Abstract
The invention relates to a luminous-intensity standard lamp. The luminous-intensity standard lamp comprises a lamp holder and a lampshell, a glass stem and a filament are arranged in the lampshell, two leads are led out of the glass stem, two ends of the filament are connected with the leads respectively, two hollow supports are led out of the glass stem, and the leads are penetratingly arranged in the hollow support, the hollow supports are integrally vertical, the top ends of the hollow supports are bent to be horizontal sections firstly, the front edges of the horizontal sections are bent to form vertical sections, the filament and the leads are connected at the vertical sections of the top ends of the hollow supports, and the integral height of the filament is larger than the length of the vertical sections; the filament is in the shape of square waves from left to right and on the same plane, the distance from the plane to the front side is equal to the distance from the plane to the rear side, and the distance from the left end of the filament to the lampshell on the left side is equal to the distance from the right end of the filament to the lampshell on the right side. The filament and the support are arranged on different planes, the defect that light is shaded by the support is overcome, and detection accuracy is improved.
Description
Technical field
The invention belongs to a kind of light fixture, particularly a kind of standard lamp of luminous intensity.
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 from the side, support height is greater than filament height, and stent diameter is much larger than filament diameter, when detecting, whether, 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 and 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 structure simple, can solve light is very well blocked by support, thus improves the light-intensity test standard lamp of accuracy of detection.
The present invention's adopted technical scheme that solves the problem is:
A kind of standard lamp of luminous intensity, comprises lamp holder and lamp housing, is provided with glass stem and filament in lamp housing, two seal wires are drawn in described glass stem, respectively with two, described filament two ends seal wire is connected, and described glass stem also draws two hollow stings, and described seal wire is located in hollow sting inside; Described hollow sting entirety is vertical state, and hollow sting top is first bent to form horizontal segment, is bent to form vertical section in horizontal segment forward position, and vertical section place is connected on hollow sting top for described filament and 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.
As preferably, described hollow sting is molybdenum rod support.
As preferably, described lamp housing is spherical in shape.
The present invention compared with prior art, have the following advantages and effect: filament and support are integrally provided in Different Plane, especially the vertical segment length in hollow sting top is much smaller than the design of the vertical length of filament, less to greatest extent support blocking filament, thus considerably increase 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.

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.
A kind of standard lamp of luminous intensity 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, glass stem 3 and filament 4 is provided with in lamp housing 2, two seal wires 6 are drawn in described glass stem 3, respectively with two seal wires 6 in described filament 4 two ends are connected, and it is characterized in that: described glass stem 3 also draws two hollow stings 5, and it is inner that described seal wire 6 is located in hollow sting 5; Described hollow sting 5 entirety is vertical state, hollow sting 5 top is first bent to form horizontal segment 7, continue to be bent to form vertical section 8 in horizontal segment 7 forward position, described filament 4 is connected at vertical section 8 place, hollow sting 5 top with seal wire 6, and the whole height of filament 4 is greater than the length of vertical section 8; Described filament 4 is from left to right in square-wave-shaped, and filament 4 is all in same plane, and this plane is equal to the distance of both sides, front and back lamp housing 2, and the left end of described 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.Described hollow sting 5 is molybdenum rod support.Filament 4 and hollow sting 5 are arranged in Different Plane, solve the defect that light is blocked by support well, thus considerably 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.
