Abstract
A LED Traffic Light to aid people who have issues with color blindness. For the main LED traffic light, there is a solid matrix of LEDs on the complete face facing traffic. The light pattern displayed will indicate stop, caution, or go and the light patterns shown will differ for stop, caution, and go. Auxiliary lights can be employed with the main LED traffic light to indicate whether or not turns can be made.
Claims7
A LED traffic light system, comprising:
- a first LED traffic light having a housing, the housing having a LED matrix covering the full face of the housing;
- a programmable circuit board connected to a power source and to each of the LEDs contained in the LED matrix, the programmable circuit board programmed such that it can individually activate each of the LEDs in the LED matrix to display at least one indication of what action is permitted for a driver to take from viewing the LED matrix, where a first indication of what action is permitted displayed on the LED matrix of the first LED traffic light is to activate all of the LEDs in the LED matrix to display a first color;
- where a second indication of what action is permitted is to activate LEDs in the upper and lower portions of the LED matrix to display a second color, there being an area in the center of the LED matrix where the LEDs are unlit thereby showing a fourth color area between the second color upper and lower portions;
- and where a third indication of what action is permitted is to activate LEDs in the upper, middle, and lower portions of the LED matrix to display a third color, there being an area between each of the third color upper, middle, and lower portions where the LEDs therein are unlit, that area showing as a fourth color area.

A LED traffic light system, comprising:
- a first LED traffic light having a housing, the housing having a LED matrix covering the full face of the housing;
- a programmable circuit board connected to a power source and to each of the LEDs contained in the LED matrix, the programmable circuit board programmed such that it can individually activate each of the LEDs in the LED matrix to display at least one indication of what action is permitted for a driver to take from viewing the LED matrix, where a first indication of what action is permitted is to activate LEDs toward the top of the LED matrix to display a single arrow in a first color, the first color arrow indicating no turn permitted in the direction the arrow points, the remainder of the LEDs in the LED matrix being unlit;
- where a second indication of what action is permitted is to activate LEDs toward the top of the LED matrix to display two arrows in a second color, the second color arrows indicating turn permitted using caution in the direction the arrows point, the remainder of the LEDs in the LED matrix being unlit;
- and where a third indication of what action is permitted is to activate LEDs toward the top, middle, and bottom of the LED matrix to display three arrows in a third color, the third color arrows indicating turn permitted in the direction the arrows point, the remainder of the LEDs in the LED matrix being unlit.
