Abstract
The utility model relates to a convex hull standard bulb for detection; the convex hull standard bulb comprises a lamp holder and a glass case; a core pillar and filaments are arranged in the glass case; the glass case is in an inverted cone shape with a top end face being an arc surface; an arc protrusion is arranged in middle of the arc surface, occupies 1/2 to 2/3 of the whole arc surface, and the height of the arc protrusion is 5 to 10mm; a rectangular fixing frame is arranged in the glass case; a bottom center of the fixing frame is connected to the core pillar through a support rod; the bottom of the fixing frame is also fixedly provided with a fixing seat having a plurality of molybdenum wire hooks; the molybdenum wire hooks on an upper row and a lower row are alternately arranged; the filaments penetrate a hook portion of the top of each molybdenum wire hook in sequence from left to right, and are positioned on a same plane surface. The convex hull standard bulb for detection is simple in structure, small in darkened area, the filaments are firmly fixed, and stray light influences can be effectively reduced.
Description
Technical field
The utility model relates to a kind of light fixture, particularly a kind of luminous intensity examination criteria bulb.
Background technology
Luminous intensity examination criteria lamp is the value for embodying and transmit 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 made up 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 the impact that reduces stray light, adopt too complicated structure, increased production cost, and filament is fixing insecure, is difficult to into same plane, affect the detection effect of standard lamp, especially filament oxidation in the time of long-term use, can cause tube face melanism, affects illumination quality.
Summary of the invention
The utility model, for deficiency of the prior art, provides a kind of simple in structure, and melanism region is little, filament fixation, and can effectively reduce the detection convex hull standard lamp of stray light.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
A kind of detection used convex hull standard 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, and the central authorities of arc surface are provided with arch projection, described arch projection accounts for the 1/2-2/3 of whole arc surface, and the height of arch projection is 5-10mm, 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, 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 bulb 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 up of pottery or glass, and the even blacking of outer surface of pottery and glass.Such structure has effectively reduced the stray light of holder to the impact of light source.
The utility model 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, improved qualification rate; And on glass bulb, be provided with arch projection, the melanism of glass bulb is concentrated on to top, concentrate deposition region, described arch projection accounts for the 1/2-2/3 of the whole arc surface in glass bulb top, melanism is more easily collected, make again whole lamp shape more well-balanced, the useful life of having improved bulb simultaneously; 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, provide foundation more accurately for light detects.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
