DETAILED DESCRIPTION OF THE INVENTION

(22) Referring now to the figures, and to FIGS. 1 and 2A-2C in particular, a well-known and widely used SCOTTSDALE® canopy luminaire 20 is shown mounted to a deck 22 of canopy 24, such as a canopy typically found located over fuel pumps at petroleum service stations.

(23) As shown in FIGS. 1, 2A-2C, 4I and 4G, the SCOTTSDALE® canopy luminaire 20 includes a generally rectangular fixture base 26 (FIGS. 2A-2C and 4G) located beneath the canopy deck 22 and a lamp socket housing 28 (FIG. 4I) that extends upwardly from the fixture base 26 and through an opening (not shown) provided in the canopy deck 22. The fixture base 26 and the lamp socket housing 28 are typically integrally formed as a die-cast aluminum unit which is installed and supported by the canopy deck 22.

(24) The SCOTTSDALE® canopy luminaire 20 shown in FIG. 1 utilizes a vertically oriented high intensity discharge (“HID”) lamp 30, such as a metal-halide lamp, that is mounted to extend downwardly below the fixture base 26, with the light-emitting section of the HID lamp 30 being enclosed by a frame and lens assembly 32 that is hingedly connected to the fixture base 26. The lens 34 is typically made of glass, such as prismatic glass, and the lens frame 36 provided for supporting the glass lens 34 is typically made of an extruded plastic material. A reflector 38, such as a specular reflector, is mounted beneath the fixture base 26, with a base of the HID lamp 30 extending through an opening provided in the reflector 38 and electrically coupling to a lamp socket 40 (see FIG. 2C) that is supported within the lamp socket housing 28. The light-emitting section of the HID lamp 30 extends beneath the reflector 38 as shown in FIG. 1 to provide a uniform downward projection of light. The hinged connection of the frame and lens assembly 32 to the fixture base 26 allows the frame and lens assembly 32 to be pivoted from a closed position as shown in FIG. 1 to an open position pivoted away from the fixture base 26 about the cooperating hinge structure 42, 44 (see FIGS. 2A and 2B) located on the same respective sides of the lens frame 36 and fixture base 26 so that a user can access the HID lamp 30 mounted in the lamp socket 40 for removal and replacement thereof as may be necessary.

(25) As in FIGS. 1, 4I and 7, the SCOTTSDALE® canopy luminaire 20 of FIG. 1 includes a ballast housing 46 that is mounted above the canopy deck 22 and is operatively connected to the lamp socket housing 28 as shown in FIG. 4I. The ballast housing 46 is also typically made of die-cast aluminum and defines one or more chambers for housing control components (not shown), such as a transformer, capacitor and ignitor, within the ballast housing 46 which is closed by a removable top cover 48 as shown in FIG. 7.

Nos. 6,497,499, 6,059,422 and 5,662,407 to which the reader is referred, each assigned to the common Applicant and incorporated herein by reference in their respective entireties.

(27) As will be described in greater detail below, while the SCOTTSDALE® canopy luminaire 20 has been found to provide superior lighting performance and robust reliability for its intended lighting applications, recent advances in LED lighting technology has made it desirable in the lighting industry to retrofit the HID lamp-based SCOTTSDALE® canopy luminaire 20 shown in FIG. 1 with an alternative LED-based lighting technology.

(28) To that end, referring now to FIGS. 2-9, a retrofit method and retrofit LED canopy luminaire assembly 50 according to one embodiment of the present invention is shown and described in connection with FIGS. 2G, 2H and 5-7.

(29) According to one embodiment, the HID lamp-based SCOTTSDALE® canopy luminaire 20 shown in FIG. 1 is retrofitted with the retrofit LED canopy luminaire assembly 50 by first disconnecting and removing the frame and lens assembly 32 from the fixture base 26 of the SCOTTSDALE® canopy luminaire 20 as shown in FIG. 2A. Next, as shown in FIG. 2B, the HID lamp 30 and reflector 38 are removed from the fixture base 26 by unscrewing the HID lamp 30 from the lamp socket 20, and removing fasteners 52 used to secure the reflector 38 to the fixture base 26. Further disassembly of the SCOTTSDALE® canopy luminaire 20 is shown in FIG. 2C wherein the lamp socket 40 supported in the lamp socket housing 28 is disconnected and removed from the fixture base 26. Lastly, disassembly of the retrofit LED canopy luminaire 20 may optionally include removal of the control components (not shown) from the ballast housing 46. Alternatively, the control components (not shown) may be electrically disconnected and simply left remaining in the ballast housing 46.

(30) As shown in FIGS. 2D, 2E and FIGS. 3A-3E, the retrofit LED canopy luminaire assembly 50 according to one embodiment includes an annular retrofit adaptor bracket 54 having a radially inward inner wall 56, a radially outward outer wall 58 and a connecting web 60 extending between the inner and outer walls 56, 58.

As shown most clearly in FIGS. 3A and 3B, the opening 62 includes a notch 64 formed as part of the opening 62.

(31) Further referring to FIGS. 3A and 3B, the retrofit adaptor bracket 54 includes four vertically oriented mounting posts 66 located within a cavity 68 defined by the inner wall 56, the outer wall 58 and the connecting web 60 which may be unthreaded and configured to receive four respective fasteners 65, such as self-drilling fasteners, to secure the retrofit adaptor bracket 54 to the canopy deck 22 as shown in FIGS. 2E and 2F according to one embodiment, with the central opening 62 of the retrofit adaptor bracket 54 receiving the fixture base 26 within the central opening 62 so that the retrofit adaptor bracket 50 surrounds the fixture base 26 as shown in FIG. 2F.

(32) As shown in FIGS. 2G, 2H and 5-7, the retrofit LED canopy assembly 50 of the present invention includes a retrofit LED canopy luminaire 70 according to one embodiment which is shown in various stages of being mounted to the retrofit adaptor bracket 54 according to the exemplary embodiment.

(33) In one embodiment, the retrofit LED canopy luminaire 70 may comprise the SCOTTSDALE® SCM LED canopy luminaire as shown in FIGS. 2G, 2H and 5-7 that is commercially available from the Applicant, LSI Industries, Inc. In an alternative embodiment, the retrofit LED canopy luminaire may instead comprise the SCOTTSDALE® Vertex™ SCV LED canopy luminaire 72, also commercially available from the Applicant, LSI Industries, Inc, as will be described in connection with FIGS. 9-14.

(34) As shown in FIGS. 2G, 2H and 5-7, the retrofit LED canopy luminaire 70 includes a housing 74 which encloses a central array of LED's 76 as shown in FIG. 9 that are located within an optical chamber 77 (see FIG. 9). The housing 74 supports a central lens 78, such as a clear tempered glass lens, through which light emanating from the central array of LED's 76 projects downwardly to an area located below the retrofit LED canopy luminaire 70.

(35) Referring to FIGS. 2G and 6, the exemplary retrofit LED canopy luminaire 70 includes a plurality of electric leads 80 which extend from a base 82 of the retrofit LED canopy luminaire 70 and which are to be connected to respective electrical leads (not shown) extending from a remote power source (not shown) during the retrofit process as will be described in greater detail below.

(36) In one embodiment, the retrofit LED canopy luminaire 70 has five electrical leads 80 extending from the base 82. Three of the electrical leads 80 are provided for power connection of the retrofit LED canopy luminaire 70 to three respective electrical power leads (not shown) extending from the remote power source (not shown). The three electrical leads 80 may be provided for high voltage electrical connection (i.e., 480V+/−10%) to the power electrical leads (not shown) extending from the remote power source (not shown). The retrofit LED canopy luminaire 70 may also include two optional low voltage electrical leads (i.e., 0-10V) that are electrically connected to two respective electrical leads (not shown) extending from the remote power source (not shown), as described in greater detail below for control of the retrofit LED canopy luminaire 70.

(37) As shown in FIGS. 2H and 6, the retrofit LED canopy luminaire 70 is mounted to the retrofit adaptor bracket 54 via four fasteners 84, such as threaded machine screws, that extend through four respective apertures 86 (see FIG. 2H) that are located generally at the respective four corners of the retrofit LED canopy luminaire 70. The four fasteners 84 extending through the apertures 86 of the retrofit LED canopy luminaires are received in four vertically oriented threaded posts 88 that are located within the cavity 68 of the retrofit adaptor bracket 50 (see FIGS. 3B and 3E).

(38) In this embodiment, the retrofit adaptor bracket 54 is mounted to the canopy deck 22 with the cavity 68 of the retrofit adaptor bracket 54 facing the canopy deck 22, and with the connecting wall 60 of the retrofit adaptor bracket 54 being spaced from the canopy deck 22.

(39) With the lamp socket of the SCOTTSDALE® canopy luminaire already removed from the lamp socket housing 28 during the retrofit process as shown in FIG. 2C, a wire guide 90 according to one embodiment, as shown in FIG. 2F and FIGS. 4A-4G, is inserted into the lamp socket housing 28 and frictionally engaged with an inner cylindrical surface 92 (see FIG. 2F) of the lamp socket housing 28 so that the wire guide 90 is press-fit and frictionally retained within the lamp socket housing 28 as will be described in greater detail below.

(40) As shown in FIGS. 4A-4F, the wire guide 90 according to one embodiment includes a wire guide body 94 having one or more passageways 96 (two passageways 96 shown in FIGS. 4A-4F) that extend through wire guide body 94 and are configured to route the electrical leads 80 extending outwardly from the base 82 of the retrofit LED canopy luminaire 70 as shown in FIGS. 2G, 4H and 6, through the wire guide body 94, and into the ballast housing 46 as shown in FIG. 4I and as will be described in greater detail below.

(41) Referring now to FIGS. 4A-4H, the exemplary wire guide body 94 is made according to one embodiment from a plastic material, although other suitable materials are possible as well. In the embodiment shown in FIGS. 4A-4H, the wire guide body 94 includes the pair of at least partially separated passageways 96 that extend through the wire guide body 94 from an inlet end 98 of the wire guide body 94 to an opposite outlet end 100 of the wire guide body 94. Each of the pair of passageways 96 is configured to route selected different ones of the electrical leads 80 extending from the base 82 of the retrofit LED canopy luminaire 70 through the respective pair of passageways 96 of the wire guide body 94 and into the ballast housing 46.

(42) According to the exemplary embodiment of FIGS. 4A-4H, the pair of at least partially separated passageways 96 include a common inlet 102 located at the inlet end 98 of the wire guide body 94 and a pair of respective outlets 104 located at the remote and opposite outlet end 100 of the wire guide body 94.

(43) As shown in FIGS. 4A, 4E and 4F, the wire guide body 94 includes a saddle portion 106 located within the wire guide body 94 proximate the common inlet 102. The saddle portion 106 separates the common inlet 102 into the pair of at least partially separated passageways 96. For example, one of the passageways 96 may route the three high voltage power electrical leads 80 from the retrofit LED canopy luminaire 70 through the wire guide body 94, while the other passageways 96 may route the two lower voltage control electrical leads 80 also through the wire guide body 94, but separated from the high voltage electrical leads 80 extending through the other passageway. This may help to minimize interference caused by the high voltage electrical leads 80.

(44) As will be described in greater below, the common inlet 102 and saddle portion 106 that separate the two at least partially separated passageways 96 allows an installer to essentially blindly insert the electrical leads 80 of the retrofit LED canopy luminaire 70 into the wire guide body 94, with the electrical leads 80 being routed through the wire guide body 94 and into the ballast housing 46 for electrical connection with the electrical leads (not shown) extending from the remote power source (not shown).

(45) The electrical leads (not shown) extending from the remote power source (not shown) are routed to the ballast housing 46 via standard electrical conduit (not shown) that is mechanically coupled to one side wall of the ballast housing 46 in a known manner.

(46) As shown in the embodiment of FIGS. 4A, 4B, 4E and 4F, the common inlet 102 of the two at least partially separated passageways 96 may be circular in transverse cross-section, and each of the pair of respective outlets 104 of the two passageways 96 may also be circular in transverse cross-section. A diameter of the common inlet 102 may be greater than a respective diameter of each of the pair of respective outlets 104.

(47) Still referring to FIGS. 4A-4E and 4G, the exemplary wire guide body 94 includes a plurality of circumferentially spaced mounting pillars 108 (four shown in FIGS. 4A-4E and 4G) extending in a direction parallel to a longitudinal axis of the wire guide body 94. Each of the mounting pillars 108 is configured to frictionally engage with the inner cylindrical surface 92 of the lamp socket housing 28 so that the wire guide body 94 may be press-fit and frictionally retained within the lamp socket housing 28.

(48) In the embodiment shown in FIGS. 4A-4E and 4G, each of the plurality of mounting pillars 108 comprises a respective elongated arcuate mounting tab 110 extending in a direction parallel to the longitudinal axis of the wire guide body 94 which frictionally engage with the cylindrical inner surface 92 of the lamp socket housing 28.

(49) Each of the lamp socket housing 28 and the wire guide body 94 may include respective cooperating keying structure 112, 114 that is configured to orient the wire guide body 94 in a predetermined rotational orientation within, and relative to the lamp socket housing 28. For example, the keying structure 112 of the wire guide body 94 may include as least one pin 116 extending in a direction parallel to a longitudinal axis of the wire guide body 94 and toward a top wall 118 of the lamp socket housing 28, and the keying structure 114 of the lamp socket housing 28 may include at least one aperture 120 formed in the top wall 118 of the lamp socket housing 28 that is configured to receive the at least one pin 116 of the wire guide body 94 as shown in FIGS. 4G and 4I.

(50) The wire guide body 94 may be funnel-shaped between the common inlet 102 and the saddle portion 106 as shown in FIGS. 4A-4D. A pair of transverse webs 122 may be provided on the wire guide body 94, with one of the transverse webs 122 extending in one direction between the pair of passageways 96, and the other of the transverse webs 122 extending in a transverse direction between the keying structure 112 provided on the wire guide body 94.

(51) With the wire guide body 94 press-fit into the lamp socket housing 28 as shown in FIGS. 4H and 4I, the pair of outlets 104 of the two passageways 96 respectively align with two apertures 124 (see FIGS. 4G and 4I) provided on a top wall 125 of the light socket housing 28.

(52) During the retrofit installation of the retrofit LED canopy luminaire 70, the installer inserts the electrical leads 80 extending from the retrofit LED canopy luminaire 50 into the common inlet 102 of the wire guide body 94, with the electrical leads 80 being separately guided and routed as desired through the wire guide body 94, through the pair of apertures 120 formed in the top wall 125 of the light socket housing 28, and into the ballast housing 46 for electrical connection with the electrical leads (not shown) extending from the remote power source (not shown). The two passageways 96 of the wire guide body 94 neatly group the two separated bundles of electrical leads 80 extending from the retrofit LED canopy luminaire 70 (i.e., the high voltage leads and the low voltage leads) so that they may be easily inserted by the installer through the top wall 118 of the lamp socket housing 28 and into the ballast housing 46 as shown in FIGS. 4H and 4I.

(53) With the retrofit LED canopy luminaire 70 securely mounted to the retrofit adaptor bracket 54, and with all of the necessary electrical connections of the respective electrical leads 80 being made within the ballast housing 46, the installation of the retrofit LED canopy luminaire 70 is complete as shown in FIGS. 5 and 7.

(54) With the retrofit LED canopy luminaire 70 mounted to the retrofit adaptor bracket 54 as shown in FIGS. 5 and 7, the retrofit LED canopy luminaire 70 and retrofit adaptor bracket 54 provide an aesthetically pleasing appearance and a low profile for the retrofit LED canopy luminaire 70 located beneath the canopy.
