Embodiment 1

[0018] see figure 1 and figure 2 , the present invention relates to a packaging structure for UV LED lamps, including a lamp holder 10, four UV chips 20 and a glass cover 30 for covering the lamp holder 10, the top surface 11 of the lamp holder 10 is concave downward There is a groove 12, and four UV chips 20 are arranged in a rectangular array on the bottom surface 121 of the groove 12, and then each UV chip 20 is encapsulated by UV LED chip fusion glass, and the UV LED chip and the lamp holder 10 are electrically connected. connect.

[0019] The glass cover plate 30 is bonded and covered on the top surface 11 of the lamp holder 10 through an adhesive layer 40, and a metal film layer 32 is plated on the lower surface 31 of the glass cover plate 30 corresponding to the adhesive layer 40. In this embodiment, Metal film layer 32 adopts aluminum film layer, and the thickness of aluminum film layer is controlled at 3-5 microinch; In order to meet the requirement that the alumi...

Embodiment 2

[0021] The structure of this embodiment is substantially the same as that of Embodiment 1, the same structure will not be described in detail, and only the differences will be described. In this embodiment, the metal film layer 32 is a gold film layer, and the thickness of the gold film layer is controlled at 1-3 microinches. The shape and size of the gold film layer meet the requirement of covering the adhesive layer 40 to block the irradiation of ultraviolet light on the adhesive layer 40 .

[0022] It should be noted that the adhesive layer 40 of the present invention can also be an inorganic material adhesive layer, and the metal film layer 32 is plated on the lower surface 31 of the glass cover 30 to increase the optional range of adhesive layer materials.

Abstract

The invention provides a packaging structure of a UVLED lamp and the UVLED lamp. The packaging structure comprises a lamp holder, a UV wafer and a glass cover plate for covering the lamp holder, wherein a downwards recessing groove is arranged in the top face of the lamp holder, the UV wafer is fixed on the bottom of the groove, the glass cover plate is bonded and covered on the top face of the lamp holder through an adhesive layer, and a metallic film layer is plated on the lower surface of the glass cover plate corresponding to the adhesive layer. When the glass cover plate covers the lamp holder, the metallic film layer wraps and is bonded the adhesive layer. According to the packaging structure, a metallic film layer is arranged on the glass cover plate and covers the adhesive layer to block irradiation UV light on the adhesive layer, thereby preventing aging of the adhesive layer. The UV LED lamp employs an adhesive layer packaging structure which is low in cost and simple for operation. In addition, the packaging structure has higher mechanical strength, and the material selecting scope of the adhesive layer is expanded.

Description

technical field [0001] The invention relates to the field of LED lighting equipment, in particular to a packaging structure of a UV LED lamp and a UV LED lamp including the packaging structure. Background technique [0002] UV LED lamp is a kind of LED lamp, which is invisible light of single wavelength, generally below 400nm. Through professional design, UV LED lamps can present different shapes and different irradiance spots to meet the production needs of edge banding, printing and other fields. It has super long life, cold light source, no heat radiation, stable performance, less replacement times and has bactericidal effect, which is safer and more environmentally friendly than traditional light sources. Various fields have a wide range of applications. [0003] At present, when UV LED lamps are packaged, the glass cover is usually directly welded and fixed on the lamp holder, or the glass cover is bonded and fixed on the lamp holder by using organic materials such as...
