Abstract

According to one embodiment, a lighting apparatus includes a conductive main body at a ground potential, a light-emitting device (1) in the main body, and a lighting control device configured to supply power to the light-emitting device. The light-emitting device includes a substrate (2) including an insulation layer (22), and a radiation layer (23) with a thermal conductivity, formed of conductive material and laminated on the insulation layer, a plurality of light-emitting elements (3) mounted on the radiation layer, and a power supply wiring (4) configured to electrically connect the light-emitting elements and to make the radiation layer electrically nonconductive.

Description

technical field [0001] The present invention relates to an illuminating device, in particular to an illuminating device using light-emitting components such as light emitting diodes (light emitting diodes, LEDs). Background technique [0002] Recently, LEDs are being used as light sources of lighting devices. The light source is a bare chip with a plurality of LEDs disposed on a substrate, and each LED chip is electrically connected to a wiring pattern with a bonding wire to be packaged on the substrate. And, this board|substrate is assembled|attached to the main body made of metal, such as aluminum, and LED lighting apparatus is comprised (for example, refer patent document 1). [0003] In such a conventional lighting device, power is usually supplied from a lighting device connected to an AC power source, and lighting control of LEDs is performed. Furthermore, the metal body is at ground potential. [0004] [Background Art Document] [0005] [Patent Document] [0006]...
