  • Figures 23 A-F illustrates a lens rim used with the embodiment of the preceding figures.
  • FIG 4 shows the basic components of sports lighting fixture 10 in exploded form.
  • Figures 5 A and B show it in assembled perspective form.
  • Fixture 10 has some similar general components to state-of-the-art sports lighting fixtures, but introduces some different structural components and concepts.
  • Reflector frame 30 (cast aluminum type 413) bolts to lamp cone 40. The frame
  • FIG. 23A for glass lens 32 is removably latched to the front of reflector frame 30.
  • Visor 70 is mountable to the lens frame and extends from the upper front of reflector frame 30 when in place. It includes high reflectivity strips on its interior 72.
  • visor 70 can take different shapes and forms.
  • a first style of visor 7OA (Figure 5A) is shorter and does not extend forwardly and downwardly as much as second visor style 7OB ( Figure 6A). Both have an identical base section ( Figure 13) that extends initially at a less converging angle from reflector frame 30.
  • a distal extension section connects to the base section and angles back inwardly toward the central axis of reflector frame 30.
  • the shorter visor 7OA uses a shorter extension section ( Figure 14) than the longer visor 7OB (see extension of Figure 15).
  • Visor 7OB is useful, for example, when fixture 10 is aimed at angles closer to horizontal. It would block and redirect more light that would otherwise go off the target area, as compared to visor 7OA.
  • Visor 70 As indicated at Figure 4, a visor 70 is attachable to fixture 10. High total reflectivity material is mounted on its inner or downward-facing side 22. Essentially the exterior of visor 70 is a protective cover over the high reflectivity material it supports. Figures 5A and 6A illustrate two general forms visor 70 can take.
  • visor 70 actually is larger in size than many existing visors, and increases the overall size of fixture 10. However, their shape and configuration has been designed to actually decrease wind load by on the order of 40% over conventional fixtures. The length, shape, and edges of visors 70 are designed to improve the EPA of the whole fixture 10. They are cost effective with excellent reflection efficiency.
  • a plurality of side-by-side, high reflectivity or reflectance reflector inserts are riveted or otherwise secured to the inside of base reflector 240 and attached reflector 250.
  • upper and lower rails 254 and 256 can be attached to proximal and distal positions on the inside of visor combination 240/250, and the reflective visors installed into slots 255 and 257 respectively, and then riveted or bolted into place (see openings in rails 254 and 256).
  • One or more radial support brackets 258 can be connected back to front of visor combination 240 and 250 to provide more rigidity for upper and lower visor reflective insert rails 254 and 256. Examples of high reflectivity inserts and materials are discussed in U.S. Patent No. 6,036,338.
  • visor 70 The shape of visor 70 is designed to achieve several functions. First, it supports the highly reflective inserts in a manner that controls spill and glare light. Second, it supports the reflective inserts in a manner which minimizes light loss, and can increase light to the target. Third, its shape minimizes the projected area of the visor and the fixture generally to produce a low coefficient of drag. Fourth, it accomplishes these functions in a relatively low cost but efficient way.
  • the wind drag is reduced on the order of 40% or more.
  • Spill and glare can be controlled with a visor 70, but also with other features disclosed herein, if used (e.g. lower initial output intensity, side shift, reflecting surfaces that highly control direction of light). This can allow cheaper poles to be utilized, which can significantly reduce overall capital cost of a lighting system. Less wind drag means the strength of the pole that elevates the fixtures can be less.
  • Visor 70 can be used even if glare and spill control is not an issue because of improved EPA of the fixture, which can reduce cost of poles. It has excellent efficiency and is relatively low cost. This is especially beneficial for outdoors sports lighting.
  • a prismatic material could be used in the visor opening for different lighting effects.
  • An angled stepped prismatic reflector inside reflector 70 could also be used.
  • Black paint could be used on the opposite sides of the visor reflecting surface for extreme glare and spill light control.
  • the visor, or the whole reflector frame/visor combination could be painted, ornamented, or otherwise configured in the colors of a team or school. Because the reflector frame and visor exteriors are cast, and do not contain the reflecting surface, painting is a more viable option.
  • the method of attaching the reflective strips or other high reflectance surface to the underside of visor 70 can vary, as can the way it is supported.
  • Figures 17-A- C and 19A-C illustrate reflective inserts that can be mounted at opposite sides of reflector 70. They have a shape to match the sides of visor 70. Use of inserts allows for a relatively easy way to add a precise, high reflectivity surface. Change in shape of inserts can alter the way light is controlled so the designer can select them according to need or desire.
  • FIG. 1 The figures illustrate one way of building a visor 70.
  • a sheet aluminum base reflector is attached to a lens rim ( Figure 13).
  • a framework of aluminum or metal pieces is built ( Figures 1 OA-D). Reflective insert strips and pieces are mounted to that framework ( Figures 1 IA-D).
  • the framework with attached reflective inserts is attached to the base reflector ( Figures 12 A-D).
  • a visor extension, either a short aluminum sheet piece or long piece ( Figure 15) is then attached to the sub-assembly of Figures 12A-D.
