The Resistor R1 will act as a bleeder resistor (it will discharge the capacitor in the event of power failure or if LED fails).

#Build led light table series#

12 8mm LEDs are connected in series across the capacitor. The rectified output is given to a capacitor (C2). The other AC Input of the Bridge Rectifier is connected to the Neutral of the AC Power Supply.

NOTE: If you do not have a bridge rectifier, you can connect 4 PN Junction Diodes (like 1N4007) in full wave rectifier mode. To be on a safer side, connect a 100Ω 1W Resistor in series with the X – Rated Capacitor to act as a fuse (not shown in the circuit). The other end of the capacitor is connected to the AC input of a bridge rectifier. If this capacitor fails due to overvoltage, the fail will be a short and the excess current will blow the fuse and hence avoiding any electrical shocks.įirst, the main supply is given to the metal film capacitor. It is a metal film capacitor that is often used as a safety capacitor.Īn X – Rated capacitor is placed between the line and neutral. The main component of the Transformer Less Power Supply Design for the DIY LED Light Bulb is the X – Rated Capacitor. Component Description X – Rated Capacitor

NOTE: Use only metal film capacitor rated greater than equal to 400 for C1. B1 – Bridge Rectifier (4 Diodes can be connected in Full wave Rectifier mode).Components Required for DIY LED Light BulbĬomponents Required for DIY LED Light Bulb.Warning: Designing Transformer less power supply without the knowledge of how the components work can be fatal. You need to be very careful when working on AC Supply. Warning: This DIY LED Light Bulb will work directly from the main supply i.e. In fact, this type of power supply for LED Lamps is becoming more common (well, at least for lower wattage LEDs). Generally, we have two ways of designing the LED Driver: using a Switching mode power supply or a regular transformer based linear regulator.īut for this DIY LED light bulb, we will be designing a transformer less power supply to act as the LED Driver.

In this DIY LED Light Bulb, the design of the LED Driver is very important. In this project, we will try to make a DIY LED Light Bulb or a DIY LED Lamp using an old LED Lamp housing (case). With the cost of LED light bulbs becoming lower, people are gradually shifting towards LED Lamps in their homes and offices.
