Description

LUMINAIRE HEAD ASSEMBLY
FIELD OF INVENTION
The field of the invention relates to a luminaire head assembly comprising a frame structure, an optical block and a cover structure, and in particular a modular luminaire head assembly for outdoor luminaires.
BACKGROUND
Luminaires, in particular outdoor luminaires, are often designed for a particular purpose and/or for a specific customer, and many different luminaires have to be kept in stock for different applications.
In the commonly used outdoor luminaires, a luminaire head is usually manufactured, e.g. molded, as a single piece. Alternatively, if the luminaire head is manufactured by assembling different parts, the parts are often inconvenient to unmount from each other for the purpose of maintenance or replacement and/or the parts do not allow a high flexibility in terms of number, type, position and dimensions of internal components to be arranged in the luminaire head. Indeed. often luminaire heads are designed with a particular design which is fixed, or which can only be changed to a limited extent.
Therefore, conventional luminaire heads lack modularity, or have limited modularity. Hence, it is necessary to manufacture luminaire heads for different applications, thereby increasing the manufacturing costs. In addition, a large number of components are needed to address the needs of different customers, with a lot of different components requiring different molds.
The current problem occurring in the industry of outdoor luminaires is that when it is desirable to change the look of a luminaire head, often a metal housing part needs to be changed which is costly.
Also, when a different type of fixation is needed, often the housing needs to be changed. Further, typically the housing needs to function as a heat sink, requiring the housing to be made of a metal material.
In view of the above, the housing of a typical luminaire needs to fulfill at the same time a number of technical requirements (robustness, e.g., good vibration and thermal characteristics) as well as esthetical requirements. This typically result in a relatively heavy metal housing in which the various components of the luminaire are accommodated.
SUMMARY
The object of embodiments of the invention is to provide a modular luminaire head assembly which can fulfill the required robustness and/or vibration and/or thermal characteristics in an improved manger.
According to a first aspect, there is provided a luminaire head assembly comprising a frame structure, an optical block, a gear tray and a cover structure. The frame structure has a heat sink. The optical block has at least one light source and is attached to the frame structure opposite the heat sink. The gear tray comprises one or more electrical components such as a driver configured for driving the at least one light source and/or surge protection circuitry and/or a fuse. The cover structure is configured and arranged for covering at least a portion of the frame structure. The frame structure comprises a frame part with a frame opening extending between an upper and a lower side of the frame structure and configured to receive the gear tray.
By providing on the one hand a frame structure and on the other hand a cover structure a modular assembly is obtained, allowing to optimize the frame structure for being sufficiently rigid and robust against vibrations whilst at the same time limiting the amount of material of the frame structure.
Indeed, the frame structure can be given an improved shape so as to provide the required technical functionalities in an improved way, whilst the cover structure can be easily adapted according to the wishes of the customer and can be made in any material, without having to modify the frame structure of the luminaire head. Compared to prior art embodiments where often the housing fulfills the function of frame and cover at the same time, the assembly of embodiments of the invention can have a frame structure with a weight and/or volume which is smaller than the weight and/or volume of typical prior art housings whilst ensuring the same or even improved robustness and/or vibration characteristics (moment of inertia) and/or thermal characteristics and whilst allowing to use different materials and shapes for the cover structure so that the external view of the luminaire can be customized.
Further, by providing a frame structure, a cover structure and a gear tray which can be easily mounted in the frame structure a modular assembly allowing for easy maintenance is obtained. Indeed, when access to the gear tray is desirable, the cover structure or a portion thereof may be removed to access the gear tray, and because of the frame opening, the access can be either from above or from below the frame opening.
Preferably, the gear tray comprises a plate-like element on which the one or more electrical components are arranged. In this way the components can be easily replaced and/or new components may be added.
Preferably, the cover structure comprises an upper cover and a lower cover configured for covering the frame opening from above and from below, respectively. In this way, to get access to the gear tray, an operator may either remove the lower cover or the upper cover, e.g. depending in what is most convenient.
Preferably, an upper seal is arranged between the upper cover and the frame structure around the frame opening, and a lower seal is arranged between the lower cover and the frame structure around the frame opening. This results in a sealed compartment delimited by the upper cover, the lower cover, and a portion of the frame structure delimiting the frame opening.
Preferably, the upper cover adjoins the lower cover along at least two opposite sides of the luminaire head.
Preferably, the upper cover has a width which is larger than a width of the frame structure covered by the upper cover and which is arranged and dimensioned such that a portion of the heat sink is not covered by the upper cover and such that air is allowed to flow freely adjacent the heat sink.
Preferably, the frame structure has a fixation end configured to be fixed to a base, and the frame opening is located between the fixation end and the optical block. Preferable. the fixation end is an integral part of the frame structure.
Preferably, the frame structure comprises a first and second wing extending from the fixation end at a first and second longitudinal side of the frame opening. In this way, the frame structure can be given good robustness. Indeed, such structure can provide an improved moment of inertia and require less material than plate-like frame structures of the prior art.
Preferably, the first and second wing have a minimum height Hmin and a minimum thickness t, wherein 5 < Hmin/t < 60, preferably 6 < Hmin/t < 40, more preferably 7 < Hmin/t < 35. The inventors have discovered that such relatively thin and heigh profiles can provide the required robustness and can provide in particular improved vibration characteristics with less material as compared to prior art structures where a plate-like element is used for the frame structure. The minimum height may be e.g. between 15mm and 60mm and the thickness t may be between 1.5mm and 4mm.
In an exemplary embodiment, the first and second wing have an average height Hav and an average thickness tav, seen along a side adjacent the frame opening, wherein 5 < Hav/tav < 60, preferably 6 < Hav/tav < 40, more preferably 7 < Hav/tav < 35. The average height may be e.g. between 30mm and 60mm and the average thickness tav may be between 1.5mm and 4mm.
It is noted that in some embodiments the height may be constant across the entire length of the wing, whilst in other embodiments the height may vary, e.g., increase in the direction of the fixation end.
Also, in some embodiments the thickness may be constant across the entire length of the wing, whilst in other embodiments the thickness may vary.
In an exemplary embodiment, the frame part delimiting the frame opening may comprise a peripheral wall delimiting the frame opening. Optionally, an inner side of the peripheral wall may be provided with fixation means facilitating the mounting of the gear tray in the frame opening. Such peripheral wall may have a maximum height which is larger than 20 mm, preferably larger than 30mm, more preferably larger than 40 mm. In this way, the frame part is sufficiently rigid and provides enough room for the gear tray. Also, the relatively large height results in an improved moment of inertia.
Optionally, the frame structure may be a single piece with the heat sink being an integral part of the frame structure.
Preferably, the frame structure has a weight per unit width which, when looking from a fixation end configured to fix the frame to a base to a free end including the heat sink, first decreases at the level of the frame opening and then increases again at the level of the heat sink. In this way the weight is spatially distributed in an improved manner compared to prior art embodiments.
In another preferred embodiment, the frame structure comprises a second frame part wherein the heat sink is integrated in or coupled to the second frame part. In preferred embodiment, the second frame part is removably attached to the frame part with the frame opening.
Preferably, the cover structure is dimensioned such that air is allowed to flow freely adjacent the heat sink. For example, the cover structure may comprise an upper cover with a hole dimensioned such that a portion of the heat sink is accessible through said hole and such that air is allowed to flow freely adjacent the heat sink. In another exemplary embodiment, the cover structure may comprise an upper cover which does not cover the heat sink.
Preferably, the frame structure comprises metal, more preferably an aluminum material. The frame structure may be made entirely out of metal or may be partially in metal, e.g. an over-molded metal structure. The frame structure may also comprise carbon or a plastic thermos-conductor. In another example, the heatsink could be made in metal and the rest of the frame structure in a non-metal 5 material.
Preferably, the cover structure comprises a non-metal material, more preferably a plastic material, e.g. a recycled plastic material. However, the cover may also be made of other materials such as wood or a composite material. Also, the cover structure could be a light metal cover structure, i.e. a thin metal structure could be used for example.
According to a further aspect the luminaire head assembly comprises a frame structure, an optical block and a cover structure. The frame structure has a heat sink. The optical block is provided with at least one light source and is attached to said frame structure opposite the heat sink. The cover structure is configured and arranged for covering at least a portion of the frame structure. The cover structure comprises an upper cover with a hole dimensioned such that a portion of the heat sink is accessible through said hole and such that air is allowed to flow freely adjacent the heat sink.
By providing on the one hand a frame structure and on the other hand a cover structure a modular assembly is obtained. Indeed, the cover structure can be easily adapted according to the wishes of the customer and can be made in any material, without having to modify the frame structure of the luminaire head. Moreover, by using an upper cover with a hole, the frame structure can be adequately covered whilst still allowing a good operation of the heat sink.
According to another aspect the luminaire head assembly comprises a frame structure, an optical block and a cover structure. The frame structure has a heat sink. The optical block is provided with at least one light source and is attached to said frame structure opposite the heat sink. The cover structure is configured and arranged for covering at least a portion of the frame structure. The cover structure comprises an upper cover with a width which is larger than a width of the frame structure covered by the upper cover and which is arranged and dimensioned such that a portion of the heat sink is not covered by the upper cover and such that air is allowed to tlow freely adjacent the heat sink.
Also in such an embodiment, by providing on the one hand a frame structure and on the other hand a cover structure a modular assembly is obtained. Moreover, by using an upper cover with adequate dimensions, the frame structure can be adequately covered whilst still allowing a good operation of the heat sink.
Preferably, the cover structure comprises a lower cover configured for covering a lower portion of the frame structure, wherein the upper cover adjoins the lower cover along at least two opposite sides of the luminaire head. In this way, the upper and lower cover can adequately surround the frame structure and determine largely the look of the luminaire. Thus, the same frame structure can be combined with different cover structures if it is desirable to offer luminaire heads with a different look.
In an exemplary embodiment, the frame structure is a single piece and the heat sink is an integral part of the frame structure.
In another exemplary embodiment, the frame structure comprises a first frame part and a second frame part removably attached to the first frame part, and the heat sink is integrated in the second frame part. The upper cover may cover at least a portion of the first frame part, and preferably substantially the entire first frame part.
Preferably, the luminaire head assembly further comprises a driver configured for driving said at least one light source, said driver being attached to said frame structure, and more preferably to the first frame part thereof. For example, there may be provided a gear tray with a driver and the gear tray may be fixed to the frame structure. However, in other embodiments, the driver may be provided outside of the luminaire head.
According to a further aspect, there is provided a luminaire head assembly comprising a frame structure integrating a first fixation part, an optical block, a second fixation part, and a cover structure. The frame structure further comprising a frame part having a heat sink. The optical block comprises at least one light source and is attached to the frame structure opposite the heat sink. The second fixation part is configured to be attached to a base, such as a pole, and to cooperate with said first fixation part. The cover structure may be configured and arranged for covering at least a portion of the first fixation part and the frame part.
According to another aspect, there is provided a luminaire head assembly comprising a gear tray, a frame structure with a first fixation part, a second fixation part, and a cover structure. The gear tray comprises one or more electrical components such as a driver configured for driving said at least one light source and/or surge protection circuitry and/or a fuse. The frame structure comprises a first fixation part and a frame part configured to receive the gear tray. Preferably, the first fixation part and the frame part are integrated in one piece. The optical block comprises at least one light source and is attached to the frame structure. The second fixation part is configured to be attached to a base, such as a pole, and to cooperate with said first fixation part. The cover structure is configured and arranged for covering at least a portion of the first fixation part and the frame part.
Preferably, the first and second fixation part are configured such that the frame structure can be mounted in different positions with respect to the base. For example, the first fixation part could include a structure with a plurality of steps, wherein each step defines a different position of the frame structure relative to the second fixation part.
Preferably, the second fixation part comprises a tubular portion configured to receive a portion of a pole. In this way, the second fixation part can be easily attached to a pole, whereupon the frame structure may be fixed through the first fixation part thereof which can cooperate with the second fixation part.
Preferably, the first and second fixation part comprise a first and second pivot part, respectively, such that the frame structure can be mounted in different angular positions with respect to the base.
In this way the optical block can be oriented in a suitable direction.
Preferably, the assembly further comprises a driver configured for driving the at least one light source, said driver being attached to the frame structure between the optical block and the first fixation part. Optionally, the driver may be part of a gear tray which is attached to the frame structure, e.g. in a frame opening of the frame structure as described above.
Preferably, the cover structure comprises a lower cover configured for covering a lower portion of the first fixation part and/or an upper cover, and more preferably the upper cover adjoins the lower cover along at least two opposite sides of the luminaire head.
According to another aspect there is provided a luminaire head assembly comprising a frame structure, an optical block, a gear tray and a cover structure. The frame structure comprises a first frame part and a second frame part, said second frame part having a heat sink. The optical block has at least one light source and is attached to said frame structure opposite the heat sink. The gear tray comprises one or more electrical components, such as a driver configured for driving said at least one light source and/or surge protection circuitry and/or a fuse. The cover structure is configured and arranged for covering at least a portion of the frame structure. The gear tray is attached to the first frame part and the second frame part is pivotable with respect to the first frame part.
By having a second frame part which carries the optical block, and which is pivotable with respect tothe first frame part, the at least one light source can be oriented in a suitable manner. This may be combined with simple fixation means for fixing the first frame part to a base or with adjustable fixation means, e.g., as described above, so that two degrees of adjustment are possible.
Preferably, the cover structure comprises an upper cover configured for covering an upper portion of the first frame part and/or a lower cover configured for covering a lower portion of the first frame part. Optionally, the upper cover adjoins the lower cover along at least two opposite sides of the luminaire head.

In an exemplary embodiment, the cover structure is provided with a hole in which a receptacle configured for a receiving a pluggable external module is arranged. Such receptable may be arranged in an upper cover or in a lower cover.
The pluggable external module may contain different control blocks and/or sensors, e.g. a light sensor for sensing the light level of ambient light to automatically control the one or more light sources of the optical block. For uniformity throughout the lighting industry, electrical receptacles for receiving such external modules are mostly made according to specific standards such as standards approved by American National Standards Institute, Inc. (ANSI). Such receptacles are electrically connected to various components of the assembly, and in particular to components of the gear tray. The receptacle has a connection interface located on an external side of the cover structure, so that an external module can be plugged into the receptacle to provide control for the lighting equipment. Preferably, the receptacle and the external control module fulfil the requirements of the
ANSI C136.10-2017 standard or of the ANSI C136.41-2013 standard or of the Zhaga Interface
