Problems solved by technology
[0004] At present, the luminous power of ultraviolet LED is not high. In addition to the improvement of chip production level, packaging technology also has an important impact on the characteristics of LED.
The existing UV LED packaging materials mainly include organic materials such as epoxy resin and silica gel. Due to the high energy of ultraviolet light, it is easy to change the performance of organic packaging materials and make them yellow and aging, resulting in the performance and service life of UV LEDs. decline

The invention relates to the technical field of ultraviolet LED encapsulating, and discloses an ultraviolet LED encapsulator. The ultraviolet LED encapsulator comprises an upper light transmitting hollow casing and a lower light transmitting hollow casing respectively arranged on the two sides of an ultraviolet LED; opening ends are arranged on one side of the upper light transmitting hollow casing and on one side of the lower light transmitting hollow casing; the ultraviolet LED comprises a substrate and a plurality of wafers arranged on the substrate; one side of the substrate seals the opening end of the upper light transmitting hollow casing, and the other side of the substrate seals the opening end of the lower light transmitting hollow casing; the upper light transmitting hollow casing and the lower light transmitting hollow casing are internally vacuum or filled with the gas. The encapsulator encapsulates the ultraviolet LED through the light transmitting hollow casings and thefilling gas in the light transmitting hollow casings or vacuuming, the whole encapsulator does not use an organic encapsulating material, the ageing of the organic encapsulating material by the ultraviolet light is completely avoided from the source, the performance of the ultraviolet LED is effectively improved, and the service life of the ultraviolet LED is prolonged.
Description
technical field [0001] The invention relates to the technical field of ultraviolet LED packaging, in particular to an ultraviolet LED packaging device. Background technique [0002] Ultraviolet (UV) is a general term for radiation with wavelengths from 100nm to 400nm in the electromagnetic spectrum. According to different wavelengths, ultraviolet rays are generally divided into three bands: A, B, and C. UV-A is 400-315nm, UV-B is 315-280nm, and UV-C is 280-100nm. In the UV LED market application, the main application market of UV-A is curing, ink printing and other fields, UV-B is mainly used in medical treatment, and deep ultraviolet UV-C is mainly used in sterilization and disinfection. [0003] Light Emitting Diode (LED for short) is more and more widely used in today's daily life and industry. It has low power consumption, fast luminous response, high reliability, high radiation efficiency, long life, no pollution to the environment, Many advantages such as compact str...
