Abstract
A light ring assembly for a bathroom fixture. The light ring may illuminate one or more light sources in a predetermined sequence and/or in an overlapping manner to create a pulse of light that traverses the circumference of the light ring. Different patterns, colors, and/or sequences of light may be used to convey messages and signals to owners, maintenance, and/or users.
Claims20
A system comprising:
- a sensor configured to detect an object in proximity to a sensor;
- and
- a light ring assembly comprising:
- a circuit board comprising:
- a plurality of light emitting diodes (LEDs) arranged on the circuit board;
- and
- a controller configured to illuminate one or more of the plurality of LEDs;
- and
- a memory configured to store instructions for illuminating the plurality of LEDs, wherein the instructions are configured to illuminate the plurality of LEDs to convey one or more messages;
- and
- a light pipe connected to a peripheral edge of the circuit board.
8 more elements
A method comprising:
- detecting, using one or more sensors, an object in proximity to the one or more sensors;
- based on the detecting the object in proximity to the one or more sensors, illuminating a first light emitting diode (LED) to produce a first instance of a pulse of light;
- illuminating, based on the first LED reaching a defined brightness, a second LED to produce a second instance of the pulse of light, wherein the second LED is gradually illuminated in an overlapping manner with the first LED;
- decaying the illumination of the first LED in response to illuminating the second LED;
- illuminating, based on the second LED reaching the defined brightness, a third LED to produce a third instance of the pulse of light, wherein the third LED is gradually illuminated in an overlapping manner with the second LED;
- and
- decaying the illumination of the second LED in response to illuminating the third LED, wherein the first instance, the second instance, and the third instance cause the pulse of light to smoothly traverse an exterior surface of a plumbing fixture.
