Electric lighting devices such as metal lampshades, suspended on stretch marks, are almost inconvenient because at the slightest wind begins to sway and create an unpleasant oscillating lighting. Patio lighting is quite a serious thing and you need to be prepared for it!
The main requirement for street lamps is to ensure the insulation of the conductive parts from moisture penetration. They must be equipped with metal lampshades to protect glass ceiling lamps and bulbs from rain droplets, which can cause the lamp to explode. The metal parts of the lamps must be grounded securely.
For this purpose, a metal pin is hammered into the soil to a depth of about 1 m and connected to the metal parts by welding or soldering using a flexible wire. Patio lighting in this way is a good option!
Patio Lighting. Construction
The construction of such a light is not very difficult. From a metal pipe 35 … 45 mm in diameter make a rack and fasten it with the bottom end in the base of concrete or brick. From above a washer with a ring for fixing the plafond and brackets of the lampshade cover is installed. The configuration and dimensions of these parts must correspond to a ready-made, pre-selected glass plafond.
The cover shall be cut out of sheet iron and riveted as a hollow cone; it shall be easily removable for replacement of the plafond and lamp.
The biggest difficulty is laying the underground part of the electric cable – hidden wiring to fixed lamps. At a patio location near the house it is not difficult to do it, at its considerable distance from the house it is expedient to apply combined wiring: the main part of it to make an air cable, the rest – underground.
In the latter case, use a cable in lead sheathing or rubber with double insulation, which is laid in a plastic or asbestos cement pipe. The street part of the wiring should be made of solid cable without connections; the air part should be carried out on poles with the help of brackets or on the bottom edge of the top left of the wooden fence. The same wiring should be done for sockets (they must have covers) for portable lights; they should be installed under a special canopy or in a niche.
In all cases, the switches of the street network must be in the house and must necessarily disconnect the phase conductor.
It is easy to make a portable lamp-tosher from handy materials. For example, any large metal or plastic jar that fits the configuration and size can be used for the shade cover. Patio lighting with such a lamp is not very difficult!
A pipe with a diameter of 22 … 25 mm is selected for a rack. The base of the lamp is made of concrete, using a small conical metal bucket as a formwork. For better reinforcement in concrete, a hole is drilled in the lower part of the pipe and a bolt made of 5 … 6 mm diameter reinforcement wire is inserted.
The clip for fixing the chuck and switch is cut out of 1.5 … 2 mm thick sheet steel. Electric cartridge, push-button type switch and two-core cable in rubber insulation are used from electrical fittings. The whole structure is connected by two through bolts with diameter of 5 … 6 mm; a hole for fastening to a rack at a can of a cap-shade is desirable to make on a seam in the most rigid place.
Patio Lighting. Fire
Lighting of the patio in the evening attracts many mosquitoes and other insects. To get rid of them ignite a fire in flat with a pallet, which is poured water with a surface layer (1 … 2 mm) of kerosene or 1% solution of laundry soap (washing powder).
The patio can be equipped with a special device with a light – light trap. Its main element is a spiral (for example, from an electric tile), which is stretched on the frame with the help of porcelain rollers. As a lighting can be used any lamps, including fluorescent lamps. The casing is made of galvanized sheet iron.
The unit can also be used as a street light, but in this case the cut-out in the casing must be covered with glass.
