LED circuits
LED circuits - related electronic projects and circuit diagrams (schematics), this helps you finding desired informations and facilitates your site navigation through all articles database.
In every website page you will find a special section (at the beginning or the end) with tags just like this and also different tags associated with the current article.
Tags inter-links stories with the similar content, so if you click on the tag you will find only related and relevant LED content.
LED Component Tester with Torch
Mar 6th
Here is a simple tester for Hobbyists. This LED Component tester can test the integrity of electronic components from resistors to ICs before soldering. It reduces the job of testing the components using multimeter. The tester gives LED indications about the Good or Bad conditions of the components. A White LED torch is added to verify the value of the components if light is not sufficient
Telephone Status Indicator
Mar 5th
This simple circuit tells you about the status of phone such as Line OK, Dialing and Call attended. It also has a lock facility to block outgoing calls keeping the incoming calls as usual. This prevents misuse of telephone. The circuit uses only a few components to do all these jobs
Aquarium Led Lighting
Mar 3rd
This colorful back led aquarium lights gives natural appearance to the Aquarium tank. The Aquarium Led Lighting circuit automatically turns on at sunset and gives changing White, Blue and Green color display to make the aquarium attractive. In the morning the aquarium led light turns off. (more…)
Organic LED. The exciting display device
Feb 23rd
Organic LED, the commonly called OLED is a solid state semiconductor light emitting diode having a thickness of 100 to 500 nanometers. It is also called as Organic Electro Luminescent Device (OELD) These devices are currently used in small screen displays such as mobile screen, digital camera etc. The OLED display is much thinner than LCD and consumes less power. Research in the field of OLED is progressing and many manufacturers are trying to make OLED displays in TV, computer monitor etc (more…)

This is the extension of the article Light Emitting Diode -How it works? Recent advances in solid state lighting techniques allow LEDs to generate light at levels that is similar to traditional lighting systems. Now high power LEDs are available which have the potential to replace the fluorescent lamps. Lattice LED is the new generation LED used in display boards and TV screens
Light Emitting Diode How it Works?
Feb 16th
LEDs form an inevitable part in the modern electronics as simple indicators to optical communication devices. Light Emitting Diodes exploit the property of the p-n junction to emit photons when it is forward biased. LEDs are specially made diodes to emit light when a potential is applied to its anode and cathode. (more…)
