Purpose
The purpose of an LED light bulb is to have a source of electric light. LED light bulbs also have the ability to give off a directional light; therefore the light goes where you aim it. They can also be used to replace the standard fluorescent or halogen light bulbs. LED light bulbs last around 130 times longer than Incandescent, plus they consume less energy and do not get heated up as traditional bulbs, making them easy to maintain. So overall the purpose of an LED light bulb is to have a source of light that lasts long, consumes less energy than standard light bulbs, and is easy to maintain. ([|source])

Energy
Most light bulbs use electricity that is converted to heat to then produce light, it’s no different with LED light bulbs. The difference is that LED light bulb don’t use filaments to produce light, and since the filament can’t burn out(because there isn’t one) the light lasts longer. Instead LED lights are lit when an electric current is passed through the positive and negative materials and energy that turns into heat and is released in the form of light.

Controls
There are some special Led light bulbs that you can purchase that have night automatic sensors. For example if you had a LED nightlight it would automatically turn on once the room was dark enough. You can also control the light by hooking up a light switch, so when you turn on the switch the electricity has a complete circuit, so the light so it can turn on. (Some also have a resistor built in.)

Materials
One of the main differences between standard lights and LED lights is that LED lights have two wires that electricity jumps across producing light. To get the electrical connection between the light sources and the wires there are a lot of complicated connection elements. The wire must be cut and soldered to conductive plates, then the bulb head is installed so that the wires of the light bulb can contact and form electrical connections with the conductive plates inside the bulb. Some of the wires are put into a boron oxide solution before being put into the light bulb. To keep them from escaping into the pressurized gas in the chamber, they are often covered with a layer of liquid which is Baron Oxide. ([|source])

Science
The main scientific principals in an LED light bulb are that the electric current can only pass through the light bulb if there is a complete circuit. Also there must be negative and positive materials for the light bulb to light up. Another principal is how the light reacts when passing through different mediums such as plastic compared to glass.

Evolution
In later years the LED light bulb could be changed so it has more reusable sources. As with all light bulbs scientists may find a way to make the bulb brighter, and with different materials they may last longer than they already do. Yet if scientists can do all this they will probably make it an entirely new light bulb.

Competitors
All other light bulbs are competitors for the LED light bulb (inside or outside.) An example of a competitor light bulb would be the Incandescent light bulb.

Partners
Any device that a light bulb can be plugged into work in conjunction with an average LED light bulb. For example a ceiling fan or a lamp would work in conjunction with this device.

Siblings
An incandescent light bulb does use some of the same scientific principles that a LED light bulb uses. For example it takes heat to form electricity. Yet no other light bulbs have a gap in-between to wires so electrons jump the gap and complete a circuit.
