Problems solved by technology

However, the above measures do not guarantee that there will be no elemental mercury in the lamp after the fluorescent lamp is scrapped.
However, elemental mercury is easily released into the external environment, and it is not convenient to recycle.

Embodiment Construction

[0020] Embodiments of the present invention are described below with reference to the drawings.

[0021] This embodiment adopts a filamentless hot cathode fluorescent lamp (refer to the patent No. 20410017780.7 of Chen Zonglie and Chen Zhenliu) to realize the present invention. In the present invention, if the existing hot-cathode fluorescent lamp with filament is used, because the hot-cathode fluorescent lamp with filament loses the thermionic emission capability after the electron powder on the electrode is dissipated before the end of life, the current introduced into the electrode will first flow through the filament, so that The filaments at both ends of the lamp tube turn red when they are energized, which consumes most of the electric energy introduced into the electrodes at both ends of the lamp tube. As long as one end of the hot cathode fluorescent lamp without filament can work normally and the other end can receive electron emission, it can continue to work for a p...

Abstract

The invention provides a mercury recycling fluorescent lamp comprising a tube and a pair of electrodes which are respectively arranged on two ends of the tube. The mercury recycling fluorescent lamp is characterized in that the electrodes contain different electronic powder and the end of the electrode contains less electronic powder is provided with mercury eliminating agent which can be combined with mercury to generate solid matter.

Description

technical field [0001] The present invention relates to a fluorescent lamp which is easy to recover mercury. Background technique [0002] Fluorescent lamps only consume 1 / 3 of the electricity consumption of human lighting, but emit 3 / 4 of artificial light. They are the most popular energy-saving light sources in the world today. In 2007, the total global output was close to 6 billion. Based on the average mercury content of each lamp tube of 10mg, the annual production theoretical calculation of mercury consumption has reached 60 tons (the actual mercury consumption is far greater than 60 tons); at the same time, there are still 60 tons of mercury that cannot be used when the lamp tube is scrapped. Effective recycling. The dilemma is that the compact energy-saving (fluorescent) lamp CFL is currently the most suitable energy-efficient product to replace incandescent lamps. As the Global Environment Fund has successively approved the implementation of the project of "phasi...
