Below in conjunction with drawings and Examples the utility model is elaborated:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is that great power LED dot matrix of the present utility model is arranged the aluminium base schematic diagram;

Fig. 3 is the utility model control module circuit block diagram;

Fig. 4 is the cutaway view of the utility model light source board internal structure.

The specific embodiment

Know by Fig. 1 and Fig. 2, the utility model comprises lamppost 1, street lamp shell 2, lampshade 3, solar panel 4, battery 6 and control module 7, also comprise be connected with this control module be arranged on outer lamp housing 2 of street lamp and the light source board 5 in the lampshade, this light source board 5 is plane structure, and the surface is provided with great power LED 12 light emitting sources that dot matrix is arranged.

In embodiment of the present utility model, be fixed with the high transparent glass lamp shade 3 of a cambered surface below the street lamp shell 2, street lamp shell 2 forms hermetically-sealed construction with lampshade 3, light source board 5 is installed in the sealing structure, and the light that great power LED 12 light emitting sources in it send passes high-transparent glass lampshade 3 and illuminates the road surface.

Be arranged with the great power LED 12 light source dot matrix that a plurality of great power LEDs 12 evenly distribute and form along aluminium base on the light source board 5 of the present utility model.In this embodiment, used 30 great power LEDs altogether, divided 6 rows, every row is respectively 3,5, and 7,7,5,3.The density of great power LED can be decided according to brightness requirement, the brightness requirement height, and great power LED density is just high, otherwise then low.
