Flip-chip light emitting diode with high light-emitting efficiency
Flip-chip light emitting diode with high light-emitting efficiency A flip-chip light emitting diode with high light-emitting efficiency is disclosed. The LED includes a transparent conductive layer, an oxide layer, a reflective metal layer, a conductive layer, and a protective diffusion layer sequentially disposed over a p-type semiconductor layer. Thereby, light emitting from a light-emitting layer toward the p-type semiconductor layer is reflected and penetrating a transparent substrate and emitting outwards. Thus the problem of light shielded from the flip-chip type LED is solved and the light-emitting efficiency is improved. Furthermore, the present invention disposes the LED chip in a face-down orientation on a conductive substrate by flip-chip technology so as to enhance heat-dissipation efficiency of the LED.

External extraction light emitting diode based upon crystallographic faceted surfaces
External extraction light emitting diode based upon crystallographic faceted surfaces A light emitting diode is disclosed that includes a support structure and a Group III nitride light emitting active structure mesa on the support structure. The mesa has its sidewalls along an indexed crystal plane of the Group III nitride. A method of forming the diode is also disclosed that includes the steps of removing a substrate from a Group III nitride light emitting structure that includes a sub-mount structure on the Group III nitride light emitting structure opposite the substrate, and thereafter etching the surface of the Group III nitride from which the substrate has been removed with an anisotropic etch to develop crystal facets on the surface in which the facets are along an index plane of the Group III nitride. The method can also include etching the light emitting structure with an anisotropic etch to form a mesa with edges along an index plane of the Group III nitride. Read more »

Diode Lighting System
Diode Lighting System A lighting system for stage, theatrical and architectural lighting, comprising a frame for supporting a plurality of light emitting diodes. The diodes are mounted to the frame so that each diode is both secured to the frame and also simultaneously positioned wherein each discrete diode light beam is directed to a prescribed remote focal point (target zone) and thereupon directed to a predetermined illumination area. Electrical power for transmitting and controlling electrical voltage to light emitting diodes by electrical circuitry integral with the frame. The frame can be configured as any hollow volume such a cone, a semi-ellipse, and a semi-sphere or can be configured as planar. Flexible blanks having apertures and pads for electrical connections can be used to construct rigid frames. An imaging gate a collimating lens and a focusing lens can be interposed between the frame and the illumination area. The frame can also be a sandwich frame having positive and negative electrically conductive layers interposed between layers of biasable insulating foam. Read more »
