Underwater lamps, such as deep sea lighting lamps, all require underwater deep pressure resistance tests. In the prior art, the lamps and lanterns all adopt watertight joints that waterproof performance is better, ensure good withstand voltage under water. However, due to the sufficient tightness of the joint, the temperature rise probe cannot be extended into the lamp to perform temperature rise test at the LED chip. Therefore, an additional through hole joint is needed to be added when the temperature rise test is performed, the temperature rise wire is penetrated into the cable, and then the temperature rise test at the LED chip is performed through the through hole joint.
In the prior art, one hole site is used for installing a pressure-resistant test related sensor, and the other hole site is used for installing a temperature-rise test related sensor in the underwater temperature-rise test. The two holes are different in pore size and therefore cannot be compatible for universal use.
The difficulty of sealing the two hole sites is high, and particularly when the lamp performs underwater pressure-resistant test, the lamp is required to bear certain pressure on one hand, and the sealing success rate of the test hole is affected; on the other hand, the device is placed under water to a deeper depth, and long time is consumed for retrieval and cleaning after failure operation is carried out. Assuming that the sealing success rate using the single-hole test is 70%, the sealing success rate using the double-hole test is only 70% by 70% =49%, the success rate of the test is greatly affected and the test cost is increased from the probability.
