Scope

Scope: This document specifies the spectral performance, colorimetric coordinates, saturation threshold, illuminance instability, and beam width performance indicators and measurement methods for rare earth fluorescent ceramics used in laser lighting. This document is applicable to the evaluation and measurement of the optical performance of rare earth fluorescent ceramics used in laser lighting. Main technical contents: Laser lighting sources based on laser diode (LD) technology. 3.2 Laser fluorescent ceramics are inorganic ceramic materials that can emit light when excited by light emitted from a laser diode (LD). 3.3 Saturation threshold is the laser power density value corresponding to the peak luminous flux obtained by the fluorescent material under laser radiation. 3.4 Light collimators are optical components that convert the light emitted from an LD source into collimated light (parallel light). 3.5 Illuminance instability is the degree of change in the illuminance value at a certain point of the output light of the fluorescent material within a certain time range. 4. Requirements 4.1 Test conditions 4.1.1 Environmental requirements: The environment during measurement should meet the following requirements: a) Temperature: 20℃～25℃; b) Relative humidity: <65%; c) No obvious vibration, airflow, smoke, stray light, or electromagnetic interference; d) Environmental illuminance: In a darker environment, avoid strong light interference; e) Anti-static measures. 4.1.2 Safety requirements: a) Laser safety protection measures should be taken in accordance with the requirements of GB 7247.1 during measurement; b) The electrical system of the laser should comply with the provisions of GB/T 10320. 4.2 Requirements for the fluorescent ceramic samples under test Except for special requirements, the samples should meet the following requirements: a) The parallelism of the two end faces (plane/plane) should not exceed 30"; b) The vertica
