The invention discloses a condensing garden streetlamp. The condensing garden streetlamp comprises a lamp pole, a lamp holder, a lampshade and a bulb. The lamp holder is fixed above the lamp pole; thebulb is located in the lampshade; the lampshade is fixed under the lamp holder; the lampshade comprises a side wall located on the side face, a bottom wall and an inclined wall below; the inclined wall inclines downward and is connected to the side wall and the bottom wall; the bottom wall, the inclined wall and the side wall form the integrally formed lampshade; filling glass for refracting raysdownward is arranged on the inner side surfaces of the bottom wall and the inclined wall; the filling glass and the lampshade are integrally formed; the upper surface of the filling glass is a concave spherical concave surface; the bulb is located above the concave surface; the side wall is a diffractive transmitting coarse surface; and the bottom wall and the inclined wall are smooth transmitting planes. The rays of the bulb are refracted downward by way of refraction, and rays which are not cut down are illuminated to a pavement through the smooth transmitting bottom wall and inclined wallto form a cone-shaped illuminating region, thereby providing sufficient illuminating brightness for the road.
