Product Description:

Ultra-high brightness light-emitting diode chips AlInGaP and InGaN as a light source, low power consumption, long life of the product, to maintain a reasonable cost products.

Special circuit design, even if the individual LED damage does not affect the normal operation of other LED's, uniform optical distribution.

Using 110-250V constant voltage constant current power supply, wide voltage range.

Incandescent light emitting diode comparison signal lights can save 7-9 times more energy.

Match the existing traffic control logic, light box structure, easy installation.

Features:

High efficiency, long life;

Ultra-thin design, PC material, lightweight;

Novel structure, beautiful appearance;

Moisture, dust; high sealing performance, good waterproof effect;

High temperature resistance, vibration, low power consumption;

Benefits:

High quality imported 14 microns four elements LED wafer fabrication;

Voltage constant current switching power supply and LED load current balancing circuit design;

AC or DC 90V-250V wide operating voltage range

To prevent the leakage current causes the error display signal circuit design;

Internal surge protection impact of the high efficiency, low temperature rise of the quick start power supply;
