Technical Field

[0001] The utility model relates to the technical field of phosphor thermal stability testing, in particular to a phosphor thermal stability testing device. Background Technique

[0002] Phosphors, commonly known as luminous powders, are usually divided into two categories: photoluminescent energy storage luminous powders and radioactive luminous powders. The photoluminescent energy storage luminous powder stores light energy after being irradiated by natural light, fluorescent light, ultraviolet light, etc. After the light irradiation stops, it slowly releases the light energy in the form of fluorescence. Therefore, it can still be seen glowing at night or in the dark, and the duration can last for several hours to more than a dozen hours.

[0003] When testing the thermal stability of phosphors, the phosphor is usually coated on a light-transmitting material, and then the temperature is increased. The thermal stability of the phosphor is obtained based on the change in the light transmittance. However, the existing phosphor thermal stability testing devices, although they can perform detection, only test a single group of phosphors and it is difficult to test multiple groups of phosphors simultaneously, resulting in a reduced scope of application of the device and a serious impact on the detection efficiency.
