Single lamp strip bulb with built-in resistor

Technical Field

The utility model relates to a bulb, specifically speaking relates to a built-in single lamp strip bulb of resistance.

Background

The bulb structure of current single lamp strip is built-in for the filament generally, simultaneously for guaranteeing filament current's stability, still is provided with a current-limiting resistor who concatenates with the filament outward for the lamp body, but this structure still has following defect in the application:

1. because the current-limiting resistor is arranged in the lamp holder, and the space in the lamp holder is limited, the current-limiting resistor is easy to prop against the lamp holder to cause poor contact or poor torsion of the lamp holder;

2. the process of connecting the current-limiting resistor and the outer guide wire is complicated, the mechanical operation is difficult to realize due to the close distance between the current-limiting resistor and the outer guide wire, the existing lamp cap assembly still depends on manual operation, and a large amount of human resources are occupied;

3. because the inner space of the lamp holder is small, after the lamp holder is connected with the current-limiting resistor, an insulating tube needs to be sleeved for insulation treatment, the production cost of a single bulb product is high, and the cost performance is relatively low.

In view of this, there is a need for improvements to existing bulb designs.
