Abstract: A full function light bar is provided mountable inside a vehicle against the windshield. The light bar is an assembly of several light sources, including strobe lamps, flashing lamps, oscillating lamps, and an aimable take down lamp. The light bar is not limited in application to one specific vehicular model and is adaptable and adjustable to conform to the windshield, rear window, or other interior cab surfaces of varying shape (curvature). The light sources are supported on a flexible support mount which has adjustable, flexible gaskets. End caps and the gaskets screen the inside of the vehicle from the light emitted by the light bar. The support mount is hung on adjustable brackets which allow the light bar to be raised, lowered and tilted to further facilitate conformance with the windshield.

Abstract: A light bar contains one or more rows of light-emitting diodes (LED's) in a housing which extends across substantially the entire width of a windshield of a vehicle and is narrow in width to minimize interference with visibility through the windshield. The LED's are arranged in banks generally symmetrically arrayed about the center of the length of the housing. Two of the banks, preferably equidistant from the center, are tilted in opposite directions to each other so as to project light toward the right side and left side of the vehicle. A mechanism is provided for displacing and tilting the housing and may use pivotal arms attached to the end of the housing or adjustable Z-shaped hangers attached preferably to clamps such as visor clips already on the vehicle.

Abstract: A warning lamp, provides multi status indication by being illuminated in selected ones of a plurality of colors or by flashing a selected color or colors sequentially. The lamp has a pair of printed circuit boards disposed, one in a base and another upstanding from the base along a central axis, extending midway through the upstanding board. Around the upstanding board and coaxial therewith is a lens which is mounted in assembled relationship with the boards and the base. The upstanding board has arrays of light emitting diodes (LEDs), disposed along spaced lines which are parallel to the axis. The LEDs along different lines provide light of different color, for example, red, green and amber. The printed circuit boards provide a subassembly in which the bottom portion of the upstanding board and the other board are contained in a plastic casting disposed in a recess in the base.

Abstract: In order to diagnose a strobe lamp system in a manner to isolate failure (burn out) of the strobe lamp from failures in its operating circuits, particularly the DC-DC converter which provides operating voltage to the lamp, a microcontroller, which produces sequences of signals corresponding to sequences of flashes from the lamp, is programmed so that the sequences of signals are not produced in the absence of output voltage from the DC-DC converter. The microcontroller is connected via a circuit including an LED to the circuit which converts the signals into trigger pulses for the strobe lamp. The failure of the strobe lamp to flash while the LED flashes isolates failures to the DC-DC converter, whereas flashing of the LED alone isolates failure to the lamp.

Abstract: A visual signaling device has one or more light source modules arranged in a stack. Each module is of "Tri-liptic" i.e. generally triangular shape, but with the triangle corners rounded. Inside the triangle, is a perfect circle, to aid in the optical dispersion of the light source. The modules are each formed by back and front moldings. The front molding defines one of the sides of the module, while the back molding defines the other two sides of the module. The light source module contains a light source (incandescent, halogen, rotating, strobe or LED) on a printed circuit board. This module also contains the electronics, which operate the light source, and can cause it to flash, be illuminated constantly or operate a rotating reflector around a stationery bulb. A conduit, which is a strip of printed circuit board with connectors at its opposite ends, extends between the top and bottom of each module of the stack.

Abstract: A resilient mount for rotating warning light systems includes a mounting base having a plurality of mounting feet, each of which includes a special grommet mounted within an aperture formed therein. The grommets are selectively shaped so as to absorb and dissipate substantially all shock loads which would ordinarily be delivered to the rotating warning light system, and particularly, to the fragile bulb itself. The resiliently mount further prevents noise from being transmitted from the rotating light back into the vehicle to which the mounting base is connected.
