4 Automatic Staircase Lamp Controller Circuits Explained
In this post I have explained 4 innovative automatic staircase lamp controller circuits which will automatically switch ON and OFF the staircase lamps in response to an external trigger. We will discuss 4 concepts here, which are as follows: 1) Automatic Staircase Lamp Circuit using PIR The first automatic staircase light circuit describes a simple […]
How to Make Car LED Bulb Circuit
Typically all car turn signal lamps are around 12 to 20 watt rated which are traditionally incandescent bulb types and produce much lower light intensities compared to LED lights. Here I have explained how these lamps can be replaced with high efficiency, high intensity car LED bulbs. LED Car Bulb Design The image below shows […]
Using Aluminum Strip Heatsink for Hi-watt LEDs instead of PCB
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 […]
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 […]
