Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
100 words
A multi-lamp fixture accommodating at least two fluorescent lamps comprising: lamp holding means adapted to receive said lamps; circuit means connected to said holding means for supplying electrical power to said lamps; reflecting means introduced into said fixture and having longitudinally spaced ends received by the portion of said holding means adapted to hold a fluorescent lamp in place of a removed fluorescent lamp, configured to reflect outwardly from said fixture to the intended areas to be illuminated a substantial portion of the illumination received from the lamp or lamps remaining therein which would otherwise be absorbed within the fixture.
Claim 2
Dependent Claim
100 words
A multi-lamp fixture accommodating at least two fluorescent lamps comprising: lamp holding means adapted to receive said lamps; circuit means connected to said holding means for supplying electrical power to said lamps; reflecting means introduced into said fixture and having longitudinally spaced ends received by the portion of said holding means adapted to hold a fluorescent lamp in place of a removed fluorescent lamp, configured to reflect outwardly from said fixture to the intended areas to be illuminated a substantial portion of the illumination received from the lamp or lamps remaining therein which would otherwise be absorbed within the fixture.
Claim 3
Dependent Claim
34 words
A fixture as in claim 1, wherein the reflecting means includes a reflecting surface spaced laterally from and positioned along substantially the entire longitudinal length of the remaining lamp or lamps in the fixture.
Claim 4
Dependent Claim
16 words
A fixture as in claim 2, wherein the reflecting surface is made of an aluminum alloy.
Claim 5
Dependent Claim
46 words
A fixture as in claim 2, wherein the longitudinal ends of the reflecting means includes supporting caps attached to the longitudinal ends of the reflecting surface, to be inserted into the respective portion of the lamp holding means from which a fluorescent lamp has been removed.
Claim 6
Dependent Claim
101 words
An assembly, for replacing a fluorescent lamp which is removed from a multi-lamp fixture including a lamp holder for each lamp, for improving the lighting efficiency of the fixture comprising: reflecting means configured to reflect outwardly from said fixture to the intended areas to be illuminated a substantial portion of the illumination received fronm the remaining lamps which would otherwise be absorbed within the fixture; means at the longitudinal ends of the assembly adapted for insertion into the lamp holder for a lamp removed from the fixture to thereby have the fixture support the assembly in place of the removed lamp.
Claim 7
Dependent Claim
101 words
An assembly, for replacing a fluorescent lamp which is removed from a multi-lamp fixture including a lamp holder for each lamp, for improving the lighting efficiency of the fixture comprising: reflecting means configured to reflect outwardly from said fixture to the intended areas to be illuminated a substantial portion of the illumination received fronm the remaining lamps which would otherwise be absorbed within the fixture; means at the longitudinal ends of the assembly adapted for insertion into the lamp holder for a lamp removed from the fixture to thereby have the fixture support the assembly in place of the removed lamp.
Claim 8
Dependent Claim
51 words
An assembly as in claim 5, wherein the reflecting means includes a reflecting surface adapted to be spaced laterally from and positioned along substantially the entire longitudinal length of the remaining lamp or lamps in the fixture when the assembly is supported in the fixture in place of a removed lamp.
Claim 9
Dependent Claim
16 words
An assembly as in claim 6, wherein the reflecting surface is made of an aluminum alloy.
Claim 10
Dependent Claim
33 words
An assembly as in claim 6, wherein said means at the longitudinal ends of the assembly comprise caps attached to the reflecting surface and adapted to be inserted into said lamp holding means.
Claim 11
Dependent Claim
94 words
A fixture including at least two fluorescent lamps and respective holding means adapted to receive each lamp comprising: reflecting means introduced in place of a selected removed one of said fluorescent lamps, configured so as to reflect outwardly from said fixture to the intended areas to be illuminated a substantial portion of the illumination received from the remaining lamp or lamps which would otherwise be absorbed within the fixture; means for supporting the reflecting means comprising means at the longitudinal ends of the reflecting means received by the holding means for the removed lamp.
Claim 12
Dependent Claim
94 words
A fixture including at least two fluorescent lamps and respective holding means adapted to receive each lamp comprising: reflecting means introduced in place of a selected removed one of said fluorescent lamps, configured so as to reflect outwardly from said fixture to the intended areas to be illuminated a substantial portion of the illumination received from the remaining lamp or lamps which would otherwise be absorbed within the fixture; means for supporting the reflecting means comprising means at the longitudinal ends of the reflecting means received by the holding means for the removed lamp.
Claim 13
Dependent Claim
32 words
A fixture as in claim 9, wherein the reflecting means includes a reflecting surface spaced laterally from and positioned along substantially the entire longitudinal length of the remaining lamps in the fixture.
Claim 14
Dependent Claim
16 words
A fixture as in claim 10, wherein the reflecting surface is made of an aluminum alloy.
Claim 15
Dependent Claim
29 words
A fixture as in claim 10, wherein the supporting means includes caps, attached to the longitudinal ends of the reflecting surface, to be inserted into said lamp holding means.
Claim 16
Independent Claim
115 words
A method of providing a more efficient multi-lamp fluorescent lamp fixture including a number of respective holding means each adapted to receive a respective fluorescent lamp and circuit means connected to said holding means for supplying electrical power to said lamp comprising the step of: introducing into said fixture, in place of a selected fluorescent lamp, reflecting means having a configuration for reflecting outwardly from said fixture to the intended areas to be illuminated a substantial portion of the illumination received from the remaining lamps which would otherwise be absorbed within the fixture, and supporting the reflecting means in the fixture by engaging its longitudinal end with the respective holding means for the removed lamp.
