Abstract
The present disclosure describes key lighting assemblies, electronic devices and keycaps. In one aspect, a key lighting assembly comprises a keycap defining at least one key. The keycap has one or more decorations. The assembly comprises a keycap, defining a key. The keycap has a non-opaque portion to identify the key. The assembly further comprises a light guide which is mounted in spaced relation with the keycap and an optical radiation source optically coupled to the light guide. The assembly further comprises a first opaque layer disposed on a first surface of the light guide. The first opaque layer defines a first opaque layer opening for passing optical radiation from the light guide to the keycap. The first opaque layer opening is located to permit optical radiation to be transmitted from the light guide to the non-opaque portion.
