A diode array with at least two image elements. The diode array includes a distribution transistor as well as a feed line for receiving a reference current and a first supply terminal coupled to the distribution transistor for supplying the distribution transistor. A diode and an input transistor are provided for each image element, each of which is coupled to the diode for supplying the diode. The distribution transistor forms a distribution current mirror with the respective input transistor of at least two image elements.

Diode array, arrangement, and system

In an embodiment a semiconductor component includes a laterally extending contact area laterally interrupted in such a way that material of the contact area laterally delimits at least one recess, the contact area configured to be at a potential, wherein at least one first recess is formed laterally as a circular ring around a lateral center point of the contact area, and wherein at least one second recess extends laterally in a straight line through the lateral center point of the contact area so that the contact area is divided by a corresponding recess into two halves which are not connected by material of the contact area.

Semiconductor component, system and method for checking a soldered joint

An arrangement for operating a diode array includes a plurality of LEDs. Each LED is assigned a respective sensor element which is configured to detect a characteristic value representative of a luminous flux of the respective LED. The arrangement also includes a respective supply input for providing a current for light-emitting operation of the respective LED. The arrangement further includes in each case a control unit which is coupled on the input side to the respective supply input and the respective sensor element and on the output side to the respective LED and is configured to control the current for light-emitting operation of the respective LED as a function of the corresponding characteristic value. The arrangement additionally includes a respective supply input for providing a current for light-emitting operation of the respective LED.
