A light-emitting diode (LED) emits light when its semiconductor draws electric current. The LED converts electric energy directly into optical energy, responding quickly and making possible pulsed lighting. The size of LED' is generally approx. 3 - 5 mm. An LED light comprises several individual LED, allowing for more flexibility in the development of lights with more varied shapes and sizes than conventional lights.

These are the main features of LED lighting.
CS creates Lighting Systems that take full advantage of the features of LEDs.

Single Wavelength An LED has a narrow light emission spectral band and can be designed to radiate single-wavelength light through the selection of the element. High Efficiency The wavelengths of some LED are compatible with the absorption peak of the pigments involved in photosynthesis and photomorphogenesis. Only necessary light for those physiological functions can be irradiated. Low Thermal Irradiation LED in the visible light area contain little heat rays, allowing for short-distance irradiation. Pulsed Emission Pulsed emission would elongate its service life rather than contagiously emitting. In addition, pulsed irradiation improves the efficiency of photosynthesis. Reduced Energy Consumption and Long Life LED substantially reduce power consumption. Depending on the operating environment, an LED can provide thousands of hours of light.

Since an LED emits light through a semiconductor device, its life is many times longer than that of other light sources (however, it can be affected by the operating environment). Pulsed emission and heat radiation measures can extend the life of an LED light.
