具体实施方式detailed description
本公开提供一种LED模块及LED阵列模组，为使本公开的目的、技术方案及效果更加清楚、明确，以下对本公开进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本公开，并不用于限定本公开。The present disclosure provides an LED module and an LED array module. In order to make the objectives, technical solutions and effects of the present disclosure clearer and clearer, the present disclosure will be described in further detail below. It should be understood that the specific embodiments described here are only used to explain the present disclosure, but not used to limit the present disclosure.
现有技术通常采用黑色光吸收物质制作LED模块的挡墙(边框)，以此来增加LED模块颜色的对比度，并减少广场干扰的问题。然而由于黑色光吸收物质会部分吸收LED模块发出的光，从而导致降低LED模块的发光亮度，并且所述黑色光吸收物质吸收LED模块发出的部分光后，还可能造成LED模块发光不均匀的问题。In the prior art, black light-absorbing materials are generally used to make the retaining wall (frame) of the LED module, so as to increase the color contrast of the LED module and reduce the problem of square interference. However, because the black light absorbing material partially absorbs the light emitted by the LED module, which results in the reduction of the luminous brightness of the LED module, and the black light absorbing material absorbs part of the light emitted by the LED module, it may also cause the problem of uneven light emission of the LED module .
基于现有LED模块所存在的问题，本公开实施例提供一种LED模块，其中，如图1和图2所示，所述LED模块10包括电路基板20，以及设置在所述电路基板20上的至少一个红光LED21、至少一个绿光LED22以及至少一个蓝光LED23，所述LED模块10四周均设置有挡墙30，所述挡墙30至少有一个区域掺杂有用于产生补偿光的量子点材料。Based on the existing problems of the existing LED module, an embodiment of the present disclosure provides an LED module, in which, as shown in FIGS. 1 and 2, the LED module 10 includes a circuit substrate 20, and is disposed on the circuit substrate 20 At least one red LED 21, at least one green LED 22, and at least one blue LED 23 of the LED module 10 are provided with a retaining wall 30 around the LED module 10, and at least one area of the retaining wall 30 is doped with quantum dots for generating compensation light material.
在本实施例中，通过在挡墙的特定区域掺杂量子点材料，当距离所述区域较近的LED发射出光束时，基于量子局限效应，所述LED发出的光束将激发所述区域中的量子点材料产生补偿的光束，所述量子点材料产生的补偿光束不仅可提升LED模块的发光亮度，还可降低LED模块中光的干扰现象并提升光的均匀性。In this embodiment, by doping quantum dot material in a specific area of the retaining wall, when the LED closer to the area emits a light beam, based on the quantum confinement effect, the light beam emitted by the LED will excite the light in the area The quantum dot material produced by the quantum dot material generates a compensated light beam. The compensation light beam generated by the quantum dot material can not only improve the luminous brightness of the LED module, but also reduce the light interference phenomenon in the LED module and improve the light uniformity.
