A method to make light-emitting diode (LED) units include arranging LEDs in a pattern, forming an optically transparent spacer layer over the LEDs, forming an optically reflective layer over the LEDs, and singulating the LEDs into LED units. The method may further include, after forming the optically transparent spacer layer and before singulating the LEDs, forming a secondary light-emitting layer that conforms to the LEDs, cutting the LEDs to form LED groups having a same arrangement, spacing the LED groups on a support, and forming the optically reflective layer in spaces between the LED groups.

A flash light module () can include a housing () carrying at least a visible flash light emitter () to emit a flash light beam along an optical axis (OA) and at least one additional emitter () emitting non-visible light arranged at a second distance (D) perpendicular to the optical axis (OA), where position and orientation of the additional emitter () and at least the second distances (D) are suitably adapted as well as the housing () is suitably shaped in order to enable the additional emitter () to emit non-visible light () along a non-visible light emitting direction (IRD), wherein the additional emitter () is adapted to emit the non-visible light () to the environment suitable to remote communicate to, preferably to remote control, external electronic devices () comprising corresponding receivers for the non-visible light (). A mobile device () can include the flash light module () and a method to operate the mobile device ().

Flash light emitter with remote communication function

A light emitting structure includes a packaged back-emitting light emitting device mounted on a reflective substrate. The properties of the reflective surface may be controlled to provide a desired luminance pattern. In this manner, the creation of a light emitting structure that provides a desired luminance pattern may be independent of the provider of the packaged light emitting device.
