The invention discloses an LED lamp. The LED lamp comprises a fixed base; an accommodating cavity surrounded by an upper cavity and a lower cavity is fixedly arranged on the fixed base; two solar panels are symmetrically arranged on two sides of the accommodating cavity on the fixed base; battery modules electrically connected with the solar panels are arranged in the lower cavity; a main controlsystem is arranged in the upper cavity; the main control system comprises a microprocessor and a timing module; a light transmission column is fixedly mounted in the upper cavity; multiple LED lamps are longitudinally arranged in the light transmission column; multiple signers are longitudinally arranged on the light transmission column; the battery modules are connected with the timing module andan input end of the microprocessor; and an output end of the microprocessor is connected with the LED lamps and the signers. The LED lamp uses the solar panels for power supply to achieve energy conservation and environmental protection; the timing module and the microprocessor intelligently control opening and closing of the LED lamp; the signers of a liquid crystal display module display road information to achieve examination of road conditions at night; and the LED lamp is powerful in function, simple in structure, beautiful in appearance and broad in application prospect.
