Abstract:
The present invention provides a diffuser light blocking device comprising an end cap member ( 820 ) having a pocketing feature ( 821 ) that has a side wall ( 822 ) and an end reflective surface ( 810 ); the pocketing feature's shape corresponds to exterior shape of distal portion ( 830 ) of a diffuser ( 800 ) having a distal end surface ( 801 ); the pocketing feature engages the distal portion; an overlapping section ( 815 ) of the pocketing feature's side wall surrounds the distal portion's side wall ( 802 ) and prevents at least 95% of the light output from the distal portion from escaping out of the to distal portion's side wall; the end reflective surface blocks any forward propagating light output from the distal end surface and returns at least 80% of light coming out of the distal end surface back towards the diffuser; the end cap member is thermally conductive; the end cap member's length ( 831 ) and diameter ( 832 ) provide an exterior surface area that is at least 1,000% of the surface area of the distal end surface; and the device reduces generation of diffuser irradiance hot spots.

Claim (Index 18):
A cylindrical light diffusing device comprising: a fiber having a non-circular fiber core and a diffuser light blocking device wherein:\n a. the non-circular fiber core provides a \u201ctop hat\u201d core irradiance distribution and has a latitudinal cross-sectional shape of a regular polygon; b. a light diffusing section having a diffusing proximal end surface, a diffusing distal end surface, and internal scattering features distributed within the fiber core of the light diffusing section along central axis of the fiber core, wherein the light diffusion section provides a \u201ctop hat\u201d diffusing irradiance distribution, thereby limiting the variation of radially emitted irradiance longitudinally from the light diffusing section to be within +/\u221215% of the average (\u201cI 0 \u201d) optical irradiance; c. the light diffusing section further includes a distal portion and the distal portion includes the diffusing distal end surface; d. the diffuser light blocking device is comprised of an end cap member having a length, a diameter, and a pocketing feature wherein:\n i) the pocketing feature includes a side wall and an end reflective surface; \n ii) shape of the pocketing feature corresponds to exterior shape of the distal portion of the light diffusing section; \n iii) the pocketing features engages the distal portion; \n iv) an overlapping section of the side wall of the pocketing feature surrounds side wall of the distal portion and prevents at least 95% of light output from the distal portion from escaping out of the side wall of the distal portion; \n v) the end reflective surface blocks any forward propagating light output from the diffusing distal end surface and returns at least 80% of light coming out of the diffusing distal end surface back towards the diffusing section; \n vi) the end cap member is thermally conductive allowing heat generated by absorption of the light output from the distal portion to be dispersed throughout the end cap member; \n vii) the length and the diameter of the end cap member provide an exterior surface area that is at least 1,000% of surface area of diffusing distal end surface; and \n viii) the diffuser light blocking device reduces creation of a diffuser irradiance hot spot.
