Problems solved by technology

[0013] Furthermore, as the substrate becomes thinner, the metal wiring becomes thinner and thinner, and as the material of the metal wiring, instead of using low-resistance copper, silver with a relatively high resistance value is often used. Therefore, even if it is the same as conventional The width of the metal wiring also tends to increase the wiring resistance
In addition, metal wiring is often formed by printing, so it is also difficult to increase the thickness of the metal wiring to achieve low resistance.

Abstract

This substrate (10) to which a plurality of LEDs (30) are mounted linearly as an element array has first wiring (21) and second wiring (22) formed in a manner so as to sandwich the element array. The first wiring (21) has: a first primary wiring section (21b) extending primarily in the direction of arraying of the element array; and a first connecting section (21a) that is connected to the first primary wiring section (21b) and has a location for connecting to the LEDs (30). The second wiring (22) has: a second primary wiring section (22b) extending primarily in the direction of arraying of the element array; and a second connecting section (22a) that is connected to the second primary wiring section (22b) and has a location for connecting to the LEDs (30). The gap between the first primary wiring section (21b) and the second primary wiring section (22b) at LED mounting positions (30a) is greater than the gap between the first primary wiring section (21b) and the second primary wiring section (22b) at the other positions other than the LED mounting positions (30a).

Description

technical field [0001] The present invention relates to a substrate, a light-emitting device, and a lighting device, and particularly relates to a substrate on which a semiconductor light-emitting element is mounted, a light-emitting device using the semiconductor light-emitting element, and a lighting device using the semiconductor light-emitting element. Background technique [0002] In recent years, semiconductor light-emitting elements such as light-emitting diodes (LED: Light Emitting Diode) have been widely used in various devices as high-efficiency and space-saving light sources, for example, as backlight sources in liquid crystal display devices, or as It is used as a light source for lighting in lighting devices such as basic lighting and straight tube LED lamps. In this case, LEDs are unitized into LED modules and incorporated in various devices. [0003] As such an LED module, for example, Patent Document 1 discloses a COB (Chip On Board: Chip On Board) type ligh...
