Abstract
A light guiding column is with a waterproofing function and for guiding light emitted from a light emitting component to outside of a case. The light emitting component is disposed on a base plate. The base plate is disposed inside the case. The light guiding column includes a first end portion and a second end portion. The first end portion passes through a through hole formed on the case in a tight-fitting manner. The second end portion is opposite to the first end portion and clamped between the base plate and the case in a tight-fitting manner. A chamber is formed between the second end portion and the base plate, and the light emitting component is accommodated inside the chamber. The present invention can reduce an amount of components for assembly to reduce manufacturing cost and difficulty in assembly.
