User input systems for an LED-based light
First Claim
1. A fluorescent tube replacement device for use in a conventional fluorescent tube fixture, comprising:
- a housing comprising;
an opaque portion extending between opposing ends of the housing, anda transparent or translucent portion extending between the opposing ends of the housing;
a first end cap and a second end cap disposed on respective ones of the opposing ends of the housing, wherein the first and second end caps are configured to physically engage the device with one or more sockets of the conventional fluorescent tube fixture;
a plurality of LEDs disposed within the housing and oriented to emit light towards the transparent or translucent portion of the housing;
an LED controller disposed within the housing and configured to operate the LEDs according to a plurality of different operating states, the different operating states including a plurality of discrete ON states; and
a user input interface in communication with the LED controller, the user input interface configured to receive user input, and in response to the user input, activate the LED controller to operate the LEDs according to the different operating states, wherein the user input interface comprises a switch mounted to an exterior of the opaque portion and accessible to a user when the device is engaged with the one or more sockets of the conventional fluorescent tube fixture.

Abstract
An LED-based replacement light includes a plurality of LEDs, an LED controller for operating the LEDs, a user input interface in communication with the LED controller, a housing for the LEDs, the LED controller and the user input interface, and a connector disposed at an end of the housing and shaped for connection with a light socket. The LED controller establishes different operating states for the LEDs that include only a limited number of discrete ON states. The user input interface is configured to receive user input, and in response to the user input, activate the LED controller to operate the LEDs according to one of the different operating states.
