High Quality ABS Plastic Home Sensor LED Light with 23 LED BulbsLong life as compared to standard incandescent bulbs 
Low wattage; save energy, the environment, and also save money on electric bill

Features:1.Energy efficient;Long life
2.Health,UV light does not contain health and infrared light, does not produce radiation (ordinary light contains ultraviolet and infrared ray)
3.Environmental Protection:Mercury and xenon, and other harmful elements, conducive to recovery and, and will not produce electromagnetic interference (ordinary lamp contains mercury and lead elements of the electronic ballast energy saving lamps will produce electromagnetic interference)
4.Protect eyesight:DC drive, no flash (normal lights are AC drive, it will inevitably generate strobe)
5.Optical efficiency:Heat a small, 90% of the electricity into visible light (80% of ordinary incandescent electric energy into heat, only 20% of electrical energyinto light energy)
6.Safety factor:The required voltage, current is small, less heat, no security risks, in mines and other dangerous places
7.Low-voltage, DC power supply, battery, solar power, in remote mountainous areas and outdoor lighting and other power shortage, a small electric field.

INTRODUCTION
This e-book covers the Light Emitting Diode. 
The LED (Light Emitting Diode) is the modern-day equivalent to the light-globe.
It has changed from a dimly-glowing indicator to one that is too-bright to look at.
However it is entirely different to a "globe."
A globe is an electrical device consisting of a glowing wire while a LED is an electronic device.
A LED is more efficient, produces less heat and must be "driven" correctly to prevent it being damaged.
This eBook shows you how to connect a LED to a circuit plus a number of projects using LEDs.
It's simple to use a LED - once you know how.INSIDE A LED:

A "Natural" or "Characteristic" voltage develops across a LED when it is correctly connected in a circuit with a current-limiting resistor to allow a current of between 1mA and 20mA. This voltage is shown in the table above and we normally use the lower value for each colour. However the table shows the voltage varies quite a lot and this depends on the actual crystalline construction of the crystal and the way it is manufactured. You cannot change this and that's why you need to measure the voltage across the LED when building some of the circuits.  

CONNECTING A LED
A LED must be connected around the correct way in a circuit and it must have a resistor to limit the current.
The LED in the first diagram does not illuminate because a red LED requires 1.7v and the cell only supplies 1.5v. The LED in the second diagram is damaged because it requires 1.7v and the two cells supply 3v. A resistor is needed to limit the current to about 25mA and also the voltage to 1.7v, as shown in the third diagram.  The fourth diagram is the circuit for layout #3 showing the symbol for the LED, resistor and battery and how the three are connected. The LED in the fifth diagram does not work because it is around the wrong way.

220V AC Ultra Bright LEDs lamp Circuit

This ultra-bright white LED lamp works on 230V AC circuit with minimal power consumption. Ultra-bright LEDs available in the market cost Rs 8 to 15. These LEDs emit a 1000-6000mCd bright white light, like the welding arc and work on 3 volts, 10 mA. Their maximum voltage is 3.6 volts and the current is 25 mA. Anti-static precautions taken Pls Should Be handling the LEDs. The LEDs in a water-clear plastic package emit spotlight, while diffused type LEDs have a wide-angle radiation pattern.
