Overall, so are the lighting module 42 all heat-generating components, namely the light-emitting diodes 48 and the electronic components 50 , as well as the tracks 58 heat transferring with the cooling surface 64 on the outside of the carrier body 46 connected.

The control devices 52 with the adjustment components 56 and the connection components 54 are in the region of the short transverse side of the carrier main section 60 arranged. The connection components 54 are located next to the short transverse side. The control devices 52 with the connection components 54 and the adjustment components 56 take up about half the length of the main body section 60 on.

The control devices 52 is designed so that it provides a supply voltage of the street lamp 10 in the form of an alternating voltage in output voltages for the light-emitting diodes 48 in the form of DC voltages can convert. The DC voltage for the LEDs 48 may be pulsating, for example. The height of the supply voltage may be for example about 230 volts. The height of the output voltage for the LEDs 48 can be about the same order of magnitude as the supply voltage. With the control device 52 respective lighting circuits can be switched on or off.

On half of the vehicle main section 60 , which faces the long transverse side, is a plurality of light-emitting diodes 48 arranged distributed. The light-emitting diodes 48 on the carrier main section 60 are exemplary in four rows 70 with four groups each 72 each with five LEDs 48 arranged. The light-emitting diodes 48 of each group 72 are each the same control device 52 assigned. The groups 72 a respective row 70 are alternately the two control devices 52 assigned. Overall, these are adjacent groups 72 various control devices 52 assigned. The rows 70 with light-emitting diodes 48 are spaced from each other.

At each support side section 62 are two rows 74 each with 14 groups 76 with light-emitting diodes 48 arranged. Every group 76 has two light-emitting diodes by way of example 48 on. The light-emitting diodes 48 of each group 76 are different control devices 52 assigned. The groups 76 are spaced from each other.

The spaces between the cooling surface 64 between the LEDs 48 on the carrier main section 60 and the carrier side sections 62 at the Outside of the carrier body 46 serve the air flow for heat dissipation.

Overall, the lighting module 42 two lighting circuits each with one of the control devices 52 and the corresponding associated light emitting diodes 48 on. The lighting circuits can be controlled separately, for example, switched on or off, or adjusted in their luminous power. The light-emitting diodes 48 Each of the lighting circuits is evenly distributed over the cooling surface 64 on the outside of the carrier body 46 distributed to allow a uniform light emission.

The two separate operated light circuits can be used, for example, for the realization of a so-called half-night circuit. During a half-night shift, one of the lighting circuits is switched off for part of the night so that the street light 10 is operated with the remaining lighting circuit with a lower energy consumption. Due to the alternating arrangement of the LEDs 48 the two lighting circuits, switching off one of the lighting circuits has no significant effect on the actual spatial radiation characteristics of the lighting module 42 ,

Due to the thermal contact of the heat-generating and heat-conducting components, namely the light-emitting diodes 48 , the electronic components 50 and the tracks 48 with which the cooling surfaces 64 having carrier body 46 and its curved shape, a heat dissipation and thus a thermal management can be improved.

The reflector carrier 44 will be described below on the basis of 9 and 10 explained in more detail. The reflector carrier 44 has approximately the shape of a tub whose inner shape is about the outer shape of the lighting module 42 equivalent. The lighting module 42 is in the reflector carrier 44 hooked.

In its side walls, the reflector carrier 44 two rows each with each 14 reflectors 78 on. The reflectors 78 are, viewed from the outside, concave depressions, whose inner sides each have a reflective surface. At its lowest point, every reflector has 78 a passage for light. Every reflector 78 is a group 76 the light-emitting diodes 48 on the carrier side sections 62 of the carrier body 46 of the lighting module 42 assigned.

In its bottom wall, in the 9 and 10 above or in the foreground, has the reflector support 44 four reflectors 80 in the form of concave depressions with reflective surfaces. Each of the reflectors 42 is one of the rows 70 with light-emitting diodes 48 of the vehicle main section 60 of the carrier body 46 of the lighting module 42 assigned.

With the reflectors 78 and 80 is that of the light emitting diodes 48 emitted light bundled accordingly. In this way, a light emission can be improved.

Instead of the reflectors 78 and 80 It is also possible for lenses or lens arrangements to be provided on a corresponding optical system carrier. Alternatively, corresponding optical systems can be provided on the corresponding designed light emitting diodes or combined with this. In this case, it is possible to dispense with a separate optical system carrier with corresponding optical systems.

At its transverse sides is the reflector carrier 44 closed.

To assemble the lamp 16 becomes the pre-assembled lighting module 42 in which the adjustment components 56 are set for the appropriate purpose, in the reflector carrier 44 built-in. The reflector carrier 44 will be shared with the lighting module 42 in the lamp pan 34 arranged. Subsequently, corresponding electrical connection lines between the connection components 54 and the connection device 40 of the lamp cover 36 connected. Then the lamp cover 36 on the lamp pan 34 put on and tightly glued or welded with this.

The pre-assembled lamp 16 gets into the luminaire housing 12 used. The lamp 16 is done with the lamp pan 34 ahead in the lamp opening 26 hooked. The part of the lamp 16 with the carrier body 46 with the LEDs 48 and the reflector carrier 44 is located outside the luminaire housing 12 , The lamp housing 32 lies with the Auflegerand 38 the lamp pan 34 on the the lamp opening 26 surrounding edge of the bottom wall of the lower shell 18 on.

Subsequently, the corresponding locking elements 28 the lower housing pan 18 locked and the lamp 16 in the luminaire housing 12 fixed. Finally, the upper housing tray 20 on the lower housing tray 18 set and fixed with the appropriate fasteners.

Before inserting the lamp 16 in the luminaire housing 12 or after insertion and before closing the upper shell 20 can be a preset of the lamp 16 at the connection device 40 be made. For example, when using the street light 10 in a region in which a lower luminous power is required at night, for example, in a side street or an avenue, a corresponding light output can be reduced.
