An Apple patent filed back in May and published today describes how an iDevice backlight could serve as a strobe light. Apple gives a couple of examples of how this might be used …

The first is to effectively act as personal disco lighting, though it is written in the usual dense patent language.

A second use, backed by an illustration, would be to act as a safety strobe for joggers.

Amusingly, for a patent filed this year, one of the drawings is of an iPod Classic – a fact which makes more sense when Apple notes that it’s a continuation of a series of patents dating back to 2004. The text does, however, say that the device may be a media player, a phone or both.

As with all Apple patents, there’s no telling whether the idea might actually make it into a product.
