Abstract
The invention relates to a standard bulb for detection. The standard bulb comprises a lamp cap and a glass bulb body. A stem and lamp filaments are arranged in the glass bulb body. The upper end face of the glass bulb body is of an arc-face back taper shape. The center of the arc face is provided with an arched protrusion. The arched protrusion accounts for one half to two thirds of the arc face. The height of the arched protrusion is 3-8cm. A fixing base is connected between the two guide wires and provided with a plurality of molybdenum wire hook sets. Each molybdenum wire hook set comprises a high molybdenum wire hook and a low molybdenum wire hook. The hook portion of each high molybdenum wire hook and the hook portion of each low molybdenum wire hook are located on the same vertical line. The lamp filaments sequentially penetrate through the hook portions of the tops of the molybdenum wire hooks from left to right according to a square wave shape, and are arranged on the same plane. The arched protrusion is arranged on the glass bulb body, the blackening phenomenon of the glass bulb body is concentrated on the top, the deposition area is concentrated, the area is reduced, and the service life of the lamp bulb is prolonged.
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 use for a long time filament oxidation, can cause tube face melanism, affect 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, and can effectively reduce the detection standard lamp 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 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 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, 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, improve 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 invention.
Fig. 2 is the structural representation of molybdenum wire hook group of the present invention.
Fig. 3 is the structural representation of filament of the present invention.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is described in further detail:
A kind of 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 whole one-tenth 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 top successively according to square-wave-shaped, and 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 by pottery or glass, and the even blacking of the outer surface of pottery or glass.
