Abstract
The invention relates to a standard lamp for detection. The standard lamp comprises a lamp cap and a glass bulb. A stem and lamp filaments are arranged in the glass bulb. The glass bulb is spherical. A fixing base is connected between 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 distance from the plane to the front side of the glass bulb is equal to the distance from the plane to the rear side of the glass bulb. The distance from the left ends of the lamp filaments to the left side of the glass bulb is equal to the distance from the right ends of the lamp filaments to the right side of the glass bulb. According to the standard lamp, influence of stray light is reduced, and the light-emitting stability of the lamp filaments is improved. The lamp filaments are of square wave shapes, the length in the vertical direction of the lamp filaments is larger than that in the horizontal direction of the lamp filaments, and therefore the lamp filaments do not droop easily, the work stability is high, and the service life is long.
Description
Technical field
The present invention relates to a kind of light fixture, particularly a kind of luminous intensity examination criteria lamp.
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.
Summary of the invention
The present invention is directed to deficiency of the prior art, provide a kind of simple in structure, 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 globulate, 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, this plane equates to the distance of both sides, front and back glass bulb, the distance of the left end of described filament to the distance of glass bulb in left side and the right-hand member of filament to the glass bulb on right side equates.
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 spherical, and filament is arranged on to the centre of glass bulb, makes in glass bulb all directions, the reverberation of filament to be overlapped at filament place, has both reduced stray light, has strengthened again the stability of photoluminescence of filament; 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:
As Fig. 1, a kind of detection standard lamp shown in Fig. 2 and Fig. 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, described glass bulb 4 globulates, 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, filament 6 adopts square-wave-shaped, vertical direction filament length is greater than the length of horizontal direction filament, filament 6 is difficult for sagging, job stability is strong, long service life.Described filament 6 is all in same plane, this plane equates to the distance of both sides, front and back glass bulb 4, the distance of the left end of described filament 6 to the distance of glass bulb 4 in left side and the right-hand member of filament 6 to the glass bulb 4 on right side equate, the height of described filament 6 in glass bulb 4 is identical with the radius of glass bulb 4.Described holder 3 is made by pottery or glass, and the even blacking of outer surface of pottery and glass.
