with respect to said chassis member such that upon engagement of said chassis member on said body member said switch operating portion projects through an aperture in the adjacent wall of said body member, and said switch sliding to its final position with respect to said chassis member as said chassis member is finally engaged on said body member.
