A reflecting arrangement is located above the plane and reflects the light emitted by the diodes in a sidewards direction. A surrounding reflecting arrangement can be provided around the diodes and an additional reflecting arrangement in form of a layer on the plane may also be utilized. This Abstract is not intended to define the invention disclosed in the specification, nor intended to limit the scope of the invention in any way.
CROSS REFERENCE TO RELATED APPLICATIONS This application claims priority under 35 U.S.C. � 119 of European Patent Application No. 04 024 156.4 filed on Oct. 11, 2004, the disclosure of which is expressly incorporated by reference herein in its entirety.
Agencies such as, e.g., EASA (European Aviation Safety Agency) or FAR (Federal Aviation Regulations) have international regulations for airborne aircraft with fixed wings or rotary wings (airplanes or helicopters) which require an external lighting which, in addition to the position lights, requires so called anti collision lights which must radiate by day and by night above a certain minimal intensity indicated in Candela. According to EASA, the anti collision lights must, e.g. radiate in red (�aviation red�) or in white (�aviation white�) with a predetermined intensity and color, and also within a given solid angle.
SUMMARY OF THE INVENTION The present invention aims to provide a LED anti collision light with a compact design and providing ease of manufacturing.
A first embodiment of an anti collision light for an aircraft (hereinafter called ACL) is shown in FIGS. 1�10. FIGS. 1�3 show the ACL 1 from the outside in different views wherein it can be seen that the ACL 1 comprises a socket parts 4 and 5, a main housing 3, and a transparent cover 2. Arranged within the transparent cover 2 is a module 8 that includes light emitting diodes 13 (not shown in FIG. 1�3). The exploded view of FIG. 4 shows the same elements and exposes the module 8 arranged on the housing part 3 and covered by the transparent cover 2. A ring shaped collar 9 is utilized to mount the cover 2 to the housing 3. The module 8 is mounted to the housing 3 as will be shown later in FIG. 8. Also arranged within the housing 3 are the electronic components for generating the low voltage �dc� current for feeding and/or powering the light emitting diodes 13 with power from a higher voltage �dc� or �ac� current. These components can be arranged on a circuit board 6. The housing 3 is closed by a lower part 4 which can belong to the socket part 5 or which can be part of the housing 3 itself. The socket parts 4 and 5 can be a screw type socket as shown or can be of any other type for mounting the ACL 1 to the aircraft as known to the man skilled in the art.
FIGS. 5, 6 and 7 show the module 8 in a preferred special embodiment. In the sideview of FIG. 5, a plane 12 is shown on which the light emitting diodes 13 are arranged as can be seen in FIG. 8. A reflecting arrangement 16 has, in this case, the form of a parabolic reflector having a circular upper rim 16′ and a lower rim 16″. The reflector 16 reflects light that is emitted by light emitting diodes 13 upwardly towards the reflecting arrangement 16 in a sidewise manner as indicated by arrows A in FIG. 5. A number of light emitting diodes 13 are arranged, preferably in a circle, around the lower rim 16″ of reflecting arrangement 16. As a result, the spatial light emitting characteristics of the ACL 1 achieves 360� of reflected light. The plane 12 and the reflecting arrangement 16 are preferably arranged on a support 11. Another plane 22 can be arranged on the same support 11 or on another support. The other plane 22 faces with its back to the back of plane 12 (i.e., in the opposite direction) and carries a number of light emitting diodes 23 as well. Another reflecting arrangement 26 is arranged above the other plane 22. Above in this case means that the light emitted by the light emitting diodes 23 on plane 22 are emitted as well away from the plane 22 mostly in a perpendicular direction to the plane 22 and then falls on the reflecting arrangement 26 with upper rim 26′ and lower rim 26″. The reflected light is directed sidewardly as is shown, for example, for a single light beam with arrows B in the same manner as for the plane 12 with arrows A. So even if the reflecting arrangement 26 is below plane 22 in the drawing, it is meant and indicated here (in view of the direction of the light) that reflecting arrangement 26 is arranged above plane 22.
FIGS. 11 and 12 show another embodiment of a module 8 similar to the one described above but which does not emit light around a full circle (360�). Instead, the support 11 preferably has an approximately U-shape rim. The same holds true for circuit boards 50 with their U-shaped rims 32 and 42 and for the arrangement of the light emitting diodes. Surrounding reflecting arrangements 54 and 64, which also include holes 55, are preferably present as well as are additional reflecting arrangements in form of the layer on the planes/circuit boards. The main reflecting arrangements 36 and 46 with their rims 38 and 48 and the U-shaped rims 49 are preferably shaped in a parabolic way as well in order to direct light emitted by the diodes in a sidewards manner as explained above. The module 8 of this kind which is U-shaped, or shaped like a horseshoe, can also be arranged in a bracket 60 as shown in FIGS. 11 and 12. In this case as well, the module uses a housing which is not shown in the Figures and a clear cover which protects the module.
