Operating device for automobile heating and/or air-conditioning has display field provided by insert in front plate illuminated using non-visible electromagnetic radiation via wavelength converter

摘要

The operating device has a front plate (14) provided with at least one opening (20) between its front and rear sides (16,18), fitted with an insert (22) provided with a rear-illuminated display field (38). At least one light source (36) provides electromagnetic radiation in the non-visible wavelength range, directed onto the rear of the front plate and converted into visible radiation via a converter element (42) provided by the insert at the rear of the display field.
