A simple emergency lamp which does not require any special equipment; even a multimeter to assemble and use.
It is always better to connect a heat sink with BD 140.Before using the circuit out put of LM317 must be set to 7V by adjusting the potentiometer.
I am attaching the photos of my prototype in an National emergency light and also the PCB design.
You can search out different car DVD players in the market or online and then you can select the best one out of them by carefully considering the interiors of your cars. I like this circuit but I have a 12v ups battery how can I use the battery with this circuit without any problem.
Sir I need your advice at present I have an UPS which is no more in used for the Pc cos ever one in the house have got laptops, the UPS I want to used as an emergency light pls advice me as how many LED are require dim i for the 12v UPS and where can I get them or could you give me a circuit diagram where I can build it. Hi, the Automatic LED Emergency Circuit Diagram is auto charge (transistor LM317) circuit battery 6volt. I m working on the circuit 1 and I dont have much knowledge about it so can you please explain me the procedure, gladly i want to say your contribution towards this field and helping to beginners who are not very well known about circuits . Is the readymade PCB of the Auotmatic LED emergency light available for purchase in circuitstoday.
PCB & All component is available from you please sent cost if possible send sample to me for trial. My name is krishna and i want to do project about SMOKE DETECTOR SO Plz you send component list and also curcuit diagram along with simplied.

Any individual who can do a good quality soldering must be able to build this circuit successfully. This particular circuit has been kept so simple for people who has limited access to components or in other words this is an emergency light that you can build with minimum components. Puff to OFF LED circuit – A simple,hobby and more of a fun circuit where you can turn OFF an LED with a puff. Light Activated Switch – A circuit application to make a switch activated when light falls upon (and vice versa).
The only required adjustment is the preset which has to be set to ensure the LEDs just light up (it should be left at that position). I wanted to know if there is any equivalent and also how to give power supply indicate light please reply soon. The sturdy construction along with it's clean lines means it will look great for many years to come with very little maintenance. This can be easily accommodated in the defunct two 6 watt tube National Emergency Lamp or any PL tube type emergency lamp.
In addition to circuit diagram, He has shared photographs of the prototype he made in National emergency light and a PCB design. This can be easily accommodated in the defunct two 6 watt tube National Emergency Lamp or any PL tube type emergency lamp.


The auto function is taken care by MOSFET (the day light or with other light sources you do not require this light) hence an LDR(light dependent resistance) is used to sense the ambient light and to switch of the light.
It's also good for areas like industrial, hospitality, schools and universities for those on a tighter budget. This LED exit sign can give you the exit strategy you desire for almost any building that you may have. Deep discharge is taken care by the LED characteristic and over charge protection is taken care by the fixed voltage regulator.This uses a simple 3Pin fixed regulator which has a built in current limiting circuit.
Deep discharge is taken care by the LED characteristic and over charge protection is taken care by the fixed voltage regulator. 2 LEDs are used in series the dropping resistance is avoided and 2 LEDs light up with current by by a single LED,  by which energy is saved to a great extent. Slim profile thermoplastic LED exit sign offers long lamp life, energy efficiency and uniform illumination in an economical package. The 5mm LDR is just mounted on top of the emergency light as shown in the photograph. LDR is used to avoid it lighting up during day time or when the room lights are ON. 2 LEDs are used in series; the dropping resistance is avoided and 2 LEDs light up with current that is required for a single LED,  by which energy is saved to a great extent.
