Abstract

A networked light bulb is disclosed comprising means for controlling a state of the networked light bulb, means for connecting to a network, means for allowing a user to select a color from a plurality of colors, the plurality of colors having at least one locking color and one or more non-locking colors, and means for generating a selected color code corresponding to the color selected by the user, each color of the plurality of colors having a corresponding color code. If the user selects the locking color, the networked light bulb disconnects from the network and turns the light bulb on. If the user selects a non-locking color, the networked light bulb submits the selected color code over the network for use by the network controller in configuring the device and changes the state of the networked light bulb in response to a command from the network. In some embodiments the networked light bulb also responds to requests for status information from the network independent of the color selected by the user. In some embodiments that means for controlling the networked light bulb controls the brightness of the light.

Claims

1. A method for configuring a networked lighting apparatus comprising:

generating a selected color code corresponding to a color selected from a plurality of colors, the plurality of colors having at least one locking color and one or more non-locking colors and each color of the plurality of colors having a corresponding color code;

disabling a network connection if the color selected is the at least one locking color; and

only if the color selected is one of the one or more non-locking colors,

(a) connecting to the network,

(b) sending the selected color code over the network, and

(c) changing a state of the networked lighting apparatus in response to a message received over the network.

2. The method for configuring the networked lighting apparatus of claim 1 further comprising responding to a request for status information from the network only if the color selected is one of the one or more non-locking colors.

3. The method for configuring the networked lighting apparatus of claim 1 further comprising:

receiving a local control action;

changing the state of the networked lighting apparatus in response to the local control action only if the color selected is one of the one or more non-locking colors.

4. The method for configuring the networked lighting apparatus of claim 1 wherein the state of the networked lighting apparatus being changed is a brightness level of the networked lighting apparatus.

5. The method of configuring the networked lighting apparatus of claim 4 wherein the brightness level is limited to On and Off.

6. The method of configuring the networked lighting apparatus of claim 4 further comprising:

setting the brightness level of the networked lighting apparatus to at least 10% of maximum if the color selected is the at least one locking color.

7. A networked light bulb comprising:

a light emitting apparatus;

a controller;

a network adapter communicatively coupled to the controller; and

a color selection mechanism communicatively coupled to the controller, the color selection mechanism allowing a user to select a color from a plurality of colors, the plurality of colors having at least one locking color and one or more non-locking colors;

wherein

the color selection mechanism communicates information corresponding to the color selected by the user to the controller;

if the color selected by the user is the at least one locking color, the controller disables the network adapter; and

if the color selected by the user is one of the one or more non-locking colors,

(a) the controller converts the information communicated by the color selection mechanism to a color code corresponding to the color selected by the user,

(b) the controller communicates the color code to the network adapter,

(c) the network adapter sends the color code out over the network,

(d) the network adapter receives a message from the network to change a state of the networked light bulb and communicates it to the controller, and

(e) the controller changes the state of the networked light bulb in response to the message to change the state of the networked light bulb communicated by the network adapter.

8. The networked light bulb of claim 7 in which the network adapter connects to a wireless network selected from the group consisting of Wi-Fi, Z-wave and Zigbee.

9. The networked light bulb of claim 7 in which the controller and the network adapter are integrated on a single integrated circuit.

10. The networked light bulb of claim 7 in which

the network adapter receives a status request message from the network and communicates it to the controller only if the color selected by the user is one of the one or more non-locking colors;

and

the controller responds to the status request message communicated by the network adapter by communicating a response message to the network adapter to send out over the network.

11. The networked light bulb of claim 7 in which the state of the networked light bulb being changed is a brightness level of the light emitting apparatus.

12. The method of configuring the networked lighting apparatus of claim 11 wherein the brightness level is limited to On and Off.

13. The networked light bulb of claim 7, the color selection mechanism comprising:

a rotary switch with a rotatable shaft and an output communicatively coupled to the controller; and

a color wheel having a center, an edge and a colored area, the center of the color wheel coupled to the shaft of the rotary switch and the colored area divided into sections, each section imprinted with a section color selected from the plurality of colors;

such that

as the color wheel is rotated by user manipulation of the edge, the colored area of the color wheel and the rotatable shaft of the rotary switch also rotate; and

the output of the rotary switch communicates current rotational position information corresponding to the color selected by the user to the controller.

14. The networked light bulb of claim 13, the color selection mechanism further comprising:

a selection mark in close physical proximity to the section of the colored area of the color wheel imprinted with the section color corresponding to the color selected by the user at the current rotational position.

15. The networked light bulb of claim 13 further comprising an outer housing with an aperture;

wherein

the color wheel is mounted in the networked light bulb so that,

a portion of the edge of the color wheel protrudes from the outer housing of the networked light bulb, whereby the user is able to manipulate the edge to rotate the color wheel about its center;

a portion of the colored area is visible through the aperture in the outer housing of the networked light bulb; and

a majority of the portion of the colored area visible through the aperture in the outer housing of the networked light bulb is the section of the colored area imprinted with the section color corresponding to the color code selected by the user at the current rotational position.

16. The networked light bulb of claim 13 in which at least one section of the colored area is also imprinted with a visible symbol.

17. The networked light bulb of claim 13 in which at least one section of the colored area has a tactilely recognizable symbol.
