LEDs (light Emitting Diodes) generate visible illumination when an electric current flows through them converting electrical energy into light energy and less into heat energy. Making them more efficient than incandescent bulbs. The brightness of LED lights will depend on the ranges of power strength emitted from the diodes or twin terminal structures located on the insides. We supply them as through hole or surface mount (SMD) types like the popular **ChipLED**, there are different versions such as the **TopLED**, **SideLED**, **SmartLED**, **PointLED** and **Firefly** series.

**What are LEDs used for?**

Light emitting diodes are semiconductor devices, these electronic components can be used in a wide range of products and environments. From indicator lamps, signs, and displays including backlighting and seven-segment displays to consumer electronics such as calculators, digital watches, and smart devices. They can be used in remote-control circuits and can also replace small incandescent bulbs. Offering a long life, more energy efficiency and they are more economical. Other areas using this type of LED lighting include the automotive industry, aviation, our homes and businesses, street lighting, communication technologies and medical devices.

Generally, white LED lights are suitable for room and outdoor area lighting, Deep blue LEDs can be often used in horticultural environments. We have a broad range of visible and high brightness LEDs in all colours as well as RGB LEDs. All from leading manufacturers for example RS Pro, ams Osram, Broadcom, Cree LED, Kingbright, Lite-On, Lumileds, Nichia, ROHM, Vishay and Wurth Elektronik.

LEDs that are also available are the ultraviolet [UV LEDs](https://uk.rs-online.com/web/c/displays-optoelectronics/leds-light-emitting-diodes/uv-leds/) and infrared range [IR LEDs](https://uk.rs-online.com/web/c/displays-optoelectronics/leds-light-emitting-diodes/ir-leds/)

**LEDs have different visible lighting features**

- Flashing LEDs are attention seeking or warning indicators operated by multivibrator circuits, which flash at pre-set intervals. See our [Panel Mount - Flashing LEDs](https://uk.rs-online.com/web/c/displays-optoelectronics/indicators-indicator-components/panel-mount-indicators/?searchTerm=flashing%20leds)
- Bi-colour LEDs have two different coloured LED emitters in one unit to show system status, for example 'on' or 'off’
- Tri-colour LEDs have three LED emitters in one unit producing different colours, for instance the traffic light systems

The RGB LED (red, green, blue) have built-in control units to produce combinations of the primary colours and can often be seen in decorative and entertainment applications.



LEDs, Light Emitting Diodes convert electrical energy directly into light energy when voltage is applied. Making them an energy-efficient electronic component.

SMD LEDs | RS

SMD LEDs or surface mount device LEDs are used in surface mount technology (SMT) applications. Surface mounting involves mounting the LED on the surface of a printed circuit board (PCB) rather than through holes in the PCB (through hole mounting). SMD LEDs are available in many form factors or package types which indicate their dimensions. The advantages of SMD LEDs are that they are low profile, compact and occupy less space on the PCB than a through hole version. SMD LEDs can be mounted automatically using special pick-and-place equipment allowing cost effective production and they also have an enhanced heat dissipation capability resulting in increased reliability.

Blue LEDs | RS

A blue LED (Light-Emitting Diode) emits light in the blue portion of the electromagnetic spectrum with a typical wavelength of between 450 to 470 nanometers. Blue LEDs are used in the creation of white LED lighting which is achieved by adding a layer of phosphor material onto the blue LED which absorbs a portion of the blue light and emits light in other colours including yellow. This process creates white light and is known as phosphor conversion. The composition of the phosphor layer can be adjusted to produce different colour temperatures of white light. Blue LEDs are used in LED backlit LCD screens, OLED displays, signage and advertising, medical and scientific applications such as fluorescence microscopy as well as for simple decorative effect in accent and architectural lighting.

Buy RGB LEDs. Browse our latest RGB LEDs offers. Free Next Day Delivery.

RGB LEDs | RS

RGB LEDs emit light in three primary colours: Red, Green and Blue. The intensity of each colour in an RGB LED is controlled independently by multiple LED chips meaning different colours can be achieved. These colours include the secondary colours of yellow, cyan and magenta as well as a whole spectrum of other hues making these LEDs extremely versatile. RGB LEDs have many uses including decorative and ambient lighting in the office and home, theatre and concert lighting, automotive lighting and for eye catching displays and signage.
