The invention discloses a light-emitting diode illuminating equipment including an illuminating apparatus and a replaceable shell. The replaceable shell is detachable to be engaged to the illuminating apparatus. The illuminating apparatus includes a heat-dissipating plate device, a plurality of diode light-emitting devices, a plurality of heat-conducting devices, and a hollow barrel. The hollow barrel is engaged to the heat-dissipating plate device to form a space for accommodating the diode light-emitting devices and the heat-conducting devices. Depending on different product designs, the replaceable shell is variously detachable to be engaged to the heat-dissipating plate device or the hollow barrel. Therefore, the appearance of the light-emitting diode illuminating equipment of the invention is beautified by the appearance design of the replaceable shell.
