Abstract
Disclosed is a double-ended metal halide lamp which comprises molybdenum plates with molybdenum lead-out wires, rare earth electrodes, a quartz tube filled with rare earth material, wires provided with insulation sleeves, and joints. No glass shell is arranged outside the quartz tube, ceramic fixing frames are installed at two ends of the quartz tube respectively, and the molybdenum lead-out wires in the quartz tube are directly connected together with the wires provided with the insulation sleeves through the ceramic fixing frames. The double-ended metal halide lamp directly works without an outer glass shell, the ceramic fixing frames at the two ends of the quartz tube are fixed by aluminum oxide glue, the ceramic fixing frames are mounted on fixing pieces of the lamp, and the ceramic fixing frames are good insulation material and can be fully insulated from the lamp. When the halide lamp is turned on, the arc jumping phenomenon between lamps due to high-voltage pulse shock can be avoided; the electrodes, the molybdenum plates and the molybdenum lead-out wires are connected with the wires provided with the insulation sleeves via through holes on the ceramic fixing frames so that gas filled in the quartz tube can be ensured not to be leaked; the optical index better meets the requirements of specific sporting venues; the double-ended metal halide lamp is small in volume and can be installed intensively to achieve the purposes of high illumination and good color rendering property; and the position of a light source can be adjusted, and the light distribution curve is good.
Description
Technical field
The utility model relates to the Double ended metallic halogen lamp that a kind of lighting source, particularly a kind of illuminance in special-purpose motion occasion use is high and can intensive install and use.
Background technology
Along with improving constantly of people's living standard, people are also more and more higher to requirement healthy, living environment, people need to have high standard, modern stadiums, and good illumination occupies very important status in the modernization stadiums, good, suitable, uniform level, vertical illumination need to be provided, the reasonable Arrangement light fixture reduces dazzle and reaches bright and not dizzy lighting effect, with the vision requirement that satisfies sportsman, spectators and the requirement of high definition TV, need consider also simultaneously that illuminating engineering is installed, the convenience of debugging, maintenance.
But the Double ended metallic halogen lamp that uses in existing stadiums, all with outer glass shell, exist volume large, can not intensively install, so this lamp does not also reach the purpose that illumination is high, color rendering is good.
Patent No. CN201120291522.3 " 3000W-10000W both-end direct current metal halide lamp ", though a kind of halide lamp without outer glass shell also is provided, but its electric arc tube cavity is very little spheric, and more difficult making, processing, installation also are not suitable for using in stadiums.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of Double ended metallic halogen lamp is provided, without outer glass shell, its volume I is intensive installs, and installation and maintenance, simple and convenient, color rendering good, and degree of illuminating, optical index more can satisfy the needs of specific special-purpose sports center.
The technical scheme in the invention for solving the above technical problem is: Double ended metallic halogen lamp, comprise molybdenum sheet, rare earth element electrode with the molybdenum lead-out wire, be filled with the quartz ampoule of rare earth material, wire, the joint of tape insulation cover, described quartz ampoule is outer without glass shell, ceramic fixed mount is installed at the quartz ampoule two ends, and the molybdenum lead-out wire in quartz ampoule directly links into an integrated entity by the wire of ceramic fixed mount and tape insulation cover.
compared with prior art, the utility model has the advantage of: so the electric arc tube of lamp is directly to use under without outer glass shell state, work, and adopt at quartz ampoule two ends respectively with the fixing ceramic fixed mount of oxidation aluminium glue, be arranged on the fixture of light fixture by ceramic fixed mount again, because ceramic fixed mount is that good insulating material and light fixture fully insulate, when being started, metal halide lamp can avoid high-voltage pulse to impact the jumping arc phenomenon of cause and lamp locker, electrode effectively is connected by the wire of the through hole on ceramic fixed mount with the tape insulation cover with the molybdenum lead-out wire, guaranteed that the blanketing gas in quartz ampoule does not unload leakage, while is because of the mounting means of the ceramic fixed mount of electric arc tube two ends employing, can also effectively improve the adjustable of light angle, easier for installation, optical index satisfies the use in special exercise place more.Because of without outer glass shell, and be the oval tubular of small volume, easily regulate position and the brightness of light source, and can intensity install and use, reach the purpose that illumination is high, color rendering is good, go back distribution curve flux good.
Description of drawings
Accompanying drawing 1, structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Rare earth element electrode 6 is suppressed sealing-in with the molybdenum sheet 7 with molybdenum lead-out wire 10 in the cavity at quartz ampoule 1 two ends by the high-temperature digestion technology.
Pottery fixed mount 2 is the middle tubular that through hole is arranged, be fixedly mounted on the quartz ampoule 1 middle indentation, there of two ends compacting sealing-in place outer surface with the oxidation aluminium glue, one end of the molybdenum lead-out wire 10 on molybdenum sheet 7 passes the through hole in the middle of ceramic fixed mount 2, is welded and fixed with an end with the wire 3 of insulating case 4 to be integral.The joint 5 of the other end of wire 3 and fork-shaped copper product is integrally welded.Rare earth luminescent material 8 is filled in quartz ampoule 1 cavity by quartzy blast pipe 9, and with special equipment, quartzy blast pipe 9 is connected with vacuum inflation system, the foreign gas in quartz ampoule 1 is pumped and be filled with startup gas, Double ended metallic halogen lamp is assembled into.
Electric arc tube is filled rare earth material, mercury, high-purity argon gas by quartz ampoule 1, consist of with molybdenum sheet 7, the rare earth element electrode 6 of molybdenum lead-out wire 10 in electric arc tube, alumina powder is coated on the outer surface at rare earth element electrode two ends with the heating coated technique.
During use, ceramic fixed mount is arranged on the fixture of light fixture, and the output of the supporting rectifier of the joint 5 at electric arc tube two ends and halide lamp is connected.
The electric arc tube two ends adopt rare earth element electrode to make emissive material, and metal halide lamp connects AC power, when there is voltage at its two ends, make rare earth element electrode puncture the generation arc discharge by high-voltage pulse, light metal halide lamp, electrode alternately becomes negative electrode, anode, and two electrodes have same function.
When electrode is in negative electrode, be mainly that thermionic emission is occupied an leading position, electrode institute calorific requirement is subject to the shock of cation when coming from it as negative electrode, be subject to the shock of electronics during as anode, carries out work by electron emission, heat conduction, thermal radiation.
During work, the optical parameter color rendering index Ra that metal halide lamp sends 〉=70, colour temperature 4000 ± 200K, light efficiency 90Lm/W.
