Philips Lumileds today announced that its LUXEON Rebel LEDs are recognized by Underwriters Laboratories (UL), and have become the first high power DC LEDs to earn UL Recognized certification. The recognition will speed time to market by making it possible to obtain UL Listed status for New luminaires built with LUXEON Rebel without requiring a full insystem LED component investigation. The certification will also facilitate ENERGY STAR acceptance, since luminaires must be UL Listed in order to be eligible for the ENERGY STAR label.
In addition, being UL Recognized will help bring increased efficiency to LED applications, such as street lights, by facilitating the use of Class 1 power supplies. The LUXEON Rebel lens meets the requirements to be considered an electrical enclosure under UL standards, eliminate the need For a full UL investigation that in the past has discouraged the use of more efficient Class 1 power sources.
Flex-Rigid PCB, it's the PCB that part of it is rigid and part of it is flex. It combine flex PCB and rigid PCB in a same PCB together and we call it flex-rigid PCB or rigid-flex PCB. Normally, the rigid PCB area is for soldering electronic components and the flex PCB area would be taken as cables to connect rigid PCB areas together, this could make the rigid-flex PCB perfectly suit for a wide range of applications.
PCB = printed circuit board and PCBA = printed circuit board assembly. For PCB, it means the copper circuits be printed on a board, and so the main composition of PCB are copper and board.
The copper is the circuits material and the circuits designed by the PCB designers. Depends on the current in the circuits, the PCB copper thickness could be done with 0.5oz-10oz. But the PCB designers need be noted that the copper track width/space need be enlarged with the thickness. For example, the minimum copper track width/space could be 3mil/3mil with 0.5oz, but would be 4mil/4mil with 1oz.
The PCB board could be rigid PCB, could be flex PCB and also could be flex-rigid PCB. And the materials could be FR4, PI, Aluminum, Copper-based, Rogers, Teflon, etc. They have different applications. For example, FR4 PCB is the most commonly used for rigid PCB and almost good for all electronics products; PI is the most commonly used for flex PCB; Aluminum and copper-based have good thermal diffusivity and always used for LED PCB ; Rogers PCB and Teflon PCB are always used for High Frequency PCB, etc.
