Coupling element for elongate lamps and illumination system having this coupling element
View Patent ↗A coupling element ( 2 ) is proposed for the combining of at least two elongate lamps with in each case two ends. For this purpose, the coupling element ( 2 ) has a continuous receptacle area which is provided for receiving an end of each lamp. The receptacle area comprises a reflector ( 6 ) in order to reduce the luminance decrease in the region between the lamp ends. With one or a plurality of coupling elements according to the invention in conjunction with two or more elongate lamps, illumination systems having different luminous lengths can be realized in a modular manner.
1. A coupling element for combining at least two elongate lamps, the first lamp and the second lamp each having a respective exterior wall and a respective end, the coupling element having an interior wall defining a receptacle volume having a first region conforming to the exterior wall of the first lamp adjacent the end of the first lamp; and having a second region conforming to the exterior wall of the second lamp adjacent the end of the second lamp; the coupling element to retain the end of the first lamp end adjacent the end of the second lamp; wherein the first region further includes a light reflective surface facing the end of the first lamp and the second region further includes a light reflective surface facing the end of the second lamp; the receptacle further defining a light transmissive aperture commonly adjacent to the end of the first lamp and to the end of the second lamp receiving light from the first region and the second region.
2. The coupling element as claimed in claim 1 , wherein the end of the first lamp includes at least one electrical input for the first lamp, the end of the second lamp includes at least one electrical input for the second lamp and the coupling element includes an electrical connection electrically connecting the electrical input of the first lamp to the electrical input of the second lamp.
3. An illumination system comprising:
a first lamp and a second lamp, each lamp having a respective exterior wall and a respective end, and
a coupling element having an interior wall defining a receptacle volume having a first region conforming to the exterior wall of the first lamp adjacent the end of the first lamp; and having a second region conforming to the exterior wall of the second lamp adjacent the end of the second lamp; the coupling element retaining the end of the first lamp end adjacent the end of the second lamp; wherein the first region further includes a light reflective surface facing the end of the first lamp and the second region further includes a light reflective surface facing the end of the second lamp; the receptacle further defining a light transmissive aperture commonly adjacent to the end of the first lamp and to the end of the second lamp receiving light from the first region and the second region.
