US Patent Number 7,960,921 - CURRENT REGULATOR APPARATUS AND DEVICES- covers the electrical current regulation for Nexxus' Array LED lamps, which allows the LED light source to sense ambient thermal changes and adjust current levels and light output to maintain proper thermal performance of the product.
The latest constant current regulator ICs, such as those from ON Semiconductor, can accommodate supply voltages in excess of 40 V and down to 3 V, offer current outputs from 20 mA to 1.5 A, and are fully compatible with step-down (buck), step-up (boost), step-up/down (buck/boost) or SEPIC topologies.
According to the company, feedback voltage is used to regulate the average current through the LED string in a constant current regulator configuration and also allows the use of a smaller sense resistor.

The BoE's Financial Policy Committee (FPC), which is expected to take charge from next year, has urged the current regulator to reassess whether banks' capital properly reflects the risk of loans going sour and future fines for misconduct.
Leadis' LDS8160 solid-state lighting driver (SSLD) is intended to optimize the LED drive current for desirable luminosity-over-temperature performance, and includes a temperature compensation engine and current regulator. The former monitors the in-situ temperature on each LED and independently optimizes the LED current for best luminosity versus temperature performance.
