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).

At least one biasing member biases an outer side of the first heat sink member and an outer side of the second heat sink member into contact with an inner side of the housing. Heat from the at least one LED is transferred through the heat sink assembly to the housing, where it is dissipated into the air.

Abstract: A lighting fixture having a housing with a main body, and a primary light source disposed beneath a cover secured thereto with a latching mechanism. The light fixture may include a reflector suspended above the main body on a pair of struts. The latching mechanism is engaged by pivoting at least one exterior wall of the housing to provide tool-less access to the light source. In an alternative embodiment, the main body attaches to a mounting arm and a wall mount housing with a secondary adjustable light source.
Abstract: A sheet-shaped lightguide member has a first surface (11A), which is divided into at least two areas. The sheet-shaped lightguide member has the first surface (11A) and a second surface (11B) that face each other and a peripheral edge surface (11C). The lightguide member receives light through at least a part of the peripheral edge surface, guides the light, and emits the guided light from the first surface (11A) serving as a light exit surface. The lightguide member is divided into the at least two light exit areas (14A, 14B) and has a light-blocking part (18) provided along a boundary between mutually adjacent light exit areas to block transmission of light between the adjacent light exit areas.
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.

Abstract: A backlight module, a base used therein, and a manufacturing method thereof are provided. The backlight module includes a base and a slice-shaped circuit. The base has a back plate including a plate portion and a mezzanine portion. The mezzanine portion is parallelly offset from the plate portion, and the initial position of the mezzanine portion becomes an opening on the plate portion. Because the mezzanine portion is parallelly offset from the plate portion, a containing space is formed between an inner side of the mezzanine portion and the plane of the plate portion. 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.

The screen is in the form of a mesh that has a plurality of tiny holes and covers the inlet section of the housing. Consequently, by use of the screen, the lamp can meet standards for safety, gas flow impedance is reduced to enhance dissipating heat dissipating effect of the heat dissipating unit and insects are prevented from entering the housing.
