DETAILED DESCRIPTION OF THE INVENTION

[0026] Reference will now be made in detail to the presently preferred embodiments of the invention, one or more examples of which are illustrated in the drawings. Each example is provided by way of explanation of the invention, and not by way of limitation of the invention. For example, features illustrated or described as part of one embodiment may be used on another embodiment to yield a still further embodiment. It is intended that the present application include such modifications and variations as come within the scope and spirit of the invention.

[0027] A ceiling light LED retrofit kit 30 is disclosed.

[0028] Retrofit kit 30 may be understood in certain embodiments to be included in a combination with a fixture 10.

[0029] Fixture 10 may include a pre-installed base 12 attached to the interior ceiling 68 of a building. Base 12 may be understood to define a first longitudinal side 14 and an opposed second longitudinal side 16. Base 12 may also include a first electrical receptacle 21, a second electrical receptacle 22, a third electrical receptacle 23, and so forth. First electrical receptacle 21 and second electrical receptacle 22 may be configured and positioned for receipt of a linear fluorescent light tube disposed between them and energized by them.

[0030] Generally, retrofit kit 30 is adapted to conceal or obscure the pre-installed base 12 so as to provide the appearance that the fixture 10 is new or completely replaced. Retrofit kit 30 may include a light panel 40. Light panel 40 may define a first side 41 that faces fixture 10 and an opposed second side 42. In some embodiments, the light panel 40 may include a first angled wing 43 and a second angled wing 44. One or more light emitting diode 60 may be disposed on second side 42 of light panel 40. In certain embodiments, it may be found that disposing a light emitting diode 60 on first angled wing 43 or second wing 44 provides a more desirable path of illumination from light emitting diode 60. Retrofit kit 30 may also include a power supply 64, to energize the LED 60.

[0031] Retrofit kit 30 may also include a first profile 51 and second profile 52. The first profile 51 and/or second profile 52 may be integral with light panel 40, which may be disposed between the first profile 51 and the second profile 52. In other embodiments, first profile 51 and/or second profile 52 may be separate members that are attached to light panel 40, for example, at opposing, longitudinal edges of light panel 40.

[0032] Light panel 40, first profile 51, and second profile 52 may extend longitudinally from proximate the first electrical receptacle 21 to proximate the second electrical receptacle 22.

[0033] First profile 51 may extend from light panel 40 to first longitudinal side 14 of base 12 of fixture 10. Second profile 52 may extend from light panel 40 to the second longitudinal 16 of base 12 of fixture 10.

[0034] First profile 51 and second profile 52 may each be flat or may instead include a rib 59 that extends longitudinally from one end of the profile to the opposing end, respectively. Rib 59 may be optionally included to provide enhanced stiffness to first profile 51 and/or second profile 52

[0035] First profile 51 and second profile 52 may be attached to first longitudinal side 14 and second longitudinal side 16, respectively. With first profile 51 attached to first longitudinal side 14 and second profile 52 attached to second longitudinal side 16, first profile 51, second profile 52, light panel 40, and base 12 may define between them a raceway 62. Upon final assembly, electrical wiring in electrical communication with light emitting diode 60 may reside within raceway 62. Furthermore, power supply 64 for the LED 60 may be stored in raceway 62.

[0036] When attached to pre-installed base, the present ceiling light LED retrofit kit is adapted to conceal the prior components and to provide the appearance of a new or replaced light fixture.

[0037] FIG. 1 illustrates an embodiment of the present ceiling light LED retrofit kit. Base 12 of fixture 10 is attached to ceiling 68. Base 12 includes first longitudinal side 14 and second longitudinal side 16. As illustrated in FIG. 1, first electrical receptacle 21 and third electrical receptacle 23, which had previously been used in base 12 to hold and power a longitudinal fluorescent light tube, may be left within the ceiling light LED retrofit kit. As also illustrated, power supply 64, used to energize the LED, may be simply located within raceway 62.

[0038] In the embodiment illustrated in FIG. 1, light panel 40, first profile 51, and second profile 52 are integral. In other embodiments, first profile 51 and second profile 52 may be separate elements that have been attached to light panel 40.

[0039] First profile 51 is attached to first longitudinal side 14 of base 12 of fixture 10. Second profile 52 is attached to second longitudinal side 16 of base 12 of fixture 10.

[0040] A light emitting diode 60 may be disposed on second angled wing 44 of light panel 40. Light emitting diode 60 is in electrical communication with an electrical power source (not shown).

[0041] A lens 66 may be attached to light panel 40, as illustrated in FIG. 1. Lens 66 may be configured to provide a pleasing and esthetically attractive dispersion of light emitted from light emitting diode 60. FIG. 1 illustrates an angle A formed between the surface of first angled wing 43 and the surface of the lens 66, when attached.

[0042] FIG. 2 illustrates an embodiment of a retrofit kit 30. As depicted therein, retrofit kit 30 includes a first profile 51, extending longitudinally, and a second profile 52 extending longitudinally. First profile 51 and second profile 52 may include a plurality of apertures, for example, 70a and 70b, for attachment to base 12 of fixture 10.

[0043] FIGS. 3 and 4 are illustrations of an assembled LED retrofit kit. In FIG. 3, retrofit kit 30 includes a first profile 51, extending longitudinally, and a second profile 52 extending longitudinally. In this embodiment, first profile 51 and second profile 52 are separate. A lens 66 is illustrated as attached to first profile and second profile, such as by an endcap or clip, for example, 72 (shown in FIG. 7). As illustrated, first profile 51 and second profile 52 may include one or more longitudinal ribs, for example, 59, complimenting and corresponding to one or more endcap ribs. Second profile 52 is illustrated as attached to first longitudinal side 14 of base 12 of fixture 10.

[0044] FIG. 4 is an illustration of an assembled LED retrofit kit. Fixture 10, which includes second electrical receptacle 22, is illustrated in phantom. First profile 51 is illustrated as attached to first longitudinal side 14 of base 12 of fixture 10. Power supply 64 is illustrated as residing within raceway 62 and endcap 72 is shown in place upon the assembly.

[0045] FIG. 5 is a perspective view of an endcap 72, for use with one embodiment of the present ceiling light LED retrofit kit.

[0046] In particular applications, a plurality of light panels 40 may be disposed end to end in electrical series, for particular advantages. In such configurations, a splice 74 may be used at the juncture of any two abutting light panels 40. An embodiment of a splice 74 is depicted in FIG. 6.

[0047] FIG. 7 is a perspective view of an endcap 72, for use with one embodiment the present ceiling light LED retrofit kit. In this embodiment, endcap 72 includes one or more ribs that correspond the one or more longitudinal ribs, for example, 59, along the first profile 51 and the second profile 52, respectively.

[0048] In some applications, a plurality of light panels 40 may be disposed end to end in electrical series, for particular advantages. In such configurations, a splice 74 may be used at the juncture of any two abutting light panels 40. An embodiment of a splice 74 is depicted in FIG. 8. In this embodiment, the splice may include one or more corresponding ribs, for example, 59a and 59b, that correspond to the one or more longitudinal ribs, for example, 59, along the first profile 51 and the second profile 52, respectively.

[0049] The present invention further contemplates a method for retrofitting pre-installed fixtures or bases using the kit described herein. In one embodiment, the method may include the steps of: 1) identifying a fixture having a pre-installed base having a first longitudinal side and a second longitudinal side; 2) providing a ceiling light LED retrofit kit comprising: a first profile, an opposing second profile, and a light panel, the light panel being disposed between the first profile and the opposing second profile; 3) connecting the first profile to the first longitudinal side, and the second profile to the second longitudinal side of the pre-installed base; 4) providing a light emitting diode and electrically connecting it to the light panel; and 5) covering the light panel with a lens.

[0050] So configured, the ceiling light LED retrofit kit of the present invention offers several advantages, efficiencies, and optimizations. Because it is attached to an old fluorescent light fixture, added rigidity and strength is accomplished. For that reason, for example, thinner material may be used with first profile 51 and/or second profile 52, achieving material costs savings, yet providing sufficient structural strength. Similarly, because the present ceiling light retrofit kit does not require disassembly of the first, second, and so forth electrical receptacles 21, 22 of the earlier fixture 10, labor and disposal costs are avoided. (Such electrical receptacles are sometimes referred to as “tombstones” by those with skill in this technology). Furthermore, because the previously-used, now de-energized ballast for the fluorescent light tubes can be left within the base 12, additional labor and disposal time and cost savings are achieved. As yet still a further example, the finished assembly of the within ceiling light LED retrofit kit includes a lens, rather than a previously-exposed linear fluorescent light tubes, providing a more attractive appearance and also enabling the user to provide customer refraction from the light illuminating from light emitting diode 60, as may be desired in particular applications.

[0051] While the particular ceiling light LED retrofit kit as herein shown and described is fully capable of achieving the objects of the invention, it is to be understood that it is the presently preferred embodiment of the present invention and is thus representative of the subject matter that's broadly contemplated by the present invention. It is to be further understood that the scope of the present invention fully encompasses other embodiments that may become obvious to those skilled in the art. It is intended that the present invention includes such modifications and variations as come within the scope of the appended claim and their equivalents.
