In a previous article, I discussed LEDs in general ... is essentially an open-loop control and there is no feedback from the circuit to the user other than varying brightness.

Even if you are designing a microcontroller-based LED display system, often it may calls for a manual option to control brightness of the ... As a bonus, you can build your own LED display brightness ...

As soon as I applied LED power, the brightness blinded me — much brighter than the original T20 fluorescent tube, so I knew immediately that a dimmer control was required ... flicker-free light. Many ...

Guest columnist Faraz Hasan, marketing and business development manager at Tyco Electronics Circuit Protection Products says that LEDs can require overcurrent protection despite built-in safety ...

BCM does the same thing as PWM, it turns the LED on and off very rapidly so that your eye cannot detect a flicker. The brightness level is a result of the average amount of time the LED is on ...

High-brightness LEDs, with independent delay and duration, find use in a visual-inspection application. This circuit is not complex, but it saved the day in an application involving visual inspection ...

Lighting a string of LEDs at a constant brightness requires ... of the series LEDs or its wiring, an open load condition can be created. In this situation, the voltage across the current sense ...
