Neon Lamps – Working and Application Circuits
A neon lamp is a glow lamp made up of a glass cover, fixed with a pair of segregated electrodes and containing an inert gas (neon or argon). The main application of a neon lamp is in the form of indicator lamps or pilot lamps. When supplied with a low voltage, the resistance between the […]
Transformerless Current-Controlled LED Bulb Circuits you can Build at Home
In this post I have elaborately explained how to build simple transformerless LED bulb circuits using many LEDs in series and powering them through current controlled capacitive power supply circuit. Warning: Circuits I have explained below are not isolated from mains AC, and therefore are extremely dangerous to touch in the powered and open condition. […]
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 […]
