Abstract
The utility model relates to a super-thin pipe diameter super-short double ends tungsten halide lamp, and two ends of a double spiral filament in a transparent quartz light tube is connected with molybdenum plates of two ends of the light tube, and the molybdenum plates which is connected with an electrode extract two electrode leading wires, and one end of a floral stent which supports the filament is fixed on a tube wall while the other end is connected with the double spiral filament, and the rings winded by the floral stent are mutually separated. The utility model which has the advantages of small volume, high light effect, long service life and convenient use can be widely used in indoor and outdoor common illuminations and local illuminations, and also can be arranged in a directional reflector to do spot illuminations, and the application area of the tungsten halide lamps can be expanded.
Description
Technical field:
The utility model relates to a kind of tungsten halogen lamp, relates in particular to the ultrashort double end tungsten halogen lamp of a kind of superfine pipe diameter, belongs to the electrical engineering and electric apparatus technical field.
Background technology:
Tungsten halogen lamp be by the tungsten filament of putting into the sealing glass-type tube as luminous element, charge into halogen (fluorine, chlorine, bromine, iodine) as halogen tungsten circulation agent, make Lamp bulb case keep clean, reach the purpose that prolongs bulb life.Tungsten halogen lamp of the prior art is single-ended tungsten halogen lamp all generally, as 120 volts/50 watts light sources in the reflection light projector (Par20 type) of packing into are single-ended tungsten halogen lamp.Two contact conductors of Single-ended Lamp are all drawn from an end of lamp, and two distance between electrodes are very little, are about 5mm, and adding between the glass bulb internal electrode has gas, and interpolar will be jumped electricity, with the disintegration of filament.Simultaneously because filament is to be formed by the tungsten filament coiling, higher at the light efficiency of filament design, under promptly lamp looked very bright situation, tungsten filament bore high temperature and the electronics emission is arranged, and just easier discharge causes the damage of lamp between the two poles of the earth.The life-span of therefore existing single-ended tungsten halogen lamp is shorter, and light efficiency is also lower.
The utility model content:
The purpose of this utility model is that at the deficiencies in the prior art design provides a kind of ultrashort double end tungsten halogen lamp of superfine pipe diameter of new structure, and not only volume is little to make it, and the life-span is long, the light efficiency height.
For realizing such purpose, the utility model has designed a kind of ultrashort double end tungsten halogen lamp of superfine pipe diameter of new structure, and its contact conductor is drawn from the two ends of lamp.Double end tungsten halogen lamp is made up of extraction electrode, molybdenum sheet, suprasil shell, fancy yarns coil support and coiled coil filament etc., lamp body inside is filled with the halogen tungsten recyclegas, the coiled coil filament two ends are connected with the molybdenum sheet of lamp tube ends, molybdenum sheet connects two electrodes respectively, and two contact conductors are drawn from fluorescent tube two.A fancy stent support coiled coil filament is set in the fluorescent tube, between the circle of fancy support coiling and the circle apart from one another by but not closely arrange, to strengthen support degree to filament.The number of turns of fancy support coiling is the 2-3.5 circle, quartz container and electrode sealing by fusing.
Double end tungsten halogen lamp of the present utility model, contact conductor is drawn from the two ends of lamp, anode-cathode distance is than big many of single-ended tungsten halogen lamp, therefore under same Power Supplies Condition, just can not jump, also little many of the possibility of interpolar discharge, thus can guarantee and prolong useful life of tungsten halogen lamp, improve the light efficiency of filament, and volume can do littler, realize the ultrashort version of superfine pipe diameter.The utlity model has light-operated effective, the light utilization efficiency height, the remarkable advantage that waits easy to use, its photochromic daylight that is similar to, photochromic high conformity, the moment of switching on can reach the output of 100% light, can be widely used in indoor and outdoor general lighting and localized lighting, also can pack into and do floodlighting in the beam reflector, enlarge the application of tungsten halogen lamp.
Description of drawings and embodiment:
Accompanying drawing 1 is a structural representation of the present utility model.
As shown in the figure, double end tungsten halogen lamp of the present utility model is made up of extraction electrode 1, molybdenum sheet 2, suprasil shell 3, fancy support 4 and coiled coil filament 6, filling halogen tungsten circulation gaseous mixture 5 in the suprasil shell 3, coiled coil filament 6 two ends in the fluorescent tube link to each other with the molybdenum sheet 2 of lamp tube ends, and molybdenum sheet 2 links to each other with electrode 1 and draws two contact conductors.4 one on the fancy support of filament supports 6 is fixed on the tube wall, and the other end links to each other with coiled coil filament 6, between the circle of fancy support 4 coilings and the circle apart from one another by, strengthen to support the dynamics of coiled coil filament 6.
An embodiment of the present utility model is 120 volts/50 watts ultrashort double end tungsten halogen lamps of superfine pipe diameter, suprasil pipe shell external diameter is 6 millimeters, length is 45 millimeters, the coiled coil filament that has the fancy stent support of a coiling 2.5 circles is done luminous element, contact conductor is drawn from lamp tube ends, the about 45mm of anode-cathode distance is about big many of the anode-cathode distance of 5mm than existing single-ended tungsten halogen lamp.The light efficiency of present embodiment reaches 14.5 lumens/watt, average life span 〉=2000 hour, and MaLS can reach 3500～4000 hours.Color rendering is the same with daylight, and promptly color rendering index is 100, has the continuous light tuning function.Because volume is very little, in the very little light projector of can packing into, light-operated performance is good, the utilance height of light simultaneously.
