The bracket 160 includes a “U” shaped holder 162 having an opening 161 on one side thereof. The holder 162 includes both side walls 162a and a center wall 162b, and a locking protrusion 163 is formed on both inner side walls 162a of the holder 162. The locking protrusion 163 has a shape corresponding to the first locking groove 102 to be coupled to the first locking groove 102 of the tube 100. In addition, the fastening grooves 164 are formed in the center wall 162b of the bracket 160 so that they can be coupled by screws (not shown). The center wall 162b is formed flat, and when the tube is coupled to the bracket 160, the center wall 162b corresponds to the flat surface 100bp of the tube 100.

As such, the tube 100 of the lighting apparatus according to the present invention is designed to be applicable to various types of brackets.

As described above, the light emitting device built-in lighting device according to the present invention can be easily adjusted by changing the direction in the state coupled to the bracket, the airtightness is maintained even when used outdoors to solve the waterproof problem. Therefore, it is possible to greatly reduce the occurrence of electrical problems due to leakage when used outdoors. In addition, the sheet for covering the rear surface of the substrate on which the light emitting device is mounted can be easily inserted into the inside of the lighting apparatus, thereby preventing the sheet from being damaged. In addition, since the external appearance and the electrical coupling structure have not been greatly changed, there is a great advantage in productivity.
