Patent number: 8450915Abstract: An object of the present invention is to provide an LED bulb in which temperature of a lighting circuit is suppressed from rising during lighting of an LED so that life time of the lighting circuit is maintained without increasing manufacturing cost of components. According to the invention, an LED module 11 having multiple LEDs surface-mounted thereon is mounted in a heat dissipating unit 12. Heat generated by the LEDs is dissipated through multiple heat dissipating fins 18 of the heat dissipating unit 12. A glove 14, covering the LED module 11, radiates outward radiant light from the LEDs. A lighting circuit 17 for lighting the LEDs is incorporated in an inner hollow portion 23 of a cap 16 arranged on a side opposite to the glove 14 of the heat dissipating unit 12. Accordingly, the heat generated by the LEDs of the LED module 11 is mostly dissipated by the heat dissipating unit 12, thereby suppressing the temperature of the lighting circuit from rising.Type: GrantFiled: December 24, 2008Date of Patent: May 28, 2013Assignees: Toshiba Lighting & Technology Corporation, Kabushiki Kaisha ToshibaInventors: Shigeru Osawa, Kazuto Morikawa, Toshiya Tanaka, Takeshi Hisayasu
