Definitions

  • Embodiments of the technology relate generally to luminaires and more particularly to an outdoor luminaire with an accessible terminal block that receives AC power.
  • Luminaires such as the prior art outdoor luminaire 100 shown in Figure 1, often have a housing 102 located at the top of the luminaire 100 with a light source located at the bottom of the housing 102.
  • Luminaire 100 comprises a mounting 106 (also called a fitter) that can be mounted to the top of a pole (not shown in Fig. 1).
  • the light source located at the bottom of the housing 102 directs light downward from the top of the pole to a sidewalk or parking lot, for example.
  • the housing 102 is attached to the mounting 106 by one or more supports 104.
  • the housing 102 can comprise a housing top 110 and a gasket (not shown) attached to a housing base 108 by one or more fasteners so that the housing can withstand outdoor environments and in certain cases meet certain ratings such as IP66.
  • the housing 102 can contain a variety of components, such as a heat sink 112 to which the light source is attached and a power supply 116 such as a light emitting diode driver.
  • the power supply 116 can receive line voltage (e.g. 120 - 270 VAC) and convert the line voltage to a modified voltage (e.g. 10-60 VDC) that can be used by the light source. If higher line voltages are supplied to the luminaire 100, a transformer 118 can step down the higher voltage.
  • the housing 102 also contains a terminal block 114 to which a power cable supplying the line voltage is connected.
  • One challenge associated with the prior art luminaire 100 relates to connecting the wiring when installing the luminaire.
  • the power cable supplying the line voltage is routed up through the pole on which the mounting 106 is positioned, passes through a wireway in one of the supports 104, and is fed into the housing 102.
  • the housing top 110 In order to connect the power cable to the terminal block 114, the housing top 110 must be removed.
  • opening the housing top 110 is not desirable because it requires removal of several fasteners and the housing 102 contains sensitive electronic components.
  • the removal of the several fasteners to open the housing top 110 typically requires a Philips head screw driver or other specially designed tool and can be time consuming. Additionally, after opening the housing top 110 to access the components, there is a chance the housing top may not be reattached properly to the housing base 108, thereby compromising the sealed condition of the housing 102.
  • Another challenge associated with the prior art luminaire 100 relates to the surge protector that is typically coupled to the terminal block. From time to time, the surge protector may need to be replaced in connection with maintaining the luminaire. However, removing all of the fasteners to open the housing top 110 is labor intensive. Additionally, as mentioned above, opening the housing top 110 exposes sensitive electronic components and the housing top 110 may not be properly reattached by the maintenance worker.

  • any luminaire components e.g., a housing, support, or mount
  • a luminaire can be made from multiple pieces that are mechanically coupled to each other.
  • the multiple pieces can be mechanically coupled to each other using one or more of a number of coupling methods, including but not limited to epoxy, welding, fastening devices, compression fittings, mating threads, and slotted fittings.
  • One or more pieces that are mechanically coupled to each other can be coupled to each other in one or more of a number of ways, including but not limited to fixedly, hingedly, removeably, slidably, and threadably.
  • a coupling feature (including a complementary coupling feature) as described herein can allow one or more components and/or portions of an example heat sink or other component of a light fixture to become coupled, directly or indirectly, to another portion of the example heat sink or other component of a light fixture.
  • a coupling feature can include, but is not limited to, a snap, Velcro, a clamp, a portion of a hinge, an aperture, a recessed area, a protrusion, a slot, a spring clip, a tab, a detent, and mating threads.
  • a portion of a luminaire can be coupled using one or more independent devices that interact with one or more coupling features disposed on a component of the heat sink.

  • One coupling feature described herein can be the same as, or different than, one or more other coupling features described herein.
  • a complementary coupling feature also sometimes called a corresponding coupling feature as described herein can be a coupling feature that mechanically couples, directly or indirectly, with another coupling feature.
  • the outdoor luminaire comprises a housing 202, including a housing base 208 and a housing top 210 fastened together with fasteners (not shown).
  • a gasket can be positioned between the housing base 208 and the housing top 210 in order to maintain the housing 202 in a sealed condition.
  • the housing can contain components such as a light source, a heat sink, and a power supply.
  • a light source 209 such as an LED light source, can be mounted at the bottom of the housing 202 so that the light source 209 directs light downward when the luminaire is mounted on a pole.
  • the housing 202 is attached to one or more supports 204 that connect the housing 202 to a mounting 206 (also called a fitter).
  • the one or more supports 204 can be hollow to provide a wireway for routing a power cable up through the pole (not shown), through the mounting 206, through the support 204, and into the housing 202.
  • the mounting 206 of luminaire 200 is distinct in that it also comprises a terminal assembly 220 and a terminal assembly access cover 222.
  • the example terminal assembly 220 of example luminaire 200 comprises a terminal block 224, a surge protector 226,.
  • a chamber 230 is formed at least partly within the mounting 206 and comprises an aperture which is lidded by the terminal assembly cover 222, thus forming an essentially closed chamber 230.
  • the aperture renders that only the terminal assembly is accessible from the exterior, and only said aperture is lidded by the terminal assembly access cover 222.
  • the terminal assembly, in particular the terminal block 224, and the surge protector 226 are arranged in the chamber 230 which is separated from sensitive electronic components and light source.
  • the terminal assembly access cover 222 can be easily removed from the top surface of the mounting 206.
  • the terminal assembly access cover 222 can be attached, for example via a snap-fit or screw, threaded construction and removed using a slotted screwdriver or another toolless attachment mechanism.
  • a cover gasket 221 is provided, which however is optional, in between the top 223 of the mounting 206 and the terminal assembly access cover 222 to seal the connection between terminal assembly access cover 222 and the mounting 206.
  • the terminal block 224 is disposed on a mounting flange 228 that positions the terminal block 224 so that it extends at an angle through an aperture in the top surface of the mounting 206. Positioning the terminal block so that it extends partially out of the mounting 206 allows for easier access when connecting wires from the power source to the terminal block 224. Wiring from the power source is routed up through a pole (not shown) and up through the mounting 206 where wiring connections can be more easily made at the terminal block 224. Electrical connections can extend from the terminal block 224, through a wireway in a hollow space within support 204, and into the housing 202. The electrical connections from the terminal block 224, through the wireway within the support 204, and into the housing 202 are included in the manufacture of the luminaire at the factory so that the installer does not make these connections.
  • the mounting flange 228 extends into the hollow space within the mounting 206. By extending into the hollow space within the mounting 206, the mounting flange 228 prevents a top of a pole from being pushed too far into the mounting 206 where it may pinch the terminal block or the power cable.
  • the terminal assembly also comprises a surge protector 226 coupled to the terminal block 224.
  • the surge protector may need to be replaced from time to time during the life of the luminaire. Because the terminal assembly access cover 222 is more easily removed than the housing top 210, the surge protector 226 can be more easily replaced.
  • the terminal assembly 220 in the mounting 206 makes installation and maintenance of the luminaire easier and less time-consuming. For example, when installing the luminaire 200, instead of removing the several fasteners to remove the housing top 210 from the housing base 208, the terminal assembly 220 is more easily accessible at the mounting 206 and the housing 202 can remain sealed. The ability to connect the power source wiring to the terminal block 224 at a position outside the housing 202 and away from the other sensitive electrical components within the housing 202 is an additional benefit. As another example, in connection with maintaining the luminaire 200, if the surge protector coupled to the terminal block needs to be replaced, the surge protector is more easily accessed in the mounting 206 than in the housing 202.
  • FIG. 5 an alternate embodiment of the disclosure is shown.
  • the luminaire 300 of Figures 5, 6, and 7 is similar the luminaire 200 of Figures 2, 3, and 4 wherein analogous components have the same last two digits of their reference numbers in the figures. Accordingly, the description of the analogous components will not be repeated.
  • Example luminaire 300 differs from luminaire 200 in that the terminal assembly 320 is mounted and configured differently in the chamber 230.
  • terminal assembly 320 comprises a bracket 330 which is attached to the underside of a terminal assembly access cover 322.
  • the terminal assembly access cover 322 can be attached with slotted screws or another toolless mechanism to a top surface of mounting 306 thereby covering an aperture in the top surface of mounting 306.
  • the bracket 330 can have an L shape and the terminal block 324 and surge protector (not shown) can be coupled to the bracket 330.
  • the terminal assembly 320 When making wiring connections for the luminaire 300, the terminal assembly 320 can be easily detached with a slotted screwdriver or other toolless mechanism and lifted out of the mounting 306. A worker can route a power source wiring up through the pole (not shown) and up through the mounting 306 so that the power source wiring extends out from the aperture at the top surface of the mounting 306. The worker can then connect the power source wiring to the terminal block 324. Electrical connections can extend from the terminal block 324, through a wireway in a hollow space or channel within support 304, and into the housing 302. The channel being so narrow that it effectively separates the chamber from other sensitive electrical components within the housing 302.
  • the ability to connect the power source wiring to the terminal block 324 at a position outside the housing 302 and away from the other sensitive electrical components within the housing 302 is an additional benefit.
  • a worker can detach the terminal assembly 320 from the mounting 306 in the same manner just described in order to replace the surge protector. After the wiring connections are completed or the surge protector is replaced, the terminal assembly 320 can be inserted back through the aperture at the top surface of the mounting 306 and secured to the mounting 306 thereby avoiding the requirement to open the housing 302.
  • the luminaire 400 of Figures 8 and 9 is similar to the luminaire 300 of Figures 5, 6, and 7 and is similar the luminaire 200 of Figures 2, 3, and 4 wherein analogous components have the same last two digits of their reference numbers in the figures. Accordingly, the description of the analogous components will not be repeated.
  • Example luminaire 400 differs from luminaire 300 and luminaire 200 in that the terminal assembly 420 comprises a terminal assembly access cover 422 with a handle that extends upward from the terminal assembly access cover 422. Additionally, terminal assembly access cover 422 can comprise threads and complementary threads can be located at the aperture in the top surface of the mounting 406. The handle and threads allow a worker to easily rotate the terminal assembly 420 for attachment to and removal from the mounting 406. When the terminal assembly 420 is rotated and removed from the mounting 406, wiring connections to the terminal block and replacement of a surge protector can be more easily accomplished in a manner similar to that described previously in connection with example luminaire 200 or example luminaire 300.
