Abstract
The present invention relates to a discharge lamp which is filled with mercury, argon and halogen complex compound of alkalis and rare earth metals, such as samarium, ytterbium, etc., so that the discharge lamp emits characteristic spectrum, and has high light efficiency and high colour rendition. The mixture of yttria and barium zirconate is used as the material of a corresponding electrode.
Description
The invention belongs to the development technical field of gaseous discharge lamp.
In order to seek electric source material new in the gaseous discharge lamp, two during the last ten years, various transition metal, rare earth metal halide metal halide lamp single or that cooperate with other metal constantly occur
(1)The high-pressure discharge lamp that contains CsI
(2), SmI
2With the CsI research of luminosity etc. in different atmosphere (Ar or Xe) in varing proportions
(3), and some patent documentations are arranged
(4) (5)It is open also to have made relevant technology.
Because the vapour pressure of general halogen complex compound is greater than original halid vapour pressure, thereby light efficiency, color rendering and the spectral signature of gaseous discharge lamp distributed all will produces certain influence.Because excess iodine and HgI
2In lamp, influence the circulation of lamp inner emission.Simultaneously because light efficiency and life-span that electrode emission material barium zirconate that general halide lamp is adopted and rare earth compound effect influence lamp, employing yittrium oxide (can overcome above-mentioned shortcoming) starting resistor is higher again.Series of rare earth and alkali-metal iodo-complexes have been prepared as electric source material charges and new electrode emission material for this reason.
Task of the present invention provides a kind of gaseous discharge lamp with high light efficiency and special spectrum feature.For this reason, it is synthetic in advance halogen complex compound that gaseous discharge lamp of the present invention adopts charges, and promptly low price rare earth and alkali-metal ternary iodo-complexes make the light efficiency raising and have characteristic spectrum.And the mixture of 1: 1 yittrium oxide of gaseous discharge lamp employing of the present invention and barium zirconate is as electrode emission material, and experiment shows that this is a kind of desirable electrode emission material.
The major technique of gaseous discharge lamp of the present invention constitutes following two parts:
1. low price rare earth and alkali metal iodo-complexes is synthetic
Ln+HgI
2→LnI
2
LnI
2+ MI → MLnI
3, MLn
2I
5Deng
M-represents alkali metal in the formula, and Ln-represents rare earth metal.More than reaction is all in high vacuum (10
-6Holder) carries out in the quartz ampoule.
2. the manufacturing of rare earth and alkali metal iodo-complexes discharge lamp at a low price
Select the interior pipe and the outer tube of general 400 watts of high-pressure mercury lamps for use, electrode emission material is the mixture of yittrium oxide and barium zirconate, and charges are selectable rare earth and alkali metal iodo-complexes at a low price.The vacuum degree control of exhaust is 10 in the operating process
-5-10
-6Holder.Operating voltage is 220V.Because of fluorescent tube is universal, so make simple.
The made iodo-complexes lamp of the present invention can be used as photochemically reactive light source, because this lamp divides photo sensitivity can accomplish good coupling to a big chunk high-molecular photosensitive material, so than a large amount of energy of xenon lamp saving that use at present.
Accompanying drawing is the organigram of iodo-complexes lamp.1 is metallic support among the figure.2 is electrode, and 3 is quartz glass discharge vessel (interior pipe), and 4 is Bohemian glass shell (outer tube), and 5 for starting sheet, and 6 is lamp socket.
Experimental example 1-6(wherein example 2,3,5 and 6 is the embodiment of the invention);
The spectral signature distributed areas of experimental example 1-6 iodo-complexes and lamp thereof are listed in the table below:
| Sequence number | The synthetic reaction thing of forming filler | Weight (mg) | Mercury amount (mg) | Starting voltage (v) | Spectral signature distributed areas (nm) |
| １ | SmI 2 | 15 | 30 | 215 | 240～450 545～630 |
| ２ | SmI 2∶CsI | 20～25 | 40 | 220 | 312～590 is a large amount of line concentration spectrum |
| ３ | SmI∶2CsI | 25 | 40 | 220 | 365～495 |
| ４ | 2.5SmI 2∶CeI 3∶1.3CsI∶2.2NaI | 25 | 40 | 240 | 350～500 545～675 |
| 5 | 2YbI 2∶NaI | 26 | 40 | 210 | 364～494 546～670 |
| 6 | YbI 2∶CsI | 23 | 40 | 220 | Do not survey |
Claims (2)
