Claim 8

In a light fixture having a light source and a reflector with a plurality of reflecting surfaces, a first group of said surfaces toward the center of the reflector reflecting light from said source at low angles in directions substantially focally from the fixture and a second group of said surfaces relatively distant from the center of the reflector reflecting light from said source at substantially high angles to the focal direction, the improvement comprising light diffusing means added to said first group of reflecting surfaces, and light specular means added to said second group of reflecting surfaces.

Claim 9

In a light fixture having a light source and a reflector with a plurality of reflecting surfaces, a first group of said surfaces toward the center of the reflector reflecting light from said source at low angles in directions substantially focally from the fixture and a second group of said surfaces relatively distant from the center of the reflector reflecting light from said source at substantially high angles to the focal direction, the improvement comprising light diffusing means added to said first group of reflecting surfaces, and light specular means added to said second group of reflecting surfaces.

Claim 10

Claim 11

The light reflector in accordance with claim 7, and including hammertoning said second group of reflecting surfaces for increasing the high angle reflections therefrom.

Claim 14

The method in accordance with claim 10, wherein the low reflecting angle surfaces are covered with a substance having light diffusing characteristics.

Claim 15

The method in accordance with claim 11, wherein said substance is white paint.

Claim 16

The method in accordance with claim 10, wherein said high reflecting angle surfaces are treated by hammertoning.

Claim 17

The method in accordance with claim 10, wherein said high reflecting angle surfaces are covered by a covering treated by hammertoning.

Claim 20

The method of making a light reflector in accordance with claim 15, wherein the specular material is hammertoned.

Claim 21

In a light fixture having a light source and a reflector with a plurality of reflecting surfaces, a first group of said surfaces reflecting light from said source at low angles in directions substantially focally from the fixture and a second group of said surfaces reflecting light from said source at substantially high angles to the focal direction, the improvement comprising said first group of surfaces being wider toward the center of the reflector and narrowing toward the periphery, said second group of surfaces being respectively at least partially between said first group of surfaces, said first group of surfaces reflecting light in substantially focal directions and being diffusively treated with respect to said second group of surfaces so as to produce a wider reflecting beam spread from the fixture than the reflecting beam spread from a fixture of like reflecting surfaces without any diffusively treated surfaces.

Claim 22

In a light fixture having a light source and a reflector with a plurality of reflecting surfaces, a first group of said surfaces reflecting light from said source at low angles in directions substantially focally from the fixture and a second group of said surfaces reflecting light from said source at substantially high angles to the focal direction, the improvement comprising said first group of surfaces being wider toward the center of the reflector and narrowing toward the periphery, said second group of surfaces being respectively at least partially between said first group of surfaces, said first group of surfaces reflecting light in substantially focal directions and being diffusively treated with respect to said second group of surfaces so as to produce a wider reflecting beam spread from the fixture than the reflecting beam spread from a fixture of like reflecting surfaces without any diffusively treated surfaces.

Claim 23

In a light fixture having a light source and a reflector with a plurality of reflecting surfaces, a first group of said surfaces being wider toward the center of the reflector and narrowing toward the periphery, a second group of surfaces being at least partially respectively between said first group of surfaces, said first group of said surfaces reflecting light from said source at low angles in directions substantially focally from the fixture and said second group of said surfaces reflecting light from said source at substantially high angles to the focal direction, the improvement comprising light diffusing means added to said first group of reflecting surfaces.
