<p>The invention discloses an energy-saving fluorescent lamp with automatically formed by a single step, and the forming method and the mould of the U-shaped tube unit. The energy-saving fluorescent lamp is formed of several single-tube units which are connected to each other with connective bridges, additionally, two walls of one tube unit are parallel to each other, and two walls also are adjacent tightly to each other. The bending direction of the two walls is the same. The advantages of the lamp are effective light utilization, short tube length, and sufficient radiation, and the lamp is automatically single forming in industry. Therefore, the lamp can work with small power, and also has low cost, high efficient, and low rejection ratio.</p> |
