LV11655B - Equipment for artificial lighting and watering - Google Patents

Abstract

The invention refers to lighting systems and could primarily be used in greenhouses for raising seedlings. The invention is designed to unify the constructive elements of the device, to minimize costs and to save energy. The essence of the invention is that, unlike a known device which consists of sprinklers from a water tank of light electro-insulating materials impenetrable to light and with mutually insulated sections, which operate as hydro-resistive ballast resistors in schemes of luminescent bulbs located outside this tank, in the new device "U" or "W" type luminescent bulbs of pipe-shaped bodies are located on movable contact plates inserted in the light penetrable water tank of electro-insulating material, which can be used for the watering of plants. The water layer between the plates functions as an adjustable hydro-resistive ballast resistor, whereas the tank itself functions as a luminescent bulb lighting fixture and water boiler body.

Description of the Invention

ARTIFICIAL LIGHTING AND WATERPROOFING PLANT

The invention relates to lighting systems and can be used mainly for growing nurseries in greenhouses.

There is known a device consisting of fluorescent lamps connected to mains through inductive ballasts and a metallic watering plant with an electric heater [1]. Such a device is economically disadvantageous, as the ballasts for fluorescent lamps lose about 30% of their electricity, they are not adjustable, and their electrical circuit is complicated and expensive. The special water heater also makes the equipment more expensive.

Closer to the invention is an apparatus consisting of a water-resistant, water-resistant, waterproof pot of waterproof material of insulating material, with interconnected sections serving as adjustable water-resistant ballast resistances [2] in circuits of fluorescent lamps placed outside this pot.

However, the design of this unit is also not compact enough, the fluorescent lamps do not provide optimum starting conditions and operating parameters, thus hiding some energy and financial reserves.

The object of the invention is to unify the structural elements of the equipment, reduce the capital investment and improve the energy parameters.

The target is achieved by placing the U or W fluorescent lamps 14 in a container 16 of light-transmitting electrical insulating material (glass, plastic) filled with water 11. A sliding metallic contact plate 12 and 15 is disposed on the water tube part. the plates perform the functions of an adjustable water-resistant ballast resistance, but the vessel itself serves both as a fluorescent lamp fixture and a water heater housing.

As is known [1], the water surrounding the fluorescent lamp increases its light output by 1.5 to 2 times and improves the starting conditions by indirectly acting as an additional ignition electrode.

The operation of fluorescent lamps depends on the ambient temperature [3], so it is possible to create optimum operating conditions by heating the water to the appropriate temperature.

1. shows the connection scheme of electrical and technological elements of artificial lighting and watering plant.

The machine is designed as follows. Phase lead A is connected to one of the electrode outputs of the non-water-based fluorescent bulb and the other to waterproof insulation wire 13 from the contact strip 15. The contact strip 12 is connected to mains zero via wire 2.

In order to maintain the required ^T go temperature around the tubes of the fluorescent lamps 14, an adjustable water flow through the vessels 11 is provided by means of a tap 4.

The irrigation water system uses rubber or plastic pipes 5 (not shorter than 1 meter) to prevent the appearance of hazardous electrical potential on the metallic, non-conductive parts of the machine.

These tubes are sealed to the nozzles 10 of the plastic lid 7 of the receptacle 16 screwed into place.

Drip irrigation of the plants with heated water takes place through locally created perforation sections 6 along the entire length of the pipes 5.

The electrical circuitry of the machine operates as follows. When the switch 1 is closed, the fluorescent lamp through the water-ballast resistive hydro-resistivity between the contact plates 12 and 15 receives the full phase voltage at the cold-end electrodes 8 and 9. By connecting the contacts of the trigger button 3, the filaments of the electrodes heat.

Due to the fact that the tubes of fluorescent lamps are placed in self-priming water tanks without special lighting fixtures and emit sufficient heat during their lifetime, the unit's design uniformity reaches 20% with a simultaneous reduction of capital investment by 25%. The increase in light output due to the effect of the water layer surrounding the lamp tube results in 30% energy savings.
