Abstract
The utility model relates to a luminous intensity 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 inner wall of the glass bulb is blackened, and only a light transmitting window is left. The edge of the light transmitting window coincides with the edge of the fixed frame. The lower end of the fixed frame is further fixedly provided with a 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. According to the utility model, the luminous intensity 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 the luminous intensity that can effectively reduce stray light detects spherical standard lamp.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
A kind of luminous intensity detects spherical 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, 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, the blacking of described glass bulb inwall, only stay next optical transmission window, the edge of optical transmission window and the edge of fixed mount coincide, described fixed mount lower end is also fixed with 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.
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, by glass bulb blacking, only stay next optical transmission window, and the coincident of optical transmission window and fixed mount, the blacking that square fixed mount is glass bulb provides reference line, makes glass bulb blacking easier, and border is more accurate, only need be along the edge blacking of square fixed mount, difficulty of processing reduces; And fixed mount is beneficial to anchored filament, and easily make each segment filament all in the same plane; Adopt two rows molybdenum wire hook, and between 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, for light detects, provide foundation more accurately.
