Description:

1. The visual requirements of signs set the viewing angle of the LEDs. Signs installed on highways, for example, require bright LEDs with a narrow beam width, but in cities with a requirement for short distance legibility a wide beam width LED is usually required.

2. Outdoor message signs must typically operate for over ten years in a harsh, corrosive, and exposed working environment. Dicolor LED traffic sign use new 15 and 30 degree viewing angle lamps. The maximum LED junction temperature limit of +130 enables high temperature operation in bright sunlight conditions. The lamp epoxy uses UV inhibitors to reduce the effects of long term exposure to direct sunlight.

Applications:

road & bridge construction

Competitive Advantage:

Variable message signs, or VMS, have been the key elements for dynamic traffic management. It ensures that the traffic situation, regardless o roadways and condition, can be controlled and maintained. Depending in a certain situation, these variable displays are designed to warn, inform, and guide motorists on the expressways and highways. For variable message signs manufacturers, it is very important to improve the technology of signal display to perfection with their own developments and following the set of standards with respect to LED-based variable message signs.
