Inclined Light Emitting Element With Spherical Terminals

The patent employs spherical terminals instead of conventional planar electrode structures. The spherical shape naturally accommodates the inclined light emission surface while simplifying the connection interface. The sphere can be easily positioned and bonded to the curved or inclined surfaces without requiring complex alignment mechanisms, thus resolving the contradiction between improved light emission efficiency and reduced terminal formation complexity.

The spherical terminal geometry provides inherent alignment tolerance. When bonding the spherical terminal to the light emitting element, the curved surfaces can accommodate slight angular deviations without compromising electrical connection quality. This eliminates the need for high-precision alignment during manufacturing while maintaining the beneficial inclined light emission directionality.

The spherical terminal design concentrates the electrical connection function at the local contact point or small contact area between the sphere and the bonding interface. While the overall spherical surface area is limited, the local quality of the contact region is optimized through controlled bonding processes that ensure low-resistance electrical connection. This local optimization compensates for the reduced total surface area while maintaining ease of connection benefits.
