Abstract
The invention relates to a conic standard lamp for detection. The conic standard lamp for detection comprises a lamp holder and a glass shell. A core column and a filament are arranged in the glass shell. Two guide wires are led out from the inner portion of the core column, the two ends of the filament are connected with the two guide wires respectively, the glass shell is of a reversed-conic shape with a circular arc top end face, a square fixing frame is further arranged in the glass shell, the center of the bottom of the fixing frame is connected to the inner portion of the core column through a supporting rod, the lower end of the fixing frame is further fixedly provided with a fixing base, a plurality of molybdenum wire hooks are arranged on the fixing base at intervals side by side, the inner side of the top of the fixing frame is further provided with a plurality of molybdenum wire hooks in a reversed-hanging mode, the molybdenum wire hooks at the upper row and the molybdenum wire hooks at the lower row are arranged in a staggered mode, the distance between every two adjacent molybdenum wire hooks at the upper row or at the lower row ranges from 1.5mm to 2mm, the filament penetrates through the hook portions of the tops of the molybdenum wire hooks in sequence from left to right, and the whole filament is located on the same plane. The convex shell standard lamp for detection has the advantages of being simple in structure, firm in filament fixation and capable of effectively reducing influence by stray light.
Description
Technical field
The present invention relates to a kind of light fixture, particularly a kind of luminous intensity examination criteria light fixture.
Background technology
Luminous intensity examination criteria lamp is for embodying and transmit the value of unit of luminous intensity (candela cd), is the major criterion utensil in optical radiation measurement.Luminous intensity examination criteria lamp is generally made by incandescent lamp or tungsten halogen lamp, in order to make filament become the unique luminous element of luminous intensity examination criteria lamp, should make the stray light of glass cell-shell and other filament holder be reduced to minimum degree.At present typical luminous intensity examination criteria lamp is generally only comprised of bulb and lamp socket, the impact of stray light is larger, and be difficult to be stablized, uniform light intensity value, also some luminous intensity examination criteria lamp is for reducing the impact of stray light, adopt too complicated structure, increased production cost, and filament is fixing insecure, be difficult to into same plane, affected the detection effect of standard lamp.
Summary of the invention
The present invention is directed to deficiency of the prior art, provide a kind of simple in structure, filament fixation, and taper standard light fixture for the detection that can effectively reduce stray light.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals:
Taper standard light fixture for a kind of detection, comprise lamp holder, glass bulb, in glass bulb, be provided with stem stem, filament, in described stem stem, draw two seal wires, the two ends of described filament are connected with two seal wires respectively, described glass bulb is the inverted cone shape that upper surface becomes arc surface, in described glass bulb, be also provided with a square fixed mount, the bottom center of fixed mount is connected in stem stem by support bar, described fixed mount lower end is also fixed with holder, on holder, interval is provided with some molybdenum wire hooks side by side, fixed mount inside top is also hung upside down and is provided with some molybdenum wire hooks, described two rows molybdenum wire hook is staggered, spacing between adjacent two molybdenum wire hooks of upper row or lower row is 1.5mm-2mm, filament from left to right passes the hook portion at each molybdenum wire hook top successively, described filament is all in same plane.
As preferably: the whole height of light fixture is 170mm, and width is 100mm, and the whole height of described filament is 16-20mm, and width is also 16-20mm.Adopt so light fixture and filament size, make the luminous efficiency of filament better, it is more reasonable to design.
As preferably: described holder is made by pottery or glass, and the even blacking of outer surface of pottery and glass.Such structure has effectively reduced the impact of the stray light of holder on light source.
The present invention adopts technique scheme, glass bulb adopts upper surface to become the inverted cone shape of arc surface, make in glass bulb all directions the reflective projection of filament outside glass bulb, both reduced stray light, while having avoided again adopting spherical glass bulb, must guarantee that filament could reduce the difficulty of processing of stray light at glass bulb center, improve qualification rate; Adopt fixed mount to be beneficial to anchored filament, and easily make each segment filament all in the same plane; Adopt two rows molybdenum wire hook, and molybdenum wire hook tool is at regular intervals, after making filament hang on molybdenum wire hook, forms multistage and be close to parallel in line silk; Form a uniform area source of stable luminescence; Improve product quality, for light detects, provide foundation more accurately.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
