Abstract

The invention relates to a millimeter wave transmitting radar logo lamp. The vehicle logo lamp mainly comprises a vehicle logo outer mask, a light guide plate, a vehicle logo lamp PCBA (Printed Circuit Board Assembly) and a vehicle logo lamp shell, a dotted luminous source is arranged on the vehicle logo lamp PCBA; the point-shaped luminous sources are aligned with the light incident surface of the light guide plate; the vehicle logo lamp outer face cover, the light guide plate and the vehicle logo lamp shell are tightly matched in a radar penetrating area. The light guide plate comprises a light guide section and a light diffusion section; one end surface of the light guide section is provided with a light incident surface; a bending part is arranged between the light incident surface and the light emergent surface; the light emitting surface corresponds to the transparent area with the specific pattern on the outer cover of the vehicle logo lamp; the front side of the light emitting direction of the astigmatism section is printed with astigmatism ink on the surface of the astigmatism section at a position corresponding to the transparent area with the specific pattern, and the back side of the astigmatism section is printed or etched by laser; according to the invention, the problem of sharing the millimeter wave radar vehicle logo and the vehicle logo lamp is solved, and the vehicle logo lamp can be simply assembled in a structure space as small as possible.

Description

technical field [0001] The invention relates to an illuminating device used for a millimeter-wave radar-transmitting exterior decorative piece of a motor vehicle, especially a passenger vehicle, in particular to a millimeter-wave radar-transmitting vehicle sign lamp. Background technique [0002] Today, L2 assisted driving is gradually improving, and it is increasingly used in the integration of millimeter-wave radars in the front of vehicles and the integration of lighting surfaces in exterior trim parts. In particular, linear lighting through millimeter-wave radar, that is, a lighting device in which a uniform lighting surface extending along one or more light guide devices passes through external decorative parts and passes through lighting strips with specific patterns. [0003] As is known in the prior art, the millimeter-wave radar on the front side of the vehicle is usually arranged at the rear of the vehicle logo to cover, and the vehicle logo light will occupy this ...
