Patent ID: 8541951

Claim:
An LED system for coupling to an AC power source comprising: a rectifier module being electrically coupled to the AC power source, the rectifier module being configured to provide a rectified output; a first array of LED devices, the first array of LED devices being electrically coupled to the rectifier module and to receive the rectified output; a second array of LED devices electrically coupled to the first array of LED devices; a current monitor module electrically coupled to the first array and second array of LED devices, the current monitor module being configured to determine a first current level using a drawn current level signal associated with the first array of LED devices and a second current level using a reference current level signal associated with the second array of LED devices; and a signal compensating module electrically coupled to the current monitor module, the signal compensating module being configured to generate a first compensation factor signal based on a difference between the first current level and a first reference current level.
