Indirect lighting fixture with reflectors
A method and system for adjusting a light source that is capable of displaying light of different colors receives inputs from various sources and provides an output color selection signal. The output color selection signal is applied to the light source to adjust the intensity and color thereof.
1 . An indirect light fixture, disposed to simulate a planar light source, comprising:
(a) a printed circuit board;
(b) a reflective material, affixed to said printed circuit board, forming a substantially planar reflective surface; and
(c) a plurality of high intensity LED assemblies, each assembly including:
(i) a LED, disposed to emit light;
(ii) a LED housing, attached to said printed circuit board; and
(iii) a reverse paraboloidic reflector, secured in proximal relation from said LED assembly such that said reverse paraboloidic reflector blocks direct light from said LED to a viewer, at any angle;
wherein resulting combination said planar reflective surface and said reverse paraboloidic reflector effectively distributes light emitted from said LED over a greater surface area than without said combination.
2 . The indirect light fixture of claim 1 , further including mounting wires adapted to secure said paraboloidic reflector in proximal relation from said LED assembly.
3 . The indirect light fixture of claim 1 , wherein said reflective material is a reflective foil.
4 . The indirect light fixture of claim 1 , wherein said LED assemblies are attached to a ceiling tile.
5 . The indirect light fixture of claim 4 , wherein said LED assemblies are arranged in a grid pattern.
6 . The indirect light fixture of claim 4 , wherein:
said printed circuit board is plurality of printed circuit boards, each formed in the shape of a strip;
said strip containing a plurality of said LED assemblies;
said plurality of strips mounted in rows.
7 . An indirect light fixture, disposed to simulate a planar light source, comprising:
(a) a printed circuit board;
(b) a reflective material, affixed to said printed circuit board, forming a substantially planar reflective surface; and
(c) a plurality of high intensity LED assemblies, each assembly including:
(i) a LED, disposed to emit light;
(ii) a LED housing, attached to said printed circuit board; and
(iii) a reflector, with a shape, said reflector shape selected from a group consisting of a cone, a pyramid, or a multifaceted geometric shape that approximates a cone, secured in proximal relation from said LED assembly such that said reflector blocks direct light from said LED to a viewer, at any angle;
wherein resulting combination said planar reflective surface and said reflector effectively distributes light emitted from said LED over a greater surface area than without said combination.
8 . The indirect light fixture of claim 7 , further including mounting wires adapted to secure said reflector in proximal relation from said LED assembly.
9 . The indirect light fixture of claim 7 , wherein said reflective material is a reflective foil.
10 . The indirect light fixture of claim 7 , wherein said LED assemblies are attached to a ceiling tile.
11 . The indirect light fixture of claim 10 , wherein said LED assemblies are arranged in a grid pattern
12 . The indirect light fixture of claim 10 , wherein:
said printed circuit board is plurality of printed circuit boards, each formed in the shape of a strip;
said strip containing a plurality of said LED assemblies;
said plurality of strips mounted in rows.
13 . An indirect light fixture, disposed to simulate a planar light source, comprising:
(a) a printed circuit board;
(b) a reflective material, affixed to said printed circuit board, forming a substantially planar reflective surface; and
(c) a plurality of high intensity LED assemblies, each assembly including:
(i) a LED, disposed to emit light;
(ii) a LED housing, attached to said printed circuit board; and
(iii) a convex reflector, secured in proximal relation from said LED assembly such that said convex reflector blocks direct light from said LED to a viewer, at any angle;
wherein resulting combination said planar reflective surface and said convex reflector effectively distributes light emitted from said LED over a greater surface area than without said combination.
14 . The indirect light fixture of claim 13 , further including mounting wires adapted to secure said convex reflector in proximal relation from said LED assembly.
15 . The indirect light fixture of claim 13 , wherein said reflective material is a reflective foil.
16 . The indirect light fixture of claim 13 , wherein said LED assemblies are attached to a ceiling tile.
17 . The indirect light fixture of claim 16 , wherein said LED assemblies are arranged in a grid pattern.
18 . The indirect light fixture of claim 16 , wherein:
said printed circuit board is plurality of printed circuit boards, each formed in the shape of a strip;
said strip containing a plurality of said LED assemblies;
said plurality of strips mounted in rows.
