Abstract

The invention discloses an adjustable ultraviolet light LED. The adjustable ultraviolet light LED comprises a bracket, a wafer and colloid, wherein the wafer comprises multiple ultraviolet light chips of different wave bands; the ultraviolet light chips are arranged on the bracket in different sections; and the ultraviolet light chips are filled with the colloid. The invention also discloses a manufacturing method for the adjustable ultraviolet light LED. By virtue of the arrangement of the ultraviolet light chips of different wave bands in different sections, a better application operation can be achieved, and the same product can be multifunctional; and in addition, flexible adjustment can be realized so as to improve the practicability of the adjustable ultraviolet light LED.

Description

technical field [0001] The invention relates to the technical field of ultraviolet light LEDs, in particular to an adjustable ultraviolet light LED and a manufacturing method. Background technique [0002] Ultraviolet LEDs (UV LEDs) have established a market in the past 5 years in the field of hardening, drying, and bonding using ultraviolet light, that is, UV curing. With the advantages of high UV output power, small size and low power consumption, UV LEDs bring great value to the market of UV systems and the users of these systems. [0003] As UV curing technology using UV LEDs expands to the ink, adhesive, and coating industries, the UV LED market is expected to expand further. In addition, new uses such as disinfection and purification have been added. The performance of UV LEDs is not yet sufficient for disinfection and purification purposes. However, with the improvement of performance in the future, it is estimated that before 2018, part of the revenue of the UV LE...
