Abstract: Disclosed is a lamp tube structure with reflective surface. In this invention, the lamp tube structure with reflective surface can be achieved by forming a reflective layer on the inner surface or outer surface through coating, plating, chemical vapor deposition, sputtering, evaporation deposition or pasting. The lamp tube structure with reflective surface can also be achieved by the assembling the parts with reflective surface in combination with the transparent lamp tube or lamp tube parts, in this invention. The incorporation of the reflective surface lets the lamp light be utilized more effectively, and it is helpful to energy saving.
