directs more light to the street below. The count in
interference reads as follows:
Count 1
For use in an outdoor pole mounted lighting fixture
having a head fixture housing bearing a depending light
source, the improvement comprising:
an integral unitary reflector spun from aluminum;
a side member of said reflector forming a light
impermeable member of generally parabolic configuration having
a circular cross section tapering inwardly toward an open top
end containing said light source and directing light from said
light source downwardly at a lower open end;
a connection integral with and extending adjacent
said open top end of said side member for receiving said light
source therein and being complementary to a lower end of said
head to prevent the upward passage of light from said light
source;
a matt-like finish on an interior surface of said
reflector providing uniformity of spread and distribution of
light;
said interior surface being of such a configuration
as to reflect light generally downwardly with a substantially
90E cutoff at said lower open end of said side member avoiding
directing light at an angle above the horizontal;
said bottom of said reflector being entirely open to
the atmosphere and devoid of any refractor so that said light
is directed generally downwardly entirely by said interior
surface of said reflector; and
