Abstract
A kind of light-intensity test standard lamp, comprise lamp holder and lamp housing, glass stem and filament is provided with in lamp housing, draw two seal wires in described glass stem, respectively with two, described filament two ends seal wire is connected, and described seal wire entirety is vertical state, guidewire tip is bent to form horizontal segment, horizontal segment forward position continues to be bent to form vertical section, and described filament is connected with the vertical section of seal wire, and the whole height of filament is greater than the length of vertical section; Described filament is from left to right in square-wave-shaped, and filament is all in same plane, and this plane is equal to the distance of both sides, front and back lamp housing, and the left end of described 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.The utility model in Different Plane, solves filament and Bracket setting well the defect that light is blocked by support, thus considerably increases the precision of detection.
Description
Technical field
The utility model belongs to a kind of light fixture, particularly a kind of light-intensity test standard lamp.
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.
Utility model content
The purpose of this utility model is to overcome above shortcomings in prior art, and provides a kind of structure simple, and can solve light is very well blocked by support, thus improves the light-intensity test standard lamp of accuracy of detection.
The technical scheme in the invention for solving the above technical problem is:
A kind of light-intensity test standard lamp, comprise lamp holder and lamp housing, glass stem and filament is provided with in lamp housing, draw two seal wires in described glass stem, respectively with two, described filament two ends seal wire is connected, and described seal wire entirety is vertical state, guidewire tip is bent to form horizontal segment, horizontal segment forward position continues to be bent to form vertical section, and described filament is connected with the vertical section of seal wire, and the whole height of filament is greater than the length of vertical section; Described filament is from left to right in square-wave-shaped, and filament is all in same plane, and this plane is equal to the distance of both sides, front and back lamp housing, and the left end of described 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.
In order to ensure that filament is stablized, difficult drop-off, as preferably, described vertical section surface spot welding is connected with the fixed strip for anchored filament.Be clipped in filament one end between fixed strip and vertical section, spot welding stress is little, easily adjustment filament evenness.
As preferably, described lamp housing is spheroidal.
The utility model 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.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the front view of the utility model embodiment.
Fig. 3 is the lateral plan of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing, also by embodiment, the utility model is described in further detail, and following examples are that the utility model is not limited to following examples to explanation of the present utility model.
Light-intensity test standard lamp as shown in Figure 1, Figure 2 and Figure 3, comprise lamp holder 1 and lamp housing 2, described lamp housing 2 is spherical in shape, is provided with glass stem 3 and filament 4 in lamp housing 2, draw two seal wires 5 in described glass stem 3, respectively with two seal wires 5 in described filament 4 two ends are connected.Glass stem 3 is arranged on the centre that lamp holder 1 is connected with lamp housing 2, and the both sides of glass stem 3 draw two seal wires 5 respectively, and the diameter of seal wire 5 is about 1.2mm, thus make it to have certain stability.Seal wire 5 has five sections, and first paragraph is the vertical median plane that the vertical section 51 of the first vertical section 51, first is positioned at lamp housing 2; The second segment of seal wire 5 is bending segment 52, makes seal wire 5 leave the vertical median plane of lamp housing 2 by bending; 3rd section of the second vertical section 53 for leaving the vertical median plane of lamp housing; 4th section is horizontal segment 6; 5th section is vertical section 7, and vertical section 7 is positioned at the vertical median plane of lamp housing 4.The whole height of filament 4 is greater than the length of vertical section 7, and filament 4 can not be blocked by vertical section 7.
Filament 4 is connected with a certain position of seal wire 5 in vertical section 7, makes the left end of filament 4 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.Filament 4 is all in same plane, and this plane is equal to the distance of both sides, front and back lamp housing 2.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.
