Description

technical field

[0001] The invention relates to a transmitting device for an optical sensing device of a motor vehicle having at least one light source unit. The transmitting device also comprises optical means which influence the beam shape of the light emitted by the at least one light source unit. By means of the transmitting device, light can be transmitted into the surroundings of the motor vehicle. Furthermore, the invention relates to an optical sensing device with a transmitting device and a motor vehicle with an optical sensing device. Background technique

[0002] Prior art transmitting devices are relatively large, in particular because the housing for the optics is relatively large. Furthermore, the transmitting device usually includes a heat-conducting copper plate, on which the components of the transmitting device are arranged. Furthermore, the various parts of the transmitting device are usually connected together, in particular screwed together, so that t...

Embodiment Construction

[0033] figure 1 A motor vehicle 1 according to an embodiment of the invention is shown. Motor vehicle 1 is designed as a passenger car in the exemplary embodiment. Motor vehicle 1 includes a driver assistance system 2 . With the driver assistance system 2 it is possible, for example, to detect an object 3 located in the environment 4 of the motor vehicle 1 . In particular, the distance between the motor vehicle 1 and the object 3 can be determined by the driver assistance system 2 .

[0034] Driver assistance system 2 includes at least one optical detection device 5 . The optical detection device 5 can be implemented as a lidar sensor or as a laser scanner. The optical sensing device 5 includes a transmitting device 6 with which light 8 can be emitted. The sending device 6 comprises in particular a plurality of light elements 35 ( Figure 5 ), which are especially formed as VCSEL (Vertical Cavity Surface Emitting Laser) laser diodes. The optical detection device 5 is ar...
