The gaseous discharge lamp that commercially available high-power plant illumination is used, because of its luminous power is big, caloric value is bigger; In greenhouse irradiation, use at most at present, and in the intelligent greenhouse booth, applied, directly be used for the crop of modern agriculture factory, the cultivation of vegetables; Aspect such as garden landscape, flower gardening is strengthened prolonging photosynthesis of plant, satisfies the specific (special) requirements that different plants are liked different spectrum; Particularly the plant of low exposure of those needs and high-temperature grows up fast, plant was lacked under the natural lighting in winter also can grow up strong and sturdy fast, but area to be illuminated territory scope is greatly at 240 degree; Its brightness is not concentrated big not enough, and useful life is short.

Patent No. CN201120159927.1 " high-power plant illumination is used the mixed light high-intensity discharge lamp "; What provide only is that light emitting source is to be composed in series by high-pressure sodium lamp electric arc tube and metal halide arc tube; The orange light and the blue streak that can send different wave length are used for various plant illuminations place; Prolong the time of photosynthesis of plant, but its light efficiency is high not enough, useful life is short.

Patent No. CN200320103569.8 " Localized High Light Gas Discharge Lamp ", it only is at the interior of gaseous discharge lamp or outer surface plating one deck reflective membrane, is used for not having the window of coating to improve the luminous intensity of discharge lamp, increases the illumination of photographed object.Be widely used in the check of the quality and the true and false of medical exposure and banknote.

Summary of the invention

Technical problem to be solved by this invention is: a kind of superbright spectroscopic lamp is provided; Can be widely used in high-power plant illumination uses; The function of union light source and reflector still has high brightness in one though removed reflector, has improved the light output efficiency of illuminating lamp; And volume is little, in light weight, is prone to installation, long service life.

The present invention addresses the above problem the technical scheme that is adopted: the superbright spectroscopic lamp; Comprise that the support that is mounted with brace in lamp holder that the glass bulb end connects and the glass bulb is connected with wick; And the electric arc tube that is connected with wick, brace; Metal-coated membrane on the inner surface in the middle of the said glass bulb is a reflector layer, and described electric arc tube is installed at the reflector layer place that has that departs from glass bulb center line 1/4～1/2 glass bulb radius.

Compared with prior art, the invention has the advantages that: when the raw-gas discharge lamp used, the glass bulb and reflector two parts that need to have electric arc tube were installed at twice; And then use together, being equivalent to the effect of reflector on the existing inner surface that reflective membrane directly is plated on glass bulb, the function of light harvesting source and reflector is in one; Removed the reflector parts and only used this spectroscopic lamp separately, promptly but utilized the plated film of glass bulb arc angle, and controlled the distribution curve flux that the light source width of cloth is penetrated according to the ground furrow shape of planting plant in the greenhouse without reflector; The also direction of may command spectral radiance and angle have significantly reduced the volume and weight of lamp body, and brightness concentrates on the transparent place of glass bulb; Improved the illumination in area to be illuminated territory, made local luminance higher, light source is fully used energy-efficient; Spectral region wide from 350nm～800nm photosynthesis utilance up to more than 35%; As long as lamp holder inserted on the power socket just can use, to install and use more conveniently, this lamp directly can replenish the nature light intensity to plant illumination; Prolong the time of natural light irradiation, the secure replacement natural daylight.
