The present disclosure describes light conversion modules each having a single laser diode or multiple laser diodes. The light conversion modules can be particularly small in size (height and lateral footprint) and can overcome various challenges associated with the high optical power and heat emitted by laser diodes. In some implementations, the light conversion modules include glass phosphors, which, in some instances, can resist degradation caused by the optical power and/or heat generated by the laser diodes. In some instances, the light conversion modules include optical filters which, in some instances, can reduce or eliminate human eye-safety risk.

The invention relates to a lamp (1) comprising a lamp housing (2), a light source (3) disposed in the lamp housing (2), a reflection device (4) associated with the light source (3) for deflection of light emitted by the light source (3) in the direction of a light outlet opening (5) of the lamp housing (2), and a cooling device (6) associated with the light source (3) and/or with the lamp housing (2). In particular an inner side (7) of the lamp housing (2) is formed at least in some locations as the reflection device (4) and/or the cooling device (6) is formed in one piece with the lamp housing (2).

A dome light assembly that includes a reflective surface facing an interior; a light-diffusing element over the reflective surface having a plurality of corresponding opposed edges and LED sources; and a controller for directing the sources to transmit a plurality of light patterns from the element into the interior based at least in part on a plurality of inputs. Further, each source is configured to direct incident light into the corresponding edge. These light patterns include natural light and other light patterns. The inputs include manual inputs, weather inputs, exterior light sensor inputs, temporal inputs and global positioning system inputs.

An electronic device with a e-paper display that internally integrates photovoltaic cells and are not apparent from the exterior of the device. A light source of the device injects light into a light guide to front-light the e-paper. Light that leaks from edges of the light guide is captured by the photovoltaic cells. The plastic light guide is also impregnated with a photoluminescent material that absorbs near infrared energy that is incident on a face of the display and re-emits it isotropically to be guided by the light guide to the photovoltaic cells. By combining multiple techniques to illuminate hidden photovoltaic cells, the utility of the hidden cells is maximized.
