The patent is concerned a package structure that an LED light source can generate a high-brightness, high-efficiency, and high-uniformity luminance distribution through the structure. If it is further arranged to form a backlight module, the luminance and image quality of a display panel can be improved.

本發明之發光二極體均光結構可產生高均光度(其均勻度高達90%以上)、高輝度以及薄厚度之背光模組，相較於邊射型（Side Emitting）發光二極體背光模組，此背光模組更可應用於較大尺寸之平面顯示器或廣告燈箱，藉以得到高品質的顯示效果。

The patent can be applied to a backlight module for a general advertising light box or an LCD display panel, instead of a conventional fluorescent backlight source or a side-emitting type LED backlight module, and can also be applied to general indoor lighting fixtures to produce high-efficiency and high-uniformity of illumination.
