摘要： An LED lamp color control system and method including an LED lamp having an LED controller 58; and a plurality of LED channels 60 operably connected to the LED controller 58, each of the plurality of LED channels 60 having a channel switch 62 in series with at least one shunted LED circuit 83, the shunted LED circuit 83 having a shunt switch 68 in parallel with an LED source 80. The LED controller 58 determines whether the LED source 80 is in a feedback controllable range, stores measured optical flux for the LED source 80 when the LED source 80 is in the feedback controllable range, and bypasses storing the measured optical flux when the LED source 80 is not in the feedback controllable range.

摘要： A LED based lighting system (20) employs a LED load temperature sensor (40) for generating a temperature-sensing signal (TSS) indicative of an operational temperature of the LED load (10), a LED current sensor (50) for generating a current-sensing signal (CSS) indicative of a flow of the LED current (ILED) through the LED load (10), and a LED driver (30) for regulating the flow of the LED current (ILED) through the LED load (10) as a function a mixture of the current-sensing signal (CSS) and the temperature-sensing signal (TSS). The system (20) can further employ a driver disable notifier (80) and a LED driver disabler (90), or alternatively, a fuse network (100) for disabling the LED driver (30) upon a detection of a fault condition of the system (20).
