More specifically, the light channel 35 has a first portion 35a, which at ⁇ closing to the window 34 partially by the Lichtleit ⁇ element 4 (in particular its Outside 4b) and partly is formed or limited by the ring cover 6 (in particular its inner wall 8).
- the first portion 35a leads from the window 34 vertically down to a second portion 35b.
- the second section 35b extends in the volume covered by the ring cover 6 or in the interior of the ring cover 6, in which the light sensor 31 is accommodated.
- the second section 35b connects the first Ab ⁇ section 35a optically 31 with the light sensor in order to avoid a loss of light, for example by absorption, to which the first portion 35a and / or the second portion 35b of the light channel 35 walls defining reflective latests ⁇ be stopped.
- the outer side for example, completely or at least in the region of the light channel 35 ⁇ reflective 4b of the light guide 4, in particular reflective, be designed.
- the inner wall 8 of the ring cover 6 can be designed to be reflective, in particular reflective, entirely or at least in the region of the light channel 35.
- the light-guiding element 36 like the light- guiding element 4, is provided on its inside 36a with a wave-like structure for improved light mixing.
- the hollow cylindrical light-guiding element 36 is now constructed in two parts from a brighter-illustrated first half 37 and a darker-illustrated second half 38.
- the two halves 37,38 are engaged at their adjoining or adjacent edges each case by means of a latching closure or a Rastverbin ⁇ dung. 39
- a light-guiding element 36 with a comparatively complex surface can also be produced easily and also assembled easily.
- the window is not shown here for the sake of simplicity.
- the lower edge 32 may have at least one breakout 40 to avoid problems due to creepage distances.
- 7 shows a light guide 41 according to a third From ⁇ guide die.
- the light guide 41 has on its inner side 36 a, the wave-like structure and is composed of two parts of a first half 42 and a second half 43.
- the two halves 42, 43 are also latched at their adjacent or adjacent edges by means of a latching connection 39.
- the light-guiding element 41 now has a hollow-cylindrical basic body made of a transparent, in particular transparent, material, eg PMMA or glass.
- the main body is covered on its outer side 41b (alternatively or additionally on its inner side 41a) with an opaque, in particular reflective, layer (eg a BEF layer).
- the window 34 is formed by a recess in the opaque layer, which here releases the latching connection 39.
- the window 34 is thus formed by or on the latching connection 39.
