Preferably, it is a plurality of the quantity of connecting block is four, four the circular arc of connecting block is the whole circular quarter of connecting block, and this structure is comparatively firm when being used for making the light source board place.

Preferably, four the shape of connecting block all is circular-arcly, four the cross-section of connecting block all is the U-shaped, and when this structure was used for making the light source board fixed, need not to install through the instrument, made the light source board installation dismantle comparatively convenient.

Preferably, the edge of the heat dissipation fan and the position above the mounting plate are provided with a plurality of vent holes, and the structure is used for increasing the air intake of the heat dissipation fan and improving the heat dissipation effect of the light source plate.

Preferably, the inner sides of the four connecting blocks are provided with a plurality of clamping grooves, the clamping grooves are triangular, and the structure is used for enabling the connecting blocks to fix the rectangular light source plates.

Preferably, the shape of mounting panel becomes the ring form, the surface of mounting panel is equipped with a plurality of waist type mounting holes, and is a plurality of waist type mounting hole all is circular-arc, and this structure is used for making the installation of mounting panel fixed comparatively convenient.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses an edge joint that makes the light source board is in the inboard of four connecting blocks to fix through spring tension, it is comparatively convenient to make the installation of light source board, and make the diameter size of light source board can carry out the small scale and adjust, simultaneously through setting up the draw-in groove in the connecting block inboard, the light source board that makes the shape be the rectangle also can be fixed, make radiating seat accommodation wider, secondly, through setting up the heat dissipation fan in the below of light source board, the heat that makes light source board lamp source can directly be discharged, make the radiating effect of light source board improve.
