Abstract
The invention relates to a luminous intensity detection standard lamp. The luminous intensity detection standard lamp comprises a lamp holder and a glass bulb, wherein a core column and filaments are arranged in the glass bulb, the upper end face of the glass bulb is a circular-arc-shaped surface, the glass bulb is of an inverted-cone shape, the inner wall of the glass bulb is blackened, only one rectangular or square light-pervious window is formed in the portion, arranged in front of the plane where the filaments are located, of the glass bulb, a fixing base is connected between two guide wires, a plurality of molybdenum wire hook sets are arranged on the fixing base, each molybdenum wire hook set 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 of each molybdenum wire hook set are arranged on the same vertical line, the filaments penetrate through the hook portions arranged on the tops of the molybdenum wire hooks in sequence from left to right in a square wave shape mode, the filaments are arranged on the same plane, and the filaments are arranged in the center of the light-pervious window. According to the luminous intensity detection standard lamp, adjustment of the filaments is simplified, and only the situation that the filaments are located in the center of the light-pervious window needs to be ensured; due to the facts that the filaments are of a square-wave shape, and the length of the portion, in the perpendicular direction, of each filament is larger than that of the portion, in the horizontal direction, of the filament, the filaments cannot easily fall off, working stability is good, 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 light fixture.
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 luminous intensity examination criteria light fixture 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 luminous intensity examination criteria light fixture, 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, the inwall blacking of glass bulb, only on the glass bulb in the dead ahead of filament plane of living in, be provided with a rectangle or foursquare optical transmission window, the length of described optical transmission window is 18-20mm, width is 18mm, 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, described filament is positioned at the centre of optical transmission window.
As preferably: described holder is made by pottery or glass, and the outer surface of pottery and glass is equal and blacking.Such structure decrease the impact of the stray light that reflects of holder on light source.
The present invention adopts technique scheme, and glass bulb adopts upper surface to become the inverted cone shape of arc surface, and by glass bulb blacking, only stays next optical transmission window, has reduced catoptrical impact in glass bulb all directions; Filament adjustment is simplified, as long as guarantee that filament is in optical transmission window central authorities; 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.
