Patent number: 10539289Abstract: A laser lighting module for a vehicle headlight includes at least one laser, a scanning arrangement, a light conversion device, a safety mirror, a safety detector and a safety controller. The laser emits light in a first wavelength range and the scanning arrangement moves a beam of the light within a scanning solid angle so a spot of the light moves across the light conversion device. The light conversion device converts a fraction of the light to converted light in a different wavelength range than the first and emits a mixture of transmitted and converted light. The safety mirror is arranged within the scanning solid angle such that at least 90% of the transmitted light hits the safety mirror. The safety controller receives the control signal, generated by the safety detector from the safety detection light, and switches off the laser if the control signal exceeds a first threshold value.Type: GrantFiled: April 19, 2019Date of Patent: January 21, 2020Assignee: LUMILEDS HOLDING B.V.Inventors: Hans Helmut Bechtel, Thomas Diederich

Patent number: 9082937Abstract: The present invention relates to a LED module which converts pump light from a LED chip (120) to light at another wavelength, which is emitted from the module. The conversion takes place in a portion of a luminescent material (124). The color purity of the LED module is enhanced by reducing any leakage of pump light using a reflector in combination with an absorber. In one embodiment, the absorber is integrated as one or several thin absorbing layers between the layers of a multi-layer reflection filter (126); this may yield an even higher reduction of pump light leakage from the module.Type: GrantFiled: March 12, 2013Date of Patent: July 14, 2015Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Hendrik Adrianus van Sprang, Hendrik Johannes Boudewijn Jagt, Berno Hunsche, Thomas Diederich
