Holland Mesh Fence
* Using high quality iron rod as raw
material, the welded panel or rolled fence, after Galvanization, PVC
Powders dipped coating; it can resist the corrosive and ultraviolet
radiation very strongly.
Selection of high-quality wire welded
together, the PVC or PE, PP powder after curing the surface of the
coating, with strong adhesion, corrosion resistance, bright color and so
on.
Manufacturing process: steel wire after the plastic coating, but also a separate plating, hot-dip and plastic coating.
* Mushroom special Tubes (48*1.5mm) is designed refined and scientific, with plastic caps on the top of the post.
The finished surface usually is
Galvanized and Powder coating, or alternatively. It usually uses
installation method of burying additional 50 cm pass panels height into
the earth. Special sizes can be provided as the client`s request.

LED fill light is a solid light emitting device, also known as light emitting diodes, driven by a small current to light semiconductor devices, low power consumption, high stability, but the brightness is relatively weaker. Less heat, good heat dissipation. Get close to the plant without burning it. Based on this characteristic, the LED can be placed horizontally or vertically above the plant, so it can reduce illuminance loss and provide light efficiency to a great extent.
(a) The principle of infrared light emitting diodes (LEDs). Infrared light emitters consist of an infrared light emitting diode (LED) matrix. The infrared light emitting diode is made of a material with high infrared radiation efficiency and made of a PN junction, and a forward bias is applied to inject the current into the PN junction to excite the infrared light. Spectral power distribution is center wavelength 830 -- 950nm, half-peak bandwidth is about 40nm, as shown in Figure 1 (850nm, 940nm infrared light-emitting diode spectral distribution diagram) shown. It is a narrowband distribution, which is the range that can be felt by ordinary CCD black-and-white cameras. Its greatest advantage is that it can be completely free of red storms (using infrared tubes at 940 to 950 nm wavelength) or only weak red (using infrared tubes at 850 nm wavelength); it also has a long lifetime.
(b) Light-controlled soft-switching circuit circuits. The infrared fill light adopts the light control soft switch circuit, in order to reduce the impact of its working state conversion and prolong the service life of the infrared lamp.
(C) Regulated constant current circuit. In order to compensate for the infrared light radiation power difference between the infrared light in winter and summer, the infrared light adopts a constant voltage and constant current circuit, so that the infrared light emitting diode has stable optical power, thereby improving the use effect of the infrared light and prolonging the service life.
(d) Selection and use of infrared lamps. The most important issue in the selection of infrared fill light is the completeness of the infrared light and the camera, lens, protective cover, power supply and so on. Some people bought the camera, lens, protective cover, power supply, and even considered the purchase of infrared light after installation. This is not correct. All equipment should be taken into consideration when designing the project. Think of it as an infrared low-light night. Designed as a monitoring system project.
