Abstract
The invention relates to a metal halogen lamp electrode component with extra small power, comprising a drawout molybdenum rod, a sealing-in molybdenum sheet, a transition molybdenum sheet and a batting electrode. The batting electrode is formed by straightening, cutting and chamfering a tungsten rod and making a ball shape at one end of the tungsten rod by an argon-arc welding method; the other end of the tungsten rod is coaxially welded with the sealing-in molybdenum sheet and the transition molybdenum sheet; and a transition molybdenum sheet is added between the tungsten rod and the sealing-in molybdenum sheet to form an electrode component. Compared with the prior art, the invention ensures the emission quality of the electrode, prolongs the service life of bulbs, and the like.
Description
Technical field
The present invention relates to lighting electric light source, relate in particular to a kind of metal halogen lamp electrode component of extra small power.
Background technology
Metal halide lamp is a kind of energy-efficient, long-life, photochromic good high-tech glow discharge spot lamp product, and its middle low power Metal halogen lamp is widely used in room lighting places such as guild hall, commercial building because compact conformation has the characteristics near color of sunshine again; Perhaps be applied to mobile class lightings such as portable search lamp, car headlamp.But up to now, no matter commodity class small-power Metal halogen lamp is to adopt quartz to make discharge tube, still adopts pottery to make discharge tube, and minimum power is all more than 35W.This is for the illumination of family expenses or commercial show window, and such as clock and watch, jewelry, jewellery class, historical relic, artistic class are difficult for the thermal-radiating article of the too big illumination of contact, is necessary that the Metal halogen lamp product of developing a kind of extra small power meets the need of market.
Summary of the invention
Purpose of the present invention is exactly to provide a kind of launch mass of electrode, metal halogen lamp electrode component with extra small power that bulb life is strengthened of guaranteeing for the defective that overcomes above-mentioned prior art existence.
Purpose of the present invention can be achieved through the following technical solutions: a kind of metal halogen lamp electrode component with extra small power, it is characterized in that, this electrode assemblie comprises draws molybdenum rod, sealing-in molybdenum sheet, transition molybdenum sheet, the electrode of playing ball, the described electrode of playing ball is that the tungsten bar is after alignment, cutting, chamfered, at one end getting the ball shape with argon arc welding method forms, the tungsten bar other end and sealing-in molybdenum sheet, draw the molybdenum rod coaxial welding, add the transition molybdenum sheet between described tungsten bar and the sealing-in molybdenum sheet, form an electrode assemblie.
The size of the described electrode of playing ball designs according to power requirement.
The described electrode of playing ball adopts the tungsten bar that contains 1% thorium tungsten, after alignment, cutting, chamfered, gets the ball shape with argon arc welding method at tungsten bar one end and makes.
Described play ball electrode and sealing-in molybdenum sheet, draw the molybdenum rod coaxial welding, and add the transition molybdenum sheet between tungsten bar and the molybdenum foil.
The bulb diameter of the described electrode of playing ball is 0.21mm～0.32mm, and the electrode length overall of playing ball is 6.6mm, and the diameter of tungsten bar is 0.089mm～0.178mm.
Compared with prior art, the metal halogen lamp electrode component of a kind of extra small power of the present invention comprises and draws molybdenum rod, sealing-in molybdenum sheet, transition molybdenum sheet, the electrode of playing ball; The tungsten bar is through alignment, cutting, after the chamfered, at one end get the ball shape with argon arc welding method, the other end and molybdenum foil, the molybdenum rod coaxial welding, add the transition molybdenum sheet between tungsten bar and the molybdenum foil, form an electrode assemblie, thereby overcome the high-temperature fusion phenomenon of electrode in discharge process effectively, guaranteed the launch mass of electrode, make bulb life reach designing requirement, fill up the vacancy of Metal halogen lamp light source product, exploitation 10W, the metal halogen lamp electrode component product of the extra small power of 20W class is met the need of market, thereby improves the series of Metal halogen lamp light source product.
Description of drawings
Fig. 1 is a metal halogen lamp electrode component with extra small power structural representation of the present invention;
Fig. 2 is the extra small power Metal halogen lamp of the present invention electrode structure schematic diagram of playing ball.
Embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
Shown in Fig. 1 and table 1, a kind of metal halogen lamp electrode component of extra small power, comprise and draw molybdenum rod 1, sealing-in molybdenum sheet 2, transition molybdenum sheet 3, the electrode 4 of playing ball, adopt coaxial method welding, play ball and add transition molybdenum sheet 3 between electrode 4 and the sealing-in aluminium foil 2, to strengthen the welding fastness, form an electrode assemblie.
For bulb integral body, electrode is a light emitting source, promptly is its cardiac component.The wire electrode footpath that the present invention relates to slightly is coarser than ordinary person's hairline footpath.Usually, the high-temperature fusion phenomenon that the electrode in the discharge tube produces owing to point discharge can influence the launch mass of electrode, causes bulb life to shorten.For fear of this point discharge phenomenon, the present invention's design also implements to adopt the argon arc welding processing mode, to make sphere-like (as shown in Figure 2) through the transmitting terminal of the thorium tungsten electrode after alignment, cutting, the chamfered, thereby overcome the high-temperature fusion phenomenon of electrode in discharge process effectively, guaranteed the launch mass of electrode, made bulb life reach designing requirement.
