A lens includes a first lens section and a second lens section, which are integrally formed. The first lens section is formed in a hemispherical shell shape including a first recess opened toward one side of an optical axis direction in which light from a light source is made incident. The second lens section is formed in a hemispherical shell shape including a second recess opened toward the other side of the optical axis direction.

Bulb-type lamp

A light-emitting device includes a substrate having a front surface on which a semiconductor light-emitting element is mounted. A front cover is provided which thermally contacts the front surface of the substrate at a periphery of the semiconductor light-emitting element and is disposed on a front side of the substrate. A heat conduction path is formed along which heat generated by the semiconductor light-emitting element is conducted in order of the substrate and the front cover and the heat is radiated from a front surface of the front cover, so that a heat radiation property from a front surface of the light-emitting device is improved.

Light-emitting device and lighting apparatus

In a lamp deviceusing a GX53-type capand also using an LEDas a light source, there is regulated an appropriate configuration of a metallic cover. A capand a lighting deviceare arranged on an upper surface side of the metallic cover, and a substrateon which the LEDis mounted is arranged on a lower surface side thereof. The metallic coverhas an approximately cylindrical shape with a maximum outer diameter D of 80 to 150 mm, a height H of 5 to 25 mm, and 2&#x3c0; (D/2) H/W, that is, an area of the outer peripheral surface per gross input power W to the lamp devicebeing in a range of 200 to 800 mm/W. The gross input power W is 5 to 20 W.

Lamp device and lighting fixture including LED as light source and metallic cover

A self-ballasted lamp includes a base body, a light source unit attached to one side of the base body, a lens attached to the light source unit, a cap provided on the other side of the base body and a lighting circuit arranged in the space provided by the base body and the cap. The light source unit includes a light source constituted by semiconductor light emitting elements. The lens has a lens body facing the light source and an attachment leg for attaching the lens body to the light source unit. A claw portion to be secured to the light source unit can be provided on the attachment leg.

Self-ballasted lamp and lighting fixture

A lighting device and a lighting fixture of the embodiment of the present invention comprises a thermally conductive main body having a substrate support portion in one end portion, and having a through-hole and a groove portion formed in the substrate support portion, the through-hole penetrating from the one end portion to the other end portion of the main body, the groove portion extending continuously from the through-hole, a substrate mounted with a semiconductor light-emitting device, and disposed on the substrate support portion, an electrical connector connected to the semiconductor light-emitting device, a power supply device housed in the main body and configured to light the semiconductor light-emitting device, a wire connected to the power supply device and to the electrical connector while being inserted through the through-hole and the groove portion, and a base member provided in the other end portion of the main body and connected to the power supply device. Therefore, a lighting device and a lighting fixture of this embodiment of the present invention reduced in size, is configured to be suitable for mass production and is capable of producing a certain luminous flux.
