SU509915A1 - Metal halide lamp for irradiating plants - Google Patents

Description

one

The invention relates to gas-discharging sources of light, in PRSTNOOTI intended: HM1M FOR, irradiation of plants,

. Known (ed. St. 326666) metallographic lamp with mercury. “Burner burner, 5 (containing additives of lithium iodides and and ndy. Burner on the external flask, made of refractory glass. The lamp has | increased compared to type lamps (DRL phtoresol due to resonant lithium 10 lithium and indium emitted in the red and blue regions of the spectrum.

The most significant disadvantages of the {known lamp are:

1. Small Art} 0k lamp service, containing- 11 imeft lithium,

2. Linear radiation spectrum in the region of photosynthetically active radiation (PAR).

3. Strong line radiation of the RSU,: UPBTRfierlet region (UV) spectrum .. 20

4. The complexity of the design of the lamp and the technology of its manufacture, as the burner; . the lamp is placed in an external flask, playing the role of a thermostat and absorbing radiation,

: 5. Low reliability of the lamp, cBJb is associated with a large starting current and present; I have a large number of elements in the external

flask,

} The purpose of the invention is to eliminate these.

limitations,

The post-obstructed goal is achieved by the fact that, as additives, tin iodides, indium and lithium QJ amount are selected, respectively: 0.5-O, 8 mg4; m; 0.05-0.15; 0,, 06 mg / cm with a minimum operating Tei4 temperature of the discharge bulb 700 C. In qualities. We can use an incendiary gas, xenon at a pressure of 90-150 mmHg. Art. (In addition, the discharge of the x-forehead can be {made of | doped quartz that absorbs UV radiation shorter than 300–380 nM,

. . -. .i

The proposed discharge of the lamp does not have the indicated disadvantages. In addition, insulated electrode nodes. A sufficiently effective | TivnyM | In this way, the lamp can be operated without an additional external bulb, and the burning position does not play an essential role.
