On the other hand, the edges of the thermal passage openings 30, which are bent over towards the holding element 50, with the above-described webs 61 of the holding element 50, can form a preferably continuous and closed-edge cooling air channel.
• the funnel-like downward widening side walls 13 of the light housing 10 each form laterally below the adjacent through openings 30 an air inflow area and thus contribute to the formation of an overall air inflow area that widens away from the lighting means 130, so that an efficient flow of cooling air is made possible despite the large area in relation to the overall height of the lamp 1.

Only the two receiving areas 20 and 25 can be seen, which are enclosed in a ring-like manner by the wave-like sealing structures 35, although the above-mentioned transverse channel section 37 interrupts both ring-like structures in order to connect the two receiving areas 20 and 25 to one another.

• the additional material 41 also fills the channel from section 37 completely and accordingly also contributes to sealing. It is decisive that ultimately - as can be seen in FIG. 19 - both receiving areas 20, 25 of the lamp housing 10 are completely enclosed in a ring-like manner by a seal 40 and can accordingly interact in the manner described above with the holding element 50 or the cover 70 or 80 in order to enclose the receiving spaces A and B in a sealing manner. However, both areas A and B are then connected to one another via the hollow cylinder 101 of the channel-forming component 100 in such a way that a supply cable can still be passed through even after the sealing material 40 has been applied. Again, the assembly of the luminaire 1 is thereby made easier overall, the luminaire components 120, 130 being reliably and securely protected from external influences in spite of everything. A corresponding connection could also be created with the aid of the component 100 between the two receiving spaces B for the lighting means 130, provided that a cable connection is selected

• the lamp 200 has only a single sealed connection for an external power supply cable. This requires that the two receiving areas for the operating devices must in turn be connected to one another in such a way that a connection cable can be laid. Accordingly, the use of a recess 205 together with the channel-forming component 100 explained with reference to FIGS. 15 to 19, which connects the two areas of the luminaire 200 located one behind the other in the longitudinal direction, is again preferred to connect these two areas.
