  • Publication number: 20110261572
    Abstract: There is provided a lighting fixture 11 capable of efficiently radiating heat of a lamp device 14 attached to a socket device 13. By attaching the lamp device 14 to the socket device 13, a cap portion 38 of the lamp device 14 is brought into contact with a fixture body 12, and pressed against and brought into close contact with the fixture body 12 by an elastic body 30. Heat generated by lighting of LEDs 35 of the lamp device 14 is conducted from the cap portion 38 to the fixture body 12 and efficiently radiated.

  • Publication number: 20110089806
    Abstract: The present invention provides a light-emitting element lamp 1 capable of preventing a temperature rise of a substrate 9, on which light-emitting elements 4 are mounted, by effectively utilizing a thermally conductive casing 2 and a thermally conductive cover 5. The light emitting element lamp 1 includes a thermally conductive casing 2, a light source part 3, a thermally conductive cover 5, and an insulative cover 6. The thermally conductive casing 2 includes an irradiation opening 2b, is formed so as to be widened toward the irradiation opening 2b, has its outer circumferential surface exposed outwardly, and has a substrate mounting part 2c secured on its inner circumferential surface. The light source part 3 has a substrate 9 having the light-emitting elements 4 mounted thereon and causes the substrate 9 to be thermally coupled to and attached to the substrate mounting part 2c of the thermally conductive casing 2.

  • Publication number: 20110074291
    Abstract: A light-emitting module includes a module substrate, semiconductor light-emitting elements and a connection substrate. On one face of the module substrate, a conductive layer is formed. The semiconductor light-emitting elements and the connection substrate are mounted on the conductive layer of the module substrate. Electric wires, which extend from a lighting circuit, are connected to the connection substrate. Power is supplied to the semiconductor light-emitting elements through the connection substrate and the conductive layer of the module substrate.

  • Publication number: 20100327751
    Abstract: The present invention provides a self-ballasted lamp which efficiently conducts heat of a plurality of LED chips of a light emitting module to its holder, and can prevent the temperature rise of the LED chips. The holder has a base portion, an edge portion provided at one end side of the base portion, which is thick at the base portion side thereof and thin at the distal end side thereof, and heat radiation fins provided at the other end side from the edge part and at the circumference of the base portion. The heat from the semiconductor light emitting elements is conducted from the base portion to the edge part and radiated therefrom. At this time, the edge part is thickened at the base portion side, wherein the thermal capacity is increased, and the heat conduction is improved.

  • Publication number: 20100289396
    Abstract: 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.
