Patent number: 11739912Abstract: An aircraft lamp includes: a lamp outer housing configured by a lamp housing having an opening and a cover attached to the lamp housing in a state where the opening is closed, wherein an internal space is formed as an arrangement space; a light source unit arranged in the arrangement space and having a light source; and a control unit including a control substrate that controls an ON/OFF of the light source, and a shielding plate that shields noise generated in the control substrate. The lamp housing is provided with a unit accommodation portion having a concave shape and an insertion/removal port. The control substrate is configured to be accommodated in and removed from the unit accommodation portion via the insertion/removal port. At least a part of the insertion/removal port is closed by the shielding plate in a state where the control substrate is accommodated in the unit accommodation portion.Type: GrantFiled: July 9, 2020Date of Patent: August 29, 2023Assignee: KOITO MANUFACTURING CO., LTD.Inventors: Michio Tsukamoto, Shigeo Sawada

Patent number: 9279563Abstract: Provided is a lamp configured to control an irradiation angle. The lamp includes a light emitting unit that is provided with an LED and a reflector having a reflecting surface that reflects light from the LED. The reflecting surface of the reflector is formed to have a parabolic shape in a cross-section perpendicular to an optical axis of the LED. The reflecting surface of the reflector is formed to have an elliptical shape in a cross-section parallel to the optical axis of the LED so as to condense and diffuse reflected light beams in a forward direction.Type: GrantFiled: October 23, 2013Date of Patent: March 8, 2016Assignee: Koito Manufacturing Co., Ltd.Inventors: Shigeo Sawada, Hiroto Shimizu, Tomoya Nishihara

Patent number: 8297811Abstract: An aircraft lamp includes a housing capable of being attached to a body of an aircraft; a discharge lamp; a reflector which reflects visible light from the discharge lamp; a light transmissive cover which transmits reflected light from the reflector to a front side of the housing; a lamp socket connected electrically to the discharge lamp and an igniter which activates the discharge lamp; and a high-voltage electrical power line that electrically connects the lamp socket with the igniter. The discharge lamp, the reflector, the light transmissive cover, the lamp socket, and the igniter are provided within the housing. A heat insulating air layer is provided between the lamp socket and the igniter. The high-voltage electrical power line is provided so as to pass through the heat insulating air layer.Type: GrantFiled: July 27, 2009Date of Patent: October 30, 2012Assignee: Koito Manufacturing Co., Ltd.Inventors: Tomoyuki Mukai, Makoto Nawa, Shigeo Sawada

Publication number: 20090225560Abstract: A compact aircraft external illumination lamp has a discharge bulb as a light source that ensures a waterproof property. The aircraft external illumination lamp includes a container-shaped reflector serving also as a lamp body, a front cover attached to a front opening of the reflector, and a discharge bulb inserted in a bulb insertion hole formed in the reflector. A power supply socket is attached to a back side of the reflector so as to cover a peripheral edge of the bulb insertion hole. The power supply socket thus longitudinally fits on a plug portion of the discharge bulb which projects rearward of the bulb insertion hole, whereby electric connection with the discharge bulb is ensured. The power supply socket is structured so that a bulb activation circuit is embedded therein and a socket main body having a plug-portion fitting hole formed on a front side thereof is covered with a resin mold layer.Type: ApplicationFiled: February 25, 2009Publication date: September 10, 2009Applicant: Koito Manufacturing Co., Ltd.Inventors: Tomoyuki Mukai, Shigeo Sawada
