Abstract
The utility model relates to a lamp bulb. The utility model is characterized in that two magnesium plated wires are connected with a power supply through a screw socket, a socket or a drawing tail; the tails of the two magnesium plated wires are buckled and connected with a tungsten filament in bulb glass; the middle part of the magnesium plated wires are additionally pressed with a tungsten filament; a glass bead is arranged below the two tungsten filaments for fixing the magnesium plated wires. The utility model has the advantages of long service life and favorable visual effect.
Description
The utility model relates to a kind of bulb, particularly a kind of low power bulb.
Bulb mostly is the top that a tungsten filament places plating magnesium silk, as be low power bulb such as Christmas bulb, mostly is the top of tungsten filament clinching at plating magnesium silk, exist easily come off, the shortcoming that do not grow useful life, and behind the bright lamp, the impression weak effect.
The purpose of this utility model is exactly in order to provide a kind of long service life, the low-power bulb that impression is effective.
The utility model is to realize like this.
Adopt two plating magnesium silks by screw socket, socket or draw tail to connect power supply, the two plating magnesium silk afterbodys tungsten filament that is fastened and connected in the bulb glass; At the middle part of plating magnesium silk, tungsten filament of horizontal again or oblique clinching, there is the fixing plating of a bead magnesium silk below of two tungsten filaments.
Like this, the tungsten filament difficult drop-off that plating magnesium silk afterbody is fastened and connected, long service life; Simultaneously, light this bulb, it is simultaneously luminous to seem two light sources, and impression is effective.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a schematic diagram of the present utility model.
Among the figure, (1) is that bulb glass, (2) are that tungsten filament, (4) are bead down for last tungsten filament, (3), (5) plating magnesium silk.
Adopt two plating magnesium silks (5) by screw socket, socket or draw tail to connect power supply, in the bulb glass (1), two plating magnesium silk (5) the afterbodys tungsten filament that is fastened and connected, be the middle part of last tungsten filament (2) at plating magnesium silk, tungsten filament of clinching again, be following tungsten filament (3), there is the fixing plating of a bead (4) magnesium silk (5) below of two tungsten filaments.
Claims (1)
1, a kind of bulb is characterized in that adopting two plating magnesium silks by screw socket, socket or draw tail to connect power supply, the two plating magnesium silk afterbodys tungsten filament that is fastened and connected in the bulb glass; At the middle part of plating magnesium silk, tungsten filament of clinching again, there is the fixing plating of a bead magnesium silk below of two tungsten filaments.
