LIGHT-EMITTING DEVICE HAVING A PLURALITY OF CONCENTRIC LIGHT TRANSMITTING AREAS

摘要

The light-emitting device of the present invention includes LED chips provided on a ceramic substrate and a sealing material in which the LED chips are embedded. The sealing material contains a fluorescent substance and divided into a first fluorescent-substance-containing resin layer and a second fluorescent-substance-containing resin layer by a first resin ring and a second resin ring.

主权项

1. A light-emitting device comprising:
a plurality of light-emitting elements and a patterned electrode wire provided on a substrate; a sealing material in which the plurality of light-emitting elements are embedded; and a pair of electrode lands for supplying electricity to the plurality of light-emitting elements, the pair of electrode lands being connected to the patterned electrode wire, wherein: some of the plurality of light-emitting elements are electrically connected to the patterned electrode wire, the substrate has an unsealed area which is not sealed with the sealing material, the unsealed area being wider at corners of the substrate, the pair of electrode lands is provided in the unsealed area at the corners of the substrate so as to face each other with respect to a light-emitting element area in which the plurality of light-emitting elements are provided, and the sealing material is divided into a plurality of areas by a partition wall.
