PCB prototype manufacturing: LED traffic signal display PCB assembly
Detail Information
LEDs have already replaced traditional incandescent lamps in traffic signal applications for their high efficiency, low power consumption and long life. LED Traffic Signals use both high brightness & high power LEDs connected in a combination of series and parallel to build a LED cluster. To realize specific luminous distribution intensity, an additional optical design (lenses) is necessary. If traffic signals are driven by AC power, an AC-DC circuit is required to convert AC to DC power that is suited for LED driver to drive LED cluster/string. MCU is used to implement the control over LED driver so as to give correct traffic signals.
Features of Traffic Signal:
Minimum maintenance
Low power consumption
Compatible with standard signal heads
Optimal visibility
Even distribution of luminosity
High intensity light
