The invention relates to a temperature controlling base for testing semi-conductive illuminant device, which is provided with temperature controlling function and avoids condensation of moisture. The invention comprises a temperature controlling device and a seal closure which is matched with the temperature controlling device, wherein testing specimens can be arranged into the seal closure and matched with the temperature controlling device. The distinguishing progresses of the invention are that the testing specimens is located in a comparative constant temperature status through an arrangement of the temperature controlling device, testing results are accurate, the testing specimens are separated form around circumstance through the arrangement of the seal closure, thereby effects of the around circumstance can be avoided, sealing effects of the seal closure is better through the arrangement of seal components, the arrangement of an extraction opening enables that a vacuum machine is connected with the seal closure through the extraction opening, air inside the seal closure can be extracted, vapor can be decreased, the vapor can be avoided to condense on the testing specimens.
