LED Module

Have you ever wondered how LED Signs work, but could not understand all the technical jargon that most companies led such use to describe them? Do not worry! This is really not as difficult as you think. Basically, LED panels are only a few major components in their systems running and once we understand to be an expert enough to feel comfortable in your purchase took staff.

The LEDs are actually only bulbs that can easily tiny integrate into an electrical circuit. They are specially designed to send out a large number of photons.

And while they are housed in a plastic bottle that concentrates light in a certain direction, unlike ordinary bulbs, LED lights have no filament that burns exceptionally hot. They are fully illuminated by the movement of electrons in a semiconductor material, and the ability to take same time as any standard transistor.

The signal is a display screen LED integrated system, which combines microelectronic technology, photonic technology, computer technology, technology of information processing. It is also the type of screen used to display text, graphics, photographs, cartoons, videos and other information, controlled by the some control.

These are the three basic components of an LED sign:

1) MODULE LED

The modules are composed of LED, PCB, IC, resistors, capacitors, connectors, covers and other components of special modules have technical matrix 8 × 8, 8 × 16 16 × 16 16 × 32 and so on, and the corresponding pixels are 64/128/256/512. Pixel pitch is the distance between two adjacent pixels from the central point, as PH4.75, PH6, PH10, PH16, PH20, and so on.

2) The Cabinet

Switching modules, power supplies, fans and other components mounted in the cabinet. Cabinets have spec. 4:3, 16:9, etc. They can be customized according to requirements of customers, and can also be produced by the standard specification. The box is produced by the simplicity of maintaining and improving the reliability of

3) LED DISPLAY

The LED screen is mounted cabinets or modules, receiving letters (AC), power supply, and part of the screen, communication cable and other components so that now you should have a basic idea of how the work carried signs and details in general must have been before. However, if you do not understand the process that leads, visit our website and review the table carefully designed to help visualize the technique.

Question about semiconductor LED?

A blue LED semiconductor connected in series with a resistance of 10 Ω series to a voltage source. The LED emits 4.03 x 10 ^ 16 photons / s at a wavelength of 400 nm. The current flowing through the LED is 40 mA and the voltage across the LED is 3.5 V. What would the energy conversion efficiency of the diode. TKS a lot for your help!

The energy of a photon, E, E = hc / l, c = 2.998 × 108 m / s = speed of light = 6.626 × 10-34 joules · s L = Planck's constant = wavelength of EE total energy emitted is then 4.03 * 10 ^ 16 * E conversion efficiency energy = EE / (3.5 * 0.04) Please put in numbers. http://pvcdrom.pveducation.org/APPEND/Constant.htm http://pvcdrom.pveducation.org/SUNLIGHT/PENERGY.HTM.
