Beam adjustment mechanism for an LED light fixture

A beam adjustment mechanism for a light fixture includes a frame assembly having an aperture substantially within the center thereof. Multiple peripheral lighting units engage the sides of the frame assembly. Each lighting unit includes an LED, a heat sink, and a reflector member. A central connecting member and/or a central lighting unit is at least partially surrounded by the peripheral lighting units. The central connecting member and/or central lighting unit is hingedly connected to at least one of the peripheral lighting units. An adjustment shaft extends through and is moveably engaged with the aperture of the frame assembly. Movement of the adjustment shaft relative to the aperture exerts a force on the central connecting member and/or central lighting unit, which causes the hingedly connected peripheral lighting units to pivot relative to the central connecting member and/or central lighting unit.
