Appl. No.:

8/877526

Assignee:

Traffic Technology, Inc. - Scottsdale AZ

International Classification:

G08G 1095

US Classification:

34081565

Abstract:

LED traffic light 30 having a housing 39 that holds at least three different signal lights 32, 34, and 36. The three lights 32, 34, and 36 are each embedded in an opening 50 of housing 39. The LEDs for traffic signal lights 32, 34, and 36 are arranged in symbolic shapes (i. e. universal symbols or words) that further represent one of the traffic signals. Red signal light 32 has red LEDs 31 arranged in an octagon shape (i. e. stop sign shape), and yellow or amber signal light 34 has yellow LEDs 33 arranged in a triangle shape (i. e. caution sign shape). Green signal light 36 has green LEDs 35 arranged in a circular shape. The preferred embodiment is a single lens traffic light 40 having a housing 49 that provides at least three signal lights 42, 44, and 46. The three signal lights 42, 44, and 46 are all embedded in a single opening 50 of housing 49. The LEDs for signal lights 42, 44, and 46 are arranged in a generally common area that allows activation and display of one of the signal lights in a corresponding symbolic shape (i. e.

Abstract:

A new embodiment LED traffic light 40 having a housing 49 that provides at least three signal lights 42, 44, and 46. The three signal lights 42, 44, and 46 are all embedded in a single opening 50 of housing 49. The LEDs for signal lights 42, 44, and 46 are arranged in a generally common area that allows activation and display of one of the signal lights in a corresponding symbolic shape (i. e. universal symbol or words). Red signal light 42 has red LEDs 41 spread out and arranged in an octagon shape (i. e. stop sign shape). From a distance or afar, however, it may be difficult for persons to distinguish between the octagon shape and the circular shape (i. e. stop and go signals respectively). Therefore, a border 52 of contrasting color LEDs 54 (i. e. different color other than the color of the octagon) is placed around the octagon shape and illuminated to further enhance and define the stop sign or octagon shape thereof.
