EQUIPMENT HOLDER FOR LIGHTING SYSTEM

Description

[0001] The present invention relates to a device holder for a lighting system.

[0002] For outdoor lighting systems in companies and municipalities, luminaires are increasingly being equipped with devices such as sensors or actuators to further adapt the lighting control of the luminaire to local conditions, for example, daylight conditions, detected movement, or presence events. To integrate devices into outdoor lighting systems, the device installation is either incorporated into the luminaire head in new product lines or externally retrofitted into existing product lines and luminaires already in operation. Retrofitting device holders in conventional lighting systems is achieved by externally attaching the device to the luminaire or pole using mounting plates, pole clamps, clamps, or screws.These mounting options vary depending on the type of luminaire and device, as well as the device orientation, and require drilling into the existing luminaire infrastructure to install fastening devices and cabling.

[0003] The resulting disadvantage of this externally mounted retrofit solution for devices is a non-standardized installation process and the resulting increased exposure of devices and cabling. Due to weather influences or the presence of animals, the likelihood of limited functionality or failure of a luminaire with a retrofitted device is increased, resulting in increased maintenance requirements. Drilling into the luminaire structure can also void the manufacturer's warranty.

[0004] WO 2019 / 092273 A1 discloses a device holder of a lighting system according to the preamble of claim 1. Further device holders in lighting systems are disclosed in US 2006 / 044789 A1 and US 6,380,909 B1.

[0005] The object of the present invention is to provide a device holder for a lighting system which can be retrofitted using a standardized procedure and yet allows individual device attachment.

[0006] The problem is solved by a device holder according to claim 1.

[0007] A special feature of the device holder according to the invention is that the device holder has a fastening unit and a pivoting arm, wherein the pivoting arm is connected to the fastening unit and the pivoting arm has a rounded shape and a platform at a flattened end onto which a device can be mounted. The device is preferably a sensor or an actuator. This design allows, on the one hand, the fastening unit to be designed uniformly and, furthermore, that the pivoting arm has a defined area for device mounting thanks to the platform. The rounded shape of the pivoting arm also promotes the runoff of rain, prevents birds from perching, inhibits the nesting of animals and reduces the accumulation of foreign objects such as snow or leaves.The external positioning of the device also prevents received or transmitted signals from having to pass through the device mount or mast. The uniform mounting method allows for quick retrofitting of the device mount, and the external mounting of different devices reduces cabling and provides increased protection against external environmental influences such as corrosion, animal nesting, rodent bites, or snow load.

[0008] According to a preferred embodiment, the fastening unit is shaped such that it represents a mast intermediate piece for a lighting mast. The fastening unit is preferably column-shaped, in particular cylindrical, or conical, and has a closed outer surface and an opening at each end. The lower end of the fastening unit is shaped as a mast receptacle, the upper end as a luminaire fastening receptacle. This offers the advantage that the device holder can be very easily retrofitted, particularly in existing mast luminaires, since the fastening unit has the same structure as the mast. The device holder therefore only needs to be inserted between the mast and the luminaire, which enables retrofitting in a defined and rapid assembly process.Furthermore, the columnar design allows the device mount to be rotated along the axis containing the device mount openings in order to align the device. For the purposes of this application, all shapes with, in particular, a circular, but also elliptical or polygonal cross-section are considered columnar and are included as preferred embodiments. The same generally applies to conical shapes. A particular advantage of a circular cross-section or a regular polygonal cross-section is that the mast adapter can be mounted on the mast in various rotational positions. This allows the device mount to be aligned at various angles along the mast's longitudinal axis.The adjustable swivel arm of the device holder allows the device to be aligned in any spatial direction, both in terms of polar angle and azimuthal angle. This allows all areas below the luminaire and even areas above the luminaire to be detected by a sensor or actuator mounted on the device holder by adjusting the position of the device holder. Furthermore, the connection between the mast mount and the mast can be secured with a locking device, such as a locking screw.

[0009] According to a preferred embodiment, the pivot arm can be pivoted in a plane perpendicular to the central longitudinal axis of the mounting unit, whereby the central longitudinal axis of the mounting unit can also be the longitudinal axis of the light pole or a light pole boom. The joint can be secured by a locking mechanism. The movable pivot arm allows the device to be aligned regardless of the position and orientation of the light pole relative to the area to be covered by the device.

[0010] According to a preferred embodiment, the supply line and / or the control line run internally in the mast adapter and can be connected to the cabling in the mast and the luminaire or luminaire head. This protects the lines, particularly from external influences, such as moisture, extreme temperatures, direct sunlight, or animals. Furthermore, the mast does not require drilling.

[0011] According to a preferred embodiment, the platform has a sealed cable entry for attaching a device. Screwing devices onto the platform allows for easy installation of different devices with different attachment points.

[0012] According to the invention, the platform for mounting a device has a connection socket with an interface. Using a connection socket with an interface allows devices to be mounted that are connected according to a standardized connection with an interface, according to the invention using an interface according to Zhaga Book 18. Implementing the standardized connection socket with an interface on the platform makes devices particularly compatible with luminaires that do not have a standardized interface in the luminaire head for devices with one of these mounting standards.

[0013] According to a preferred embodiment, the platform is provided with a provision for the insertion of an anti-theft lock. By providing a provision for the insertion of a security component, referred to here as a lock, such as a locking cylinder, theft, in particular, but also deliberate manipulation of the devices can be prevented.

[0014] According to a preferred embodiment, multiple pivot arms can be attached to one mounting unit. This allows the installation of multiple devices on multiple pivot arms, each of which can be aligned to different detection areas.

[0015] According to a preferred embodiment, the swivel arm has additional components of the mounted devices in its interior, in particular a power supply and / or a control unit. This allows for the housing of sensitive components that are part of the device module, protected from environmental influences, and also allows for efficient cabling.

[0016] According to a preferred embodiment, the platform has a water drip lip and / or a ball protection cage. By additionally applying a water drip lip, the devices mounted on the platform can be effectively protected from runoff water and freezing moisture, especially when the platform is horizontally aligned. The installation of the ball protection cage primarily serves to protect the sometimes sensitive devices in lighting fixtures located, for example, near sports fields or on play streets.

[0017] According to a preferred embodiment, the device is a precipitation sensor, an air quality sensor, a brightness sensor, a luminance sensor, a humidity sensor, a motion sensor, a presence sensor, a temperature sensor, a radio receiver, a radio transmitter, a control unit, a relay, an amplifier, and / or an antenna. The sensors can be used to detect the external environment, for example, to detect precipitation and to reduce glare for road users on wet roads by reducing the light intensity of the connected light. The devices, in particular the radio receivers or transmitters, can communicate with the light via the control lines and can be used to exchange information with other or neighboring devices or participants.The control unit can be used to process information from different sources, such as sensors or data connections, and can, for example, control the relay for switching.

[0018] According to an embodiment of the invention, a luminaire has a device holder according to claim 1 with a device, wherein the luminaire can be controlled by a control unit and the control unit receives control signals from the device attached according to the invention.
