The technology also involves the illumination module emitting a coded pattern when operating in a second mode. This can be done concurrently so that the person cannot perceive the coded pattern. This can involve coordinating a light emitting diode (LED) on/off frequency of the illumination module, along with an image sensor capture rate and exposure time. The coded pattern may be used to complement the information displayed to the person, aid in autonomous operation of a vehicle, identify environmental or other conditions to a computing device, or provide other technical benefits. ## Claims ### Claim 1 An illumination module, comprising: a set of light emitting diodes (LEDs) configured to provide illumination; and a controller operatively coupled to the set of LEDs, the controller being configured to cause the set of LEDs to operate in multiple phases that concurrently (1) provide a coded pattern detectable by an image sensor, and (2) provide illumination perceivable by a person, wherein the coded pattern is not perceivable by the person. ### Claim 2 (depends on 1) The illumination module of claim 1, wherein the coded pattern comprises one of a barcode, a binary code, or a QR code. ### Claim 3 (depends on 1) The illumination module of claim 1, wherein the controller is configured to cause the LEDs to operate in the multiple phases according to a selected duty cycle. ### Claim 4 (depends on 3) The illumination module of claim 3, wherein the duty cycle is a 50/50 duty cycle. ### Claim 5 (depends on 1) The illumination module of claim 1, wherein the coded pattern is selected to complement user information provided by the set of LEDs that is perceivable by the person. ### Claim 6 (depends on 1) The illumination module of claim 1, wherein: the image sensor is part of a client computing device; and the coded pattern includes information that is presentable to the person via the client computing device. ### Claim 7 (depends on 6) The illumination module of claim 6, wherein the information that is presentable to the person includes information associated with a business. ### Claim 8 (depends on 1) The illumination module of claim 1, wherein: the image sensor is part of an industrial system; and the coded pattern includes information usable by the industrial system to control or modify operation of the industrial system. ### Claim 9 (depends on 1) The illumination module of claim 1, wherein the illumination module is part of a vehicle, and the set of LEDs comprises one or more of a brake light, a turn signal, headlight or a daytime running light. ### Claim 10 (depends on 9) The illumination module of claim 9, wherein the coded pattern is configured to provide information regarding operation of the vehicle to one or more road users. ### Claim 11 (depends on 1) The illumination module of claim 1, wherein the illumination module is configured to synchronously provide the coded pattern for detection by the image sensor. ### Claim 12 (depends on 11) The illumination module of claim 11, wherein the coded pattern is employed as a confirmatory feature for operation of the image sensor. ### Claim 13 (depends on 1) The illumination module of claim 1, wherein the illumination module is configured to asynchronously provide the coded pattern for detection by the image sensor. ### Claim 14 An illumination method, comprising: causing, by a controller operatively coupled to a set of light emitting diodes (LEDs) configured to provide illumination, the set of LEDs to operate in a first phase providing a coded pattern detectable by an image sensor; and causing, by the controller, the set of LEDs to operate in a concurrent second phase providing illumination perceivable by a person, wherein the coded pattern is not perceivable by the person. ### Claim 15 (depends on 14) The illumination method of claim 14, wherein the controller causes the LEDs to operate in the first and second phases according to a selected duty cycle. ### Claim 16 (depends on 14) The illumination method of claim 14, wherein the coded pattern is selected to complement user information provided by the set of LEDs that is perceivable by the person. ### Claim 17 (depends on 14) The illumination method of claim 14, wherein the controller causes the LEDs to synchronously provide the coded pattern for detection by the image sensor. ### Claim 18 (depends on 14) The illumination method of claim 14, wherein the controller causes the LEDs to asynchronously provide the coded pattern for detection by the image sensor. ### Claim 19 (depends on 14) The illumination method of claim 14, wherein the coded pattern is employed as a confirmatory feature for operation of the image sensor. ### Claim 20 (depends on 14) The illumination method of claim 14, wherein the coded pattern is configured to provide information regarding operation of a vehicle to one or more road users.
