DEVICE FOR LIGHTING OF BUTTON

摘要

PURPOSE: A button lighting device is provided to execute functions of various vehicle electronic components in a space of restricted instrument panel by displaying at least two symbols in a button. CONSTITUTION: An optical source part(10) irradiates light. A supporting part(50) is arranged in the front of the optical source part. A semi-transparent layer(40) is laminated in the front of the supporting part. The semi-transparent layer blocks the external light. The semi-transparent layer transmits light radiated from the optical source part in a specific wavelength region. An opaque layer(20) is laminated in the front of the semi-transparent layer. The opaque layer blocks the light radiated from the optical source part. A masking part is formed in the opaque layer into a predetermined pattern. The masking part is composed of a transparent layer(30) transmitting the light radiated from the optical source part.
