Abstract

A light-emitting diode road lamp structure includes a seat body and a plurality of tube bodies. The seat body includes an accommodation space to accommodate a circuit unit. The tube bodies are juxtaposedly connected to an outside of the seat body, a plurality of light-emitting (LED) units accommodated in the tube bodies are electrically connected to the circuit unit, and an interspace is formed between each of the tube bodies and the tube body abutted therewith, thereby providing the road lamp with a better heat-dissipation efficiency by the air flow passing through the interspace, maintaining the luminous efficiency of the LED units, and extending the life span of the LED units.
