    摘要: An exemplary street lamp includes a solid-state light source and a light guiding plate. The light source is used to emit light to illuminate a portion of the traffic lane. The illuminated portion includes a first section and a second section at opposite sides of the projection of the light source on the traffic lane. The solid-state light source defines a central axis perpendicular to a lengthwise direction of the traffic lane. The plate includes a light incident surface and a light output surface at opposite sides thereof. The plate is used to deviate the light from the light source. In this manner, a maximum light intensity in the first section is less than or equal to 60 percent of a maximum light intensity in the second section.
