Abstract
The utility model discloses an energy saving tungsten wire illuminating lamp, which belongs to the technical field of the electric light source. A conducting wire, a metal supporting frame and a filament are arranged in a glass bulb casing of the utility model, the filament is positioned at the upper end of the metal supporting frame, and the filament is a dual helicoid which is formed by winding a spring type tungsten wire. Because the filament is a dual helicoid, the length of the filament can be shortened, the metal supporting frame used for supporting the filament is reduced, under the condition that the luminous flux is not changed (the illuminating effect is not changed), the power of the lamp bulb is reduced, but the luminous efficiency is higher, and the energy saving effect is obvious.
Description
Technical field:
The utility model relates to the electric light source technology field, especially relates to a kind of common tungsten filament illuminating lamp.
Background technology:
Common tungsten filament illuminating lamp is widely adopted owing to having easy to use, cheap advantage, but, well-knownly be: common tungsten filament illuminating lamp luminous efficiency is low, belong to the high energy consumption product, for a long time, those skilled in the art are trying every possible means to improve the luminous efficiency of common tungsten filament illuminating lamp always.
Existing tungsten filament illuminating lamp, see shown in accompanying drawing 1 and the accompanying drawing 2: the filament 02 in its cell-shell 01 is the tungsten filament of single-screw body shape, and not only filament 02 length is longer, and needs four metallic supports 03 to support, and will improve production cost of products like this; In addition, existing tungsten filament illuminating lamp vacuum degree and fail safe also are still waiting to improve.
The utility model content:
The purpose of this utility model is the weak point that exists at prior art and a kind of energy-saving tungsten filament illuminating lamp is provided that it has characteristics simple in structure, that luminous efficiency is high.
For achieving the above object, be provided with seal wire, metallic support and filament in the glass cell-shell of the present utility model, filament is positioned at the metallic support upper end, and described filament is the double helix by the tungsten filament winding one-tenth of spring-like.
As improvement of the technical scheme, have two getters in the described cell-shell.
As further improvement in the technical proposal, described seal wire is the insurance seal wire.
After adopting technique scheme,, can shorten the length of filament because filament is a double helix, reduce the metallic support of filament supports, under the situation that keeps luminous flux constant (being that illuminating effect is constant), bulb power reduces but luminous efficiency is higher, and energy-saving effect is remarkable.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described further:
Accompanying drawing 1 is existing common tungsten filament illuminating lamp overall structure schematic diagram;
Accompanying drawing 2 is the connection diagram after filament in the accompanying drawing 1 and metallic support amplify;
Accompanying drawing 3 is a structural representation of the present utility model;
Accompanying drawing 4 is the connection diagram after filament in the accompanying drawing 3 and metallic support amplify.
Embodiment:
The following stated for embodying the preferred embodiment of the utility model principle, is not to be used to limit protection range of the present utility model only.
See shown in accompanying drawing 3 and the accompanying drawing 4: fill the inert gas of macromolecule and be provided with seal wire 10, metallic support 20 and filament 30 in its glass cell-shell 100 of energy-saving tungsten filament illuminating lamp of the present utility model (be divided into PZS220V36w, PZS220V55w, PZS220V94w is several), filament 30 is positioned at metallic support 20 upper ends, it is the double helix by the tungsten filament winding one-tenth of spring-like, promptly at first with the single-screw body of the tungsten filament coiled spring-like of linearity, afterwards with the single-screw body again winding become the helicoid of spring-like, thereby constitute double helix filament 30.In this way, not only can shorten the length of filament 30, reduce the quantity (metallic support 20 shown in the figure makes a farfetched comparison the illuminating lamp shown in Fig. 1 and lacked two) of metallic support 20, and under keeping the constant situation of luminous flux (can reach PZS220V40w, the PZS220V60w in the GB/T110681-2004 standard, the normal light flux level of PZS220V100w), reach higher luminous efficiency, reduce simultaneously the power of illuminating lamp again, make illuminating lamp more energy-conservation.
In addition, have two getters 40 in the cell-shell 100,, reduce thermal losses, thereby further improve the luminous efficiency of filament 30 to improve the vacuum degree in the cell-shell 100.In addition, seal wire 10 adopts the insurance seal wire, with the fail safe of further raising illuminating lamp.
