Abstract
The present invention relates to a kind of detection standard lamp of luminous intensity, comprise lamp holder and lamp housing, glass stem stem and filament it is provided with in lamp housing, draw two in described glass stem stem and lead silk, respectively with two, described filament two ends are led silk and are connected, it is characterized in that: described glass stem stem also draws two hollow stings, described in lead silk and be located in hollow sting inside; Described hollow sting entirety is vertical state, and hollow sting top bending forms horizontal section, and silk is connected described filament at horizontal section forward position place with leading; Described filament is from left to right in square wave shape, 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 to the distance of the lamp housing in left side and the right-hand member of filament. The present invention 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 invention belongs to a kind of light fixture, in particular to one detection standard lamp of luminous intensity.
Background technology
In optical radiation measurements, reappearing the original standard of various luminosity and radiometric quantities list such as blackbody furnace, absolute radiometer etc., technology is complicated, takes costliness, should not often remain on working order, is more not easy in real work and uses. It would therefore be desirable to have the position value that original standard is reappeared by corresponding standard lamp is used as secondary standard under copying, 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 specified 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, it is difficult to observe whether the projection and filament itself that filament light-emitting is reflected back overlaps, measuring accuracy is caused detrimentally affect, the centering of filament is also unfavorable.
Summary of the invention
It is an object of the invention to overcome above shortcomings in prior art, and provide a kind of structure simple, can solve light very well is blocked by support, thus improves the light-intensity test standard lamp of accuracy of detection.
The present invention's technical scheme adopted that solves the problem is:
A kind of detection standard lamp of luminous intensity, comprise lamp holder and lamp housing, glass stem stem and filament it is provided with in lamp housing, draw two in described glass stem stem and lead silk, respectively with two, described filament two ends are led silk and are connected, described glass stem stem also draws two hollow stings, described in lead silk and be located in hollow sting inside; Described hollow sting entirety is vertical state, and hollow sting top bending forms horizontal section, and silk is connected described filament at horizontal section forward position place with leading; Described filament is from left to right in square wave shape, 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 to the distance of the lamp housing in left side and the right-hand member of filament.
As preferably, described hollow sting is molybdenum bar 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, solves the defect that light is blocked by support well, thus considerably increases the precision of detection. Lamp housing adopts spherical, and filament is arranged on the centre of lamp housing so that in lamp housing all directions overlaps the reflected light of filament at filament place, had both decreased stray light, and strengthened again the stability of photoluminescence of filament; Filament adopts square wave shape, and vertical direction filament length is greater than the length of horizontal direction filament so that filament is not easily sagging, and job stability is strong, it may also be useful to the life-span is long.

Fig. 2 is the front view of the embodiment of the present invention.
Fig. 3 is the side view 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 detection 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 stem 3 and filament 4 it is provided with in lamp housing 2, draw two in described glass stem stem 3 and lead silk 6, described respectively with two, filament 4 two ends are led silk 6 and are connected, and described glass stem stem 3 also draws two hollow stings 5, described in lead silk 6 to be located in hollow sting 5 inner; Described hollow sting 5 entirety is vertical state, and hollow sting 5 top bending forms horizontal section 7, and silk 6 is connected described filament 4 at horizontal section 7 forward position place with leading; Described filament 4 is from left to right in square wave shape, 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 to the distance of the lamp housing 2 in left side and the right-hand member of filament 4. Described hollow sting 5 is molybdenum bar 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 so that in lamp housing 2 all directions overlaps the reflected light of filament 4 at filament 4 place, had both decreased stray light, and strengthened again the stability of photoluminescence of filament 4; Filament 4 adopts square wave shape, and vertical direction filament length is greater than the length of horizontal direction filament so that filament is not easily sagging, and job stability is strong, it may also be useful to the life-span is long.
