The purpose of the present invention is to provide an LED indirect lighting module, an indirect lighting device, and a manufacturing method thereof which manufactures an LED lamp at low costs while minimizing the glaring of the LED lamp and designing various types of lighting devices. To achieve the purpose, the present invention comprises a substrate of a light transmitting material; a conductive layer formed on the substrate; and an LED chip mounted on the conductive layer. A circuit pattern unit in which the conductive layer is not eliminated is formed on the substrate. A light transmitting layer in which the substrate is exposed by eliminating the conductive layer is formed on the substrate. An LED indirect lighting device of the present invention passes light emitted from the LED chip through a reflection unit and a light transmitting substrate, thereby minimizing the loss of light energy. The LED indirect lighting device has the same brightness as when using a diffusion plate in the prior art. In the present invention, the light emitted from the LED chip is firstly reflected on the reflection unit, and then the light secondly passes through the substrate of the light transmitting material. Therefore, the glaring is prevented because the scattering of the light is bifariously executed and smooth lights are emitted. |
