What is a superflux led?
Superflux LEDs are the pinnacle of LED lighting. At a glance at the specifications it would appear that they are not as bright as the 3mm and 5mm LEDs, however with their 110 degree viewing angles they kick out an enormous amount of light. Making them perfect for vehicle stop lights, signs and many many more applications. Superflux LEDs are also known as Piranha LEDs. http://www.phenoptix.co.uk/Superflux_LEDs_s/35.htm
Why do defective LEDs flash?
Defective leds flash due to the temperature of the chip. When the LED chip is hot, the filament disconnect(the LED light turn OFF) and when it came cold it connect again (the LED light turn ON). It is similar to the bimetallic switch, see: http://www.youtube.com/watch?v=j-JNyFn85rI Try to get a led witch have a better quality.
Different between led infrared led?
Both are light emitting diodes, but an infrared led emits infrared light in the electromagnetic spectrum. With the naked eye, humans can't see infrared light but many cameras can. Infrared leds are used in remote controls and many other applications.
Why is silicon not used in fabrication of LED?
Silicon is an indirect band gap semiconductor
How do you wire Bi-color LEDs?
Treat each color as a separate LED and wire accordingly. Be sure to observe the polarity of the component (anode and cathode +/-)
What are the benefits of using LED's?
SMD LEDs are also known as SMT LEDs, or Surface Mount Technology, and carries a major benefit over through-hole LED Lamps. SMT LEDs are suitable for reflow-soldering, so the manufacturing process for boards containing SMT LEDs can be accelerated and streamlined, saving time and money.

What color LEDs in Gallium used to make?
Gallium nitride (GaN) LEDs are commonly used to create blue LEDs. By combining a blue LED with a yellow phosphor coating or a green and red LED, white light can be produced. Additionally, different additives can be incorporated to create other colors such as red, green, and yellow LEDs.
Are leds dangerous?
led lamps are not dangerous
What are the LED's in Xbox360 called?
0603 LEDs
What type of LEDs used in Xbox360 called?
LED's
Are all LEDs dimmable?
No, not all LEDs are dimmable. Some LEDs are designed to be dimmable, while others are not. It is important to check the product specifications to see if an LED is dimmable before attempting to dim it.
Which screen is better to see led or LCD?
leds are good for producing bright vivid colours but lack the refresh rate of an lcd lcds are good for speed and picture quality but colours are not as vivid as leds this is all down to personal preference some people prefer lcds over leds or visa versa
What are the disadvantages of LED displays?
Here i am sharing some of the disadvantage of LED Displays are : LEDs are currently more expensive LED performance largely depends on correctly engineering LEDs must be supplied with the correct voltage and current LED's can shift color due to age and temperature.
How many led are there in a led screen?
If the question refers to an LED illuminated LCD television, there will be several hundred individual LEDs forming a single panel. A true LED television uses a separate LED for red, green, and blue dots at every pixel. A 1920 x 1080 pixel television has just over 2,000,000 pixels. Each one needs a red, a green and a blue LED so there will be a total of 6,220,800 LEDs making up the image.
What does the LED do in the curcuit?
The main function of an LED (Light Emitting Diode) is simply to show a "light." LEDs can be used singularly, as in a hand torch, or in groups, as in the lights used on vehicles, and illuminated signboards, etc. The advantage of LEDs over conventional filament bulbs is low power requirements, long life and robustness.
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.
