Abstract
The invention relates to a method for improving the detection accuracy of a standard lamp. The method includes the steps that (1) a glass core column is arranged between a lamp holder and a lamp housing, two conducting wires are led out from the interior of the glass core column, the whole conducting wires are kept in the vertical state, and the top ends of the conducting wires are bent to form horizontal sections; (2) a lamp filament is arranged, is in a square wave shape from left to right and is located in the same plane; (3) the two ends of the lamp filament are connected with the horizontal sections of the conducting wires respectively, and adjustment is carried out, so that the distance between the plane where the lamp filament is located and the front side of the lamp housing and the distance between the plane where the lamp filament is located and the back side of the lamp housing are equal, and the distance between the left end of the lamp filament and the left side of the lamp housing and the distance between the right end of the lamp filament and the right side of the lamp housing are equal; (4) a fixing strip is connected to the horizontal section of each conducting wire in a spot welding mode for fixing the lamp filament. By means of the method, the lamp filament and a support are arranged in different planes, the defect that lamp light is shielded by the support is well overcome, and therefore the detection accuracy is greatly improved.
Description
Technical field
The invention belongs to light fixture manufacturing technology field, particularly a kind of method improving standard lamp detection accuracy.
Background technology
In optical radiation measurements, reappear the primary standard of various luminosity and radiometric quantities list as blackbody furnace, absolute radiometer etc., technical sophistication, take costliness, often should not remain on operating state, be more not easy to use in real work.Therefore need position value that primary standard reappears by corresponding standard lamp to copy down and be used as secondary standard, transmit the value that it keeps step by step.Luminous intensity standard lamp is for reappearing and transmit the standard lamp of unit of luminous intensity's value.Its stable luminescent property, filament is in same plane.Lamp housing has given shape, can adapt to inverse distance squares method requirement then very well.Standard lamp conventional at present, its filament and support are in same plane, and stent diameter is much larger than filament diameter, and from the side, support height is greater than filament height, and stent diameter is much larger than filament diameter, when detecting, along viewed in plan residing for filament, filament is blocked by support completely, be difficult to observe the projection and filament itself that filament light-emitting is reflected back whether overlap, harmful effect is caused to certainty of measurement, also unfavorable to the centering of filament.
Summary of the invention
The object of the invention is to overcome above shortcomings in prior art, and provide a kind of method that standard lamp detects accuracy that improves, the standard lamp manufactured by this method can be solved light very well and be blocked by support, to the disadvantageous problem of filament centering precision.
The present invention's adopted technical scheme that solves the problem is:
Improve the method that standard lamp detects accuracy, its step comprises:
Step one, between lamp holder and lamp housing, arrange glass stem, in glass stem, draw two seal wires, seal wire entirety keeps vertical state, is bent to form horizontal segment at its top end;
Step 2, arrange a filament, this filament is from left to right in square-wave-shaped, and filament is all in same plane;
Step 3, the horizontal segment of filament two ends respectively at seal wire is connected, make filament place plane equal to the distance of both sides, front and back lamp housing by adjustment, the left end of filament is equal to the distance of the lamp housing on right side with the right-hand member of filament to the distance of the lamp housing in left side;
Step 4, on the horizontal segment of seal wire spot welding connect a fixed strip, in order to anchored filament position.
As preferably, in described step one, in seal wire lower end by bending, the spacing of guidewire tip horizontal segment is strengthened.
As preferably, described lamp housing is spheroidal.
The present invention compared with prior art, has the following advantages and effect: filament and seal wire are arranged in Different Plane, solves the defect that light is blocked by seal wire well, thus substantially increases the precision of detection.Lamp housing adopts spherical, and filament is arranged on the centre of lamp housing, makes lamp housing all directions overlap at filament place to the reverberation of filament, both decreases stray light, and strengthens again the stability of photoluminescence of filament; Filament adopts square-wave-shaped, and vertical direction filament length is greater than the length of horizontal direction filament, makes filament not easily sagging, and job stability is strong, long service life.Fixed strip is set by spot welding, thus ensures that filament is stable and not easily rock or come off.

Fig. 1 is the structural representation of the embodiment of the present invention.
Fig. 2 is the front view of the embodiment of the present invention.
Fig. 3 is the lateral plan of the embodiment of the present invention.
Embodiment
Below in conjunction with accompanying drawing, also by embodiment, the present invention is described in further detail, and following examples are explanation of the invention and the present invention is not limited to following examples.
As shown in Figure 1, Figure 2 and Figure 3, a kind of method improving standard lamp detection accuracy, its step comprises:
Step one, glass stem 3 is set between lamp holder 1 and lamp housing 2, two seal wires 5 are drawn in glass stem 3, seal wire 5 diameter is about 1.2mm, seal wire 5 entirety keeps vertical state, horizontal segment 6 is bent to form at its top end, in seal wire 5 lower end by bending, the spacing of seal wire 5 upper horizontal section 6 is strengthened, and lamp housing 2 is set to spherical;
Step 2, arrange a filament 4, this filament 4 is from left to right in square-wave-shaped, and filament 4 is all in same plane;
Step 3, the horizontal segment 6 of filament 4 two ends respectively at seal wire 5 to be connected, make filament 4 place plane equal to the distance of both sides, front and back lamp housing 2 by adjustment, the left end of filament 4 is equal to the distance of the lamp housing 2 on right side with the right-hand member of filament 4 to the distance of the lamp housing 2 in left side;
Step 4, on the horizontal segment 6 of seal wire 5 spot welding connect a fixed strip, in order to anchored filament 4 position.
Due to the planar separation at the plane at filament 4 place and seal wire 5 main body place is come, solve the defect that light is blocked by support well, thus substantially increase the precision of detection.Lamp housing 2 adopts spherical, and filament 4 is arranged on the centre of lamp housing 2, makes lamp housing 2 all directions overlap at filament 4 place to the reverberation of filament 4, both decreases stray light, and strengthens again the stability of photoluminescence of filament 4; Filament 4 adopts square-wave-shaped, and vertical direction filament length is greater than the length of horizontal direction filament, makes filament not easily sagging, and job stability is strong, long service life.Be welded with fixed strip 7 at the upper surface point of horizontal segment 6, make filament 4 stable connection, difficult drop-off.
