In many lighting applications, measuring the relative intensity of two light sources is more important than measuring their individual intensity. This ensures that two light sources shine with the ...

Lighting a string of LEDs at a constant brightness requires driving it with a regulated current. A boost converter is commonly used to step up the voltage to a level high enough to bias the LEDs on ...

This is a very simple touch light switch circuit that uses the 4011 IC, one transistor and a relay. The C1 capacitor stores the switching state at a certain time and is charged or discharged according ...

In the realm of lighting control, Aputure has launched its Sidus Ecosystem, featuring Sidus Link Pro and Sidus One to interact with any kind of lighting setup. The system promises to streamline ...

The following circuit uses a low-power CMOS comparator and an LED to indicate low-battery voltage without causing excessive current drain. To view the application note, click on the URL below. Circuit ...
