Abstract
The invention relates to a standard tapered lamp, comprising a lamp base and a glass shell, wherein a stem and a lamp filament are arranged in the glass shell, the glass shell is an inverted cone with an arc surface as the upper end face, a square fixed mount is further arranged in the glass shell, the plane where the fixed mount locates is parallel to one side wall of the glass shell right opposite to the fixed mount, the bottom center of the fixed mount is connected into the stem through a support post, the lower end of the fixed mount is further fixedly provided with a fixed seat, the fixed seat is provided with a plurality of molybdenum wire hooks, the inner side of the top of the fixed mount is further provided with a plurality of molybdenum wire hooks in inverted hanging manner, the upper and lower rows of molybdenum wire hooks are arranged in staggering manner, distance between the two adjacent molybdenum wire hooks in the upper or lower row is 1.5mm-2mm, the lamp filament sequentially penetrates through the hook part of each molybdenum wire hook from the left to right, and the lamp filament is placed in a same plane. According to the standard tapered lamp, the structure is simple, the lamp filament is firmly fixed, and the influence of 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 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, 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 tapered standard light fixture 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 tapered standard light fixture, 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 parallels with a sidewall of its just right glass bulb, 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 of each molybdenum wire hook 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 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 present invention adopts technique scheme, fixed mount is obliquely installed and with glass bulb parallel sidewalls, can reduce the reflection of glass bulb sidewall to the impact of light source, 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; 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.
