The fixture of claim 1 , wherein each of the plurality of panels are set at a first angle along a vertical plane bisecting the support plate and a second angle along a lateral plane extending from a side of the support plate to a front of the support plate so as to produce any of IESNA-specified Type I, Type II, Type III and Type IV roadway illumination patterns.
12. The fixture of claim 1 , further comprising:
a hinge mount assembly attaching each panel to the support plate, the hinge mount assembly enabling a given panel to be rotated in at least two dimensions.
13. The fixture of claim 1 , wherein the panels with LED arrays thereon are configured to provide a total light output of at least 8000 lumens.
14. A LED lighting fixture, comprising:
a support plate, and
a plurality of panels connected to the support plate, each panel having an array of LEDs mounted to a planar surface thereof, each of the panels rotatable in at least two dimensions.
15. The fixture of claim 14 , wherein the plurality of panels include a first pair of front panels and a second pair of rear panels, the front and rear panels individually adjustable to create a desired illumination pattern.
16. The fixture of claim 15 , wherein the LED arrays on the front panels are fitted with secondary optics and the LED arrays on the rear panels have no optics.
17. The fixture of claim 14 , wherein each of the plurality of panels are set at a first angle along a vertical plane bisecting the support plate and a second angle along a lateral plane extending from a side of the support plate to a front of the support plate so as to produce any of IESNA-specified Type I, Type II, Type III and Type IV roadway illumination patterns.
18. The fixture of claim 14 , further comprising:
a hinge mount assembly attaching each panel to the support plate, the hinge mount assembly enabling a given panel to be rotated in at least two dimensions.
19. The fixture of claim 14 , wherein the panels with LED arrays thereon are configured to provide a total light output of at least 8000 lumens.
20. The fixture of claim 14 , further comprising:
a power supply attached to the support plate for driving the LED arrays.
21. A LED lighting fixture, comprising:
a support plate,
a first pair of front panels,
a second pair of rear panels, each of the front and rear panels connected to the support plate and having an array of LEDs mounted to a planar surface thereof, one or more of the front and rear panels individually adjustable to create a desired illumination pattern, and
a power supply attached to the support plate for driving the LED arrays.
22. The fixture of claim 21 , wherein the LED arrays on the front panels are fitted with secondary optics and the LED arrays on the rear panels have no optics.
23. The fixture of claim 21 , wherein each of the front and rear panels are set at a first angle along a vertical plane bisecting the support plate and a second angle along a lateral plane extending from a side of the support plate to a front of the support plate so as to produce any of IESNA-specified Type I, Type II, Type III and Type IV roadway illumination patterns.
24. The fixture of claim 21 , further comprising:
a hinge mount assembly attaching each panel to the support plate, the hinge mount assembly enabling a given front and rear panel to be rotated in at least two dimensions.
25. The fixture of claim 21 , wherein the front and rear panels with LED arrays thereon are configured to provide a total light output of at least 8000 lumens.
