Abstract

A light-emitting device, comprising: a first translucent supporting base, comprising a first translucent insulator and a conductive circuit layer provided on the surface of the first translucent insulator; a second translucent supporting base, comprising The second light-transmitting insulator is arranged with a predetermined gap between the first light-transmitting support base and the surface of the second light-transmitting insulator facing the conductive circuit layer; and the light-emitting diode, It has a diode body and first and second electrodes. The first and second electrodes are arranged on one surface of the diode body and are electrically connected to the conductive circuit layer through conductive protrusions. The light emitting diode is arranged on the The gap between the first translucent supporting base and the second translucent supporting base; and a third translucent insulator embedded in the first translucent supporting base and the second translucent supporting base. space between the supporting substrates.

Description

technical field [0001] Embodiments of the present invention relate to light emitting devices and methods of manufacturing the same. Background technique [0002] Light-emitting devices using light-emitting diodes (LEDs) are widely used in optical devices such as indoor, outdoor, fixed installation, and mobile display devices, display lamps, various switches, signal devices, and general lighting. Among light-emitting devices using LEDs, a transparent light-emitting device in which a plurality of LEDs are arranged between two transparent substrates is known as a suitable device for displaying various character strings, geometric figures, patterns, etc., and display lamps. . [0003] Using a transparent resin-made flexible substrate or the like as the transparent substrate reduces constraints on the mounting surface of a light-emitting device such as a display device or a display lamp, thereby improving the convenience and usability of the transparent light-emitting device. ...
