Abstract
Provided is a light emitting device. The light emitting device includes a control circuit and a light emitting element string. The control circuit outputs a driving power. The light emitting element string includes light emitting elements, a power line, a first receiving port, and a second receiving port. The power line is connected to the light emitting elements. A first terminal of the power line is connected to a first-stage light emitting element. The second terminal of the power line is connected to a last-stage light emitting element. The first receiving port provides the driving power to the first terminal of the power line. The second receiving port provides the driving power to the second terminal of the power line.
Claims10
A light emitting device, comprising:
- a control circuit, configured to output a driving power;
- and
- a light emitting element string, comprising:
- a plurality of light emitting elements, comprising a first-stage light emitting element located at a first terminal of the light emitting element string and a last-stage light emitting element located at a second terminal of the light emitting element string;
- a power line, connected to the light emitting elements, wherein a first terminal of the power line is connected to the first-stage light emitting element, and a second terminal of the power line is connected to the last-stage light emitting element;
- a first receiving port, connected to the control circuit, the first-stage light emitting element, and the first terminal of the power line;
- and
- a second receiving port, connected to the control circuit, the last-stage light emitting element, and the second terminal of the power line,
- wherein the first receiving port provides the driving power to the first terminal of the power line, and the second receiving port provides the driving power to the second terminal of the power line, so that voltage values at the first terminal of the power line and the second terminal of the power line are consistent.
