Phillips Ambilight technology is a curious thing, never quite catching on in the mainstream due to its proprietary nature. Consisting of an LED array that sits behind a television screen, it projects colours relevant to the content on screen to create a greater feeling of ambience. [Ed Chamberlain]’s reactive pixel lamps aim to do much the same thing in a more distributed way.
Each pixel lamp consists of a Wemos D1 controller fitted with an old-school 4-wire RGB LED. The components are placed in a 3D printed translucent cube, which serves as an attractive enclosure and diffuser. With WiFi connectivity on board, it’s possible to connect the individual cubes up to a Raspberry Pi serving as a Phillips Hue bridge thanks to DIYHue. Once setup, the lights can be configured as an Ambilight system within the Phillips Hue app.
It’s an impressive way to give a room reactive lighting on a budget, without resorting to costly off-the-shelf solutions. We’d love to see this expanded further, as we’re sure a room full of reactive lights would be truly a sight to behold. Other methods to recreate the Ambilight technology are possible, too.
