Abstract

The light source module provided by the present invention includes a base plate (1) and a plurality of LED lights (101, 102, 103) arranged on the base plate. These LED lights are distributed on the base plate in such manner that all of the light centers of the LED lights define together a triangle shape. An angle of 50-70 degrees is defined between a LED light and two adjacent LED lights. The present invention has many advantages. For example, because the LED lights are distributed in a triangle arrangement, the dark regions are reduced effectively. Moreover, alternate dark and bright strips are eliminated. In addition, base plates can be assembled quickly by means of connective members (105,107).
