A lighting appliance includes a housing, a lighting element disposed in the housing is capable of displaying multiple color temperatures, a control unit disposed in the housing, an electrical communication system in communication with the lighting element and the control unit, and a sensor disposed on a portion of the housing, where the sensor is in communication with the lighting element and the control unit via the electrical communication system, and when a motion signal is detected by the sensor, the control unit is configured to instruct the lighting element to illuminate in a predetermined light mode for a predetermined time.

Deterrent device attachments are provided each having a light emitting thermal source positioned by a support board to emit light from within a housing of the deterrent device, with the support board bent to provide surface areas to dissipate heat generated by the light emitter.

A vehicle barrier gate arm has an anti-roll end cap which prevents the gate arm from rolling when it has become detached from its gate operator. The end cap comprises a distal outer panel and three or more protrusions positioned radially equidistant along the periphery of the distal outer panel. The protrusions extend outward from the distal outer panel perpendicular to the gate arm. The protrusions may form a square, triangle, trapezoid, or cross and may taper inward in a proximal direction or may meet the outer cuff at a sharp angle. Furthermore, an outer and inner cuff form a friction fit with the end of a gate arm to removeable attach the end cap to the distal end of the gate arm.

The invention relates to an embodiment in which the textile component comprises at least one flexible thread that can be woven. A plurality of semiconductor columns are attached in or on the thread and are configured to generate radiation. Furthermore, a plurality of electrical lines are located in or on the thread, by means of which lines the semiconductor columns are electrically contacted. An average height (H) of the semiconductor columns in a direction transverse to a longitudinal direction (L) of the thread is at most 20% of an average diameter (D) of the thread.

A portable illumination device, including a main body, an illumination unit movably disposed on at least a portion of the main body to emit a beam of light and illuminate a surrounding area, at least one sensor disposed on at least a portion of the main body to turn on the illumination unit in response to detecting an external condition, and a surface fastener disposed on at least a portion of the main body to removably connect the main body to an external surface.

Systems and devices for temporarily disabling an assailant or other target using disabling flashes of light from a light-emitting device. A tactical lighting system also includes protective eyewear that is paired with the light-emitting device and configured to shutter in synchronization with the pattern of disabling light flashes to protect the wearer’s eyes while disabling an assailant or other target. In one embodiment, the tactical lighting system is modular, with each module being functional independently of the other modules.

A safety lighting assembly enabled to cast light rearward toward the surface to which it is attached. The safety light assembly provides additional portions for emitting light in selected directions so as to facilitate situation awareness of the object.

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.

A lighting assembly is configured to create an emergency notification. The lighting assembly has a housing with a housing first surface and a housing second surface. A plurality of strobe lights and/or light emitting diodes (LEDs) is arranged into at least one row and at least four columns. A direct current power system is joined to the plurality of lights and further comprising a printed circuit board electrically coupled to radio frequency relay switch, and a battery. A wireless remote is communicatively coupled to the radio frequency relay switch. Activating the wireless remote directs the printed circuit board to provide power to the plurality of lights creating the emergency notification.
