Embodiment Construction

[0070] Hereinafter, the substrate for a light-emitting element of the present invention and its manufacturing method will be described in detail. In addition, the light-emitting device of the present invention will be described along with this description. In addition, various elements shown in the drawings are merely schematically shown for understanding the present invention, and dimensional ratios, appearances, and the like may be different from actual ones.

[0071] [Substrate for light-emitting element of the present invention]

[0072] In the light-emitting element substrate of the present invention, a voltage-dependent resistive layer is embedded as a protective element in a region of the substrate overlapping with a mounted light-emitting element. That is, if figure 1 As shown, in the light-emitting element substrate 100 of the present invention, the voltage-dependent resistor layer 50 as a protective element is embedded in the light-emitting element mounting region...

Abstract

Disclosed is a substrate for a light emitting element, which has one of the two facing main surfaces as a mounting surface, and has the light emitting element mounted on the mounting surface. The substrate for the light emitting element is provided with a protection element for the light emitting element, said protection element including a voltage-dependent resistance layer embedded in a substrate body, and a first electrode and a second electrode connected to the voltage-dependent resistance layer. The light emitting element is mounted such that the light emitting element overlaps the voltage-dependent resistance layer.

Description

technical field [0001] The present invention relates to a substrate for a light-emitting element and a manufacturing method thereof. More specifically, the present invention relates to a substrate for a light-emitting element on which a light-emitting diode (hereinafter also referred to as "LED") is mounted, and a method for manufacturing the substrate. Furthermore, the present invention relates to a light emitting device configured by mounting a light emitting element on a light emitting element substrate. Background technique [0002] In recent years, LEDs as light sources have been used in various applications due to their advantages of energy saving and long life. In particular, recently, the luminous efficiency of LEDs has been improved in high-intensity applications, and LEDs have begun to be used in lighting applications. [0003] In lighting applications of white LEDs, the amount of light can be increased by increasing the current applied to the LEDs. However, und...
