Patent ID: 8152347

Claim:
A lighting apparatus for producing a high intensity line of light, said lighting apparatus comprising: an elongated support member having formed thereon a linear array of regularly spaced LED modules each of which comprises one or more LED emitting areas having a predetermined spectral output that is emitted over a predetermined solid angle; an array of spaced apart non-imaging concentrators the individual non-imaging concentrators of which are optically coupled in one-to-one correspondence with said regularly spaced LED modules, each non-imaging concentrator in said array of non-imaging concentrators having entrance and exit apertures and operating to collect radiation emitted by each of said LED modules and to re-emit substantially all of said collected radiation as a diverging beam having a solid angle smaller than said predetermined solid angle over which radiation is emitted by each of said LED modules where said diverging beam is spatially and spectrally uniform in the near field of said exit aperture and propagates in a direction along an optical axis of said apparatus with controlled angular divergence in mutually orthogonal planes; and an elongated cylindrical lens positioned to receive radiation emerging from said exit apertures and converge it to a bright line of light forward of said apparatus.
