CN2247871Y - Single end tungsten-halogen lamp with double plane spiral filament structure - Google Patents

Abstract

The utility model relates to a single-end tungsten-halogen lamp with a double-plane spiral filament structure, belonging to the technical field of electric light sources. The filaments of the lamp are two identical rectangular planes which are formed by the fact that a plurality of equal-length spiral threads are arranged in parallel, the two rectangular planes are mutually parallel, and an orthogonal hexahedron frame is formed. The lamp, which can usually be used as a focus lamp on movie and television stages, can completely replace an existing single-end halogen-tungsten lamp with a three-plane spiral filament structure and an existing single-end halogen-tungsten lamp with a single-plane spiral filament structure. In addition, a luminous body is near to a spot light source, and thus, the utility model has the advantages of high luminous efficiency, good shock and vibration resistance performance, ignition of any direction, small volume, etc.

Description

A kind of single-ended tungsten halogen lamp of biplane coiled filament structure

The utility model relates to the electric light source technology field, particularly about a kind of single-ended tungsten halogen lamp of novel filamentray structure.

The utility model usually can be as the optically focused tungsten halogen lamp of video display stage.

The filamentray structure of the optically focused tungsten halogen lamp that present video display stage is used mainly contains double helix, triple helical and monoplane helical structure.Double-spiral structure is elongated owing to luminous element, only suitable ellipsoid light fixture; The shortcoming that triple-helix structure exists tangible filament to block mutually; The monoplane helical structure is because light-emitting area is bigger, and service efficiency is lower in light fixture, and is horizontally lighted owing to being not suitable for, and can't use in a part of light fixture, because lamp housing is bigger, increased raw-material consumption.Have a kind of single-ended tungsten halogen lamp of biplane coiled filament structure in the market, its two parallel rectangle planes forming filament stagger mutually, and the hexahedron framework of formation is nonopiate, the poor-performing of the shock-resistant vibrations of single-ended tungsten halogen lamp of this structure.

The purpose of this utility model is to design a kind of luminous element more near the ideal point light source, the luminous efficiency height, and shock-resistant vibrations performance is good, but the single-ended tungsten halogen lamp of a kind of biplane coiled filament structure of any direction burning-point.This lamp can substitute the single-ended tungsten halogen lamp of present widely used triple helical and monoplane coiled filament structure fully, is adapted at using in the multiple light fixture; The lamp housing size obviously reduces than the lamp of monoplane coiled filament structure, thereby raw-material consumption obviously reduces.

The utility model is achieved in that to fill in a vacuum-packed transparent lamp case and contains halid inert gas, the bracing frame of forming by several parts of packing into, two power supply lead wires are introduced in the lamp housing by the same end of lamp housing wall, a filament is fixed on the bracing frame and the two ends and the power supply lead wire of filament is electrically connected.Of the present utility model being characterised in that: filament is arranged in parallel by the multistage taenidium and forms, the parallel spiral silk of multistage of forming filament is arranged in two identical rectangle planes, parallel spiral two identical rectangle planes that are arranged in of multistage of forming filament are parallel to each other, and constitute the hexahedron framework of a quadrature.This section described this lamp has been finished described purpose the last period.

Below in conjunction with accompanying drawing an embodiment of the present utility model is explained in detail.In the accompanying drawings,

Fig. 1 represents the front view of an embodiment;

The embodiment of Fig. 2 presentation graphs 1 expression revolves the end view that turn 90 degrees;

Fig. 3 represents the three-dimensional structure diagram of filament 1.

Present embodiment has a columniform quartz glass lamp housing 2, and it is vacuum-packed, has wherein filled the nitrogen 3 that contains hydrogen bromide; Lamp housing 2 bottoms have a press seal to press from both sides flat part 4, and by it, power supply lead wire is introduced in the lamp housing 2, and power supply lead wire comprises outer lead (molybdenum rod) 5, molybdenum foil 6 and lead (tungsten filament) 7; Bracing frame by last glass post (quartz glass) 8, down glass post (quartz glass) 9, side rod (tungsten filament) 10 and up and down bracing frame hook (tungsten filament) 11 form; A blast pipe sealed-off mouth 12 is arranged at lamp housing 2 tops; Filament (tungsten filament) 1 is fixed on the bracing frame by bracing frame hook 11 up and down; The two ends of filament 1 are electrically connected at close glass post 9 places down and lead 7.Filament 1 is made up of eight sections isometric taenidiums, and taenidium is arranged in parallel into two rectangle planes that are parallel to each other along the axis direction of cylindrical lamp housing 2, and each rectangle plane is made up of four sections taenidiums.Each four sections taenidium on former and later two planes are corresponding one by one in Fig. 1, coincide mutually.As shown in Figure 3, eight of filament 1 sections taenidiums are that order by 1a, 1b, 1c, 1d, 1e, 1f, 1g, 1h is communicated with.

The voltage of present embodiment is 220V, and power has 300W, 500W, 750W, 1000W, 2000W etc.Lamp with 1000W is an example, and the lamp housing external diameter is 19mm, and the filament total length is 1460mm, and silk heavily is 102mg/200mm.As shown in Figure 3, filament size: a=12mm, b=14mm, c=5mm.The result of performance test is as follows:

Sample number	Voltage (V)	Electric current (A)	Power (W)	Luminous flux (1m)	Light efficiency (1m/W)	Life-span (h)
							1	220	4.456	980	26900	27.45	408
2	220	4.495	989	25700	25.99	376
