Abstract
A mobile device is provided comprising a light guide modified at a plurality of locations to let light guided in the light guide at least partially escape. Furthermore, methods and apparatuses for manufacturing such mobile devices are provided.
Claims15
A mobile device, comprising:
- at least one light source configured to emit light in the visible range,
- a light guide coupled to said light source configured to guide light emitted by said at least one light source through said mobile device,
- said light guide being modified at a plurality of locations to let at least part of the light guided within the light guide escape at said locations, wherein a first location of said plurality of locations is configured to let light of a different wavelength range escape from the light guide than a second location of said plurality of locations.
A method of manufacturing a mobile device, comprising:
- providing a light guide,
- structuring said light guide such that light guided in the light guide is allowed to escape the light guide at a plurality of predetermined locations, and
- incorporating the light guide in a mobile device,
- wherein the structuring step comprises irradiating said light guide with a laser beam.
1 more element
An apparatus for manufacturing a mobile device, comprising:
- a laser,
- a diffractive optical element configured to receive a laser beam from said laser and to guide the laser beam over a light guide so as to create a plurality of locations in said light guide where light guided in said light guide may escape the light guide,
- wherein said light guide is to be incorporated into a mobile device for illuminating parts thereof.
A mobile device, comprising:
- at least one light source configured to emit light in the visible range,
- a light guide coupled to said light source configured to guide light emitted by said at least one light source through said mobile device, wherein said light guide is modified at a plurality of locations to let at least part of the light guided within the light guide escape at said locations, and
- a light transmitter configured to couple light modulated depending on data to be transmitted into said light guide and a light receiver coupled to said light guide configured to receive said modulated light and demodulate said light to retrieve said data,
- the light guide, the light transmitter, and the light receiver configured to communicate with each other internally within the mobile device.
