In some embodiments, light-controlling device is connected with column by screw thread, and column is connected with light-passing board by screw or bolt.Thus, the dismounting of light-controlling device and easier for installation.

In some embodiments, column is one and is installed vertically on the center of light-passing board.The light at light-passing board center is generally vertical with light-passing board, and column just can parallel with the light of its position thus, and then can reduce the impact of shade on illuminating effect of column to greatest extent.

In some embodiments, light-controlling device is connected with Lamp cup by support.

In some embodiments, support is positioned at bottom or the oral area of Lamp cup.

In some embodiments, the second distribution surface is the combinatorial surface that the combinatorial surface that is made up of multiple plane or multiple curved surface form.The combinatorial surface of the second distribution surface can match with the combinatorial surface of fully reflecting surface, can reach best distribution effects thus.

In some embodiments, the second distribution surface is hemisphere face.Thus, the distribution effects of the second distribution surface is better.
