Abstract
The utility model relates to a detection conical standard lamp comprising a lamp holder and a glass bulb. A stem and a lamp filament are disposed in the glass bulb. The glass bulb is in the shape of an inverted cone with an arc upper end face. A square fixed fame is further disposed in the glass bulb. The center at the bottom of the fixed frame is connected into the stem via a support rod. The lower end of the fixed frame is further fixedly provided with a fixed seat. A plurality of molybdenum wire hooks are spaced and disposed side by side on the fixed seat. A plurality of molybdenum wire hooks also hang upside down on the inner side at the top of the fixed frame. The upper and lower rows of the molybdenum wire hooks are in staggered arrangement. The lamp filament penetrates through the hook portions at the top of the molybdenum wire hooks sequentially from left to right. The entire lamp filament is located on the same plane. According to the utility model, the detection conical standard lamp is simple in structure, the lamp filament is fixed firmly and the effects of stray light 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 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 utility model, for deficiency of the prior art, provides 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 utility model is solved by following technical proposals:
A kind of detection with taper 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 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 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 ensure 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.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
