It is non-ideal for directional applications and has poorer heat sinking due to the use of transparent glue. The wire bond complicates phosphor integration; (b)

Advantages include high luminance light source for directional applications and an excellent heat sinking for HP applications. Nonetheless, the thin-film structure requires careful handling, and the wire-bond complicates phosphor integration.

luminaires will be increasingly manufactured locally due to their complexity and customized features. FINDING: The domestic manufacturing of LED lamps Luminaire product categories include the following: and lamp-based luminaires is financially unattractive, as evidenced by U.S.-based manufacturers having either • Base grade -- products which meet limited specificadivested themselves of these product lines or segregated tions -- often referred to as "consumer grade"; them operationally.

. While The capability of unique OLED products remains intriguing the adoption of tandem structures is essential to achieving because, unlike LEDs that are a directional point source, high brightness and long lifetime in OLED-SSL products, it the OLED is a diffuse-area light source distinguished by also incurs extra cost in manufacturing due to the increased its spectral quality.
