Color changing backlight for fluid delivery devices displaying temperature

摘要

A display unit for a fluid delivery device which outputs water includes a printed circuit board, a diffuser supported by the printed circuit board, and a display screen electrically coupled to the printed circuit board. The display unit further includes a first light source electrically coupled to the printed circuit board, and a second light source electrically coupled to the printed circuit board. The first and second light sources define backlighting for the display screen. Operation of the first and second light sources is adjusted in response to a change in temperature of the output water of the fluid delivery device.

主权项

1. A fluid delivery device configured to output water comprising:
a temperature sensor for detecting temperature of the output water; a controller electrically coupled to the temperature sensor; a display unit electrically coupled to the controller and including a first light source configured to be operated by the controller to adjust backlighting of the display unit, the controller being configured to receive a signal from the temperature sensor and send at least one signal to the first light source in response to the signal from the temperature sensor; and a second light source configured to be operated by the controller to adjust the backlighting of the display unit, and the controller is configured to receive the signal from the temperature sensor and send at least one signal to at least one of the first and second light sources in response to the signal from the temperature sensor; wherein the controller causes the first light source to generate light of a first color when the signal from the temperature sensor detects a first water temperature, the second light source to generate light of a second color when the signal from the temperature sensor detects a second water temperature greater than the first water temperature, and the first and second light sources to blend the light of the first color and the light of the second color and generate light of a third color when the signal from the temperature sensor detects a third water temperature between the first water temperature and the second water temperature.
