Each of the two power-supply leads extends from a side of the base toward inside of the globe and connected to the base board, and the LED chip is provided between a portion at which one of the two power-supply leads and the base board are connected and a portion at which the other of the two power-supply leads and the base board are connected.

A light bulb shaped lamp according to the present invention includes: a hollow globe; an LED module including a base platform and an LED chip mounted on the base platform, the LED module being provided in the globe; a lead wire for supplying power to the LED module; and a stem extending toward the interior of the globe, in which the base platform is directly fixed to the stem.

Light bulb shaped lamp and lighting apparatus

An LED lamp has an envelope that includes a globe and a case, an interior space of the envelope being divided in two by a mount closing an opening of the globe, the lamp containing, in a globe side of the interior space, an LED and, in a case side of the interior space, a circuit unit for causing the LED to emit light. The LED is thermally connected to the mount, and the mount and the case are joined to the globe such that, during light emission, at least as much heat from the LED is propagated from the mount to the globe as from the mount to the case.

LED lamp and lighting device

A lamp includes an LED module, a drive unit supplying power to the LED module, and a base via which power is fed from an external power supply to the drive unit. The drive unit is located between the LED module and the base. The drive unit includes a circuit board having a main surface on which lead-type electronic components are mounted, lead wires (first lead wires) extending from the main surface of the circuit board and connected to the LED module, and lead wires (second lead wires) extending from the main surface of the circuit board and connected to the base. The circuit board has a through-hole extending from the main surface to an opposite surface thereof. The lead wires pass through the through-hole.

Light

In a lamp: an LED module and a circuit unit for lighting are housed within an envelope composed of a globe and a case; the LED module is attached to an end of an extension member that extends from a mount, which closes an opening at one end of the case, into the globe; the circuit unit is mounted inside the case; an insulation member disposed inside the case ensures insulation between the mount, which is made of metal, and the circuit unit; the insulation member has a bottomed cylinder portion inserted into the mount, and a protrusion portion formed on an outer circumference of the based cylinder portion that protrudes toward an inner surface of the mount; and the insulation member is attached to the mount by the protrusion portion pressing against the inner surface of the mount.

Lamp having improved insulation of the circuit unit

A light-emitting device according to the present invention includes: a package which is translucent; an LED provided in a recess in the package; and a sealing member for sealing the LED and packaging the recess; and the recess includes a bottom surface on which the LED is mounted and a side surface surrounding a bottom surface, and light emitted by the LED is transmitted inside the package through the bottom surface and the side surface of the recess and is emitted to outside of the package from the back surface and the side surface of the package.

Light-emitting device, light-emitting module, and lamp

An object of the present invention is to provide a mounting substrate, a manufacturing method, a light-emitting module and an illumination device that can sufficiently improve the luminous efficiency of an LED lamp. A mounting substrate according to the present invention includes a substrate and a reflective film that is formed on a front surface of the substrate and has a front surface on which LED chips are to be mounted, and the reflective film is made of metal oxide microparticles and a glass frit, and reflects light from the LED chips.

Mounting substrate and manufacturing method thereof, light-emitting module and illumination device

A mount member () has a contact surface () touching the bottom surface of an LED module () and protrusions () protruding from the periphery of the contact surface () in the thickness direction of the LED module () and regulating sliding motions thereof. A fixing member () made of a resilient, plate-like member comprises an opposing pair of flat portions () near the contact surface () of the mount member () and flat tabs () projecting from the flat portions () toward the contact surface () touching the upper surface of a substrate (). The flat portions () of the fixing member () are fastened to be lower than the top surface of the substrate () of the LED module (). Thus, elastically deformed areas extending from the fastened parts of the flat portions () through the flat tabs () press the substrate () into the mount member ().
