Abstract
The utility model relates to a detecting standard bulb comprising a lamp cap and a glass casing. A core pillar and a filament are disposed in the glass casing. The top end face of the glass casing is in an inverted conical shape with an arc surface. An arched protrusion is disposed on the center of the arc surface and occupies a half to two thirds of the whole arc surface. The height of the arched protrusion is from 3 to 8 cm. Two guide wires are connected via a fixed seat on which a plurality of molybdenum wire hook groups are disposed. Each molybdenum wire hook group comprises a high molybdenum wire hook and a low molybdenum wire hook. The hook portion of the high molybdenum wire hook and the hook portion of the low molybdenum wire hook are arranged in a same vertical line. The filament successively passes through the hook portion on the top of each molybdenum wire hook from left to right in a square wave manner, and is arranged in a same plane. The arched protrusion disposed on the glass casing such that a blackening phenomenon is aggregated on the top of the glass casing, a deposition area is aggregated, and area is decreased. Therefore, the service life of the bulb is prolonged.
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 use for a long time filament oxidation, can cause tube face melanism, affect 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, and can effectively reduce the detection 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 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 3-8cm, between described two seal wires, be connected with a holder, on holder, be provided with some molybdenum wire hook groups, each molybdenum wire hook group comprises two molybdenum wire hooks of height, the hook portion of two molybdenum wire hooks of described height is in same vertical curve, filament from left to right passes the hook portion at each molybdenum wire hook top successively according to square-wave-shaped, described filament is all in same plane.
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 be provided with arch projection on glass bulb, the melanism of glass bulb is concentrated on to top, concentrate deposition region, area reducing, the useful life of having improved bulb; Filament adopts square-wave-shaped, and vertical direction filament length is greater than the length of horizontal direction filament, filament is difficult for sagging, and job stability is strong, long service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of molybdenum wire hook group of the present utility model.
Fig. 3 is the structural representation of filament of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail:
One detection standard lamp as shown in Figure 1, Figure 2 and Figure 3, comprise lamp holder 1, glass bulb 4, in glass bulb 4, be provided with stem stem 2, filament 6, in described stem stem 2, draw two seal wires 7, the two ends of described filament 6 are connected with two seal wires 7 respectively, when lamp holder 1 under, glass bulb 4 is when upper, light fixture entirety becomes rounding vertebra shape or inverted round stage shape, and the upper surface of glass bulb 4 is arc surface; And the central authorities of arc surface are provided with arch projection 9, described arch projection 9 accounts for the 1/2-2/3 of whole arc surface, and the height of arch projection 9 is 3-8cm, between described two seal wires 7, be connected with a holder 3, on holder 3, be provided with some molybdenum wire hook groups, each molybdenum wire hook group comprises two molybdenum wire hooks 5 of height, the hook portion 8 of two molybdenum wire hooks 5 of described height is in same vertical curve, filament 6 from left to right passes the hook portion 8 at each molybdenum wire hook 5 tops successively according to square-wave-shaped, described filament 6 is all in same plane.Filament adopts square-wave-shaped, and vertical direction filament length is greater than the length of horizontal direction filament, filament is difficult for sagging, and job stability is strong, long service life.Described holder 3 is made up of pottery or glass, and the even blacking of the outer surface of pottery or glass.
