Abstract: A light guide column is disposed on the top of a light source. The light guide column includes a column body, a cavity, a reflection structure and a micro-structure. The column body has a first end and a second end opposite to the first end. The cavity on the first end is for gathering the light source. The reflection structure is on the second end, when light emitted from the light source, a portion of the light reflected by the reflection structure to emit toward a lateral surface of the column body and others transmitted to the front side direction. The micro-structure is formed on the lateral surface of the column body can facilitate the emitting light from the column body uniformly.
