This diffused acrylic backlight strip gives you an easy way to add a smooth, colourful glow to projects. It is the kind of light guide normally found behind LCD panels, but this version uses a single RGB LED so you can drive red, green and blue channels independently.

The LED is encased in a 3.3mm thick acrylic strip that spreads the light for near-uniform illumination. A reflector on the flat rear side directs the light out through the top, helping avoid wasted brightness.

You can wire it much like a common-anode RGB LED: connect the longest pin to 3~5VDC, then connect the shorter red, green and blue pins through current-limiting resistors to ground. The lit surface can be masked with vinyl or drawn on with a marker for custom shapes and effects.

It is a neat option for wearables and compact lighting effects where you want something brighter than EL without needing an inverter, though the strip itself is not flexible.

Specifications:

Acrylic strip thickness: 3.3mm
Anode pin: Longest pin
Operating voltage: 3~5VDC
Channel current: Each should draw no more than 20mA
Lit area: 0.4" by 1.5" (12mm x 38.7mm)

Jargon buster

Plain-language definitions for the technical terms used above.

common-anode: A wiring arrangement where several LEDs or LED segments share a common positive (anode) terminal and are switched individually on their negative (cathode) side. Common-anode and common-cathode parts, such as RGB LEDs, seven-segment displays, matrices and strips, are not interchangeable without a suitable driver.
LCD: LCD stands for liquid crystal display, a screen technology that uses a backlight and liquid crystals to show images or text. It matters because LCD modules usually need a display driver and enough controller pins or a bus interface to send image data.
LED: A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
RGB: Short for red, green and blue, the three primary colours of light that are mixed in varying amounts to make a wide range of colours. In electronics RGB can refer to an LED or pixel that blends these three colours, or to a colour signal or interface that carries separate red, green and blue channels.
