Abstract: A pressure-actuated light device (1) with a holding portion (2) that allows a user to hold the pressure-actuated light device in a user's hand. The pressure-actuated light device comprises a housing (3) which houses a light emitting diode (“LED”) (6) having a cathode (11) and an anode (10) extending from it. The cathode has one end permanently connected to the LED and a second end in constant contact with a negative terminal (8) of a battery (7). The anode has one end permanently connected to the LED and a second end separated from a positive terminal (9) of the battery by a spacer (12) which prevents the anode from making contact with the positive terminal while the device is not in use. When pressure is applied to a button (4) on the housing, the button presses the anode against the positive terminal thereby creating an electrical circuit which activates the LED. The holding portion may take alternative forms, including a fin (13), clip (14), ring (15) or elastomeric loop (16).

Abstract: A method, apparatus and system for illuminating a large area with plural high power lighting fixtures. 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 large area. The method includes steps to identify such fixtures for the purpose of adding a component which improves lighting or decreases glare or spill light for the point of view. A further method does so for multiple points of view relative to the large area, whether on or off the large area. One component is a long visor that would be added only to identify fixtures.

A side of the mezzanine portion and a side of the plate portion corresponding to the opening together form a first slit. The slice-shaped circuit is inserted into the containing space through the first slit and stays between the plate portion and the mezzanine portion.
