<p>The invention provides an improved structure of an integrated energy-saving lamp that has large power. It comprises a lamp cap, an envelope, a rectifier, and tubes which are set on the envelope. The envelope is formed of an upper lamp-house and a lower lamp-house, and an adiabatic layer is between them. The rectifier is set in the upper lamp-house and above the adiabatic layer. The lower lamp-house is formed of a tube-fix-ring, a conductive surface, and an outer lamp-house which has a U-shaped cross-section. Several radiation apertures are set in the outer lamp-house, and several holes are set in the tube-fix-ring so as to fix the tubes. Therefore, the invention has a reasonable structure, simple manufacture process, effective heat insulation, low operation temperature and long operating life.</p> |
