  • Patent number: 8100649
    Abstract: In a ceiling fan having a blade surface light, an annular blade surface light including a plurality of LEDs that are light emitters that are continuously placed is secured on a circumference that connects sides near tips of a plurality of rotary blades of the ceiling fan, and the light emitters are lit by a lighting controller only when they are in a predetermined range on a rotation reference circumference. LED devices housing the LEDs that are the light emitters and that are provided with cooling fins are housed in an annular LED case, and the LED case is secured to the rotary blades. Thus, the LEDs radiate heat from the cooling fins provided in the LED devices by rotation of the rotary blades, and they are intermittently lit and extinguished to prevent a temperature increase. The LEDs only in the predetermined range are lit, thereby preventing any uncomfortable feeling when LEDs are caused to flash.

  • Patent number: 8022429
    Abstract: A light emitting device includes a light emitting element (LEE) on a mounting board, a metal reflector surrounding the side surfaces of the LEE on the mounting board, a conductor electrically connecting the LEE with the mounting board, and a sealing resin fitted within the reflector to cover and seal the LEE and the conductor. The mounting board includes a metal baseboard, and an insulating board laminated on the base board with a window hole larger than the outer periphery of the LEE. A mount for the LEE is on the base board within the window hole with a clearance defined from window hole side surfaces. The conductor straddles the clearance, and electrically connects the wiring pattern on the insulating board with the LEE and mount. Part of the clearance associated with the area that projects from the conductor to the mounting board is narrower than the remainder.
