Problems solved by technology

However, the cost of this method is very expensive, and if the uniform distribution of light is to be maintained, a considerable distance must be kept between the red, blue, green and yellow LEDs, which will also increase the structural depth of the light-emitting device and weaken the light emission. Utilization
In this way, it will not only be unfavorable for RBG color mixing when applied to large-size liquid crystal displays, but also fail to meet product expectations in terms of luminance and light uniformity.

Abstract

The invention provides a light source light emitting device, a direct-type backlight module with the light-emitting device, a light box module, a planar light radiator, an LCD picture screen, a digital electronic device and a manufacturing method of the light-emitting device and the related products. The light emitting device comprises a plurality of long strip-shaped first light guide structures, a second light guide structure and a light source, the second light guide structure is adjacently spliced with two first light guide structures for receiving and containing the light source in a space which is combined by the two adjacent first light guide structures and the second light guide structure, wherein, patterned reflection layers are formed on the surfaces of the first light guide structures and the second light guide structure which are positioned at the same side of the light source and close to the periphery and the bottom part of the light source, at least optical reflection structures are additionally covered on the patterned reflection layers which are positioned at the bottom surfaces of the first light guide structures and the second light guide structure, thereby allowing light rays emitted by the light source to pass through the patterned reflection layers and the optical reflection structures for diffusion and reflection, improving the light uniformity, promoting the color mixing and reducing the occurrence of a dark band.
