The utility model discloses an engineering brightening dimming device in the technical field of engineering brightening. The lighting device comprises a base, a supporting rod and a lighting mechanismwhich are sequentially arranged from bottom to top. The lighting mechanism comprises a fixing box, a lower reflecting plate, an upper reflecting plate and a side reflecting plate are arranged on thefixed box; according to the LED street lamp, under the combined action of the upper reflecting plate, the lower reflecting plate and the side reflecting plates, light of the illuminating lamp is reflected, and the spotlighting effect of the illuminating lamp is achieved; the arc-shaped plates on the corresponding sides are driven by the driving assemblies to rotate upwards, so that the lamp holderand the illuminating lamp are driven to move upwards, meanwhile, through corresponding connection of the driving assemblies and the adjusting assemblies, the rotating rods drive the upper light reflecting plates on the corresp
