Definitions

• Such lighting devices are known from EP-B-0 658 655 and PCT/NL99/00680. Such known lighting devices are provided with lighting elements which lay firmly locked in the material, in general concrete, of the construction element. The material of the construction element is in general cast around the lighting element. After curing the lighting element is anchored in the construction element. The object of these lighting devices is to provide clearly visible road marks at high-risk junctions whereby an active lighting increases the road safety and the liveableness in traffic.
• the space between the lighting element and the construction element is filled with a preferably elastic filling, for example a silicon material or a similar hardening joining material, whereby through simply squirting up or filling up the gap a detachable weak junction between the lighting element and the construction element is obtained.
• a preferably elastic filling for example a silicon material or a similar hardening joining material
• the penetration of fluid and water in the lighting element is hereby minimalized.
• a clamping element is provided to the outline of the lighting element, which clamping element is for example formed out of laminated suspension springs.
• a similar clamping element sets the outline of the lighting element variably. Via a variable outline it is thus possible to simply fill the gap between the lighting element and the construction element.
• a simple manual manipulation of the clamping element results in an increase or decrease of the diameter of the lighting element.
• a similar filling is also advantageous for vandalism prevention purposes because no joining means are visible anymore, unlike the screws in NL 7403905.
• Another preferred embodiment is to provide the lighting element with a separate housing.
• a separate housing which is placed independently of the lighting element, can be supplied fixed in the construction element whereby the lighting element then can be detachably provided in the housing.
• the housing can for example be supplied with a wedge- shaped junction part.
• a second aspect of the invention relates to a lighting element that is suitable to be applied in a lighting device according to the invention comprising a number of light-emitting diodes (LED's) that are provided on a fixing plate, which is completely cast in a light- conducting massive material, whereby the fixing plate is light-reflecting.
• LED's light-emitting diodes
• the use of such a fixing plate also supplies even when the lighting device is not electrically active, a light- reflecting effect.
• screw elements can be supplied at the back of the lighting element to make the attachment with a fixed assembled attachment element possible.
• sideway screw elements can optionally be attached to the lighting element.
• the screw element lays in the diameter of the lighting element.
• a third aspect according to the invention relates to a method for applying an active lighting-element in a lighting device comprising the steps of : - the drilling of a first free space in the to the road-way turned side with such a diameter for the detachable housing of a lighting element, the drilling of a second opening on the from the road-way averted side, which second opening has a diameter suitable for conducting the electronic cables of the lighting elements, whereby the passage of the second opening on one hand ends up at the groove and on the other hand at the passage of the first opening, and the detachable attaching of the lighting element in the lighting device.

• Figure 8 is a cross-sectional view of yet another preferred embodiment of the lighting element according to the invention.
• Figure 1 shows a roundabout 1 by which the road-way 2 and the shrubbery 3 is bounded by means of a traffic controller 4.
• the traffic controller 4 comprises a number of construction elements 5 in which three lighting elements 6 are incorporated.
• the lighting elements 6 increase the road safety and this in an active way because the lighting elements 6 not only reflect light but also actively emit light.
• lighting element 6 is assimilated standing in the free space 7, in which a first opening via a passage 8 makes a junction with a second opening 9.
• Such a passage makes the parallel junction 11 ( Figure 6) of the junction cables 10 of the lighting elements 6 possible.
• the construction element 5 has an enlarged basis and is in general manufactured out of reinforced construction material, for example concrete and preferably out of sliding concrete.
• a filling for example made of polyurethane assembly foam is put in.
• the use of such a foam allows when the lighting element 6 is damaged and non-active, to separately and simply replace the lighting element without needing to replace the entire composition of the construction element and lighting element.
• the play between the junction cable 10 and the passage 8 is filled with such a filling 12.
• a suitable placing of the lighting element and a dust and water free closure is the result.
• the filling of the gap between the lighting element 6 and the construction element 5 can also be obtained by a separate housing 13 (Figure 8) which is for example in cross- section partially wedge-shaped.
• a separate housing 13 Figure 8 which is for example in cross- section partially wedge-shaped.
• Another embodiment is providing clamping elements 14 ( Figure 7) whereby these clamping elements set the outline and the diameter of the lighting element 6 variably. It goes without saying that either the housing 13, or the lighting element 6 in the housing 13, or both mutually are installed removable.
• FIG. 5 The assembly is shown in cross-sectional view as an example in Figure 5. Via a central internal screw 15 a temporary junction via the support plate 16 and nut 17 is made with a clamping bracket 18 which centers the lighting element 6 in the free space 7. After centering, the filling material 12 is placed in the gap.
• a construction element 5 made of sliding concrete which is provided with a groove 15 which can serve as a cable gutter for the cables 19 is rendered. Possibly the cable gutter can be screened with a screening lath to be installed separately (not shown).

• a junction is established with the junction cable 10.
• the applied light-conducting material is impenetrable for dust, fluid and water vapor and fully encloses the electronic circuit 23, the LED's 21 on the fixing plate and the screw 15.
• the LED's 21 lay more than 5 mm underneath the top layer and are preferably regularly divided over the lighting element 6.
• a black optional protecting layer of varnish covers and protects the back 25 of the lighting element 6 from which the junction wire 10 stretches out.
