The plurality of LED elements 10 may be arranged in various forms according to the structure of the LED lighting apparatus according to the present invention.

For example, when the LED lighting apparatus according to the present invention has a long structure such as a fluorescent lamp as shown, the plurality of LED elements 10 may be arranged as follows.

That is, the plurality of LED elements 10 may be arranged along at least the longitudinal direction (arrow L) of the tubular member 30. At this time, the plurality of LED elements 10 may be arranged in a straight line along the longitudinal direction (arrow L) as shown, as well as may be arranged in various forms such as zigzag, wave (wave).

In addition, the plurality of LED elements 10 may be arranged along the longitudinal direction (arrow L) and arranged in one row as shown, or in a plurality of rows, although not shown.

The LED substrate 20 has a plurality of LED elements 10 are arranged along the longitudinal direction (arrow L) as described above, the light of the LED element 10 is the width direction (arrow) of the tubular member 30 In order to be transmitted toward W), it is possible to take the form of a panel which is formed to have a long length relative to the width and is installed along the longitudinal direction (arrow L). Here, the LED substrate 20 is formed to have a suitable thickness according to the weight of the installation installed on the LED substrate 20, including the LED element 10, the size of the LED substrate 20, and the like, the general fluorescent lamp As an alternative use, the tubular member 30 may have a thickness considerably thinner than the width of the tubular member 30.

At this time, the LED substrate 20 may be installed on both sides of the LED element 10, but in the case of installing the LED lighting fixture according to the present invention, such as a fluorescent lamp on the wall surface only on one side as shown The LED element 10 may be installed. Hereinafter, for convenience of description, the surface on which the LED element 10 is installed on both sides of the LED substrate 20 is called the front face 21, and the opposite surface is referred to as the rear face 22.

The panel-shaped LED substrate 20 may be formed in various shapes and structures, such as a quadrangle, a polygon, a circle, an ellipse, and an irregular shape, as shown.

In addition, the panel-shaped LED substrate 20 may be formed in a planar structure consisting of a single surface as shown in Figures 1 to 7, and formed in a three-dimensional structure consisting of a plurality of surfaces as shown in FIG. Can be. Here, although the LED substrate 20 is formed of a plurality of surfaces, as shown in FIG. 8, a plurality of LED elements 10 may be installed on only one surface, or a plurality of LED elements may be provided on two or more surfaces, respectively. 10 may be installed.

The LED substrate 20 may be formed of a general panel or an electric circuit for lighting, and when the electric circuit is formed, the LED substrate 20 may be made of FPCB, a metal PCB having excellent heat dissipation, and the like. Can be.

The tubular member 30 may be formed of various materials. However, since the LED substrate 20 is inserted into the internal space 30A of the tubular member 30, light of the LED element 10 may be transmitted. It is preferably formed of a material that can be.

That is, the tubular member 30 may be more preferably formed of a synthetic resin such as plastic. At this time, the LED element 10 is bright and the straightness of the light is strong, the tubular member 30 may be more advantageous in terms of anti-glare and the like is formed of a translucent material rather than a transparent material.

In particular, the tubular member 30 supports the support part 32 so as to support the LED substrate 20 inserted into the inner space 30A opened along the longitudinal direction (arrow L) of the tubular member 30. Can have

The support part 32 is installed along the longitudinal direction (arrow L) so that the LED substrate 20 is installed along the longitudinal direction (arrow L), as described above, so as to sufficiently support the LED substrate 20. It may be desirable to form long.

On the other hand, the tubular member 30 is a light transmission direction (arrow P) side front portion 34 of the LED element 10 in order to diffuse the light generated from the LED element 10 in the circumferential direction (arrow) Along the C) it may be formed as a convex curved surface toward the opposite side of the LED substrate 20. In this case, the rear portion 36 of the tubular member 30 may take a curved surface as shown in FIGS. 1 to 3 and 6, or may have a flat surface as shown in FIG. 5, but is not limited thereto. It can be formed in various shapes.

The tubular member 30 may have a plurality of projections 36A formed on the outer surface of the LED element 10 opposite to the light transmission direction (arrow P), that is, on the outer surface of the rear portion 36. The cross-sectional area of the protrusion 36A may be increased to improve heat dissipation, and the tubular member 30 may be reinforced.

The tubular member 30 protrudes into the inner space 30A of the tubular member 30 toward the rear surface 22 of the LED substrate 20 to support the LED substrate 20. ) May be further included. That is, the support protrusion 38 is positioned between the rear portion 36 of the tubular member 30 and the rear surface 22 of the LED substrate 20 to support the LED substrate 20 to support the LED substrate ( 20) warpage deformation and the like can be prevented. In addition, the tubular member 30 may be reinforced by the support protrusion 38.
