Description

Improved Assembly Installed LED Lighting Fixtures {Improved LED Lighting Apparatus}

The present invention relates to an assembly installation type LED lighting device, and more particularly, an assembly improved to minimize a dark zone in which illuminance is relatively low due to component interference in a lighting area when a plurality of LED modules are assembled It relates to an installation type LED lighting fixture.

Unless otherwise indicated herein, the material described in this section is not prior art to the claims of this application, and inclusion in this section is not an admission that it is prior art.

In general, LED lighting is known to have relatively low power consumption, high brightness, and long lifespan compared to conventional lighting lamps, and is widely used for lighting in tunnels and buildings, including home ceiling lamps, living room lamps, and kitchen lamps.

A number of LED modules can be assembled through an outlet-type connection terminal or a plug-type connection terminal for the stability and lighting efficiency of lighting required for a home or building space, and the power supplied to such LED modules is supplied through a ballast. Various R&D efforts are being made to cancel the dark zone while increasing the efficiency of LED modules and ballast power connection.

As is well known in the prior art, Korean Patent Registration No. 10-1568086 discloses an "integrally assembled ceiling lamp".

1 is a view schematically showing a conventional assembly installation type ceiling light fixture, Figure 1a is an assembly installation type ceiling light fixture of the An exploded perspective view, FIG. 1B is an excerpted perspective view of a connector.

Referring to FIG. 1, in the conventional lighting fixture, in order to cover the dark zone generated by the ballast, etc., the main body 3 and the covers 4 and 5 installed with the ballast 1 and the LED lighting unit 2 in the center are assembled up and down. It was integrally combined and made detachable for workability in the center of the cover.

However, in the above-described conventional assembly installation type lighting fixture, there is a problem that a dark zone appears relatively dark around the ballast still connected for power supply as the LED lighting module and the ballast are arranged at a predetermined interval on the substrate.

On the other hand, as a prior art for solving the dark zone problem, "connector for power supply of lighting equipment" is disclosed in Korean Utility Model No. 20-0412939. The connector presented in the prior art document proposes a configuration in which a power input side connection terminal and a power output side connection terminal are connected with a cable of a predetermined length.

However, in the conventional connector for power supply of lighting devices described above, due to the cable-terminal connection structure, when a plurality of LED modules are still assembled, the connection of cables and terminals becomes complicated and a dark zone still remains .
