How many types of light bulbs are there?
352 There are six different types of light bulbs invented as of December 27, 2012. They include the incandescent light bulb, the halogen light bulb, the fluorescent light bulb, the high-density discharge lamps, LEDs, and sodium lamps.
Where LEDs commonly used today?
In torches,
What are the different types of integrated science?
different types bioligy,chemistry&physic
What are the different types of ISAR System- Explain?
the different types of ISAR System
Give you a list of different types of opposites?
give me different types of opposites means i am asking that i need some different types or kinds of opposites
How are LEDs different from other artificial light sources?
The difference is that LEDs use less electricity.
What types of products does Thine Electronics sell?
Thine Electronics sell parts used to produce chips, such as LED drives, LEDs, multiple different types of recievers and transmitters, and chips to put into your motherboards.
What makes up the lights of a set of traffic lights?
Incandescent light bulbs are used, in addition to LEDs. LEDs or laser emitted diodes, produce the different colours with different electricity molecules mixing with the oxygen in the air
Which is a more powerful light - 95 leds or 128 leds?
If your compairing apples to apples like 3 watt leds to 3w leds then 128. The more leds the higher the power.
What Are Two Types Of LED Display?
conventional (using discrete LEDs) and surface-mounted device (SMD) panels.
How much energy does a led use per hour?
LEDs come for different power ratings. Miniature LEDs use between approximately 40-90 mW. High-power LEDs - used for illumination - can use hundreds of watts per square centimeter.
Why germanium and silicon are not preferred in LEDs?
A: Because the element has different property as gallium arsenide.
When to connect LEDs in parallel?
Basically, when LEDs are connected in parallel, the LEDs with the lowest resistance will be the brightest, the other LEDs will be dimly lit or not lit at all. Therefore, use LEDs with the same model number and colour.

What is wavelength of led?
The wavelength of light emitted by LEDs typically ranges from about 400 to 700 nanometers, depending on the material used in the LED. Different colors of LEDs are produced by varying the chemical composition of the semiconductor material.
Which energy changes light energy into electrical energy?
Different light bulbs, lamps, flashlights, LEDs.
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.
