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;
- a light ring assembly comprising:
- an annular circuit board comprising:
- at least one light emitting diode (LED) driver circuit;
- a plurality of LEDs arranged on the annular circuit board equidistant from each other;
- and
- a controller configured to illuminate, via the at least one LED driver circuit, one or more of the plurality of LEDs based on the sensor detecting the object in proximity to the sensor;
- a light pipe connected to a circumference of the annular circuit board, wherein the light pipe is configured to:
- bend the light produced by the plurality of LEDs for delivery to an edge of the light pipe;
- and
- diffuse light produced by the plurality of LEDs.
8 more elements
A method for generating a pulse of light comprising:
- illuminating a first light emitting diode (LED);
- illuminating a second LED based on the first LED reaching a defined brightness, 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 a third LED based on the second LED reaching the defined brightness, 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.
3 more elements
