  • Patent number: 9080757
    Abstract: A bulb-type lamp having both heat dissipation and size/weight reduction properties with a lower thermal load on a lighting circuit. An LED module is mounted in a case with a base member to allow dissipation of heat. An LED mount member closes another end of the case and allows conduction of heat to the case. A lighting circuit receives power via the base member. The lighting circuit is disposed inside a circuit holder. An air space exists between the circuit holder and both the case and the mount member. The lighting circuit is isolated from the air space by the circuit holder. A relationship 0.5?S1/S2?3.0, is satisfied where S1 denotes an area of a portion of the mount member in contact with the case and S2 denotes an area of the portion of the mount member in contact with a substrate of the LED module.

  • Patent number: 9048400
    Abstract: A light-emitting device (1) includes a base (10), a light-emitting element (11) placed on the base (10), and a wavelength converting layer (12) that covers the light-emitting element (11). The wavelength converting layer (12) includes a wavelength converting portion (13) that converts a wavelength of light from the light-emitting element (11), and a light guide portion (14) made of a light-transmitting material, and the light guide portion (14) extends from a light-emitting element (11) side to a light extraction side of the wavelength converting layer (12). Consequently, it is possible to provide a light-emitting device that can be miniaturized and reduced in thickness easily and can prevent a decrease in the light extraction efficiency.
