LED-based bulbs that replace their incandescent counterparts require a significant amount of engineering (Fig. 1). In the 60 W range the LED driver board can take up about 15% of the overall cost of ...
High-power LEDs challenge electronics engineers to design accurate and efficient, yet simple, driver circuits. Conventionally, driving high-power strings with accurate current requires dedicated ...
The high efficiency of more than 93 % at heavy load with 1 Ampere and three LEDs in series as well as 85 % at light load with 0.35 Ampere and one LED allows the usage of a very small PCB. The LED ...
Lumissil Microsystems has created a pair of LED drivers that include a 32MHz 8051 microcontroller. “These new controllers enable lighting engineers to create customised dynamic LED lighting animations ...
The automotive industry makes extensive use of light-emitting diodes (LEDs) in high-beam headlights, brake and position lights, and side and rear direction lights. In an LED driver design, the ...
