- a disadvantage of such lamp arrangements is that the heat-sensitive light-emitting diodes are arranged in a thermally highly loaded region of electrode coils arranged in end sections of the discharge tubes and heated to generate free electrons. Due to the thermal load of the LEDs, the light emission decreases with increasing temperature of the discharge tubes. Furthermore, the thermal load leads to a reduced life of the LEDs and after reaching the maximum operating temperature to the failure.
- the thermal load of the light-emitting diodes is further enhanced by an enveloping piston used in the prior art according to WO 02/062106 A1 due to the reduced heat radiation of the lamp arrangement and the thereby increasing internal temperature of the enveloping piston.

- the cooling zones are formed in conventional compact fluorescent lamps in the region of the tube bends of the discharge tubes, as they are furthest away from the heated electrode filaments.
- the lamp arrangement has at least one extender for receiving the light-emitting diode arrangement, which is arranged such that the light-emitting diodes are arranged substantially in the region of the cooling zones of the compact fluorescent lamp. It has proven particularly advantageous if the extender extends along a longitudinal axis of the base and the light-emitting diode arrangement is arranged on at least one end face of the extender.
- the extender is arranged on the outer surface of a base cover of the base or inserted into a receptacle of the base cover.
- the light-emitting diode arrangement has at least three light-emitting diodes which are arranged on the end faces of the extender side delimiting corner regions.
- the lamp arrangement has two diametrically opposed extenders, which are arranged substantially offset by approximately 90 ° to a plane of the longitudinal axes of longitudinal tube sections of the discharge vessel.
- the lamp assembly preferably has an electronically or manually operable switch for switching between mains operation and energy storage operation of the lamps.
- the lamp arrangement has at least one light sensor for detecting the incident light and control electronics for driving the alternative light source and / or the low-pressure discharge lamp.
- the lamp arrangement is suitable for autonomous lighting tasks, for example in the outdoor lighting area.

- a threaded portion 26 is formed on the base 12.
- the cooling zones 30 are formed in the illustrated compact fluorescent lamp 2 in the region of the tube bends of the discharge tubes 14, 15, 16, since they are farthest from the heated electrode filaments.
- the effect the cooling zones 30 is additionally improved by the geometric design of the discharge tubes 14, 15, 16 with small radii of the tube bends, where the excess mercury of the lamp filling can condense and an optimal temperature of about 30 to 5O 0 C.
- the temperature in the region of the cooling zones 30 of the discharge vessel 8 in relation to the end sections of the discharge tubes 14, 15, 16 is minimal and the light-emitting diode 28 is only slightly thermally loaded.
- This solution enables an improved compared to the prior art light emission with extended life of the light emitting diode 28.
- the cooling zones 30 of the discharge vessel 8 the high lamp temperatures in the area of the electrode coils continue to be compensated, reaches an optimal mercury vapor pressure in the discharge vessel 8 and thereby the light emission of the compact - Fluorescent lamp 2 improved.
- the light emitting diode 28 has an integrated lens optics (not shown). In the shown
