Patent number: 7728508Abstract: A light-emitting device can be configured to have little variation in light emission characteristics even at increased temperatures. A light-emitting device can include a light-emitting section for emitting light with a predetermined wavelength, and a fluorescent material for absorbing a part of light emitted from the light-emitting section and emitting light with a longer wavelength. The light-emitting device can mix the light with the predetermined wavelength from the light-emitting section and the light with the longer wavelength from the fluorescent material, and thereby emit a mixed light. The fluorescent material can include single crystal grains in which primary grains have a diameter of 1 ?m or less. Crystal defects, such as a grain boundary, do not often and sometimes never occur in the single crystal grain having a diameter of 1 ?m or less.Type: GrantFiled: June 7, 2005Date of Patent: June 1, 2010Assignee: Stanley Electric Co., Ltd.Inventors: Kenichi Kondo, Shuichi Taya, Yasuyuki Miyake

A lighting apparatus can also be configured for use with such a reflector film. The reflector film can include a silver or silver alloy film deposited on a substrate, and a titanium or titanium alloy film deposited on the silver or silver alloy film to serve as a protective film.Type: ApplicationFiled: February 7, 2008Publication date: December 18, 2008Inventors: Yoshio Suzuki, Shuichi Taya

Patent number: 7309881Abstract: A wavelength-converting LED can include a light-emitting section in which an exciting element emits a blue or ultraviolet light. A fluorescent material that has a mean particle diameter D50 ranging from 5 ?m to 20 ?m and that can convert at least part of the light emitted from the exciting element into light having a wavelength longer than an exciting wavelength, can be incorporated into the LED. A dispersing agent with a mean particle diameter D50 not less than 1/10 of the mean particle diameter D50 of the fluorescent material is preferably incorporated in the LED. A binder base material can be arranged to contain the fluorescent material, the dispersing agent and a binder therein. The sum of the weights of the fluorescent material and the dispersing agent is preferably in the range of 20% to 60% by weight of said binder base material to prevent the fluorescent material from precipitating in the binder base material upon curing.Type: GrantFiled: July 28, 2004Date of Patent: December 18, 2007Assignee: Stanley Electric Co., Ltd.Inventors: Hiroyuki Sato, Shuichi Taya
