成果简介	NOVELTY - The circuit (102) has an input voltage feedback module (104) for detecting output direct current (DC) voltage proportional to input alternating current (AC) voltage supplied to a rectifier circuit of a LED driver (114). A current injection setting module (106) sets a threshold voltage based on the input DC voltage. A variable current setting module varies an output current of the LED driver. A current sensing module (110) senses an input current. A current injection module (112) increases the input current when the input direct current voltage is detected above the threshold voltage. The injection module comprises a deregulation metal oxide silicon field effect transistor. USE - Variable current transmission (VCT) circuit for adjusting lumen output of an LED driver (claimed) of a solid-state lighting (SSL). ADVANTAGE - The current injection module increases the input current when the input DC voltage is detected above the threshold voltage, thus reducing the complexity in LED drivers and providing reduced small signal-to-noise (SKU) which can be employed across a variety of LED luminaries. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for adjusting lumen output of an LED load. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a VCT circuit. 102VCT circuit 104Input voltage feedback module 106Current injection setting module 110Current sensing module 112Current injection module 114LED driver
