Light-emitting device and method of manufacturing the same
摘要
說明書
The base member 2 may include, on a lower surface thereof, a heat dissipation terminal electrically independent of the light-emitting element 1. It is preferable that the heat dissipation terminal have an area larger than the sum of the areas of the upper surfaces of all light-emitting elements 1 included in the light-emitting device 100, and that the heat dissipation terminal overlap the region directly under the light-emitting elements 1. This structure of the heat dissipation terminal allows the light-emitting device 100 to have better heat dissipation performance. The color of the base member 2 may be white, which allows for obtaining good light extraction efficiency, but at least a portion of the upper surface of the package preferably has a dark color such as black, in order to reduce the reflectance of extraneous light, and may have irregularities to scatter extraneous light. The inner walls of the recess 2a may be in a dark color to enhance the display contrast, or the inner walls of the recess 2a may be white to enhance the light extraction efficiency.
