Double-helix energy saving lamp

Abstract

The invention discloses a double-helical energy saving lamp, which is characterized by comprising a first single-helical lamp and a second single-helical lamp which have the same structure and are in a cylindrical shape, wherein the first single-helical lamp screws in the second single-helical lamp in the same direction to form a cylindrical complex by nesting with the second single-helical lamp;and a fixing mechanism for supporting and fixing the first single-helical lamp and the second single-helical lamp is arranged on the complex. The double-helical energy saving lamp has the advantages that the two single-helical lamps operate independently, for a driving circuit, the effect is equivalent to the conventional double-helical lamp with halved length, and thus the double-helical lamp ismatched with the driving circuit easily, so that the reliability of driving matching between a ballast and the lamp is improved; and simultaneously, the double-helical energy saving lamp consists of the two single-helical lamps, and the two single-helical lamps are made without needing long glass pipes, and thus the double-helical lamp has a simple manufacturing process and can better meet the requirements of the large-scale production of high-power helical lamps.

Description

technical field [0001] The invention relates to a lamp tube, in particular to a double-helix energy-saving lamp tube. Background technique [0002] With the improvement of lighting quality, the most scientific way to save lighting costs is to effectively use energy-saving lamps. Energy-saving lamps have many advantages such as energy saving, high luminous efficiency, long life, environmental protection, good color rendering, and compact structure. They are more and more widely used and more and more types. Spiral energy-saving lamps are a common type of energy-saving lamps. The lamp tubes used in spiral energy-saving lamps are usually double-helix energy-saving lamp tubes. To achieve high power for this type of energy-saving lamps, the length of the lamp tube is generally extended to meet the requirements. However, The longer the length of the lamp tube, the higher the tube voltage will be. If the tube voltage is too high, it will be difficult to ensure the reliability of t...

Spiral energy-saving lamps are a common type of energy-saving lamps. The lamp tubes used in spiral energy-saving lamps are usually double-helix energy-saving lamp tubes. To achieve high power for this type of energy-saving lamps, the length of the lamp tube is generally extended to meet the requirements. However, The longer the length of the lamp tube, the higher the tube voltage will be. If the tube voltage is too high, it will be difficult to ensure the reliability of the drive matching between the ballast and the lamp tube; The very long glass tube and the large-scale heating and bending process increase the difficulty of production, and it is difficult to meet the requirements of large-scale production; Methods such as using a manufacturing process that makes the top of the lamp tube slightly protrude a small part as the cold end, it has been difficult to fully achieve the purpose of controlling the temperature of the cold end, thus affecting the light efficiency of the high-power lamp tube
