Abstract

A simulated emergency vehicle display, for providing realistic light and sound in a toy emergency vehicle having a housing, having a front, a back, and a roof. A pair of headlights are located at the front, a pair of tail lights are located at the rear, and a plurality of light bar LEDs are located on the roof. A control circuit alternately illuminates each of the headlights, alternately flashes each of the tail lights three times, and repeatedly illuminates the light bar LEDs in sequence to simulate motion by the light bar LEDs. A speaker is selectively activated to provide a realistic siren sound.

Claims

1. A model emergency vehicle, for providing a miniaturized realistic display simulating a real emergency vehicle, comprising:

a housing, in the shape of an emergency vehicle, having a front, a back, and a top;

a pair of head lights;

a pair of tail lights;

a light bar having a plurality of light bar LEDs;

a control circuit, which when activated alternately illuminates each of the head lights, alternately repetitively flashes each of the tail lights, illuminates each of the plurality of light bar lights in a repeating sequence, wherein the control circuit alternately flashes on one of the tail lights three times, and flashes on the other of the tail lights three times, and wherein the control circuit comprises a decade counter, having ten outputs, and wherein each of the plurality of light bar LEDs is uniquely connected to one of the outputs of the decade counter.

2. The model emergency vehicle as recited in claim 1, wherein two red and two blue colored LEDs are provided as the plurality of light bar LEDs, which are thereby connected to four of the ten outputs of the decade counter.

3. The model emergency vehicle as recited in claim 2, wherein the two blue LEDs are adjacent to each other on the light bar, the two red LEDs are adjacent to each other on the light bar, and wherein the two red LEDs are together adjacent to the two blue LEDs.

4. The model emergency vehicle as recited in claim 3, wherein the light bar LEDs are connected to the decade counter outputs so that for each repeated sequence, one blue, one red, the other blue, and then the other red LED is illuminated to simulate motion with the light bar.

5. The model emergency vehicle as recited in claim 4, wherein the control circuit further comprises a pair of oscillators, each of the oscillators alternately enabled, one of the oscillators driving one of the tail lights, and the other of the oscillators driving the other one of the tail lights, the oscillators clocked and configured so that they each alternately provide three pulses which are used to alternately pulse each of the tail light LEDs three times in a row.

6. The model emergency vehicle as recited in claim 5, further comprising a speaker, a siren speaker switch, and further comprising a phased lock loop connected to the speaker through the siren switch, for generating a siren sound when enabled by the siren speaker switch.
