The illuminated traffic bollard comprises a casing 10 and a base unit 20 wherein the base unit includes an array of Light Emitting Diodes (LEDs) 27 arranged so as to illuminate the casing to make it visible to traffic. The LEDs are preferably high flux LEDs and may be mounted on a circuit board that includes a heat dissipation system. The base unit may be formed from metal with the circuit board being in thermal contact with the base unit, and the LEDs may be arranged in a substantially circular configuration around the centre of the base unit. A transformer or regulator may be used to supply power to the LEDs at less than their maximum rated power. |
