Cree adds high-current COB LEDs based on a metal substrate
Cree has announced the XLamp CMA family of chip-on-board (COB) LEDs that mark the company’s first foray into such LEDs manufactured on an aluminum substrate as opposed to a ceramic substrate. Cree is informally calling the new line a high-current family and positioning the portfolio to fit between the Standard Density and High Density ceramic-based LEDs announced previously. The type of substrate used in COB LEDs has not been a mainstream issue, although LED makers and some solid-state lighting (SSL) product developers have strong feelings on the topic.
