摘要： A light bar for mounting on an emergency vehicle to provide warning light signals. An elongate body portion has an elongate axis, the elongate body portion adapted to be mounted on the emergency vehicle so that the elongate axis traverses an axis coaxial with the direction of the travel of the emergency vehicle. At least three vertically spaced lighting layers are provided, each layer having at least one emergency light source, the emergency light sources on each layer cooperating to provide a transient high intensity warning light signal 360.degree. around the light bar. At least four linear rows of emergency light sources as viewed from the top of the light bar are also provided, the rows being substantially parallel to the elongate axis, each row having at least two emergency light sources, at least one row located in each of the layers and at least one layer having at least two rows, the emergency light sources in each row cooperate to provide a transient high intensity warning signal 360.degree. around the light bar. Each end of the body has projecting extensions which have a recess for accommodating mounting hardware. A spot light or other device may be nested in the bar. The fixtures may be stacked and may be positioned off center when the vehicle is in a fend off position. The fixtures may also be aimed to cross over each other or operate in response to vehicle speed.

摘要： A hood for mounting a unidirectional lamp adjacent a window, such as a windshield, of an emergency vehicle and within a passenger compartment of the vehicle for directing light through the window. The lamp includes a housing having a forward portion defining an opening therein, a light source within the housing, and a lamp lens adjacent the forward portion of the housing and covering at least a portion of the opening for directing light from the light source through the opening. The hood comprising a hood body mountable adjacent the window having a rearward end defining a first open port dimensioned for receiving the forward portion of the housing, a forward end defining a second port opposite the first port, and a light pathway between the first and second ports for transmission of a beam of light from the light source through the body. A hood lens is within the body for optically altering the beam of light transmitted along the light pathway. The hood lens is moveable between an aligned position within the light pathway in which the beam of light being transmitted along the light pathway is transmitted therethrough and is optically altered thereby, and a nonaligned position in which the beam of light being transmitted along the light pathway is not transmitted through the hood lens.

摘要： A signal light comprising a base, a frame pivotally mounted on the base for pivoting about a first axis, and a bracket pivotally mounted in the frame for pivoting about a second axis, generally perpendicular to the first axis. A light source is mounted on the bracket so that it pivots with the frame and bracket about the first and second axes. The signal light includes apparatus for pivoting the light source about the first and second axes. This apparatus comprises a disc, having grooves forming first and second cam surfaces. The grooves are preferably located in opposite faces of the disc. A first cam follower follows the first cam surfaces and causes the frame to pivot. A second cam follower follows the second cam surface and causes the bracket to pivot.

摘要： 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.
