Description

[0001] DESCRIPTION [0002] LIGHT MODULE AND LIGHT APPARATUS [

An embodiment relates to a lighting module and a lighting device.

In an illumination device such as an electric signboard used for indoor or outdoor advertisement or the like, a plurality of light sources may be disposed on a substrate so that a logo or the like displayed from such light sources can be visually recognized from the outside.

Such a lighting apparatus can be applied to different sizes and different groups depending on the application field and purpose.

For example, depending on the field utilized, the number of light sources disposed in the substrate may be different from each other.

The light sources may include a plurality of wiring electrodes for controlling power supply and driving of the light source. The wiring electrodes are disposed between the light sources on the substrate and are drawn out to be connected to an external driving circuit to control the operation of the light source.

On the other hand, when the distance between the light sources disposed on the substrate is increased, the overall resolution of the illumination module is lowered.

Accordingly, the more intensively the light sources are disposed on the substrate, the higher the resolution of the lighting module can be

At this time, as the light sources are arranged intensively, that is, as the spacing between the light sources is made smaller, the area where the wiring electrodes disposed between the light sources are disposed can also be reduced.

Thus, there is a problem that the step of disposing the wiring electrodes may be difficult. Further, as the width of the wiring electrode is reduced, there is a problem that the overall resistance of the wiring electrode is increased.

That is, as the spacing between the light sources is reduced, problems may arise in the design and characteristics of the wiring electrodes.

Accordingly, there is a need for a lighting module and a lighting device of a new structure capable of solving the above problems.

Embodiments provide an illumination module capable of reducing the space between light source modules and including low-resistance wiring electrodes and a lighting apparatus including the same.

An illumination module according to an embodiment includes: a first substrate; A second substrate disposed on the first substrate; A plurality of first light source modules disposed on the first substrate; A plurality of second light source modules disposed on an area between the first light source modules on the second substrate; A first wiring electrode disposed on the first substrate and electrically connected to the first light source module; And a second wiring electrode disposed on the second substrate and electrically connected to the second light source module, wherein the first light source module and the second light source module include a plurality of light emitting diodes and a common electrode, , The first wiring electrode and the second wiring electrode are electrically connected to the light emitting diode and the common electrode, and the second substrate has a first hole in the region between the second light source modules that exposes the first light source And the position of the second light source module and the position of the first hole correspond to each other.

The illumination module according to the embodiment and the illumination device including the same can reduce the interval between the light source modules. Accordingly, it is possible to prevent the size of the lighting module from increasing as the number of the light source modules increases.

Also, the resistance of the wiring electrode connected to the light source module can be reduced. In detail, by disposing the light source modules in the upper and lower directions so as not to overlap each other, it is possible to secure a sufficient arrangement area of the wiring electrodes connected to the light source module.

As a result, even if the distance between the light source modules is reduced, the size of the arrangement region of the wiring electrodes is not reduced. Therefore, the wiring electrodes can be arranged with a sufficient width, The arrangement process can be facilitated, and the resistance can be prevented from increasing as the width of the wiring electrode is reduced.

Accordingly, the illumination module and the illumination device including the same according to the embodiment can intensively arrange the light source module, thereby improving the overall resolution of the illumination module, and can arrange the low resistance wiring, Can be implemented.

In addition, the adhesive layer 200 may be formed with a second hole H2. A plurality of second holes H2 may be formed on the second substrate 110 so as to overlap with the first light source module 310,

The positions of the first hole (H1) and the second hole (H2) may overlap each other. The positions of the first hole (H1) and the second hole (H2) may be the same. The number of the first holes H1 and the number of the second holes H2 may be equal to each other.

The size of the first hole (H1) and the second hole (H2) may be larger than the size of the first light source module (310). In detail, the width of at least one of the first hole (H1) and the second hole (H2) may be greater than the width of the first light source module (310).

For example, the width of at least one of the first hole (H1) and the second hole (H2) may be about 1.1 times the width of the first light source module (310). In detail, the width of at least one of the first hole H1 and the second hole H2 may be about 1.1 to 1.5 times the width of the first light source module 310.

For example, the first hole H1 and the second hole H2 may have a size of about 1 mm larger than the width and the vertical width of the first light source module 310 and the second light source module 320, It can be big.

Accordingly, it is possible to secure a sufficient space for disposing the first light source module in the first hole (H1) and the second hole (H2), thereby reducing the process error.

For example, the size of the second hole H2 may be larger than the size of the first hole H1. Accordingly, it is possible to mitigate process difficulties due to tolerances in the process of bonding the first substrate 110 and the second substrate 120.

The size of the first hole H1 may be larger than the size of the second hole H2 so that the adhesive layer 200 can more firmly support the first light source module 320 And the reliability of the lighting module can be improved.

The first light source module 110 disposed on the first substrate 110 on one side of the second substrate 110 is exposed by the first hole H1 and the second hole H2 3, the first light source module 310 may protrude from the upper surface of the second substrate 120 (the surface opposite to the first surface contacting the first substrate 110) . That is, the first light source module 310 may be disposed higher than the upper surface of the second substrate 120.

The thicknesses of the first light source module 310, the first substrate 110 and the adhesive layer 200 are determined by the thickness of the first light source module 310, the first substrate 110, Can be defined as the distance from the bottom surface to the top surface.

Accordingly, the second light source module 320 can emit light toward the upper side of the second substrate 120.

Although holes are formed in both the first substrate 110 and the adhesive layer 200 in FIGS. 1 and 3, the present invention is not limited to this, and the first substrate 110 and the adhesive layer 200 A hole may not be formed in the first substrate 110 or a hole may be formed in the first substrate 110 or the adhesive layer 200.

Holes are not formed in the first substrate 110 and the adhesive layer 200 by controlling the light transmittance of the first substrate 110 and the adhesive layer 200, Even if a hole is formed in only one of the adhesive layers 200, the light can be emitted in an upward direction of the second substrate 120. Accordingly, it is possible to omit a separate hole forming step in the first substrate 110 and the adhesive layer 200, so that the process efficiency can be improved, and strength reduction and adhesion decrease due to hole formation can be reduced .
