Title: Light-emitting diode and light-emitting diode array lamp using it
Inventor: LEE SONG-JAE
IPC: H01L33/10
Filed: 1998-05-12
Abstract: PROBLEM TO BE SOLVED: To increase an external quantum efficiency and to retain a high emission brightness regardless of a low current, by forming, in a triangular prism shape, a drum body with a number of wall surfaces, an upper surface, and a bottom surface where photons being emitted from an active region pass. SOLUTION: A chip 100 is formed in a triangular prism shape, an active region 200 is provided at the middle portion of the chip 100, and crystal layers 300 and 400 are provided above and below it. Then, electrodes 500 and 600 for supplying current to the active region 200 are formed at the crystal layers 300 and 400 on than upper and a lower surfaces of the chip 100. In the chip 100 with this kind of triangular sectional structure, photons that advance side by side with an active layer flat surface pass through one or more total reflection processes. However, the incident angle of the photons gradually changes and hence the photons can enter an escape region finally. Therefore, most photons have a chance for escaping toward the outside of the chip 100, thus improving external quantum efficiency.

Abstract: PURPOSE:To easily attain the complicated deformation by evolving the surface of a three-dimensional object into a two-dimensional form, securing the correspondence between a point on the surface of the three-dimensional object and a point in a two-di mensional parameter space, and setting a control point in the parameter space to input the moved variable of the control point. CONSTITUTION:The surface 101 of a three-dimensional object is evolved into a two-di mensional form, and a point on the surface 101 is expressed by a position on a plane obtained by the evolution. This plane is defined as a two-dimensional parameter space. A control point 105 is set on the parameter space and the moved variable of the point 105 is inputted. This input point 105 is connected to another point via a Delaunay's net 102 which is used in the algebraic geometry to secure the connection between the points adjacent to each other. The moved variable of a point included in a triangular area 104 of the net 102 is obtained by applying the linear interpolation to the moved variable of the point 105 serving as an apex of the triangle. Then the point set on the surface 101 is moved based on the moved variable of the point set in the two-dimensional parameter space, and the shape of the surface 101 is deformed. Thus the desired result of deformation is obtained.
