A light module has a carrier with a circuit die. On the top side of the carrier, a light-emitting diode die and a charge store component are electrically connected to the conduction path terminal areas of a transistor by means of die-to-die bondings. The electrical connection between the two dies and the conduction path of the transistor is as short as possible. A terminal area is situated in each case on the top side of the two dies, which terminal areas are connected to one another using a first bonding wire. The charge store component is charged by means of a charging circuit which is electrically connected to the charge store component via a second bonding wire. The second bonding wire is longer than the first bonding wire. The light module may be part of a LIDAR apparatus.

Light module and LIDAR apparatus having at least one light module of this type

A lidar receiver circuit for receiving optical signals using photodetectors to detect events or objects in the surrounding area, with a redundancy of receiver circuits for reducing failure probability, including a photodetector array for receiving optical signals and outputting a measurement signal, wherein the photodetectors are arranged as a two-dimensional matrix, a plurality of receiver circuits for receiving the measurement signal; a plurality of multiplexers, which are electrically arranged between the array and circuits and are connected thereto; wherein at least one of the multiplexers is connected to a column of photodetectors and at least two receiver circuits; each circuit is configured to receive and process the measurement signals of a column; a column of photodetectors is assigned to each receiver circuit by default; and the multiplexers connect a column to a receiver circuit other than the receiver circuit, which is assigned to the column of photodetectors by default.

Lidar receiver circuit having redundancy to bypass failure

A timing generator as master clock for an electronic circuit includes a coarse code and a plurality of fine codes, has a ring oscillator with an uneven number n of delay elements, each of which has a delay output at which clock signal is present; clock dividers which are connected to the delay outputs and at whose output a clock divider output signal is output; start circuit for generating initialization signal to trigger clock dividers, and clock generator that further processes clock signal and generates a coarse code, and an output at which generated timestamp is output, wherein the fine codes of timestamp are formed from clock divider output signals of the clock dividers, and the coarse code and the fine codes contain redundant information that a time shift of the fine codes relative to the coarse code by at most (n&#x2212;1)/2 time differences results in a correct timestamp.
