Abstract

A programmable multi colored Light Emitting Diods (LEDs) rectangular display (panel) to replace the conventional traffic lights, the conventional traffic lights are generally vertically arranged consumes relatively alot of power and embedded into a bulky housing, the red light on top of the yellow light and the yellow light on top of the green light, the red light represents traffic must stop at an intersection, yellow light represents caution and green light represents traffic may pass, while in the new embodiment of the present invention a single rectangular LED display will provide the three traffic signal lights on the same area of the display consecutively,one after the other, in order to achieve this goal, the shapes of the three signal lights and the shapes of the arrow signal lights must be easily distinguishable for the color blind drivers.

Therefore the new invention provides a method and a system of updating the conventional traffic lights to have a less bulky, less power consumption and less expensive programmable LED traffic light display.

Claims

1. - A programmable multi color Light Emitting Diods (LED) display (panel) comprising:

A rectangular LED display with preferred dimensions of (12×

9)inches, wherein a matrix of LED clusters embedded into the rectangular housing of the display,each LED cluster comprising at least three colored LEDs, red, green and blue or yellow LED.

2. - The programmable LED display according to claim 1 wherein said clusters controlled by a computer traffic or a processor and energized to emit the desired light to create the desired images and shapes according the operating program of the LED display.

3. - The programmable LED display according to claim 1 wherein the face (screen) of the LED display comprising a matrix of multi color LEDs, and has preferable dimensions of (12×

9)inches and embedded into the housing of the LED display.

4. - The programmable LED display according to claim 2 wherein the matrix of the LEDs provides three traffic signal lights consecutively;

red light, green light and yellow light to control the traffic at an intersection, wherein the red light has a rectangular shape with preferable dimensions of (12×

9) inches and the green light has a circular shape with a preferable diameter of (9)inches in the center of the screen of the LED display,

furthermore, the yellow light has the shape of vertical yellow stripes with a preferable width of (1.5-2)inches and a preferable length of (9) inches,

moreover, the yellow signal light could have other desired patterns according the operating program.

5. - The programmable LED display according to claim 2 wherein the matrix of the LEDs provides two traffic arrow signal lights consecutively;

a green arrow light and a yellow arrow light wherein blank areas in its body.

6. - The programmable LED display according to claim 2 wherein the matrix of the LEDs provides a display capable of displaying colored traffic images and text messages such as the hand-figure, walking-figure, the speed limits around schools, . . . etc.

7. - The programmable LED display according to claim 4 wherein the matrix of the LEDs controlled by a processor or a traffic computer to provide programmable traffic lights consecutively with the desired duration, also to provide the desired traffic images and the desired traffic text messages according the operating program.

8. - The programmable LED display according to claim 1 wherein the rectangular housing comprising all the electronic components of the LED display such as the LEDs, microchips, memory, processor, . . . etc.

9. - The programmable LED display according to claim 1 wherein the rectangular housing has all the members needed to mount it on a cable or a pole at an intersection.

10. - The programmable LED display according to claim 1 wherein the rectangular housing has enough weight to withstand the wind while its hanging on a cable at an intersection.

11. - The programmable LED display according to claim 1 wherein the rain gaurd is attached to the front of the housing and extended forward from three sides;

the top and the two lateral sides to protect the screen of the LED display from the weather factors such as rain, snow, . . . etc. and provides shade to the screen to enhance the visibility of the traffic lights.

12. - The shape of a rectangular red light as a symbol of a STOP signal light.

13. - The shape of vertically striped yellow light on a dark background as a symbol of CAUTION (alerting) signal light.

14. - The shape of a circular green light on a dark background as a symbol of PASSING signal light.

15. - The method and the operating program of of displaying multiple images or shapes or text messages on the same screen of the LED display.

16. - The method and the example of using the LED display to display the traffic symbols and more particularly the hospital'"'"'s symbol H and its direction and the distance in miles to this hospital on the screen of the same LED display.

17. - A method and a system of the best configurations to use the LED display to replace the conventional vertical array of round traffic lights such as assigning a seperate LED display to replace a single vertical set of the conventional traffic lights and a seperate LED display to control the turning at an intersection.
