PURPOSE: A substrate embedded signal lamp is provided to reduce the whole volume of the lamp by installing an LED control circuit and a PCB substrate on the inner side of an LED substrate. CONSTITUTION: A fixing substrate(100) is formed on the lower part. An LED substrate(200) includes LEDs on the surface. The LED substrate is installed on the upper part of the fixing substrate in the shape of a polygonal cylinder. A PCB substrate(300) is installed in the LED substrate. |
