Making a 10/12 watt LED Lamp with 12 V Adapter
In this post I have explained the construction of a homemade 10 watt LED lamp using ready made 12 V SMPS adapter. The project was successfully built by Mr. Debabrata Mandal. In many of previous posts I have discussed the use of 1 watt white LEDs for making high efficiency LED lamps for implementing in […]
10 Automatic Emergency Light Circuit Diagrams Explain
In this article I have explained 10 simple automatic emergency light circuits using high bright LEDs. This circuit can be used during power failures and outdoors where any other source of power might be unavailable. What’s an Emergency Lamp An emergency light is a circuit which automatically switches ON a battery operated lamp as soon […]
1 watt LED Lamp Circuit Diagram using SMD LEDs
The post comprehensively discusses the construction procedure of a 1 watt LED lamp using SMD LEDs such as 3528 smd LEDs or 2214 SMD LEDs. I have explained the details. 1 Watt LED vs 3528 smd LEDs or 2214 SMD LEDs Today 1 watt LEDs are very popular and these are utilized in most LED lamp […]
0.6V to 6V/12V Boost Converter Circuit Diagram
In this post I have explained how to make a 0.6V to 6V or 12V boost converter circuit using a single chip MC74VHC1G14, which uses under 1V to operate. About the IC MC74VHC1G14 Normally, we all know that a silicon transistor would find it difficult functioning below 0.7V, unlike germanium counterparts which are capable of doing it […]
Simplest 100 Watt LED Bulb Circuit
In this article I have explained a very simple 100 watt LED bulb circuit using a few high voltage capacitors. The entire circuit could be built at a cost less than $25. I have already discussed many capacitive type of transformerless power supply circuits in this blog, however all these suffers from a couple of […]
