LED beads are an efficient and environmentally friendly lighting source widely used in various fields. Effective testing is crucial to ensure the quality and performance of LED beads. The following are common testing methods for LED lamp beads: 1 Electrical parameter testing: This is one of the most basic testing methods for LED beads. By measuring electrical parameters such as voltage, current, and power of LED beads, their electrical performance and efficiency can be evaluated. 2. Light parameter test: This test is used to measure the light output performance of LED beads. Common light parameters include luminous flux, illuminance, light intensity, and light color. Light parameter testing can help understand the lighting performance and optical characteristics of LED beads.

3. Color temperature and color coordinate test: This test is used to determine the color temperature and color coordinates of LED lamp beads. Color temperature refers to the degree to which the color of light is warm or cold, while color coordinates are used to describe the position of the color of light in the color space.

4. Color consistency test: The color consistency of LED beads is crucial for lighting applications. By testing the color of multiple LED beads, it can be ensured that they have consistent color characteristics in the same batch.

5. Thermal performance test: LED beads generate heat during operation, and thermal performance test is used to evaluate the heat dissipation effect and temperature characteristics of LED beads. Good thermal performance helps to extend the lifespan of LED beads and improve their reliability.

6. Reliability test: This test is used to simulate the working condition of LED beads during long-term use. Common reliability tests include life testing, temperature cycling testing, and damp heat testing to ensure that LED beads can operate stably in various environments.

7. Pulse testing: Pulse testing is used to evaluate the response speed and spectral characteristics of LED beads. By activating LED beads with brief high-frequency pulses, one can understand their performance under rapid switching states.
