Abstract
An LED diaphragm structure includes an insulation base, a plurality of frames, and a plurality of LED chips, wherein the insulation base includes an upper surface on which a plurality of receiving recesses are provided. The plural frames include a plurality of positive-pole frames and a negative-pole frame, where the positive-pole frames do not contact with the negative-pole frame. The plural frames and the insulation base are formed together as an integral structure. The plural LED chips are correspondingly disposed in the plural receiving recesses of the insulation base, where each LED chip has its positive-pole terminal and negative-pole terminal electrically connected with contact portions of the plural positive-pole frames and of the negative-pole frame, respectively. Accordingly, the plural frames are combined with the insulation base as an integral structure, such that the LED diaphragm structure so assembled can be lightweight and compact.
