LED Blankout & FRAMELITE Traffic Control Signs.
LED Viewing Angles and Perception
FrameLite Signs use SMD5050 LED's. These LED's provide a 120 degree viewing angle. These are fine in most circumstances. With a wide angle LED you are able to view the sign from the side at a close distance. The drawback is that from a distance and especially in bright sunlight you may not be able to see the LED flash. Please take into consideration that YELLOW color LED's are the most difficult to see in bright sunlight.
For increased visibility at a distance, a 30 degree LED would be a better choice. However these can be overwhelming to night time drivers in dark locations where there is very little ambient lighting. This must be considered when specifying the type of LED in the FrameLite sign.
M-Systems Inc now offers FrameLite signs using CREE 30 deg high brightness led's in YELLOW or RED. These must be requested when ordering.
