Description

The single-ended tungsten halogen lamp of cylindrical coiled filament structure

The utility model relates to a kind of single-ended tungsten halogen lamp of cylindrical coiled filament structure.

The filamentray structure of the optically focused tungsten halogen lamp of video display stage use at present mainly contains double helix, triple helical and single face helical structure, because the double-spiral structure luminous element is elongated, and only suitable ellipsoid light fixture; Triple-helix structure exists the shortcoming that tangible filament blocks mutually, and the light-emitting area of monoplane helical structure is bigger, and service efficiency is lower in light fixture; Because above-mentioned filamentray structure is not suitable for level and lights, therefore in a part of light fixture, can't use; Above-mentioned filamentray structure makes lamp design bigger, has increased raw materials consumption; The patent No. is 96209328.9, and name is called a kind of single-ended tungsten halogen lamp of biplane coiled filament structure, and situation improves to some extent, but still exists that lower, the unsuitable level of efficient is used and defective such as material consumption is bigger.

The purpose of this utility model be design for overcoming above-mentioned weak point that a kind of each section of filament is parallel to along the face of cylinder that bus is arranged, luminous element is more near the single-ended tungsten halogen lamp of the cylindrical coiled filament structure of ideal point light source.

The utility model content: a kind of single-ended tungsten halogen lamp of cylindrical coiled filament structure, comprise transparent lamp housing, power supply lead wire, molybdenum foil, filament and the bracing frame of forming by bracing frame hook, pole and upper and lower glass post, be filled with the inert gas of halide in the lamp housing, two power supply lead wires are introduced by the lamp housing bottom, the two ends and the power supply lead wire of filament are electrically connected, filament be is characterized in that by bracing frame hook supporting: form the isometric taenidium of the multistage of filament be arranged as one cylindrical.The hop count of described taenidium is made as four sections or six sections or eight sections or ten sections.

The utlity model has following good effect:

1. because each segment filament is parallel to the bus arrangement along the face of cylinder, light is concentrated, more near the ideal point light source.

2. the illuminance of cylindrical coiled filament structure can reach 13000LX for the 220V electric current during for 8.93A at voltage, has increased substantially illuminance.

3. the volume of cylindrical coiled filament structure is little, and compact conformation has reduced raw materials consumption, can use in any direction under the supporting of bracing frame.

Description of drawings:

Fig. 1 is the utility model front view;

Fig. 2 is the end view of Fig. 1;

Fig. 3 is the schematic perspective view of filament;

Fig. 4 is a kind of connection diagram of each section of filament (overlooking);

Fig. 5 is the another kind of connection diagram of each section of filament (overlooking).

Further specify the utility model below in conjunction with drawings and Examples.

Please referring to Fig. 1, Fig. 2, the lamp housing 6 of transparent sealing is cylindrical, fill nitrogen 3 in the lamp housing to contain hydrogen bromide, the lamp housing bottom is provided with flat 11 on press seal folder, power supply lead wire enters in the lamp housing by the flat portion of folder of lamp housing bottom, and power supply lead wire comprises molybdenum rod 10, the molybdenum foil 9 as outer lead and is used as the tungsten filament 8 of lead; Bracing frame is by being the last glass post 2 of material and following glass post 12 with the quartz glass and being that the pole 5 and the upper and lower bracing frame hook 7 of material formed with tungsten filament; The lamp housing top is provided with blast pipe sealed-off mouth 4, filament 1 (tungsten filament) is supported by upper and lower bracing frame hook, the two ends of filament are electrically connected at close glass post place down and lead, filament can be made up of four sections or six sections or eight sections or ten sections isometric taenidiums, and taenidium is arranged in a cylindrical surface (Fig. 3) along the axis direction of columniform lamp housing parallel (bus that promptly is parallel to cylinder); The filament that present embodiment selects for use eight sections taenidiums to form, the connection order of these eight sections taenidiums is a kind of to be 1a, 1b, 1c, 1d, 1e, 1f, 1g, 1h (Fig. 3, Fig. 4), also can be by another kind connection order, i.e. 1a, 1b, 1c, 1f, 1g, 1h, 1e, 1d (Fig. 5);

The illuminance of the utility model and single silk lamp and double silk lamp contrasts as following table:

	Voltage (V)	Electric current (A)	Power (W)	Illuminance (10M distance, 3M diameter spot) (LX)
Single silk lamp	220	9.10	2002	9000
Double silk lamp	220	9.05	1991	7800
The cylindrical wire lamp	220	8.99	1978	13000
