LED, which stands for Light Emitting Diode, generate light using a semiconductor material. As the voltage is applied to the semiconductor, the energy that is used by the LED is converted into light energy.
Different semiconductors produce different types of light. Red and green were discovered first, followed by yellow, orange, blue and finally white.
This is usually Green and No chemicals , dont care, dont know

Is it legal to operate LED lights in Nevada?
LED lights are legal in Nevada as long as they light up using the correct color while operating.
In Texas is it legal to operate a motorcycle that is equipped with colored neon lights or LED's?
No, in fact it's a moving violation.
Cut Office Costs With LED Lights?
Offices can improve their energy efficiency by opting to use LED lights. An LED light is extremely bright, but is much smaller than the standard halogen bulb. LED lights require very little electrical power to operate.
Can T8 LED tube light be used with ballast and can ballast be removed and will it work?
A T8 LED tube has to be used with a ballast to bring the correct voltage to the tube for it to operate correctly. Removing the ballast from the circuit will prevent the tube from operating.
Is it legal in Arizona to operate a motorcycle with LED accent lights?
Not the cool ones. Colors are limited. White/Amber visible from the front. Red from the back.
The northern colonies' focus on small-farm agriculture and the manufacturing of goods as opposed to the large southern plantation system led to what?
It led to the acceptance of slavery as a legitimate economic method to operate the Souths large farms and plantations. Bad idea!
What is the minimum voltage necessary to operate a light emitting diode?
That will vary with the type (i.e. "color") of the LED: IR LEDs operate at the lowest voltage (1.2V), red LEDs operate at low voltages (1.8V), green LEDs operate at medium voltages (2.5V), blue LEDs operate at high voltages (3.3V), and UV LEDs operate at the highest voltages (4V). Intermediate color LEDs operate at correspondingly intermediate voltage between those given above. The reason an LED cannot produce light below these voltages is it takes more voltage drop to get the energy to produce higher energy photons and the different types of binary semiconductors needed to produce each color/energy of photon result in different junction forward bias voltages.However LEDs are really current operated devices, not voltage operated devices, so they need a series resistor or a current source to limit the current through them. Simply applying a voltage source with the necessary "minimum operating voltage" across an LED will generally destroy it instead of lighting it.
What is frequency of IR LED of TV remote?
Most infra-red remote controls operate in the region of 36KHz - 40KHz although some are in the 50Hz region or higher.
How does an LED light not light up when a positive wire is on a negative terminal and negative wire on positive terminal?
Because LED means light-emitting diode and the clue is in the diode, because diodes are 'polarised', which means that the current must flow in the correct direction for them to operate correctly.
What is the future tense of operate?
The future tense of "operate" is "will operate"
What voltage is needed to operate a 30 watt and 40 watt LED lights?
Some LED lights are manufactured to run on low-voltage, usually 12 v, while others are manufactured to run on the local supply voltage, usually 110/120 v or 230/240 v.
Why does alarm light blink on caliber when no alarm on vehicle?
There are two possibilities: There is an integrated alarm that you operate just buy having the correct key or Someone has fitted a fake alarm led. (light)
