- the invention relates to an underfloor light for signaling and / or marking purposes with a housing which is placed in a traffic area, e.g. a road, airport taxi, take-off and landing runway or the like is embedded, a housing cover, by means of which the housing embedded in the traffic area can be closed on its upper side, which can be detachably connected to the housing, and the at least one Has light outlet opening, and a lamp which is arranged in the housing and can be emitted by means of the light through the light outlet opening of the housing cover.
- a traffic area e.g. a road, airport taxi, take-off and landing runway or the like
- a housing cover by means of which the housing embedded in the traffic area can be closed on its upper side, which can be detachably connected to the housing, and the at least one Has light outlet opening, and a lamp which is arranged in the housing and can be emitted by means of the light through the light outlet opening of the housing cover.
- underfloor lights of this type in which LED (light-emitting diodes) are used as the illuminant, the amount of heat generated during operation of the illuminant is usually converted by convection into a gas, which is often air;
- the illuminant is assigned a heat sink, from which the amount of heat generated during operation of the illuminant is released to the gas or air by convection. Because of the limited spatial conditions prevailing in underfloor fires, underfloor fires equipped with a heat sink with a small thermal resistance have a total thermal resistance of typically more than 30 K / W power loss.
- thermal resistance between the barrier layer of the LED and the PC plate of more than 150 K / W. In some automated applications, thermal resistance in the order of about 70 K / W is achieved.

- the required light emission powers can be achieved with just a single power LED.
- a maximum of six power LEDs per light outlet opening should expediently be provided as the illuminant.
- a collimator element is assigned to the at least one power LED.
- This collimator element can be used to emit the light radiation directly through the radiation window; alternatively, the light can be emitted by means of the collimator element after a previous reflection on a radiation shape or deflection mirror.
- the desired distribution of light radiation can be achieved by using collimators, lenses, prisms, diffractors and / or mirrors.
- the heat-conducting bridge between the illuminant and the housing cover can be realized in a structurally and technically inexpensive manner if the at least one power LED sits with its carrier plate on a base plate which is attached to and with at least one inner cover part connected to the underside of the housing cover forms the thermal bridge to the housing cover and thus to the housing.
- the heat-conducting bridge is advantageously formed by the base plate and two cover inner parts, which are arranged on both sides of the support plate and are connected to the underside of the housing cover.
- the two inner parts of the cover can be arranged on the end sections of the base plate, each inner part of the cover advantageously lying flat against the base plate and flat against the underside of the housing cover. > c ⁇ V> IV) h- 1 P »

- the underfloor light 1 is used for signaling and / or marking purposes.
- the housing 2 of the underfloor light 1 can be closed by means of a housing cover 4, which can be detachably connected to the housing 2, for example by means of screw connections 5.
- the housing cover 4 is only slightly, eg less than 13 mm in front of the traffic area.
- the housing 2 is either directly surrounded by the material forming the traffic area 3, or between the housing 2 and the material forming the actual traffic area 3, thermally conductive building materials, such as epoxy or polyester-filled mortar, are provided.
- a line (power) LED 6 is provided as the illuminant within the housing 2.
- This power LED 6 has a maximum light output power at a through current of approx. 700 to 750 A, as can be seen from FIGURE 11, which shows the light output power as a function of the current intensity for a power LED and for a conventional 5 mm LED ,
- the power LED 6 sits on a carrier plate 7, which in turn, as can best be seen in FIG. 5, is connected to a base plate 9 by suitable connecting means 8.
- the carrier plate 7 of the power LED 6 and the base plate 9 lie flat against one another.
- the total thermal resistance between the barrier layer of the power LED 6 and the base plate 9 is approximately 11 K / W.
- FIG. 11 shows the corresponding values of a customary 5 mm LED, in which there is a thermal resistance of approximately 220 K / W.
- the power LED 6 is assigned a collimator element 10, by means of which the light output of the power LED 6 can be optimized.
- the light emitted by the power LED 6 comes out of the collimator element 10 into an optical unit 11, which exits the emitted light through a light exit opening 12 provided in the housing cover 4.
- the design of the light beam emitted by the underfloor light 1 depends, among other things, on how the optics unit 11 is configured, which lenses, prisms, diffractors, mirrors and the like are adapted according to the desired type of light radiation. can have.
- the collimator member 10 is held by means of a lens holder 13, which in turn is connected by means of suitable connecting members 14 to strongly thermally conductive spacers, for example metallic polygonal sleeves 15, protruding from the base plate 9 on both sides of the carrier plate 7.
- suitable connecting members 14 to strongly thermally conductive spacers, for example metallic polygonal sleeves 15, protruding from the base plate 9 on both sides of the carrier plate 7.
- a shutter 16 is arranged on the side of the lens holder 13 facing away from the collimator member 10.
- the configuration of the assembly from base plate 9, carrier plate 7, power LED 6, polygonal sleeves 15, collimator member 10, lens holder 13 and shutter or shutter 16 can best be seen in FIGS. 5 to 7.
- the base plate 9 is, as can best be seen from FIG. 4, attached to a cover inner part 17, 18 at its two lateral end sections.
- the two inner cover parts 17, 18 are designed in the same way, so that only the inner cover part 17 is described below.
- the inner cover part 17 is, as can best be seen from an overview of FIGS. 2 to 4, connected flat to the underside 19 of the housing cover 4. Accordingly, the inner cover part 17 lies flat against the end section of the base plate 9.
- the mutually assigned contact surfaces on the inner side of the cover and base plate and the mutually associated contact surfaces on the inner side of the cover and the cover are designed to be metallically smooth in order to ensure undisturbed heat transfer between the base plate 9 and the inner cover part 17 or the inner cover part 17 and the housing cover 4.
- the base plate 9 and the inner cover part 17 or the inner cover part 18 form a heat-conducting bridge between the power LED or its carrier plate 7 and the housing cover 4.
