Abstract
The invention relates to a conical lamp for detection. The conical lamp for detection comprises a lamp holder and a glass bulb, wherein a core column and a filament are arranged in the glass bulb, the glass bulb is in an inverted cone shape, the upper end face of the glass bulb is a circular arc face, a square fixed frame is further arranged inside the glass bulb, the plane where the fixed frame is located is parallel to one side wall, right facing the fixed frame, of the glass bulb, and the center of the bottom of the fixed frame is connected inside the core column through a supporting rod; the inner wall of the glass bulb is blacked, only a light-transmitting window is formed in the side wall parallel to the fixed frame, and the edge of the light-transmitting window and the edge of the fixed frame coincide; a fixed base is further fixedly arranged at the lower end of the fixed frame, the fixed base is provided with a plurality of molybdenum wire hooks, a plurality of molybdenum wire hooks are also inversely hung on the inner side of the top of the fixed frame, the upper row of the molybdenum wire hooks and the lower row of the molybdenum wire hooks are arranged in a staggered mode, the filament sequentially penetrates through the hook portions of the tops of all the molybdenum wire hooks from left to right, and the filament is located in the same plane. The conical lamp for detection is simple in structure, the filament is fixed firmly, and influences caused by stray light can be effectively reduced.
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 can effectively reduce the detection tapered lamp of stray light.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals:
A kind of detection tapered lamp, 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 plane at described fixed mount place with its over against a sidewall of glass bulb parallel, the bottom center of fixed mount is connected in stem stem by support bar, the blacking of described glass bulb inwall, only on that sidewall paralleling with fixed mount, stay next optical transmission window, the edge of optical transmission window and the edge of fixed mount coincide, described fixed mount lower end is also fixed with holder, on holder, be provided with some molybdenum wire hooks, 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 decrease the impact of the stray light that reflects of holder on light source.
The present invention adopts technique scheme, fixed mount is obliquely installed, can reduce the impact of the reflection of glass bulb sidewall on light source, glass bulb blacking is only stayed to next optical transmission window, and the coincident of optical transmission window and fixed mount, the blacking that square fixed mount is glass bulb provides reference line, makes glass bulb blacking easier, border is more accurate, and difficulty of processing reduces; And fixed mount is beneficial to anchored filament, and easily make each segment filament all in the same plane; The setting of square fixed mount has two excellent effects, 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 is close to parallel in line silk; Form a uniform area source of stable luminescence; Improve product quality, for light detects, provide foundation more accurately.
