A lighting assembly includes an LED string affixed to a lamp support connected between first and second lighting sockets and includes an non-conductive coupling and a pair of conductive support segments. Each support segment is connected between the coupling a corresponding lighting socket, either directly or via an intervening endcap. The LED string includes an LED module and a pair of interconnects. The LED module includes one or more LEDs and power circuitry for coupling a supply voltage to the LEDs. The interconnect pair may include positive and negative interconnects. A fixed end of each interconnect is electrically and mechanically connected to a corresponding support segment. The first support segment is electrically coupled to a positive terminal of a voltage source and the second support segment is electrically coupled to a negative terminal of the voltage source, the interconnect pair conveys a supply voltage to each LED module.

LED retrofit assembly with electrically biased support structure

An illumination apparatus includes a monolithic support substrate and light emitting diodes (LEDs) on one or more external sides of the support substrate. The support substrate may comprise an elongated extrusion enclosing a hollow core. The LEDs may be affixed to rigid or flexible electrical substrates. Each electrical substrate may be affixed to an external side of the extrusion and may include embedded LED circuitry. The hollow core may enable the extrusion to be received in a recessed socket of a light fixture, wherein the recessed socket provides structural support for the applicable end of the extrusion, rendering end caps or end socket adapters unnecessary. The light fixture may include a contact protruding from the recessed socket and the electrical substrates may include circuitry configured to couple the LEDs to a source of power not coupled to the protruding contact.

Universal lamp support

An apparatus, manufacture and method of illumination support being a single monolithic substrate with light emitting diodes mounted on the external sides of the monolithic substrate. The necessary circuitry for the LEDs is embedded in one or more rigid or flexible electrical substrate that is affixed to one or more of the external sides of the monolithic substrate. The two terminal ends of the monolithic substrate are designed to fit into the lamp sockets of an existing or new light fixture without the use of end caps or end socket adapters, which provides structural support for the monolithic substrate.

The invention is a display device comprising a solid top transparent, charge conducting material, positioned below the transparent solid material is an active layer comprising an electrochromic material and an electrolyte, and positioned below the active layer is a working electrode and a counter-electrode arranged to be isolated from one another, wherein the distance between the working and the counter electrode is greater than two times the thickness of the active layer between the electrode and the conductive material.

Electrochromic display device

The present invention relates to a composition and to a display device having the composition positioned between electrodes. The composition contains: (a) a compound that undergoes a reversible redox reaction to generate a pH gradient between the two electrodes, (b) an indicator dye, (c) a charge transport material, and optionally, (d) a matrix material and (e) an opacifier, and (f) secondary redox couple wherein components (a), (b), and (c) are different from one another and the standard reduction potential of component (a) is less than the standard reduction potential for the other components. Depending on the electric field present between the electrodes, a display image may be generated.
