The first signal piece is arranged in the first accommodation chamber, and the cover plate defines therein a mounting hole in communication with the first accommodation chamber. The second signal piece is arranged on the second casing, and the second casing is arranged in the mounting hole and is in detachable connection with the cover plate. The first signal piece contacts with the second signal piece.

Abstract: A high bay light fixture with a monolithic die cast housing. An LED driver and a sensor socket can be installed in a component tray in the center section. The left section and the right section of the housing have LED channels in which LED assemblies are mounted. Lenses can be slid into the LED channels via the open ends of the LED channels. Channel caps are attached to the open ends. Closed ends can also be formed into the housing. The channel caps and the closed ends prevent the lenses from sliding out of the LED channel. Lens tabs prevent the lens from falling out of the LED channels. The housings have bonding bracket mount points and can be attached end to end by bonding brackets attached to the bonding bracket mount points, thereby forming dual and triple fixtures.

Abstract: An electronic door chime can meet safety standards and be compatible with doorbells. A new electronic door chime can safely powered doorbells and can be configured in a single gang box, while also being compatible with simple push button doorbell devices. A new electronic door chime can safely provide continuous power to smart doorbells, also called IOT doorbells, to drive the cameras, audio interface and other components within the smart doorbell. The new door chime complies with safety standards and can be configured in a single gang box. The disclosed systems include a separation board, to comply with UL voltage separation requirements, and the disclosed embodiments can fit into standard single gang box flush to a wall.

Abstract: A flush mount lighting fixture can incorporate aspects that provide reconfigurability and convenience. Selector switches can provide a wide selection of illumination levels and color temperatures. The switches may be inaccessible while the fixture is installed to thereby prevent unwanted adjustment. A magnetically attached faceplate is easy to install, replace, adjust, and change for other faceplates. A top diffuser may be interchangeable with a wall wash insert. The top diffuser can produce a lighting pattern that is circularly symmetric with a fixture axis of the fixture. The wall wash insert produces a lighting pattern that is asymmetrical and may be offset from the fixture axis of the fixture.

Abstract: A luminaire can include a light engine producing a light beam, a zoomable optic changing the light beam's solid angle, and a light conditioner that may diffuse the light beam, split the light beam, or produce a wall wash beam from the light beam. The luminaire may removably attach to a frame mounted in a ceiling. A power supply powering the light engine and a collar may also removably attach to the frame. The luminaire is located in a collar hole in the frame to thereby pass through the ceiling. The collar adapts the collar hole for differently sized luminaires such as 4 inch or 6 inch luminaires.

Abstract: An epoxy resin composition, a transparent composite material including the same, and a laminated board. The epoxy resin composition includes an epoxy resin A and an epoxy resin B. The refractive index of the epoxy resin A is 1.54-1.8 and the light transmittance of the epoxy resin A is 90%. The refractive index of the epoxy resin B is 1.54-1.8 and the light transmittance of the epoxy resin B is greater than 90%. The epoxy resin A is an organosilicon modified epoxy resin. The epoxy resin B is another type of epoxy resin. The organosilicon modified epoxy resin satisfying a specific condition and another type of epoxy resin also satisfying the specific condition are combined to form a specific epoxy resin composition. The composite material prepared from the epoxy resin composition, a curing agent, and a curing accelerator has the advantages of having high light transmittance and high bending strength, and also has high bonding strength.

Abstract: A luminaire a small number of carefully designed extrusions is easily manufactured. The housing is formed by joining four pieces having a first extrusion profile. A second extrusion profile is used for the side and end covers. A third profile is used for access covers. The housing frames a lens, such as an acrylic sheet, and long lines of LEDs are positioned to shine directly into the side of the lens. A reflective layer on the lens directs all or some of the LED light out the luminaire's front, perhaps directing some light out the back. Strategically positioned diffusors ensure a pleasing lighting effect. The result is a very thin and light weight luminaire having a large surface area. The luminaire can be suspended by threaded nipples, by cables threaded through holes in the back, or by brackets screwed to threaded inserts.

Abstract: Luminaire housings for architectural, industrial and warehouse applications have extrusions with parallel flat sides connected by a cross member. The wireway can be enclosed by the extrusion's roof or by cover segments clamped over an open top extrusion. Wireway openings provide access to the wireway. Nuts slid into T-channels in the roof or cover segments provide for mounting or suspension via wall brackets, cables, and housing brackets. Threaded nipples accessible through the roof or cover segments provide for pendant stem mounting. Continuous run brackets can join housings end to end. Optical elements slid into slots and channels in the housing can be retained by end caps. A housing cover over the wireway can be clamped in place by screws threaded into fixture brackets retained within the housing. The housing grooves in the cover segments can slidably engage the extrusion until the cover segments are clamped in place.

Abstract: A luminaire for architectural, industrial and warehouse applications can be assembled using an extruded housing having curved sides connected by a cross member. Window openings in the curved sides can allow light to exit toward the sides of the luminaire while most of the light exits through a lens on the bottom. The extrusion can have channels and slots such that optical elements and an LED array can be slid into the housing and retained by endcaps. A housing cover can overlie a wireway while being held in place by screws creating a clamping force between the housing cover and fixture brackets retained within the housing. The luminaire can be suspended by the fixture brackets or by elements attached to the fixture brackets.
