The abutting surface is engaging with the track abutting surface.

The current invention applying super slim LED-unit(s) has built-in contactors has (a) magnetic only or (b) conductive magnetic-movable-kits so can attach or detachable metal magnetic-field reactive buss-strips. The conductive-movable type which also can deliver electric current from buss-strips of track light. The super slim LED light or units is a DC powered LED light has optics design become super thin and none bright-spots. The said LED-units install under the light-block material housing or parts, and light-beam go through at least of reflective surface at inner surface or walls. The said LED-unit install on hard or bendable circuit board with divider the compartment only has LED, lit-lens, reflective housing. The compartment is only space where light-beam traveling and has multiple times reflected and emit out from top lens. The said light beam emit out from LED-unit(s) reflected by high reflective surface or wall including (1) white high-polished plastic or (2) metalized mirror-like or (3) shining metal piece back-and-forth and light emit out from top lens. The current invention has multiple time reflective and refractive optic theory to make the super thin light for SMD LED(s) on hard or bendable PCB to get in-direct light beam. To get none bright-sports by not install LED(s) under face top lens. The Track LED light or LED-unit has slim features with different size can use as ceiling, closet, kitchen, laundry, door, garage, patio or anywhere for building, residence, house for indoor or outdoor use.

A light strip system for securing luminaire units and supplying them with power having an elongate support structure, especially at least one support rail for securing the luminaire units and power supply extending along the support structure for supplying the luminaire units with power. The power supply includes first lines which extend along the support structure and define a first power supply circuit (I), and second lines which extend over part of the length of the first power supply circuit (I) along the support structure and define a second power supply circuit (II) which is designed to be in electrical contact with the luminaire units, the first power supply circuit (I) being coupled to the second power supply circuit (II) by a converter unit which converts a first supply voltage available in the first power supply circuit (I) to a second supply voltage suitable for operating the luminaire units.

A mounting assembly for mechanical and electrical engagement of a power module includes a stem having a base operably coupled to the power module and a distal end distal the base, a first electrode arm extending perpendicularly from a first side of the and having formed thereon a first electrode disposed on the first electrode arm to form a first incline surface, and a first locking arm extending perpendicularly from the first side of the and having formed thereon a first locking surface. A plane of the first incline surface intersects a plane of the first locking surface.

A lighting assembly connector is configured for being inserted into a lighting track. The lighting assembly connector includes a casing having a width defining a lateral direction and a length defining longitudinal direction. The length is greater than or equal to the width. The casing is definable as including three sections each defining one-third of the length. The three sections include a middle section, a first end section including a first longitudinal end of the casing and a second end section including a second longitudinal end of the casing. The middle section has a greater average width than each of the first end section and the second end section. The lighting assembly connector also includes a plurality of electrical contacts extending out of the casing each configured for contacting a respective line of the lighting track; and at least one fastener connected to the casing configured for removably connecting the lighting assembly connector to the lighting track.

An electrical coupling device, such as a surge protector for a rail or other conductive structure, includes a pair of terminals, and a jumper for selectively electrically coupling and decoupling the terminals. Movement of the jumper may expose part of the jumper or one or both of the terminals, such as for use as a test point. A surge module with one or more surge protection features may fit into a base that includes the terminal and the jumper. The module may have an interface feature, such as a protruding post, that prevents engagement with the base if the base is not properly engaged with the rail or other structure. In one embodiment, a threaded rod may serve as the jumper and in one position electrically couples the terminals and in another position electrically decouples the terminals and one end of the threaded rod becomes exposed for use as a test point.

This disclosure provides connectors for smart windows. A smart window may incorporate an optically switchable pane. In one aspect, a window unit includes an insulated glass unit including an optically switchable pane. A wire assembly may be attached to the edge of the insulated glass unit and may include wires in electrical communication with electrodes of the optically switchable pane. A floating connector may be attached to a distal end of the wire assembly. The floating connector may include a flange and a nose, with two holes in the flange for affixing the floating connector to a first frame. The nose may include a terminal face that present two exposed contacts of opposite polarity. Pre-wired spacers improve fabrication efficiency and seal integrity of insulated glass units.
