In particular, as shown in FIG. 4, the first locking groove 142 may be formed in the light emitting diode substrate 132 of the light emitting diode module 130, and the first fixing protrusion 141 may have a cap member 120. It may be provided in the seating portion 122 of the. Accordingly, the first locking groove 142 formed on the light emitting diode substrate 132 while riding on the first fixing protrusion 141 while the light emitting diode substrate 132 is drawn into the seating part 122 is formed in the first fixing protrusion ( When reaching 141, the first fixing protrusion 141 may be fixed in such a manner as to be caught by the second locking groove 162.

In addition, as shown in FIG. 4, the first fixing protrusion 141 may be provided in the seating part 122, but may have an inclined surface that gradually increases in the direction in which the light emitting diode module 130 is drawn. Therefore, the light emitting diode module 130 may move while sliding smoothly riding on the first fixing protrusion 141 while being led into the seating portion.

In addition, the LED lighting apparatus 100 according to an embodiment of the present invention may further include a conductive part 150 as shown in FIGS. 2 to 4. The conductive part 150 electrically conducts the light emitting diode module 130 to the electrode pin EP when the light emitting diode module 130 is introduced into the cap member 120.

The fixing protrusion 141 may be an elastic electrode plate elastically supporting the light emitting diode substrate 132 so that the fixing protrusion 141 is held in the first locking groove 142. Therefore, the first electrode member 151, which is an elastic electrode plate, has a restoring force that pushes the light emitting diode substrate 132 toward the seating portion 122, so that an external force greater than the restoring force is not applied to the light emitting diode substrate 132. The second fixing protrusion 161 may maintain a state of being caught in the first locking groove 142. In addition, in order to withdraw the light emitting diode substrate 132 from between the seating portion 122 and the support portion 123, the light emitting diode substrate 132 may be supported by the support portion 123 with a force greater than the restoring force of the first electrode member 151.

In addition, the other end of the first electrode member 151 may have a shape bent in the direction in which the light emitting diode substrate 132 is inserted. Therefore, the light emitting diode substrate 132 may be smoothly inserted between the mounting portion 122 and the support portion 123. In particular, when the first electrode member 151 further has a shape that is convexly curved in the direction toward the seating portion 122, the first electrode member 151 may further secure contact with the second electrode member 152. Can be.

On the other hand, when the first electrode member 151 is an elastic electrode plate, the second electrode member 152 is coated on the light emitting diode substrate 132 and fixed so as to make contact with the first electrode member 151 more stable. It may be an electrode pad.

The second fixing protrusion 161 may be provided in the cap member 120, and the second locking groove 162 may be formed in the cover member 110 to catch the second fixing protrusion 161. As another example, although not shown, the second fixing protrusion may be provided in the cover member, and the second locking groove may be formed in the cap member to catch the second fixing protrusion.
