Abstract
The present invention relates to a kind of standard lamp of luminous intensity, including lamp holder and lamp housing, glass stem and filament it is provided with in lamp housing, two seal wires are drawn in described glass stem, respectively with two, described filament two ends seal wire connects, described glass stem also draws two hollow stings, and described seal wire is located in inside hollow sting; Described hollow sting is state generally vertically, and hollow sting top is first bent to form horizontal segment, is bent to form vertical section in horizontal segment forward position, and on hollow sting top, vertical section place is connected described filament with seal wire, and the whole height of filament is more than the length of vertical section; Described filament is from left to right in square-wave-shaped, and filament is 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 with the distance of the lamp housing of the right-hand member of filament to right side to the distance of the lamp housing in left side. The present invention is arranged on filament and support in Different Plane, solves the defect that light is blocked by support, adds the precision of detection.
Description
Technical field
The invention belongs to a kind of light fixture, particularly to a kind of standard lamp of luminous intensity.
Background technology
In optical radiation measurements, reappear primary standard such as blackbody furnace, the absolute radiometer etc. of various luminosity and radiometric quantities list, technical sophistication, take costliness, duty should not be always maintained at, be more not easy in real work and use. It would therefore be desirable to have the position value that primary standard is reappeared by corresponding standard lamp is used as secondary standard under replicating, transmit its value kept 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 more than filament height, and stent diameter is much larger than filament diameter, when detection, 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, certainty of measurement is had undesirable effect, 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 simple in construction, can solve light very well is blocked by support, thus improving the light-intensity test standard lamp of accuracy of detection.
This invention address that the problems referred to above be the technical scheme is that
A kind of standard lamp of luminous intensity, including 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 connects, and described glass stem also draws two hollow stings, and described seal wire is located in inside hollow sting; Described hollow sting is state generally vertically, and hollow sting top is first bent to form horizontal segment, is bent to form vertical section in horizontal segment forward position, and on hollow sting top, vertical section place is connected described filament with seal wire, and the whole height of filament is more than the length of vertical section; Described filament is from left to right in square-wave-shaped, and filament is 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 with the distance of the lamp housing of the right-hand member of filament to right side 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 is 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 increasing 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 reflection light of filament at filament place, had both decreased stray light, and strengthened again the stability of photoluminescence of filament; Filament adopts square-wave-shaped, and vertical direction filament length is more than the length of horizontal direction filament so that filament is 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.
Detailed description of the invention
Below in conjunction with accompanying drawing and by embodiment, the present invention is described in further detail, and following example are explanation of the invention and the invention is not limited in following example.
A kind of standard lamp of luminous intensity as shown in Figure 1, Figure 2 and Figure 3, including lamp holder 1 and lamp housing 2, described lamp housing 2 is spherical in shape, glass stem 3 and filament 4 it 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 connect, it is characterised in that: described glass stem 3 also draws two hollow stings 5, and it is internal that described seal wire 6 is located in hollow sting 5; Described hollow sting 5 is state generally vertically, 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 more than the length of vertical section 8; Described filament 4 is from left to right in square-wave-shaped, and filament 4 is 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 with the distance of the lamp housing 2 of the right-hand member of filament 4 to right side 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 being arranged in Different Plane, solving the defect that light is blocked by support well, thus considerably increasing 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 reflection 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-shaped, and vertical direction filament length is more than the length of horizontal direction filament so that filament is not easily sagging, and job stability is strong, long service life.
