A frame(22) has a bent wing piece(20) with elastic force and has a combining protrusion in the inside of the wing piece. A PCB(Printed Circuit Board)(28) is located in the accommodation space of the frame, and has a number of elements(26) emitting light as a voltage is supplied. An acrylic plate(34) has a combining groove(36) inserted with the combining protrusion(24) protruded on the wing piece of the frame.
