Abstract
The utility model relates to a detection spherical 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 has a spherical shape. 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 horizontally arranged fixed seat. A plurality of molybdenum wire hooks are disposed 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, and the distance between two adjacent molybdenum wire hooks in the upper or lower row is 1.5mm to 2mm. 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, and the distance from the plane to a front side of the glass bulb is equal to the distance from the plane to a rear side of the glass bulb. The distance from a left end of the lamp filament to the glass bulb at a left side is equal to the distance from a right end of the lamp filament to the glass bulb at a right side. According to the utility model, the detection spherical 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 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, 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 can effectively reduce the spherical standard lamp of detection of stray light.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
The spherical standard lamp of a kind of detection, 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, 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 horizontally disposed 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 at each molybdenum wire hook top successively, 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: the whole height of described filament is 16-20mm, and width is also 16-20mm.
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 utility model adopts technique scheme, in glass bulb center, the inverted image in all directions is overlaped on filament, has reduced the impact of stray light, adopts square fixed mount to be beneficial to anchored filament, and easily makes 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 each other parallel in line silk; Thereby form a uniform area source of stable luminescence; Improve product quality, for light detects, provide foundation more accurately.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
