The present invention provides an LED street lamp and includes LED light sources and a reflector assembly. The reflector assembly includes a pair of symmetrically arranged curved reflectors, standing back to back. The curved reflectors are respectively designed as continuous parabolic curved surfaces in a direction parallel to the road surface to reflect the light emitted from the LED light sources. Therefore, after being reflected, the light is radiated to a predetermined area in the direction parallel to the road surface. The LED street lamp can in one instance reflect most of the light emitted from the LED light sources within the predetermined area on the road surface. Therefore, the present invention can improve light efficiency of a system in one embodiment, and satisfy a requirement of an actual road for light distribution in another embodiment. |
