Introduction
Interpretation of the LED Screening Specifications for Space Science Lighting
| Screening Items | Screening Methods | Qualified Criteria | Remarks |
|---|---|---|---|
| Appearance Inspection | Inspect with a 10x magnifying glass at room temperature. There shall be no defects such as rust, cracks, bubbles, etc. | - No physical damage- Clear markings | Applicable to all devices |
| Constant Acceleration Test | 196000m/s², for 1 minute. | - No functional failure- No obvious change in appearance | Ensure mechanical vibration resistance |
| High temperature storage test | 110℃±2℃, for 48 hours. | - Parameter change rate ≤5% - No physical damage | Verify high temperature environment adaptability |
| Temperature cycle test | High temperature 65℃±2℃, low temperature -40℃±2℃, 5 cycles. | - Parameter change rate ≤5% - No functional failure | Simulation of extreme temperature change environment |
Actual application case: LED screening process for a space science project
In a space science project, the GB/T32872-2016 standard was used for LED screening. Through strict appearance inspection and high-temperature storage tests, 15% of unqualified products were eliminated. Subsequently, in constant acceleration and temperature cycle tests, 5% of products were further eliminated. In the end, only 90% of the devices passed all tests and met the lighting needs of space science.
Implementation suggestions
- Establish a complete screening process:Screen strictly according to the items and sequence specified in the standard, and ensure that detailed data is recorded at each step.
- Optimize test equipment:Use high-precision test instruments to ensure the accuracy and consistency of parameter measurement.
- Strengthen quality traceability:Establish a unique number for each device to facilitate tracking and analysis of quality issues.
- Regular standard updates:Revise screening standards in a timely manner according to technological development and project needs to ensure their applicability.
