[Prior Art] The conventional RGB light-mixing light-emitting diodes generally include: a plurality of light-emitting chips which can generate light of the same wavelength, and a plurality of bracket units which are electrically connected to the corresponding light-emitting wafers, respectively. Each of the bracket units has two conductive supports made of a metal material. One of the conductive supports is fixed for the corresponding light-emitting chip; and the heat energy generated by the light-emitting chip can be conducted and vented in the air. However, since such a light-emitting diode generates a large amount of heat energy when used for a long period of time, if most of the heat energy cannot be effectively and efficiently discharged at this time, the light-emitting crystal chip is liable to lower its luminous efficiency due to overheating. Therefore, it is a problem to be solved by how to effectively dissipate heat to maintain the luminous efficiency of a seven-light wafer. [New content] It is to provide a light-emitting diode structure which is effective for heat dissipation.
