Abstract

A light-emitting diode lamp which can be directly inserted into a lamp holder supplying AC power can utilize a power supply unit in a connector to supply the rectified and transformed power to an emission board to enable the light-emitting diodes on the emission board to emit light. Since the power consumption can be greatly reduced by using the light-emitting diodes, and the power supply unit or the emission board is replaceable, respectively, the requirements of environment protection and energy-saving can be satisfied.

Claims

1. A light-emitting diode (LED) lamp used together with a lamp holder, comprising:

an emission board including a base board provided with plural light-emitting diodes;

a tube body provided for accommodation of the emission board;

two connectors being a first connector and a second connector, which are connected to two ends of the tube body, respectively, the respective connectors including two inserting electrodes to be inserted into the lamp holder; and

a power supply unit accommodated in the second connector and electrically connected to the second connector and the emission board, respectively, after transforming and rectifying an inputted AC power, the power supply unit will supply the transformed and rectified AC power to the light-emitting diodes on the emission boards.

2. The light-emitting diode lamp as claimed in claim 1, wherein the respective connectors include two axial grooves at one side thereof adjacent to the tube body, the emission board is positioned in the two grooves of the respective connectors.

3. The light-emitting diode lamp as claimed in claim 2, wherein the respective connectors include an inserting end and an assembling end, the inserting electrodes are located on the inserting ends, and the axial grooves are located in the assembling ends.

4. The light-emitting diode lamp as claimed in claim 3, wherein the second connector includes a containing portion located between the inserting end and the assembling end, and the containing portion includes a containing space for accommodation of the power supply unit.

5. The light-emitting diode lamp as claimed in claim 1, wherein an adaptor is provided between the emission board and the power supply unit, the adaptor includes a connecting portion at each of two opposite sides thereof, and the emission board and the power supply unit are connected to the connecting portions of the adaptor, respectively.

6. The light-emitting diode lamp as claimed in claim 1 further comprising two connecting portions, which are provided between the first connector and the emission board and between the power supply unit and the second connector, respectively.

7. The light-emitting diode lamp as claimed in claim 5, wherein the connecting portions are engaged to each other.

8. The light-emitting diode lamp as claimed in claim 6, wherein the connecting portions are engaged to each other.
