Abstract

The present invention provides a light-emitting device and a lighting device, which are composed of a solder-free electrical connection mechanism capable of suppressing the reduction of the light-emitting effect. A light-emitting device (10) is constituted, and the light-emitting device (10) includes: a substrate (11) on which a wiring pattern and a power supply terminal are formed on one side; a light-emitting element (12) mounted on one side of the substrate; and a conductive connection The device member (13) has at one end a substrate-side contact portion (13a) in contact with the power supply terminal (11d) of the substrate, and at the other end has a wiring connection portion (13b) to which a wiring (w1) for power supply is connected. ), and the other end portion is extended on the other side facing the one side of the substrate.

Description

technical field [0001] The present invention relates to a light-emitting device and a lighting device using a light-emitting element such as a light-emitting diode (diode) as a light source. Background technique [0002] In recent years, light-emitting devices using light-emitting elements, especially light-emitting diodes, have been used as various types of light-emitting diode (Light Emitting Diode, LED) lamps, downlights, and spotlights that can replace incandescent light bulbs. It is a light source for a variety of lighting equipment, and is expanding into various aspects such as thin TVs (televisions), liquid crystal displays (displays), mobile phones, backlights of various information terminals, and indoor and outdoor sign advertisements. In addition, because of its long life, low power consumption, impact resistance, high-speed response, high-purity color display, and compactness, it is not only used in general lighting, but also in various industrial fields.
