Description
Description Adapter for a light source and at least one alternative luminous means Technical field The invention relates to an adapter for a light source and at least one alternative luminous means and to an illumination arrangement with such an adapter and a luminous means mount having the alternative luminous means.
Prior art WO 02/062106 Al has disclosed a lamp arrangement with a compact fluorescent lamp with a base at one end for producing main illumination and with a light-emitting diode arrangement for producing alternative illumination, in the case of which the light-emitting diodes are arranged in an annular space between the discharge vessel of the compact fluorescent lamp and an envelope on the base. This lamp arrangement provides control electronics, via which the lamp arrangement can be operated in the main illumination mode, the alternative illumination mode or in both illumination modes simultaneously as a function of an actuation sequence of a wall switch.
One disadvantage with such lamp arrangements is the fact that the heat-sensitive light-emitting diodes are arranged in a region which is subjected to high thermal loads of electrode filaments which are arranged in end sections of the discharge tubes and are heated so as to produce free electrons. As a result of the thermal loading of the light-emitting diodes, the light emission decreases as the temperature of the discharge tubes increases. Furthermore, the thermal loading results in a reduced life of the light-emitting diodes and, once the maximum operating temperature has been reached, in their failure. The thermal loading of the light-emitting diodes is further intensified by an envelope used in the prior art in accordance with WO 02/062106 Al as a result of the reduced heat emission of the lamp arrangement and the thereby increasing internal temperature of the envelope.
Yet even when the light-emitting diodes are arranged in a region of the discharge tubes with low thermal loading there is still the disadvantage that, as a result of the rigid fixing of the light-emitting diodes on the lamp arrangement, the direction of light of the light-emitting diodes and the type of light-emitting diodes in the lamp arrangement cannot be altered. Furthermore, in the event of failure of the compact fluorescent lamp, the light-emitting diodes need to be replaced together with the fluorescent lamp.
As a result of the combined arrangement of the compact fluorescent lamp and the light-emitting diodes, it is not possible to use conventional light sources, such as general-service incandescent lamps (GLS lamps), halogen incandescent lamps or compact fluorescent lamps, for example.
Description of the invention The invention is based on the object of providing a lamp arrangement with at least one light source for producing main illumination and with at least one alternative light source, in particular a light-emitting diode arrangement, for producing alternative illumination, which lamp arrangement makes improved light emission of the light-emitting diode arrangement possible in desired directions with an extended life, significantly broader use possibilities and low costs in comparison with conventional solutions.
This object is achieved according to the invention by an adapter as claimed in claim 1 and an illumination arrangement as claimed in claim 9. Particularly advantageous embodiments of the invention are described in the dependent claims.
The adapter according to the invention for a light source and at least one alternative luminous means has a base for the supply of current, a lampholder for electrically connecting the light source and the base and at least two electrical contacts for the supply of voltage to the alternative luminous means.
This configuration means that standard light sources, such as lamps with a base at one end, for example, such as GLS lamps, high-volt halogen lamps or DULUX-EL lamps, can be used without any structural intervention in the standard light source itself with LED illumination together in lampholders known from the prior art. Therefore only the adapter is required as the additional component part.
Preferably, the adapter has a substantially cylindrical housing, with the result that there is no significant optical disruption of the overall impression if at least partially rotationally symmetrical light sources, such as incandescent lamps, for example, are used.
The base and the lampholder are preferably arranged opposite one another on the adapter. This allows for the conventional lampholder, adapter and incandescent lamp to be arranged one behind the other, in which arrangement the illumination of a space with the incandescent lamp changes only slightly in comparison with the incandescent lamp being screwed directly into the conventional lampholder.
It is advantageous if the light source is operated on the system voltage in order to achieve a high luminance when using the light source. In contrast to the illumination by means of the alternative luminous means, which can be used in the form of an LED arrangement for producing a mood or for orientation purposes or for defined task lighting with low energy, desired general lighting can thus be provided.
As a result of the widespread availability of the bases such as E27, E14, B22d, for example, general-service incandescent lamps, halogen incandescent lamps or compact fluorescent lamps are preferably used as the light sources.
It is preferable to use a light-emitting diode arrangement as the alternative luminous means. The light from the light-emitting diodes is suitable for producing moods or for orientation purposes as a result of the luminous flux which is at present still low. However, it is also possible for them to be used as directed task lighting. In this case, an optical assembly with the function of scattering or focusing lenses or a diffuser can be arranged in front of the light-emitting diode arrangement, as a result of which a reduction in the luminance whilst producing uniform illumination and a directed emission characteristic are made possible.
In accordance with one development of the invention, the alternative luminous means can be attached to the adapter with a different alignment of light, as a result of which different moods can be produced with a type of alternative luminous means.
In addition to one of the abovedescribed adapters, an illumination arrangement according to the invention also has at least one luminous means mount for the alternative luminous means. As a result of the physically separated design of the adapter and the luminous means mount, thermal decoupling between the adapter and the alternative luminous means can be converted more effectively so that, for example, the life of LEDs as the alternative luminous means can be increased.
The luminous means mount is preferably provided with an annular basic section, as a result of which a stable mechanical connection between the adapter and the luminous means mount can be realized. A bridge section on the annular basic section for providing the alternative luminous means improves the thermal decoupling of the adapter and the alternative luminous means.
For a mechanically well-balanced configuration and uniform illumination, the provision of bridge sections in pairs on diametrically opposite circumferential sections of the annular basic section has proven advantageous.
It is preferred that the annular basic section can be attached to the housing of the adapter via at least one latching tab in such a way that the alternative luminous means can be provided with a different light orientation on the adapter. The latching tabs are preferably located on the housing of the adapter. An annular basic section with an alternative luminous means therefore makes it possible to produce different moods.
A mechanical switch for alternatively switching the light source and the alternative luminous means can be arranged on the annular basic section. As a result of this arrangement of the switch and the luminous means mount, an individual operating mode which can be controlled via the switch can be assigned to the individual luminous means. As an alternative to this, the switch is provided on the housing of the adapter, as a result of which the physical size of the luminous means mount can be reduced.
Corresponding to a further alternative, the light source and the alternative luminous means are capable of being actuated via an electronic switch, with the result that the illumination arrangement according to the invention can be switched on via a wall switch without further contacts, apart from the electrical contacts in the conventional lampholder into which the adapter is introduced, for transmitting switching signals to the light source and to the alternative luminous means being required.
The driving of the alternative luminous means, an RGB
individual circuit or a sequencer circuit for the alternative luminous means is preferably provided in the luminous means mount, with the result that, in the adapter, a uniform LED
supply voltage of 10 V, for example, can be made available at electrical contacts of the adapter via a transformer, and this voltage is matched to the characteristic data of the respective LEDs in the luminous means mount itself. This underlines the modular character in the concept corresponding to the present invention.

Preferred embodiment of the invention The invention will be explained below with reference to an incandescent lamp as the main illumination and a light-emitting diode arrangement for producing alternative illumination.
Figure 1 shows a schematic arrangement of a lampholder 60, which is fixed on an electrical cable 62, the adapter 1 according to the invention and an incandescent lamp 20. The lampholder 60, which is fixed on the electrical cable 62, and the incandescent lamp 20 are known from the prior art. In the exemplary embodiment illustrated, the incandescent lamp 20 has a base E27 corresponding to IEC/EN 60061-1, while the lampholder 60 is likewise of the E27 type.
The adapter 1 has a substantially cylindrical housing 2, a base 4 being provided on one axial end section of said housing and a lampholder 6 being provided in the other axial end section thereof. The base 4 and the lampholder 6 are likewise of the E27 type. The adapter 1 according to the invention can therefore be screwed into a lampholder 60 and likewise electrically connected to an incandescent lamp 20, which will screw directly into the lampholder 60 in the prior art.
The housing 2 has a cylindrical housing section 8 which is near to the base and which is adjoined towards the lampholder 6 by a housing section 10 which is remote from the base. The housing section 10 which is remote from the base is likewise cylindrical and has a smaller diameter than the housing section 8 near to the base, with the result that a stepped section is provided between the housing section 8 near to the base and the housing section 10 remote from the base.
Two electrical contacts 12a, 12b are provided in diametrically opposite sides of the housing section 8 near to the base, via which electrical contacts 12a, 12b a voltage can be applied to a light-emitting diode arrangement. A transformer is formed in the housing 2, via which transformer a voltage applied to the base 4 can be transformed into a supply voltage of 10 volts, for example, at the electrical contacts 12a, 12b.
With reference to the side view, plan view and partial view in figures 2A to 2C and with reference to figure 3, a luminous means mount 28 with light-emitting diode arrangements 14a, 14b corresponding to a first exemplary embodiment of the present invention will now be described.
The luminous means mount 28 has, as can be seen in the plan view in figure 2B, a substantially annular basic section 30 with an inner diameter which is slightly larger than the outer diameter of the housing section 8, which is near to the base, of the adapter 1. Electrical contacts 32a, 32b, which are connected to the electrical contact 12a and 12b, respectively, when the luminous means mount 28 has been positioned on the adapter 1, are provided diametrically opposite one another on the inner circumference.
Bridge sections 34a, 34b are arranged on diametrically opposite sections of the outer circumference of the annular basic section 30. As can be seen from the side view in figure 2A, the respective bridge section extends beyond the entire axial length of the luminous means mount 28. In the plan view in figure 2B, one bridge section has the form of two triangles, which are connected to one another at their respective narrowest side and whose pointed end sections are connected to the annular basic section 30 in such a way that a region of touching contact with the smaller face results in the plan view in figure 2B.
A respective light-emitting diode arrangement 14a, 14b is provided in the connecting region between the narrowest sides of the two triangles, a respective circulation space 36a, 36b for air being provided between the outer circumference of the annular basic section 30 and the region of the bridge section 34a, 34b, in which the light-emitting diode arrangements 14a, 14b are provided. These circulation spaces 36a, 36b are also illustrated in figure 2A and serve the purpose that heat in the annular basic section 30, which is present in the luminous means mount 28 despite the thermal decoupling via the annular air gap between the adapter 1 and the luminous means mount 28, only passes to a small extent via thermal conduction to the light-emitting diode arrangement 14a, 14b.
The light-emitting diode arrangement 14a, 14b provided for producing alternative illumination comprises an individual light-emitting diode (LED) emitting white light in the case of the exemplary embodiment shown. In an alternative variant of the invention, the respective light-emitting diode arrangement 14a, 14b comprises a multicolored light-emitting diode or a plurality of multicolored or monochromatic light-emitting diodes. These produce, as a result of a defined mixture of the three primary colors red, green and blue, individual static color mixtures or defined color sequences depending on the type of driving. The light-emitting diodes can have a radial design or can be provided corresponding to the SMT (surface mount technology) design over a mounting plate or a housing on the bridge section 34a, 34b.
Figure 2C shows a partial illustration of the bridge section of the luminous means mount, the light-emitting diode arrangement 14b being illustrated as having been provided with an optical assembly 16. This optical assembly 16 is a lens for achieving a defined emission angle with a maximum quantity of light per surface area or a diffuser for reducing the luminance of the light-emitting diode arrangement 14b. As a result of a reflector adjacent to the light-emitting diode arrangement 14a, 14b, focusing of the radiation emitted by the respective light-emitting diode arrangement is possible.
The respective driving for the light-emitting diode arrangements 14a, 14b is provided in the luminous means mount 28 and is fed via the electrical contacts 32a, 32b. The electronic ballast or the electronic operating device can be capable of being dimmed so as to control the brightness of the light-emitting diode arrangement and/or can be configured with a sensor system for brightness detection. As a result, a strong light emission with reduced energy consumption is achieved.
Figure 3 shows the luminous means mount 28 fitted on the adapter 1, the inner circumference of the annular basic section 30 being located on the outer circumference of the housing section 8 near to the base, and the electrical contact 32a being connected to the electrical contact 12a and the electrical contact 32b being connected to the electrical contact 12b. The light-emitting diode arrangements 14a, 14b point towards the side of the lampholder 6 into which a light source 20 (shown in figure 1) can be introduced.
A snap-action system, with latching tabs, for example, is provided on the adapter 1 and/or on the luminous means mount 28. By way of example, figure 1 shows latching tabs, which protrude radially from the housing section 8 near to the base and engage with the latter when the luminous means mount 28 is positioned. This snap-action system has the effect that the luminous means mount 28 can be positioned on the adapter 1 even with the opposite axial alignment, in which case the light-emitting diode arrangements 14a, 14b point in the direction of the base 4. In other words, the luminous means mount 28 can be positioned on the adapter 1 in such a way that the light-emitting diode arrangement 14a, 14b points in the opposite direction to the direction shown in figure 3, i.e. towards the base 4. As a result of such an indirect illumination by means of the light-emitting diode arrangement 14a, 14b, a wide variety of moods can be realized as a result of the illumination, which moods go beyond the moods which can be realized with the structure shown in figure 3.
The snap-action system on the adapter 1 and/or on the luminous means mount 28 is designed in such a way that, independently of the alignment of the light-emitting diode arrangement 14a, 14ba, the electrical contact 12a is connected to the electrical contact 32a and the electrical contact 12b is connected to the electrical contact 32b.
As an alternative to this, if an alternating voltage is transmitted via the electrical contacts, the snap-action system can also allow any desired assignment of the contacts 12a, 12b with respect to the contacts 32a, 32b. If in this case LEDs are used as the alternative luminous means, the rectifier circuit needs to be integrated into the luminous means mount.
In the case of the illumination arrangement comprising the adapter 1 and the luminous means mount 28 corresponding to the first exemplary embodiment, the switching of the light source 20 and the light-emitting diode arrangement 14a, 14b takes place electronically. In this case, an electronic signal, which is transmitted via the lampholder 50 and the base 4 into the adapter 1, is processed in the adapter 1 in such a way that, as a function of the desired operating state set via a wall switch, either the light source 20 or the light-emitting diode arrangement 14a, 14b is supplied in a desirable manner or the light source 20 and the light-emitting diode arrangement 14a, 14b is supplied with voltage. The dimmed light produced by the light-emitting diode arrangement 14a, 14b can in this case be used, for example, for producing a mood in the space or as orientation means, but can also represent an additional light to the light from the light source 20.
Corresponding to a development of the first exemplary embodiment which is not shown in the figures, a mechanical switch for selectively actuating the light source 20 and/or the light-emitting diode arrangement 14a, 14b is provided on the adapter 1, in particular in the region of the housing section 10, remote from the base. As a result, the desired illumination can be set directly using the illumination arrangement.
Figures 4A to 4C show a luminous means mount 38 corresponding to the second exemplary embodiment of the invention. The luminous means mount 38 from the second exemplary embodiment differs from the luminous means mount 28 from the first exemplary embodiment, which is shown in figures 2A to 2C and in figure 3, merely by virtue of the fact that in the second exemplary embodiment a mechanical switch 46 for setting the operating mode of the light-emitting diode arrangement 14a, 14b and/or the incandescent lamp 20 is provided in the axial direction approximately centrally on the circumference of the annular basic section 40. One advantage here is the fact that a switch which is matched to the specific operating mode of the light-emitting diode arrangement 14a, 14b is associated with the luminous means mount 38. When the luminous means mount 38 is exchanged, the switch 46 is also exchanged, with the result that luminous means mounts 38 with a different physical arrangement of light-emitting diodes and with a different electrical configuration thereof can be used.
With respect to the bridge sections 34a, 34b, the light-emitting diode arrangements 14a, 14b, the electrical contacts 32a, 32b and the optical assembly 16 in the second exemplary embodiment, reference is made to the description of the component parts provided with the same reference symbols in the first exemplary embodiment. In figure 4A, the electrical contacts 32a, 32b are indicated in terms of position for reasons of clarity although they remain hidden to the viewer in a front view. It can be seen in figure 4B that the electrical contacts 32a, 32b are located on the inner circumference of the annular basic section, as is also the case in the first exemplary embodiment.
In addition or as an alternative to the mechanical switch 46 on the annular basic section 40, a mechanical switch can be fitted to the housing section 10 remote from the base and/or an electrical switch can be realized via a wall switch. This further electrical or mechanical switch then serves the purpose, for example, of alternatively or simultaneously switching the incandescent lamp 20 and the light-emitting diode arrangements 14a, 14b. In this case, the mechanical switch 46 is then exclusively used for switching over from the different operating modes of the light-emitting diode arrangements 14a, 14b, for example.
Figure 6 shows a development of the luminous means mount 38 corresponding to the second exemplary embodiment. Corresponding to this development, in addition to the bridge section 34b, further bridge sections 56b, 58b are provided with the respectively associated light-emitting diode arrangement offset in the circumferential direction of the annular basic section. These bridge sections 56b, 58b are located at different heights in the axial direction. The number of additional light-emitting diode arrangements on bridge sections is not restricted, but rather any desired number of them can be provided on the luminous means mount 38. The use of bridge sections is advantageous for thermal decoupling.
Thermal decoupling between the annular basic section 40 and the light-emitting diode arrangement can be realized, however, in any desired manner, for example even by means of a large distance in the radial direction from light-emitting diode arrangements arranged on a ring (not illustrated in the figures) with respect to the annular basic section 40. In the case of such a ring, the light-emitting diode arrangements are not offset in their axial direction in contrast to figure 6, but are arranged at one height.
In a further alternative, the bridge sections 34b, 56b, 58b and the associated oppositely arranged bridge sections (not illustrated in figure 6) can be arranged at the same height in the axial direction.
The use of the above-explained multiplicity of light-emitting diode arrangements is not restricted to the second exemplary embodiment, but can also take place in the case of the first exemplary embodiment of the present invention.
Corresponding to a further alternative of the present invention, a multiplicity of luminous means mounts can be used on an adapter one behind the other in the axial direction so long as it is ensured that voltage can be fed to each luminous means mount via associated electrical contacts. In order to achieve desired illumination effects, the distance between the light-emitting diode arrangements and the annular basic section can increase with the reducing distance from the base 4 for this purpose. Each of these luminous means mounts can in this case either be actuated by a switch provided on it, by one or more switches on the adapter and/or by a wall switch. This structure also includes the arrangement of at least two luminous means mounts which direct light in opposite directions, i.e. for example in the direction of the base 4 and the lampholder 6.
The abovementioned first and second exemplary embodiments have been described with the lampholder 6 and the base 4 as well as the lampholder 60 of the E27 type. However, the present invention is not restricted to this, but rather any desired lampholder, including the screw-type lampholder such as E14, E40 or the bayonet type, such as B22d, can be used. In this case, the type of lampholder 6 on the adapter can differ from the type of base 4 on the adapter. As a result, the use of light sources 20 is therefore possible which could not be used in the lampholder 60 as a result of their base.
Not only a general-service incandescent lamp can be used for the light source 20, but instead any light source which can be accommodated in a lampholder which may be provided in the adapter. Such light sources are, for example, halogen incandescent lamps and compact fluorescent lamps.
It is also possible in the case of the abovedescribed adapters or illumination arrangements to use a light sensor in the adapter or in the luminous means mount, by means of which light sensor a fully automatic operation for the light source 20 and/or the light-emitting diode arrangement 14a, 14b can be realized.
The abovedescribed snap-action system between the adapter 1 and the luminous means mount can also be designed in such a way that a luminous means mount can be provided in different rotary positions on the outer circumference of the annular basic section. A mood which can be achieved with the light or the optical configuration of orientation points can be therefore influenced in a more targeted manner using only one luminous means mount.
The invention discloses an adapter for a light source and at least one alternative luminous means with a base for supplying electrical current, a lampholder for the electrical connection between the base and the light source and at least two electrical contacts for supplying voltage to the alternative luminous means. The illumination arrangement according to the invention has such an adapter and a luminous means mount for the alternative luminous means.

Prior art WO 02/062106 Al has disclosed a lamp arrangement with a compact fluorescent lamp with a base at one end for producing main illumination and with a light-emitting diode arrangement for producing alternative illumination, in the case of which the light-emitting diodes are arranged in an annular space between the discharge vessel of the compact fluorescent lamp and an envelope on the base. This lamp arrangement provides control electronics, via which the lamp arrangement can be operated in the main illumination mode, the alternative illumination mode or in both illumination modes simultaneously as a function of an actuation sequence of a wall switch.
One disadvantage with such lamp arrangements is the fact that the heat-sensitive light-emitting diodes are arranged in a region which is subjected to high thermal loads of electrode filaments which are arranged in end sections of the discharge tubes and are heated so as to produce free electrons. As a result of the thermal loading of the light-emitting diodes, the light emission decreases as the temperature of the discharge tubes increases. Furthermore, the thermal loading results in a reduced life of the light-emitting diodes and, once the maximum operating temperature has been reached, in their failure. The thermal loading of the light-emitting diodes is further intensified by an envelope used in the prior art in accordance with WO 02/062106 Al as a result of the reduced heat emission of the lamp arrangement and the thereby increasing internal temperature of the envelope.
Yet even when the light-emitting diodes are arranged in a region of the discharge tubes with low thermal loading there is still the disadvantage that, as a result of the rigid fixing of the light-emitting diodes on the lamp arrangement, the direction of light of the light-emitting diodes and the type of light-emitting diodes in the lamp arrangement cannot be altered. Furthermore, in the event of failure of the compact fluorescent lamp, the light-emitting diodes need to be replaced together with the fluorescent lamp.
As a result of the combined arrangement of the compact fluorescent lamp and the light-emitting diodes, it is not possible to use conventional light sources, such as general-service incandescent lamps (GLS lamps), halogen incandescent lamps or compact fluorescent lamps, for example.
Description of the invention The invention is based on the object of providing a lamp arrangement with at least one light source for producing main illumination and with at least one alternative light source, in particular a light-emitting diode arrangement, for producing alternative illumination, which lamp arrangement makes improved light emission of the light-emitting diode arrangement possible in desired directions with an extended life, significantly broader use possibilities and low costs in comparison with conventional solutions.
This object is achieved according to the invention by an adapter as claimed in claim 1 and an illumination arrangement as claimed in claim 9. Particularly advantageous embodiments of the invention are described in the dependent claims.
The adapter according to the invention for a light source and at least one alternative luminous means has a base for the supply of current, a lampholder for electrically connecting the light source and the base and at least two electrical contacts for the supply of voltage to the alternative luminous means.
This configuration means that standard light sources, such as lamps with a base at one end, for example, such as GLS lamps, high-volt halogen lamps or DULUX-EL lamps, can be used without any structural intervention in the standard light source itself with LED illumination together in lampholders known from the prior art. Therefore only the adapter is required as the additional component part.
Preferably, the adapter has a substantially cylindrical housing, with the result that there is no significant optical disruption of the overall impression if at least partially rotationally symmetrical light sources, such as incandescent lamps, for example, are used.
The base and the lampholder are preferably arranged opposite one another on the adapter. This allows for the conventional lampholder, adapter and incandescent lamp to be arranged one behind the other, in which arrangement the illumination of a space with the incandescent lamp changes only slightly in comparison with the incandescent lamp being screwed directly into the conventional lampholder.
It is advantageous if the light source is operated on the system voltage in order to achieve a high luminance when using the light source. In contrast to the illumination by means of the alternative luminous means, which can be used in the form of an LED arrangement for producing a mood or for orientation purposes or for defined task lighting with low energy, desired general lighting can thus be provided.
As a result of the widespread availability of the bases such as E27, E14, B22d, for example, general-service incandescent lamps, halogen incandescent lamps or compact fluorescent lamps are preferably used as the light sources.
It is preferable to use a light-emitting diode arrangement as the alternative luminous means. The light from the light-emitting diodes is suitable for producing moods or for orientation purposes as a result of the luminous flux which is at present still low. However, it is also possible for them to be used as directed task lighting. In this case, an optical assembly with the function of scattering or focusing lenses or a diffuser can be arranged in front of the light-emitting diode arrangement, as a result of which a reduction in the luminance whilst producing uniform illumination and a directed emission characteristic are made possible.
In accordance with one development of the invention, the alternative luminous means can be attached to the adapter with a different alignment of light, as a result of which different moods can be produced with a type of alternative luminous means.
In addition to one of the abovedescribed adapters, an illumination arrangement according to the invention also has at least one luminous means mount for the alternative luminous means. As a result of the physically separated design of the adapter and the luminous means mount, thermal decoupling between the adapter and the alternative luminous means can be converted more effectively so that, for example, the life of LEDs as the alternative luminous means can be increased.
The luminous means mount is preferably provided with an annular basic section, as a result of which a stable mechanical connection between the adapter and the luminous means mount can be realized. A bridge section on the annular basic section for providing the alternative luminous means improves the thermal decoupling of the adapter and the alternative luminous means.
For a mechanically well-balanced configuration and uniform illumination, the provision of bridge sections in pairs on diametrically opposite circumferential sections of the annular basic section has proven advantageous.
It is preferred that the annular basic section can be attached to the housing of the adapter via at least one latching tab in such a way that the alternative luminous means can be provided with a different light orientation on the adapter. The latching tabs are preferably located on the housing of the adapter. An annular basic section with an alternative luminous means therefore makes it possible to produce different moods.
A mechanical switch for alternatively switching the light source and the alternative luminous means can be arranged on the annular basic section. As a result of this arrangement of the switch and the luminous means mount, an individual operating mode which can be controlled via the switch can be assigned to the individual luminous means. As an alternative to this, the switch is provided on the housing of the adapter, as a result of which the physical size of the luminous means mount can be reduced.
Corresponding to a further alternative, the light source and the alternative luminous means are capable of being actuated via an electronic switch, with the result that the illumination arrangement according to the invention can be switched on via a wall switch without further contacts, apart from the electrical contacts in the conventional lampholder into which the adapter is introduced, for transmitting switching signals to the light source and to the alternative luminous means being required.
The driving of the alternative luminous means, an RGB
individual circuit or a sequencer circuit for the alternative luminous means is preferably provided in the luminous means mount, with the result that, in the adapter, a uniform LED
supply voltage of 10 V, for example, can be made available at electrical contacts of the adapter via a transformer, and this voltage is matched to the characteristic data of the respective LEDs in the luminous means mount itself. This underlines the modular character in the concept corresponding to the present invention.

Preferred embodiment of the invention The invention will be explained below with reference to an incandescent lamp as the main illumination and a light-emitting diode arrangement for producing alternative illumination.
Figure 1 shows a schematic arrangement of a lampholder 60, which is fixed on an electrical cable 62, the adapter 1 according to the invention and an incandescent lamp 20. The lampholder 60, which is fixed on the electrical cable 62, and the incandescent lamp 20 are known from the prior art. In the exemplary embodiment illustrated, the incandescent lamp 20 has a base E27 corresponding to IEC/EN 60061-1, while the lampholder 60 is likewise of the E27 type.
The adapter 1 has a substantially cylindrical housing 2, a base 4 being provided on one axial end section of said housing and a lampholder 6 being provided in the other axial end section thereof. The base 4 and the lampholder 6 are likewise of the E27 type. The adapter 1 according to the invention can therefore be screwed into a lampholder 60 and likewise electrically connected to an incandescent lamp 20, which will screw directly into the lampholder 60 in the prior art.
The housing 2 has a cylindrical housing section 8 which is near to the base and which is adjoined towards the lampholder 6 by a housing section 10 which is remote from the base. The housing section 10 which is remote from the base is likewise cylindrical and has a smaller diameter than the housing section 8 near to the base, with the result that a stepped section is provided between the housing section 8 near to the base and the housing section 10 remote from the base.
Two electrical contacts 12a, 12b are provided in diametrically opposite sides of the housing section 8 near to the base, via which electrical contacts 12a, 12b a voltage can be applied to a light-emitting diode arrangement. A transformer is formed in the housing 2, via which transformer a voltage applied to the base 4 can be transformed into a supply voltage of 10 volts, for example, at the electrical contacts 12a, 12b.
With reference to the side view, plan view and partial view in figures 2A to 2C and with reference to figure 3, a luminous means mount 28 with light-emitting diode arrangements 14a, 14b corresponding to a first exemplary embodiment of the present invention will now be described.
The luminous means mount 28 has, as can be seen in the plan view in figure 2B, a substantially annular basic section 30 with an inner diameter which is slightly larger than the outer diameter of the housing section 8, which is near to the base, of the adapter 1. Electrical contacts 32a, 32b, which are connected to the electrical contact 12a and 12b, respectively, when the luminous means mount 28 has been positioned on the adapter 1, are provided diametrically opposite one another on the inner circumference.
Bridge sections 34a, 34b are arranged on diametrically opposite sections of the outer circumference of the annular basic section 30. As can be seen from the side view in figure 2A, the respective bridge section extends beyond the entire axial length of the luminous means mount 28. In the plan view in figure 2B, one bridge section has the form of two triangles, which are connected to one another at their respective narrowest side and whose pointed end sections are connected to the annular basic section 30 in such a way that a region of touching contact with the smaller face results in the plan view in figure 2B.
A respective light-emitting diode arrangement 14a, 14b is provided in the connecting region between the narrowest sides of the two triangles, a respective circulation space 36a, 36b for air being provided between the outer circumference of the annular basic section 30 and the region of the bridge section 34a, 34b, in which the light-emitting diode arrangements 14a, 14b are provided. These circulation spaces 36a, 36b are also illustrated in figure 2A and serve the purpose that heat in the annular basic section 30, which is present in the luminous means mount 28 despite the thermal decoupling via the annular air gap between the adapter 1 and the luminous means mount 28, only passes to a small extent via thermal conduction to the light-emitting diode arrangement 14a, 14b.
The light-emitting diode arrangement 14a, 14b provided for producing alternative illumination comprises an individual light-emitting diode (LED) emitting white light in the case of the exemplary embodiment shown. In an alternative variant of the invention, the respective light-emitting diode arrangement 14a, 14b comprises a multicolored light-emitting diode or a plurality of multicolored or monochromatic light-emitting diodes. These produce, as a result of a defined mixture of the three primary colors red, green and blue, individual static color mixtures or defined color sequences depending on the type of driving. The light-emitting diodes can have a radial design or can be provided corresponding to the SMT (surface mount technology) design over a mounting plate or a housing on the bridge section 34a, 34b.
Figure 2C shows a partial illustration of the bridge section of the luminous means mount, the light-emitting diode arrangement 14b being illustrated as having been provided with an optical assembly 16. This optical assembly 16 is a lens for achieving a defined emission angle with a maximum quantity of light per surface area or a diffuser for reducing the luminance of the light-emitting diode arrangement 14b. As a result of a reflector adjacent to the light-emitting diode arrangement 14a, 14b, focusing of the radiation emitted by the respective light-emitting diode arrangement is possible.
The respective driving for the light-emitting diode arrangements 14a, 14b is provided in the luminous means mount 28 and is fed via the electrical contacts 32a, 32b. The electronic ballast or the electronic operating device can be capable of being dimmed so as to control the brightness of the light-emitting diode arrangement and/or can be configured with a sensor system for brightness detection. As a result, a strong light emission with reduced energy consumption is achieved.
Figure 3 shows the luminous means mount 28 fitted on the adapter 1, the inner circumference of the annular basic section 30 being located on the outer circumference of the housing section 8 near to the base, and the electrical contact 32a being connected to the electrical contact 12a and the electrical contact 32b being connected to the electrical contact 12b. The light-emitting diode arrangements 14a, 14b point towards the side of the lampholder 6 into which a light source 20 (shown in figure 1) can be introduced.
A snap-action system, with latching tabs, for example, is provided on the adapter 1 and/or on the luminous means mount 28. By way of example, figure 1 shows latching tabs, which protrude radially from the housing section 8 near to the base and engage with the latter when the luminous means mount 28 is positioned. This snap-action system has the effect that the luminous means mount 28 can be positioned on the adapter 1 even with the opposite axial alignment, in which case the light-emitting diode arrangements 14a, 14b point in the direction of the base 4. In other words, the luminous means mount 28 can be positioned on the adapter 1 in such a way that the light-emitting diode arrangement 14a, 14b points in the opposite direction to the direction shown in figure 3, i.e. towards the base 4. As a result of such an indirect illumination by means of the light-emitting diode arrangement 14a, 14b, a wide variety of moods can be realized as a result of the illumination, which moods go beyond the moods which can be realized with the structure shown in figure 3.
The snap-action system on the adapter 1 and/or on the luminous means mount 28 is designed in such a way that, independently of the alignment of the light-emitting diode arrangement 14a, 14ba, the electrical contact 12a is connected to the electrical contact 32a and the electrical contact 12b is connected to the electrical contact 32b.
As an alternative to this, if an alternating voltage is transmitted via the electrical contacts, the snap-action system can also allow any desired assignment of the contacts 12a, 12b with respect to the contacts 32a, 32b. If in this case LEDs are used as the alternative luminous means, the rectifier circuit needs to be integrated into the luminous means mount.
In the case of the illumination arrangement comprising the adapter 1 and the luminous means mount 28 corresponding to the first exemplary embodiment, the switching of the light source 20 and the light-emitting diode arrangement 14a, 14b takes place electronically. In this case, an electronic signal, which is transmitted via the lampholder 50 and the base 4 into the adapter 1, is processed in the adapter 1 in such a way that, as a function of the desired operating state set via a wall switch, either the light source 20 or the light-emitting diode arrangement 14a, 14b is supplied in a desirable manner or the light source 20 and the light-emitting diode arrangement 14a, 14b is supplied with voltage. The dimmed light produced by the light-emitting diode arrangement 14a, 14b can in this case be used, for example, for producing a mood in the space or as orientation means, but can also represent an additional light to the light from the light source 20.
Corresponding to a development of the first exemplary embodiment which is not shown in the figures, a mechanical switch for selectively actuating the light source 20 and/or the light-emitting diode arrangement 14a, 14b is provided on the adapter 1, in particular in the region of the housing section 10, remote from the base. As a result, the desired illumination can be set directly using the illumination arrangement.
Figures 4A to 4C show a luminous means mount 38 corresponding to the second exemplary embodiment of the invention. The luminous means mount 38 from the second exemplary embodiment differs from the luminous means mount 28 from the first exemplary embodiment, which is shown in figures 2A to 2C and in figure 3, merely by virtue of the fact that in the second exemplary embodiment a mechanical switch 46 for setting the operating mode of the light-emitting diode arrangement 14a, 14b and/or the incandescent lamp 20 is provided in the axial direction approximately centrally on the circumference of the annular basic section 40. One advantage here is the fact that a switch which is matched to the specific operating mode of the light-emitting diode arrangement 14a, 14b is associated with the luminous means mount 38. When the luminous means mount 38 is exchanged, the switch 46 is also exchanged, with the result that luminous means mounts 38 with a different physical arrangement of light-emitting diodes and with a different electrical configuration thereof can be used.
With respect to the bridge sections 34a, 34b, the light-emitting diode arrangements 14a, 14b, the electrical contacts 32a, 32b and the optical assembly 16 in the second exemplary embodiment, reference is made to the description of the component parts provided with the same reference symbols in the first exemplary embodiment. In figure 4A, the electrical contacts 32a, 32b are indicated in terms of position for reasons of clarity although they remain hidden to the viewer in a front view. It can be seen in figure 4B that the electrical contacts 32a, 32b are located on the inner circumference of the annular basic section, as is also the case in the first exemplary embodiment.
In addition or as an alternative to the mechanical switch 46 on the annular basic section 40, a mechanical switch can be fitted to the housing section 10 remote from the base and/or an electrical switch can be realized via a wall switch. This further electrical or mechanical switch then serves the purpose, for example, of alternatively or simultaneously switching the incandescent lamp 20 and the light-emitting diode arrangements 14a, 14b. In this case, the mechanical switch 46 is then exclusively used for switching over from the different operating modes of the light-emitting diode arrangements 14a, 14b, for example.
Figure 6 shows a development of the luminous means mount 38 corresponding to the second exemplary embodiment. Corresponding to this development, in addition to the bridge section 34b, further bridge sections 56b, 58b are provided with the respectively associated light-emitting diode arrangement offset in the circumferential direction of the annular basic section. These bridge sections 56b, 58b are located at different heights in the axial direction. The number of additional light-emitting diode arrangements on bridge sections is not restricted, but rather any desired number of them can be provided on the luminous means mount 38. The use of bridge sections is advantageous for thermal decoupling.
Thermal decoupling between the annular basic section 40 and the light-emitting diode arrangement can be realized, however, in any desired manner, for example even by means of a large distance in the radial direction from light-emitting diode arrangements arranged on a ring (not illustrated in the figures) with respect to the annular basic section 40. In the case of such a ring, the light-emitting diode arrangements are not offset in their axial direction in contrast to figure 6, but are arranged at one height.
In a further alternative, the bridge sections 34b, 56b, 58b and the associated oppositely arranged bridge sections (not illustrated in figure 6) can be arranged at the same height in the axial direction.
The use of the above-explained multiplicity of light-emitting diode arrangements is not restricted to the second exemplary embodiment, but can also take place in the case of the first exemplary embodiment of the present invention.
Corresponding to a further alternative of the present invention, a multiplicity of luminous means mounts can be used on an adapter one behind the other in the axial direction so long as it is ensured that voltage can be fed to each luminous means mount via associated electrical contacts. In order to achieve desired illumination effects, the distance between the light-emitting diode arrangements and the annular basic section can increase with the reducing distance from the base 4 for this purpose. Each of these luminous means mounts can in this case either be actuated by a switch provided on it, by one or more switches on the adapter and/or by a wall switch. This structure also includes the arrangement of at least two luminous means mounts which direct light in opposite directions, i.e. for example in the direction of the base 4 and the lampholder 6.
The abovementioned first and second exemplary embodiments have been described with the lampholder 6 and the base 4 as well as the lampholder 60 of the E27 type. However, the present invention is not restricted to this, but rather any desired lampholder, including the screw-type lampholder such as E14, E40 or the bayonet type, such as B22d, can be used. In this case, the type of lampholder 6 on the adapter can differ from the type of base 4 on the adapter. As a result, the use of light sources 20 is therefore possible which could not be used in the lampholder 60 as a result of their base.
Not only a general-service incandescent lamp can be used for the light source 20, but instead any light source which can be accommodated in a lampholder which may be provided in the adapter. Such light sources are, for example, halogen incandescent lamps and compact fluorescent lamps.
It is also possible in the case of the abovedescribed adapters or illumination arrangements to use a light sensor in the adapter or in the luminous means mount, by means of which light sensor a fully automatic operation for the light source 20 and/or the light-emitting diode arrangement 14a, 14b can be realized.
The abovedescribed snap-action system between the adapter 1 and the luminous means mount can also be designed in such a way that a luminous means mount can be provided in different rotary positions on the outer circumference of the annular basic section. A mood which can be achieved with the light or the optical configuration of orientation points can be therefore influenced in a more targeted manner using only one luminous means mount.
The invention discloses an adapter for a light source and at least one alternative luminous means with a base for supplying electrical current, a lampholder for the electrical connection between the base and the light source and at least two electrical contacts for supplying voltage to the alternative luminous means. The illumination arrangement according to the invention has such an adapter and a luminous means mount for the alternative luminous means.
