PC LED Lighting Applications
Problem Phenomenon
[Problem Phenomenon] LED lenses and lamp covers require high light transmission and heat resistance
Cause Analysis
PC with high light transmission and heat resistance is used for LED lenses, light guide plates and lamp covers; optical-grade grades guarantee light efficiency; heat resistance adapts to LED temperature rise; when troubleshooting on site, verify each item according to this mechanism one by one, and avoid blindly adjusting the machine based on experience alone
Solution
Select optical-grade PC for LED lenses; select diffusion or transparent grades for lamp covers; heat resistance verification; after adjustment, take samples continuously to verify the effect, and resume mass production only after confirming stability; change only one variable at a time and record parameter changes, so as to locate effective measures
Key Takeaway
PC LED lenses have high light transmission and heat resistance, and are the main force in lighting; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future
