Definitions

  • the present invention relates to lighting, and more specifically, to luminaires including solid state light sources.
  • a typical fluorescent tube lamp socket (commonly referred to in the art as a tombstone socket or simply a tombstone) is adapted to receive the one or more pins traditionally located on the end caps of a fluorescent lamp.
  • the tombstone provides electricity to the lamp as well as mechanical support for the lamp.
  • a tombstone is sometimes a removable part of a larger system (e.g., fluorescent lamp fixture, display case, refrigeration case, etc.) and is sometimes integral with the larger system.
  • Solid state light sources such as but not limited to light emitting diodes (LEDs), organic light emitting diodes (OLEDs), polymer light emitting diodes (PLEDs), and the like
  • LEDs light emitting diodes
  • OLEDs organic light emitting diodes
  • PLEDs polymer light emitting diodes
  • fixtures/ luminaires containing the same are being used more frequently to replace traditional light sources (e.g., incandescent, halogen, low-pressure discharge (i.e., fluorescent), high-pressure discharge (i.e., metal halide, sodium, etc.), etc.) and/ or fixtures containing the same.
  • traditional light sources e.g., incandescent, halogen, low-pressure discharge (i.e., fluorescent), high-pressure discharge (i.e., metal halide, sodium, etc.), etc.
  • fixtures containing the same are being used more frequently to replace traditional light sources (e.g., incandescent, halogen, low-pressure discharge (
  • retrofit solid state light source-based lamps designed to replace typical incandescent lamps are designed with the same base, so that they will fit into the same socket, and thus may be operated from the same power source (i.e., AC mainline power).
  • Some retrofit solid state light sources (either lamps or fixtures) designed to replace fluorescent tube lamps do not include the same bi-pin bases of the fluorescent tube lamp, which of course are designed to fit into tombstone sockets. This is because the solid state light sources typically are not able to be operated via the ballast that powers a fluorescent lamp. Rather, a solid state light source typically requires its own power supply (also referred to as a driver), whether as a separate unit or integral with the retrofit lamp / fixture.
  • the retrofit solid state light source(s) (in either a lamp or a fixture), however, is supposed to occupy the same space.
  • the solid state light source lamp/fixture is secured in the space previously occupied by a fluorescent tube lamp by using metal snap brackets that need to be fastened to a stationary object using screws, or by removing the existing tombstone sockets and replacing them with a particular part designed for that particular lamp/ fixture. This is time-consuming and costly. The costs, in terms of time and money, are increased in situations where the tombstone sockets were not designed to be removed from the existing installation.
  • Embodiments of the present invention provide a cover for the typical fluorescent tombstone sockets that mates to a connector that is easily attached to the retrofit solid state light source(s) (in either a lamp or a fixture).
  • Embodiments provide an easy-to-install, tool-free and/ or almost tool-free way to secure a retrofit lamp/ fixture to a stationary object.
  • Some embodiments include mating connectors that could be employed on a number of different objects for retrofit applications as well as new construction applications.
  • Other embodiments provide for a single piece that covers a tombstone socket and is additionally mechanically attached (for example, via screws) to the existing fixture.
  • a luminaire adapter in an embodiment, there is provided a luminaire adapter.
  • the luminaire adapter includes: a tombstone cover, wherein the tombstone cover comprises a housing that defines a slot opening to accept a tombstone socket and a pair of snap connectors; and a light source bracket, wherein the light source bracket comprises a top portion configured to connect to a bottom portion, wherein the bottom portion includes a pair of snap receivers configured to receive the pair of snap connectors, and wherein the top portion and the bottom portion define an opening to receive a luminaire.

  • the first tab and the second tab may be oriented such that the snap opening is parallel to the housing top.

  • FIGs. 6A-6B and 7A-7B show embodiments of a luminaire adapter 700 formed by a tombstone cover 650 and a light source bracket 610.
  • the tombstone cover 650 includes a pair of snap receivers 660 and 670, while the light source bracket 610 includes a pair of snap connectors 620 and 630.
  • FIG. 7A shows a luminaire 701 with the light source bracket 610 attached at one end, and the tombstone cover 650 placed over a tombstone socket (not shown as covered by the tombstone cover 650).
  • FIG. 7B shows the light source bracket 610 connected to the tombstone cover 650, as described in greater detail below, which allows the luminaire 701 to replace a fluorescent lamp without having to remove the tombstone sockets that previously held and powered the fluorescent lamp.
  • FIG. 6A shows the light source bracket 650 in greater detail.
  • the light source bracket 650 is shaped so as to accept the luminaire 701 (shown in FIGs. 7A-7B ).
  • the light source bracket 650 includes an opening between a top portion 601 and a bottom portion 602, which, in some embodiments, are two separate pieces that are join together and in some embodiments are different parts of the same single piece.
  • the shape of the opening matches, at least in part, the shape of an end of the luminaire.
  • at least one end of a luminaire is inserted into the opening of the light source bracket 650.
  • the light source bracket 650 attaches to the luminaire 701 using any known mechanical connection, such as but not limited to screws, friction, tensioning, bonding (i.e., glue, cement, epoxy, etc.), or the like.
  • An outer portion of the light source bracket 650 includes the pair of snap connectors 620 and 630, which extend out from the light source bracket 650. Though the pair of snap connectors 620 and 630 are shown in FIG. 6A as linearly extending arms, each with a protruding tab to interact with the pair of snap receivers 660 and 670, the pair of snap connectors may take any known connecting shape.
  • a housing 680 of the tombstone cover 650 is generally shaped the same as the housing 111 shown in FIGs. 1-2 and 4-5 .
  • the housing 680 includes the pair of snap receivers 660 and 670 on a front wall 651 of the housing 680.
  • the pair of snap receivers 660 and 670 as shown in FIG. 6B are oppositely arrayed L-shaped clips protruding from the front wall 651 of the tombstone cover 650, the pair of snap receivers may take any known receiver shape that is able to mechanically accept the corresponding pair of snap connectors on the light source bracket 610. In some embodiments, a particular type of pair of snap receivers is able to accept multiple different types of snap connectors.
  • the pair of snap connectors 620 and 630 extend from the light source bracket 650 and/ or in the pair of snap receivers 660 and 670 to accommodate luminaires in any of the various spaces that held different types (and lengths) of fluorescent lamps, while still maintaining a solid and secure connection for the luminaire.
  • the light source bracket 650 includes a groove 625 that comes into contact with a corresponding post 665 located in (and/ or substantially in) the center of the tombstone cover 650. This allows the luminaire 701 to be centered without extra effort or measurements on the part of the installer, while taking into account the tolerances built into the luminaire adapter 700 to work with differently sized luminaires and tombstones, and also serves to help hold the luminaire 701 securly in place.
  • Embodiments have been described herein with relation to a luminaire, embodiments are not so limited. Embodiments may alternatively and/ or additionally be realized as a light engine/ module that fits within a luminaire housing, with the luminaire housing attaching to the light source bracket, without departing from the scope of the invention. Similarly, embodiments may alternatively and/ or additionally be realized as a retrofit lamp that fits within a luminaire housing, with the luminaire housing attaching to the light source bracket, without departing from the scope of the invention. Further, some embodiments may be considered a light engine/ module instead of a luminaire. In such embodiments, the light engine/ module connects to the light source bracket of a luminaire adapter, and fits in place of a fluorescent lamp. In such embodiments, the combination of the luminaire adapter(s) and the light engine/ module may itself be considered a luminaire.
