The invention provides a light-emitting diode illuminating equipment. The light-emitting diode illuminating equipment of the invention includes a heat-dissipating plate device, a plurality of heat-dissipating fins, a diode light-emitting apparatus, a plurality of heat-conducting devices, and a shield device. The heat-dissipating fins extend from a surface of the heat-dissipating plate device. By tightly mounting the heat-conducting devices on the surface of the heat-dissipating plate device and disposing between the heat-dissipating fins, heat generated during the operation of the diode light-emitting apparatus is distributed uniformly on the heat-dissipating plate device and the heat-dissipating fins due to the high efficiency heat-conducting of the heat-conducting devices, and then is dissipated. Besides, the shield device has a waterproof passage for a power cord passing through to power a control circuit, such that the light-emitting diode illuminating equipment is adapted to be installed outdoors.
