Traffic signal lamp

The utility model relates to the traffic signal lamp of the traffic control system, comprising a signal lamp body of which the front part is provided with a light-emitting module which adopts light-emitting diodes arranged in a dot matrix to be light-emitting source, and a control circuit is arranged in the signal lamp body. The traffic signal lamp is characterized in that the diameters of the light-emitting diodes are between 7. 5mm and 9. 5mm, the light-emitting diodes have elliptical light-emitting heads, the diameters of the light-emitting diodes are 8mm, the diameters of the long shafts of the elliptical light-emitting heads of the light-emitting diodes are 8. 5mm, and the diameters of the short shafts are 8mm; the central line of the diverging light of the light-emitting diodes is not coincided or parallel to the process central line of the light-emitting diodes to form an included angle which is larger than or equal to 10 degrees and is smaller than or equal to 30 degrees. The utility model can raise the light-emitting power and increases the light intensity, which simultaneously ensures the observing integration effect of the human eyes, having high using efficiency and strong practicality.
