It is known from experiments that the moisture absorption rate of the lamp desiccant exhibits different moisture absorption rates depending on the ambient temperature and humidity, and the physical state of the contents is also different. In the indoor environment, the maximum moisture absorption rate is 88.82%, which is gel solid state; in the constant temperature and humidity chamber (40 ° C, 90% RH), the maximum moisture absorption rate is 210.31%, and the content is a flowing liquid state. In an indoor environment, the lamp is not completely sealed, and the desiccant in the lamp becomes longer as the hygroscopic rate increases over time. The relative humidity in the lamp in the constant temperature and humidity chamber (40 ° C, 90% RH) has been increasing, indicating that the effect of the desiccant is weakening.
