Embodiment 1

[0007] One of the preferred schemes of the present invention: a low-temperature amalgam, the weight percentage of each component is Ag3.5%, Cu1.5%, Sn45%, Hg50%, and energy-saving lamps can be made from this amalgam. The working temperature is 40°C-50°C, and the characteristic curve provided by this amalgam is very close to pure mercury; at normal temperature, the mercury pressure provided by it is about 94% of pure mercury, and it has good low-temperature start-up characteristics. The operating temperature of the amalgam increases with decreasing mercury content.

Embodiment 2

[0009] Two of the preferred scheme of the present invention: a kind of low-temperature amalgam, the weight percent composition of each component is Ag0.5%, Cu2.0%, Sn77.5%, Hg30%, the mercury content of this amalgam is relatively Less, suitable for bare spot energy-saving lamps with high working temperature, and can be applied to ring lights, 2D lights, 2U lights, spiral lights, etc.

Embodiment 3

[0011] The third preferred solution of the present invention: a low-temperature amalgam, the weight percentage of each component is Ag5.0%, Cu2.0%, Sn48%, Hg45%. The amalgam with more mercury content is suitable for It is suitable for straight tube fluorescent lamps with low working temperature, such as T8, T5, T4 lamps, etc.

Abstract

This invention discloses a low temperature amalgam with the weight percentage of the following components: Ag 0.5%-53%, Gu%-2.0%, Sn 40%-79.5% and Hg 20%-53%, which is solid at normal temperature and lamps made of it have good low temperature start property, and can used in fluorescent lamp and energy-saving lamps instead of pure Hg.

Description

technical field [0001] The invention relates to an amalgam material used for fluorescent lamps and energy-saving lamps. Background technique [0002] In the production fields of fluorescent lamps and energy-saving lamps, energy-saving lamps with high working temperature (stable tube wall temperature) (60°C-120°C) all use medium-temperature and high-temperature amalgam; but the working temperature is low (40°C-50°C) Pure mercury is still used in straight tube fluorescent lamps (T8, T5, T4 lamps, etc.) and energy-saving lamps with bare spots. Its shortcoming is: pure mercury is easy to lose, and causes environmental pollution, meanwhile, the amount of mercury used by each lamp tube is difficult to control. Contents of the invention [0003] The object of the present invention is to provide a kind of low-temperature amalgam that can overcome the above-mentioned defects, which can provide a mercury pressure close to pure mercury at room temperature and low temperature, and th...
