Abstract: Light bars, and lighting systems and vehicles that include light bars. The light bars include a plurality of light emitting modules coupled together at flexible joints to allow a single light bar to be affixed to surfaces of varying curvatures, such as an interior window surface of a vehicle. The size of the light bar is easily customizable due to its modular nature. In some examples, a controller or other electronic element is adapted to detect a number and/or configuration of modules in a given light bar.

Abstract: An example warning device can include: a plurality of light sources forming an array; a plurality of reflectors, with at least one reflector being associated with each of the plurality of lights; at least one lens for each of the plurality of lights; and an optical prism plate that directs light from one or more of the plurality of lights to one of a plurality of far field light spots.

Abstract: Lighting systems, devices, and units that provide illumination according to a detected orientation relative to a reference plane or a reference vector. In some examples, a light bar for use on a vehicle includes first and second sets of light emitters that are selectively activated and inactive based on a detected orientation of the light bar relative to a reference plane or reference vector.

Abstract: A signaling system for mounting to an exterior surface of an emergency vehicle is provided. The signaling system includes a light bar and a pair of mounting feet. The light bar can include a plurality of signaling devices supported on and distributed along a base member and enclosed by a cover. The light bar can be secured to the mounting feet via a plurality of fasteners. The mounting feet can be connected to the emergency vehicle via roof straps. Each mounting foot can include a base, which can have a support portion, a contoured portion, and a pair of compartments; a pair of seals associated with each compartment; a pair of covers, which can be translucent, removably mounted to the base to enclose the compartments; and a roof strap secured to the base. Each compartment can house a signaling device, such as a lamp assembly.

Abstract: The present disclosure provides a lighting device that includes an array of LEDs arranged on a circuit board with a reflector that rotates relative to the LEDs to reflect the light in various directions. The reflector according to the present disclosure includes a compact construction that allows for effective light reflection. A related lighting system and method is also provided.

Abstract: A light assembly is disclosed which can include an LED array and a reflector. The LED array can include a plurality of LEDs which are disposed such that each LED is substantially aligned to define a focal axis. Each LED can emit light substantially along an optical output axis, with each optical output axis being perpendicular to the focal axis. The optical output axis of the LED array can be disposed in intersecting relationship with the reflector surface. The reflector can be defined by a curve section defined with respect to a principal axis. The principal axis and the output axis of the LED array can be in non-parallel relationship with each other. The optical output axis of the LED array can be substantially perpendicular to the principal axis of the curve section of the reflector.
