what is an addressable led?

As a digital LED strip, each addressable LED has an integrated driver that allows the brightness and color of each LED to be controlled individually, that is, an LED can be a different color to the one next to it. Thus, it enables us to create beautiful and complex lighting effects.

4K (UHD or Ultra High Definition) refers to the number of horizontal display pixels on the screen (4096 by 2160 pixels). LED stands for light-emitting diode and is oldest and least expensive HDTV technology. LED-based LCD TVs use “light-emitting diodes” behind the liquid crystals.

MetroCluster (FCVI) adapter LEDs. MetroCluster adapters have LEDs that you can check to learn whether the adapter has power and whether an error has occurred. MetroCluster adapters are also known as Fibre Channel Virtual Interface (FCVI) adapters.

NOTIFIER's intelligent addressable control module provides supervised monitoring of wiring to load devices that require an external power supply to operate, such as horns, strobes, or bells. It is capable of Class A and Class B supervision.

Not all LED's are dimmable. The box should say if they are dimmable. Usually if they are dimmable, the instructions might say something like dimmable with standard dimmers.

LEDs come in all sorts of sizes as well. Here is a photo showing a 3mm, 5mm and 10mm LED. the "millimeter" size refers to the diameter of the LED. For example, if you need to drill a hole in a box for your 5mm blinky LED, the hole size should be 5mm, and you'd need a 5mm drill bit to make it.

Functional addressing is an addressing scheme that labels messages based upon their operation code or content. Physical addressing is an addressing scheme that labels messages based upon the physical address location of their source and/or destination(s).

An indicator is a light or LED that prompts the user to the status of a hardware device. Examples of indicators include the indicators for when the hard drive is working (reading/writing) and when the caps lock is enabled. The picture shows the three indicator LEDs on the keyboard.

Miniature indicator LEDs are normally driven from low voltage DC via a current-limiting resistor. Currents of 2 mA, 10 mA and 20 mA are common. Sub-mA indicators may be made by driving ultrabright LEDs at very low current. Efficiency tends to reduce at low currents, but indicators running on 100 μA are still practical.

Most LED drivers are designed to provide constant currents to operate the array of LEDs. Consequently, the LEDs that count on a driving circuit to continuously operate at a constant current level are known as DC LEDs. However, an alternating current (AC) source may be employed to drive the LED lighting system.

LEDs are ideal as they are brighter but do not produce the same glare that HIDs are responsible for. LEDs are compact and energy efficient. Unlike the HID, LED headlights provide instant light when turned on.

DLP (Digital Light Processing) Link is a communication protocol that uses the DLP® chip inside DLP TVs and projectors. The DLP chip sends an embedded light signal to the 3D glasses between each video frame that synchronizes the 3D image with the glasses. These glasses do not require an emitter.

DEFORMABLE LAMP- can illuminate the range 360. The three aluminum LED heads are adjustable. They are can be folded up to 90, the light is equipped with a microwave motion sensor that quickly responds to movement from people, cars garage doors etc., and turned off in 15s, You can adjust the lighting range at will.

An optical mouse is a computer mouse which uses a light source, typically a light-emitting diode (LED), and a light detector, such as an array of photodiodes, to detect movement relative to a surface.

Byte addressable means that every byte has its own unique address and can be accessed. Word addressable means that every word has its own unique address and can be accessed.

LED (light-emitting diode) is a type of bulb that produces light using a narrow band of wavelengths. LED lighting is more energy efficient than CFL bulbs, as well as all other types of fluorescent lighting. LED bulbs produce a unique color of light that is very similar to the natural light of the sun.

You'll see dots on the map that show the devices current location. The color indicates how recent it was active and whether or not it is the current device.
