Light emitting device and method for manufacturing the same
View Patent ↗By using a light emitting device including an insulating substrate and a light emitting unit formed on the insulating substrate, the light emitting unit including: a plurality of linear wiring patterns disposed on the insulating substrate in parallel with one another, a plurality of light emitting elements that are mounted between the wiring patterns while being electrically connected to the wiring patterns, and a sealing member for sealing the light emitting elements, as well as a method for manufacturing thereof, it becomes possible to provide a light emitting device that achieves sufficient electrical insulation and has simple manufacturing processes so that it can be manufactured at a low cost, and a method for manufacturing the same.
1. One of a backlight light source of a liquid crystal display and a light source for illumination, comprising:
a light emitting device; and
a matching member,
wherein the light emitting device comprises a substrate, and a light emitting unit comprising a light emitting element mounted on the substrate and comprising a resin seal covering the light emitting element,
on the substrate, there is a peripheral area free of the resin seal and completely surrounding the light emitting unit in plan view of the substrate,
in the peripheral area, there are a positive electrode externally connecting land, a negative electrode externally connecting land, and one of a through hole penetrating the substrate and a hole having a cut-out shape and penetrating the substrate, and
the light emitting device is secured to the matching member with one of a screw and a jig inserted into said one of the through hole and the hole having the cut-out shape.
2. The light source for illumination of claim 1 , comprising one of a light bulb-type LED lamp and a fluorescent lighting-type LED lamp.
3. The one of a backlight light source of a liquid crystal display and a light source for illumination of claim 1 , wherein the light emitting unit comprises a plurality of light emitting elements mounted on the substrate, all of the light emitting elements are sealed by the resin seal, and the positive electrode externally connecting land is opposite to the negative electrode externally connecting land with respect to the light emitting unit disposed therebetween.
4. The one of a backlight light source of a liquid crystal display and a light source for illumination of claim 1 , wherein, in the peripheral area, there is another of the through hole penetrating the substrate and the hole having a cut-out shape and penetrating the substrate, and said one of the through hole and the hole having the cut-out shape is opposite to the said another of the through hole and the hole having the cut-out shape with respect to the light emitting unit disposed therebetween.
