Publication number: 20230149077Abstract: According to an aspect, there is provided a personal care device (52) for performing a light-based hair removal or photo-epilation operation on a body of a subject. The personal care device (52) comprises a housing (54) that includes a first window or opening (68), a light source configured to generate light to perform the light-based hair removal or photo-epilation operation, wherein the light source is arranged in the housing such that light emitted by the light source illuminates a part of the body, a receiving member in or on the housing (54) for receiving and retaining a consumer electronic device (62) in or on the personal care device (52), and an optical system (80) in the housing (54) for enabling an imaging unit (78) of a consumer electronic device (62) retained in the recess (60) to obtain images of a part of the body via the first window or opening (68).Type: ApplicationFiled: April 14, 2021Publication date: May 18, 2023Inventors: Edgar VAN GOOL, Felix Godfried Peter PEETERS, Marjolein Yvonne JANSEN, Eyob Atanfu AMRA, Eric Gerard Marie VAN KEMPEN, Lars Christian CASPER, Wilbert Bernard Roger PENNINGS, Tim TIELEMANS

Patent number: 9157583Abstract: The invention provides a lighting device (100) comprising a light source (10) and luminescent materials (20). The luminescent materials (20) comprise a first organic luminescent material (120) and a second organic luminescent material (220), the light source (10) together with the luminescent materials (20) being configured to generate white lighting device light (101) during operation. The first organic luminescent material (120) degrades with time at a first degradation rate and the second organic luminescent material (220) degrades with time at a second degradation rate, wherein the first degradation rate is larger than the second degradation rate. The first organic luminescent material is configured in a first layer (130, 1020) and the second organic luminescent material is configured in a second layer (140, 1220).Type: GrantFiled: March 22, 2013Date of Patent: October 13, 2015Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Ties Van Bommel, Rifat Ata Mustafa Hikmet, René Theodorus Wegh, Martinus Petrus Joseph Peeters, Gerardus Wilhelmus Gerbe Van Dreumel, Lars Christian Casper

Patent number: 8939607Abstract: This invention relates to an optical device (100) for intercanopy lighting comprising a light input area (109) for receiving light, a first surface (120) having a first bezier curve, and a second surface (110) having a second bezier curve. The first and second bezier curves are independently selected with respect to each other, and arranged such that the optical device is rotational asymmetric with respect to its center axis. Received light which is reflected in the first surface is reflected in a direction towards the center axis, and received light which is reflected in the second surface is reflected in a direction away from the center axis, thereby providing vertical and horizontal homogeneous illumination distribution in a predefined area, which area is illuminated under an angle.Type: GrantFiled: February 23, 2011Date of Patent: January 27, 2015Assignee: Koninklijke Philips N.V.Inventors: Lars Christian Casper, Christina Tanase
