Abstract

An adaptive lighting apparatus ( 1 ) for high-speed image recordings for an object ( 2 ) uses a number of high-speed image recording devices ( 30, 31, 32 ), with a number of LED lighting units ( 10 - 18 ) having LED illuminants ( 100 - 104 ) that can emit light to light the object ( 2 ) during operation. An actuator actuates the LED lighting units ( 10 - 18 ) individually or in groups. A control device ( 4 ) controls the actuator, and has a memory that stores parameter sets for actuating the LED lighting units ( 10 - 18 ) for retrieval. An evaluation device calibrates the adaptive lighting apparatus ( 1 ) and then captures and evaluates the images of the object ( 2 ) that are recorded by the high-speed image recording devices ( 30, 31, 32 ) and calculates therefrom the parameter sets for adaptively actuating the LED lighting units ( 10 - 18 ).

First claim

What is claimed:

1. An adaptive lighting apparatus for use with a high-speed image recording device, the adaptive lighting apparatus comprising:
a multiplicity of LED lighting units, each LED lighting unit having a multiplicity of LED illuminants that can emit enough light to sufficiently illuminate a target object during operation of a high-speed image recording device configured to record hundreds of images of the target object per second;

an actuator for actuating the…
