Abstract
Various arrangements for light distribution incorporated as part of a device are presented. A circular light guide may be used that receives light from a plurality of light emitters that can be arranged in a circular pattern. A conical reflector may be used and may be positioned to reflect light emitted from the circular light guide onto an exterior of a case of the device. The conical reflector may reflect light such that light is reflected by the exterior of the case in the shape of a halo into an ambient environment of the device.
Claims21
(canceled)
A combination carbon monoxide and smoke detector, comprising:
- a case;
- a carbon monoxide sensor housed within the case;
- a smoke sensor housed within the case;
- a plurality of light emitters arranged in a pattern and mounted within the case;
- a light guide that is formed from a translucent or transparent material and that receives light from the plurality of light emitters and emits light through a first surface of the light guide;
- a button, wherein the light guide causes light to be emitted around an edge of the button;
- blackout material arranged against a second surface of the light guide;
- one or more processors housed within the case, wherein:
- the one or more processors are in communication with the carbon monoxide sensor, the smoke sensor, and the plurality of light emitters;
- and
- the one or more processors are configured to activate the plurality of light emitters such that light is emitted into an ambient environment in a shaped pattern.
