Description

FIELD OF INVENTION

The field of the invention relates to luminaires, in particular outdoor luminaires, comprising a support pole and a luminaire head. Particular embodiments relate to the field of luminaires having a luminaire head arranged vertically above the support pole, and more in particular to so-called lanterns.

BACKGROUND

Outdoor luminaires in the form of lanterns are known. In some prior art modules the light sources, the driver for the light sources and other functionalities are arranged in or on a top compartment integrated with a cap of the luminaire head. Such solutions have the disadvantage that the cap becomes relatively large and that power has to be provided to the cap.
In other existing solutions the light sources are arranged in or on a cap of the luminaire head, and the driver of the light sources is arranged in a bottom part of the luminaire head. Such solutions have the advantage that the driver can be easily connected to a power cable in the support pole but have the disadvantage that the driver is usually difficult to remove for maintenance.
EP 2 706 285 A1 discloses a lantern comprising a base, a luminaire part with a conical jacket, and a cover above the luminaire part. A detachable housing for LED lights is mounted on the side of the cover facing the luminaire part. The interior of the base is provided with a support frame for receiving a power supply unit. The support frame is formed with guide rails along which the power supply unit is inserted into the base. When inserted into the base, the power supply unit is connected to a power line. The interior of the luminaire part is penetrated from bottom to top by a tube in which the power line leading to the LED lights is located.
US 2009/147521 A1 discloses an LED lamp including a housing having a base, a frame at a top end of the housing and a plurality of stanchions interconnecting the base and the frame. A heat sink is mounted on the frame. An LED module is received in the housing and attached on a bottom surface of the heat sink. A PCB is arranged on the base of the housing, and a reflector is located on the PCB. A transparent envelope is received in the housing and covers windows defined between the stanchions. A light generated by the LED module is reflected by the reflector to transmit outwardly through the envelope to illuminate a surrounding environment.
DE 11 87 731 B discloses a mast-top luminaire with fluorescent lamps, in which the lamp holders for the fluorescent lamps and the associated ballasts and capacitors are mounted on an upwardly removable mounting frame. The mounting frame is provided with a center support tube placed on a stanchion at the base of the luminaire, which projects only partially into the support tube. The light roof is fixed to a support rod guided and displaceable in the remaining part of the support tube. The light roof can be completely removed by pulling up, or can be fixed at a certain altitude by means of the locking device. The light roof is screwed to the support tube by means of a thread.

SUMMARY

The object of embodiments of the invention is to provide a luminaire of the type stated in the preamble, allowing for a fast and simple mounting and an easy maintenance whilst at the same time being robust.
According to the invention there is provided a luminaire comprising a support pole and a luminaire head arranged vertically above the support pole. The luminaire head comprises a base module, an at least partially transparent or translucent casing, a removable cap, and a support with a plurality of light sources. The base module is fixed to the support pole and provided with an open top. The electronic gear unit is arranged in or on the base module and comprises one or more electronic components. The casing has an open top and an open bottom, and extends upwardly from the base module. The casing and the base module are designed such that the electronic gear unit is removable from the base module through said casing. The removable cap closes the open top opening of the casing. The support is provided with a plurality of light sources arranged to emit light through the casing and connected to one or more electronic components of the electronic gear unit. The luminaire comprises at least one rod, preferably at least one hollow rod, extending, preferably vertically, from the base module to the open top of the casing. The at least one rod is arranged in at least one correspondingly shaped channel in the base module, and the casing extends around the at least one rod. The at least one rod comprises a guiding element, and the electronic gear unit is provided with a receiving element for receiving the guiding element, such that the at least one rod plays a guiding role for the electronic gear unit toward the base module.
By having a removable cap, by arranging the electronic gear unit in or on the base module, and by designing the casing and the base module such that the electronic gear unit is removable from the base module through said casing, the electronic gear unit can be easily removed for maintenance. Further, since the electronic gear unit is arranged in the base module it can be easily connected to the power cable passing through the support pole. Since the cap does not have to carry the one or more electronic components mounted in the electronic gear unit, the cap can be relatively compact and light, resulting in a compact and light luminaire head.
According to an exemplary embodiment, the luminaire comprises at least one cable duct extending, preferably vertically, from the base module to the open top of the casing, wherein at least one cable passes through the cable duct for connecting one or more electronic components of the electronic gear unit with the plurality of light sources. For example, the above-mentioned at least one hollow rod may correspond to the at least one cable duct. Preferably, the one or more cable ducts are arranged near an inner surface of the casing so that they do not hinder the movement of the electronic gear unit through the casing when removing the electronic gear unit.
In other embodiments, the above-mentioned at least one rod, preferably at least one hollow rod, extends, preferably vertically, from the base module to the open top of the casing for other purposes, such as increasing the robustness of the luminaire, providing a receiving means for receiving fixations means for fixing the cap, etc. Preferably, the one or more rods are arranged near an inner surface of the casing so that they do not hinder the movement of the electronic gear unit through the casing when removing the electronic gear unit.
In a particular embodiment, the guiding element extends from the base module, along the at least one rod, towards the cap.
Preferably, the luminaire further comprises a heat sink configured to remove heat from the support. The heat sink is arranged in contact with the support. The heat sink may be an integral part of one of the other components, e.g. of the cap or of the base module.
According to an exemplary embodiment the support with the plurality of light sources is arranged on and/or integrated with the cap. In that manner, when an operator removes the cap, he has access to the casing and can easily remove the gear unit by lifting it from the base module, through the casing out of the luminaire. Also, the cap itself can function as at least a portion of the heat sink, thus functioning both as a closure means as well as a heat transfer means. Optionally an additional heat sink part may be arranged between the support and the cap.
Preferably, the support is a PCB, and the plurality of light sources comprises a plurality of light emitting diodes.
According to an exemplary embodiment the electronic gear unit is provided with a handle which is accessible through the casing, at an upper part of the electronic gear unit. Such a handle will allow the operator to easily grab and remove the electronic gear unit from the luminaire through the casing.
Preferably, the electronic gear unit comprises a driver configured for driving the plurality of light sources, for example a LED driver if the plurality of light sources comprises light emitting diodes, and the plurality of light sources is connected to the driver. The same driver may be used to drive one or more other electronic components, such as a controller. Alternatively one or more further drivers may be added to drive one or more other electronic components.
According to an exemplary embodiment the base module comprises a compartment with an open top for receiving the electronic gear unit. In that manner the electronic gear unit can be mounted within the base module and is not visible through the casing when a person below the luminaire looks upward at the luminaire. Further the compartment may have a guiding function, resulting in an improved positioning of the electronic gear unit within the luminaire.
According to an exemplary embodiment the compartment of the base module has a circumferential wall section, preferably a substantially cylindrical wall section, which is provided at an inner side thereof with a guide element, and the electronic gear unit is provided with a receiving element for receiving the guide element, such that the electronic gear unit can be aligned in the base module ensuring a correct positioning thereof. The substantially cylindrical wall section may have a diameter between 150 and 350 mm.
According to an exemplary embodiment the base module is provided with a socket connected to an electrical cable in the support pole, and the electronic gear unit is provided with electrical pins fitting in the socket. Alternatively, the base module is provided with electrical pins connected to an electrical cable in the support pole, and the electronic gear unit is provided with a socket for receiving the electrical pins. In that manner, the electrical connection of the electronic gear unit to a power supply can be realised by simply arranging the electrical pins in the socket when placing the electronic gear unit in or on the base module. The electrical connection means, i.e., the pin-socket combination, further allows a mechanical fixation of the gear unit to the base module.
According to an exemplary embodiment the casing comprises a substantially cylindrical section. Alternatively, the casing may comprise a substantially conical section. The cylindrical or conical section may be entirely transparent or translucent. The casing may further comprise an upper connector section attached to a top end of the cylindrical or conical section. The upper connector section may be provided with attachment means configured for cooperating with matching attachment means of the cap such that the cap can be removably attached to the upper connector section. Preferably, the attachment means are configured to allow a tool-less removal of the cap.
The cylindrical or conical section may be made e.g. from a transparent or translucent polycarbonate material or glass, and may have a length between 300 mm and 700 mm and a diameter between 150 and 350 mm.
According to an exemplary embodiment the cap is connected with a safety cable to the casing such that upon removing the cap it can remain pending whilst removing or introducing the electronic gear unit.
According to an exemplary embodiment the one or more electronic components comprise at least one of a driver, a dimmer, a controller, a surge protection device, an electrical connector means.
Preferably, the plurality of light sources is arranged on the support in a plurality of rows, wherein each row comprises one or more light sources. Further, each light source may be provided with an optical element such as a lens element. Preferably, one or more optical element plates, such as one or more lens plates are provided, wherein each optical element plate comprises a plurality of optical elements to cooperate with a corresponding plurality of light sources. Optionally the luminaire may comprise further light guiding or light modifying elements, such as one or more reflector elements or one or more diffusor elements or one or more coloured elements, to guide and/or modify light from the light sources through the casing.
According to an exemplary embodiment, the optical element comprises a lens element associated with the light sources. Indeed, lens elements may be typically encountered in outdoor luminaire systems, although other types of optical elements may be additionally or alternatively present in such luminaires systems, such as reflectors, backlights, prisms, collimators, diffusors, and the like. In the context of the invention, a lens element may include any transmissive optical element that focuses or disperses light by means of refraction. It may also include any one of the following: a reflective portion, a backlight portion, a prismatic portion, a collimator portion, a diffusor portion. For example, a lens element may have a lens portion with a concave or convex surface facing a light source, or more generally a lens portion with a flat or curved surface facing the light source, and optionally a collimator portion integrally formed with said lens portion, said collimator portion being configured for collimating light transmitted through said lens portion. Also, a lens element may be provided with a reflective portion or surface or with a diffusive portion.
According to an exemplary embodiment, the luminaire further comprises a ring-shaped hat forming a ring-shaped disc protruding outwardly at an upper end of the casing. Such a ring-shaped disc functions as a reflector reflecting light which leaves the casing in an upward direction, in order to redirect the light downwardly. Such a ring-shaped disc may be a separate component arranged between the casing and the cap, or may be an integral part of the cap, or may be an integral part of the casing, e.g. an integral part of the connector section of the casing.
According to another exemplary embodiment the support with the plurality of light sources is arranged in or on the electronic gear unit, on the base module, i.e. at or near the bottom of the casing. The cap may then be provided with a reflector configured to reflect light from the plurality of light sources through the casing. The reflector may have a curved reflective surface, e.g. a curved surface with a central portion protruding downwardly into the casing. The curved surface may be substantially conical with a slightly curved cross section, and with an apex located in the center of the cap and pointing into the casing. The shape of the curved surface may be adapted as a function of the desired light distribution of the luminaire.

Figures 7A and 7B illustrate another exemplary embodiment of a luminaire head which further comprises a ring-shaped hat 700 forming a ring-shaped disc protruding outwardly at an upper end of the casing 200. Such a ring-shaped disc functions as a reflector reflecting light which leaves the casing 200 in an upward direction, in order to redirect the light downwardly. Such a ring-shaped disc 200 may be a separate component arranged between the casing 200 and the cap 300, or may be an integral part of the cap 300, or may be an integral part of the casing 200, e.g. an integral part of the connector section 220 of the casing 200.
According to another exemplary embodiment which is illustrated in figure 8, the support 500 with the plurality of light sources 510 is arranged in or on the electronic gear unit 400 which is arranged in or on the base module 100, i.e. at or near the bottom of the casing 200. In the illustrated embodiment the casing 200 comprises a transparent or translucent substantially cylindrical section. The cap 300 may then be provided with a reflector 540 configured to reflect light from the plurality of light sources 510 through the casing 200. In figure 8 the various components of the luminaire head H are shown very schematically but the skilled person understands that they may be provided with the same or similar features as described above for other embodiments. For example, gear unit 400 may be provided with a handle, preferably arranged next to the support 500 such that the handle does not hinder the light emitted by the light sources 510. In this embodiment the heat sink 600 may be integrated with the frame of the electronic gear unit 400, and the heat sink 600 may be arranged such that it is in contact with the base module 100 to transfer heat out of the luminaire head H.
According to yet another exemplary embodiment which is illustrated in figure 9, the support 500 with the plurality of light sources 510 is arranged in or on the electronic gear unit 400 which is arranged in or on the base module 100, i.e. at or near the bottom of the casing 200. In the illustrated embodiment the casing 200 comprises a transparent or translucent substantially conical section. The cap 300 may then be provided with a reflector 540' configured to reflect light from the plurality of light sources 510 through the casing 200. The reflector 540' may comprise a curved surface which is substantially conical with a slightly curved cross section 541', and with an apex 542' located in the center of the cap 300 and pointing into the casing 200, as illustrated in figure 9. The shape of the curved surface may be adapted as a function of the desired light distribution of the luminaire.
As in figure 8, in figure 9 the various components of the luminaire head H are shown very schematically but the skilled person understands that they may be provided with the same or similar features as described above for other embodiments. For example, the gear unit 400 may be provided with a handle, preferably arranged next to the support 500 such that the handle does not hinder the light emitted by the light sources 510. Also in this embodiment the heat sink 600 may be integrated with the frame of the electronic gear unit 400, and the heat sink 600 may be arranged such that it is in contact with the base module 100 to transfer heat out of the luminaire head H.
Although not shown in figure 9, in this embodiment the luminaire comprises at least one rod, preferably at least one hollow rod, extending from the base module 100 to the open top of the casing 200. The at least one rod may not necessarily be vertical, and may follow the substantially conical section of the casing 200. Further, the at least one rod may be arranged in at least one correspondingly shaped channel (not shown in figure 9) in the base module 100, and the casing 200 may extend around the at least one rod.
In the illustrated embodiments of the figures, by having a removable cap 300, by arranging the electronic gear unit 400 in or on the base module 100, and by designing the casing 200 and the base module 100 such that the electronic gear unit 400 is removable from the base module 100 through said casing 200, an operator can easily remove the electronic gear unit 400 for maintenance. Indeed, an operator can remove the cap 300, preferably in a tool-less manner thanks to suitable attachments means between the cap 300 and the casing 200, wherein the cap may be hanging next to the casing thanks to the safety cable 310. Next, the operator can remove the electronic gear unit 400 through the casing 200, wherein the electrical disconnecting is preferably done in an easy manner thanks to a socket/pin disconnection. Further, since the cap 300 does not have to carry the one or more electronic components 401, 402, etc. mounted in the electronic gear unit 400, the cap 300 can be relatively compact and light, resulting in a compact and light luminaire head H.
