The present invention relates to an LED lighting device for crosswalk and an assembling method thereof. The device includes a reflector having a L-shaped curved body in a symmetrical structure, and forming a free curved surface by an aspherical surface to reflect emitted light of an LED to a target surface; a heat sink enabling the internal combination of the reflector, performing a function of a body case, and performing a radiation function; the LED installed in the heat sink, and making the emitted light reflected from the free curved surface of the reflector; and a cover protecting the LED and the reflector by being combined with a lower surface of the heat sink, and transmitting the controlled light of the LED, heading for the target surface by being reflected by the reflector. The emitted light of the LED is controlled by using an indirect lighting method without exposing a light source, and therefore, light pollution and glare problems are improved and a perfect waterproof function is formed. |
