Publication number: 20160258609Abstract: An LED lighting apparatus includes an LED light-emitting unit, a radar detector, a controller, and a translucent cover. The LED light-emitting unit has a plurality of LED chips. The radar detector transmits radio waves, receives radio waves reflected by an object, and detects a movement of the object based on a change in a wavelength of the received radio waves. The controller controls light emission of the LED light-emitting unit based on a result of the detection by the radar detector. The translucent cover covers the LED light-emitting unit in a main emission direction in which a center of the light emitted from the LED light-emitting unit travels, and allows light from the LED light-emitting unit and the radio waves from the radar detector to pass through. The radar detector is surrounded by the LED light-emitting unit in the main emission direction.Type: ApplicationFiled: February 24, 2016Publication date: September 8, 2016Inventors: Yoshifumi FUJIMOTO, Hirotaka SHIMIZU, Hideharu OSAWA, Hiroki YONEDA

Patent number: 8755918Abstract: The exchange time information to be acquired from an LED illumination lamp by an illumination instrument or the exchange time information to be stored by the illumination instrument itself is recognized by a controller via an ON/OFF control-dedicated switch control line or a general-purpose power line. The exchange time information is acquired in an OFF period of the LED illumination lamp ON-period noise. The exchange time information acquisition function is checked on a daily basis so as to cope with an alarm after a long period. The exchange time check result is stored so as to execute the alarm at an appropriate timing. The exchange time information held by the LED illumination lamp itself is transmitted firstly to the illumination instrument by simple information transmission means. The information is recognized by using a control path existing between the illumination instrument and the controller at hand.Type: GrantFiled: November 25, 2009Date of Patent: June 17, 2014Assignee: Rohm Co., Ltd.Inventors: Hideharu Osawa, Masahide Tanaka

Patent number: 8425081Abstract: An LED lamp A1 includes a plurality of LED modules 30 and a hollow diffusion pipe 20 accommodating the LED modules 30. Each LED module 30 includes an LED 31, and a resin package 32 covering the LED 31. The resin package 32 includes a light emission surface 35 opposed to the inner surface 21 of the diffusion pipe 20 and internally diffuses the light from the LED 31 to allow the light to be emitted from the light emission surface 35. The light emission surface 35 and the inner surface 21 of the diffusion pipe 20 are spaced from each other by a distance that is smaller than the distance between the light emission surface 35 and the LED 31. The arrangement reduces light distribution non-uniformity while increasing the amount of light emission.Type: GrantFiled: May 28, 2009Date of Patent: April 23, 2013Assignee: Rohm Co., Ltd.Inventor: Hideharu Osawa
