What is the LED?

LED Structure

LED Features

Light Emitting Diode

Very Long Life span

Environmental friendly with no Mercury

High Light Emitting Efficiency
: Incandescent 8% vs. LED 30%

70- 80% Utility Bill Savings

Two wave lengths : Blue, Yellow

No IR & UV

Advantages of LED : CRI (Color Rendering index)

The higher the CRI, the solar light emits colors similar to the Natural Color Outstanding differences in between CRI and HPS (High Pressure Sodium) Lamp is that CRI is around 30Ra and LED Lamp is over 70Ra. LED lights with high CRI enables as a Security Illumination, which makes it possible to identify people or things recorded on Security Camera installed in a dark and deserted street especially in the crime-ridden district. It is also possible to make it easy to recognize the information recorded on the speed camera or other surveillance equipment installed on a highway.

***CRI is used to measure how accurately a lighting source renders the color of objects when compared to sunlight. Sunlight is defined to have a CRI of 100, while white fluorescent lamps have CRI varying from the 50s to 98

Advantages of LED : Enormous Energy Saving in Fishing Vessel

High-efficient LED lamp enables energy saving: >>More than 3 X of oil cost saving(Genset)

Compared to conventional Fishing lamps, lights at 470~480nm of wavelength sensitively attracts fishes to react and flock to it.

LED lights which does not contain UV and IR, keep fishes fresh for a longer time.
