Abstract: An open mounting frame for use in a recessed lighting fixture is the subject matter. The open mounting frame supports the recessed lighting fixture in a fixture aperture formed in a ceiling. The frame has an annular base ring. The base ring is engagable with the lower surface of the ceiling. The frame includes a pair of spaced apart columnar uprights connected to the base ring. The uprights are diametrically opposed to each other. The columnar uprights are connected to each other by a bridge which is connected to the ends of the columnar uprights. A lock is connected to each of the uprights. The locks engage the upper surface of the ceiling to cooperate with the base ring to hold the frame in the aperture.

Abstract: Disclosed is a lighting fixture apparatus that provides easy lamp, lens, or filter replacement and a method for replacing a lamp, lens, or filter in an adjustable lighting fixture apparatus. The apparatus comprises a frame, a gimble ring, and a lamp. The frame comprises a stop edge and at least one recess and the gimble ring comprises an interior and exterior portion and at least one guide pin extending from the exterior portion. The guide pin fits within the recess of the frame and rotates until it reaches the stop edge to lock the gimble ring in place or to align with the recess for removal.

Abstract: An improved lock used with a recessed lighting fixture is the present subject matter. The fixture is adapted for installation in a mounting aperture in a ceiling. The fixture includes a frame which has a retainer ring for connection to the outside or bottom of the ceiling. A lock is pivotly mounted in the frame and is also movably mounted in the frame. The lock is engageable with the interior or upper surface of the ceiling to hold the frame in the mounting aperture. The lock includes a latch which releasably engages the frame to hold the lock in one position relative to the frame and thereby hold the frame in the mounting aperture. The lock includes a shipping notch engageable with the frame to retain the lock in the frame during shipment of the frame to a site for installation in a ceiling.

Abstract: This invention allows conversion from AC or DC line voltage between 70 and 424 volts to small loads between 2.5V and 18V DC for charging of batteries and operating of small loads. The invention uses a topology including two flyback stages in tandem. This invention has many uses and we are believed to be the first to apply it to battery charging and the operation of small loads. The invention is very cost effective and has feedback both from the input line voltage and output voltage to allow different loads and to allow the universal voltage input. The invention operates at high frequency and thus eliminates large transformers and uses surface mount components. All of this results in its very small size, low heat generation, and high efficiency. The invention draws very little power when connected only to a battery without the AC having been cycled. Primary applications for this invention include low powered uninterrupted power supply (UPS) devices.

Abstract: An adjustable connector is used for positioning a track lighting fixture in a track lighting system. The adjustable connector releasably locks a track lighting fixture housing to an adapter. The adapter is connected to a track of the track lighting system. The adjustable connector includes an arcuate mount fixed to the track lighting fixture housing. A lock is releasably secured to the arcuate mount to secure the arcuate mount to the adapter to determine the selected position of the housing. Release of the lock allows the housing to be moved into another selected position. The lock secures the position of the lighting fixture housing relative to the track at a selected vertical position and a selected horizontal position simultaneously.

Abstract: The power supply converts a high wide ranging AC or DC voltage into a low regulated output voltage. Input rectifiers and filters are provided to rectify and filter the AC and to pass the DC voltage. An integrated switching circuit converts the filtered DC voltage into brief pulses whose duty cycle is varied by a first regulator as an inverse function of the filtered DC voltage.

Abstract: A plate closure for use in an internally illuminated sign having a plurality of wiring ports to provide access to the interior of the sign for connecting wires from a power source including a housing made up of a pair of interlockable halves. Each of the halves has a peripheral sealing lip opposed to the peripheral lip of the other half to form a peripheral housing wall. The housing wall has a pair of substantially parallel opposed end walls, a top housing wall and a bottom wall. A top wiring port is formed in the top wall. A left wiring port is formed in one of the end walls, and a right wiring port is formed in the other of the end walls. Each of the wiring ports provides a selective access to the interior of the housing to provide wiring for a light source. Each of the walls, having one of the wiring ports, has a mounting groove in a portion of the housing wall defining the wiring port. Each mounting groove extends into the respective wall and opens into the respective wiring port.

Abstract: An internally illuminated sign having opposed directional indicating arrow openings including a housing. A light source is mounted in the housing. The housing has a flat stencil with letter openings forming a message. A first directional indicating arrow opening is positioned adjacent to one end of the message and a second directional indicating arrow opening is positioned at the other end of the message. The two arrow openings indicate direction in opposite directions, each away from the message. A first arrow cover is positioned in the first arrow opening and a second arrow cover is positioned in the second arrow opening. A stiff resilient translucent sheet diffuser is mounted on the stencil between the stencil and the light source. The translucent sheet holds the arrow covers in their respective arrow openings.

Abstract: A bar hanger used in a recessed light fixture assembly to support the assembly on a support member. The bar hanger has an elongated arm which has its length substantially greater than its width. A mounting ear is fixed on one end of the arm. The mounting ear is adapted to be connected to a fastener to secure the ear to a support member. The arm has a score extending across the length of the arm so that the arm may be selectively fractured at the score to shorten the length of the arm.
