The cap member protrudes from the inner surface of the cap body, facing the direction in which the LED substrate is drawn, so that when the LED substrate is drawn into the hollow portion, the LED substrate is placed between the cap member and the seating portion And a support for supporting the electrode pin.
The first latching groove may be formed on the LED substrate, and the first latching protrusion may be provided on the latching portion.
The first fixing protrusion may have an inclined surface that is provided on the seating portion and gradually increases in a direction in which the LED module is inserted.

Wherein the conductive portion comprises: a first electrode member which is provided on the support portion and has one end electrically connected to the electrode pin and the other end positioned on a surface of the support portion facing the seating portion; And a second electrode member provided on the light emitting diode substrate and contacting the first electrode member when the LED substrate is inserted between the seating portion and the support portion.
Wherein the first electrode member presses the LED substrate toward the seating portion when the LED substrate is inserted between the seating portion and the supporting portion so that the first fixing protrusion is retained in the first retaining groove And may be an elastic electrode plate for elastically supporting the light emitting diode substrate.
The other end of the first electrode member may have a bent shape in a direction in which the LED substrate is inserted.
The second electrode member may be an electrode pad coated on the light emitting diode substrate.
The LED lighting apparatus according to an embodiment of the present invention may further include a second fixing unit fixing the cover member to the cap member when the cover member is drawn into the cap member.
The second fixing portion may include: a second fixing protrusion provided on one of the cover member and the cap member; And a second latching groove formed in the other one of the cover member and the cap member so that the second latching protrusion is caught.
The second fixing protrusion may be provided on the inner circumferential surface of the cap member, and the second locking groove may be formed on the cover member.
The second fixing protrusion may have an inclined surface that gradually rises toward the inner side of the cap member toward the direction in which the cover member is drawn toward the cap member and tilts.
As described above, the LED lighting apparatus according to the embodiment of the present invention can have the following effects.
According to the embodiment of the present invention, since the technical constitution including the cover member, the cap member, the light emitting diode module and the first fixing portion is provided, the light emitting diode module is pulled out from the cap member through the first fixing portion Can be prevented. Further, the first fixing portion may include a first fixing protrusion and a first latching groove, the first latching groove may be formed on the LED substrate, and the first fixing protrusion may be provided on the capping member. Since the first latching groove is formed on the easy light emitting diode substrate, the manufacturing can be facilitated. In particular, the technical structure in which the light emitting diode substrate and the cap member are fixed through the first fixing unit can be easily processed as compared with the technical construction in which the cover member and the cap member are fixed. That is, when the cover member is made of glass, there may be a problem that the cover member is easily cracked when the cover member is processed into the latching groove. However, if the latching groove is formed on the LED substrate, such a problem can be solved.
In addition, according to the embodiment of the present invention, it is possible to easily separate and assemble the light emitting diode module and the cap member without providing a separate electric wire, since the present invention further includes a conductive part.
Further, according to the embodiment of the present invention, since the technical constitution further includes the second fixing portion, the cap member can be prevented from being detached from the cover member through the second fixing portion.
