The utility model provides a light guiding device which comprises a light source, light guide flexible glue, a fixed bracket and a PCB (printed circuit board), wherein the light guide flexible glue mainly consists of a PU (Poly Urethane) material; the light source and the PCB are connected with the fixed bracket; a lead of the light source is electrically connected with the PCB; and a light emitting part of the light source is connected with the light guide flexible glue. The light guiding device has the beneficial effects that a novel material utilized in the utility model has the following characteristics that due to the density and the characteristics of the material, light can be effectively scattered out from the light source on a light guide bar and can be sufficiently transmitted for a certain length, so that the visibility of the light guide bar is high, that is, the light source, such as an LED (light-emitting diode), has excellent scattering effect from one side to the other side; the material of the light guide bar has high plasticity, so that the light can be spread in different media form/shape, and thus, the light guiding device can be used/be suitable for different objects/surfaces; and the material of the light guide bar is soft and is a flectional media, so that 360 DEG of visible light can be established according to the forms of the objects.
