Description

Adjustable lamp

The utility model relates to a kind of electric lighting device, especially the incandescent lamp that is made of lamp holder, glass shell, wick, light-emitting filament and support thereof.

The present ordinary incandescent lamp that uses, it has only a light-emitting filament, luminous power is fixed, for example: 15 watts, 30 watts, 100 watts etc.,, add some complicated circuit on the same lamp if when different brightness requirement is arranged, and, in a single day filament has blown, and then whole lamp has just been scrapped, and has caused inconvenient, waste.

The purpose of this utility model provides a kind of incandescent lamp, can access several different luminous powers on the same lamp, and the life-span is the integer multiple of ordinary incandescent lamp.

For achieving the above object, the technical solution of the utility model is: in the glass shell that the plain edition incandescent lamp vacuumizes, locate in that former filament is other, upper and lower etc., increase several filaments.One end of these several filaments is communicated with lead-in wire, and causes on the lamp holder, and as an electrode, the other end is arranged on the garden contour, as deciding contact respectively with causing on the head.Be in garden screw in the heart and be connected for the Luo line with lamp holder, the control moving contact, and as an electrode, with moving contact for being electrically connected, when moving contact adjusting and which were decided contact and contact, it is just shinny when conducting electricity that decides the filament that contact connects.The slotting formula bulb socket of this lamp and ordinary incandescent lamp is used.

The lamp of above structure can have several different luminous powers, and is simple in structure, the life-span of having improved lamp widely, cut the waste, and enlarged usage range.

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Shown in Figure 1, be the stereogram of the utility model embodiment.

Shown in Figure 2, be the lamp holder stereogram of the utility model embodiment.

With Fig. 1 as can be known: lamp sleeve 2 is the same with ordinary incandescent lamp, plays a part to be connected and fixed glass shell 5 and lamp holder 1, is generally made by iron plate.Vacuumize by vacuumizing mouth 9 between glass shell 5 and the wick 6, make to be installed in the filament 7 that supports on 8 one ends and to be among the vacuum, support 8 the other end and then cast on the wick 6 that glass is made.Support 8 and generally serve as by copper cash, mutually insulated between support, support 8 is divided into two-layer in Fig. 1.Filament 7 can have many, and their end all is connected with lead-in wire 10, and draws the contact of receiving on the lamp holder 1 11, becomes an electrode; And their other end 4 is connected with each lead-in wire respectively, and draws respectively and connect deciding on contact 12,13,14 and 15 on the row lamp holder 1; Any one distance between each filament is not less than 1.5 centimetres.Filament material is identical with ordinary incandescent lamp.

As shown in Figure 2, for the complete stereogram of lamp holder 1, decide the last plane that contact 12,13,14 and 15 is lower than lamp holder 1, being in screw contact 17 is on the garden contour of the garden heart.Screw contact 17 is one of two electrodes, is connected for the Luo line with lamp holder 1, and it can loosen moving contact 16 or compress, and regulating and to decide contacting of contact, and is electrically connected with moving contact 16.If which moving contact 16 decided contact and contacted with, the filament that is connected with this contact when energising is just luminous.The contact head of moving contact 16, the semicircle type that be to protrude so that with decide contact and contact and conduct electricity well.The material of lamp holder 1 is the insulation heat resistant plastice, and deciding contact material is copper or aluminium, and the material of moving contact 16 and screw contact 17 is a copper.

When using this dimmable lamp, screw contact 17 is unscrewed, regulate moving contact 16, decide contact and contact with required one, screw 17 is tightened, make, decide contact and contact, inject then in the common socket bulb socket, two bayonet locks 3 block the bayonet socket of socket bulb socket, make it firmly to be connected with bulb socket, in bulb socket, contact 11 and screw contact 17 contact with two electrodes in the conventional jack bulb socket respectively, if energising, that root filament light-emitting that then is connected with moving contact.

In Fig. 1 that the utility model is implemented, four filaments are arranged, its power is 15 watts, 40 watts, 100 watts and 200 watts by its arrangement of drawing contact 12,13,14,15, can regulate moving contact 16 as required, thereby obtain required luminous power.In actual applications, the power of each filament can be provided with as required.

This dimmable lamp manufacture craft is the same substantially, simple in structure with ordinary incandescent lamp, but the life-span be medium-sized more than several times, and, different luminosity can be arranged, be a kind of novel lamp that extensive use is arranged.

Claims (5)

1, a kind of incandescent lamp of forming by lamp holder, glass shell, wick, filament and support thereof, it is characterized by: alight silk (7) can be several, their end is linked together by lead-in wire (10), and draws the contact (11) that is connected on the lamp holder (1), as an electrode; The other end is connected with each lead-in wire (4) respectively, draws respectively to be connected to and decides contact (12), (13), (14) and (15) on the lamp holder (1), and when moving contact (16) and which were decided contact and contact, if energising, the filament that root is attached thereto was just luminous; Screw contact (17) as one of electrode is electrically connected with moving contact (16), by screw contact (17), can regulate moving contact (16).

2, adjustable lamp according to claim 1 is characterized by: filament (7) can be two-layer or the multilayer setting, and still, any distance between the filament (7) all is not less than 1.5 centimetres.
