Abstract
The utility model discloses a light-emitting diode (LED) street lamp which comprises a lamp holder, a lamp tail, a lamp body connecting piece and module type LED lamp sets with waterproof performance. The lamp holder and the lamp tail are respectively connected at two ends of the lamp body connecting piece. At least one module type LED lamp set is installed on the lamp body connecting piece at intervals and located between the lamp holder and the lamp tail. An interval is formed between each two adjacent module type LED lamp sets. The principle of cross ventilation is conformed to, effective heat dissipation areas are increased, and heat resistance is reduced. Meanwhile, the lamp body connecting piece is an aluminum alloy connecting piece. Heat quantity generated by the module type LED lamp sets can be dissipated through the lamp body connecting piece, the heat dissipation areas are further increased, a heat dissipation effect is improved, and service life is prolonged. In addition, the lamp holder and the lamp tail are respectively heat resisting light plastic shell bodies, the weight of the LED street lamp is lightened, and production cost is reduced.
