This invention provides a process and device for simultaneous laser welding; after using the moving lower die and the fixing upper die to make the base and the lens attached, by using the light pipe, for example, transparent substances or other cheap materials, to make the laser, which is emitted from the laser source, emit through the lens to a welding region of the base after being processed, to operate rapid and average heating to the welding region; meanwhile, using the welding cylinder to press the base and the lens together, to make base and the lens pressed and welded together in molten state, and when welding, it does not generate powder or other defects, and, at the same time, it can make the height H and the width w of the generated waste selvage between [0, 0.4] mm, which can improve the performance of welding object more efficiently.

A lighting apparatus includes a front enclosure and a back enclosure including guide slots formed thereon. A mounting plate including a plurality of LEDs mounted thereon is attached to the back enclosure. A circuit board is attached to the mounting plate. A center extrusion is attached to the back enclosure. A plurality of spaced fin extrusions are attached to the mounting plate and positioned in the guide slots of the back enclosure. Side rails are attached to the mounting plate and back enclosure and spaced from the fin extrusions. The plurality of spaced fin extrusions and side rails allow passage of air in an upward direction between the spaced extrusions and side rails transferring heat generated from the lighting apparatus to the air.

A lighting fixture includes a first housing portion and a second housing portion. The first housing portion includes a base and a wall extending outwardly from substantially the perimeter of the base. A top portion of the wall includes one or more hinges extending outwardly therefrom. The second housing portion includes a front panel and a side panel extending outwardly from substantially the perimeter of the front panel. A top portion of the front panel includes at least one slot. The second housing is coupled to the first housing in an open position when the hinge is inserted into the slot and the front panel is disposed elevationally above the base. The second housing is coupled to the first housing in an operational position when the hinge is inserted into the slot and the front panel covers the base.

A lamp device includes a lamp seat, a lampshade having an inner inclined surface and defining an opening, and a securing unit having a cover shell and a plurality of locking mechanisms. The cover shell is disposed in the opening and connected to a mounting plate of the lamp seat. Each locking mechanism has a locking member having a ring portion that is disposed rotatably in a respective one of receiving notches of the cover shell, and an arm portion that is co-rotatable with the ring portion between an unlocked position, and a locked position where the arm portion is disposed outside of the respective one of the receiving notches and abuts against the inner inclined surface, such that the lampshade is fastened to the lamp seat.

An LED tube lamp includes a lamp tube, two end caps, an LED light strip, a power supply, and a reflective film. At least a portion of an inner surface of the lamp tube is formed with a rough surface, and the roughness of the rough surface is higher than that of the outer surface. Each of the two end caps is coupled to a respective end of the lamp tube by a gel. The LED light strip is disposed on an inner surface of the lamp tube with a plurality of LED light sources mounted on the LED light strip. The power supply is disposed at one or two of the end caps. The power supply is electrically connected to the plurality of LED light sources. The reflective film is disposed on the inner surface of the lamp tube.

A flexible light engine, comprising insulating lower and upper laminate sheets; first and second electrically conductive metallic bus bars between the sheets; a plurality of electrically conductive metallic conductors between the sheets being disposed laterally between the bus bars, wherein each conductor defines two metallic contacts exposed in register with adjacent perforations in the perforated upper sheet; wherein each of the bus bars further comprises respective at least two interconnectors, and wherein the conductors are connected to respective interconnectors to define at least two series circuits and connectable in parallel between the bus bars, wherein each of the series circuits comprises a subset of the plurality of metallic conductors; and a plurality of LEDs attached to the contacts defining at least two series LED strings and connected in parallel between the bus bars, each said LED string comprising a plurality of LEDs.

A mounting assembly includes a mounting plate that has a central aperture and a plurality of elongated slots disposed on opposite sides of the central aperture. The plurality of elongated slots are configured to flexibly mount a light fixture to junction boxes or recessed cans of different sizes. Further, the mounting assembly includes one or more torsion spring brackets to mount the light fixture in recessed cans. The one or more torsion spring brackets are configured to toollessly couple with the mounting plate via one or more of the plurality of elongated slots. Once the light fixture is mounted to a junction box or a recessed can, the mounting plate allows the light fixture to rotate clockwise or counterclockwise along one or more of the plurality of elongated slots. Furthermore, the mounting assembly includes spring clip brackets and mousetrap like spring clips to surface mount the light fixture.

A adapter security system adapted to be attached to a cable is taught. The adapter security system includes a wire, at least one adapter that is carried by the wire, and a clamping assembly that is adapted to attach the wire to the cable. The adapter security system provides a means of securing adapters at the location of a presentation while also providing convenient access for the user to the adapters.

An environmentally responsible, optically efficient, low glare lighting device comprises: a tubular body (1); a first plurality of solid state light emitting elements (2) arranged on a first surface of a first carrier (3) inside said tubular body; and a flexible reflective sheet (4) covering said first surface and a first part of an inner surface of the tubular body (1) to an extent (6) sufficient to obscure direct visibility of the light emitting surface of the first light emitting elements (2) if viewed through a light outlet portion (5) from a location external to the tubular body (1), wherein said light outlet portion includes a second part of the inner surface that is not covered by the flexible reflective sheet. A convenient method for manufacturing the device is also described.
