Abstract

A fluorescent light fixture that includes a lamp assembly having a circuit board therein where various components for the lamp'"'"'s operation are provided; lamp fixing members for connecting the lamp by inserting them into both ends of the lamp assembly; an upper cover covering the top surface of the lamp assembly; a connector connected to the lamp fixing member through an installation groove at one end of the lamp assembly; and a coupler coupling a multiple connectors. Therefore, the lamp has an improved structure of the lamp assembly in order to allow the lamp itself to be replaced, and improved connections between the lamp assemblies.

Claims

1. A fluorescent light fixture including:

a lamp assembly;

a lamp fixing member for connecting the lamp by inserting it into both ends of the lamp assembly, including a key slot, and a key for opening/closing the key slot so that the lamp can be removed from the lamp assembly through the key slot;

an upper cover covering the top surface of the lamp assembly;

a connector connected to said lamp fixing member through an installation groove at one end of the lamp assembly; and

a coupler coupling said connector to other similar connectors.

2. The light fixture as defined in claim 1, wherein a transparent or translucent fluorescent lamp cover is additionally installed at the lamp assembly into which the lamp is inserted.

3. The light fixture as defined in claim 1, wherein a pair of channel shaped brackets are elastically hooked onto the upper cover in order to attach the lamp assembly to a flat surface.

4. The lamp as defined in claim 3, wherein multiple long grooves in the upper cover, mate with protrusions on the mounting brackets so that the lamp assembly does not slide out of said mounting bracket.

5. The light fixture as defined in claim 1, wherein electric power is supplied through a connecting cable inserted into one side of the coupler, and a plug connected therewith.

6. The light fixture as defined in claim 5, wherein two lamp assemblies are connected at a fixed interval with a connecting cable, where instead of a plug at one end, a connector connects to the second lamp assembly.

7. The light fixture as defined in claim 1, wherein multiple elastic hooks protruded from the upper portion of the lamp assembly and are inserted into insertion grooves of the upper cover to fasten the upper cover.
