Description

[0001] The present invention is directed to an enhancement module for functional enhancement of an oblong luminaire.

[0002] Oblong luminaires are well known in the lighting industry and are commercially available for a variety of applications. Especially for the lighting of interior areas a number of respective luminaire models is available. For industrial or commercial areas the use of cost efficiently designed luminaires is common. These luminaires are usually provided with a basic functionality, lacking the possibility to adapt the light emission to various needs, which might arise when the dedication of space is changed.

[0003] In this case, exchanging respective luminaires or enhancing their functionality is usually unavoidable. Hence substantial efforts are required mounting to significant costs.

[0004] Exchanging luminaires with an improved model requires a significant time and is usually obviated wherever possible. Further, adapting luminaires to a changed application is likewise tedious, in many cases owed to the fact that solutions to improve the functionality require sophisticated fitting of additional devices, i.e. special ballasts, to a luminaire or the proximity thereof, resulting in a complex installation process. Moreover the enhancement of a certain luminaire model might be inconceivable, since the assembly might not provide the opportunity to incorporate necessary devices, frequently due to safety and security reasons. In most cases these constrains apply to small or oblong luminaires.

[0005] Accordingly, it is an object of the present invention to improve the possibility to enhance the operational functions of an oblong luminaire, especially raising the opportunity to adapt an oblong luminaire to a variety of applications.

[0006] This object is solved by an enhancement module for an oblong luminaire according to claim 1. Advantageous modifications of the present invention are subject matter of the depending claims.

Preferably adding remote controllable functionality, adding functionality of an emergency luminaire and modifying the light distribution is realized benefiting from the enhancement module.

[0009] Advantageously the enhancement module is combined to the oblong luminaire, with major faces - preferably three or more faces - of the respective enhancement module housing remaining accessible after installation, implying that major elements of the enhancement module preferably the controller means are arranged beyond the space enclosed by the housing of the oblong luminaire according to its original design. For certain applications it is favorable that the enhancement module comprises a ballast, preferably also arranged beyond said space.

[0010] The inventive enhancement module is provided also with the benefit of creating the possibility for small or narrow luminaire assemblies to enhance their functionality. Advantageously the oblong luminaire imposes a base element for a readily achievable fitting of the enhancement module - as sketched above with major elements beyond the base element.

[0011] In an advanced embodiment of the enhancement module, the housing is formed to complete the end face of the housing of the oblong luminaire form-fittingly. Advantageously the other faces of the enhancement module remain accessible when fitted to the luminaire. Combining form-fittingly with the oblong luminaire the enhancement module can be regarded as a continuation in shape, favorably improving the optical appearance of the luminaire and enhancement module combination. Further a number of benefits for the combination process of oblong luminaire and enhancement module arise.

[0012] Preferably the enhancement module completes an end face of the oblong luminaire entirely. Especially the possibility to combine the enhancement module electrically with the oblong luminaire is aided. Respective end faces of the oblong luminaire can be arranged to be protruded or removed without corrupting the appearance of the luminaire. Moreover, as the luminaire serves as a base element to combine with the enhancement module, sufficient stability is provided to facilitate the fitting to the oblong luminaire.

[0013] Further facilitating the combination of enhancement module and oblong luminaire, the enhancement module comprises accommodation means, formed to combine with a lamp holder.

[0014] Preferably when using two enhancement modules at both ends of the oblong luminaire, it is conceivable to add a modified lamp holder providing the possibility to optimize the usage of illumination means. Cost efficient oblong luminaires preferably comprise a tubular fluorescent lamp. For certain applications, advantageously for the sake of energy saving purposes, it might be favorable to replace the respective lamp with LED lighting means. Accordingly, the enhancement module might be formed to add a lamp holder expedient to operate LED lighting means. A respective lamp holder might also be comprised in the enhancement module.

Preferably the accommodation means are arranged to fit the respective lamp holder to an operating position stipulated by the original design of the oblong luminaire. Substantial advantages in combining the enhancement module electrically are achieved likewise.

[0016] In this modification of the invention, the exchange of ballasts originally comprised in the oblong luminaire can be obviated in most cases, providing a cost efficient solution for an enhancement of operational functions. Further, advantageously the wiring to the lamp holder is routed through the enhancement module creating the possibility to interfere electrically with the lighting means.

[0017] Moreover, to foster the electrical combination with the luminaire, the enhancement module comprises electrical connection means, formed to combine with the wiring or electrical connection means of the oblong luminaire.

Advantageously the accommodation means are provided with slots, in an example accommodating respective sliding means form fittingly.

[0020] Moreover, to improve the enhancement possibilities the enhancement module comprises attachment means to combine with the oblong luminaire. In an embodiment the attachment means are represented by an oblong extension plate, preferably arranged to combine with a housing member of the oblong luminaire. However, other attachment means are also conceivable, for example the attachment means might be formed to be imposed on the narrow end face of the luminaire, preferably gliding, more preferably clamping. Further, in an embodiment, the attachment means might be arranged to accommodate luminaire members, advantageously in a clamping or gliding manner.

[0021] In a preferred embodiment the attachment means comprise snap-fitting or latching means to combine the enhancement module with the oblong luminaire in a reliable and safe manner. Preferably the snap fitting or latching combination is not detachable from the exterior of the luminaire and respectively the enhancement module is formed to avoid unintended modifications to the illumination system.

[0022] With adding the enhancement module to the luminaire, the possibility emerges to arrange a number of possible enhancements in a swift and efficient manner. Preferably the enhancement module is arranged to control operational functions of the oblong luminaire, based on control signals generated and subsequently processed by the enhancement module.

[0023] Further, synergetically taking benefit of additional accessible housing faces provided by the enhancement module, the enhancement module preferably comprises sensor means to detect the presence of a person. Also the detection of motion of objects in the proximity of the enhancement module, aided by respective sensor means is conceivable.

[0024] Advantageously the sensor means generate a control signal, and preferably the controller means are arranged to initiate the lighting of the oblong luminaire when presence or motion is detected.

[0025] In a modified embodiment of the invention the enhancement module comprises sensor means to detect the ambient brightness, advantageously generating a control signal. In an example the controller means are arranged to omit the lighting of the oblong luminaire when ambient brightness exceeds a predefined threshold level. Moreover, the threshold level might be adjustable to adapt to various environments. Further, it is also conceivable that the oblong luminaire is automatically lit, when ambient brightness is below a threshold level.

[0026] Preferably the operational functionality of the oblong luminaire can be enhanced to the demands of an emergency luminaire, benefiting from functions provided by the enhancement module. Advantageously the enhancement module is formed to detect the loss of power supply for the oblong luminaire, preferably generating a corresponding control signal.

[0027] The controller for example is formed to exhibit and control emergency functionality of a luminaire. In a favorable embodiment, the controller is arranged to light the luminaire subsequent to the detection of power supply loss, to provide a basic illumination. In an advanced embodiment, the control signal of the motion or presence sensor means can be taken into account.

[0028] In a preferred modification of the invention, the controller is formed to connect the oblong luminaire to an emergency power supply, for example when the loss of power supply is detected. Advantageously the emergency power supply is comprised in the enhancement module, preferably formed of an accumulator or battery assembly, in an example arranged to be charged by the power supply of the respective oblong luminaire. However, other emergency power supply sources integral to the enhancement module or oblong luminaire are also conceivable, for example a capacitor arrangement.

[0029] Advantageously the enhancement module is formed to dim the intensity of light emitted by the oblong luminaire, preferably realized by the controller means. This proves especially efficient for energy saving purposes. Accordingly a variety of assemblies preferably comprising aforementioned modifications are conceivable. For example an enhancement module arranged for emergency lighting purposes can be formed to dim the light emission of the respective luminaire. Moreover, based on control signals of motion or presence sensor means, a dimming can be can be favorable for certain applications.

[0030] Further, also fostering the reduction of energy consumption, the enhancement module is formed to alter the number of light sources used for illumination. Preferably this can be realized by the controller means. For example the number of light sources used for emergency lighting can vary to the normal operation of the luminaire.

[0031] In a preferred modification of the invention the enhancement module comprises light sources, formed to illuminate an area in the proximity of the enhancement module. It is also conceivable that the additional light sources comprised in the enhancement module favorably contribute to the overall light emission of the luminaire, preferably highlighting special spots or obstacles.

[0032] Advantageously the enhancement module comprises a microprocessor, arranged to control operational functionality of the oblong luminaire. Preferably the microprocessor is formed to initiate and control a sequence of lighting functions of the oblong luminaire, according to a predefined sequence stipulated by a set of instructions and data processible by the microprocessor.

[0033] As an example, the predefined sequence might comprise a dimming sequence, mimicing the course of natural light.

The method comprises the step of combining an enhancement module electrically with the oblong luminaire, and subsequently another step of combining the enhancement module with a narrow end face of the oblong luminaire. Inventively the enhancement module comprises a housing formed to combine with the oblong luminaire, and further controller means arranged to control operational functions of the oblong luminaire.

[0035] In an advantageous modification of the method the enhancement module is combined to the oblong luminaire while the oblong luminaire remains installed.

[0036] Preferably the method is facilitated by an oblong luminaire provided with a removable end cap. In this case the method can be modified to removing the removable end cap, favorably providing an aperture in the housing of the oblong luminaire, combining the enhancement module electrically with the oblong luminaire, and further combining the enhancement module with a narrow end face of the oblong luminaire, completing the margin provided by the removal of the end cap form fittingly.

[0037] Another aspect of the invention is directed to a luminaire arrangement with an oblong luminaire and a removable enhancement module, arranged at the narrow end face of the oblong luminaire. The enhancement module comprises a housing, formed to combine with the narrow end face of the oblong luminaire, and controller means, arranged to control operational functions of the oblong luminaire.

[0039] Owners of commercial environments frequently face the task to change the dedication of facilities to adapt to varying demands. In many cases this brings along the need to reroute pathways etc., thus in order to meet the requirements of lighting standards a modification of the lighting system is usually unavoidable. For example a less frequently used pathway might become an emergency route, necessitating a number of luminaires to fulfill emergency lighting requirements. Other cases of adaptation are also conceivable, and the inventive enhancement module is formed to aid these adaptations.

[0040] Figure 1 shows an oblong luminaire 10 as it might be installed in the aforementioned emergency pathway and furthermore an embodiment of an enhancement module 100 for functional enhancement of an oblong luminaire 10 according to the invention. As can be seen, the enhancement module 100 comprises a housing 110, formed to combine with the narrow end face of the oblong luminaire 10. Moreover, not visible in the embodiment of Figure 1 the enhancement module 100 according to the invention comprises controller means arranged to control operational functions of the oblong luminaire 10.

[0041] Following the example sketched above, the enhancement module 100 might be formed to enhance the functionality of an oblong luminaire 10 according to emergency lighting standards.

[0042] Providing a variety of benefits the enhancement module 100 is advantageously formed to complete the narrow end face of the housing 110 of the luminaire form fittingly. Figure 1 shows an oblong luminaire 10 comprising a readily removable end cap at the narrow end. The housing is formed to replace the end cap, completing the narrow end face of the luminaire form fittingly and entirely.

The slots are provided in a bay, forming accommodation faces for the lamp holder 14, fostering a form-fitting combination of enhancement module 100 and lamp holder 14. Advantageously the slots are arranged to combine form fittingly with accommodation means comprised in the lamp holder 14. Lamp holder 14 comprises projections with an end face exceeding the dimensions of the slots, thus the projections can be slid into the slots form fittingly, providing a frictional combination of lamp holder 14 and housing 110.

[0045] In the example lamp holder 14 favorably comprises electrical connection means and a socket to combine with a lamp - in the depicted case a tubular fluorescent lamp. According to the invention the combination to a lamp holder 14 for any other type of lamp is not excluded. For example the usage of gas discharge lamps, LEDs - in particular LED arrays - or electric bulbs is conceivable. Preferably, the enhancement module 100 comprises corresponding connection means 145 to combine with the connection means of the lamp holder 14. Advantageously the connection means 145 might also be formed to combine to electrical connection means or the wiring comprised in the oblong luminaire 10.

For example an expedient connector might be mounted or formed integrally to the oblong extension plate, completing electrical connection of oblong luminiare 10 and enhancement module 100, by latching the extension plate at an operating position.

[0049] In order to adapt to a variety of applications the enhancement module 100 according to the invention is provided with controller means. Preferably the enhancement module is arranged to control operational functions of the oblong luminaire 10, based on control signals generated and subsequently processed by the enhancement module.

A suitable connector might be provided, preferably in the enhancement module 100. But also the oblong luminaire 10 might be arranged to support the routing of signals between two enhancement modules 100 or the enhancement module 100 and luminaire members. Embodiment of Figure 4 shows connection means 145, provided with three poles, wherein one pole carries a control signal of sensor means 115, other poles refer to power supply in this example.

[0051] Even for the sketched case of an enhancement module 100 formed to add functionality of an emergency luminaire to the oblong luminaire 10, it is advantageous that the enhancement module 100 comprises sensor means 115 to detect the presence of persons. Preferably the respective sensor means 115 comprise an infrared receiver, advantageously formed to evaluate a differential signal, taken at different points in time or space. In an advanced embodiment a camera can be comprised.

[0052] Based on a control signal of the sensor means 115 the lighting of the oblong luminaire 10 can be controlled. In the case of an emergency luminaire this can be used to improve the duration of illumination by avoiding unnecessary constant lighting of the luminaire.

[0053] Further, a similar result can be gained by advantageously proposing sensor means 115 comprised in the enhancement module 100, arranged to detect the motion of objects in proximity of the enhancement module. In general identical sensor means 115 as for the detection of presence of persons are conceivable. A modified embodiment, might comprise a photoelectric barrier, a light beam or the like to support the detection of motion.

[0054] In an advanced embodiment, the enhancement module 100 comprises sensor means 115 arranged to detect and measure ambient brightness. In an example the respective sensor means 115 can be represented by a photodiode comprising a signal corresponding to the level of ambient illumination. Preferably the sensor means 115 are arranged at a position obviating the detection of light emitted by the oblong the luminaire 10. In an example, an expedient arrangement could be at an elevated position beyond the path of light emission of the luminaire. Further a differential analysis of at least two sensor elements might be beneficial.

[0060] Further in an advantageous embodiment, the enhancement module 100 can be arranged to monitor the current provided for respective light sources, thus raising the possibility to conclude on functionality of the light sources or their respective aging processes. Preferably the enhancement module is formed to signal or indicate light sources, not meeting a predefined current consumption interval. Preferably the enhancement module 100 is arranged to adapt the signaling and especially the respective current interval of proper operation to various light sources, possibly also individually for a plurality of light sources.

[0061] In a preferred embodiment the enhancement module 100 is formed to dim the intensity of light emitted by the oblong luminaire 10. Following the sketched example of an enhancement for an emergency luminaire, the enhancement module is preferably formed to operate the light source of the oblong luminaire with reduced power consumption when compared to normal operation, thus enhancing the duration of emergency illumination.

[0062] However, it is also conceivable to provide dimming functionality for general illumination purposes, to adapt to various needs.

[0063] Moreover, in an example, the enhancement module 100 might be formed to alter the number of light sources used for illumination.

[0064] Preferably the enhancement module 100 comprises additional light sources, favorably contributing to the light emission of the oblong luminaire 10. Preferably the opportunity is raised to highlight obstacles or projecting spots. Advantageously the additional light sources are formed as LED light sources, preferably supporting the usage as an emergency luminaire.

[0065] In a preferred embodiment the enhancement module 100 comprises a microprocessor arranged to control functionality of the oblong luminaire 10. Advantageously the microprocessor is formed to initiate and control a sequence of lighting functions of the oblong luminaire 10 according to a predefined sequence, defined by a set of instructions or data processible by the microprocessor.

[0066] As an example, the predefined sequence might comprise a dimming sequence mimicing the course of natural light.

[0067] Furthermore, it is also conceivable that the predefined sequence controls switching events, to illuminate the oblong luminaire 10 for a certain period or at certain points in time, including blinking or flickering effects, advantageously used for signaling purposes.

[0068] Moreover, the predefined sequence might include the monitoring of battery voltage, and comprise the signaling of insufficient battery power, of an emergency power supply for example.

[0071] Advantageously a lamp holder 14 can be combined with the enhancement module 100, preferably before combining the enhancement module 100 with the oblong luminaire 10.

[0072] Further, in a modification the lamp holder 14 is previously combined to the oblong luminaire 10. Therefore, a step to enhance the functionality of an oblong luminaire comprises removing the lamp holder 14 from the oblong luminaire 10 and combining it with the enhancement module 100.

[0073] Advantageously the mounting of the enhancement module 100 can be arranged while the oblong luminaire 10 remains installed.

Figure 1 shows an end cap 16 snapped or slid on a U-shaped housing member 12 comprised in the oblong luminaire 10. Removing this end cap creates an aperture, providing access to both electrical and mechanical connection means comprised in the oblong luminaire 10. Mechanical connection means are realized by the U-shaped housing member 12, as an example. Electrical connection means can comprise connectors formed to restrict the electrical connection to a defined polarity. Preferably the enhancement module 100 comprises expedient connection means 145, arranged with a likewise restriction.

Moreover the oblong extension plate is formed to lock snap-fittingly with the oblong luminaire 10. The extension plate is advantageously provided with projections, formed to protrude openings comprised in the guiding means, latching at predefined positions.

[0077] Therefore, a modified method comprises combining the enhancement module 100 mechanically with a narrow end face of the oblong luminaire 10 and completing the margin provided by the removal of the end cap 16 form fittingly.
