Lamps and Lights

You might have probably come across these fantastic high power, high efficiency LED modules and wondered how do you make these? Here I have explained how to make a 100 watt LED flashlight out of it? Introduction The article revises the datasheet of this LED module and explains a simple driver circuit which can be […]

In this article I have explained how to make a sequential LED array light circuit with an sequentially illuminating LED forming a bar graph kind of LED formation. Introduction In this article I have explained a simple method of making an incremental LED light using the IC 4017, which is rather equipped with specifications not […]

An LED tube-light is lighting device built using high efficiency LEDs for illuminating a premise where it is installed, through the available AC mains supply. In this post I have explained the complete construction details of a simple LED light tube light circuit using 20 mA, 5 mm high bright white LEDs. The circuit can […]

This transformerless solid-state automatic night lamp operates without using bulky transformer, and automatically switches ON some LEDs during night, and switches them OFF during day. In this post I have explained how to make a transformerless automatic darkness activated LED lamp circuit, using a couple of transistors and capacitive based power supply, eliminating the use […]

This 4 watt LED driver is a device that will illuminate a 4 watt LED safely through a constant current circuit using the IC LM338. The IC LM338 as we know is a highly versatile device when it comes to controlling voltages and current levels. Circuit Configuration In the present design, the device is configured […]

An infrared flood light is a circuit that creates an illumination over a wide range of area using infrared frequency. This infrared illuminated area can be perfectly visualized through specialized infrared gasses and IR cameras, but can be totally invisible to naked eye. In this post we study a simple infra red based flood light […]
