Abstract: To accommodate variations in the interpupillary distances associated with different users, a head-mounted device may have left-eye and right-eye optical modules that move with respect to each other. Each optical module may have a display that creates an image and a corresponding lens that provides the image to an associated eye box for viewing by a user. The optical modules each include a lens barrel to which the display and lens of that optical module are mounted and a head-mounted optical module illumination system. The illumination system may have light-emitting devices such as light-emitting diodes that extend along some or all of a peripheral edge of the display. The light-emitting diodes may be mounted on a flexible printed circuit with a tail that extends a lens barrel opening. A stiffener for the flexible printed circuit may have openings that receive the light-emitting diodes.

The light source module includes at least a laser-pumped phosphor light source that includes a photoluminescent phosphor and a laser diode to generate laser light within a first wavelength range to pump the photoluminescent phosphor. Exposure of the photoluminescent phosphor to the laser light results in emission of visible light within a second wavelength range according to a laser-pumped emission spectrum associated with the photoluminescent phosphor.

Abstract: A light source module includes an illumination element and an adjustable light diffusing material. The light source module is configured to receive or generate a control signal for adjusting diffusion of light emitted from the light source module and accordingly adjust an amount of diffusion of light emitted from the light source module. In some embodiments, an adjustable light diffusing material includes a polymer stabilized cholesteric texture (PSCT), a smectic phase liquid crystal, a polymer network liquid crystal (PNLC), or other suitable material. A controller for a light source module may determine a level of diffusion based on a level of inclusion of a wide-angle field of view of a wide-angle lens system or a telephoto field of view of a telephoto lens system in a composite camera field of view that includes a combination of the wide angle field of view and the telephoto field of view.

Abstract: A lighting module which provides adjustably controllable illumination of a camera field of view of a camera module includes an adjustable collimator which can be adjustably positioned such that the emitted light beam is adjustably directed to illuminate various regions of various camera fields of view. The collimator can be adjusted via an actuator which adjustably positions the collimator relative to static components of the lighting module, including the light emitter. The light beam can be directed to illuminate a selected limited region of a camera field of view, based on identification of a subject within the limited region. The light beam can be adjustably directed based on user interactions with a user interface, including adjusting the light beam according to user-commanded beam angle, intensity, and direction. The light beam can be adjustably directed to illuminate a region according to different fields of view of different camera modules.

Abstract: A device which includes a display can provide adjustable light output, based in part on the color of the display screen output, to control the light output of the display screen. An illumination processor can adjustably control light output based on the colors of portions of the display screen. The light output can be adjusted to maintain the light output of the display screen across a range of colors of display screen light output. Controlling the light output of the display screen results in controlling the illuminance of a subject. The device can include a camera which captures an image of the subject and displays the image on a portion of the display screen, where the light output of a portion of the display screen can illuminate the subject such that the captured image has at least a certain level of image quality.
