CHIP DESIGN
High-voltage LEDs for indoor retrofit lamps
High-voltage (HV) LEDs have a turn-on voltage that is closer to the mains supply than conventional high-current LEDs. This eliminates components, notably the driver, and offers other advantages, as Epistar’s ALEXANDER WANG explains.
RUSSIA
Russia launches LED industry association
The LED lighting industry in Russia is becoming more mature as the country seeks to develop a vertically-integrated manufacturing infrastructure. LEDs Magazine spoke with EUGENE DOLIN, the CEO of a newly-formed LED industry association in Russia.
ENERGY STAR
Navigating the Energy Star maze
UL’s Matthew Sallee answers pressing questions on energy efficiency and Energy Star certification that lighting manufacturers must understand to bring products to market successfully.
STANDARDS
LED safety standard UL 8750 requires clarity
There is still some clarity needed in how UL 8750 addresses safety requirements for packaged LED components, which can even affect the choice of encapsulation materials, writes JIANZHONG JIAO.
LED FABRICATION
Manufacturing software is key as volumes grow
As LED demand grows rapidly, automation software and process control can get more from current manufacturing lines, and this can be as important as getting new lines up and running quickly, as PHIL WALKER explains.
COMPATIBILITY
Part 5: Who shares the responsibility for testing?
Part 5 of PHILIP KEEBLER’s series on compatibility explains that LED lighting manufacturers share responsibility for implementing robust products that can withstand disturbances and work in a compatible manner with the nuances of the power grid.
