Instead of an individual light-emitting diode in each case, however, a group of light-emitting diodes can also be combined in each case.

The two light-emitting diodes 1 and 2 are arranged on a carrier element 5 in such a way that the carrier element 5 is designed as a polygon in which at least two side faces converge and the light-emitting diodes 1 and 2 are arranged on the side faces of the carrier element 5 . The light-emitting diodes 1 and 2 are advantageously arranged in the middle of a side face of the carrier element 5 .

With escape route lighting, it is important to illuminate an escape corridor that is as long as possible but not very wide. For this application, the light source A with the two light-emitting diodes 1 and 2 on the converging side faces of the wedge-shaped

The light-emitting diodes 1 and 2 can be attached directly to the carrier element 5 or by a contact element on the carrier element 5 . The contact element can be designed, for example, as a double-sided adhesive tape, which advantageously has high thermal conductivity, and can be attached to the carrier element 5

The carrier element 5 advantageously has a high thermal conductivity in order to effectively dissipate the heat generated by the light-emitting diodes 1 and 2 and the temperature

of the LED semiconductor chips as low as possible.

The carrier element 5 can also at least partially have a reflective surface in order to achieve better light decoupling by the light-emitting diodes 1 and 2 .

The carrier element 5 can consist of a ceramic substrate, a synthetic resin material, glass or a silicon substrate. In a special embodiment, the carrier element 5 can consist of a ceramic substrate. The ceramic substrate can preferably be implemented as an LTCC structure (Low Temperature Cofired Ceramic). By using an LTCC structure, at least partial integration of components such as resistors or capacitors or conductor tracks is possible. Due to the at least partial integration, part of the control electronics 36 for the light-emitting diodes 1 and 2 can be integrated into the carrier element 5 . At the part

In a further development of the idea, a lighting system having a plurality of light sources A can also be set up. The lighting means A can be positioned in a predetermined arrangement relative to one another. Thus, when the overall brightness is increased, a defined illumination can be achieved by the illuminant.

The illuminant A can either be attached directly to the ceiling 11 by means of the carrier element 5 in the case of an embodiment without a reflector 6 or directly in the ceiling 11 in the case of an embodiment with a reflector 6 as a built-in lamp. In the embodiment with a reflector 6, the ends of the outer sides of the reflector 6 can be connected directly to the ceiling 11, as shown in FIG. Thus, the lamp A can be sunk into the ceiling 11 and can

thus integrate into the ceiling construction.

FIG. 17 shows a perspective view of a carrier element 5 according to a development of the invention.

Fig. 18 shows a front view of a carrier element 5.

In this exemplary embodiment, the carrier element 5 consists of a heat sink 15 and at least one LED carrier 16.

The LED carrier 16 can be replaced by individual printed circuit boards

An LED carrier 16 can be placed on each side surface of the heat sink 15 . At least one light-emitting diode 1 or 2 and the electrical supply line 17 for making electrical contact with the light-emitting diode 1 or 2 are applied to the LED carrier 16 .

The LED carrier 16, for example, made of a synthetic resin material (FR4 or CEM1l) or from a

Ceramic substrate exist as LTCC structure.

The heat sink 15 advantageously consists of a material with good thermal conductivity and can also be mechanically stable. In a special embodiment, the heat sink 15 can consist of a ceramic substrate. The heat sink 15 advantageously has one or more indentations 18 . These indentations 18 enable better cooling of the carrier element 5, since they form channels through which air can flow and thus improve the heat dissipation. The indentations 18 run transversely through the heat sink 15, advantageously parallel to an outer edge of the heat sink 15. In a particular embodiment, the heat sink 15 is designed in such a way that it consists of a large number of laminations joined together. A possible embodiment of the heat sink 15

is shown in Fig.19.

The depressions 18 of the heat sink 15 can be arranged in such a way that they form channels that use a kind of chimney effect, so that a draft for cooling can form via appropriately arranged ventilation openings 19 . For example, the indentations can be 18

Run in the direction of the upper end of the heat sink 15, so that the air heated on the heat sink 15 and over the LED carrier 16 (and thus through the light-emitting diodes 1, 2) rises and can exit through the upper ventilation openings 19, while over at the lower edge of the LED carrier 16 or of the carrier element 5 existing ventilation openings 19 cooler air can enter. This air can thus through the

The cooling body 15 can have holding means for fixing the or

the LED carrier 16 have.

In addition to the heat sink 15, further cooling devices, such as a heat pipe, a Peltier element or, can be provided within the carrier element 5

also a fan.

The LED carrier 16 advantageously has ventilation openings 19 on its lateral edges. The ventilation openings 19 allow air flow below the LED carrier 16 through the recesses 18 of the heat sink 15. Advantageously, the ventilation openings 19 are arranged so that they are each above the recesses 18 of the heat sink 15 and thus an optimal

enable heat dissipation.

The carrier element 5 can also be formed only by the LED carrier 16, in which case a heat sink 15 is dispensed with. For example, the LED carrier 16 itself can then have means for dissipating heat. For example, it can be vias or integrated thermally conductive layers

be formed in a multi-layer design of the LED carrier 16 by using a metal layer. The metal layer can, for example, through a layer within the LED carrier 16 or through the bottom or

top layer of the LED carrier 16 are formed.

The carrier element 5 can be placed on a base module 20, as shown in FIG. The base module 20 can contain part of the control electronics 36 for the light-emitting diodes 1.2. A battery 38 can also be accommodated in the base module 20 . In addition, the attachment of the lamp A to a ceiling or to a lamp by fasteners,

which has the base module 20 can be ensured.

The carrier element 5 can be detachably attached to the base module 20 . It can be connected to the base module 20, for example, by a screw connection, a plug-in connection with barbs or else by a bayonet catch. It is thus possible, for example, to combine different carrier elements 5 (with a different number of side faces or light-emitting diodes) with different base modules 20 as one

to combine the modular system.

A reflector 6 can be placed on the carrier element 5 and the base module 20, as shown in Fig. 22

is shown.

Further views of the illuminant A with the base module 20 and a reflector 6 are shown in FIGS. 23, 23a, 24 and 25.

As already explained with reference to FIG. 13, a reflector 6 can be placed on the carrier element 5 and surround it. The reflector 6 can have openings for the light-emitting diodes 1 and 2 . The reflector 6 has recesses 23 around the openings for the light-emitting diodes 1 and 2 . These recesses 23 are used for improved light control and focus the light in a predetermined emission direction. In this way, the formation of the light cones 7 and 8 can be improved and, for example, the beam angle can be fixed. In this way, a large part of the light can be emitted in the specified direction of emission. The recesses 23 are advantageously formed in the shape of a semicircle or parabola. For example, the light-emitting diode 1 is arranged in the center of the recess 23 or at least in the vicinity of the center. The light-emitting diode 1 can also be located in or near the focal point of the semicircular or parabolic recess 23, so that a large part of the light emitted by the light-emitting diode 1 is in one

Light cone 7 is bundled.

A section of the illuminant A with the base module 20 and a reflector 6 is shown in FIG. There is the recess 23 with the light-emitting diode 1 arranged in the recess 23 and the light cone 7 that is generated

shown.

The reflector 6 can also have a status LED 24, which is controlled by the integrated control electronics 36 and can emit a signal in the event of an error or for maintenance purposes. The status LED 24 can also show other information such as the address of the lamp A

spend. The status LED 24 can be a two-color

Light-emitting diode are formed and thus output different colors. The different colors can be used to signal different statuses, feedback or errors. The status LED 24 can also be arranged on the carrier element 5 and the reflector 6 can have an opening through which the status LED 24 protrudes or is visible through it. In an advantageous embodiment, the status LED 24 is arranged in such a way that it is at the tip of the reflector 6

or at the top of the carrier element 5 is located.

However, the status LED 24 can also be attached to another location of the illuminant A, for example in or on

the base module 20.

The base module 20 can have the shape of a truncated pyramid, for example, and thus form an optical extension of the carrier element 5 . However, the base module 20 can also have a round cross section and, for example, have the shape of a truncated cone and thus form an optical extension of the carrier element 5 with the reflector 6 attached, as in Fig. 25

shown.

The base module 20 can be made, for example, from a plastic material or from a metallic one

FIGS. 29 and 30 show a view of the lighting means A in cross section.

The base module 20 with the base plate 21 used can contain part of the control electronics 36 for the light-emitting diodes 1,2. A battery 38 can also be accommodated in the base module 20 . In addition, the attachment of the illuminant A to a ceiling or also to a lamp by means of the base plate 21 can be ensured by attachment means such as attachment holes 28 . The bottom plate 21 can

furthermore have a cable passage 26 .

The control electronics 36 can be located on a printed circuit board 46 . The circuit board 46 can either be attached directly to the base plate 21 or the base module 20 or to a retaining plate 44. The retaining plate 44 can be located inside the base module 20 or on the base plate 21. The control electronics 36 and/or the battery 38 can also be attached to the holding plate 44 .

The battery 38 can be secured to the support plate 44 via a releasable connection, such as a clamp connection 42, which can fix the battery 38 in place in one or more locations. The control electronics 36 may have contacting means 34 which, for example, on the circuit board 46 or

The bottom plate 21 can be detachably connected to the base module 20 . It can be connected to the base module 20, for example, by a screw connection, a plug-in connection with barbs or else by a bayonet catch. A connection is also possible in that the base plate is connected at one point to the base module 20 via a pivoting mechanism 30 such as a hinge, and is additionally connected at a second point via a further bracket. This additional mount can be realized, for example, by a mount with barbs 32 . It is thus possible to at least partially detach the base plate 21 from the base module 20 in order, for example, to replace the battery 38 contained therein, to change the wiring or contacting or to gain access to the

Control electronics 36 to have.

The battery 38, which is arranged within the base module 20, can be used to supply the light-emitting diodes 1,2. In particular, in an emergency lighting case, for example, in the event of a mains voltage failure, the supply of light-emitting diodes 1.2 by the

Control electronics 36 are fed from the battery 38.

The control electronics 36 can be controlled via an interface. In this case, the control electronics 36 can contain an interface circuit.

The interface can be suitable for wired or wireless communication. For example, the light source A and its electronic control system 36 can be controlled via a DALI bus or another wired digital bus. The illuminant A and

Communication such as a radio link or an infrared link can be controlled. For example, brightness, maintenance or status commands can be sent to and/or from the illuminant A via the interface. If a sensor, such as a temperature, brightness or color sensor, is part of the control electronics 36, information from the sensor can also be transmitted via the interface. The brightness and/or the color rendering of the light-emitting diodes 1, 2 can be set and regulated via the control electronics 36. If the illuminant A has an interface, this brightness and/or the color rendering of the

LEDs 1, 2 are controlled.

In an advantageous embodiment, the control electronics 36 are arranged on the circuit board 46 in the illuminant A in such a way that they lie in a plane parallel to the underside of the carrier element 5 . This makes it possible to construct a light source A with a relatively low overall height, while still achieving very good light distribution through the emitted light

can be.

Instead of or in addition to the base plate 21, the illuminant A can also have a screw or plug-in base, via which the illuminant A can be inserted into a socket for lamps. This socket for lamps can, for example, be a socket for incandescent lamps (e.g. E27), for halogen lamps or also for fluorescent lamps

In a further development of the idea, a lighting system having a plurality of light sources A can also be set up. The lighting means A can be positioned in a predetermined arrangement relative to one another. Thus, when the overall brightness is increased, a defined illumination can be achieved by the illuminant. The carrier elements 5 can be arranged on the light source A, for example, in a rectangular, circular or triangular arrangement or also in a matrix arrangement. Since the carrier elements 5 can be detached from the base module 20 in a preferred embodiment, different forms of carrier elements 5 can also be combined within a lighting system, depending on the respective lighting requirements of the respective part of the room. For example, a light source A with two light-emitting diodes 1 and 2 on the converging side surfaces of the wedge-shaped support element 5 can be used to illuminate an elongated corridor, while a support element 5 with four LEDs 1, 2, 3 and 4 can be used. As already mentioned, this use of a carrier element 5 with four side faces enables a square area to be illuminated uniformly and over a large area. Alternatively, a carrier element 5 with three side surfaces can also be used here

be used.

The lighting means A according to the invention can be used, for example, to implement emergency lighting such as escape route lighting or emergency route lighting. This illuminant A can already contain the required contacting means 34, control electronics 36 and possibly also a battery 38 and at the same time enables a very good light output and -

distribution with the most compact design possible.

Alternatively, other lighting applications in buildings and rooms or outdoors (outside buildings, such as street lighting)

feasible.

Such lamps A in a lighting system can be networked with each other via their interface and, in addition to the information that the user sends, on each other information, for example, the partial

transfer and exchange the sensors contained.
