Description
The utility model national uses light fixture.
Ordinary incandescent lamp bubble has plug, screw socket, bilux bulb is also arranged now, but uses for rotation, and a filament has been broken, and re-uses after the convertible direction, and the life-span doubles, but can not use simultaneously, and brightness is doubled.
The purpose of this utility model provides the bulb that a kind of convertible brightness and life-span double.
Accompanying drawing is the structural representation of bilux bulb, wherein the 1-contact point; The 2-lamp holder; The 3-switch, 4-bulb, 5-filament.
Before lamp holder (2) is arranged after bulb (4) is arranged, filament (5) is arranged in the bubble, after the have point of contact bilux bulb of (1), it is characterized in that: be the filament of two groups of parallel connections in the bubble, one group filament connects the switch (3) on the lamp holder.
This bulb can be screw socket or socket during use, and one group of filament is bright during normal switch, when this group filament damage maybe need strengthen brightness the time can be lamp holder on switch connection, another group filament is promptly bright.
The utility model novel structure, easy to use, dual-use material.
