Tessellated bezel luminaires
The present invention relates generally to tessellated bezel light diffusers which act to disperse penumbral light providing more uniform and even illumination. The present invention also relates to luminaires employing an array of light sources with tessellated bezel light diffusers which act to eliminate edge and transition lighting effects providing more uniform and even illumination between LEDs and at the periphery of illuminated zones. The present invention also relates to luminaires employing LED arrays equipped with tessellated bezel light diffusers that provide very uniform illumination zones with more evenly dispersed transitional edge lighting than conventional luminaires.
1. A luminaire with improved light dispersion properties comprising:
a) a plurality of light emitting elements;
b) a a plurality of light shades each positioned adjacent to and surrounding a respective one of said light emitting elements and located about an optical axis perpendicular to said respective one of said light emitting elements;
wherein each one of said light shade features a mounting region located at a first distal edge, a plain light shade region continuous with said mounting region, the plain light shade region being continuous with a bezel region that terminates at a second opposed proximate edge;
wherein said bezel region features an upper surface having at least one tessellated edge; and wherein said tessellated edge provides for a more uniform direct and penumbral light transmission pattern as compared to a non-tessellated edge;
wherein said bezel region features a combination of a tessellated region and a non-tessellated region; and wherein said tessellated region has at least one tessellated pattern and said non-tessellated region is plain.
2. The luminaire of claim 1 , wherein said bezel region features at least one or a plurality of tessellation patterns corresponding to a k-th degree polynomial fit of a shape comprising either said full or partial geometric pattern; and wherein k is an integer between 1 and 5.
3. The luminaire of claim 1 , wherein said bezel region features at least one of a plurality of tessellation patterns corresponding to a n-fractal derivative of said geometric pattern; and wherein n is an integer between 1 and 5.
4. The luminaire of claim 1 , wherein each of said light shades bears at least one portion of the same bezel pattern and wherein each of said bezels is at least partially tessellated.
5. The luminaire of claim 1 , wherein at least one of said light shades bears at least one unique bezel pattern with at least one tessellation pattern differing from the tessellation pattern of an adjacent light shade.
6. The luminaire of claim 1 , wherein at least one of said light shades features an angled bezel region that is at least partially tessellated and is disposed about an optical axis that is not perpendicular to that of said light emitting elements.
7. The luminaire of claim 1 , wherein said light shade has an overall geometry selected from shapes including a circle, ellipse, square, and a rectangle; and wherein said optical axis corresponds to the mean geometric center axis of the selected shape.
8. The luminaire of claim 1 , wherein said light shades do not curve back onto themselves and are at least partially tessellated along a portion of said bezel.
9. The luminaire of claim 1 , wherein two light shades are disposed opposite one another and aligned with respect to a horizontal axis passing through each of said light emitting elements; wherein at least one of said light shades feature at least one partially tessellated edge along a portion of said bezel.
10. A luminaire with improved light dispersion properties comprising:
a) a plurality of light emitting elements;
b) a plurality of light shades each positioned adjacent to and surrounding a respective one of said light emitting elements and located about an optical axis perpendicular to said respective one of said light emitting elements;
wherein each one of said light shade features a mounting region located at a first distal edge, a plain light shade region continuous with said mounting region, the plain light shade region being continuous with a bezel region that terminates at a second opposed proximate edge;
wherein said bezel region features a first upper surface and second lower transition region adjacent to said plain light shade region; wherein said bezel region features a combination of a first opaque and non-light transmitting portion composed of a first material and a second light transmitting portion composed of a second material; wherein said first and second portions create an optical tessellation pattern; and wherein said optical tessellation pattern provides for a more uniform direct and penumbral light transmission pattern as compared to a non-tessellated edge.
11. The luminaire of claim 10 wherein said second light transmitting portion is selected from a second material that is clear, translucent or partially light-transmitting; wherein said first material may either be a different material than said second material, or said second material infused or treated to provide opacity thereto so that the first portion is opaque and non-light transmitting.
