Embodiment Construction

[0061] Hereinafter, the light emitting module and the lighting device in the embodiment will be described with reference to the drawings. The components having the same functions in the embodiments are denoted by the same symbols, and redundant descriptions are omitted. In addition, the light-emitting module and illuminating device demonstrated in the following embodiment are just an example, and do not limit this invention.

[0062] In the following embodiments, the light-emitting module includes a substrate formed of an insulating resin, and the light-emitting element is arranged on the first surface of the substrate along the long-side direction from the first end to the second end of the substrate. The first group of light-emitting element groups connected in series with each other. In addition, the light-emitting module includes: a second conductive wire, which is arranged on the second surface of the substrate opposite to the first surface from the first end to the seco...

Abstract

According to one embodiment, a light-emitting module includes N light-emitting elements, which are a first group of light-emitting elements, on the front surface of a substrate. The N light-emitting elements are disposed in a row in a longitudinal direction from one end portion to the other end portion of the substrate. The N light-emitting elements are connected in series. The light-emitting module includes a metal member provided in the longitudinal direction of the substrate in a position not overlapping a conductive line on the rear surface of the substrate. The conductive line is connected to, via a through-hole, a conductive line configured to connect the N light-emitting elements.

Description

technical field [0001] The invention relates to a light emitting module (module) and a lighting device. Background technique [0002] In recent years, a chip-on-board (COB) method in which a plurality of LED chips (chips) are mounted on a substrate has generally been adopted as a light-emitting module using a light emitting diode (Light Emitting Diode, LED). [0003] A COB-type light emitting module is used, for example, in a light bulb type LED lamp (lamp). In bulb-type LED lamps, collective mounting type (type) light-emitting modules are used. In this collective mounting type light-emitting module, flow stoppers are formed on a substrate on which a plurality of LED chips are collectively mounted, and phosphor resin flows into the flow stoppers. It is formed in the formed space and hardened. [0004] Furthermore, in recent years, COB-type light-emitting modules can also be used in straight-tube LED lamps. In straight-tube LED lamps, a light-emitting module in which LED c...
