The experiment shows that the utility model discloses the light source has that load intensity is high (several times higher than the iodine tungsten lamp), and radiant efficiency is high (more than 60% higher than the iodine tungsten lamp), and the colour temperature 6500 ℃, is about 3000K higher than the iodine tungsten lamp. Its spectrum is very close to the solar spectrum.
Description
Technical field
The utility model relates to light source, particularly a kind of sun simulating light source that can be used as the solar battery array detection.
Technical background
Solar cell detects iodine-tungsten lamp, xenon short-act lamp or the xenon flash lamps etc. of adopting as sun simulating light source more at present, and the illumination that its utilization mostly is the small size zone detects, and is mainly used in the irradiation test of monolithic solar cell.
For satisfying the requirement of Aero-Space solar battery array ground test, need to realize the irradiation effect of the high illumination simulated solar irradiation of a kind of large tracts of land, thereby require light source that very high intensity of load and higher radiation efficiency must be arranged and near the radiation temperature on sun surface.The light source of simulated solar irradiation needs than high radiance, must use the radiation source of the approximate sun of high light intensity, high capacity intensity and spectrum.
Though normally used xenon flash lamp has high brightness, but its fluorescent lifetime has only delicate to the millisecond magnitude, so require the testing equipment of solar battery array under transient state, to work, and pulsing light can not make solar battery array continous-stable electromotive power output test for multinomial performance.And the operating voltage of xenon short-act lamp is low, the cost height, and fried lamp takes place easily.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and in order to satisfy the The application of new technique requirement, the utility model provides a kind of sun simulating light source that solar battery array detects that is used for.This light source should have the intensity of load height, radiation efficiency height, the characteristics that colour temperature is high.
Technical solution of the present utility model is as follows:
A kind of sun simulating light source that is used for the solar battery array detection, be characterised in that and adopt the continuous xenon lamp of high-purity high grade quartz pipe and tubbiness type fluorescent tube to make light source, the negative electrode of this continuous xenon lamp is processed into tip with exotic material, with the anode of refractory materials processing one-tenth with hot isolating trenches.
The tip of described negative electrode is a spear shape tip.
Also be provided with quartzy duct set outside the described continuous xenon lamp fluorescent tube.
Technique effect of the present utility model:
Because the light efficiency of xenon lamp improves with input power continuously, the slender type lamp is subject to driving power voltage, input power density deficiency, so illuminating effect is poor, carefully the power of short lamp load is low, so both radiation efficiencies are not high.Analog light source of the present utility model is selected the continuous xenon lamp of tubbiness lamp type for use, and light efficiency improves greatly with the raising of input power.
Continuous xenon lamp fluorescent tube of the present utility model is selected high-purity high grade quartz pipe for use, and working temperature can reach 850 ℃.
Continuous xenon lamp of the present utility model, negative electrode select for use the dispenser-type exotic material to be processed into spear shape tip, and when driving with DC power supply, tip cathode emission electronic capability is stronger, are easy to start.Reduce its work function, improve the performance of emitting electrons, increase radiation and imitate.Anode improves its hyperthermia radiation and cools off performance and heat-proof quality certainly, thereby reduce the working temperature of conduction portion with the shape of refractory materials processing one-tenth with hot isolating trenches, guarantees light source safety, long-life operation.
The results showed that the utility model light source has intensity of load height (than the high several times of iodine-tungsten lamp), radiation efficiency height (higher more than 60%) than iodine-tungsten lamp, 6500 ℃ of colour temperatures are than the high about 3000K of iodine-tungsten lamp.Its spectrum and solar spectrum are very approaching.So estimate from radiation intensity and spectrum two aspects, it more approaches sunlight than the iodine-tungsten lamp that is called " Sunny " usually.

Embodiment
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing, but should not limit protection range of the present utility model with this.
See also Fig. 1 earlier, Fig. 1 is the organigram of the utility model embodiment 1.For taking into account radiation efficiency and impedance matching and reaching reliable triggering, the continuous xenon lamp of present embodiment sun simulating light source is selected the fluorescent tube 3 of high-purity high grade quartz pipe of tubbiness cast and higher inflation pressure for use, and its working temperature can reach 850 ℃.Negative electrode 1 uses the anti-bombardment of dispenser-type, exotic material, and is processed into tip to reduce its work function, improves the performance of emitting electrons.Anode 2 adopts refractory material to be processed into and is with hot isolating trenches shape 4, to improve its heat-proof quality and hyperthermia radiation from cooling off performance.Thereby reduce the working temperature of conduction portion 5,6, guarantee light source safety, long-life operation.
Preferably continuous xenon lamp 2-3 of the present utility model is propped up lamp series connection and use, each lamp service area all is selected in positive resistance region, so good stability, its impedance sum can with the direct commutating voltage of three-phase (unloaded about 510V) approximate match, and leave bigger adjustable leeway.
The external diameter φ 16mm of the fluorescent tube of the continuous xenon lamp of present embodiment, discharge arc length 150mm, operating current 10-16A, the series connection of 2-3 lamp, the about 300V of overall presure drop can be close with the voltage after the direct rectification of three-phase, the leeway that adjusting is also arranged, the average tube wall power termination 15-25W/cm of lamp
