Whenever we come across using 1 watt LEDs or other higher watt LEDs, we are always advised to use high grade aluminum based heatsinks for safeguarding the LEDs from heat, and for acquiring optimal performance from them. Double Side PCB can be Costly However as we all know such PCBs are highly costly and could […]
Newly Updated Circuit Projects:
110V Compact LED Tubelight Circuit
In this article I have explained a simple single IC LED tube ligt circuit applicable for 110V/120V AC inputs. The circuit uses 30 numbers of 1 watt LEDs, and also includes a voltage and current control features. In my previous post I discussed the IC TL783 which is a 1.25V to 120V variable DC regulator […]
5630 SMD LED Driver/Tube light Circuit
In this post I have explained a simple transformerless SMD 5630 type LED tube light circuit which can be built by anybody for illuminating home interior cheaply. The idea was requested by Mr. Smeet. Technical Specifications I am a very big fan of your website and it has been much helpful to me in my […]
IC 555 Automatic Emergency Light Circuit
The discussed 2 simple IC 555 based emergency lamp system employs just a single IC 555 and yet is able to switch more than 20 LEDs directly, it will illuminate the LEDs only during the absence of mains power and ambient light. 1) Using IC 555 as a Comparator The proposed circuit is not only […]
2 Best Current Limiter Circuits Explained
In this post I have explained 2 simple universal current controller circuits which can be used for safely operating any desired high watt LED. The universal high watt LED current limiter circuit explained here can be integrated with any crude DC supply source for getting an outstanding over current protection for the connected high watt […]
How to Connect 5mm LEDs to a 3.7V Li-Ion Cell
In this article I have explained regarding how to connect and illuminate a few 5mm LEDs using a 3.7V Li-Ion cell, normally used in cell phones. I keep receiving requests from the readers who seem confused with the connection details of 5mm LEds with a 3.7V Li-ion cell. The requests inspired me to write this […]
