Abstract: A light bar may include a light head with chip-on-board (COB) light emitting diode (LED) and an optic component mounted adjacent to the COB LED. The light bar may comprise short and long center modules. The light bar may include a plurality of housing modules where each housing module includes a light head and a lens cover having a top portion that is substantially impervious to ultraviolet radiation, and a lens portion extending downward from the top portion in generally opposing relationship with the light head. The light bar may include a circuit board including a wire-to-board connector, and a light head including a wire-to-board connector mated with the wire-to-board connector on the circuit board to electrically connect the light head to the circuit board. The light head may include a holographic diffuser.

Abstract: A mounting foot for mounting a light bar on a roof of a vehicle includes at least one platform. The platform includes a recess for slidably receiving a base of a light assembly to mount the light assembly on the platform. The light assembly has a base fixedly secured to the platform and a light enclosure rotatably connected to the base of the light assembly.

Abstract: A modular light bar having crisscross lighting in the front and rear. Each module may include two horizontal layers of lighting supported on the underside of a mounting plate and connected to a terminal strip. A quick disconnect connects the terminal strip to a dimmer/flasher and controller.

Abstract: A light source with an integral surface of revolution to project an emergency warning light signal for a vehicle in a substantially horizontal 360° arc. A centrally positioned mirror assembly has a plurality of light sources spaced about the mirror assembly.

Abstract: The device includes a visible light source and a transmissive/reflective layer on a vehicle. The layer is between the source and an observer and transmits emergency warning signals of various colors to the observer. In addition, the layer reflects ambient light so that when the light source is not illuminated the appearance of the device is changed and the emergency warning colors, if any, of the device are masked.

Abstract: A visible light source adapted to be mounted on the vehicle for generating visible light to be used to create warning signals which are viewed by observers remote from the vehicle. A dichroic element adapted to be mounted on the vehicle and adjacent to the visible light source transmits at least some of the visible light generated by the light source and reflects at least some of the visible light generated by the light source. The transmitted and reflected light provides warning light signals within different wavelength ranges when viewed by an observer remote from the vehicle.

Abstract: An emergency warning light for a vehicle including an LED light engine in contact with a heat sink and covered by a lens including a plurality of total internal reflection (TIR) surface configurations corresponding to the LEDs. A constant current step up power supply circuit energizes the LEDs.

Abstract: A light bar comprises a plurality of modules and a control circuit including a power supply for selectively energizing each of the modules. Each module includes a strobe lamp having an anode and a cathode for energizing the strobe lamp and having a trigger for firing the strobe lamp, a reflector positioned adjacent the strobe lamp to reflect light emitted by the strobe lamp and a circuit including a capacitor connected to the anode and the cathode for energizing the strobe lamp. The circuit of the module connects the capacitor and the trigger to the control circuit. An incandescent lamp or a high intensity discharge lamp may be used separately or in combination with the strobe. Multicolor operation or the use of LCD panels as filters or reflectors is also contemplated.
