Patent number: 10788708Abstract: It is an object to provide a technique capable of enhancing evenness of a planar light. A planar light source device includes a light source, a holding substrate, a light distribution control element having a light incident surface and a light outputting surface, a reflection part reflecting the light which has been reflected in an inner side of the light distribution control element toward the side of the display surface, and a case which houses the light source, the holding substrate, the light distribution control element, and the reflection part. A part opposite to the side of the display surface, in relation to at least the light distribution control element in a region between the light distribution control element and an inner wall of the case, is covered by the reflection part.Type: GrantFiled: July 21, 2017Date of Patent: September 29, 2020Assignee: MITSUBISHI ELECTRIC CORPORATIONInventors: Tomohiko Sawanaka, Masaaki Takeshima, Saki Maeda, Masayoshi Aoshima, Kengo Nishikawa

Patent number: 7447243Abstract: A laser emitting module, a window cap thereof, a laser pointer using the same and a light emitting module are provided. A light emitted from a laser diode excites a solid-state laser medium so as to generate lights of different wavelengths, the wavelength of which is converted in a non-linear optical element so as to emit a laser beam of a short wavelength by second harmonic generation. An optical resonator including the solid-state laser medium and the non-linear optical element is supported by a base member. Heat of the laser diode and the optical resonator is dissipated via a heat sink which is in contact with the laser diode and the base member, thereby stabilizing temperatures of respective elements and thus the generation of the laser beam.Type: GrantFiled: August 29, 2005Date of Patent: November 4, 2008Assignee: Sony CorporationInventors: Masayoshi Aoshima, Eiji Otani

Patent number: 7192153Abstract: A lens, a light irradiation apparatus and a laser pointer to which the lens is applied to are provided, in which eccentricity, discrepancy of light axes, uneven gap of lens surfaces and the like are reduced without performing positioning of respective lenses; and cost of manufacturing a lens having a plurality of functions can be reduced. A lens according to the present invention is the lens, in which a light diameter expanding element for expanding a diameter of incident light and a light collimating element for projecting approximately collimated light after receiving the incident light having the diameter thereof expanded by the light diameter expanding element are integrally formed in advance as a lens of one unit.Type: GrantFiled: April 30, 2004Date of Patent: March 20, 2007Assignee: Sony CorporationInventors: Masayoshi Aoshima, Kyu Kanno
