Abstract
This invention is about a reliable light-emitting system and a method to make it. The light-emitting system is mounted on a carrier with a non-conductive adhesive such that at least one of the p-contact layer and n-contact layer of the light-emitting device is in direct contact with conductive patterns formed on the carrier.
Claims22
A light-emitting system comprising:
- at least one light-emitting device, said at least one light-emitting device comprising a p-doped region, an n-doped region, an active region disposed between said p-doped region and n-doped region, an n-contact layer disposed on the n-doped layer and a p-contact layer disposed on the p-doped layer;
- a carrier with conductive patterns disposed thereon forming a circuit for connecting to a power source for operating said at least one light-emitting device, said formed circuit being in electrical communication with the n-contact layer and p-contact layer of the light-emitting device;
- said at least one light-emitting device is mounted on said carrier with a non-conductive adhesive disposed on said carrier such that at least one of the p-contact layer and n-contact layer of the light-emitting device is in direct contact with said conductive patterns formed on said carrier;
- wherein said non-conductive adhesive is disposed on the carrier in the form of at least two discrete patches on the perimeter of the light-emitting device;
- wherein each of said discrete patches is at least one of a substantially spherical shape and a cuboid shape;
- and
- wherein said at least one light-emitting device is selected from the group consisting of light-emitting diode, surface mount device (SMD) package incorporating at least one light-emitting diode, integrated circuit incorporating at least one light-emitting diode, or a combination thereof.
