Abstract

Provided is an LED light-emitting device which comprises a bearing module, a plurality of ultraviolet ray light-emitting diode chips and a light-transmitting packaging module. The ultraviolet ray light-emitting diode chips are arranged on the surface of the bearing module and are used for emitting ultraviolet rays, and dominant wavelengths corresponding to the ultraviolet rays emitted by the ultraviolet ray light-emitting diode chips are different. The ultraviolet rays emitted by the ultraviolet ray light-emitting diode chips, of which any two dominant wavelengths are similar, can be overlapped, and the ultraviolet rays emitted by the ultraviolet ray light-emitting diode chips can be overlapped to form a wavelength range covering at least 20 nm. The packaging module is arranged on the bearing module, and the ultraviolet ray light-emitting diode chips are wrapped by the packaging module. Therefore, the invention provides the LED light-emitting device capable of outputting the ultraviolet rays, having broader spectrum.

Description

technical field [0001] The present invention relates to a lighting device, and in particular to an LED lighting device. Background technique [0002] The commonly used ultraviolet (UV) curing process is roughly as follows: add a photoinitiator (or photosensitizer) to the resin, and after absorbing the ultraviolet (UV) in the LED light-emitting curing device, active free radicals or ionic radicals are generated to initiate polymerization, The cross-linking and continuous reaction makes the resin (UV coating, ink, adhesive, etc.) change from liquid to solid in a few seconds to a few minutes. [0003] However, the UV LEDs of commonly used LED light-emitting curing devices have a narrow-band output concentrated at a specific wavelength (+ / -10nm), that is, the wavelength range corresponding to the UV LEDs of commonly used light-emitting curing devices is approximately 10 nanometers. Therefore, resins (UV coatings, inks, adhesives, etc.) that require different UV curing condition...
