Description

Technical Field

[0001] The present disclosure relates generally to lighting, and more particularly to remote power system components and ladder-type racks of remote power system components. Background Art

[0002] Some outdoor lighting systems (e.g., sports lighting systems) may have a support structure (such as a pole and frame) that does not support a lamp head with an integrated driver (e.g., a light emitting diode (LED) lamp head). In such a case, a remotely located power system may be used to provide power to the lamp head. For example, the remote power system may be attached to a lamp pole (e.g., a base near the lamp pole) that is remote from the lamp head located at the top of the lamp pole. In some cases, it may be challenging to attach components of the remote power system to the pole, particularly when the alternating current (AC) wires and the direct current (DC) wires should be isolated from each other. Therefore, a solution that provides proper installation of the remote power system and a properly installed remote power system may be desirable.

[0024] In the following paragraphs, exemplary embodiments will be described in more detail with reference to the accompanying drawings. In the description, well-known components, methods and / or processing techniques are omitted or briefly described. In addition, the reference to different features of the embodiments does not mean that all embodiments must include the referenced features.

[0025] Figure 1 An outdoor lighting system 100 according to an exemplary embodiment is shown, and Figure 2 According to an exemplary embodiment, Figure 1 A remote power system 102 of an outdoor lighting system 100. In some exemplary embodiments, the outdoor lighting system 100 includes a lamp head assembly 120 and a remote power system 102. The lamp head assembly 120 can be connected to the pole 104 at a top portion of the pole 104. The remote power system 102 can be attached to the pole 104 or another structure (e.g., a wall) at a location away from the lamp head assembly 120. The remote power system 102 can receive AC power, for example, via a cable (e.g., one or more wires) that is routed upward through the pole 104 from below the remote power system 102. The remote power system 102 can generate DC power from the AC power and provide the DC power to a lamp head (e.g., lamp head 122) of the lamp head assembly 120. For example, the remote power system 102 can provide DC power to the lamp head of the lamp head assembly 120 via one or more cables that are connected to a power connection box and routed into the pole 104. The lamp head of the lamp head assembly 120 can be an LED lamp head.

[0026] In some exemplary embodiments, the remote power system 102 may include remote power units 106, 108 and a power connection box 110. The remote power unit 106 is attached to a mounting rack 210, and the remote power unit 108 is attached to a mounting rack 212 (e.g., Figure 2 104). The components of the remote power unit 106 and the mounting rack 210 may be attached to the pole 104 by one or more straps (e.g., strap 112) extending around the pole 104. In particular, the remote power unit 106 may be attached to the mounting rack 210, which is attached to the pole 104 by one or more straps. Alternatively or additionally, other attachment structures may be used to attach the mounting rack 210 to the pole 104. The components of the remote power unit 108 and the mounting rack 212 may be attached to the pole 104 by one or more straps (e.g., strap 114) extending around the pole 104. In particular, the remote power unit 108 may be attached to the mounting rack 212, which is attached to the pole 104 by one or more straps. Alternatively or additionally, other attachment structures may be used to attach the mounting rack 210 to the pole 104. The power connection box 110 may be attached to the bracket (at Figure 8C ), the bracket is attached to the pole 104 by one or more straps (e.g., strap 116). Alternatively or additionally, other attachment structures can be used to attach the power connection box 110 to the pole 104.

[0027] In some demonstrative embodiments, the remote power unit 106 may include a housing 202 and heat sink structures 204, 206. The heat sink structures 204, 206 may be separate structures from the housing 202, or may be an integral part of the housing 202. The housing 202 may be designed to protect the components within the housing 202 from water exposure. For example, the remote power unit 106 may include one or more drivers (e.g., LED drivers) that receive AC power and generate DC power that is provided to some of the lamp heads of the lamp head assembly 120. The drivers of the remote power unit 106 may be accessed by opening a door 222 of the housing 202.

[0028] In some exemplary embodiments, the remote power unit 108 may include a housing 208 and a heat sink structure similar to the heat sink structure of the remote power unit 106. The housing 208 may be designed to protect the components inside the housing 208 from water exposure. For example, the remote power unit 108 may include one or more drivers (e.g., LED drivers) that receive AC power and generate DC power that is provided to some of the lamp heads of the lamp head assembly 120. The drivers of the remote power unit 108 may be accessed by opening the door 224 of the housing 208.

[0029] In some exemplary embodiments, the cables 214, 216 may extend from the remote power unit 106 to the power connection box 110. For example, the cable 214 may be used for an AC power connection between the power connection box 110 and the remote power unit 106, and the cable 216 may be used for a DC power connection between the remote power unit 106 and the power connection box 110. To illustrate, AC power (e.g., from an electric utility) may be provided to the remote power unit 106 via the power connection box 110 through the cable 214. The remote power unit 106 may generate DC power from the AC power, and may provide the DC power to some of the lamp heads of the lamp head assemblies 120 through the cable 216 via the power connection box 110 and one or more cables connected to the power connection box 110 and routed through the interior of the pole 104 to the lamp head assemblies 120. The cables 214, 216 may be routed to the power connection box 110 through the wiring pathways provided by the mounting racks 210, 212. The cables 214, 216 may be routed to the power connection box 110 through the isolation panels of the mounting racks 210, 212 as described below. Figures 4A-4D The mounting racks 400 are routed separately from each other in the manner described.

[0030] In some exemplary embodiments, the cables 218, 220 may extend from the remote power unit 108 to the power connection box 110. For example, the cable 218 may be used for an AC power connection between the power connection box 110 and the remote power unit 108, and the cable 220 may be used for a DC power connection between the remote power unit 108 and the power connection box 110. To illustrate, AC power (e.g., from an electric utility) may be provided to the remote power unit 108 via the power connection box 110 through the cable 218. The remote power unit 108 may generate DC power from the AC power, and may provide the DC power to some of the lamp heads of the lamp head assemblies 120 through the cable 220 via the power connection box 110 and one or more cables connected to the power connection box 110 and routed to the lamp head assemblies 120 through the interior of the pole 104. The cables 218, 220 may be routed to the power connection box 110 through a wiring pathway provided by the mounting rack 212. The cables 218, 220 may be routed to the power connection box 110 through a partition plate of the mounting rack 212 as described below. Figures 4A-4D The mounting racks 400 are routed separately from each other in the manner described.

[0031] In some exemplary embodiments, the cables 214, 218 may be routed behind and / or within the power connection box 110 separate from the cables 216, 220 to provide isolation of the AC power lines and the DC power lines. The power connection box 110 may include separate chambers for the AC power connection and the DC power connection, as described below with respect to Figures 8A-8D The chamber of the power connection box 110 can be accessed by opening the door 226 of the power connection box 110 .

[0032] Because the remote power system 102 provides DC power to the lamp head assembly 120 when positioned remotely from the lamp head assembly 120, the lamp head of the lamp head assembly 120 does not need to include a local power source. By eliminating the need for the lamp head to incorporate a driver, the remote power system 102 is able to replace non-LED lamp heads with LED lamp heads. By providing separate wiring pathways and chambers for AC power connections and DC power connections, the remote power system 102 improves isolation of AC and DC power, which can, for example, reduce signal interference. The isolation of the remote power units 106, 108 from each other by at least a portion of the mounting rack 210 located below the remote power unit 106 can provide sufficient spacing for effectively dissipating heat from the remote power units 106, 108.

[0033] Although Figure 1 and 21, but in some alternative embodiments, the remote power system 102 may include more or fewer remote power units without departing from the scope of the present invention. In some alternative embodiments, one or more of the remote power units 106, 108 and the power connection box 110 may be attached to the pole 104 at a different location than shown without departing from the scope of the present invention. In some exemplary embodiments, the cables described above with respect to AC power may be used for DC power connections, and the cables described above with respect to DC power may be used for AC power connections without departing from the scope of the present disclosure.

In some exemplary embodiments, the remote power system 900 includes remote power unit assemblies 904, 906, 908, 910 and a power connection box 912 attached to a pole 902. For example, the remote power unit assemblies 904 and 908 can be attached to the pole 902 using mounting structures (such as mounting fasteners 914), and the remote power unit assemblies 906 and 910 can be attached to the pole 902 using structures (such as mounting fasteners 916) (as will be readily understood by those of ordinary skill in the art). As will be readily understood by those of ordinary skill in the art, the power connection box 912 can be attached to the pole 902 using structures such as mounting fasteners 918.

[0066] In some exemplary embodiments, the remote power system 900 may be configured to Figure 2The remote power system 102 of the embodiment of the present invention can provide DC power to a lamp head (e.g., an LED lamp head) located at the top portion of the pole 902 in the manner described above. For example, the remote power system 900 can provide DC power to the lamp head assembly (e.g., Figure 1 The lamp head assembly 120 shown provides DC power.

[0067] In some exemplary embodiments, the cables between the remote power unit assemblies 904, 906 and the power connection box 912 may be generally arranged in a manner as to Figure 2 Because the remote power unit assemblies 908, 910 are on the opposite side of the pole 902 from the power connection box 912, the cables between the remote power unit assemblies 908, 910 and the power connection box 912 can be routed at least partially through the flexible conduits 920 and 922 (as will be readily understood by those of ordinary skill in the art). In general, the cables used for the AC power connection between each of the remote power unit assemblies 904-910 and the power connection box 912 can be routed separately from the cables used for the DC power connection between the corresponding one of the remote power unit assemblies 904-910 and the power connection box 912.
