VARIABLE SYSMBOL DISPLAYING SWITCH UNIT AND METHOD FOR CONTROLLING THE SAME

摘要

PURPOSE: A variable symbol display unit and a control method thereof are provided to implement a quick operation by using the light source control of a suitable light source part according to a driving environment. CONSTITUTION: A circuit board is fixed to a housing. A first wavelength light source(310) is arranged on the circuit board. The first wavelength light source outputs first wavelength light. A second wavelength light source(320) outputs second wavelength light. A control part(20) outputs a light source control signal to a light source part. [Reference numerals] (20) Control part; (30) Storage part; (310) First wavelength light source; (320) Second wavelength light source; (510) Proximity sensor; (520) Illumination sensor; (530) Difference speed sensor; (600) Switching unit; (700) Indoor lighting switch
