Two illuminating modules 400 are preferably provided on the main body 100 in the present embodiment. Each of the illuminating modules 400 is of a plate shape. The illuminating module 400 is included of a circuit board 410, and the LEDs 420 arranged on a side of the circuit board 410. The LEDs 420 on the illuminating module 400 are arranged toward the same direction.

[0026] Please refer to FIGs. 2 to 4. A plurality of positioning recesses 110 and a supporting surface 120 are formed on a lateral surface 101 of the main body 100, and the lateral surface 101 is preferably arranged at an included angle of 45-degree to the illuminating module 400, as shown in Fig. 1. Preferably, the positioning recesses 110 are continually arranged in juxtaposition and of a stair shape. The positioning recesses 110 and the supporting surface 120 are arranged on two opposite sides of the lateral surface 101, but it is not a limitation of the present invention. A screw hole 130 is defined on the lateral surface 101, and the screw hole 130 is preferably located between the positioning recesses 110 and the supporting surface 120. A plurality of stairs 121 corresponding to the positioning recesses 110 are arranged in juxtaposition on the supporting surface 120.

[0027] As shown in FIGs. 2 and 3, the positioning sleeve 200 is made of metal. The positioning sleeve 200 is sleeved on a pillar 500 and connected to the main body 100. Thereby, the main body 100 is fixed on the pillar 500. A beveled opening is formed at one end of the positioning sleeve 200, and a couple of positioning plates 210 are extended from the opening. The positioning plates 210 are symmetrical about an axial direction of the positioning sleeve 200. Therefore, only one positioning plate 210 will be described below. The positioning plate 210 is preferably at an included angle of 45-degree to an axial direction of the positioning sleeve 200. Each positioning plate 210 has a couple of positioning edges 211, 212 arranged opposite to each other. A protruding stage 213 is formed on each positioning plate 210 toward the other end of the positioning sleeve 200. The protruding stage 213 is located between two positioning edges 211, 212. A contacting surface 214 is concave into the protruding stage 213. The contacting surface 214 is of a curved shape, and a through hole 215 is opened on the contacting surface 214. The contacting surface 214 could be a convex curved surface formed on the protruding stage 213, but is not a limitation of the presentation.

[0028] Please refer to FIG. 3. The positioning sleeve 200 is sleeved on a vertically-arranged pillar 500, and the axial direction of the positioning sleeve 200 is arranged substantially perpendicular with the illuminating module 400. A positioning edge 211 of the positioning plate 210 is engaged into a positioning recess 110, and the other positioning edge 212 of the positioning plate 210 is engaged to a stair 121 corresponding to the positioning recess 110. In the present embodiment, the through hole 215 is of an elongated shape and extended between two positioning edges 211, 212. For example, the through hole 215 is a circular hole. The fixing bolt 300 is inserted through the through hole 215 and screwed into the screw hole 130. The main body 100 is thereby connected to the positioning plate 210 and fixed on the pillar 500. The illuminating module 400 is thereby substantially horizontal-arranged.

[0029] Please refer to FIGs. 3 and 4. The inclination of the illuminating module 400 is able to be adjusted by engaging the positioning edge 211 into various positioning recesses 110. The fixing bolt 300 is moved with the main body 100 while the main body 100 is arranged at various inclinations to the positioning sleeve 200. The fixing bolt 300 is arranged at various inclinations to the positioning plate 210 by moving the fixing bolt 300 along the through hole 215. The head 310 of the fixing bolt 300 is firmly in contact with the contacting surface 214 while the fixing bolt 300 is arranged in each inclination.

[0030] Please refer to FIG. 5. The positioning sleeve 200 is sleeved on a horizontally-arranged pillar 500. The axial direction of the positioning sleeve 200 is arranged substantially parallel with the illuminating module 400. A positioning edge 212 of the positioning plate 210 is engaged into a positioning recess 110, and the other positioning edge 211 of the positioning plate 210 is engaged to a stair 121 corresponding to the positioning recess 110. The fixing bolt 300 is inserted through the through hole 215 and screwed into the screw hole 130. The main body 100 is thereby connected to the positioning plate 210 and fixed on the pillar 500. The illuminating module 400 is thereby arranged substantially horizontal. Furthermore, the inclination of the illuminating module 400 is able to be adjusted by engaging the positioning edge 212 into various positioning recess 110.

[0031] Please refer to FIG. 6 and 7. The supporting surface 120 can be implemented without the stairs 121. While one of the positioning edges 211, 212 is engaged in one of the positioning recess 110, the other positioning edge 212, 211 is in contact with the supporting surface 120. The form of the supporting surface 120 is not limited in the present invention. For example, the surface 120 is optionally a flat shown in FIG. 6, and also optionally a curved surface shown in FIG. 7.

[0032] In the present invention, the positioning edges 211, 212 of the positioning sleeve 200 are able to be engaged into various positioning recesses 110 of the main body 100. Thereby, the relative position between the main body 100 and the positioning sleeve 200 is able to be adjusted. Therefore, compared with conventional technic, the inclination adjustment structure of the present invention can be installed more easily. The strength of the present invention is better than that of conventional technic as well.
