Why germanium and silicon are not preferred in LEDs?
A: Because the element has different property as gallium arsenide.
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.
How does OLED work on TVs Is it is really possible to show images on a screen so thin.?
OLED stand for organic light emitting diode. Like conventional LEDs, each diode emits light. Put a red, green and blue LED together and they are able to create any color. Because the LEDs emit light, they do not require a separate back light component so the screen depth can be reduced significantly. LED screens have been used for many years in open air and arenas. The very compact form of organic LEDs offers opportunities to use LEDs in compact, domestic sized televisions. Because of the simpler construction, it is likely that LED television will become norm in just a few years from now.
Which company will be producing the largest OLED TV soon?
OLED is the latest display technology to be introduced to the domestic television market. It is impossible to predict the largest OLED television and indeed, a little pointless to look at size as a milestone in LED television technology. OLED allows LEDs to be printed onto a substrate at very small sales so it is ideal for small screens. As the screen size increases, conventional LEDs become more viable than OLED. The largest true LED driven screens are those seen in open air and concerts, up to 40 feet wide or more. At present, commercial factors will decide the largest OLED display to be marketed. Those people who are looking for huge screens still have an option to consider conventional LED displays. Note that LED displays referred to here means the displays that use LEDs to generate the image and not as back lights for LCD displays.
Are Fluorescent and LED lights the same thing?
NO. Fluorescent lights and LEDs are NOT the same thing, other than the fact that they both produce light. A fluorescent light consists of a glass tube or envelope with a powder [phosphor] coating on the inside of the glass which when "excited" by electrical energy created by current running through a gas, also inside the envelope, releases some of that energy in the form of light. An LED on the other hand is a solid state device with no tube, phosphors, or gas. It also converts electrical energy to light but by the interaction of two dissimilar electrically conductive compounds inside of a transparent or translucent plastic body.
What lights up on a Christmas tree?
Usually, strings of Christmas lights light up a Christmas Tree. Nowadays, the lights are more likely to be LEDs.
What differences are there between c9 and c7 Christmas lights?
The difference between c9 and c7 Christmas lights is their bulb size. They also use different amounts of energy. They both can be retrofitted for LEDs.
Where will you see LEDS in the streets?
Really there is no LEDs on the streets. The only place you can find them are in some cars and they are usually on the tail lights and not the head lights.
Make a list of the uses for leds?
LEDs are used in traffic lights, on computer lights, car lights and indicators. You can also purchase LED flashlights and torches. Can be used in small devices for a variety of uses.
Can you use a halogen light for a grow light?
You can, but it's not a great idea. Halogen lights, as with incandescent lights, use lots of electricity, and most of this generates heat rather than light.I would suggest using fluorescent, HID or LEDs for grow lighting.
Why would you choose LED grow lights instead of other grow lamps?
LEDs can be customized to emit only the light the plant uses for photosynthesis making it is a very efficient grow light. They also use very little electricity, create very little heat, and have a longer lifespan then other types of grow lights.
What lights were used in car headlights before LEDs?
Halogen Bulbs
Why do green leds on modern stop lights fail before leds of other colors?
Maybe it's used more? I don't Know.
Are LED grow lights very effective in growing plants?
Christmas Lights work and are really cheap!!! But seriously, as a horticultural lighting experts.....our experience with led grow lighting has been extensive, with many companies tested. To date the best led grow light we have tested are from ledgrowlightsexpert.com The growth we experienced in both vegetative and flowering stages of many different plant types was excellent. From wheatgrass to bromiliads...orchids to vegetables we saw explosive growth under the leds. Flowering and fruiting showed thick lush flowers and abundant fruit yielding
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
What components are in LED rope lights?
A: ROPE lights are not LEDS but rather incandescence bulbs using 16 Watts per foot
What kind of lights are in brake lights and turn signals?
They used to be incandescent, but more and more often now manufacturers are using LEDs.
