Emergency strobe/halogen light

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.

Hood for a unidirectional lamp

A solid state control circuit for storing a preset pattern and discharging a strobe tube in accordance with the preset pattern. A solid state control circuit has a programmable memory comprising a plurality of selective partitioned memory locations, each for storing a separate preset pattern, each said pattern for producing a series of timing pulses for discharging the strobe tube. For example, the patterns many include one, two or three flashes per cycle, depending on operator selection. A transformer in the 'flyback' configuration and current mode control for charging the strobe tube circuitry. The current mode control uses 'lossless' current sensing to limit current flows within the circuitry. The intensity of the strobe tube discharge is varied as a function of the ambient light. An anti-neoning signal disconnects power from the strobe tube after a discharge for a minimum period of time wherein the minimum period is greater than the period of time during which the connection of any electrical power to the strobe tube would result in neoning.
