Abstract
A method, apparatus and system for illuminating a sports field. The method includes identifying fixtures having a likelihood of affecting playability or glare or spill light relative to a point of view on or off the field. The method includes steps to identify such fixtures for the purpose of adding a component which improves playability or decreases glare or spill light for the point of view. A further method does so for multiple points of view relative to the field, whether on or off the field. One component is a long visor that would be added only to identified fixtures.
Claims51
A method of lighting a sports field with a sports lighting system including a plurality of lighting fixtures elevated on a plurality of poles, each fixture having a pre-determined aiming point on the field, comprising:
- a. identifying a point of view on or near the field at or from which increased playability and/or decreased glare or spill light is desired;
- b. identifying one or more poles having fixtures that may affect playability or glare and spill from the point of view by identifying poles having fixtures that are generally within a sector emanating from the point of view;
- c. identifying one or more fixtures of each of said one or more poles that may affect playability or glare and spill for the point of view by identifying aiming points that fall within a sector centered on a line between each said one or more poles identified in step b and the point of view;
- d. including a component to a fixture identified in step c which shields or diminishes light and/or direct view of light from the fixture from the point of view;
- so that one or more said fixtures with said component will increase playability and/or decrease glare or spill light relative to the point of view.

A method of designing the addition of long visors to selected fixtures of a baseball sports lighting system for improving playability and/or glare or spill light control comprising:
- a. identifying if any poles fit within a range of degrees of a line between a home plate and a pitchers mound;
- b. if so, identifying if any aiming points to the field for any fixtures on such a pole fall within a second range of degrees of a line between the pole and home plate;
- c. if so, adding a long visor to the fixture if home plate is greater than a third range of degrees above a line between the fixture and the aiming point;
- d. for each of designated right, center, and left fielder positions on the field, identifying if any poles fit within a fourth range of degrees of a line between each such position and home plate;
- e. if so, identifying if any aiming points to the field for any fixtures on such a pole fall within a fifth range of degrees of a line between the pole and such position;
- f. if so, adding a relatively large visor to the fixture if such position is greater than a sixth range of degrees above a line between the fixture and the aiming point.

A method of lighting a sports field with a sports lighting system including a plurality of lighting fixtures elevated on at least one elevating structure, each light fixture having an aiming point on the field, comprising:
- a. identifying a point of view on or near the field at or from which increased playability and/or decreased glare or spill light is desired;
- b. identifying one or more elevating structures having fixtures that may affect playability or glare and spill from the point of view by identifying elevating structures having fixtures that are generally within a sector emanating from the point of view;
- c. identifying one or more fixtures of each of said one or more elevating structures that may affect playability or glare and spill for the point of view by identifying aiming points that fall within a sector centered on a line between each said one or more elevating structures identified in step b and the point of view;
- d. including a component to a fixture identified in step c which shields or diminishes light and/or direct view of light from the fixture from the point of view;
- so that one or more said fixtures with said component will increase playability and/or decrease glare or spill light relative to the point of view.
