| Abstract: | LED signals can be divided into spot lighting type and matrix type based on the light source type.Matrix type LED signing has some shortages because of its own characteristics,i.e.,interface matching,filament inspection and filament safety ect.To solve those existing problems,the spot type signaling is developed.In this paper,the working principle of the spot type signaling is introduced and its advantage is listed.At last the market prospect of such products is analyzed. |
