Abstract

An LED lamp with replaceable power supply includes a tubular body, a light module, a power supply, and two power connectors. The light module is disposed within the tubular body. The light module includes a circuit board and a plurality of LEDs. The LEDs are electrically coupled to the circuit board and are disposed on the bottom side of the circuit board. The power supply is replaceably disposed on the light module and is electrically coupled to the circuit board. The two power connectors are respectively coupled to the two ends of the tubular body and are electrically coupled to the power supply.

Claims

1. An LED lamp with replaceable power supply, comprising:

a tubular body;

a light module, disposed within the tubular body, the light module including a circuit board and a plurality of LEDs, the plurality of LEDs being electrically coupled to the circuit board and disposed on the bottom side of the circuit board;

a power supply, replaceably disposed on the light module and electrically coupled to the circuit board; and

two power connectors, respectively coupled to the two ends of the tubular body and electrically coupled to the power supply.

2. The LED lamp with replaceable power supply according to claim 1, wherein the tubular body comprises a plurality of venting holes thereon.

3. The LED lamp with replaceable power supply according to claim 1, wherein the two ends of the tubular body are each defined a connecting section adapted to couple the two power connectors to the tubular body respectively.

4. The LED lamp with replaceable power supply according to claim 3, wherein each of the connecting sections of the tubular body includes two open grooves and a lock hook defined between the two open grooves, each of the two power connectors including an annular body and lock slots defined on the annular body, the locks slots being adapted to engage with the lock hook in a locking configuration.

5. The LED lamp with replaceable power supply according to claim 1, wherein the light module is replaceably disposed within the tubular body.

6. The LED lamp with replaceable power supply according to claim 1, wherein the LEDs are disposed in a spatial arrangement.

7. The LED lamp with replaceable power supply according to claim 1, wherein the light module further comprises a first power socket electrically coupled to the electric circuit, the power supply having a power supply plug adapted to insert in the first power socket.

8. The LED lamp with replaceable power supply according to claim 1 further comprising two power sink plugs electrically coupled to the two power connectors respectively, the power supply comprising two second power sockets adapted to receive the two power sink plugs respectively.

9. The LED lamp with replaceable power supply according to claim 1, wherein the two power connectors are removably coupled to the two ends of the tubular body.

10. The LED lamp with replaceable power supply according to claim 1 further comprising a nut having a lock groove and an internal thread abutting the lock groove defined therein, each of the two ends of the tubular body having an external thread adapted to mate with the internal thread of the nut, each of the power connectors having a lock ring on an outer edge thereof adapted to fit within the lock groove.
