PURPOSE: A method for manufacturing a sub lighting device for a streetlight and the sub lighting device made by the same are provided to maximize the light diffusion effect of an LED by adopting a light diffusion plate made of polycarbonate on the outer side of an acryl light guide panel. CONSTITUTION: A plurality of light diffusion grooves(1') are formed on the upper and lower surfaces of an acryl plate by a V cutting process. A plurality of LED insertion grooves(11) are formed on one side of the acryl light guide panel. An LED(12) of various colors is installed in the LED insertion groove. A light diffusion plate(3) is attached to the outer side of the upper and lower sides of the acryl light guide panel by using a double sided tape(2). A screen print unit(4') is formed on the inner side of a display panel(4) facing the light diffusion plate. |
