Problems solved by technology

However, this will increase the manufacturing cost of the transparent encapsulation part 95'
Moreover, since the light-transmitting encapsulation part 95' protrudes from the housing 91', it is not conducive to the subsequent SMT or other manufacturing processes of the LED encapsulation structure 90'.

Abstract

The invention discloses a light-emitting diode packaging structure comprising a shell, a light-emitting diode chip and a light-transmitting packaging part, wherein the shell is provided with a concave part and a plurality of projecting parts; the light-emitting diode chip is arranged in the concave part and covers the light-transmitting packaging part in the concave part; and the plurality of projecting parts are arranged in the concave part or at the edge of the shell. The light-emitting diode packaging structure enables the surface of the light-transmitting packaging part to be rugged through the plurality of projecting parts, thus increasing the diffusion angle of the light rays and improve the light producing efficiency of the light rays.

Description

【Technical field】 [0001] The present invention relates to a light-emitting diode packaging structure, in particular to a light-emitting diode packaging structure in which a plurality of protrusions are provided to make the surface of the light-transmitting packaging part into an uneven shape. 【Background technique】 [0002] Liquid crystal display (liquid crystal display, LCD) is a flat panel display device (flat panel display, FPD) that uses the characteristics of liquid crystal materials to display images. Power consumption and other advantages have become mainstream products in the entire consumer market. However, the liquid crystal material of the liquid crystal display cannot emit light on its own, and an external light source must be provided. Therefore, a backlight module needs to be provided in the liquid crystal display to provide the required light source. [0003] Generally speaking, backlight modules can be divided into two types: side-type backlight modules and ...
