Embodiment 1

[0035] see figure 1 and figure 2 As shown, this embodiment provides a UV LED module, including a UV LED chip array 102, and the UV LED chip array 102 includes a plurality of small-sized UV LED chips 1021 arranged regularly. Specifically, its size ranges from 1 to 150 μm, which can be called Mini or Micro UV LED chip 1021 . The spacing between chips is less than 2mm.

[0036] This embodiment intends to arrange small-sized UV LED chips 1021 on the carrier board 101 by way of array arrangement. On the same carrier board area, more UV LED chips 1021 can be integrated. On the one hand, UV LED chips 1021 can be integrated. The chip 1021 works in the area with the highest electro-optical conversion efficiency, while keeping the total light intensity constant and reducing heat generation. On the other hand, the array distribution is used to facilitate distributed heat dissipation to speed up heat dissipation. The size of the heat sink can also be greatly increased. Reduced to impr...

Abstract

The invention discloses a UV LED module, which comprises a plurality of UV LED chips which are distributed in an array, the distance between the chips is less than 2mm, and the size of each UV LED chip is 1-150 microns; and the UV LED chips are arranged on the carrier plate in a huge transfer mode. According to the UV LED module provided by the embodiment of the invention, UV light is emitted by afew UV LED chips in the past, and the light is changed to be emitted by tens of or even hundreds of thousands of Mini or Micro UV LED chips, on one hand, the total light intensity can be kept unchanged, the UV LED chip works in the area with the highest electro-optical conversion efficiency, heating is reduced, on the other hand, heat dissipation is accelerated through distributed heat dissipation, the size of the heat sink can be greatly reduced, portability is improved, and the service life is prolonged.

Description

technical field [0001] The invention belongs to the technical field of LEDs, in particular to a UV LED module. Background technique [0002] Ultraviolet LEDs generally refer to LEDs with a luminous center wavelength below 400nm, but sometimes they are called near-ultraviolet LEDs when the luminous wavelength is greater than 380nm, and deep-ultraviolet LEDs when they are shorter than 300nm. Ultraviolet LEDs (UV LEDs) are mainly used in biomedicine, anti-counterfeiting identification, purification (water, air, etc.), computer data storage, and military affairs. And with the development of technology, new applications will continue to appear to replace the original technology and products, and ultraviolet LEDs have broad market application prospects. [0003] Due to the bottleneck of luminous efficiency, the current ultraviolet LEDs encounter difficulties in high-power light sources, and some applications of ultraviolet LEDs have put forward requirements for their power. Espe...
