4. CIRCUIT DESCRIPTION:
LED’s are soldered in Glass Epoxy PCB The LED’s are operated in a multi channel
series/parallel matrix and are multiplexed pulse operated at high frequency, high
intensity and low duty cycle to obtain maximum visible brightness at minimum POWER
consumption. The electronic circuit is built in the unit itself. With tinted lens for
protection in a sealed beam type plastic housing
With built in photo-electric switch to reduce intensity / wattage during night time -
optional. |
