Abstract

An LED light bar with a replaceable power source. A base is inserted with an LED lamp. A lampshade covers the lamp. Both ends of the base have a connector. One connector is connected with a power supply. A connecting base is provided between the power supply and the end portion of the base. This forms the disclosed LED light bar with a replaceable power supply.

Claims

1. A light-emitting diode (LED) light bar with a replaceable power source, comprising:

a lamp using LED elements disposed on a base with a heat-dissipating structure;

a lampshade covering the lamp from the base; and

a connector on each end of the base electrically connected to the lamp base;

wherein the connector on one end of the base has a power supply and a connector base for the power supply to mount;

the power supply and the connector base have fixing elements for them to separate or assemble together; and

the power supply and the connector base have quick-connect terminals for the power supply to electrically connect to the provide electrical power to the lamp.

2. The LED light bar with a replaceable power source as in claim 1, wherein each of the connectors on both ends of the base has a first terminal and a second terminal, the first terminals are electrically connected to an AC power source, and the two second terminals are connected in parallel with a capacitor for stabilizing voltage.

3. The LED light bar with a replaceable power source as in claim 1, wherein the power supply is covered with a cover, and the quick-connect terminal of the power supply is provided on the cover and electrically connects to the quick-connect terminal on the connector base.

4. The LED light bar with a replaceable power source as in claim 3, wherein one of the quick-connect terminals of the cover and the connector base is male and the other is female correspondingly.

5. The LED light bar with a replaceable power source as in claim 1, wherein the fixing element has a blocking part on one end of the power supply, and the connector base has a positioning part that block and position the blocking part when they are connected.

6. The LED light bar with a replaceable power source as in claim 2, wherein the capacitors are AC and non-polar, and the two connecting points of the capacitor are electrically connected to the second terminals of the connectors.

7. The LED light bar with a replaceable power source as in claim 2, wherein the capacitors are DC connectors with a positive connecting point and a negative connecting point, the number of capacitors is two, and the negative connecting points of the two capacitors are connected in series and the two positive connecting points are electrically connected to the first terminals of the connectors, respectively.
