Low power LED AC Lamp

Introduction
This lamp use two circuits one is converts AC voltage into DC voltage and second is LEDs circuit. One disadvantage of this circuit is that you can connect more than 20 LEDs in series and parallel combination. It is use as a night lamp or in small room. It’s consume very less power.

Making connection for AC lamp

You can take component as per given component list and first you should identify polarity of all component and then components are mounted on Printed Circuit Board (PCB) as per given circuit diagram. You should take care while soldering and plugging into 230v.

Working:-

We give 230 volt input to the circuit in circuit reduce current as well as voltage this given to diode bridge circuit. The diode bridge circuit main function is its convert AC voltage into DC voltage and that DC volt given to LED. The LED connect in combination of series and parallel form, If one LED burn then other LEDs will be not problem

Features

1) It operated on 230v AC.
2) Low power consumption up to 3 watt.
3) It works continuously.
4) If any there are any changes in main supply that time there is no effect on LED lamp.

Emergency Lamp

Introduction
This circuit consume very less power than CFL lamp and incandescent lamp. The lamp take 6 hours for battery charger and you get 25 hrs backup. Lamp use for farmer on field and best for rural and urban areas.
Making connection for lamp
You can take component as per given part list and first you should identify polarity of all component and then components mounted on Printed Circuit Board (PCB) as per given circuit diagram. When complete soldering then You can connect LED lamp to one side of switch and another side of switch connect side search light and middle terminal of switch connect to battery positive and charger output. The make connection for charger, output from transformer to separate two wire and this wire connect to separate of two diode and this two diode negative will be combine and connect to switch. The separate one diode connect to one wire of transformer for mains ON.

Features

1) It is operates on 6V (4.5AH) battery.
2) Low power consumption. Consumes up to 1.5watt.
3) It gives backup for 25 hours.

LED Charger

A 6V charger was designed and it is a product of Fablab. It is very useful to charge 6v battery. The cost of charger is Rs.85.

LED Light

A 230 volt tube light like LED is also available. The cost of tube light is about Rs.110. It consumes about 5w of power.

TEPOY

The tepoy was designed and cut on Torchmate. It is the first product on Torchmate. The cost of tepoy is 300Rs.

There is an engraved design on the tepoy and will be make it more attractive thing as we add more skills.

Cutter

We have continued with our innovative ideas and designed a unique metal cutter. The cutter was designed by Ram Chougule one of our DBRT ex-student. One can cut all types of metals and angles with the cutter

CFL

This is another product of fablab. The step down circut is assamble in this. Most CFL's available in market are use & throw. We applied a circut in adapter we have given the freedom to same adapter for many tubes.
