Abstract
The utility model relates to a luminous intensity detection 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. The inner wall of the glass bulb is blackened, and only a rectangular or square light transmitting window is disposed in the glass bulb and right in front of a plane where the lamp filament is positioned. The light transmitting window has a length of 18-20mm, and a width of 18mm. A fixed seat is connected between two conducting wires. A plurality of molybdenum wire hook groups are disposed on the fixed seat. Each molybdenum wire hook group comprises a higher molybdenum wire hook and a lower molybdenum wire hook. The hook portions of the higher and lower molybdenum wire hooks are located on the same vertical line. The lamp filament penetrates through the hook portions at the top of the molybdenum wire hooks sequentially from left to right according to the shape of a square wave. The entire lamp filament is located on the same plane and right at the center of the light transmitting window. According to the utility model, effects of reflecting light of the glass bulb in different directions are reduced; and the adjustment of the lamp filament becomes easier simply by ensuring that the lamp filament is located at the center of the light transmitting window, and the machining difficulty that an original lamp filament must be at the center of the glass bulb is 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.
Summary of the invention
The utility model, for deficiency of the prior art, provides a kind of simple in structure, and can effectively reduce the luminous intensity examination criteria lamp of stray light.
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 examination criteria 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, 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, and 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 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, and glass bulb adopts spherical, and by glass bulb blacking, only stays next optical transmission window, has reduced catoptrical impact in glass bulb all directions; The adjustment of filament is also simpler, as long as guarantee that filament is in optical transmission window central authorities, having reduced original filament must be at the difficulty of processing of glass bulb 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.
