13. Trends da Ci gaban Masana'antu

Trend a cikin SMD LEDs yana ci gaba zuwa mafi inganci (lumens mafi yawa a kowace watt), ƙananan girman marufi, da ingantaccen aminci. Fasahar InGaN don LEDs blue da kore ta ga ci gaba mai dorewa a cikin fitarwa da tsawon rai. Har ila yau, ana ƙara ba da fifiko kan ƙarin ƙarfi na binning na launi da ƙarfi don biyan buƙatun aikace-aikace kamar nunin cikakken launi da hasken gine-gine, inda daidaito ke da mahimmanci. Bugu da ƙari, ci gaban marufi yana mai da hankali kan inganta aikin zafi don ba da damar manyan halayen tuƙi ba tare da lalata tsawon rai ba, da kuma haɓaka dacewa da atomatik ɗauka da sanya hanyoyin gyarawa don samarwa mai yawa mai tsada.

The trend in SMD LEDs continues towards higher efficiency (more lumens per watt), smaller package sizes, and improved reliability. InGaN technology for blue and green LEDs has seen steady improvements in output and longevity. There is also a growing emphasis on tighter color and intensity binning to meet the demands of applications like full-color displays and architectural lighting, where consistency is critical. Furthermore, packaging advancements focus on improving thermal performance to allow higher drive currents without compromising lifespan, and on enhancing compatibility with automated pick-and-place and reflow soldering processes for cost-effective mass production.
