Product Specs
Wireless bonded LED technology, often referred to as flip chip, offers several key performance benefits over traditional SMT (Surface Mount Technology) LEDs including enhanced durability, enhanced heat dissipation and superior light performance Flip chip LEDs provide superior light performance compared to conventional LED technology.
Higher light oulput is achieved in a more compact space and the light performance is not disrupfed by shadows or other obstacles to consistent performance.
With wireless bonded technology the chip can directly emit light from the top and the side with no wire bond casting shadows or creating uneven light distribution, providing 15% more light output.
