Automotive warning and brake light arrangement

Claim 2

A combination warning and brake light arrangement for an automotive vehicle, comprising: a first lamp adapted to be mounted substantially centrally of a leading vehicle rear end in the vicinity of a rear window, for emitting red light of sufficient intensity to alert a driver of a following vehicle of the application of the leading vehicle's brakes; a second lamp adapted to be mounted in close proximity to said first lamp, for emitting amber/yellow light to warn the driver of the following vehicle of the presence of the leading vehicle and to focus the attention of said driver in the region of said rear window at which said first lamp is located; and switching means arranged with an ignition system and a braking system of the leading vehicle and coupled to said first and said second lamps, for energizing said first lamp only when the brakes of the leading vehicle are activated and for energizing said second lamp continuously when said brakes are not activated and said ignition system is in an ON state.

Claim 3

The warning and brake light arrangement of claim 1, including photosensor means associated with said second lamp for controlling the intensity of the emitted amber/yellow light in corresponding relation to a level of ambient light so that the intensity of said amber/yellow light is just sufficient for comfortable observation by the driver of the following vehicle at various levels of said ambient light.

Claim 4

The warning and brake light arrangement of claim 1, wherein each of said first and said second lamps comprises an array of light-emitting diodes (LEDs).

Claim 5

The warning and brake light arrangement of claim 1, wherein each of said first and second lamps comprise incandescent bulbs.

Claim 6

The warning and brake light arrangement of claim 1, wherein said first lamp comprises a series of red light emitting diodes (LEDs) and the second lamp comprises a series of amber/yellow incandescent bulbs.

Claim 7

The warning and brake light arrangement of claim 3, wherein the turn on response time of said first lamp is at most about 60 nanoseconds.

Claim 8

The warning and brake light arrangement of claim 4, wherein the turn off response time of said second lamp is at most about 40 nanoseconds.

Claim 9

A combination warning and brake light arrangement for an automotive vehicle, comprising: a lamp housing adapted to be mounted substantially centrally of a leading vehicle rear end in the vicinity of a rear window; first light emitting means mounted in said housing for emitting red light of sufficient intensity to alert a driver of a following vehicle of the application of the leading vehicle's brakes; second light emitting means mounted in said housing for emitting amber/yellow light to warn the driver of the following vehicle of the presence of the leading vehicle and to improve the awareness of said driver in the region of said rear window at which said lamp housing is located; and switching means associated with an ignition system and a braking system of the leading vehicle and coupled to said first and said second light emitting means, for energizing said first light emitting means only when the brakes of the leading vehicle are activated and for energizing said second light emitting means continuously when said brakes are not activated and said ignition system is in an ON state.

Claim 10

A combination warning and brake light arrangement for an automotive vehicle, comprising: a lamp housing adapted to be mounted substantially centrally of a leading vehicle rear end in the vicinity of a rear window; first light emitting means mounted in said housing for emitting red light of sufficient intensity to alert a driver of a following vehicle of the application of the leading vehicle's brakes; second light emitting means mounted in said housing for emitting amber/yellow light to warn the driver of the following vehicle of the presence of the leading vehicle and to improve the awareness of said driver in the region of said rear window at which said lamp housing is located; and switching means associated with an ignition system and a braking system of the leading vehicle and coupled to said first and said second light emitting means, for energizing said first light emitting means only when the brakes of the leading vehicle are activated and for energizing said second light emitting means continuously when said brakes are not activated and said ignition system is in an ON state.

Claim 11

The warning and brake light arrangement of claim 8, including photosensor means associated with said second light emitting means for controlling the intensity of the emitted amber/yellow light in corresponding relation to a level of ambient light so that the intensity of said amber/yellow light is just sufficient for comfortable observation by the driver of the following vehicle at various levels of said ambient light.

Claim 12

The warning and brake light arrangement of claim 8, wherein each of said first and said second light emitting means comprises an array of light-emitting diodes (LEDs).

Claim 13

The warning and brake light arrangement of claim 8, wherein each of said first and second light emitting means comprise incandescent bulbs.

Claim 14

The warning and brake light arrangement of claim 8, wherein said first lamp comprises a series of red light emitting diodes (LEDs) and the second lamp comprises a series of amber/yellow incandescent bulbs.

Claim 15

The warning and brake light arrangement of claim 10, wherein the turn-on response time of said first light emitting means is at most about 60 nanoseconds.

Claim 16

The warning and brake light arrangement of claim 13, wherein the turn-off response time of said second light emitting means is at most about 40 nanoseconds.

Claim 17

The warning and brake light arrangement of claim 8, wherein said first light emitting means comprises an array of individual first LEDs and said light emitting means comprises an array of individual second LEDs, each interposed in alternating relation with individual ones of said first LEDs.

Claim 18

The warning and brake light arrangement of claim 8, wherein said first light emitting means comprises an array of clusters of first LEDs and said second light emitting means comprises an array of clusters of second LEDs wherein each cluster of second LEDs is interposed in alternating relation with individual clusters of said first LEDs.

Claim 19

The warning and brake light arrangement of claim 8, wherein said first and second light emitting means are arranged along parallel angled lines.

Claim 20

The warning and brake light arrangement of claim 8, wherein said first and second light emitting means are arranged in random fashion.

Claim 21

The warning and brake light arrangement of claim 8, wherein said first and second light emitting means are arranged along horizontal and vertical cross lines.
