A reflector lamp for greenhouse

 

(57) Abstract:

The use of agriculture in the field of crop production in buildings protected ground. The inventive reflector lamp for greenhouse contains the frame 1 and the reflective plate. The frame is made of two iterative holders 2, consisting of the top 3, two lateral 4,5 and two lower 6,7 sequentially and pivotally connected rods. The upper pair of reflective plates 8,9 ends hinged to the ends of the top 3 rod holders 2, and the second pair of ends rigidly connected with the ends of the two side 4.5 rods, the opposite ends of which are connected with the top 3 rod holders 2. C.p. f-crystals, 2 Il.

The invention relates to agriculture, in particular to the greenhouse under artificial irradiation.

Known reflector lamp for greenhouse, containing the framework and the reflective plate (ed. St. USSR N 956907 M CL F 21 7/12, 7/16, 1980).

The disadvantage of this reflector is that its shape does not provide the uniformity of exposure of the plants due to the limited regulation of the direction of the light flux and a bulky device, complicating Transporter the irradiation, the quality of the radiation regime and reduce the size of the structure.

The problem is solved in that the reflector lamp for greenhouse, containing the framework and the reflective plate according to the invention, the frame is made in the form of two located at its opposite ends multilink holders, each of which consists of at least the top, two side and two lower sequentially and pivotally interconnected ends of the rods, and a reflective plate of the first pair of ends attached swivel and can be locked in position at opposite ends of the upper rod of each carrier, and the reflective plate of the second pair of ends rigidly connected with the ends of the two side rods of each holder, the opposite ends of which are connected with the upper terminal of the respective holder.

In a preferred embodiment, the lower terminals of both holders are fixed zvetokorrekcia screens made louvered blinds are covered with reflective material.

Preferably cvetokorrekcii screen consists of a series set of sections svetoservice transmittance of the incident optical flux in the spectral range 400 to 500 nm, the second plate in the region of 500-600 nm, and the third plate is in the range of 600-700 nm.

The invention is illustrated in the drawing, where Fig.1 shows a reflector lamp in working position: Fig.2 the reflector in the transport position.

A reflector lamp for greenhouse contains a frame 1 made in the form of two near opposite ends of the holders 2 (one holder not shown). The holders 2 are composed of five sequentially and pivotally interconnected ends of the rods: the top 3, two sides 4, 5 and two bottom 6, 7.

At both ends of the upper rod 3 each holder 2 ends hinged reflective plates 8, 9 of the first pair, which are attached to the framework 10 swing covers 11 and fixed in position at opposite ends of the upper rod 3 holders 2. With the ends of the two side rods 4, 5 holders 2 are rigidly connected reflective plates 12, 13 of the second pair. The opposite ends of the plates 12, 13 are connected with the side bars 4, 5 and attached to the framework 14.

On the lower rods 6, 7 holders 2 are fixed zvetokorrekcia screens 15, plate (blinds) 16 which is covered svetootrazhayuschimi plates, the first plate of each section is made from a material with a specified value of the transmittance of the incident optical flux in the spectral range 400 to 500 nm, the second plate in the region of 500-600 nm, and the third plate is in the range of 600-700 nm.

Position 17 shows the light irradiation position 18 start-control devices (BALLAST) lamp 17.

A reflector lamp of the greenhouse works as follows:

The light output from the illuminator 17 (see Fig.1) passes through an aperture in the reflector, limited reflective plates 8 and 9 and main reflectors 12, 13. Second, the main thread of light passes reflected from the reflective plates 12, 13, and directly through zvetokorrekcia screens 15. Thus, the plates 8, 9 catch the light "lost" when passing a primary flow of light. For rational use of light, the rotation angles of the reflective plates 8, 9, 12, 13 can be changed.

Via formed between the upper ends of the reflective plate 12, 13 is removed the heat radiator 17, preventing it from overheating.

Zvetokorrekcia screens govern the spectral composition of light needed for optimal obci (Fig.2).

The use of a reflector lamp of the greenhouse will allow 8-15% to improve the effectiveness of exposure and quality management regime to reduce the dimensions during transport.
