This is a simple 230 V LED Driver circuit which is accomplished using a capacitor based power supply. This is a low cost and efficient circuit and can be used at homes. Here we design a simple circuit ...

An LED-driver reference design for an LED replacement of 100W incandescent bulbs has been introduced by Power Integrations, writes Richard WIlson. An LED-driver reference design for an LED replacement ...

This is the circuit diagram of bipolar LED Driver using microcontroller. Here we use an LED which has a forward voltage drop of 2.2V and hence can be biased using a 5V supply. This Bipolar LED Driver ...

In a previous article, I discussed LEDs in general and their properties. In this write-up, I want to give some examples of driving LEDs and comparing a few of the most commonly used methods. There is ...

Linear constantcurrent drivers, for instance, offer low EMI, low cost, and use only a few components. Many designers favor them for low-current applications where power loss is a minor concern. If ...

SOME MULTI-STRING LED MODULES come with a common-anode configuration. The commonanode connection reduces the number of wires between the LED module and its driver from 2N to N+1, where N is the number ...

Dimming LEDs is an important feature in many of today’s solid state lighting applications. While many implementations for dimming LEDs in the market today rely on PWM modulation of the LED driving ...

[Petteri Aimonen] created an omnidirectional LED safety light to cling to his child’s winter hat in an effort to increase visibility during the dark winter months, but the design is also great example ...

In this article, I would like to talk a little bit about LEDs, including why they will become the lighting source of choice, how to power them and also, how to protect them from the hazards they face ...

This “Product How-To” article focuses how to use a certain product in an embedded system and is written by a company representative. Light-emitting diodes (LEDs) have emerged in recent years as ...
