Light-emitting module, straight tube lamp and luminaire

Abstract

The invention provides a light-emitting module, a straight tube lamp and a luminaire, by which a uniform light-emitting distribution can be obtained between the light-emitting modules. The light-emitting module (11) includes a rectangular substrate (20), at least two light-emitting circuits (21a, 21b) and inter-module connection parts (26a, 26b). The light-emitting circuit (21a, 21b) connects plural light-emitting elements (22a, 22b) in a longitudinal direction of the substrate. The inter-module connection parts (26a, 26b) include respective pairs of electrodes (27, 28) connected with the respective light-emitting circuits (21a, 21b) on an end of the substrate (20) in the longitudinal direction. The respective pairs of electrodes (27, 28) are arranged to be closer to side parts of the substrate (20) in a short direction thereof than an arrangement area of the light-emitting elements (22a, 22b) and are arranged side by side in the longitudinal direction of the substrate (20).

Description

technical field [0001] Embodiments of the present invention relate to a light emitting module having a connecting portion between modules, a straight tube lamp using the light emitting module, and a lighting fixture using the straight tube lamp. Background technique [0002] Conventionally, there has been a straight tube type lamp using a light emitting element such as a light emitting diode (Light Emitting Diode, LED) element. In this straight tube type lamp, a member in which a plurality of light emitting modules are arranged in a straight line is housed in a straight tube type cover, and bases are attached to both ends of the cover. [0003] The light emitting module has an elongated substrate, a plurality of light emitting elements are arranged along the longitudinal direction of the substrate, and one light emitting circuit in which the plurality of light emitting elements are connected in series is formed. At the end of the substrate, there is formed an inter-module c...

AI Technical Summary

Problems solved by technology

[0008] When more than two electrodes are arranged at the end of the substrate to connect the light-emitting modules, a plurality of electrodes should be arranged along the end of the substrate, and within the arrangement area of ​​a plurality of light-emitting elements along the long side direction of the substrate Electrodes must also be arranged. In this way, the pitch of the light-emitting elements between the light-emitting modules will become wider, so dark parts will be generated between the light-emitting modules, and it will not be possible to obtain a uniform light-emitting distribution throughout the light-emitting modules.
