Abstract
The invention relates to a luminous intensity detection convex shell standard lamp bulb. The luminous intensity detection convex shell standard lamp bulb comprises a lamp holder and a glass shell, wherein a core column and lamp filament are arranged in the glass shell; the glass shell adopts an inverted cone structure with an arc-shaped upper end surface; an arch-shaped bump is arranged in the center of the arc-shaped surface and accounts for 1/2 to 2/3 of the overall arc-shaped surface; a square fixed frame is also arranged in the glass shell; the center of the bottom part of the fixed frame is connected to the inside of the core column through a support rod; the inner wall of the glass shell is blackened, only a light-transmitting window is reserved in the inner wall of the glass shell; the edge of the light-transmitting window overlaps with the edge of the fixed frame; a fixed seat is also fixedly arranged at the lower end of the fixed frame; a plurality of molybdenum wire hooks are arranged on the fixed seat; a plurality of molybdenum wire hooks are also hung upside down on the inner side of the top part of the fixed frame; the molybdenum wire hooks in the upper row and the lower row are arranged in a staggered way; the lamp filament penetrates through the hook parts of the molybdenum wire hooks in sequence from left to right; the lamp filament is positioned on the same plane. The luminous intensity detection convex shell standard lamp bulb is simple in structure; a blackening area is small; the lamp filament is fixed firmly; the influence caused by stray light can be reduced effectively.
Description
Technical field
The present invention relates to a kind of light fixture, particularly a kind of luminous intensity examination criteria bulb.
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.Especially filament oxidation when long-term use, can cause tube face melanism, affects illumination quality.
Summary of the invention
The present invention is directed to deficiency of the prior art, provide a kind of simple in structure, melanism region is little, filament fixation, and the luminous intensity that can effectively reduce stray light detects convex hull standard lamp.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals:
A kind of luminous intensity detects 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, the blacking of described glass bulb inwall, only 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 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 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, and glass bulb adopts the inverted cone shape of upper surface one-tenth arc surface, and by glass bulb blacking, only stay next optical transmission window, reduced catoptrical impact in glass bulb all directions, filament adjustment is simplified, as long as guarantee that filament is in optical transmission window central authorities; 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 whole arc surface, melanism is more easily collected, make again whole lamp shape more well-balanced, the useful life of having improved bulb simultaneously; And fixed mount is 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.
