[0002] Lamps are often equipped with transparent parts, so that the light emitted by the light source can be radiated through the transparent parts. However, the temperature inside the lamp is often high. When water drops onto the transparent parts, the temperature of the transparent parts that touch the water drops sharply, and the temperature is very different from that of other parts of the transparent parts, causing the transparent parts to break, thus causing damage to the lamp and causing safety accidents. Therefore, the thermal shock performance of the transparent parts of lamps is an important indicator for measuring the quality of lamps. Therefore, it is necessary to test the thermal shock performance of transparent parts, and a thermal shock tester is needed.
