Application example: Windowless chicken farm PLC system lighting

Even in environments where it is difficult to establish infrastructure, even in environments where existing infrastructure can not be modified, the latest system lighting can be introduced by using PLC.Since it connects everything including the network with only the power line (AC line), installation is completed with a simple laying construction.

Application example: Plant factory

As the global food crisis is anticipated, "industrialization of agriculture (plant factory)" to efficiently produce agricultural crops such as vegetables and cereals has been drawing attention.
The wavelength of the light necessary for plant growth is mainly red (640 to 680 nm) and blue (450 to 480 nm), and it is known that it is possible to control the growth rate and shape of the plant by adjusting the light amount and the irradiation time.
Recently, attempts have been made to control contained nutrients by adding light of other wavelengths in a balanced manner to this. This can be realized by taking advantage of single wavelength characteristics of LED.

LED lighting units for plant breeding research are being put into practical use that can accurately program control light balance and irradiation time in order to respond to market voices that want to specify different optimum light environmental conditions for each plant.

Fishing lamp control - Automatic control of light sources with different wavelengths

Application to fish reacting to specific wavelengths is being used for fishery fishing lamps. Depending on fish species and harvest time, it is necessary to switch delicate wavelengths, and there is a demand for automatic control.

- Case of squid fishing boat -
Since the peak emission wavelength (450 to 500 nm) of the blue light-emitting diode (LED) is almost consistent with less light attenuation in the ocean and near the maximum value (470 to 490 nm) of the visual sensitivity of the squid type , It has extremely excellent characteristics as a fish lamp light source. Furthermore, fishing lamps using blue LEDs have the following features.

(1) The power consumption is extremely low and a significant fuel oil saving effect is expected, bringing about improvement of management of squid fishing fishery management body and reduction of CO2 emission.
(2) It has a long life of more than 10 years (metal halide lamp is about 2 years), as compared with the conventional light source of glass sealing structure, the package of LED is also superior in mechanical strength so it is used for severe shipboard To endure.
(3) It has strong directivity and can irradiate 90% or more of light flux into water. (In the metal halide lamp which is the point light source, about 80% is scattered in the air)
(4) Since stabilizers used for controlling metal halide lamps and auxiliary power generators with large output are unnecessary, it is expected to greatly reduce equipment costs and increase space inside the ship.
(5) There is no influence on the health of the fishery by ultraviolet radiation and the influence on the environment due to light damage.
