Patent number: 8835875Abstract: To overcome the disadvantages introduced by using UV sensors to detect the intensity of UV light in water purification apparatuses, a novel detection apparatus to “visualize” the quality of water in the form of visible light, instead of digitizing the intensity of UV light includes s a first detection window, coated with a first material for converting a received first ultraviolet light into a first visible light. The first ultraviolet light is emitted from an ultraviolet light source and traverses the liquid, and the detection apparatus further mixes the first visible light with second visible light to generate a third visible light. The different color of the third visible light can represent the different quality of the water.Type: GrantFiled: January 4, 2011Date of Patent: September 16, 2014Assignee: Koninklijke Philips N.V.Inventors: Jun She, Levinus Pieter Bakker, Cornelis Reinder Ronda

The illumination apparatus comprises a light guide plate and a light source configured to emit light into the light guide plate through a first surface, and the light guide plate comprises a concentrator configured to direct incident light in the light guide plate so as to radiate in a direction substantially parallel to a preset plane. The preset plane is perpendicular to any one of the top surface and bottom surface of the light guide plate, and intersects the first surface and a second surface of the light guide plate or intersects the first surface and one of the side surfaces at an angle that is substantially larger than the critical angle of a total reflection. In this way, unwanted light loss in the light guide plate is reduced, and the distribution of the light intensity or luminance along the light guide plate is improved, i.e., a substantially uniform distribution of the light intensity can be achieved.Type: ApplicationFiled: June 7, 2010Publication date: June 28, 2012Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Levinus Pieter Bakker, Jun She, Hugo Johan Cornelissen, Gongming Wei
