Greater brightness, life span on flexible LED strips R&D agenda

摘要

Manufacturers of flexible LED strips in China aim for higher brightness and longer life span to boost competitiveness and take better advantage of accelerating adoption in outdoor and indoor lighting. They hope to increase the use of SMD diodes with individual luminous flux of more than 20 lumens. Although companies offer models with up to 24-lumen LEDs, most releases utilize those in 10 to 14 lumens. To prolong product life span, companies are considering radiation in lieu of the conventional conduction thermal management technique. The former method entails applying radiation coating on the substrate to replace the silica gel pad for enhanced heat dissipation, which impacts diode operating life. The maximum that can be reached in the local selection based on conduction is 100,000 hours.
