Abstract
The utility model discloses a cold cathode fluorescent lamp for lighting, which comprises a lamp tube. The inner surface of the lamp tube is coated with a rear-earth three-primary-color fluorescent powder layer. Two ends in the lamp tube are respectively provided with an electrode and a horn mouth core column. The outer edge of the horn mouth of the horn mouth core column is sintered in a sealed state for integrating with the end of the lamp tube. Magnesium-coated guide wire is thermally sealed in the horn mouth core column. One end of the magnesium-coated guide wire is connected with the electrode, and the other end extends to outside of the lamp tube. Compared with the prior-art fluorescent lamp in a same standard, the cold cathode fluorescent lamp has the following advantages: high light efficiency, no light decay, energy-saving performance, long service life and higher versatility. Through setting the horn mouth core column and a glass core tube, the horn mouth of the horn mouth core column is sintered to a port of the fluorescent tube. A sealing machine which has high price and is hard to control is saved. The equipment investment is reduced for one half. The qualified finished products with stable quality can be manufactured through a common hot sealing method according to the conventional exhaust process. The operation process is greatly simplified. The worker can be qualified after training for one week. The welding is reliable and air leakage is prevented. The yield rate can reach up to 98%.
