Description
Technical field
The invention belongs to ceramic light source field, relate in particular to a kind of efficient ceramic lamp.
Background technology
The ceramic arc tubular construction is directly connected to process for sealing.Sealing-in is the key technology of ceramic discharge light source, and the quality of sealing-in is directly connected to the performance and the life-span of electric arc tube.The sealing technology of ceramic discharge tube is different from quartz, quartz metal halide lamp is to shrink sealing-in or compression sealing-in by melting quartz with electrode or electrode assemblie, pottery should not melt after moulding, pottery is to fill pottery by glass solder to finish with the slit of electrode with the sealing-in of electrode or electrode assemblie, see shown in Figure 1, comprising discharge cavity 6, be located at its two end electrodes pipe 2 and be plugged in electrode assemblie in the electrode tube 2, electrode assemblie comprises the electrode tip that is positioned at discharge cavity 5 that connects successively, welding is realized in the gap 4 that molybdenum filament 3 and niobium pipe 1, scolder flow between electrode tube 2 and electrode assemblie.
Accomplish air-tightness completely, at present main sealing technology is to be two capillaries with the ceramic discharge tube pin design, forms little gap between its internal diameter and electrode assemblie.In the sealing-in process, glass solder and ceramic discharge tube and electrode are together heated.The fusing point of glass solder is lower than the softening point of pottery, and good flowability is arranged after fusing, and then is penetrated in the gap of ceramic capillary and electrode assemblie.Finish the sealing-in of earthenware after cooling.The present this sealing technology of in capillary, finishing of the nearly all whole employings of ceramic gold-halogen lamp.
Sealing-in was divided into for two steps: the first step, and with top description elder generation front cover end, i.e. an envelope.Inflation adds metal halide pill and mercury then, in the envelope other end, i.e. two envelopes.
The occupied state of scolder in ceramic capillary and electrode assemblie gap, as filling the degree of depth, uniformity, tightness comprises the materials behavior of scolder itself, is that the key of assurance ceramic lamp quality also is a difficult point.Because it is directly connected to the air-tightness of ceramic lamp.Yet in this kind hermetically-sealed construction, glass solder is arranged in the gap of capillary and electrode assemblie, in case electric arc tube when work, the luminescent substance in the discharge cavity infiltrates the gap, and at high temperature reacts with glass solder and to cause luminescent substance loss and the sealing of infringement scolder.And this kind sealing technology is very complicated.
Summary of the invention
At the shortcoming of prior art, the purpose of this invention is to provide the efficient ceramic lamp of a kind of luminous efficiency height, good sealing effect.
For achieving the above object, technical scheme of the present invention is: a kind of efficient ceramic lamp, comprise discharge cavity, be located at the electrode tube on discharge cavity both sides and stretch into electrode assemblie in the discharge cavity by electrode tube, this electrode tube comprises interior pipeline section and the welding groove that is connected, pipeline section is near discharge cavity in being somebody's turn to do, welding groove is positioned at the end, and the interior pipeline section of the internal diameter of welding groove is big, and welding groove is realized the gas-tight seal of discharge cavity by filling scolder.
In this programme, adopt and form a welding groove structure in the end of electrode tube, the mouth of pipe is transferred to by the electrode tube wall in sealing-in position in the past, the diameter of the mouth of pipe is bigger, greatly facilitates to put scolder and finish sealing-in.
And scolder melts and finishes sealing-in at welding groove substantially, and does not need to finish sealing-in by the quite long electrode tube wall that flow to.
In addition, further from the high arc temperature district, the length of electrode tube can correspondingly reduce scolder, helps some to the shorter and smaller application of electric arc tube yardstick requirement compared with the technology of welding in prior art.
The cold junction position of this scheme can effectively be controlled forward, owing to more near the thermal source part, improved cold junction temperature, guarantees the operating pressure of light source.
Further, this electrode assemblie comprises tungsten plug, conducting rod and the lead-in wire that is connected successively, this tungsten plug stretches in the discharge cavity, this conducting rod is positioned at pipeline section, and the external diameter of conducting rod is suitable with the internal diameter of interior pipeline section, and lead-in wire stretches out outside the electrode tube with the terminal scolder that is connected and passes in the welding groove of conducting rod.

Lead-in wire stretches out outside the electrode tube with the terminal scolder that is connected and passes in the welding groove of conducting rod.Because the electrode tube inwall not have the function of welding, electrode tube and electrode assemblie can reduce the gap as much as possible, enter the electrode tube gap and the loss that brings with obstruction mercury and halide.
Further, this conducting rod is a cermet rod.Because mainly in interior pipeline section, its function is the conduction of carrying electric current and stopping heat effectively to the cermet rod part.Add a lead-in wire, be used for joining with external circuit.The coefficient of expansion of this cermet rod and electrode tube are very approaching, can effectively avoid because the coefficient of expansion of electrode tube or conducting rod is inconsistent, and the electrode tube that causes break or has the gap.Less clearance has prevented effectively that luminescent substance such as halide and mercury from entering the gap and the loss of the luminescent substance that brings and the light efficiency that causes thus lower and the change in color of light.
This conducting rod end is provided with the boss structure that cooperates the location with welding groove.During sealing-in, electrode assemblie is injected in the electrode tube, because the effect of boss structure, electrode assemblie can be positioned at predeterminated position well, behind the plug-in mounting, again filler is filled on the solder bath, in this scheme, because scolder is not to be filled in the gap of electrode assemblie and electrode tube, can effectively reduce the complexity of sealing technology.
This boss structure top is formed with the some kinds of conical surfaces, makes easier wetting welding groove of scolder and electrode.
Further, come off by solder bath for preventing the aging back of scolder, this welding groove is an outside throat structure, and throat structure applies an axial pressure for the overall structure of scolder, can prevent effectively that it from coming off.
Further, this welding groove can be frustum cone structure or spherical structure.
Similarly, also can be provided with on this welding groove side some recessed/the tongue structure, groove/tongue structure has grasp to scolder integral body, can prevent effectively that the aging back of scolder from being come off by solder bath.
Further, the internal diameter size of this welding groove is in 1 to 4 millimeter scope, and the degree of depth is at the 1-4 millimeter, and interior pipeline section internal diameter is in 0.4-1.5 millimeter scope.
The positive camber of this discharge cavity and the junction of electrode tube are the smooth transition structure, avoid acute angle curvature, to reduce the stress of ceramic lamp.
The present invention compared with prior art has following advantage and beneficial effect:
The present invention forms a welding groove structure by the end at electrode tube, and the mouth of pipe is transferred to by the electrode tube wall in sealing-in position in the past, and the diameter of the mouth of pipe is bigger, greatly facilitates to put scolder and finish sealing-in.
