Optische Anzeige

摘要

The device (10) receives light from at least one light source (1) and illuminates a search and associated function symbol (3) in common. The illumination intensity and hence the light density of the light source is regulated depending on incident sunlight detected by an optoelectronic sensor (8). A pulse width modulated signal for controlling the light source is produced in a controller (7) by comparing the light source and ambient intensities
