Title:
TRANSMISSIVE TEMPERATURE-CONTROLLABLE LASER-EXCITED REMOTE PHOSPHOR MATERIAL TESTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/057032
Kind Code:
A1
Abstract:
A transmissive temperature-controllable laser-excited remote phosphor material testing device realizing laser-excited remote phosphor material testing comprising: a first integrating sphere (1), a second integrating sphere (2), a third integrating sphere (3), a temperature control platform (4), a first sliding rail (5), a second sliding rail (6), an optical platform (7), a laser diode (8), a first sliding block (9), a second sliding block (6), a third sliding block (11), a first spectrometer (12), a second spectrometer (13), a third spectrometer (14), and a drive power supply (15). The first integrating sphere (1) is installed on the third sliding block (11) and is slidably fitted to the first sliding rail (5) and the second sliding rail (6) via the third sliding block (11). The second integrating sphere (2) is installed on the second sliding block (10) and is slidably fitted to the first sliding rail (5) and the second sliding rail (6) via the second sliding block (10). The third integrating sphere (3) is installed on the first sliding block (9) and is slidably fitted to the first sliding rail (5) and the second sliding rail (5) via the first sliding block (9). The laser diode (8) is placed next to the first integrating sphere (1). A light beam emitted by the laser diode (8) irradiates, via the first integrating sphere (1), the temperature control platform (4) on which a phosphor material is placed.
