The invention discloses an LED daytime travelling lamp which comprises lamp shades, an LED circuit board, a power supply board, a reflecting mirror and lamp housings; more than one LED light source and an insert are arranged on the LED circuit board; a plurality of components and a protective cover are arranged on the power supply board; and the LED circuit board is connected with the protective cover through the insert, and thus puts through the power supply board. The LED daytime travelling lamp is characterized in that an ornament cover is fixedly arranged on the reflecting mirror, and the ornament cover can be arranged by fasteners, screws and the like. According to the LED daytime travelling lamp, LED lamp beads are arranged at the bottom of a collecting lens, and light rays emitted by LEDs are collected by light harvesting holes, so that the light ray direction is changed, the loss of the light rays is reduced, then harvested light is uniformly diffused and emitted through a divergent mirror, and the standard of the LED daytime travelling lamp is met; the structure is small and simple; the luminous efficiency is high; the collecting lens can be arranged and set according to practical requirements; and the applicability is high.
