Conference will include LED technology and standards updates
Maury Wright previews conference sessions and projects that a lively debate will take place on LED component trends, and that standards and regulatory discussions will prove very informative to SSL industry players.

Matching SSL and control technology remains a challenge
Ethan Biery explores the state of the industry for LED dimming and control and recommends the paths for success to lighting specifiers.

Standards emerge specifically for SSL test methods
European standards, driven primarily by the IEC, increasingly address safety and performance issues that are specific to LED-based lighting, explains Pasi Orrevetelainen.

COB LEDs simplify SSL manufacturing, drive broader deployment
Dense LED arrays can reduce the design complexity and manufacturing cost of solid-state lighting products and ultimately help solve the global energy crisis, writes Ron Weber.

LEDs light the road ahead in automotive applications
Morand Fachot explains that international standards and evolving LED technology are set to play a key role in the widespread transition to solid-state lighting in automotive applications.

Improve LED manufacturing via in-line monitoring and SPC
In-line monitoring of defects on LED wafers allows manufacturers to understand which defects impact yield and to apply that information in a constant effort to improve yield, explains Steven Chen.

Dimming multiple LED strings enables color-tunable luminaires
David Zhang explains that you can use analog dimming, PWM dimming, or a mix of the two to achieve color-mixing SSL products with the application dictating the best choice.

Myth busting as it relates to LED tubes
Charlie Szoradi, CEO of Independence LED, states that it's only a question of when the time is right to install LED tubes in place of fluorescents and not if it's the right retrofit path.
