Description

Technology Field

[0001] The present invention relates to an LED line lighting connection device and an LED line lighting device including the same. More specifically, the invention relates to an LED line lighting connection device and an LED line lighting device including the same, which enables the connection of LED line lighting to be performed easily and efficiently by implementing a structure that allows for electrical connection of the LED circuit board of the LED line lighting along with finishing by physical coupling during assembly between components when finishing assembly and connection assembly of the LED line lighting. Background Technology

[0003] Generally, household lighting fixtures are a type of lighting installed on ceilings or walls to brightly illuminate the interior and exterior; recently, in addition to their original purpose, they are also regarded as a field of interior design aimed at enhancing decorative effects and aesthetics, and are being developed and installed in forms suitable for this purpose.

[0004] There are various types of light sources for such lighting fixtures, and recently, there has been an increasing trend in the use of lighting fixtures that utilize Light Emitting Diodes (LEDs, hereinafter referred to as LEDs) as light sources.

[0005] Such LED light sources consist of an LED module, which is the light-emitting part, and a circuit module, which is the control part. Since the LED module and the circuit module are configured separately on different substrates, there are many connecting wires linking the LED module and the circuit module, making the module arrangement complex and imposing restrictions on the design of the lighting fixture.

[0006] FIG. 1 is a drawing showing a unit LED line light according to the prior art, and FIG. 2 is a drawing showing an embodiment connecting unit LED line lights according to the prior art.

[0007] Generally, the LED line light (10) has power terminal parts (20, 30) having power terminal holes (21) with power terminals (22) provided on both sides, and are made of the same shape.

[0008] When connecting LED line lights (10) with a configuration like that of FIG. 1, the LED line lights (10, 10') are connected using a cable (50) as in FIG. 2.

[0009] However, conventional methods for connecting LED line lights featured various connection structures depending on the manufacturer (for example, methods of fixing specific male / female structural designs), which resulted in the inconvenience of having to familiarize oneself with the installation methods of various products every time for installation.

[0010] In addition, there is a possibility that the fixed male and female parts may break during the connection process, and there are problems such as a significant increase in mold manufacturing costs for each structure to accommodate various structural changes. Furthermore, existing connection methods were limited to only straight, bidirectional connections.

[0011] Therefore, there is a need for research and development regarding the end finishing of LED line lights and the connection fixing method between line lights to ensure a structure that allows for easy assembly and connection without requiring separate knowledge of each product during installation.
