1. A floor-type walking signal device installed by being buried in the ground between a road and a sidewalk, comprising:
a body unit including a base surface inclined upward from one side to the other side;
a light emitting diode (LED) module which is installed on the base surface of the body unit and on which a plurality of LED devices configured to generate signaling light are disposed in a matrix; and
a reflector disposed on an upper portion of the LED module and including a plurality of reflective surfaces corresponding to each of the plurality of LED devices,
wherein the plurality of reflective surfaces are classified in a unit of column and separately defined as first to nth (n is a natural number) column reflective surface groups sequentially from a position close to one side to a position far from the one side,
each of the first to nth column reflective surface groups includes a first wall surface and a second wall surface disposed at intervals in a width direction of the reflector,
a first virtual line extending downward from the first wall surface and a second virtual line extending downward from the second wall surface form a virtual angle at an intersection point, and
at least two of the first to nth column reflective surface groups have different virtual angles, and as the column reflective surface group is closer to the one side, the virtual angle is formed to be smaller.
