DETAILED DESCRIPTION OF EXAMPLE EMBODIMENTS

Example embodiments disclosed herein are directed to a light emitting diode (LED) luminaire or light fixture and devices for rotatably mounting the light fixture to a pole or surface. The example embodiments provide the capability to modify a typically wall-mounted light fixture for use as a rotatably adjustable flood light.

FIGS. 1-9C provide various views of a luminaire with trunnion mounting system in accordance with one example embodiment. Referring now to FIGS. 1-8 and 9A-C, the luminaire 100 includes a light fixture 105 coupled to a trunnion mounting system 125. The light fixture 105 includes a fixture housing 110, one or more light sources 115 and an electrical component housing 120. In an example embodiment, the fixture housing 110 and the electrical component housing 120 may be a single housing. In certain example embodiments, the fixture housing 110 acts as a heat sink. For example, the fixture housing 110 can have a front side and an opposing back side. The front side can include a plurality of fins that can extend vertically along all or a portion of the front side of the housing 110.

In certain example embodiments, the light sources 115 are LED light sources are an disposed generally along a bottom side 307 of the fixture housing 110, within a light cavity 107, to emit light generally down from the housing to a desired area to be illuminated. The light sources 115 can be LED chip on board, LED arrays or discrete LEDs positioned along the bottom side of the fixture housing 110 and can further include one or more substrates, such as a PCB or MCPCB, for providing electrical power and control to the light sources 115. While not shown, the lighting cavity 107 can also include one or more reflectors disposed within the cavity and a lens covering the entrance to the cavity 107 from the bottom side 307 of the fixture housing 110. In certain example embodiments, the lens is a glass or polycarbonate lens.

The electrical component housing 120 or “back-box” can be removably coupled to the back side of the fixture housing 110. In certain example embodiments, the back-box 120 is removably coupled to the fixture housing 110 using coupling devices, which can include screws, bolts, clips, cotter pins, tabs and slots or any other coupling devices known to those of ordinary skill in the art. As best seen in FIG. 11B, the back box 120 can have a back wall 1165 and four side walls 1170 extending out from the back wall 1165. The back wall 1165 and four side walls can define a cavity 1150 for containing electrical components (such as wires, LED drivers, and the like) for receiving a source of power and providing that power to the light sources 115.

The back box 120 can also include a recess 1145 along one of the side walls 1170 for receiving a tab (as best described hereinafter with regard to FIGS. 10-14). The recess 1145 can be an indentation along the surface of the side wall 1170 that is sized and shaped to receive and hold or prevent undue movement of the tab. The back box 120 can also include one or more elongated slot apertures 1155 that can receive a portion of a screw or other coupling device therethrough to couple the back box 120 to the trunnion mounting system 125, a knuckle mounting system 1002 (see FIGS. 10-14C) or an electrical junction box (not shown). The back box 120 also includes one or more conduit apertures 1160 for receiving electrical wiring therethrough.

The trunnion mounting system 125 includes a surface mounting bracket 130 and a mounting plate 155 rotatably coupled to the surface mounting bracket 130. The surface mounting bracket 130 can be a u-shaped bracket and can include elongated apertures 220 for mounting the bracket 130 to a wall, floor, ceiling or any other type of surface with bolts, screws or other coupling devices and a conduit aperture 905 for receiving electrical wiring therethrough. The surface mounting bracket 130 can be made from metal or plastic and can be a single piece or two separate pieces, which could then be generally in the form of two L-shaped brackets.

The mounting plate 155 can be symmetrical. In certain example embodiments, the mounting plate 155 is square and/or is sized and shaped to match the size and shape of the back wall 1165 of the back box 120. In addition, or in the alternative, the mounting plate 155 is sized and shaped to cover the entire back gasket disposed along the exterior of the back wall 1165 of the back box 120 to provide a water-tight or water resistant seal between the back wall 1165 and the mounting plate 155.

As best seen in FIG. 2, the mounting plate 155 includes one or more screw bosses 205 that can each receive a screw 210 for coupling the mounting plate 155 to the back wall 1165 of the back box 120. In certain example embodiments, the mounting plate 155 includes four screw bosses 205 and the head of the screw 210 can be positioned inside the cavity 1150 of the back box 120 to couple the back box 120 to the mounting plate 155. The mounting plate 155 can also include one or more elongated protrusions 230 extending up from a front surface of the mounting plate 155. Each elongated protrusion 230 can be sized and shaped to fit into or cover the elongated slot apertures 1155 in the back wall 1165 of the back box 120 to further seal the back box 120 from water.

The mounting plate 155 can also include two adjustment brackets 140 coupled to and extending orthogonally or substantially orthogonally out from opposing sides of the mounting plate 155. Each adjustment bracket 140 can include an arcuate slot aperture 160 and a pivot point aperture 145. In certain example embodiments, the arcuate slot aperture 160 spans an arc of between 90-270 degrees and in certain embodiments about 180 degrees. The adjustment bracket 140 can further include tick marks 225 or other means for indicating the amount of rotation of the mounting plate 155 with respect to the surface mounting bracket 130. In one example embodiment, each tick mark 225 represents a fifteen degree rotation. Each adjustment bracket 140 is rotatably coupled to one of the vertical portions or arms of the surface mounting bracket 130 with bolts, screws or other coupling devices at the aperture 145. This coupling at the aperture 145 can function as the pivot point between each adjustment bracket and its respective portion of the surface mounting bracket 130. Another coupling device 150, such as a screw or bolt can be coupled to the surface mounting bracket 130 and extend through the arcuate slot aperture 160 to control the rotation of the mounting plate 155 with respect to the surface mounting bracket 130.

When the light fixture 105 is coupled to the trunnion mounting system 125 by way of coupling the back box 120 to the mounting plate 155, the light fixture 105 can be rotatable about one axis, through the pivot point 145. One way to rotate the fixture 105 is to loosen the coupling device 150, then adjust the light fixture 105 to the desired position and then re-tighten the coupling device 150. FIGS. 4-8 provide views of different positions of adjustment for the luminaire 100 using the trunnion mounting system 125. For example, FIGS. 5 and 6 show a smaller fixture housing 110, such that the mounting plate 155 contacts the surface 135 along opposing limits of rotation. FIGS. 7 and 8 present a larger fixture housing 110 such that the fixture housing 110 itself contacts the surface 135 along opposing limits of rotation. Those of ordinary skill in the art will recognize that, absent other changes, making the vertical portions of each surface mounting bracket 130 longer and moving the pivot point 145 further away (vertically) from the surface 135, can provide an increased range of rotation for the light fixture 105. In certain example embodiments, the light fixture 105 has a range of rotation of between 90-270 degrees. Alternatively, the light fixture 105 has a range of rotation of between 90-180 degrees. For example, in one embodiment, the light fixture 105 may rotate between 0 degree and 180 degrees relative to an initial position of the light fixture 105.

The trunnion mounting system 125 can be provided with the light fixture 105 or sold as a separate retrofit kit to change the light fixture 105 from a wall-mounted light fixture to a rotatably adjustable flood light. In either event, the trunnion mounting system 125 can also include the visor system 305, which is described in greater detail below in FIG. 15.

FIGS. 10-14C provide various views of a luminaire with knuckle mounting system in accordance with example embodiments. Referring now to FIGS. 10-14C, the luminaire 1000 includes a light fixture 105 coupled to a knuckle mounting system 1002. The light fixture 105 is substantially the same as that described above with regard to FIGS. 1-9 and will not be repeated. The knuckle mounting system 1002 can include a tie rod 1005, a set of teeth 1012 along one end of the tie rod 1005, a knuckle stem 1015 rotatably and adjustably coupled to the teeth 1012, and a mounting plate 1020 coupled to the knuckle stem 1015.

The mounting plate 1020 can include a mounting surface 1130 and a lip 1135 extending up from the mounting surface 1130. One or more screw bosses 1115 can be coupled to or positioned adjacent the mounting surface 1130. The example embodiment can include four screw bosses 1115, each capable of receiving a screw 1120 or other coupling device for removably coupling the mounting plate 1020 to the back wall 1165 (shown in FIG. 11B) of the back box 120. In certain example embodiments, the mounting plate 1020 can have side walls 1125 that extend vertically or angularly out from a center portion of the mounting plate 1020 and provide a cavity in the mounting plate 1020 to hold or provide a pathway for electrical components, such as wires 1110.

The example mounting plate 1020 can also include an alignment feature to align the mounting plate 1020 with the back wall 1165 of the back box 120. In certain example embodiments, the alignment feature is an alignment tab 1140. The alignment tab 1140 can extend orthogonally or angularly up from a front surface of the mounting plate 1020, such as from the lip 1135. The alignment tab 1140 can be sized and shaped to fit into the recess 1145 along one of the side walls 1170 of the back box 120. By placing the alignment tab 1140 within the recess 1145, the screw bosses 1115 will be aligned with the screw apertures in the back wall 1165 of the back box 120. While the example alignment feature has been described with reference to the mounting plate of the knuckle mounting system 1002, the alignment feature could also be similarly used with and included on the mounting plate 155 of the trunnion mounting system 125 of FIG. 1.

In certain example embodiments, the mounting plate 1020 is square and/or is sized and shaped to match the size and shape of the back wall 1165 of the back box 120. In addition, or in the alternative, the mounting plate 1020 is sized and shaped to cover the entire back gasket disposed along the exterior of the back wall 1165 of the back box 120 to provide a water-tight or water resistant seal between the back wall 1165 and the mounting plate 1020.

The knuckle stem 1015 extends from a back side of the mounting plate 1020 and can be integrally formed with the mounting plate 1020 or coupled to the mounting plate 1020. The knuckle stem 1015 can include a set of teeth (not shown) that are complimentary to and engage the teeth 1012 on one end of the tie rod 1005. Both the tie rod 1005 and the knuckle stem 1015 can include complimentary apertures for receiving a coupling device 1010, such as a screw or bolt. One or both of the complimentary apertures can be threaded or through holes. The coupling device 1010 can define the axis of rotation for the light fixture 105 with respect to the tie rod 1005. The end opposite the teeth 1012 on the tie rod can be threaded 1105 and can be coupled to a surface 1025 either by providing a threaded aperture in the surface or by extending the threaded end 1105 through an aperture in the surface and coupling a nut 1030 to the threaded portion 1105 of the tie rod 1005. In certain example embodiments, the tie rod 1005 can include a hollow portion for routing electrical wires 1110 through the tie rod 1005 and the mounting plate 1020 to the back box 120 to provide electrical power to the light source 115 in the light fixture 105.

FIGS. 12 and 13 present different views of the rotational capability of the light fixture 105 using the knuckle mounting system 1002. For example a person can loosen the coupling device 1010, which causes the teeth 1012 on the tie rod 1005 to disengage from the complimentary teeth on the knuckle stem 1015. The light fixture 1015 can then be rotated to the desired position about an axis substantially at the aperture for the coupling device 1010. Then the coupling device 1010 can be tightened such that the teeth 1012 on the tie rod 1005 re-engage the teeth on the knuckle stem 1015 to hold the light fixture 105 in place. Those of ordinary skill in the art will recognize that, absent other changes, making the vertical length of the tie rod 1005 longer and moving the pivot point 1010 further away (vertically) from the surface 1025, can result in an increased range of rotation for the light fixture 105. In certain example embodiments, the light fixture 105 has a range of rotation of between 90-270 degrees. Alternatively, the light fixture 105 has a range of rotation of between 90-180 degrees. For example, in one embodiment, the light fixture 105 may rotate between 0 degree and 90 degrees relative to an initial position of the light fixture 105.

The knuckle mounting system 1002 can be provided with the light fixture 105 or sold as a separate retrofit kit to change the light fixture 105 from a wall-mounted light fixture to a rotatably adjustable flood light. In either event, the knuckle mounting system 1002 kit can also include the visor system 305, which is described in greater detail below in FIG. 15.

FIG. 15 illustrates a visor system 305 that can be removably coupled to the light fixture 105 in accordance with certain example embodiments. Referring now to FIGS. 3 and 15, the example visor system 305 can be used in conjunction with the trunnion mounting system 125 or the knuckle mounting system 1102 or without either and just with the light fixture 105. The visor system 305 includes a visor 1500 and an optional impact guard 1515. The visor 1500 can be removably coupled to the bottom end 307 of the fixture housing 110 and generally disposed about the area housing the light sources 115. The visor 1500 includes a first end 1510 that is positioned about the exterior of the bottom end 307 of the fixture housing 110. The visor 1500 can then be clamped or coupled to the fixture housing 110 by tightening a screw or other coupling device 1530 through the clamping mechanism 1525. For example, as the coupling device 1530 is tightened in the clamping mechanism 1525, the inner diameter of the first end 1510 of the visor 1500 is reduced, thereby securing the visor 1500 to the bottom end 307 of the fixture housing 110.

The visor 1500 can include a longer side wall 1505 that extends out farther generally than the other side walls to reduce the amount of light emitted by the luminaire 100 in the direction of that side wall 1505. For example, the larger side wall 1505 can be used to reduce the amount of uplight emitted by the luminaire 100. As indicated above, the visor system 305 can optionally include the impact guard 1515. In certain example embodiments, the impact guard 1515 is an impact resistant lens that can be made from polycarbonate material. In certain example embodiments, the impact guard 1515 includes tabs 1517, 1519 that extend out from opposing edges of the impact guard 1515. Further, the visor 1500 can include slots 1520 in each of side walls 1507 and 1509. The impact guard 1515 can be coupled to the visor 1500 by slidably inserting the tabs 1517, 1519 into the respective slots 1520 in each of the respective side walls 1507, 1509. The impact guard 1515 provides a protective barrier in front of a glass lens (not shown) and the light sources 115 to protect each from damage and to reduce ingress of environmental elements into the area of the light source 115.

While not shown, the visor system 305 can be rotated 180 degrees and coupled to the bottom end 307 of the fixture housing 110 in a manner that does not provide uplight reduction but still positions the impact guard 1515 in front of the glass lens and the light sources 115 to prevent them from damage. The visor 1500 and the impact guard 1515 can have different sizes to fit different sizes of the fixture housing 110.

FIGS. 16A-F illustrate example installation steps of the luminaire with trunnion mounting system. FIG. 16A shows an attachment step of a surface mounting bracket, such as the surface mounting bracket 130, to a surface. FIG. 16B shows how the position of a mounting plate (e.g., the mounting plate 155) may be adjusted by loosing a coupling device (e.g., the coupling device 150 shown FIG. 1) using a tool such as a screw driver. For example, the mounting plate may be rotated to a position shown in FIG. 16C.
