LED - light emitting diode Abbreviation of light emitting diode, an electronic device that lights up when electricity is passed through it. LEDs are usually red. They are good for displaying images because they can be relatively small, and they do not burn out. However, they require more power than LCDs.

LED lamp LED drivers are the essential components of LED lamps or luminaries. A good LED driver can guarantee a long life for an LED system and provide additional features such as dimming and control. The LED drivers can be put inside lamp or luminaire, which is called a built-in type, or be put outside, which is called an independent type. According to different applications, different types of LED drivers need to be applied, for example an outdoor driver for street light, an indoor point driver for a down light, and an indoor linear driver for a panel light.

FAQ - 12V Transformers and LED Compatibility Magnetic transformers will generally work with all MR16 LED lights, albeit at the cost of efficiency and extra power consumption as was explored in this FAQ article. 'LED drivers' are electronic DC power regulators designed specifically for DC LED lighting.R16 LED lights vary in complexity across manufacturers and model designs. The most basic 12V retrofit LED downlight will include the DC LED chips for the light source, and a bridge rectifier composed of diodes to deliver DC to the LEDs from the AC transformer supply.

Constant Current LED Drivers Constant Current LED Drivers. Delivering a fixed amount of current (often 350mA, 700mA or 1A) to your LED lights, a constant current driver allows your voltage to vary. The voltage requirements of your LED lighting system should fall within the minimum and maximum voltage range that each constant current LED driver specifies.

Are LED Light Bulbs a Fire Risk? Find LED lights >. The technology that drives LEDs (light emitting diodes) is called solid state lighting or SSL. This means light is not emitted from a vacuum (as is the case with incandescent lights) or from a gas (like CFL lights), but from something solid— a semiconductor.

What is the purpose of a led? An LED (light emitting diode) is used in electronic circuits to provide light where needed. Essentially, it is a low power lightbulb, which uses a gallium nitride/ indium phosphide P-N junctions to create light. They can be used in circuits to indicate that power is being supplied (the small light on your PC's motherboard).

Controlling LED lighting systems: introducing the LED driver An LED driver is the power supply for an LED system, much like a ballast is to a fluorescent or HID lighting system, says Al Marble, manager-sales & market development for Philips-Advance Transformer.LED drivers may be constant voltage types (usually 10V, 12V and 24V) or constant current types (350mA, 700mA and 1A).Some drivers are manufactured to operate specific LED devices or arrays, while others can operate most commonly available LEDs.he driver converts 120V (or other voltage) 60Hz AC power to low-voltage DC power required by the LEDs, and protects the LEDs from line-voltage fluctuations. Sodhi also believes that one of the most important LED driver features to examine is the quality of the DC output voltage of the driver.

Learn About LED Lighting LEDs are “directional” light sources, which means they emit light in a specific direction, unlike incandescent and compact fluorescent bulbs, which emit light and heat in all directions. For this reason, LED lighting is able to use light and energy more efficiently in many applications. However, it also means that sophisticated engineering is needed to produce an LED light bulb that shines light all around like an incandescent A-shape bulb.

Device Driver A device driver is a particular form of software application that is designed to enable interaction with hardware devices. Without the required device driver, the corresponding hardware device fails to work. A device driver usually communicates with the hardware by means of the communications subsystem or computer bus to which the hardware is connected. Device drivers are operating system-specific and hardware-dependent.
