Problems solved by technology

[0002] At present, in fluorescent lamps (including energy-saving lamps, electrodeless lamps, germicidal lamps, etc.), mercury cannot be replaced by other substances at present, but mercury is likely to cause serious environmental pollution problems, and solid mercury (solid amalgam) is used instead of liquid Mercury can overcome the defects that liquid mercury is easy to lose, difficult to control, and difficult to recycle, so it can play a role in environmental protection
However, due to the low Hg content of fluorescent lamp tubes made of traditional solid mercury such as ZnHg or ZnSnHg, the tubes have the disadvantages of poor low-temperature start-up performance, low instantaneous brightness, and slow light-up. The mercury ball particles are relatively heavy, and the lamp tube is easy to scratch the phosphor coating during transportation; due to the limitation of the formula, the "saturation" of the existing amalgam is low, and when the mercury content exceeds 50%, it will occur Adhesion, the amalgam changes from solid state to solid solution state at room temperature, and mercury atoms will be ejected from the surface, resulting in amalgam adhesion phenomenon, which not only affects the environmental protection effect, but also brings difficulties to the lamp making process

Embodiment 1

[0010] One of the preferred solutions for high mercury content solid mercury: the mass content of each component is Hg 60%, Sn 20%, Zn 15%, Ag 3%, Ga 2%, and the solid mercury can be obtained by conventional amalgam manufacturing methods , can be applied to the manufacture of fluorescent lamps, electrodeless lamps, ultraviolet germicidal lamps and advertising neon lights. The corresponding characteristic curve is V. When the temperature is -10°C, the lamp can also take off normally, and the instantaneous luminous flux can reach more than 95% of liquid mercury; The solid mercury is used in energy-saving lamps of 9-13 watts, and only 5 mg of mercury can be used to ensure a life of 8,000 hours. The traditional mercury-containing 30% ZnHg amalgam needs 10 mg of mercury, and the initial brightness of the lamp is low. , due to the heavy weight of the mercury ball particles, it is easy to scratch the fluorescent coating inside the lamp tube during transportation.

Embodiment 2

[0012] The second optimal solution for mercury solidification with high mercury content: the mass content of each component is Hg 60%, Sn 20%, Zn 15%, Ag 3%, In 2%, which can be applied to advertising neon lights with T3 and T4 diameters. For a 1.5-2m long lamp tube, only 10mg of the solid mercury needs to be injected to achieve qualified instantaneous brightness and stable brightness. There is no mercury spot on the lamp tube, and the corresponding characteristic curve of the lamp tube is V.

Embodiment 3

[0014] The third preferred option for mercury solidification with high mercury content: the mass content of each component is Hg 60%, Sn 20%, Zn 15%, Ag 3%, Ga 1%, In 1%, which can be applied to T2 and T3 pipe diameters The cold cathode fluorescent lamp can precisely control the amount of mercury, which is safe to manufacture and use, and can eliminate mercury spots on the wall of the lamp tube. The corresponding characteristic curve of the lamp tube is V.

Abstract

The invention opened solid hydrargyrum belong to amalgam field. The weight content is: Hg 20%-65%, Sn 5%-74.5%, Zn 5%-35%, Ag 0.5%-10%, Ga 0%-10%, In 0%-10%. The solid Hg has the wide range of the Hg%, even it includes 60% Hg, it keeps the solid in the room temperature. It can be used to make the fluorescent lamp. The strip lamp has the good low-temperature characteristics and has the high brightness. Also it can use the light Hg grain, so it can decrease the damage to the fluorescent layer. The fluorescent lamp includes power saving fluorescent lamps, bactericidal lamp.
