This is to consider that the luminance standard suitable for the lighting apparatus for street lamps of different countries is different.

On the other hand, Figures 9 to 13 shows another embodiment of the lighting device for a street lamp according to the present invention, unlike the above-described line embodiment, the lamp module 200 can be spaced apart from the rotation bracket 320 intervals. As the tilting means is modified so that the same reference numerals are used for the same components, and overlapping descriptions will be omitted. In addition, the shape of the same component may be somewhat modified.

Both lower ends of the lamp module 200 are coupled to one upper end of the rotating bracket 320 by the hinge shaft 225, and both ends of the hinge shaft 225 are forcibly fitted to both ends of the rotating bracket 320. .

That is, since the hinge shaft 225 and the rotation bracket 320 are forcibly coupled, the hinge shaft 225 is supported by the friction force of the hinge shaft 225 during the rotation operation of the lamp module 200.

The hinge shaft 225 is formed to integrally protrude outward from both lower ends of the lamp module 200.

In addition, the rotation bracket 320 has a fitting hole 322 has an arc shape, and one side portion has a shape bent upward.

However, in the tilting operation, since the hinge shafts 225 formed at both lower ends of the lamp module 200 are forcibly fitted to the rotation bracket 320, the user exceeds the fitting friction force in a state in which the user grips the lamp module 200. When rotating about the hinge shaft 225 by the force, the lamp module 200 is fixed by the fitting friction force of the hinge shaft 225 after the rotation.

In addition, the movement of the lamp module 200 in the longitudinal direction with respect to the module case 100 by using the moving means is the same as the operation of the previous embodiment, a duplicate description thereof will be omitted.
