Problems solved by technology

[0002] Fluorescent lamps rely on the ultraviolet rays radiated by mercury atoms to excite phosphors to emit light. Mercury is an indispensable material in the production of fluorescent lamps. Because mercury is volatile and easy to lose, it is easy to cause environmental pollution in the process of making lamps. In addition, The amount of mercury used in making lamps is not easy to control; in order to reduce environmental pollution in the process of making lamps, amalgam materials are used to replace pure mercury in the prior art. Amalgam is made of binary or more alloy materials containing mercury. It is in solid state. With the development of technology, some trace elements are added to the amalgam material to improve its characteristics; but no matter how it is improved, the volatility of mercury will gradually increase with the increase of the mass content of mercury in the amalgam material. How to reduce the volatilization of mercury and protect the lighting environment has become a major problem in the lighting industry

Embodiment 1

[0014] As shown in Figure 1, it is a mercury release device for fluorescent lamps, which is composed of a coating 1, an amalgam layer 2, and a core 3. The coating 1 is densely covered on the outer surface of the amalgam layer 2, and the core 3 is set on the amalgam. Inside the layer 2; the core 3 is made of a material that is inert to mercury, such as at least one or several of Fe, Co, Ni, Cu, or one of glass, ceramics, and high-temperature-resistant polymers; The core 3 occupies a certain volume to change the external dimensions of the mercury release device. The shape of the amalgam layer 2 is basically close to spherical. The amalgam layer is made of SnZnHg alloy material, and the mass content of mercury in the amalgam layer is 30%; the coating 1 is made of Al 2 o 3 made with a thickness of 50um. The mercury releasing device can be made into a low-power ultraviolet sterilizing lamp, an electrodeless lamp, and the like.

Embodiment 2

[0016] It is another mercury release device for fluorescent lamps, which is composed of a film, an amalgam layer and a core. The film is densely covered on the outer surface of the amalgam layer, and the core is set inside the amalgam layer; the core is made of ceramics, and its volume It can be adjusted arbitrarily, and the external dimensions of the mercury releaser can be changed by occupying a certain volume, so as to facilitate the application of lamps; the shape of the amalgam layer is basically close to spherical, and it is made of AgSnZnHg alloy material, and the mass content of mercury in the amalgam layer is 50%; the coating is made of ZnO 2 Made with a thickness of 80um. The mercury release device can be made into 3U, spiral lamp, ring, 2D lamp and so on.

Embodiment 3

[0018] As shown in Figure 2, it is a mercury release device for the third fluorescent lamp, which is composed of an amalgam layer 2 and a coating 1, the coating 1 is densely covered on the outer surface of the amalgam layer 2, and the amalgam layer 2 is made of BiSnZnHg alloy material , the mass content of mercury in the amalgam layer 2 is 40%; the covering film 1 is made of fluorescent powder with a thickness of 50nm. Can be made into 2D, 2U and other compact lamps.
