These pretty strips of light are plastic diffused backlights, often seen in LCD displays. Normally they're tucked behind the LCD and shine white light from below. Here, we've got the LEDs available individually and they're really cool! Each LED is encased in a 3.5mm thick strip of a acrylic. The acrylic strip is a special type that is very good at diffusing light, so even though there is only one single white LED, it provides near-uniform lighting. The other flat side of the strip has a reflector on it so you only get light from the top (otherwise the backlight would lose 1/2 the brightness unnecessarily).

You can treat this backlight just like an LED, light with ~3V at 20mA current and you get a pretty shape that you can mask with vinyl or draw over with marker. Gels can be used to change the color. We think these would make great wearables without the need for EL or inverters, they're much brighter than EL and use less battery. The trade-off is these are not flexible at all.

This particular backlight has a 45mm x 86mm lit area - weight is 17g

White LED Backlight Module

Essetially its one white LED embedded is a shaped slice of plastic used to illuininate forward. Its going on my 3D printer to light up the printed part. Works fine. just what i wanted. I suspect when fixed in I will add a 220 ohm resistor to limit the current.

Slide illumination?

I bought a couple of these with a view to using them as back illumination for copying transparencies. It’s not a criticism of the product but for my purposes I could do with a higher lumen output, warmer colour temperature and a more even illumination. Admittedly at a glance one wouldn’t notice the gradation in brightness. I wouldn’t hesitate to recommended these for less critical applications where a panel is required.
