13. Trends na Masana'antu da Ci gaba

The trend in SMD LEDs continues towards miniaturization, higher efficiency, and greater reliability. Package heights are decreasing to enable thinner end products. Efficiency improvements (more lumens per watt) reduce power consumption and heat generation. There is also a focus on tighter binning tolerances and improved color consistency across production batches. Furthermore, compatibility with automated assembly processes and high-temperature, lead-free soldering profiles remains a fundamental requirement for broad market adoption in global electronics manufacturing.
