Dysprosium lamp is a high intensity gas discharge lamp，It is a kind of high light efficiency (75lm/w or more), high color rendering dominance (color index 80 or more).，New gas discharge light source with long life，It is a kind of metal halide lamp with high luminous efficiency, good color rendering and high brightness，It uses the injected dysprosium iodide, thallium iodide, mercury and other substances to emit its characteristic intensive spectrum，Use the appropriate ballast and trigger。

Main uses:

(1) As an additive for NdFeb permanent magnets, adding about 2~3% dysprosium to this magnet can improve its coercivity, the demand for dysprosium is not large in the past, but with the increase in demand for NdFeb magnets, it becomes a necessary addition element, grade must be in 95 ~ 99.At around 9%, demand is also increasing rapidly。
(2) dysprosium used as a phosphor activator, dysprosium trivalent is a promising single light-emitting center of the activation ion of trichromic light-emitting materials, it is mainly composed of two emission bands, one is yellow light emission, the other is blue light emission, dysprosium-doped light-emitting materials can be used as trichromic phosphor。
(3) Dysprosium is a necessary metal raw material for the preparation of large magnetostrictive alloy Terfenol alloy, which can enable some precision activities of mechanical movement to be realized。
(4) Dysprosium metal can be used as a magneto-optical storage material, with high recording speed and reading sensitivity。
(5) For the preparation of dysprosium lamps, the working substance used in dysprosium lamps is dysprosium iodide, this lamp has the advantages of large brightness, good color, high color temperature, small size, stable arc, etc., has been used in film, printing and other lighting sources。
(6) Because dysprosium has a large neutron capture cross-sectional area, it is used in the atomic energy industry to determine the neutron spectrum or as a neutron absorber。
(7) Dy3Al5O12 can also be used as a magnetic working substance for magnetic refrigeration。With the development of science and technology, the application field of dysprosium will continue to expand and extend

Scope of application:

It has high luminous efficiency, good color rendering, high brightness, dysprosium lamp has a variety of shapes such as spherical, tubular, ellipsoid to meet the needs of different uses, and the corresponding ballast and trigger are required when used。
Daylight-colored dysprosium lamps are widely used in tall factories, squares, construction sites, exhibition halls, halls, billboards, shopping malls, stadiums (pavilions), as well as color film production, color television broadcasting, color printing and other occasions。
Reflective daylight dysprosium lamps have a reflective layer, the lamp and the lamp are combined into one, no need to match another lamp, easy to use。The light source has large radiation intensity and small infrared radiation in the broad spectral region from blue violet light to orange red light. It has the characteristics of light concentration and high light utilization rate. It is an ideal light source for agricultural experiments, cultivation of crops and accelerating plant growth。Suitable for all kinds of artificial climate box, artificial biological box, greenhouse and other occasions as artificial radiation light source。

Note:

Many workplaces operate at night to avoid daytime heat and high electricity consumption，The use of dysprosium lamps for night lighting is quite common，However, dysprosium lamps once used improperly，The ultraviolet light it emits will have a bad effect on the eyes of workers，Severe cases may lead to electro-optical ophthalmia，The main symptoms were stinging eye pain, foreign body sensation, tearing, photophobia, blurred vision and so on。In order to protect the occupational health of workers, the relevant construction units are reminded to do the following work when using dysprosium lamps:
(1) Select qualified dysprosium lamps according to the regulations, use dysprosium lamps correctly, pay attention to maintaining the irradiation distance, and strengthen maintenance and repair to ensure the normal use of dysprosium lamps;
(2) Formulate and implement various production safety rules and regulations to enhance workers' individual protection awareness;
(3) Strengthen personal occupational health protection, wear protective masks or protective glasses;
(4) Do a good job of UV intensity detection in the workplace to prevent excessive UV intensity;
(5) Organize workers to undergo occupational health examination according to regulations
