CO-GENERATIVE SPECTRAL LIGHTING DEVICE FOR HEATING OF GREENHOUSE CONVOLVULUS

摘要

The invention refers to agriculture and mainly can be used for complex local electrical heating of greenhouse convolvulus (cucumbers, tomatoes etc.) and spectral lighting. The aim is to improve device's constructive performance, to increase efficiency, to decrease prime-cost, to increase exploitation safety, and to gain economy of electrical energy. The offered device consists of wooden carcass construction supported by bars hammered into the soil. An isolated resistive electric heating cord fixing the convolvulus is fastened on said bars. It also serves as a local heating source. At the full length of heating cord are performed connections of special light diodes without the usage of any kind of internal feeding sources. These connections are performed by special brunch-industry clips made according to an IDC technology. A length of tapping step in the heating cord ensures its voltage drop for normal performance of spectral diodes. This is the way how manifests the co-generative impact of heating cords in the greenhouse convolvulus spectral lighting device. The device's exploitation safety increases due to the usage of voltage control of the heating cord and due to the device's automatic disconnection in the case of emergency.
