The present disclosure provides a lighting device for use with inflatable products, such as balloons. Specifically, the lighting device may be configured to utilize external audio to produce a pattern of light corresponding with the external audio. The lighting device is able to couple to a balloon to light up the interior of the balloon without the significant loss of gas or other inflating fluid from the balloon.

Provided in this disclosure is an apparatus for marking an implement, such as a snow plow. An elongated tubular member retains an illuminated member such an LED element within the interior. Conductor wiring connects a source of electrical energy to the LED. An enclosing cap includes a crimped end portion secured to the bottom end of the elongated tubular member. A cylindrical end portion has a hollow interior for admitting the conductor wiring for connection to the source of electrical energy. A perpendicular mounting bracket has a horizontal mounting surface and a vertical mounting surface, formed together at a right angle. The horizontal mounting surface is configured for connecting to the cylindrical end portion of the enclosing cap so that the elongated tubular member is disposed in a substantially vertical position. The vertical mounting surface is configured for connecting to a vertical portion of the snow plow.

An illumination apparatus comprises a plurality of LEDs aligned to an array of directional optical elements wherein the LEDs are substantially at the input aperture of respective optical elements. An electrode array is formed on the array of optical elements to provide at least a first electrical connection to the array of LED elements. Advantageously such an arrangement provides low cost and high efficiency from the directional LED array.

An integrated ceiling device includes integrated ceiling device including an electronic device housing, a heat dissipating structure, a light source, and a reflection/refraction assembly. An air gap is defined between the electronics housing and other components allowing ambient air to flow therethrough for cooling.

An LED string light includes a first conducting wire, a second conducting wire, and a third conducting wire which are arranged in parallel. The first, second, and third conducting wires all comprise a conducting wire core and an insulation layer coating a surface of the conducting wire core, and the first conducting wire and the second conducting wire define a plurality of lamp welding regions. The LED string light also includes a plurality of SMD LEDs respectively disposed at the plurality of lamp welding regions. The first conducting wire is selectively cut off at a plurality of first positions and the second conducting wire is selectively cut off at a plurality of second positions based on whether the plurality of the SMD LEDs are connected in series or in hybrid of series and parallel.

A lighting system with vacuum intake is provided, having a lighting structure including at least one light-emitting element dimensioned to illuminate a region, and a lighting support structure extending at a first end thereof from the lighting structure and enabling repositioning of the lighting structure relative to a second end of the lighting support structure. The lighting support structure hays an air conduit extending therealong and connectable or connected towards the second end of the lighting support structure to a vacuum system, the air conduit being in fluid communication with a vacuum intake positioned towards the lighting structure.

In a first aspect of the subject invention, a solid state HID canopy light fixture retrofit assembly is provided which includes: an inner panel; and, a plurality of edge members perimetrically bounding the inner panel. Each of the edge members includes: a first edge panel secured to the inner panel; a downwardly angled second edge panel depending from the first panel; and, a flange extending from the second edge panel. The first and second edge panels are each sized sufficiently to support thereon at least one board containing a plurality of solid state light generating elements. The inner panel and the edge members collectively define a contained volume sized to accommodate at least one driver for electrically powering the solid state light generating elements. The subject invention provides an assembly which is readily useable to retrofit HID canopy light fixtures from ballasted HID lighting to non-ballasted solid state lighting.

A winding mechanism includes a housing, an inner cylinder and a wire. The housing is formed with an accommodating space therein. An inner surface of the housing is formed with an internal thread structure. The inner cylinder is disposed in the accommodating space and defines a central axis. An outer surface of the inner cylinder is formed with an external thread structure. The external thread structure is cooperated with the internal thread structure. The inner cylinder is capable of displacing along the central axis by rotating relative to the housing. The external thread structure includes at least two contact portions and at least two non-contact portions, and gaps are formed between the non-contact portions of the external thread structure and the internal thread structure. An end of the wire is connected to the inner cylinder and is wound along the external thread structure of the inner cylinder.

A method for providing a removable quick-connect between a junction box and an electrical fixture is provided. A first junction box mounting plate is removably affixed to the junction box, and a first electrical connector is positioned in a channel in a front face of the first junction box mounting plate. A second electrical fixture mounting plate is removably affixed to the electrical fixture, and a second electrical connector is positioned in a slot in a projection extending upwardly from a front face of the second fixture mounting plate. The channel in the front face of the first junction box mounting plate is aligned with the projection extending from the front face of the second electrical fixture mounting plate. The channel includes angled side walls and the projection includes side walls angled in the opposite direction. The projection is then slid into the channel until the first electrical connector engages the second electrical connector.
