Problems solved by technology

In this scheme, mercury Hg3-12%, the content is too high, the role of the decomposition of indium compound and the coexistence of solid and liquid two phases to stabilize the vapor pressure is not enough to maintain the stability of the vapor pressure, and the working temperature range ΔT95 is small, which does not meet the condition 1

Abstract

The invention relates to a solid amalgam material, in particular to an optimized indium-sn-bismuth-amalgam which is used for a low pressure mercury discharge lamp and simultaneously satisfies the following characteristics: 1. the melting temperature is higher than or close to the maximum working temperature of delta T95; 2. for lamp tubes with the diameters phi less than 10mm, the working temperature region is 90-133 DEG C, and the delta T95 is more than 30 DEG C; 3. lead is not contained; and 4. the mass content of mercury is maximized under the premise of ensuring the performance, and the indium-sn-bismuth-amalgam has low use cost and is easy to place. The indium-sn-bismuth-amalgam contains the following components according to mass content: 38-46% of bismuth, 47-55% of sn, 5.3-9% of indium and 1.3-2.6% of mercury, wherein the mass ratio of the bismuth (Bi) to Sn is less than one. Lamps using the amalgam have high luminous efficiency, good consistency and relatively low cost; and the probability of photoelectric parameter degradation as the amalgam is melted and flows into the lamps is small.

Description

technical field [0001] The invention relates to a solid amalgam material, in particular to a bismuth-tin-indium amalgam for a low-pressure mercury discharge lamp. Background technique [0002] At present, three types of controllable mercury vapor pressure amalgam are mainly used in the compact fluorescent lamp with cover or the compact fluorescent lamp with tube wall load. In addition to containing a small amount of mercury, Bi-Pb-Sn-Hg also contains a large proportion of lead Pb, which does not meet the requirements of environmental protection and will be restricted for use. The first peak mercury vapor pressure of Bi-In-Hg is relatively low, and there is an inflection point where the mercury vapor pressure drops significantly in the middle of the working temperature range. For small-diameter compact fluorescent lamps with a diameter of φ<10mm, ΔT95 is far less than 30°C, generally 10- 15°C, the working temperature range is narrow, and ΔT95 refers to the continuous work...
