Above-mentioned strip perforation and leaded light bar are the strip of multistage turnover.

The turnover of the corresponding leaded light bar of foregoing circuit plate is made as multistage.

The inside grooves of above-mentioned leaded light bar equidistantly is provided with the leaded light raised line.

The inside grooves of above-mentioned leaded light bar equidistantly is provided with recessed of leaded light.

The inside grooves of above-mentioned leaded light bar equidistantly is provided with the leaded light tooth bar.

After adopting said structure, the strip light-emitting device of the utility model auto bulb has advantage:

1. the utility model strip light-emitting device, the strip light type that auto bulb is produced has the visible change of turnover.

2. the utlity model has the strip light-emitting device of turnover, its turning point is positioned at the outside of auto bulb, can impel auto bulb to have the function of portable lighter in daytime, Warning light or indicator.

3. the utility model strip light-emitting device is by the leaded light bar of turnover; The light of led light source is outwards derived; And with the scope that the light of strip perforation formation led light source is derived, auto bulb is produced have the strip light type of turnover, have the strip light-emitting device innovation of novelty.
