Abstract
The invention relates to a luminous intensity standard lamp for detection. The luminous intensity standard lamp for detection comprises a lamp cap and a lamp shell, a glass stem and a lamp filament are arranged in the lamp shell, two conducting wires are led out of the glass stem, and two ends of the lamp filament are connected with the two conducting wires respectively. The luminous intensity standard lamp for detection is characterized in that two hollow supports are led out of the glass stem and are integrally vertical, the conducting wires are arranged inside the hollow supports penetratingly, top ends of the hollow supports are bent to form horizontal segments, the lamp filament is connected with the conducting wires at the front edge positions of the horizontal segments, the lamp filament is in a square wave shape from left to right and positioned in the same plane, the distance between the plane and a front shell body is as same as that between the plane and a rear shell body, and the distance between the left end of the lamp filament and a left lamp shell body is as same as that between the right end of the lamp filament and a right lamp shell body. The luminous intensity standard lamp for detection has the advantages that the lamp filament and the supports are arranged in different planes and the defect that light is shielded by the supports is well overcome, so that detection precision is enhanced greatly.
Description
Technical field
The invention belongs to a kind of light fixture, particularly one detection 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 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 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 detection standard lamp of luminous intensity, comprise lamp holder and lamp housing, glass stem and filament is provided with in lamp housing, two seal wires are drawn in described glass stem, respectively with two, described filament two ends seal wire is connected, 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 bending forms horizontal segment, and described filament is connected at horizontal segment forward position place with seal wire; 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 spheroidal.
The present invention compared with prior art, has the following advantages and effect: filament and Bracket setting in Different Plane, solve the defect that light is blocked by support well, 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.
