Abstract

An LED architectural luminaire comprising a gull wing reflector, an LED mounting plate and a central lens. The mounting plate is disposed in said reflector and includes a central flat mounting surface flanked by a pair of angled mounting surfaces, each of the mounting surfaces includes a strip of LEDs. The central lens is disposed over and hingeably removably connected to the mounting plate. End caps, light seals, and optional gaskets are disposed on the ends of the luminaire.

Claims

1. An LED architectural luminaire comprising:

a gull wing reflector housing defining a channel;

an LED driver disposed in said channel;

an LED mounting plate disposed above said channel, said LED mounting plate including a flat central mounting surface and a pair of parallel downwardly sloped surfaces;

three LED strips, one disposed on each of a respective mounting surface of said LED mounting plate; and

a central lens member, said central lens member being prismatic and disposed above said LED mounting plate.

2. The luminaire of claim 1 wherein said sloped sides are angled at a slope of about 20°

to 60°

.

3. The luminaire of claim 2, wherein said slope is about 30°

.

4. The luminaire of claim 1, wherein said housing includes a pair of end caps.

5. The luminaire of claim 4, further comprising light seals disposed in an area adjacent said end caps.

6. The luminaire of claim 5, comprising light seals disposed in an area adjacent said end caps and gaskets.
