[0002] UV lamp as a kind of common ultraviolet light source, is widely used in curing, sterilization, medical field etc. In order to improve the optical performance and service life of UV lamp, usually set up silica gel lens on the outside of lampwick, for focusing light, protect lampwick and promote light efficiency.

[0003] In the existing UV lamp assembly process, the following steps are usually adopted: first, lamp panel is fixed in lamp shell, then a plurality of silica gel lenses are sequentially positioned corresponding to lampwick on lamp panel, finally, light shielding piece is covered, so that lens is fixed by the clamping action of lamp panel and light shielding piece. However, this assembly method has the following technical problems:

[0004] Lens positioning is difficult and prone to misalignment: since lens needs to be placed on lamp panel separately, and then covered with light shielding piece, in the assembly process, lens is prone to deviation due to external force or vibration, which leads to inaccurate alignment with lampwick, and affects optical performance and product yield.

[0005] Low assembly efficiency: the number of lenses corresponds to lampwick one by one, and lens cannot be fixed on light shielding piece in advance, which leads to complicated assembly process, low production efficiency and difficulty in meeting large-scale production demand. INVENTION CONTENTS
